1 1. INTRODUCTION

2 1. This is a securities fraud class action against Nuvelo, Inc. ("Nuvelo or the

3 "Company ) and certain of the Company's senior officers and directors for violations of the

4 Securities Exchange Act of 1934 (the "Exchange Act ) and Rule 1 Ob-5 promulgated thereunder, 17

5 C.F.R. §240.10b-5. This action is brought on behalf of all purchasers of the publicly traded

6 securities ofNuvelo between January 5, 2006 and December 8, 2006, inclusive (the "Class Period ),

7 including purchasers in Nuvelo's January 31, 2006 $119 million follow-on offering ("Follow-On

8 Offering ).

9 2. Nuvelo is a company engaged in the development and

10 commercialization of acute cardiovascular and cancer therapies. During the Class Period, the

11 Company's drug development pipeline included three acute cardiovascular drugs under

12 development: alfimeprase, recombinant nematode protein c2 ("rNAPc2 ) and a

13 inhibiting aptamer. However, the Company's lead cardiovascular development program -

14 to which the market attributed 80% of the Company's value and which the Company touted as its

15 path to profitably - was alfimeprase, a direct-acting thrombolytic agent, or blood clot dissolver.

16 3. Nuvelo obtained the rights to alfimeprase from Amgen, Inc. ("Amgen ), a

17 pharmaceutical company whose co-founder, George Rathmann ("Rathmann ), sat on Nuvelo's

18 board. Amgen had previously tried unsuccessfully to develop alfimeprase. Nevertheless, Nuvelo,

19 which had never successfully brought a drug to market, sought to capitalize on alfimeprase's

20 purported commercial potential, using it as a lever to raise money to keep the Company afloat, as

21 well as to line defendants' pockets.

22 4. At the time Nuvelo obtained the rights to alfimeprase in 2002, it was running out of

23 cash and in danger ofbecoming insolvent. After obtaining the rights to alfimeprase, Nuvelo merged

24 with Variagenics, Inc. ("Variagenics ) - another drug company that, like Nuvelo, had no products

25 with any near term revenue potential in the pipeline but, unlike Nuvelo, had $55.9 million in the

26 bank. Following the merger, Nuvelo jumped into clinical trials of alfimeprase, repeatedly boasting

27 of the purported results of the trials and the potential commercial success of drug. Before and during

28 the Class Period, the Company repeatedly used the alleged success ofthe alfimeprase trials to access

1 the market and obtain much needed cash to continue in operation, test its drug candidates and highly

2 compensate its executives, raising over $291 million in four public and private offerings, while

3 paying over $4.7 million in salary and cash bonuses to its top officers and directors, the defendants

4 here.

5 5. During the Class Period, Nuvelo conducted Phase 3 clinical trials for the use of

6 alfimeprase for the treatment of acute peripheral arterial occlusion ("PAO ) and catheter occlusion

7 ("CO ). Success of the Phase 3 trials was required to secure U.S. Food and Drug Administration

8 ("FDA ) approval and tap the commercial potential ofthe drug. Despite the fact they simply did not

9 have the clinical data to back up their statements, defendants repeatedly stated that alfimeprase had

10 already proved effective for the use for which it was being tested in clinical trials for the treatment of

11 PAO. Defendants further concealed a "target product profile necessary to commercialize the drug

12 for treatment of CO, as well as the fact that the FDA had imposed an extraordinary regulatory

13 standard, forty times more stringent than normal, for approval based on the Phase 3 CO trial.

14 6. Defendants' statements were based on the results ofPhase 2 trials completed prior to

15 the Class Period, which they claimed demonstrated the efficacy of the drug for the purposes for

16 which it was being tested in the Phase 3 trials. During the Class Period, defendants repeatedly touted

17 the Phase 2 results when discussing the likely success ofthe Phase 3 trials. Defendants claimed, for

18 example, that the Phase 2 trials had demonstrated that alfimeprase restored blood flow and allowed

19 patients to avoid open surgery when, in fact, defendants knew that the results of the Phase 2 trial in

20 PAO could have been the result ofthe catheter used to inject the drug being pushed through the clot,

21 and there was no way to reliably determine how much, if any, of the positive results were due to

22 alfimeprase. Incredibly, despite their knowledge of these adverse facts, defendants told investors

23 that the Phase 3 trials represented a "low risk path to regulatory approval that would be "rapid to

24 market.

25 7. In making these statements, defendants misrepresented the significance ofthe Phase 2

26 results, and failed to accurately or fully disclose the risks associated with the ongoing clinical trials.

27 Nuvelo's periodic filings with the Securities and Exchange Commission ("SEC ) prior to and during

28 the Class Period similarly misrepresented the risks associated with the Phase 3 trials. The risk

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -2- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 6 of 79

1 warnings included in those filings included standard boilerplate suggesting that success ofthe Phase

2 3 trials was not guaranteed. However, those warnings failed to specifically disclose known risks that

3 undermined the purported Phase 2 results. Taken together, these statements misled the investing

4 public about the significance of the Phase 2 trial results and the risks then presented in the Phase 3

5 trials.

6 8. In particular, Nuvelo and its officers failed to adequately warn investors that: (i) the

7 purportedly positive Phase 2 results could be the result of blood clots in certain patients with PAO

8 simply being broken up by the insertion of the catheter into the artery, rather than dissolved by the

9 action of the drug, a matter which had been discussed internally at Nuvelo even before the Phase 2

10 trials were completed; (ii) in the Phase 3 CO trial, the FDA had imposed a much more stringent p-

11 value requirement on Nuvelo to demonstrate success at a statistical significance level that wasforty

12 times more stringent than what the market believed; (iii) the market opportunity for the drug for

13 PAO was much smaller than represented to analysts and the market because ofcompetition from off-

14 label use of other drugs and mechanical clot-busting techniques, the potential impact of which was

15 not timely or accurately disclosed to investors; and (iv) Nuvelo had an undisclosed "target product

16 profile which would be necessary to meet in order for the Company to market alfimeprase for CO,

17 such that the Company would not proceed to market alfimeprase for that indication ifthe trial results

18 did not meet that profile, even ifthe drug was otherwise qualifiedfor FDA approval.

19 9. As a result of these false and misleading statements, Nuvelo's securities traded at

20 dramatically inflated prices during the Class Period. At the outset of the Class Period, Nuvelo

21 announced that it had secured a commitment from pharmaceutical giant Healthcare A.G.

22 ("Bayer ) to fund the Phase 3 trials of alfimeprase, which securities analysts and investors

23 reasonably understood as an endorsement of defendants' statements regarding the reliability of the

24 Phase 2 results, the ease with which efficacy would be demonstrated in the Phase 3 trials and the

25 market size for the drug. Nuvelo immediately took advantage ofthese inflated prices by selling over

26 7.5 million shares of common stock in the Follow-On Offering, realizing proceeds of $119 million.

27 10. On December 11, 2006, Nuvelo stunned investors by announcing that both of the

28 Phase 3 trials of alfimeprase had failed. The Company also revealed that the purportedly positive

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -3- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 7 of 79

1 results in the Phase 2 PAO trial had simply been the result ofthe catheter used to deliver alfimeprase

2 being pushed through a blood clot and breaking up the clot, rather than any action of the drug itself.

3 In fact, this explanation for the positive Phase 2 results had been discussed repeatedly in

4 Company-wide meetings prior to the Class Period, creating internal concern among professional

5 employees at Nuvelo who disputed the potential of alfimeprase to deliver on the promises being

6 made by the Company. The Company further revealed that the Phase 3 CO trial had failed, both

7 because the FDA had imposed a much more stringent test of statistical significance than typically

8 required and because - even at standard levels of statistical significance - the drug had failed to meet

9 the Company's undisclosed product performance standards based on market size and competition,

10 thereby rendering it unmarketable. In fact, the Company said that although the CO trial had

11 produced statistically significant results when measured by traditional standards, and the Company

12 could probably obtain approval by doing another trial, the Company had no interest in doing so.

13 These internally known, but undisclosed, risks which had come to fruition were publicly revealed for

14 the first time when the reasons for the failure ofthe Phase 3 trials were announced, causing Nuvelo's

15 stock and options prices to instantly collapse, the stock falling from $19.55 to $4.05 per share and

16 the options becoming worthless. This one day loss of nearly 80% of Nuvelo's value injured

17 thousands of investors who had purchased Nuvelo's inflated stock and options in reliance on

18 defendants' misrepresentations about the Phase 2 results, the Phase 3 trials, and the efficacy and

19 marketability of alfimeprase.

20 11. Following the Class Period, further details emerged regarding the extent to which

21 defendants had deliberately hidden and misrepresented the risks associated with the Phase 3 trials.

22 On June 26, 2007, defendants revealed that the FDA-imposed standard for statistical significance in

23 the CO trial required alfimeprase to establish a false positive rate of only 1 in 1,250 cases - a level

24 virtually unheard of in the industry and far more stringent than the typical rate applied by the FDA of

25 5 in 100. Plaintiffs have been unable to identify any other trial where the FDA had imposed such a

26 stringent standard. Defendants further revealed that alfimeprase had failed to meet the Company's

27 previously undisclosed internal marketing guidelines for the drug. These disclosures, along with the

28 news that Bayer had pulled out of any further efforts to develop the drug, caused an additional 20%

1 drop in Nuvelo's share price, causing additional injury to Class members who continued to hold their

2 shares through the date of these announcements.

Defendant Ted W. Love ("Love ) is, and at all relevant times has been, Chief 14 Executive Officer ("CEO ) and Chairman of the Board of Nuvelo. Love joined the Company in 15 January 2001 and was appointed CEO in March 2001. According to CW 1 (infra, ¶22), "everything 16 went through Ted at Nuvelo, and as a result, Love was constantly kept apprised of information 17 concerning Nuvelo's drug candidates, including its main candidate, alfimeprase. Love has also 18 served as the Company's Chief Operating Officer. Love has served as a director of the Company 19 since February 2001 and became Chairman of the Board in September 2005. Love previously 20 worked at Theravance, Inc., where he served as Senior Vice President ("VP ) ofDevelopment from 21 February 1998 to January 2001. Love was employed for six years at Inc. ("Genentech ), 22 where he oversaw drugs in development including TNKase (Tenecteplase), a single-bolus 23 thrombolytic agent, used off-label as a treatment for PAO. Love signed Nuvelo's filings with the 24 SEC during the Class Period, including the Form 10-K for the fiscal year ending December 31, 2005 25 and the Forms 10-Q for the first three quarters of 2006. 26 18.

1 in January 2003 as Senior Director ofFinance. In July 2004 he was promoted to VP of Finance and

2 CAO. From November 2005 to July 24, 2006 he served as acting CFO. Titus' employment with the 3 Company was terminated on September 1, 2006. Titus signed Nuvelo's filings with the SEC during 4 the Class Period, including the Form 10-K for the fiscal year ending December 31, 2005 and the 5 Form 10-Q for the first quarter of 2006. 6 19. Defendant Michael D. Levy ("Levy ) was at all relevant times, Nuvelo's Senior VP, 7

9 alfimeprase, and regularly provided investors with information regarding those trials, including on

10 regular conference calls with analysts . Levy joined Nuvelo in November 2004. 11 20. Defendants Love, Titus, and Levy are collectively referred to herein as the 12 "Individual Defendants. According to Nuvelo's Proxy Statement, filed with the SEC on April 14, 13 2006, the Company only had four executive officers as of March 31, 2006, including Individual 14 Defendants Love, Levy and Titus. 15 IV. CONFIDENTIAL WITNESSES 16 21. The allegations of defendants' improper conduct alleged in this Consolidated 17 Complaint for Violations of Federal Securities Law ("Complaint ) are made upon information and 18 belief, based upon investigation of counsel, including a review of SEC filings issued by Nuvelo, 19

20 news articles, securities analyst reports, advisories about the Company, press releases and other

21 public statements issued by the Company or its representatives, media reports about the Company,

22 and the first-hand accounts of four confidential witnesses, including the following: 23 22. Confidential Witness No. 1 ("CW 1 ) was a director of research with Nuvelo during 24 the Phase 2 clinical trials of alfimeprase. Although CW 1 did not work directly on the alfimeprase 25 trials , he had regular contact with other employees who did. CW1 left Nuvelo in 2005 , around the 26 time the Phase 2 clinical trials were being completed, because s/he was convinced that neither 27

28 alfimeprase nor the drug candidates s/he was working on had potential for commercial success.

1 CW1 said that, during his/her tenure, other Nuvelo employees had expressed similar doubts to

2 him/her about alfimeprase's potential, including VP ofResearch Walter Funk, who reported directly

3 to, and had frequent communications with, Love about alfimeprase and Nuvelo's other drug 4 candidates. 5 23. CW2 was a principal investigator for one of the Phase 3 clinical trials for PAO (i. e., 6 7 NAPA - see ¶46-49). As such, CW2 has direct personal knowledge ofthe protocols for and conduct

8 of those trials.

9 24. CW3 was employed by Nuvelo in clinical operations during the Phase 2 trials of

10 alfimeprase. CW3 worked on the Phase 2 clinical trials for CO and PAO. CW3 left Nuvelo before 11 the Phase 2 trials were completed. CW3 worked at Nuvelo while the Company was drafting the 12 protocols for the Phase 3 trials. 13 25. CW4 was a director of clinical operations with Nuvelo during the Phase 2 trials of 14

15 alfimeprase and reported to Steven R. Deitcher ("Deitcher ), VP ofMedical Affairs, who reported to

16 Love.

17 V. BACKGROUND TO THE CLASS PERIOD

18 26. Alfimeprase is a potential clot-dissolving thrombolytic agent which defendants

19 claimed degrades or dissolves clot-forming fibrin, a protein that provides the scaffolding for blood

20 clots. Alfimeprase is a derivative of an enzyme found in the venom of the southern copperhead

21 snake. Unlike other thrombolytics, alfimeprase is not a plasminogen activator. Instead, it

22 purportedly acts to degrade fibrin directly in order to dissolve the clot.

23 27. During and prior to the Class Period, Nuvelo claimed that alfimeprase can be bound

24 and neutralized by serum alpha(2)-macroglobulin, a naturally occurring protein in the blood, which

25 "traps alfimeprase to prevent its release into the systemic circulation. Nuvelo promoted alfimeprase

26 as having a lower risk of bleeding due to its rapid degradation in the bloodstream, thereby limiting

27 its activity to the area where it is administered. 28

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -8- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 12 of 79

1 A. Nuvelo Bets Its Future on the Commercialization of Alfimeprase

2 28. At the time Love joined Nuvelo in January 2001, the Company had only $2.7 million

3 in cash. Around the same time, Amgen co-founder Rathmann, who had been named Chairman of

4 Nuvelo's Board in February 2000 and had served as President and CEO from May 2000 until Love

5 joined the Company, provided a $20 million line of credit to the Company. A $21 million private

6 placement in August 2001 kept the Company going. Still, by the end of 2001 Nuvelo's prospects

7 were growing dim; the Company was running low on cash again and had no drugs ready to move

8 into clinical trials. Desperate for cash and needing a way to reel in investors, Love sought to

9 capitalize on the Company's newfound relationship with Amgen, via Rathmann, by taking over the

10 development and commercialization of alfimeprase.

11 29. In January 2002 Love caused Nuvelo to enter into a collaboration agreement with

12 Amgen to co-develop and commercialize alfimeprase. Under the terms of the collaboration

13 agreement, Nuvelo would lead all clinical development activities and Amgen would be responsible

14 for all manufacturing activities. Amgen neither promised nor delivered any up-front payments -

15 Nuvelo was required to match Amgen's spending to date, and to share all development costs

16 thereafter equally. Under the terms of the collaboration agreement, after Nuvelo's investment

17 reached the same level as Amgen's, Amgen could then continue to jointly develop alfimeprase with

18 Nuvelo or it could simply license alfimeprase to Nuvelo, requiring Nuvelo - a small company with

19 no revenue-producing products and nothing in its pipeline - to assume full financial responsibility

20 for the commercialization of a drug which for years had already proven commercially non-viable.

21 30. With alfimeprase in hand to build a pipeline around and his newfound relationship

22 with Amgen to lend credibility, Love turned his attention to raising money. Instead ofturning to the

23 capital markets, Nuvelo acquired Variagenics, a pharmacogenomics company in Cambridge,

24 Massachusetts, which had $55.9 million in the bank. The merger, completed in February 2003,

25 served primarily as a financing vehicle for Nuvelo.

26 31. Flush with cash, Nuvelo began conducting clinical trials ofalfimeprase as a treatment

27 for dissolving blood clots in the legs (PAO) and around catheters in patients undergoing treatment

28 (CO). Nuvelo used the buildup it had created around alfimeprase as a tool for raising much needed

cash to continue its business and fund the exorbitant pay packages provided to insiders. Nuvelo

2 began a pattern of announcing positive news about the drug shortly before selling securities to raise

3 additional operating cash. For example:

4 In a September 25, 2003 press release, Nuvelo positively reported the successful completion of its interim analysis of data from its Phase 2 trial with alfimeprase for 5 the treatment of PAO. Just a week later, Nuvelo announced the sale of 10 million shares of its common stock placed directly with institutional investors, receiving net 6 proceeds of $24.5 million. The Company paid Love a salary of $583,583 in 2003 more than double the amount the Company paid its President and CEO in 1999. 7 The Company also awarded Love 133,332 options in 2003.

8 In a February 5, 2004 press release, Nuvelo announced that it anticipated completing enrollment ofthe Phase 2 alfimeprase trials for both PAO and CO by April 2004, and 9 that it expected to initiate the Phase 3 alfimeprase trial in PAO in the second half of 2004. Two weeks later, on February 19, 2004, Nuvelo announced plans to offer 4 10 million shares of its common stock in an underwritten public offering; it ultimately sold 5.75 million shares, netting proceeds of $74.8 million. Nuvelo paid Love a 11 salary of $596,000 in 2004 and awarded him 500,000 options. Levy, who joined the Company in November 2004, was awarded 175,000 options. 12 On September 30, 2004, Nuvelo announced that Phase 2 trial results showed the 13 potential of alfimeprase to treat PAO. On December 6, 2004, Nuvelo announced data from its Phase 2 clinical trial in CO that it claimed showed the potential of 14 alfimeprase to be approved as a fast-acting drug to clear blocked catheters. Little more than a month later, on January 24, 2005, the Company commenced a public 15 offering which was completed on February 7, 2005, when the Company received proceeds of approximately $73 million in exchange for 9.775 million shares of 16 newly-issued common stock. The Company paid Love $800,000 in combined salary and bonus in 2005 and awarded him 750,000 options. The Company paid Levy a 17 salary of $381,250 and awarded him 200,000 options. The Company paid Titus a salary of $226,667, a bonus of $65,000 and awarded him 175,000 options. 18 B. Amgen Refuses to Fund Further Efforts to Commercialize 19 Alfimeprase

20 32. By November 2004, the level ofNuvelo's financial investment in the development of

21 alfimeprase had reached that of Amgen. Amgen then had an option to either pay 50% of the drug's

22 development costs going forward or to license alfimeprase to Nuvelo. Amgen pulled the plug on the

23 project, telling Nuvelo it would not further fund any efforts to commercialize alfimeprase.

24 33. Amgen's decision left Nuvelo with an incredible cash burn rate and no big-pharma

25 investment partner. Moreover, under the terms of the agreement terminating the contract between

26

27 Between May 2000 and January 2001, Rathmann, served as CEO and drew no salary. 28

1 Nuvelo and Amgen for the joint development and commercialization of alfimeprase, in order to

2 obtain licensing rights to alfimeprase from Amgen, Nuvelo had to pay Amgen $8.5 million by

3 November 5, 2004. Heading toward the end of its fiscal year 2004 with less than $17 million in cash

4 on its books, Nuvelo again primed the capital markets with positive news about alfimeprase.

5 34. On December 6, 2004, Nuvelo announced that data from a Phase 2 clinical trial in CO

6 showed that alfimeprase had the potential to restore function in patients with blocked catheters and

7 to be a well tolerated therapy for use in catheter occlusion. "We are encouraged by these results and

8 will work rapidly to initiate a Phase 3 clinical development program in this second potential

9 indication, the Company stated in the December 6, 2004 press release. "Alfimeprase is the

10 cornerstone of a growing cardiovascular franchise at Nuvelo. The catheter occlusion data ...

11 reflects the expanded potential opportunity we have with this versatile and unique agent. Shortly

12 thereafter, on January 24, 2005, the Company announced a proposed public offering of 7 million

13 shares of common stock, and on February 7, 2005, it announced the completion of its sale of 9.775

14 million shares, receiving proceeds of approximately $73 million.

15 35. By the end of fiscal year 2005, the Company' s prospects again were bleak. Nuvelo

16 had less than $38 million in cash, and again turned to alfimeprase to bail it out of potential

17 insolvency. On December 14, 2005, the Company announced it had received a Special Protocol

18 Assessment ("SPA ) agreement from the FDA for its second Phase 3 trial of alfimeprase for the

19 treatment of acute PAO. Defendants claimed that having the FDA SPA agreement in place

20 "solidifie[d] the regulatory pathway to approval for alfimeprase.

21 36. Throughout 2005, Nuvelo continued to report on the progress towards Phase 3

22 alfimeprase trials in CO and PAO, each time making material misrepresentations about the results of

23 the Phase 2 trials. On February 15, 2005, the Company again touted the results of the Phase 2

24 clinical trials in connection with the release of its FY04 results, with Love claiming that Nuvelo had

25 become "a late-stage product company with multiple development opportunities focused on acute,

26 hospital based cardiovascular care. On April 18, 2005, the Company announced that it had begun

27 patient enrollment in the Phase 3 alfimeprase trial in PAO, representing that "alfimeprase can restore

28 arterial blood flow within four hours of initiation of dosing [and] demonstrated a favorable safety

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ - 11 - 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 15 of 79

1 profile. On May 26, 2005, Nuvelo announced that it had finalized the design of the Phase 3

2 program for alfimeprase in CO, again misrepresenting that "[p]reviously announced results from a

3 Phase 2 multi-center, randomized, double-blind study in 55 patients with occluded central venous

4 catheters, demonstrated the ability of alfimeprase to restore function to occluded catheters in as early

5 as five minutes. On December 14, 2005, when Nuvelo announced that it had received the SPA

6 agreement from FDA for the Phase 3 trial of alfimeprase in PAO, the Company once again

7 misrepresented that the Phase 2 trial of alfimeprase in PAO "demonstrated that alfimeprase can

8 restore arterial blood flow.

9 37. However, even where blood flow was increased through a clotted blood vessel, the

10 Phase 2 PAO trial was unable to reliably determine how much ofthat result was due to the action of

11 alfimeprase versus simply the effect ofthe catheter breaking up the clot as the drug was administered

12 through the catheter. In fact, this precise risk had been discussed by CW 1 prior to the Class Period

13 with high ranking officers ofNuvelo, including Love, the Company's VP of Medical Development

14 Luis Pena ("Pena ) and Deitcher. CW 1 said that, in 2004 or 2005, s/he discussed the potential for

15 the drug delivery system to disrupt the clot during quarterly company-wide meetings regularly held

16 after each Board ofDirectors meeting. As Love admitted in a December 11, 2006 conference call in

17 response to a question about the catheters breaking down clots in the placebo group, "it's always

18 been known that mechanical devices can work.

19 VI. CLINICAL TRIALS OF ALFIMEPRASE

20 38. Under the Federal Food, Drug, and Cosmetic Act, 21 U.S.C. §§301-97, new

21 pharmaceutical products cannot be marketed or sold in the United States unless the sponsor of the

22 drug demonstrates to the satisfaction of the FDA that the drug is safe and effective for each of its

23 intended uses. 21 U.S.C. §§355(a)&(d). The steps required before a drug may be marketed in the

24 U. S. include: (i) preclinical laboratory and animal tests; (ii) submission to the FDA of an application

25 for an Investigational New Drug ("IND ) exemption, which must become effective before human

26 clinical trials commence; (iii) human clinical trials to establish the safety and efficacy of the drug,

27 typically proceeding in three phases; (iv) submission of a detailed New Drug Application ("NDA )

28 or Product or Biologics License Application ("BLA ) to the FDA; and (v) FDA approval of the

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -12- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 16 of 79

1 NDA/BLA. The FDA does not approve a drug for treatment of a disease in general. Instead, a drug

2 is approved for treatment of a specific condition, or "indication, for which the drug has been tested

3 in patients. For each approved indication, the FDA will specify particular dosages and dosage

4 frequency determined to be safe and effective.

5 39. Success or failure of a clinical trial is determined by the ability ofthe trial to meet its

6 endpoints, including a demonstration that the results are statistically significant. "Statistically

7 significant means that a given result is unlikely to have occurred by random chance, or due to

8 factors outside ofthe control ofthe study. Statistical significance is measured on a scale of zero (0)

9 to one (1). A statistical significance level of 0.05 (5%) is the traditional scientific standard for

10 determining whether given results are statistically significant.3 Results are expressed as a "p-value,

11 which is a statistical measure of the probability that a difference between groups in a clinical trial

12 happened by chance. Statistical significance consisting of a p-value of less than 0.05 has

13 traditionally been considered convincing evidence by the FDA. A p-value of 0.05 means that there

14 is a 5 in 100 likelihood that the result occurred by chance. The lower the p-value, the more likely it

15 is that the difference between groups was caused by the drug, rather than by chance.

16 40. According to CW 1, the protocols for all of the clinical trials of alfimeprase were

17 written by Love, Dietcher and Pena.4 Pena had previously worked as a research associate at

18

19 3 Defendant Love stated on the December 11, 2006 conference call that "we had an agreement with the FDA that the P-value would be far lower than. 05 which would be the traditional number. 20 4 Clinical studies are accomplished pursuant to a protocol, which is a written submission to the 21 FDA as part ofthe IND. The protocol documents the manner ofdata analysis to be employed during the various phases oftesting, and is required to document the following factors: (a) a clear statement 22 of objectives and methods for final data analysis, including the establishment of "endpoints by which to measure the efficacy and safety ofthe drug; (b) a design that permits comparison ofthe test 23 group with a control group to quantitatively determine the study drug's effectiveness and safety; (c) procedures for selecting subjects that include methods for verifying that they have the condition 24 being studied; (d) a method of treatment assignment selected to minimize bias and assure comparability of subjects with respect to age, sex, severity and duration of disease, and uses of 25 concomitant therapy; (e) sufficient "blinding procedures (experimental design so that neither the doctor nor the patient is aware ofwhether the patient is receiving the experimental drug, a placebo or 26 a control) to minimize bias on the part of the subjects and investigation team; (f) outcome measures that are well-defined and reliable; and (g) an analysis chosen to determine an outcome that is 27 appropriate to the design. 28

1 Genentech, under Love's supervision. Despite his lack ofprior experience or an advanced medical

2 degree or doctorate, Pena was hired by Love to become Nuvelo's VP of Medical Development.

3 CW 1 characterized Pena as Love's "lackey. CW4 reported that data from the Phase 2 trials was

4 used while designing the Phase 3 trials. CW4 reported that Love and Deitcher were involved in

5 designing the Phase 3 protocols along with Company statistician Fong Wang-Clow ("Wang-Clow ).

6 According to CW3 and CW4, the Company encountered difficulties in designing the Phase 3

7 protocols, including from a statistical perspective. Both witnesses reported that the difficulties were

8 due in part to the involvement ofDeitcher who had little industry experience or experience designing

9 clinical trials. CW4 indicated that Deitcher and Wang-Clow had many disagreements over the

10 design of the Phase 3 protocols. CW4 stated that he/she was concerned with the low p-value

11 imposed by the FDA on the Phase 3 CO trial, and that during his/her tenure, the low p-value

12 imposed by the FDA on the Phase 3 CO trial was a topic of discussion with Deitcher and Wang-

13 Clow. CW 1 said that, approximately six to eight months before the completion of the Phase 2

14 clinical trials, Nuvelo formed an "alfimeprase team consisting of the people primarily responsible

15 for the investigational drug. The team included Love, Deitcher, Pena, and VP ofRegulatory Affairs

16 and Quality Assurance Brian Kersten. Pena was subsequently fired by Nuvelo in 2005 and replaced

17 on the team by Levy, VP of Research and Development.

18 1. PAO Clinical Program

19 41. Nuvelo's clinical trial program for PAO was known as "NAPA, which stood for

20 Novel Arterial Perfusion with Alfimeprase. PAO occurs when arterial blood supply to the

21 extremities is occluded by a clot, thus decreasing the flow of blood to some portion of the body,

22 commonly the lower limbs. Each year, more than 100,000 Americans suffer from PAO, also known

23 as leg attack. PAO is the result of underlying peripheral arterial disease ("PAD ), in which chronic

24 fatty plaque buildup restricts blood flow. The classic early symptom of PAO is leg pain or fatigue

25 during activity that subsides with rest. Continued restriction ofblood flow leads to pain at rest and,

26 if the condition continues, can lead to ulcers, gangrene, tissue death and if untreated, foot or leg

27 amputation.

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -14- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 18 of 79

1 42. Treatments for PAO include balloon angioplasty (with or without stents), open

2 vascular surgery, catheter based intervention and off-label use ofthrombolytic agents. The majority

3 ofpatients treated for PAO receive surgery, while less than half receive off-label thrombolytics for

4 24-36 hours, requiring an overnight stay in an intensive care unit in addition to an angiogram every

5 four hours to monitor the blood clot.

6 43. There are no FDA approved drugs specifically indicated for use in the treatment of

7 PAO. According to defendants, Nuvelo had the potential to capture up to half of the $400 million

8 market for treatment of PAO, because alfimeprase would provide a less-invasive and more cost-

9 effective alternative to surgery. During the Class Period, defendants were promoting alfimeprase as

10 a fast acting, safe drug therapy for PAO which, if approved by the FDA for PAO, would be the first

11 such approved therapy. However, as defendants well knew, during and prior to the Class Period,

12 several Genentech drugs were regularly being prescribed by physicians for "off-label treatment of

13 PAO, rendering the market opportunity of alfimeprase less clear than Nuvelo claimed.5

14 a. Phase 2 Study

15 44. Nuvelo's Phase 2 study of alfimeprase in PAO was a 24-center, 113 patient, open

16 label, randomized, dose escalation study evaluating the safety and efficacy of alfimeprase as a

17 treatment for acute PAO. Patients received 0.1 mg./kg., 0.3 mg./kg. or 0.6 mg./kg. of alfimeprase in

18 two separate 5-15 minute pulsed infusions administered via a side-hole catheter. The Phase 2 PAO

19 trial was a safety trial. The study's primary endpoint was safety, including major bleeding events, up

20 to 30 days after dosing. Secondary endpoints included open-surgery free survival at 14 and 30 days,

21 patency (restoration of blood flow), increase in ankle-brachial index and reduction in severity of

22 planned surgical interventions. There was no placebo arm in this study.

23 5 Use of an approved drug for any purpose other than those indications specifically approved 24 by the FDA is referred to as an "off-label use. Off-label uses include treating a condition not indicated on the label, treating the indicated condition at a different dosage or dosage frequency, or 25 treating a different patient population than those approved by the FDA. Under the Food and Drug Administration Modernization Act of 1997, if a manufacturer wished to market or promote an 26 approved drug for off-label uses, the manufacturer must comply with a set of stringent requirements prior to marketing including, submitting a supplemental application to the FDA demonstrating the 27 safety and effectiveness of the drug for treating the off-label use. 21 U.S.C. §§360aaa(b) and (c). 28

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -15- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 19 of 79

1 45. In September 2004, investigators presented the data from the study at the

2 Transcatheter Cardiovascular Therapeutics Scientific Symposium. The data which was presented

3 revealed thrombolysis (breaking up ofclots) rates ofup to 76% and restoration of arterial blood flow

4 (rates of up to 60%) were recorded within 4 hours of initiation of dosing. None of the 113 patients

5 suffered from intra cranial hemorrhage or death. Sixty-one percent (30/49) ofthe patients receiving

6 0.3 mg./kg. of alfimeprase avoided open vascular surgery for 30 days. Only one of seven major

7 bleeding events and three of nine minor bleeding events were deemed to be possibly related to

8 alfimeprase. However, there was no correlation between thrombolysis and restoration ofblood flow

9 on the one hand and avoidance of open surgery on the other hand. That is, the groups that had

10 higher rates of thrombolysis and restoration of blood flow also had higher rates of surgery. Also,

11 avoidance of surgery was not dose related; the rate of surgery increased with increased dose.

12 b. Phase 3 Studies

13 46. After the conclusion of the Phase 2 trial, Nuvelo started a Phase 3 program in April

14 2005 . The program consisted oftwo overlapping trials, NAPA-2 and NAPA-3, which were expected

15 to enroll a total of approximately 700 patients . According to CW3 and CW4, the Company

16 encountered difficulties in designating the Phase 3 protocols, including from a statistical perspective.

17 47. The first trial, NAPA-2, which opened in April 2005 , enrolled approximately 300

18 patients randomized to receive either 0.3 mg./kg. ofalfimeprase or placebo. Patients must have had

19 the onset of symptoms within 14 days of randomization. No plasminogen activators were allowed.

20 In contrast with the Phase 2 PAO study, the primary endpoint of NAPA-2 was avoidance of open

21 vascular surgery at 30 days. Enrollment was completed in September 2006. According to CW2,

22 Nuvelo had great difficulty enrolling patients for NAPA because the trials were randomized, double-

23 blind studies, meaning that neither patients nor their doctors would know whether they were being

24 treated with alfimeprase or a placebo. Most patients eligible for the study opted instead to receive

25 treatment with a Genentech thrombolytic drug that, while not approved by the FDA for treatment of

26 PAO, was regularly prescribed by physicians for that purpose because it had a 70% success rate in

27 busting the clot and avoiding risky surgery. As a result of the difficulties in enrolling patients, as

28 well as knowledge of the market and competition, Nuvelo and its employees involved in the

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -16- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 20 of 79

1 alfimeprase trials , including Love, knew that alfimeprase would face substantial competition from

2 such "off-label uses of drugs approved for other conditions.

3 48. On January 23, 2006, Nuvelo announced that the FDA had granted "fast track status

4 for the PAO program, which provides for accelerated regulatory filings and review.

5 49. Nuvelo announced the initiation ofNAPA-3, its second Phase 3 trial, in April 2006.

6 NAPA-3 was patterned after NAPA-2 and was subject to an SPA from the FDA.

7 2. CO Clinical Program

8 50. Nuvelo's clinical program for CO was known as SONOMA, which stood for Speedy

9 Opening ofNon-functional Occluded catheters with Mini-dose Alfimeprase. CO is the formation of

10 blood clots in patients with catheters. An estimated 5 million catheters are placed in patients in the

11 United States each year to deliver , nutritional support, antibiotics and blood products.

12 Occluded (blocked) catheters are a problem in about a quarter ofthe 5 million cases where catheters

13 are placed in patients each year. Occluded catheters are currently cleared using thrombolytic drugs,

14 such as Genentech's tPA, Activase (alteplase), which restores function to venous catheters in two to

15 four hours, or by more costly means, such as removing and replacing the catheter.

16 a. Phase 2 Study

17 51. In 2004, Nuvelo conducted a Phase 2, multi-center, randomized, double-blind study

18 ofpatients with occluded central venous catheters. The study compared three doses of alfimeprase

19 (0.3 mg., 1.0 mg. and 3.0 mg.) against Genentech's approved dose ofplasminogen activator Cathflo

20 Activase ("Cathflo ) (alteplase) (2.0 mg.). The study was to be conducted in up to 100 patients

21 across 32 centers in the United States.

22 52. On June 8, 2004, Nuvelo issued a press release announcing the "successful

23 completion of a planned interim analysis of its Phase 2 trial with its lead product candidate,

24 alfimeprase, for the potential treatment of venous catheter occlusion. The June 8th press release

25 stated that a planned interim analysis had been conducted on data from the first 48 patients enrolled

26 in the trial, and that, following review ofthe data for those patients, the Data Safety and Monitoring

27 Board and the Trial Operations Committee recommended that the trial continue to enroll in the two

28 highest dose groups, 1.0 mg and 3.0 mg, compared to the approved dose ofCathflo, thus eliminating

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -17- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 21 of 79

1 the lowest dose of 0.3 mg from further enrollment. The June 8th press release further stated that this

2 study had begun in June 2003, and "is being conducted in approximately 90 patients.

3 53. Approximately one month later, on July 12, 2004 Nuvelo issued a press release

4 announcing that "the Company has decided to close its Phase 2 alfimeprase trial in patients with

5 occluded central venous catheters sooner than expected in order to accelerate the program. The

6 Phase 2 trial concluded with 56 patients dosed. The July 12, 2004 press release further stated that a

7 Data Safety and Monitoring Board analysis indicated that there were no safety concerns in any ofthe

8 alfimeprase dose groups, and quoted the statement of the Company's VP of Medical Affairs

9 Deitcher, that "We believe this data is more than sufficient to guide our continuing development

10 efforts. The July 12th press release also revealed that the "study was designed to treat up to 100

11 patients....

12 54. In early December 2004, data for the 55 patients enrolled in the Company's Phase 2

13 clinical trial of alfimeprase for use in restoration of function in catheter occlusion were reported in a

14 December 6, 2004 Nuvelo press release, presented by Deitcher at the Annual Meeting and

15 Exposition of the American Society of Hematology, and posted on the Company's website. The

16 December 6, 2004 press release reported that the 3.0 mg alfimeprase dose produced cumulative flow

17 (patency) rates of 50% at 15 minutes after the first dose, 60% at 120 minutes after the first dose, and

18 80% at 120 minutes after the second dose. In contrast, Cathflo produced patency rates of 0% at 15

19 minutes after the first dose, 46% at 120 minutes after the first dose, and 62% at 120 minutes after the

20 second dose. According to the December 6th press release there were no major hemorrhagic events

21 in any treated patients. In addition, that press release noted that "[w]hen a catheter becomes

22 occluded, the ultimate goal is to restore patency (i.e., flow) in a timely and cost effective manner

23 with minimal risk to the patient.

24 b. Phase 3 Studies

25 55. In May 2005 , Nuvelo announced its Phase 3 clinical trial program for CO. Nuvelo

26 conducted two Phase 3 trials : SONOMA-2 and SONOMA-3. According to CW3 and CW4, the

27 Company encountered difficulties in designating the Phase 3 protocols, including from a statistical

28 perspective.

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -18- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 22 of 79

1 56. The first trial, SONOMA-2, enrolled its first patients in September 2005 and

2 completed enrollment in September 2006. SONOMA-2 was a randomized, double-blind, 300 patient

3 trial, comparing 3 mg. alfimeprase against placebo as a treatment for patients with occluded central

4 venous catheters. Two-thirds of the 300 patients received alfimeprase and the remainder received

5 placebo. The primary endpoint ofthe SONOMA-2 trial was the restoration of function to occluded

6 central venous catheters at 15 minutes, i. e., the success ofthe trial was to be judged by the statistical

7 difference in the restoration of function between the alfimeprase group and the placebo group.

8 57. The second trial, SONOMA-3, began enrollment in February 2006 and was designed

9 as an open-label, single-arm trial evaluating the safety of alfimeprase in 800 patients.

10 58. Investors reasonably understood and expected that Nuvelo would have to demonstrate

11 statistical significance to a p-value of 0.05. On December 11, 2006, defendants admitted that the

12 results of SONOMA-2 did not meet the extraordinarily high threshold for regulatory approval

13 required by the FDA for the Nuvelo trial. Love admitted that "we had an agreement with the FDA

14 that the p-value would be far lower than 0.05 which would be the traditional number.

15 Subsequently, on June 26, 2007, Nuvelo admitted that thep-value requirementfor SONOMA-2 was

16 less than 0.00125:

17 Data from the first Phase 3 trial in the CO program, SONOMA-2, showed that alfimeprase restored catheter function in patients with 18 occluded catheters within 15 minutes with a p-value of 0.022. It did not, however, meet the more stringentp-value requiredfor a single 19 pivotal trial, less than 0.00125, nor did it meet the company 's target productprofilefor commercial success.6 20 59. A p-value of 0.00125 is extraordinarily low, and is virtually unheard of in the 21 industry, as it is exceedingly difficult to meet. Plaintiffs have been unable to identify even one 22 example of another FDA drug trial that was required to meet such a low p-value. 23 3. Nuvelo Announces Failure of Both PAO and CO Phase 3 Trials 24 60. Before the opening of trading on December 11, 2006, Nuvelo and Bayer 25 unexpectedly issued a press release announcing the failure of both the PAO and CO Phase 3 trials. 26

27 6 Emphasis added unless otherwise noted. 28

(Nasdaq: NUVO) and Bayer HealthCare today announced top-line data demonstrating that the Phase 3 clinical trial 5 of alfimeprase in acute peripheral arterial occlusion (PAO), known as NAPA-2 (Novel Arterial Perfusion with Alfimeprase-2), did not meet 6 its primary endpoint of avoidance ofopen vascular surgery within 30 days of treatment . The companies also announced that the Phase 3 7 trial in catheter occlusion (CO), known as SONOMA-2 (Speedy Opening of Non-functional and Occluded catheters with Mini-dose 8 Alfimeprase - 2), did not meet the endpoint of restoration of function at 15 minutes. These trials did not meet key secondary endpoints. In 9 addition, the companies announced that they have temporarily suspended enrollment in the ongoing Phase 3 trials , NAPA-3 and 10 SONOMA-3, until further analyses and discussions with outside experts and regulatory agencies are completed. 11 These data will be submitted for presentation at the next 12 appropriate medical meetings.

13 `These outcomes are disappointing particularly for patients with acute PAO, who have few treatment options,' said Dr. Ted W. Love, 14 chairman and chief executive officer ofNuvelo. `We and our partner Bayer will conduct further analyses and have discussions with the 15 Data Safety and Monitoring Board members, outside experts and regulatory authorities to determine how to proceed with the 16 development of alfimeprase, including the possibility of alternative dosing and delivery.' 17 61. During a December 11, 2006 conference call following the announcement, Love 18 explained that in the PAO trial, although alfimeprase dissolved some clots, the drug failed to perform 19 significantly better than the placebo because a substantial number ofclots had not been dissolved by 20 the drug, but had instead been broken up by the insertion of a catheter into the clot in patients who 21 received a placebo. When pressed, Love and Levy admitted that since none ofthe Company's prior 22 clinical testing had included the use of a placebo, any past instances ofalfimeprase "dissolving blood 23 clots was more likely than not simply attributable to the clots being broken up by the insertion of a 24 catheter directly into the clots - rather than any "dissolving effect the drug had. Additionally, 25 defendants admitted that even if they could increase the dosage of alfimeprase to increase its 26 thrombolytic clot busting effect for PAO, it could likely be prohibitively unsafe to do so, as there 27 was an increased incidence of bleeding in patients with alfimeprase as compared to the placebo. 28

1 62. During the conference call, Love was specifically questioned on whether insertion of

2 the catheter had an effect on the Phase 2 trial - and he was forced to admit it had:

3 Jim Birchenough [Lehman Brothers analyst]: So I'm just trying to understand why that might not have happened in the Phase II 4 experience where it seems that you had higher thrombolysis rates?

5 Dr. Ted W. Love: ... I actually think it did probably happen in Phase H. 6 63. In addition, Love admitted in the conference call that the CO trial also faced far 7 greater risks than previously revealed: 8 While the data from the SONOMA-2 trial show a statistically 9 significant difference in the rate at which alfimeprase and placebo dissolved clots in venous catheters at 15 minutes, this result did not 10 meet the high threshold established by the FDA for regulatory approval based on only one control trial. 11

12 [WJe had an agreement with the FDA that the P-value would befar 13 lower than .05 would be the traditional number. We were below that number. 14 64. Nuvelo has yet to publish data regarding the conduct or results ofthe Phase 3 trials in 15 any medical journal, which has caused some members of the scientific community to question 16 Nuvelo's scientific integrity.? As CW2 stated, it is "ridiculous, and "non-scientific not to publish 17 results from clinical trials, whether or not the results were positive. In addition, Nuvelo has 18 contacted numerous potential witnesses in this action, encouraging them not to discuss anything 19 related to the Phase 3 clinical trials of alfimeprase with plaintiffs or their investigators. This 20 conduct, designed to conceal the full extent of defendants' misconduct, contrasts starkly with the 21 Company's rush to disclose favorable trial results when it was raising money from the public. 22 65. On June 26, 2007, Nuvelo conducted another conference call following the 23 announcement that Bayer, like Amgen before it, had pulled the plug from further efforts to 24 commercialize alfimeprase. During that call, defendant Levy revealed that, in addition to an 25

26 7 On November 7, 2007, Nuvelo announced that data from the Phase 3 CO trial will be presented at a meeting in Atlanta next month, a year after the results of the failed trial were 27 announced. 28

extremely stringent p-value, alfimeprase also hadfailed to meet itspreviously undisclosed "target

2 profile," thus rendering it unmarketablefor CO:

3 [Levy] : The second indication we are pursuing is catheter occlusion. Data from the first Phase 3 trial from this program, SONOMA-2 4 showed that while Alfimeprase restored catheter function in patients with occluded catheters within 15 minutes with a p-value of .022, it 5 did not meet the more stringent p-value required for a single pivotal trial of less than . 00125. 6 While the p-value achieved in SONOMA-2 accompanied by a second 7 controlled trial with comparable results could potentially support registration, it likely would not meet the target product profile we 8 believe necessary for commercial success in the marketplace. Accordingly, we have decided to investigate whether a single, higher, 9 more concentrated dose of Alfimeprase would generate results more consistent with the desired target product profile for this indication. 10 66. In an August 1, 2007 conference call with analysts, Levy provided further insight on 11 the undisclosed "product profile : 12 [Analyst] William Ho: ... And why do you think the catheter 13 occlusion will work just at the higher doses?

14 Dr. Michael Levy: Well, I think it's important to recognize that on some level, catheter occlusion did work in the preceding Phase 3 trial. 15 It worked to the extent that we were able to confirm it was an active thrombolytic . It worked to the extent that we were able to get a p- 16 value better than . 05, which is the standard test for scientific significance. 17 But what it didn't do was at the p-value that we set for regulatory 18 approval with a single trial and it didn 't hit the targetproductprofile that we were looking for to be successful in this marketplace. 19 Clearly, the marketplace today is only around $100 million and to be successful, you really have to have a very goodproductprofile. 20 67. On August 22, 2007, the Company announced that it was re-initiating the SONOMA- 21 3 trial of alfimeprase in patients with CO. The revised trial was designed to determine whether a 22 single, higher, more concentrated dose of alfimeprase could restore function to blocked central 23 venous catheters within 15 minutes. On the news, Nuvelo's shares rose 26 cents or 16 %, to $1.89 in 24 afternoon trading. Brean Murray Carret & Co. ("Brean Murray) analyst Jonathan Aschoff 25 ("Aschoff ) upgraded the stock to "Hold from "Sell and removed his target price of $2 per share. 26 However, Aschoff wrote that the past trial results show the drug will not succeed: "We view the 27

1 alfimeprase program mostly as terminal, given that the drug failed to deliver on either its primary

2 or any key secondary endpoints in either the NAPA-2 or SONOMA-2 Phase 3 trials ....

3 VII. DEFENDANTS' SCHEME TO DEFRAUD

4 A. Defendants Falsely Represented the Significance and Reliability of the Phase 2 Alfimeprase Trial Data, and Conceal Material Risks to FDA 5 Approval and Commercial Marketability for PAO and CO.

6 68. Throughout the Class Period, Nuvelo and its top officers repeatedly claimed that the

7 Phase 2 trials had demonstrated alfimeprase's ability to dissolve clots in patients with acute PAO,

8 and cleared blocked catheters much more quickly than existing treatments. Simultaneously,

9 defendants proclaimed that the Phase 3 PAO and CO trials represented a "low risk path to FDA

10 approval with a "high probability of success. At the same time, however, defendants failed to

11 specifically disclose the significant risks that affected the then-ongoing Phase 3 trials, including

12 known limitations of the Phase 2 trials. Together, these statements and omissions misled investors

13 both about the quality and reliability of the Phase 2 data and the existing risks to success in the

14 ongoing Phase 3 trials.

15 69. Investors had repeatedly been reassured ofthe efficacy ofalfimeprase as compared to

16 a placebo. For example, a May 2, 2005 statement at the Company' s earnings conference, that would

17 be reconfirmed repeatedly throughout the Class Period, claimed that the Company had "power

18 calculations that clearly established the efficacy of alfimeprase as compared to a placebo.

19 Defendants failed to disclose that the "power calculations were based upon placebo assumptions

20 which had no reasonable basis in fact because defendants did not know how many patients avoided

21 open surgery for 30 days as a result of the catheter insertion breaking up the clot. Defendant Levy

22 falsely claimed that the numbers in the Phase 3 trial are driven by "the need to put in place a good

23 size safety database rather the need to confirm the efficacy of this drug, which we are all very

24 bullish on obviously.

25 70. Nuvelo never disclosed any of the specific risks that rendered success in the Phase 3

26 trials much less likely than represented. Rather, Nuvelo's periodic reports filed with the SEC during

27 (and prior to) the Class Period contained only general and generic risk warnings, such as "Our near-

28 term success is dependent on the success of our lead product candidate, alfimeprase, and we cannot

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -23- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 27 of 79

be certain that it will receive regulatory approval or be successfully commercialized, and "We face

2 heavy government regulation, and FDA and international regulatory approval of our products is

3 uncertain. However, the reports did not contain any specific risk warnings regarding the Phase 2

4 trials, the possibility that the results ofthose trials were caused by the catheter being pushed through

5 a blood clot, the extraordinary statistical significance barrier imposed on the SONOMA Phase 3 trial,

6 or that the Company had an undisclosed target product profile which was necessary to meet in order

7 to market the drug for CO.

8 71. Rather, Love and Levy frequently told investors that Nuvelo was starting with PAO

9 and CO because it provided a "low risk path to regulatory approval or a "rapid & low risk entry

10 strategy with a "high probability of success. In addition, defendants represented that following

11 approval ofthe PAO and CO indications, Nuvelo claimed it would be able to use alfimeprase to treat

12 victims and patients suffering with deep vein , both potentially huge markets. This

13 theme would be repeated throughout the Class Period. In a presentation to investors, for example,

14 Nuvelo graphically illustrated its claims that its "low risk entry strategy with a "high probability of

15 success would lead to enormous revenue growth:

26 72. On January 5, 2006, the first day of the Class Period, Nuvelo announced it had

27 entered into a new financial alliance - this time with Bayer. The Bayer deal provided a $50 million

28 upfront payment to Nuvelo and included up to $385 million in additional fees and payments. The

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -24- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 28 of 79

1 Company's stock price surged on the January 5, 2006 announcement, increasing 41%, its largest

2 increase in six years on extremely high volume. During a conference call that day, Love claimed

3 PAO and CO were just "the tip of the iceberg for the drug:

4 Cory Kasimov, Analyst, Oppenheimer & Co: ... You have long talked about the potential market opportunity for Alfimeprase and the number you've consistently 5 thrown out there is greater than $500 million in worldwide market potential. How does that change now with the confirmation that you will indeed be taking 6 Alfimeprase into the clinic to evaluate it against both stroke and DVT?8

7 Dr. Ted Love: The number certainly goes up quite dramatically. The $500 million number that you reference is in fact an accurate number. We built that number off 8 looking at two indications. And with the two indications that we had under study, that is acute PAO and catheter occlusion. It has been very clear to us from the very 9 beginning that stroke and DVT are much larger market opportunities. But we did not start with those indications because ofthe development strategy was reallyfocused 10 on going after indications which will be rapid to market, which would demonstrate the superior advantage of the compound in terms of its fast speed of action and 11 wouldprovide a low-risk regulatory path for approval Now that we've got those programs obviously well underway, we plan to turn our attention to DVT, stroke, 12 other indications to really exploit the full commercial potential and the full medical benefit of the product. 13 73. Market analysts and investors reasonably understood Nuvelo's deal with Bayer as an 14 endorsement of alfimeprase. In a January 5, 2006 Company Alert, Deutsche Bank Securities Inc. 15 ("Deutsche Bank ) analyst Jennifer Chao ("Chao ) reported, "In our view, this collaboration 16 significantly validates the science and clinical/regulatory strategy for alfimeprase as a potential 17 blockbuster thrombolytic. Similarly, Prudential Equity Group, LLC ("Prudential ) analyst Jason 18 Zhang ("Zhang ) reported, "We are encouraged by the timing of this partnership announcement as 19 we think that it validates the [alfimeprase's] potential, even in its pre-approval stage of 20 development. Oppenheimer & Co., Inc. ("Oppenheimer ) even raised the profile ofNuvelo's stock 21 based on the Bayer agreement: "Based on Bayer agreement, we are increasing our 12-month target 22 price to $18 from $13. 23 74. That same day, CIBC World Markets analysts stated in a report upgrading Nuvelo to 24 "Sector Outperformer : "We believe the partnership provides substantial validation for the safety, 25 efficacy, and market potential of alfimeprase. Unaware of the stringent p-value requirement 26

27 8 DVT refers to deep venous thrombosis. 28

1 imposed on the Phase 3 CO data by the FDA or that the Phase 3 PAO trial was at risk of failing

2 because positive results were simply caused by the breaking up of clots by a catheter, the analysts

3 wrote in the same report with respect to the Phase 3 CO program: "Based on the phase II data, we

4 believe the phase III catheter occlusion program has a high chance of success.... The phase II data

5 . showed strongly superior efficacy at 15 minutes to alteplase ... at all tested doses. The analysts

6 further noted that "alfimeprase is likely to succeed in ph.III studies for PAO and CO, and

7 specifically regarding trials for PAO, "We believe the study is substantially overpowered and has a

8 high probability of success.

9 75. On January 23, 2006, the Company announced it had been granted FDA "Fast Track

10 Status for alfimeprase. Love stated that "Fast track designation represent[ed] a further step in the

11 achievement of [the Company's] regulatory strategy .... Again, unaware of the stringent

12 requirements placed on the alfimeprase development program by the FDA and other undisclosed

13 risks to FDA approval, the market reacted favorably to Love's announcement. CIBC World Markets

14 analysts noted that "[f]ast track status will allow NUVO to submit a `rolling' NDA for alfimeprase

15 and may signal a willingness by the FDA to consider accelerated review. Furthermore "while the

16 receipt of Fast Track designation for alifineprase (sic) in PAO is not surprising, we believe it is

17 positive and may provide a shorter course to market for alfimeprase. We believe ph.III trials of

18 alfimeprase in PAO and CO are likely to succeed and expect the stock to appreciate into ph. III data.

19 76. On January 24, 2006 the Company again used apparently good news to tap the

20 financial markets, announcing it would conduct a Follow-On Offering of 5.5 million shares

21 underwritten by JP Morgan, Lehman Brothers, Inc. and Deutsche Bank. On January 31, 2006, the

22 Company issued and sold approximately 7.5 million shares of its common stock at $16 per share in

23 the offering, receiving over $119 million in proceeds.

24 77. On February 27, 2006, the Company announced that it had begun patient enrollment

25 in SONOMA-3, a second pivotal study of alfimeprase for the treatment of CO. On this and other

26 positive statements made by defendants, analysts such as Caroline Stewart at Morgan Joseph &

27 Company Inc. ("Morgan Joseph ) increased their price targets by 56% - from $16 to $25 per share.

28

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -26- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 30 of 79

1 In a February 28, 2006 report, Deutsche Bank analyst Chao similarly raised the price target for

2 Nuvelo stock from $18 to $24.

3 78. In a CIBC World Markets analyst report dated February 28, 2006, the analysts,

4 unaware that the p-value requirement for SONOMA-2 (Phase 3 trial for CO) was less than 0.00125,

5 which was forty times less than the p-value typically imposed by the FDA or that the NAPA trials

6 for PAO were at risk of failing because positive results were simply caused by the insertion of a

7 catheter into a blood clot, reiterated their January 5, 2006 positive outlook: "Alfimeprase is likely to

8 be effective in PAO and CO. Regarding the Phase 3 trial for PAO, the analysts repeated, "We

9 believe the study is substantially overpowered and has a high probability of success. And with

10 respect to CO, the analysts wrote: "The phase II data in this indication demonstrated strongly

11 superior efficacy at 15 minutes to alteplase ... at all tested doses, and based on this data we believe

12 the phase III program has a high probability of success.

13 79. Nuvelo announced that it had begun patient enrollment in a second Phase 3 trial of

14 alfimeprase for PAO - NAPA-3 - on April 10, 2006, again reiterating that the Phase 2 PAO trial

15 purportedly showed that alfimeprase "can restore arterial blood flow within four hours of initiation

16 of dosing [and] has a favorable safety profile with minimal bleeding complications.... These

17 statements were repeated again on May 5, 2006, when Nuvelo announced first quarter 2006 financial

18 results. That same day, still unaware of the undisclosed risks to FDA approval, Oppenheimer

19 analysts wrote, "Based primarily on Phase II trial results, we have a high conviction level that both

20 studies [NAPA-2 and SONOMA-2] will be successful. Similar sentiments were reflected in a June

21 19, 2006 Needham & Company, LLC ("Needham ) report following the Company's analyst day,

22 which stated: "[W]e believe that prior clinical trials have demonstrated that alfimeprase is an

23 effective clot buster.

24 80. On July 6, 2006, the Company announced the publication ofPhase 2 alfimeprase trial

25 results in CO in the July 1, 2006 issue of the Journal of Clinical Oncology. In the press release,

26 Nuvelo stated that the results "demonstrat[e] that alfimeprase can quickly restore function to

27 occluded central venous access devices (CVADs). Love stated: "Based on these promising Phase 2

28 results, we have initiated two overlapping, multi-national Phase 3 trials evaluating the 3 mg dose of

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -27- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 31 of 79

1 alfimeprase in catheter occlusion. We anticipate data from the first of these trials, the SONOMA-2

2 trial, in the second half ofthis year, and hope to confirm the ability ofalfimeprase to restore function

3 to occluded catheters in 15 minutes or less. In a Company Alert issued that same day, Deutsche

4 Bank repeated the Company's announcement that the results showed "that alfimeprase can restore

5 function to occluded central venous access devices (CVADs), and reiterated its "Buy

6 recommendation.

7 81. On August 3, 2006, Nuvelo announced second quarter 2006 financial results, again

8 taking the opportunity to tout alfimeprase's Phase 2 results. Following Nuvelo's conference call

9 announcing the results, on August 4, 2006, Brean Murray, unaware ofthe undisclosed risks to FDA

10 approval, reported, "During the Q&A session of the conference call, Nuvelo indicated that in the

11 NAPA-2 trial, alfimeprase was working well in large and small clots, as well as in old and new

12 clots. Similarly, in a CIBC World Markets analyst report of the same day, the analysts, remaining

13 in the dark, reiterated their belief that "alfimeprase has a high probability of success in PAO and

14 CO. Regarding the Phase 3 trial for PAO, the analysts repeated, "We believe the study is

15 substantially overpowered and has a high probability of success. With respect to CO, the analysts

16 wrote: "The recently published phase II data for alfimeprase in this indication demonstrated superior

17 efficacy at 15 minutes to alteplase at all tested doses.... Based on this data we believe the phase III

18 program has a high probability of success.

19 82. By late summer, more analysts had initiated coverage of Nuvelo due to the

20 significance of alfimeprase. Miller Johnson Steichen Kinnard Investment Securities ("Miller

21 Johnson ) initiated coverage ofNuvelo in an August 23, 2006 analyst report in which it noted that

22 for both PAO and CO, alfimeprase "has potential to emerge as the standard of care, addressing peak

23 market sales potential in excess of $500MM. Similarly, a September 12, 2006 Wachovia Capital

24 Markets, LLC ("Wachovia ) report initiating coverage of Nuvelo touted the Phase II results of

25 alfimeprase for both the PAO and CO indications: "Relatively simple path to approval: Data from a

26 Phase II trial evaluating alfimeprase efficacy and safety in 113 patients with peripheral arterial

27 occlusion (PAO) supports the likelihood of a positive Phase III outcome for this niche indication and

28 a relatively simple means to market, in our view. Phase II data in catheter occlusion (CO) also

1 confirms activity with top-line Phase III results from both indications potentially ready for release in

2 Q4 2006. The report further noted as its investment summary: "alfimeprase is well positioned to

3 become the standard of care for treating all blood clot disorders ....

4 83. The pattern repeated itself again when Nuvelo announced its third quarter 2006

5 financial results on November 2, 2006, again misrepresenting alfimeprase's Phase 2 results and

6 Phase 3 prospects. Still, unaware of the undisclosed risks, analysts, like Oppenheimer, maintained

7 "a high level of conviction for a successful outcome for [NAPA-2 and SONOMA-2].

8 B. Defendants' Scheme Unravels.

9 84. Prior to the start of trading on December 11, 2006, the investment community was

10 shocked when Bayer announced that alfimeprase had completely failed to meet the primary

11 endpoints in the clinical trials for both PAO and CO. The primary endpoint for the PAO trial was

12 preventing patients with blood clots in their legs from needing surgery within 30 days of taking the

13 drug. The trial failed to reach it. The primary endpoint for the CO treatment study was the ability to

14 unblock catheters within 15 minutes of taking the drug, demonstrated to a p-value of 0.00125. The

15 trial failed to reach it. The clinical trials also failed to reach any of their key secondary endpoints.

16 Supra, ¶110, 47, 56, 60-63.

17 85. In reaction to the news ofthe failure ofthe NAPA-2 and SONOMA-2 trials before the

18 market opened on December 11, 2006, the price ofNuvelo shares plunged 80%, to their lowest level

19 in over three and a half years , making Nuvelo the biggest percentage decliner on the NASDAQ

20 composite . Nuvelo's stock closed at $4.05 a share, down $15 . 50 a share in unusually heavy trading

21 of 90 million shares , more than 176 times the average daily trading volume. Nuvelo's stock had

22 been trading an average of 450,000 shares a day in recent weeks . At one point, the stock fell as low

23 as $3.35 , its worst performance since April 2003 , prompting an immediate chorus ofnegative analyst

24 comments including downgrades. Nuvelo's options became worthless.

25 86. For example, UBS Investment Research ("UBS ) analyst Maged Shenouda

26 downgraded Nuvelo to "Reduce from "Buy. The Company's target price went to $3 from $28.

27 Shenouda said Bayer is likely to exit the collaboration in the first quarter of 2007. At Oppenheimer,

28 analyst Cory Kasimov ("Kasimov ) downgraded the Company to "Neutral from "Buy and

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -29- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 33 of 79

1 removed his $24 price target. Kasimov added that the rest of the Company's pipeline is high risk

2 and at an early stage of development, and that there is concern that Bayer could potentially walk

3 away from the alfimeprase partnership. Wachovia analyst George Farmer cut his rating to market

4 perform from outperform, saying he saw only "modest value in the remainder ofNuvelo's pipeline.

5 He valued the stock between $3 and $5. JP Morgan downgraded the stock to neutral from

6 overweight, explaining that alfimeprase had been a key driver in Nuvelo's investment value - and

7 valued the Company at the $3 per share cash it had on its books.

8 87. In a December 11, 2006 Prudential report, analyst Zhang wrote:

9 Sometimes, when a stock is hammered badly after failure of a key clinical trial, it could be a good buying opportunity if the trial could be salvaged or if the drug is in 10 other clinical trials that could yield positive data to support further development or approval. We believe that is not the case here. Alfimeprase is the main drug from 11 Nuvelo's pipeline and represents more than 80% ofthe company's value. Without a reasonable expectation this drug would be approved for the two indications the 12 company sought, the stock is unlikely to recover anytime soon.

13 88. Also, on December 11, 2006, analysts Kasimov and Sa'ar Yaniv, of Oppenheimer

14 issued an analyst report entitled "Downgrading to Neutral on Alf Failure stating:

15 Is alfimeprase dead ? On the heels of these results, enrollment has been suspended in the Phase III NAPA-3 study in PAO (- 100 pts enrolled to date) and SONOMA-3 16 study in CO (-250 pts enrolled to date). Planned Phase II trials in stroke and DVT have also been postponed. Additionally, we are concerned that Bayer (BAY, $52.48, 17 Not Covered) could potentially walk away from the alfimeprase partnership.

18 What else does NUVO have? Aside from alfimeprase, the rest ofNUVO' s pipeline is early and high risk.... 19 89. On June 26, 2007, Nuvelo announced Bayer had terminated its partnership with 20 Nuvelo. In response to the Company's announcement, analysts expressed further pessimism about 21 alfimeprase and on June 26, 2007, shares of Nuvelo fell $0.74, or 22%, to $2.60 in after hours 22 trading, after falling $0.01 to close at $3.34. On June 27, 2007 Brean Murray analyst Aschoffwrote 23 that the Bayer partnership was critical to Nuvelo's cash flow and reiterated a $2 price target: "We are 24 uncertain as to how and why Nuvelo will fund the development of Alfimeprase, considering it has 25 already failed to meet its primary endpoint in two Phase 3 trials. Banc of America Securities LLC 26 ("Banc of America ) analyst William Ho, maintaining a "Neutral rating and a $3.50 target price, 27 said there was little chance the drug will succeed in new trials. 28

1 90. On August 1, 2007, Nuvelo announced that it was terminating employees to reduce its

2 workforce by approximately 30% and realigning its organization to focus on core development

3 programs that it believes will produce nearest-term proof of concept data. As a result of the

4 reduction in workforce, effective August 3, 2007, the Company stated that it expected to have less

5 than 80 employees, a reduction of 45% from 2006, and expected this realignment of personnel and

6 programs to result in reduced annual expenses of about $15 million from current levels. As part of

7 the reorganization, H. Ward Wolff, Senior VP and CFO left the Company effective August 14, 2007.

8 VIII. FALSE AND MISLEADING STATEMENTS DURING THE CLASS PERIOD 9 91. Throughout the Class Period, defendants mischaracterized the results ofthe Phase 2 10 trials of alfimeprase for CO and PAO and the design and parameters of the Phase 3 trials and 11 misrepresented the risks associated with approval of alfimeprase for treatment of CO and PAO. 12 Each defendant is liable for (i) making false statements and/or (ii) failing to disclose adverse facts 13 known to him about Nuvelo. Defendants ' fraudulent scheme and course ofbusiness that operated as 14 a fraud or deceit on purchasers of Nuvelo securities was a success, as it: (i) deceived the investing 15 public regarding Nuvelo's prospects and business, and specifically the prospects for the Company's 16 leading drug candidate , alfimeprase; (ii) artificially inflated the prices of Nuvelo securities; (iii) 17 allowed defendants to arrange to sell and actually sell $ 119 million worth of Nuvelo securities at 18 artificially inflated prices in the Follow-On Offering; (iv) allowed defendants to draw huge salaries 19 and obtain large bonuses which were directly tied to the Company' s financial success ; (v) permitted 20 defendant Titus to sell $ 1.5 million worth of Nuvelo stock at inflated prices; and: (vi) caused 21 plaintiffs and other members ofthe Class to purchase Nuvelo's publicly traded securities at inflated 22 prices. 23 A. Defendants' January 5, 2006 False and Misleading Statements 24 92. Before the opening oftrading on January 5, 2006, Nuvelo and Bayer issued a release 25 entitled "Nuvelo and Bayer HealthCare Enter Comprehensive Collaboration Agreement to Maximize 26 Global Development and Commercialization of Alfimeprase, which stated in relevant part: 27 Nuvelo, Inc. (Nasdaq: NUVO) today announced that it has 28 entered into a collaboration agreement with Bayer HealthCare AG

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ - 31 - C se 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 35 of 79

1 (BHC) to maximize the global development and commercialization of alfimeprase, Nuvelo's lead Phase 3 product candidate. Alfimeprase, 2 a novel, first-in-class thrombolytic or blood clot dissolver that directly degrades fibrin, has been shown in clinical studies to 3 provide rapid clot dissolution with a well tolerated safety profile.

4 93. Also on January 5, 2006, Nuvelo conducted a conference call with analysts to discuss

5 the Bayer deal. Defendants Love, Titus and Levy each participated in and spoke on behalf of

6 Nuvelo during the call. At the outset of the call, Love repeated the information contained in the

7 press release, and also claimed that alfimeprase "has blockbuster potential that could become a

8 "transformational therapy, much like serotonin reuptake inhibitors were in Depression, a reference

9 to one of the biggest-selling class of drugs on the market:

10 [E]veryone that came in the door quite frankly was consistently impressed with the data that we generated with Alfcmeprase, 11 suggesting a dramaticfeat ofaction and also its safety profile which emanates from the inactivation by alpha-2 macroglobulin. And it is 12 really that profile and the confidence that that profile will be demonstrated in Phase III that generated excitement at Bayer and 13 generated excitement quite frankly in every organization that we spoke with. ... So I think it really is looking forward recognizing that 14 there are a great deal of thromboembolic disease out there, probably 10 million patients worldwide that really are not being well served 15 with current therapies and Alfimeprase could deliver that unmet medical need. 16 94. Defendant Love explained that Nuvelo started with the PAO and CO indications 17 because they would provide a "low-risk regulatorypathfor approval, from which defendants could 18 expand alfimeprase to the much larger markets for stroke and DVT: 19 It has been very clear to us from the very beginning that stroke and 20 DVT are much larger market opportunities. But we did notstart with those indications because of the development strategy was really 21 focused on going after indications which will be rapid to market, which would demonstrate the superior advantage ofthe compound 22 in terms of its fast speed of action and would provide a low-risk regulatory path for approval Now that we've got those programs 23 obviously well underway, we plan to turn our attention to DVT, stroke, [and] other indications to really exploit the full commercial 24 potential and the full medical benefit of the product.

25 1. Reasons Why Defendants' January 5, 2006 Statements Were False and Misleading 26 95. The statements in the January 5, 2006 press release and conference call that 27 alfimeprase "has been shown in clinical studies to provide rapid clot dissolution, that the Phase 2 28

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -32- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 36 of 79

1 data "suggest[s] a dramatic feat of action and "fast speed of action that "will be demonstrated in

2 Phase 3, that the Phase 3 trials therefore represented a "low risk regulatory path for approval, and

3 that alfimeprase "has blockbuster potential and "will be rapid to market for PAO and CO, were

4 false because the Phase 2 data was not as reliable or significant as defendants had led the market to

5 believe, nor were the existing risks to FDA Approval or commercial marketability ofalfimeprase for

6 PAO and CO fully disclosed.

7 96. As alleged previously, defendants knew that blood flow in some patients enrolled in

8 the NAPA PAO trials would be restored simply by inserting the catheter into the clot to deliver the

9 drug, rather than through any action of alfimeprase, and had no basis for representing to the market

10 the degree to which the drug caused the purportedly successful Phase 2 results. Based on the small

11 size of the CO Phase 2 trial, preclinical studies which showed greater efficacy at higher doses and

12 the lower than expected rate of catheter clearance in the comparator alteplase arm, defendants also

13 had no reasonable basis for predicting success in the Phase 3 trials for CO, because they did not

14 know whether the dose of alfimeprase chosen for the study in SONOMA-2 would yield the required

15 results or would be appropriate for the commercial success of alfimeprase in this indication. As a

16 result, the regulatory path for approval for CO was far from "low risk, nor was there a "high

17 probability of success in the Phase 3 PAO and CO trials, as defendants had previously represented.

18 97. These statements, together with defendants' other statements regarding the purported

19 success of the Phase 2 trials and the likelihood of success in the Phase 3 trials as elsewhere alleged,

20 were also materially false and misleading to investors because Nuvelo omitted to disclose, in the

21 press release, on the conference call, or elsewhere, known risks that reduced the likelihood that the

22 Phase 2 results could be replicated in Phase 3 trials, that the Phase 3 trials would succeed or that the

23 drug would be marketable, including that: (i) in the Phase 2 PAO trial the clot may have simply been

24 broken up by the action of the catheter pushing into the clot, rather than dissolved by the action of

25 the drug, a possibility that had been raised internally at Nuvelo even before the Phase 2 PAO trials

26 were completed; (ii) in the Phase 3 CO trial, Nuvelo had agreed with the FDA to demonstrate

27 success at a statistical significance level that was forty times more stringent than what the market

28 believed, rendering success much less likely; (iii) the market opportunity for the drug in PAO was

1 much smaller than represented to analysts and the market because of competition from off-label use

2 of other drugs and mechanical clot-busting techniques, the potential impact ofwhich was not timely

3 or accurately disclosed to investors; (iv) Nuvelo had an undisclosed "target product profile which

4 would be necessary to meet in order for the Company to market alfimeprase for CO, and the

5 Company would not proceed to market alfimeprase for that indication ifthe trial results did not meet

6 that profile, even if the drug was otherwise qualified for FDA approval.

8 98. The following facts, as alleged in more detail elsewhere in the Complaint, give rise to

9 a cogent inference which is stronger than any non-culpable inferences, that each of the defendants

10 knew or was deliberately reckless in not knowing that the foregoing statements in the January 5,

11 2006 press release and conference call were materially false and misleading when made:

12 (a) Defendants Love, as Chairman and CEO, Titus, as CAO, and Levy as Senior

13 VP of Research and Development, were responsible for and/or knew about the clinical testing of

14 alfimeprase, the agreements with the FDA about the required p-value for SONOMA-2 and the target

15 product profile for marketing alfimeprase for CO. They were responsible for the reports and claims

16 relating to alfimeprase as well as the press releases issued by the Company. Specifically, defendants

17 were privy to the facts surrounding the results ofthe alfimeprase Phase 2 CO and PAO trials and the

18 specific facts surrounding the design of the alfimeprase Phase 3 CO and PAO trials, including the

19 requirements imposed by the FDA on SONOMA-2 (the alfimeprase Phase 3 CO trial).

20 (b) According to CW 1, defendant Love wrote the protocols for all ofthe clinical

21 trials of alfimeprase, including the protocol for SONOMA-2, and was a member ofthe "alfimeprase

22 team consisting of people primarily responsible for the testing and marketing of the drug.

23 Therefore, he had actual knowledge of the extremely stringent p-value of 0.00125 which the FDA

24 imposed on the SONOMA-2 trial and the "target product profile for marketing alfimeprase for CO.

25 (c) As they admitted first on December 11, 2006 and in more detail on June 26,

26 2007, defendants knew that the FDA had imposed an extremely stringent p-value requirement ofless

27 than 0.00125 for the alfimeprase Phase 3 CO trial (SONOMA-2), which was forty times less than the

28

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -34- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 38 of 79

1 standard p-value of 0.05, and that, because of the stringent p-value imposed by the FDA, success in

2 the Phase 3 trial and FDA approval were unlikely.

3 (d) Defendants knew or recklessly disregarded that the action ofcatheter insertion

4 can restore blood flow where there was a clot. This precise risk had been raised by CW1 prior to the

5 Class Period with high ranking officers of Nuvelo, including Love, Pena and Deitcher. Thus,

6 defendants knew that the results obtained in the Phase 2 trial of alfimeprase for PAO could have

7 been the result, in whole or in part, ofthe insertion ofthe catheter used to administer the alfimeprase,

8 rather than the action of the alfimeprase. The insertion ofthe catheter alone could have restored the

9 blood flow resulting in patients not requiring open surgery within 30 days. Thus, defendants knew or

10 recklessly disregarded that the Phase 2 trial of alfimeprase for PAO did not produce reliable results

11 that would accurately predict the success of alfimeprase in the Phase 3 trial or FDA approval, or that

12 would indicate there would be a "low risk path to FDA approval or "rapid path to the marketability

13 of the drug for PAO.

14 (e) Defendants knew or recklessly disregarded that their "power calculations

15 were not reliable because they were based upon placebo assumptions which had no reasonable basis.

16 Defendants did not know how many patients avoided open surgery for 30 days as a result of the

17 action ofthe catheter breaking up the clot in the Phase 2 PAO trial, and thus, had no reasonable basis

18 for assuming how many patients in the placebo arm would avoid open surgery because their clots

19 were broken up simply by the insertion of the catheter. According to defendants, these power

20 calculations were based on assumptions about the percentage ofclots dissolved in the placebo group,

21 without regard to the fact that blood flow is restored by disruption of a clot, even if it is not

22 dissolved, and restoration of blood flow avoids surgery.

23 (f) Because of Love's and Nuvelo's VP of Manufacturing's involvement with

24 alteplase while employed by Genentech, defendants knew or recklessly disregarded that the market

25 opportunity for alfimeprase for PAO was much smaller than represented to analysts and the market

26 because of competition from off-label use of other drugs and mechanical clot-busting techniques and

27 devices.

1 (g) Defendants knew that Nuvelo had an undisclosed "target product profile

2 which would be necessary to meet for the marketability and commercial success of alfimeprase in

3 CO, and that the Company would not proceed to market alfimeprase for that indication if the

4 SONOMA-2 trial results did not meet that profile, even ifthe drug was otherwise qualified for FDA

5 approval.

6 (h) Because defendants Love and Titus signed Nuvelo's filings with the SEC

7 during the Class Period, they knew or recklessly disregarded that Nuvelo had not disclosed known

8 material risks to the success of the Phase 3 trials, FDA approval and the commercial potential of

9 alfimeprase, as detailed herein in ¶1131-144.

10 99. The totality of these circumstances, in addition to facts alleged elsewhere in this

11 Complaint, give rise to a cogent inference which is stronger than any non-culpable inferences that

12 each of the defendants had actual knowledge or recklessly disregarded that their January 5, 2006

13 statements were materially false and misleading when made.

14 B. Defendants ' February 27, 2006 False and Misleading Statements

15 100. On February 27, 2006, the Company and Bayer issued a press release entitled

16 "Nuvelo and Bayer HealthCare Begin SONOMA-3, Second Phase 3 Trial ofAlfimeprase in Patients

17 With Central Venous Catheter Occlusion, which stated in relevant part:

18 Nuvelo Inc. (Nasdaq: NUVO) and Bayer HealthCare (BHC) today announced that they have begun patient enrollment in a second 19 pivotal Phase 3 clinical trial of lead product candidate, alfimeprase, for the treatment of central venous catheter occlusion (CO). 20

21 `We believe that alfimeprase has the potential to quickly dissolve 22 clots and rapidly restore the ability to infuse critical therapy such as chemotherapy or antibiotics through once occluded catheters,' said 23 Steven R. Deitcher, M.D., vice president of medical sciences for Nuvelo and former principal investigator of the Phase 2 trial. `We 24 look forward to completing the first trial in this program, SONOMA- 2, later this year and expect the Phase 3 trial results to confirm the 25 ability ofalfimeprase to restorefunction to occluded catheters in 15 minutes or less, as demonstrated in our Phase 2 trial.' 26 Previously announced results from a Phase 2 multi-center, 27 randomized, double-blind study in 55 patients with occluded central venous catheters demonstrated that alfimeprase restoredflow to 40 28 percent and 50percent ofoccluded catheters 5 and 15 minutes after

the first dose, respectively. By comparison, Cathflo(R)Activase(R) (alteplase) did not restore flow at either time point. Alfimeprase also 2 restored flow to 60 percent of occluded catheters at 120 minutes after the first dose and to 80 percent of occluded catheters at 120 minutes 3 after the second dose compared with 46 percent at 120 minutes after the first dose and 62 percent at 120 minutes after the second dose 4 with Cathflo(R)Activase(R).

5 101. On February 27, 2006, Nuvelo conducted a conference call with analysts to discuss

6 the Company's FY05 and 4Q05 results. Defendants Love, Titus and Levy each participated in and

7 spoke on behalf of Nuvelo during the call. On the call, Levy and Love provided the following

8 update on the status of the alfimeprase trials:

9 [Levy]: [I]n January of this year, the FDA granted alfimeprase fast track designation. This designation is reserved for drugs that 10 demonstrate the potential to address an unmet medical need and are intended for the treatment of a serious or life-threatening condition. 11 In the case of acute PAO, there is no currently available FDA approved drug making it an unmet medical need and the Phase 2 12 datafor alfimeprase has demonstrated that it has a realpotential to transform the treatment of this condition. 13

14 Having made progress on our initial clinical programs in 2006 we 15 will begin to implement our label expansion strategy for alfimeprase. We have always known that alfimeprase holds thepotential to treat 16 a wide range of clot disorders and that acute PAO and catheter occlusion represented the most rapid and low risk market entry 17 strategy for us. Now that we've advanced both of these initial programs, we are able to pursue follow-on opportunities for 18 alfimeprase being ischemic stroke and NDBT. We believe that alfimeprase has the potential to transform both of these markets 19 where currently there is little penetration by existing agents.

20

21 [Love] : Our partnership with Bayer is predicated on a belief that alfimeprase has the potential to transform treatmentfor the more 22 than 10 million people in the western world who sufferfrom blood clot related conditions each year and that the market opportunity 23 extends far beyond acute PAO and catheter occlusion... .

24 After our announcement with Bayer in January, we have moved swiftly to kick off the partnership. We are off to a great start and 25 have been working to establish the appropriate joint committees between our companies. In other words, we've already started to put 26 a solid foundation in place for our very successful collaboration and we continue to make excellent progress with alfimeprase 27 development.

1 1. Reasons Why Defendants' February 27, 2006 Statements Were False and Misleading 2 102. The statements in the February 27, 2006 press release and the February 27, 2006 3 conference call that Nuvelo expected the Phase 3 trials to "confirm the ability of alfimeprase to 4 restore function to occluded catheters, as "demonstrated' in the Phase 2 trial, and that "acute PAO 5 and catheter occlusion represented the most rapid and low risk market entry strategy for the 6 Company, were false because the Phase 2 data was not as reliable or significant as defendants had 7 led the market to believe, nor were the existing risks to FDA Approval or commercial marketability 8 of alfimeprase for PAO and CO fully disclosed. 9 103. As alleged previously, defendants knew that blood flow in some patients enrolled in 10 the NAPA PAO trials would be restored simply by inserting the catheter into the clot to deliver the 11 drug, rather than through any action of alfimeprase, and had no basis for representing to the market 12 the degree to which the drug caused the purportedly successful Phase 2 results. Based on the small 13 size ofthe CO Phase 2 trial and the lower than expected rate of catheter clearance in the comparator 14 alteplase arm, defendants also had no reasonable basis for predicting success in the Phase 3 trials for 15 CO, because they did not know whether the dose ofalfimeprase chosen for the study in SONOMA-2 16 would yield the required results or would be appropriate for the commercial success of alfimeprase 17 in this indication. As a result, the regulatory path for approval for CO was far from "low risk, nor 18 was there a "high probability of success in the Phase 3 PAO and CO trials, as defendants had 19 previously represented. 20 104. These statements, together with defendants' other statements regarding the purported 21 success of the Phase 2 trials and the likelihood of success in the Phase 3 trials as elsewhere alleged, 22 were also materially false and misleading to investors because Nuvelo omitted to disclose, in the 23 press release, on the conference call, or elsewhere, known risks that reduced the likelihood that the 24 Phase 2 results could be replicated in Phase 3 trials, that the Phase 3 trials would succeed or that the 25 drug would be marketable, including that: (i) in the Phase 2 PAO trial, the blood clot may have 26 simply been broken up by the action ofthe catheter pushing into the clot, rather than dissolved by the 27 action of the drug, a possibility that had been raised internally at Nuvelo even before the Phase 2 28

1 PAO trials were completed; (ii) in the Phase 3 CO trial, Nuvelo had agreed with the FDA to

2 demonstrate success at a statistical significance level that wasforty times more stringent than what

3 the market believed, rendering success much less likely; (iii) the market opportunity for the drug in

4 PAO was much smaller than represented to analysts and the market because ofcompetition from off-

5 label use of other drugs and mechanical clot-busting techniques, the potential impact of which was

6 not timely or accurately disclosed to investors; (iv) Nuvelo had an undisclosed "target product

7 profile which would be necessary to meet in order for the Company to market alfimeprase for CO,

8 and the Company would not proceed to market alfimeprase for that indication if the trial results did

9 not meet that profile, even if the drug was otherwise qualified for FDA approval.

11 105. The following facts, as alleged in more detail elsewhere in the Complaint, give rise to

12 a cogent inference which is stronger than any non-culpable inferences, that each of the defendants

13 knew or was deliberately reckless in not knowing that the foregoing statements in the February 27,

26 Therefore, he had actual knowledge of the extremely stringent p-value of less than 0.00125 which

27 the FDA imposed on the SONOMA-2 trial and the "target product profile for marketing

28 alfimeprase for CO.

1 (c) As they admitted first on December 11, 2006 and in more detail on June 26,

2 2007, defendants knew that the FDA had imposed an extremely stringent p-value requirement ofless

3 than 0.00125 for the alfimeprase Phase 3 CO trial (SONOMA-2), which was forty times less than the

4 standard p-value of 0.05, and that, because of the stringent p-value imposed by the FDA, success in

5 the Phase 3 trial and FDA approval were unlikely.

6 (d) Defendants knew or recklessly disregarded that the action ofcatheter insertion

7 can restore blood flow where there was a clot. This precise risk had been raised by CW1 prior to the

8 Class Period with high ranking officers of Nuvelo, including Love, Pena and Deitcher. Thus,

9 defendants knew that the results obtained in the Phase 2 trial of alfimeprase for PAO could have

11 rather than the action of the alfimeprase. The insertion ofthe catheter alone could have restored the

13 recklessly disregarded that the Phase 2 trial of alfimeprase for PAO did not produce reliable results

14 that would predict the success of alfimeprase in the Phase 3 trial or FDA approval, or that would

15 indicate there would be a "low risk path to FDA approval or "rapid path to the marketability ofthe

16 drug for PAO.

17 (e) Defendants knew or recklessly disregarded that their "power calculations

18 were not reliable because they were based upon placebo assumptions which had no reasonable basis.

19 Defendants did not know how many patients avoided open surgery for 30 days as a result of the

20 action ofthe catheter breaking up the clot in the Phase 2 PAO trial, and thus, had no reasonable basis

21 for assuming how many patients in the placebo arm would avoid open surgery because their clots

24 without regard to the fact that blood flow is restored by disruption of a clot, even if it is not

25 dissolved, and restoration of blood flow avoids surgery.

26 (f) Because of Love's and Nuvelo's VP of Manufacturing's involvement with

27 alteplase while employed by Genentech, defendants knew or recklessly disregarded that the market

28 opportunity for alfimeprase for PAO was much smaller than represented to analysts and the market

because of competition from off-label use of other drugs and mechanical clot-busting techniques and

2 devices.

3 (g) Defendants knew that Nuvelo had an undisclosed "target product profile

4 which would be necessary to meet for the marketability and commercial success of alfimeprase in

5 CO, and that the Company would not proceed to market alfimeprase for that indication if the

6 SONOMA-2 trial results did not meet that profile, even ifthe drug was otherwise qualified for FDA

7 approval.

8 (h) Because defendants Love and Titus signed Nuvelo's filings with the SEC

9 during the Class Period, they knew or recklessly disregarded that Nuvelo had not disclosed known

10 material risks to the success of the Phase 3 trials, FDA approval and the commercial potential of

11 alfimeprase, as detailed herein in ¶1131-144.

12 106. The totality of these circumstances, in addition to facts alleged elsewhere in this

13 Complaint, give rise to a cogent inference which is stronger than any non-culpable inferences that

14 each of the defendants had actual knowledge or recklessly disregarded that their February 27, 2006

15 statements were materially false and misleading when made.

16 C. Misleading Statements in Nuvelo's FY05 Report on Form 10-K

17 107. On March 15, 2006, Nuvelo filed with the SEC its Report on Form 10-K for its 2005

18 fiscal year, ending December 31, 2005, signed by defendants Titus and Love.

19 108. Regarding the Phase 2 clinical trials of alfimeprase, the 10-K Report stated:

20 We completed our Phase 2 clinical trial in patients with acute PAO in the second quarter of 2004. This trial was an open label, dose-escalation study evaluating the 21 safety and activity of alfimeprase. The trial enrolled 113 patients in multiple centers in the United States, Europe, Russia and other locations. The Phase 2 results 22 indicate that alfimeprase has thepotential to offer significant advances in the rapid resolution of a blood clot while minimizing potentially fatal side effects such as 23 intracerebral hemorrhage and other bleeding complications. Analysis ofthe Phase 2 results showed that alfimeprase has thepotential topartially or completely break 24 up blood clots within four hours of initiation of dosing with rates of up to 76 percent and to restore arterialfZow with rates ofup to 60percent Up to 69percent 25 ofstudypatients were able to avoid open vascular surgical intervention in the 30 daysfollowing treatment with alfimeprase. Among the 113patients enrolled, there 26 were no intracerebral hemorrhages or deaths at 30 days. There were seven major bleeding events reported, none ofwhich was categorized as systemic bleeding events 27 and only one of which was categorized by the investigator as possibly related to alfimeprase. Incidents of transient hypotension were also reported and were dose- 28 related. Events associated with distal embolism were also noted. We do not believe

that these events were more significant in number or severity than similar events associated with other therapies delivered by catheter to blood clots. 2

3 In the third quarter of 2004, we completed patient enrollment in a Phase 2 multi- 4 center, double-blind, randomized study in 55 patients with occluded central venous catheters comparing three doses (0.3 mg, 1.0 mg and 3.0 mg) of alfimeprase against 5 the approved dose of Cathflo Activase (2.0 mg). The alfimeprase 3.0 mg dose produced cumulativeflow rates of40percent atfive minutes after thefirst dose, 50 6 percent at 15 minutes after thefirst dose, 60percent at 30 minutes and 120 minutes after the first dose, and 80 percent at 120 minutes after the second dose. This is 7 compared to Cathflo Activase, which producedflow rates ofzero percent atfive minutes after the first dose, zero percent at 15 minutes after the first dose, 23 8 percent at 30 minutes after thefirst dose, 46percent at 120 minutes after thefirst dose, and 62 percent at 120 minutes after the second dose. No major hemorrhagic 9 events were reported in any treated patients and only one patient had a catheter- related infection. 10 109. A letter to shareholders accompanying Nuvelo's 2005 Annual Report to Shareholders 11 signed by Love, similarly stated: 12 Alfimeprase is being developed as a clot dissolver and has the potential to 13 fundamentally change the treatment ofa wide range ofclot related disorders. We chose our initial clinical programs for alfimeprase in acute peripheral arterial 14 occlusion (PAO) and catheter occlusion (CO), topermit more rapid and lower risk market entry, with the expectation that we would later expand our efforts into 15 additional indications. We are well on our way to achieving this goal

16

17 Given alfimeprase's speed ofaction and safetyprofile, we believe it could offer a superior alternative to currently available therapies in these large and undeserved 18 markets. We expect to initiate a Phase 2 trial with alfimeprase in stroke in the second half of 2006 and a Phase 2 trial in DVT in 2007. 19 110. The Report on Form 10-K did not include any specific warnings about the known 20 risks of the applicability of the Phase 2 results to the ongoing Phase 3 trials, the likelihood of FDA 21 approval in view ofthe FDA's extremely stringent p-value requirements for the Phase 3 CO trial and 22 the undisclosed target product profile for the marketability of the drug for CO. 23 1. Reasons Why the Statements in the FY05 Report on Form 10- 24 K Were Materially False and Misleading to Investors.

25 111. The statements in the Report on Form 10-K and accompanying shareholder letter that

26 the Phase 2 results for PAO indicate alfimeprase's ability to "offer significant advances in the rapid

27 resolution of [] blood clot[s] and that it "has the potential to partially or completely break up blood

28 clots within four hours, were false and misleading because the Phase 2 data was not as reliable or

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -42- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 46 of 79

1 significant as defendants had led the market to believe, nor were the existing risks to FDA Approval

2 or commercial marketability of alfimeprase for PAO and CO fully disclosed.

3 112. As alleged previously, defendants knew that blood flow in some patients enrolled in

4 the NAPA PAO trials would be restore simply by inserting the catheter into the clot to deliver the

5 drug, rather than through any action of alfimeprase, and had no basis for representing to the market

6 the degree to which the drug caused the purportedly successful Phase 2 results . Based on the small

7 size ofthe CO Phase 2 trial and the lower than expected rate of catheter clearance in the comparator

8 alteplase arm, defendants also had no reasonable basis for predicting success in the Phase 3 trials for

9 CO, because they did not know whether the dose ofalfimeprase chosen for the study in SONOMA-2

10 would yield the required results or would be appropriate for the commercial success of alfimeprase

11 in this indication. As a result, the regulatory path for approval for CO was far from "low risk, nor

12 was there a "high probability of success in the Phase 3 PAO and CO trials , as defendants had

13 previously represented.

14 113. These statements, together with defendants' other statements regarding the purported

15 success of the Phase 2 trials and the likelihood of success in the Phase 3 trials as elsewhere alleged,

16 were also materially false and misleading to investors because Nuvelo omitted to disclose, in the

17 press release, on the conference call, or elsewhere, known risks that reduced the likelihood that the

18 Phase 2 results could be replicated in Phase 3 trials, that the Phase 3 trials would succeed or that the

19 drug would be marketable, including that: (i) in the Phase 2 PAO trial, the blood clot may have

20 simply been broken up by the action ofthe catheter pushing into the clot, rather than dissolved by the

21 action of the drug, a possibility that had been raised internally at Nuvelo even before the Phase 2

22 PAO trials were completed; (ii) in the Phase 3 CO trial, Nuvelo had agreed with the FDA to

23 demonstrate success at a statistical significance level that wasforty times more stringent than what

24 the market believed, rendering success much less likely; (iii) the market opportunity for the drug in

25 PAO was much smaller than represented to analysts and the market because ofcompetition from off-

26 label use of other drugs and mechanical clot-busting techniques, the potential impact of which was

27 not timely or accurately disclosed to investors; (iv) Nuvelo had an undisclosed "target product

28 profile which would be necessary to meet in order for the Company to market alfimeprase for CO,

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -43- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 47 of 79

1 and the Company would not proceed to market alfimeprase for that indication if the trial results did

2 not meet that profile, even if the drug was otherwise qualified for FDA approval.

4 114. The following facts, as alleged in more detail elsewhere in the Complaint, give rise to

5 a cogent inference which is stronger than any non-culpable inferences, that each of the defendants

6 knew or was deliberately reckless in not knowing that the statements in the FY05 Report on Form

7 10-K were materially false and misleading when made:

8 (a) Defendants Love, as Chairman and CEO, Titus, as CAO and Levy as Senior

9 VP of Research and Development, were responsible for and/or knew about the clinical testing of

10 alfimeprase, the agreements with the FDA about the required p-value for SONOMA-2 and the target

11 product profile for marketing alfimeprase for CO. They were responsible for the reports and claims

12 relating to alfimeprase as well as the press releases issued by the Company. Specifically, defendants

13 were privy to the facts surrounding the results ofthe alfimeprase Phase 2 CO and PAO trials and the

14 specific facts surrounding the design of the alfimeprase Phase 3 CO and PAO trials, including the

15 requirements imposed by the FDA on SONOMA-2 (the alfimeprase Phase 3 CO trial).

16 (b) According to CW 1, defendant Love wrote the protocols for all ofthe clinical

17 trials of alfimeprase, including the protocol for SONOMA-2, and was a member ofthe "alfimeprase

18 team consisting of people primarily responsible for the testing and marketing of the drug.

19 Therefore, he had actual knowledge of the extremely stringent p-value of less than 0.00125 which

20 the FDA imposed on the SONOMA-2 trial and the "target product profile for marketing

21 alfimeprase for CO.

22 (c) As they admitted first on December 11, 2006 and in more detail on June 26,

23 2007, defendants knew that the FDA had imposed an extremely stringent p-value requirement ofless

24 than 0.00125 for the alfimeprase Phase 3 CO trial (SONOMA-2), which was forty times less than the

25 standard p-value of 0.05, and that, because of the stringent p-value imposed by the FDA, success in

26 the Phase 3 trial and FDA approval were unlikely.

27 (d) Defendants knew or recklessly disregarded that the action ofcatheter insertion

28 can restore blood flow where there was a clot. This precise risk had been raised by CW1 prior to the

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -44- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 48 of 79

1 Class Period with high ranking officers of Nuvelo, including Love, Pena and Deitcher. Thus,

2 defendants knew that the results obtained in the Phase 2 trial of alfimeprase for PAO could have

3 been the result, in whole or in part, ofthe insertion ofthe catheter used to administer the alfimeprase,

4 rather than the action of the alfimeprase. The insertion ofthe catheter alone could have restored the

5 blood flow resulting in patients not requiring open surgery within 30 days. Thus, defendants knew or

6 recklessly disregarded that the Phase 2 trial of alfimeprase for PAO did not produce reliable results

7 that would predict the success of alfimeprase in the Phase 3 trial or FDA approval, or that would

8 indicate there would be a "low risk path to FDA approval or "rapid path to the marketability ofthe

9 drug for PAO.

10 (e) Defendants knew or recklessly disregarded that their "power calculations

11 were not reliable because they were based upon placebo assumptions which had no reasonable basis.

12 Defendants did not know how many patients avoided open surgery for 30 days as a result of the

13 action ofthe catheter breaking up the clot in the Phase 2 PAO trial, and thus, had no reasonable basis

14 for assuming how many patients in the placebo arm would avoid open surgery because their clots

15 were broken up simply by the insertion of the catheter. According to defendants, these power

16 calculations were based on assumptions about the percentage ofclots dissolved in the placebo group,

17 without regard to the fact that blood flow is restored by disruption of a clot, even if it is not

18 dissolved, and restoration of blood flow avoids surgery.

19 (f) Because of Love's and Nuvelo's VP of Manufacturing's involvement with

20 alteplase while employed by Genentech, defendants knew or recklessly disregarded that the market

21 opportunity for alfimeprase for PAO was much smaller than represented to analysts and the market

22 because of competition from off-label use of other drugs and mechanical clot-busting techniques and

23 devices.

24 (g) Defendants knew that Nuvelo had an undisclosed "target product profile

25 which would be necessary to meet for the marketability and commercial success of alfimeprase in

26 CO, and that the Company would not proceed to market alfimeprase for that indication if the

27 SONOMA-2 trial results did not meet that profile, even ifthe drug was otherwise qualified for FDA

28 approval.

(h) Because defendants Love and Titus signed Nuvelo's filings with the SEC

2 during the Class Period, they knew or recklessly disregarded that Nuvelo had not disclosed known

3 material risks to the success of the Phase 3 trials, FDA approval and the commercial potential of

4 alfimeprase, as detailed herein in ¶1131-144.

5 115. The totality of these circumstances, in addition to facts alleged elsewhere in this

6 Complaint, give rise to a cogent inference which is stronger than any non-culpable inferences that

7 each of the defendants had actual knowledge or recklessly disregarded that the statements in the

8 FY05 Report on Form 10-K and the letter to shareholders accompanying Nuvelo's 2005 Annual

9 Report to Shareholders were materially false and misleading when made.

10 D. Defendants' False and Misleading Statements in April 10, 2006 Press Release 11 116. On April 10, 2006, defendants, along with Bayer, issued a press release entitled 12 "Nuvelo and Bayer Healthcare Begin NAPA-3, Second Pivotal Phase 3 Trial of Alfimeprase for 13 Acute Peripheral Arterial Occlusion, which announced the commencement ofthe NAPA 2 trial, and 14 then stated, in relevant part: 15 Previously announced results from the NAPA-1 trial, a Phase 2 16 dose- escalation study, demonstrated that alfimeprase can restore arterial bloodflow within four hours ofinitiation ofdosing, has a 17 favorable safety profile with minimal bleeding complications, and resulted in a majority ofpatients avoiding open vascular surgery 18 within 30 days oftreatment.

19 1. Reasons Why Defendants' April 10, 2006 Statement Was False and Misleading 20 117. The statement in the April 10, 2006 press release that the Phase 2 study in PAO had 21 "demonstrated that alfimeprase can restore arterial blood flow within four hours of initiation of 22 dosing was false because in fact, blood flow in the patients enrolled in the NAPA PAO trials had 23 been restored simply by inserting the catheter into the clot to deliver the drug, rather than through 24 any action of alfimeprase. The statement, together with defendants' other statements regarding the 25 purported success ofthe Phase 2 trials and the likelihood of success in the Phase 3 trials as elsewhere 26 alleged, were also materially false and misleading to investors because Nuvelo omitted to disclose in 27 the press release, or elsewhere, known risks that reduced the likelihood that the Phase 2 results could 28

1 be replicated in Phase 3 trials, that the Phase 3 trials would succeed or that the drug would be

2 marketable, including that: (i) in the Phase 2 PAO trial, the blood clot may have simply been broken

3 up by the action of the catheter pushing into the clot, rather than dissolved by the action of the drug,

10 118. The following facts, as alleged in more detail elsewhere in the Complaint, give rise to

11 a cogent inference which is stronger than any non-culpable inferences, that each of the defendants

12 knew or was deliberately reckless in not knowing that the foregoing statement in the April 10, 2006

13 press release was materially false and misleading when made:

14 (a) Defendants Love, as Chairman and CEO, Titus, as CAO, and Levy as Senior

1 blood flow resulting in patients not requiring open surgery within 30 days. Thus, defendants knew or

2 recklessly disregarded that the Phase 2 trial of alfimeprase for PAO did not produce reliable results

3 that would predict the success of alfimeprase in the Phase 3 trial or FDA approval, or that would

5 drug for PAO.

6 (d) Defendants knew or recklessly disregarded that their "power calculations

7 were not reliable because they were based upon placebo assumptions which had no reasonable basis.

8 Defendants did not know how many patients avoided open surgery for 30 days as a result of the

9 action ofthe catheter breaking up the clot in the Phase 2 PAO trial, and thus, had no reasonable basis

10 for assuming how many patients in the placebo arm would avoid open surgery because their clots

11 were broken up simply by the insertion of the catheter. According to defendants, these power

12 calculations were based on assumptions about the percentage ofclots dissolved in the placebo group,

13 without regard to the fact that blood flow is restored by disruption of a clot, even if it is not

14 dissolved, and restoration of blood flow avoids surgery.

17 opportunity for alfimeprase for PAO was much smaller than represented to analysts and the market

18 because of competition from off-label use of other drugs and mechanical clot-busting techniques and

19 devices. According to defendants these power calculators were based on assumptions about the

20 percentage of clots dissolved in the placebo group, without regard to the fact that blood flow is

21 restored with disruption of a clot that is not dissolved, and restoration ofblood flow avoids surgery.

22 (f) Because defendants Love and Titus signed Nuvelo's filings with the SEC

23 during the Class Period, they knew or recklessly disregarded that Nuvelo had not disclosed known

2 statement was materially false and misleading when made.

3 E. Defendants ' May 5, 2006 False and Misleading Statements

4 120. On May 5, 2006, Nuvelo conducted a conference call with analysts to discuss the

5 Company's 1 Q06 results . Defendants Love, Titus and Levy each participated in and spoke on behalf

6 ofNuvelo during the call. During the call, defendants made the following statements in response to

7 questions from analysts regarding the ongoing NAPA trials for PAO:

8 [Love]: So you asked two questions. I'll answer the statistical one first. Yes, we took a very conservative case when we prepared the 9 trial. Obviously in an ideal world, everyone who received placebo wouldn't respond to therapy and require surgery, and the vast 10 components of people who received alfimeprase would respond[.] But we took a conservative case scenario and allowedfor a certain 11 percentage ofpatients to be deemed to respond to placebo; and as we've discussed in past conferences in particular, the statistical 12 power is still overwhelming for this trial, and we have 90% [INAUDIBLE], 22% difference in the ultimate rate between the two 13 therapies, placebo and alfimeprase.

14

15 [Titus]:... [W]e believe that the prudent case to plan for is two trials for approval. That's typically what's required by the FDA. And 16 really the driver here is not the statistical power for approving efficacy, because we believe that can be done with a relatively small 17 patient sample; but we need to generate a reasonable size patient safety database to seek approval. So that's certainly the way we're 18 planning.

19

20 [WJe believe we still have overwhelming statisticalpower to detect the difference between and active therapy such as alfimeprase - 21 which is indeed very active based on our Phase 2 studies to date - andplacebo. 22 1. Reasons Why Defendants' May 5, 2006 Statements Were False 23 and Misleading

24 121. The statements by Love and Titus on the May 5, 2006 conference call that the Phase 3

25 NAPA trials for PAO were "conservatively designed with "overwhelming statistical power to

26 detect differences between alfimeprase- and placebo-caused results, and that "the driver here is not

27 the statistical power for efficacy because the drug was "indeed very active based on our Phase 2

28 studies, were false because in fact, blood flow in the patients enrolled in the NAPA PAO trials had

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -49- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 53 of 79

1 been restored simply by inserting the catheter into the clot to deliver the drug, rather than through

2 any action of alfimeprase. These statements, together with defendants' other statements regarding

3 the purported success of the Phase 2 trials and the likelihood of success in the Phase 3 trials as

4 elsewhere alleged, were also materially false and misleading to investors because Nuvelo omitted to

5 disclose, on the conference call, or elsewhere, known risks that reduced the likelihood that the

6 Phase 2 results could be replicated in Phase 3 trials, that the Phase 3 trials would succeed or that the

7 drug would be marketable, including that: (i) in the Phase 2 PAO trial, the blood clot may have

8 simply been broken up by the action ofthe catheter pushing into the clot, rather than dissolved by the

9 action of the drug, a possibility that had been raised internally at Nuvelo even before the Phase 2

10 PAO trials were completed; and (ii) the market opportunity for the drug in PAO was much smaller

11 than represented to analysts and the market because of competition from off-label use ofother drugs

12 and mechanical clot-busting techniques, the potential impact of which was not timely or accurately

13 disclosed to investors.

15 122. The following facts, as alleged in more detail elsewhere in the Complaint, give rise to

16 a cogent inference which is stronger than any non-culpable inferences, that each of the defendants

17 knew or was deliberately reckless in not knowing that the foregoing statements in the May 5, 2006

5 each of the defendants had actual knowledge or recklessly disregarded that their May 5, 2006

6 statements were materially false and misleading when made.

7 F. Defendants' August 3, 2006 False and Misleading Statements

8 124. On August 3, 2006, Nuvelo conducted a conference call with analysts to discuss the

9 Company's 2Q06 financial results. Defendants Love and Levy each participated in and spoke on

10 behalf of Nuvelo during the call. During the call, defendant Love reassured investors that the

11 Company's "collaboration with Bayer HealthCare to develop and commercialize alfimeprase

12 continues to go very well, and [that Nuvelo was] tracking to [its] goals and milestones laid out for

13 the program. Although Levy highlighted the progress Nuvelo was making on the

14 commercialization of alfimeprase and touted Bayer's continuing support, he refused to discuss or

15 disclose any clinical data with respect to CO:

16 [Levy]: Moving now to our second target indication, catheter 17 occlusion. We arepleased to announce that resultsfrom ourphase II trial of alfimeprase in its indication were published in the July 18 1st issue of the Journal of Clinical Oncology. In addition, our phase III program in this indication is progressing well. We 19 achieved our milestone of initiating the second phase III catheter occlusion trial, SONOMA-3, in the first half of 2006. This open- 20 label single-arm trial is evaluating the safety and efficacy of three milligrams of alfimeprase in 800 patients with occluded central 21 venous catheters.

22 We also continue to be on track to complete enrollment in SONOMA-2, the first trial in this program, in the second half of 23 2006, and expect to provide top-line results several months afterwards. More complete analysis ofthe data will bepresented at 24 an appropriate medical conference as soon as possible thereafter.

25 125. In addition, in response to questions from an analyst, defendant Levy stated the

26 following with respect to PAO:

27 [Levy]: So, as you suggest, the group of patients that present are heterogeneous . Almost all the patients , ifnot all the patients, do have 28 some sort of underlying fixed peripheral vascular disease, and that a

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -52- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 56 of 79

1 thrombus generally forms on top ofthat when flow is diminished to a critical stage . We do of course select in this trial for patients who 2 have had an acute occlusion of less than 14 days. That's one thing we do. And obviously I have no data to share with you about this 3 particular trial, but I can say that we were very gratified in phase [21 tofind that alfimeprase worked very well on big clots and on small 4 clots, and we've discussed that in the past, that we've had some examples of very large clots, clots up to 60 centimeters in length, 5 that we've dissolved rapidly.

6 And it's worked on what we thought were new clots and old clots, based on the angiograms that we read showing extensive 7 collateralizations, which tend to be evidence ofan older clot. And on top of that, in phase I, we looked at patients who had chronic 8 peripheral vascular disease where the burden of their illness was fixed disease and very little was acute thrombus. And we were 9 gratified that in 40% of those patients as well we could see improvements on the angiogram and restoration ofbloodflow. 10 1. Reasons Why Statements Made on the August 3, 2006 11 Conference Call Were False and Misleading.

12 126. The statements on the August 3, 2006 conference call that Nuvelo's effort to

13 commercialize alfimeprase "continues to go very well, and [that Nuvelo was] tracking to [its] goals

14 and milestones laid out for the program, that Nuvelo was "gratified ... to find that alfimeprase

15 worked very well on big clots and on small clots in PAO that it "had some examples of very large

16 clots, clots up to 60 centimeters in length, that we've dissolved rapidly, and that alfimeprase had

17 "worked on what we thought were new clots and old clots and improved blood flows in 40% of

18 patients in the Phase 1 trials were false because the Phase 2 data was not as reliable or significant as

19 defendants had led the market to believe, nor were the existing risks to FDA Approval or

20 commercial marketability of alfimeprase for PAO and CO fully disclosed.

21 127. As alleged previously, defendants knew that blood flow in some patients enrolled in

22 the NAPA PAO trials would be restore simply by inserting the catheter into the clot to deliver the

23 drug, rather than through any action of alfimeprase, and had no basis for representing to the market

24 the degree to which the drug caused the purportedly successful Phase 2 results. Based on the small

25 size ofthe CO Phase 2 trial and the lower than expected rate of catheter clearance in the comparator

26 alteplase arm, defendants also had no reasonable basis for predicting success in the Phase 3 trials for

27 CO, because they did not know whether the dose ofalfimeprase chosen for the study in SONOMA-2

28 would yield the required results or would be appropriate for the commercial success of alfimeprase

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -53- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 57 of 79

1 in this indication. As a result, the regulatory path for approval for CO was far from "low risk, nor

2 was there a "high probability of success in the Phase 3 PAO and CO trials , as defendants had

3 previously represented.

4 128. These statements, together with defendants' other statements regarding the purported

5 success of the Phase 2 trials and the likelihood of success in the Phase 3 trials as elsewhere alleged,

6 were also materially false and misleading to investors because Nuvelo omitted to disclose, in the

7 press release, on the conference call, or elsewhere, known risks that reduced the likelihood that the

8 Phase 2 results could be replicated in Phase 3 trials, that the Phase 3 trials would succeed or that the

9 drug would be marketable, including that: (i) in the Phase 2 PAO trial, the blood clot may have

10 simply been broken up by the action ofthe catheter pushing into the clot, rather than dissolved by the

11 action of the drug, a possibility that had been raised internally at Nuvelo even before the Phase 2

12 PAO trials were completed; (ii) in the Phase 3 CO trial, Nuvelo had agreed with the FDA to

13 demonstrate success at a statistical significance level that wasforty times more stringent than what

14 the market believed, rendering success much less likely; (iii) the market opportunity for the drug in

15 PAO was much smaller than represented to analysts and the market because ofcompetition from off-

16 label use of other drugs and mechanical clot-busting techniques, the potential impact of which was

17 not timely or accurately disclosed to investors; (iv) Nuvelo had an undisclosed "target product

18 profile which would be necessary to meet in order for the Company to market alfimeprase for CO,

19 and the Company would not proceed to market alfimeprase for that indication if the trial results did

20 not meet that profile, even if the drug was otherwise qualified for FDA approval.

21 2. Scienter

22 129. The following facts, as alleged in more detail elsewhere in the Complaint, give rise to

23 a cogent inference which is stronger than any non-culpable inferences, that each of the defendants

24 knew or was deliberately reckless in not knowing that the foregoing statements in the August 3, 2006

25 conference call were materially false and misleading when made:

26 (a) Defendants Love, as Chairman and CEO, Titus, as CAO, and Levy as Senior

27 VP of Research and Development, were responsible for and/or knew about the clinical testing of

28 alfimeprase, the agreements with the FDA about the required p-value for SONOMA-2 and the target

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -54- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 58 of 79

1 product profile for marketing alfimeprase for CO. They were responsible for the reports and claims

2 relating to alfimeprase as well as the press releases issued by the Company. Specifically, defendants

3 were privy to the facts surrounding the results ofthe alfimeprase Phase 2 CO and PAO trials and the

4 specific facts surrounding the design of the alfimeprase Phase 3 CO and PAO trials , including the

5 requirements imposed by the FDA on SONOMA-2 (the alfimeprase Phase 3 CO trial).

6 (b) According to CW 1, defendant Love wrote the protocols for all ofthe clinical

7 trials of alfimeprase, including the protocol for SONOMA-2, and was a member ofthe "alfimeprase

8 team consisting of people primarily responsible for the testing and marketing of the drug.

9 Therefore, he had actual knowledge of the extremely stringent p-value of less than 0.00125 which

10 the FDA imposed on the SONOMA-2 trial and the "target product profile for marketing

11 alfimeprase for CO.

12 (c) As they admitted first on December 11, 2006 and in more detail on June 26,

13 2007, defendants knew that the FDA had imposed an extremely stringent p-value requirement ofless

14 than 0.00125 for the alfimeprase Phase 3 CO trial (SONOMA-2), which was forty times less than the

15 standard p-value of 0.05, and that, because of the stringent p-value imposed by the FDA, success in

16 the Phase 3 trial and FDA approval were unlikely.

17 (d) Defendants knew or recklessly disregarded that the action ofcatheter insertion

18 can restore blood flow where there was a clot. This precise risk had been raised by CW1 prior to the

19 Class Period with high ranking officers of Nuvelo, including Love, Pena and Deitcher. Thus,

20 defendants knew that the results obtained in the Phase 2 trial of alfimeprase for PAO could have

21 been the result, in whole or in part, ofthe insertion ofthe catheter used to administer the alfimeprase,

22 rather than the action of the alfimeprase. The insertion ofthe catheter alone could have restored the

23 blood flow resulting in patients not requiring open surgery within 30 days. Thus, defendants knew or

24 recklessly disregarded that the Phase 2 trial of alfimeprase for PAO did not produce reliable results

25 that would predict the success of alfimeprase in the Phase 3 trial or FDA approval, or that would

26 indicate there would be a "low risk path to FDA approval or "rapid path to the marketability ofthe

27 drug for PAO.

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -55- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 59 of 79

1 (e) Defendants knew or recklessly disregarded that their "power calculations

2 were not reliable because they were based upon placebo assumptions which had no reasonable basis.

3 Defendants did not know how many patients avoided open surgery for 30 days as a result of the

4 action ofthe catheter breaking up the clot in the Phase 2 PAO trial, and thus, had no reasonable basis

5 for assuming how many patients in the placebo arm would avoid open surgery because their clots

6 were broken up simply by the insertion of the catheter. According to defendants, these power

7 calculations were based on assumptions about the percentage ofclots dissolved in the placebo group,

8 without regard to the fact that blood flow is restored by disruption of a clot, even if it is not

9 dissolved, and restoration of blood flow avoids surgery.

10 (f) Because of Love's and Nuvelo's VP of Manufacturing's involvement with

11 alteplase while employed by Genentech, defendants knew or recklessly disregarded that the market

12 opportunity for alfimeprase for PAO was much smaller than represented to analysts and the market

13 because of competition from off-label use of other drugs and mechanical clot-busting techniques and

14 devices.

15 (g) Defendants knew that Nuvelo had an undisclosed "target product profile

16 which would be necessary to meet for the marketability and commercial success of alfimeprase in

17 CO, and that the Company would not proceed to market alfimeprase for that indication if the

18 SONOMA-2 trial results did not meet that profile, even ifthe drug was otherwise qualified for FDA

19 approval.

20 (h) Because defendants Love and Titus signed Nuvelo's filings with the SEC

21 during the Class Period, they knew or recklessly disregarded that Nuvelo had not disclosed known

22 material risks to the success of the Phase 3 trials, FDA approval and the commercial potential of

23 alfimeprase, as detailed herein in ¶1131-144.

24 130. The totality of these circumstances, in addition to facts alleged elsewhere in this

25 Complaint, give rise to a cogent inference which is stronger than any non-culpable inferences that

26 each of the defendants had actual knowledge or recklessly disregarded that their August 3, 2006

27 statements were materially false and misleading when made.

28

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -56- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 60 of 79

1 IX. MISLEADING RISK WARNINGS PROVIDE NO SAFE HARBOR

2 131. The statutory safe harbor provided for forward-looking statements under certain

3 circumstances does not apply to any ofthe allegedly false statements pleaded in this Complaint. The

4 specific statements pleaded herein were not forward-looking and were not identified as "forward-

5 looking statements when made. Rather, the false statements alleged herein are statements of

6 present fact, including statements rendered misleading by defendants' failure to accurately or

7 completely disclose current known risks to its business and operations.

8 132. To the extent there were any forward-looking statements, there were no meaningful

9 cautionary statements identifying important factors that could cause actual results to differ materially

10 from those in the purportedly forward-looking statements. Alternatively, to the extent that the

11 statutory safe harbor does apply to any forward-looking statements pleaded herein, defendants are

12 liable for those false forward-looking statements because at the time each ofthose forward-looking

13 statements was made, the particular speaker knew that the particular forward-looking statement was

14 false, and/or the forward-looking statement was authorized and/or approved by an executive officer

15 of Nuvelo who knew that those statements were false when made.

16 133. Although Nuvelo's publicly-filed reports with the SEC during the Class Period

17 included a section purporting to disclose material risks to its operations, including risks relating to

18 on-going clinical trials, those risk warnings were themselves misleading to investors. Nuvelo's

19 Report on Form 10-K, issued on March 15, 2006, did not include, for example, any specific

20 warnings regarding the risks that the purportedly favorable results ofthe Phase 2 PAO trials were the

21 result of the catheter used to deliver the drug breaking up the blood clot, that the FDA had imposed

22 an extremely stringent statistical significance standard - the 0.00 125 p-value - on the Phase 3 CO

23 trial, or that Nuvelo had an undisclosed "target product profile which would be necessary to meet in

24 order for the Company to market alfimeprase for CO, and the Company would not proceed to market

25 alfimeprase for that indication ifthe trial results did not meet that profile even ifthe results otherwise

26 qualified for FDA approval.

27 134. Instead, the Report included only general and generic risk warnings, such as "Our

28 near-term success is dependent on the success of our lead product candidate, alfimeprase, and we

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -57- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 61 of 79

cannot be certain that it will receive regulatory approval or be successfully commercialized, and

2 "We face heavy government regulation, and FDA and international regulatory approval of our

3 products is uncertain. However, the Report did not contain any specific risk warnings regarding the

4 Phase 2 results. Instead, the 10-K included only the following general and generic statement:

5 Our clinical trials may not yield results that will enable us to obtain regulatory approval for our products. 6 We, and our collaborators, will only receive regulatory approval for a drug candidate 7 ifwe can demonstrate in carefully designed and conducted clinical trials that the drug candidate is safe and effective. We do not know whether our current or any future 8 clinical trials will demonstrate sufficient safety and efficacy to obtain the requisite regulatory approvals or will result in marketable products. Clinical trials are lengthy, 9 complex and expensive processes with uncertain results. It will take us several years to complete our testing, and failure can occur at any stage of testing. To date, we 10 have not successfully completed any Phase 3 clinical trials, and we have not completed all planned pre-clinical and Phase 1 clinical trials for each of our product 11 candidates. The results we obtain in pre-clinical testing and early clinical trials may not be predictive of results that are obtained in later studies. We may suffer 12 significant setbacks in advanced clinical trials, even after promising results in earlier studies. Based on results at any stage of clinical trials, we may decide to repeat or 13 redesign a trial or discontinue development ofone or more of our drug candidates. If we fail to adequately demonstrate the safety and efficacy of our products under 14 development, we will not be able to obtain the required regulatory approvals to commercialize our drug candidates, and our business, results of operations and 15 financial condition will be materially adversely affected.

16 135. The Report on Form 10-K was also materially false and misleading to investors

17 because it failed to disclose known risks and uncertainties regarding the comparability ofthe Phase 2

18 results with the Phase 3 trials then being conducted. When considered together with defendants'

19 public statements touting the Phase 2 results and strongly suggesting that the Phase 3 clinical trials

20 would succeed and the drug would be marketable, including the statements alleged in ¶¶92-94,100-

21 101, 107-110, the incomplete risk warnings in the Report on Form 10-K misled investors. Among

22 the risks that were not disclosed to investors were that: (i) in the Phase 2 PAO trial, the blood clot

23 may have simply been broken up by the action of the catheter pushing into the clot, rather than

24 dissolved by the action of the drug, a possibility that had been raised internally at Nuvelo even

25 before the Phase 2 PAO trials were completed; (ii) in the Phase 3 CO trial, Nuvelo had agreed with

26 the FDA to demonstrate success at a statistical significance level that wasforty times more stringent

27 than what the market believed, rendering success much less likely; (iii) the market opportunity for

28 the drug in PAO was much smaller than represented to analysts and the market because of

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -58- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 62 of 79

1 competition from off-label use of other drugs and mechanical clot-busting techniques, the potential

2 impact of which was not timely or accurately disclosed to investors ; and (iv) Nuvelo had an

3 undisclosed "target product profile which would be necessary to meet in order for the Company to

4 market alfimeprase for CO, and the Company would not proceed to market alfimeprase for that

5 indication if the trial results did not meet that profile, even if the drug was otherwise qualified for

6 FDA approval.

7 136. On May 9, 2006, Nuvelo issued its Report on Form 10-Q for the first quarter of 2006,

8 the period ending March 31, 2006, signed by Titus and certified by both Titus and Love pursuant to

9 the Sarbanes-Oxley Act. As the CEO of Nuvelo, Love was responsible, with Titus, for reviewing

10 the Report before it was filed with the SEC and assuring the accuracy of the information reported

11 therein, including that all material known risks were disclosed to the market.

12 137. As with Nuvelo's prior public SEC filings, the I Q06 Report on Form 10-Q included

13 only general and generic risk warnings, such as "Our near-term success is dependent on the success

14 of our lead product candidate, alfimeprase, and we cannot be certain that it will receive regulatory

15 approval or be successfully commercialized, and "We face heavy government regulation, and FDA

16 and international regulatory approval of our products is uncertain. However, the Report did not

17 contain any specific risk warnings regarding the Phase 2 results. Instead, the Report merely repeated

18 the generic, general warnings found in the FY05 Report on Form 10-K, including those quoted

19 above.

20 138. Defendants failed to disclose known risks and uncertainties regarding the

21 comparability of the Phase 2 results with the Phase 3 trials then being conducted. When considered

22 together with defendants' public statements touting the Phase 2 results as strongly suggesting that

23 the Phase 3 clinical trials would be successful, and the drug would be marketable and commercially

24 successful, including the statements alleged in ¶¶92-94,100-101, 107-110, 116, 120, the incomplete

25 risk warnings in the Report on Form 10-Q misled investors.

26 139. On August 8, 2006, Nuvelo issued its Report on Form 10-Q for the second quarter of

27 2006, the period ending June 30, 2006, certified by Love pursuant to the Sarbanes-Oxley Act. As

28 the CEO ofNuvelo, Love was responsible for reviewing the Report before it was filed with the SEC

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -59- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 63 of 79

1 and assuring the accuracy of the information reported therein, including that all material risks were

2 disclosed to the market.

3 140. As with Nuvelo's prior public SEC filings, the 2Q06 Report on Form 10-Q included

4 only general and generic risk warnings, such as "Our near-term success is dependent on the success

5 of our lead product candidate, alfimeprase, and we cannot be certain that it will receive regulatory

6 approval or be successfully commercialized, and "We face heavy government regulation, and FDA

7 and international regulatory approval of our products is uncertain. However, the Report did not

8 contain any specific risk warnings regarding the Phase 2 results. Instead, the Report merely repeated

9 the generic, general warnings found in the FY05 Report on Form 10-K, including those quoted

10 above.

11 141. Defendants failed to disclose known risks and uncertainties regarding the

12 comparability of the Phase 2 results with the Phase 3 trials then being conducted. When considered

13 together with defendants' public statements touting the Phase 2 results as strongly suggesting that

14 the Phase 3 clinical trials would be successful, and the drug would be marketable and commercially

15 successful, including the statements alleged in ¶192-94, 100-101, 107-110, 116, 120, 124-125, the

16 incomplete risk warnings in the Report on Form 10-Q misled investors.

17 142. On November 8, 2006, Nuvelo issued its Report on Form 10-Q for the third quarter of

18 2006, the period ending September 30, 2006, certified by Love pursuant to the Sarbanes-Oxley Act.

19 As the CEO of Nuvelo, Love was responsible for reviewing the Report before it was filed with the

20 SEC and assuring the accuracy of the information reported therein, including that all material risks

21 were disclosed to the market.

22 143. As with Nuvelo's prior public SEC filings, the 3Q06 Report on Form 10-Q included

23 only general and generic risk warnings, such as "Our near-term success is dependent on the success

24 of our lead product candidate, alfimeprase, and we cannot be certain that it will receive regulatory

25 approval or be successfully commercialized, and "We face heavy government regulation, and FDA

26 and international regulatory approval of our products is uncertain. However, the Report did not

1 the generic , general warnings found in the FY05 Report on Form 10-K, including those quoted

2 above.

3 144. Defendants failed to disclose known risks and uncertainties regarding the

4 comparability of the Phase 2 results with the Phase 3 trials then being conducted. When considered

5 together with defendants' public statements touting the Phase 2 results as strongly suggesting that

6 the Phase 3 clinical trials would be successful, and the drug would be marketable and commercially

7 successful, including the statements alleged in ¶192-94, 100-101, 107-110, 116, 120, 124-125, the

8 incomplete risk warnings in the Report on Form 10-Q misled investors.

9 X. ADDITIONAL SCIENTER ALLEGATIONS

10 A. Individual Defendants ' Compensation Was Tied to Financial Performance 11 145. According to defendants' Proxy Statement, filed with the SEC on April 18, 2007, the 12 Individual Defendants' bonus compensation was heavily tied to the Company's financial 13 performance: 14 The Compensation Committee determines each individual executive bonus by 15 reference to the achievement of corporate goals and the individual executive's achievement of functional goals for the functional organization that he or she 16 manages. The Company's Board of Directors sets annual corporate goals that fall into the following categories: ... Strengthening the Company's financial position. 17 Also included among the 2006 goals was the completion of the NAPA-2 and SONOMA-2 Phase 3 18 clinical trials. 19 146. A chart demonstrating the Individual Defendants ' compensation follows . The chart, 20 particularly the bonuses granted to defendants Love and Levy (Titus left the Company before year- 21 end 2006) evidence the apparent emphasis placed on "strengthening the Company's financial 22 position -both Love and Levy received huge 2006 bonuses - Love's was over $100,000 more than 23 it had been in 2005, even though the Company wholly failed to obtain one ofthe explicit 2006 goals 24 of completing the Phase 3 clinical trials for PAO and CO: 25

11 B. Defendants Were Motivated to Commit Fraud to Gain Access to Capital through the Follow-On Offering 12 147. Defendants had motive and opportunity to inflate the price of Nuvelo securities 13 because the Company was desperately in need of cash. By the end of the Company's fiscal year 14 2005, it had less than $38 million in cash and an established track record of using positive 15 announcements about alfimeprase to generate cash. 16 148. As a result of defendants' false statements, Nuvelo's stock traded at inflated levels 17 during the Class Period, trading as high as $20.71 per share in August 2006, and the Company was 18 able to sell $119 million worth of Nuvelo securities in the Follow-On Offering. 19 149. On January 24, 2006, one day after Nuvelo issued its press release entitled "Nuvelo 20 Receives FDA Fast Track Status for Alfimeprase, the Company announced it would conduct the 21 Follow-On Offering. Just as the Company had done since at least 2003, the Company again 22 leveraged the buildup it created around alfimeprase, only this time through false and misleading 23 statements, as a tool for raising much needed cash to continue business and fund the exorbitant pay 24 packages provided to insiders. Defendants' false and misleading statements about alfimeprase 25 allowed it to complete the sale of 7.475 million shares at $16 per share for proceeds, before 26

27 9 Levy joined the Company in November 2004. 28

1 deducting underwriting discounts and offering expenses, ofapproximately $119.6 million on January

2 30, 2006.

3 150. To convince investors ofthe potential for alfimeprase, defendants repeatedly claimed

4 that the CO and PAO trials were just the first step in commercial development ofthe drug, and other

5 treatments , with potentially larger patient populations, were also in the offing. For example, in its

6 Registration Statement and Prospectus for the January 2006 Follow-on Offering and its Report on

7 10-K for fiscal year 2005, issued March 15, 2006, Nuvelo stated:

8 Our lead cardiovascular development program is for alfimeprase, a novel, direct- acting thrombolytic agent, or blood clot dissolver, which is currently in Phase 3 9 clinical trials for the treatment of acute peripheral arterial occlusion, or PAO, and for the treatment of catheter occlusion. We also intend to expand this development 10 program by initiating a Phase 2 clinical trial in the second halfof2006 to evaluate thepotential ofalfcmeprasefor the treatment ofischemic stroke and another Phase 11 2 clinical trial in 2007 to evaluate thepotential ofalfimeprase to treat deep venous thrombosis, or DVT. 12 151. The Company' s Registration Statement and Prospectus filed in connection with the 13 January 30, 2006 offering described the ongoing alfimeprase clinical testing and provided a chart 14 purporting to depict the Company's drug pipeline and the anticipated commercialization of 15 alfimeprase: 16

25 152. Nuvelo never initiated the planned Phase 2 clinical trial for the treatment ofischemic 26 stroke, even though it was supposed to begin before Phase 3 results for either the PAO or CO trials 27 were completed. This suggests that defendants were aware that the Phase 2 results were not 28

1 predictive of success in Phase 3, and defendants were not confident that PAO and CO were "low

2 risk paths to regulatory approval or would be "rapid to market, well before the failure ofthe Phase

3 3 study was publicly announced on December 11, 2006.

4 XI. PRESUMPTION OF RELIANCE AND PROXIMATE LOSS CAUSATION/ECONOMIC LOSS 5 153. Plaintiffs' claims for securities fraud are asserted under the fraud on the market theory 6 of reliance. The market price of Nuvelo's securities, including common stock regularly traded on 7 the NASDAQ market and options regularly traded on AMEX, CBOE, PHLX, ISE and PSE, was 8 artificially inflated by the false and misleading statements complained of herein, including 9 defendants' false statements regarding the results of the Phase 2 trials of alfimeprase, the 10 comparability of those results to the expected results from ongoing Phase 3 clinical trials of 11 alfimeprase, the likelihood ofFDA approval, the marketability and commercial potential ofthe drug 12 and the omission ofmeaningful warnings about those risks. These false statements inflated the price 13 of Nuvelo's stock, causing injury to investors when that inflation was eliminated as the risks and 14 conditions hidden by defendants' fraudulent scheme were revealed on December 11, 2006 and the 15 market learned that the Phase 3 trials had failed: 16

1 Had defendants corrected their false statements and made meaningful disclosure ofthe risks prior to

2 or during the Class Period, Nuvelo's securities would not have traded as high as they did during the

3 Class Period, or would have declined sooner than they did following the end of the Class Period.

4 A. Applicability of Presumption of Reliance: Fraud on the Market Doctrine 5 154. At all relevant times, the market for Nuvelo 's securities was an efficient market for 6 the following reasons, among others: 7 (a) Nuvelo's security met the requirements for listing, and was listed and actively 8 traded on the NASDAQ market, a highly efficient and automated market; 9 (b) Nuvelo's options met the requirements for listing and were listed and actively 10 traded on the AMEX, CBOE, PHLX, ISE and PSE, highly efficient and automated markets; 11 (c) As a regulated issuer, Nuvelo filed periodic public reports with the SEC and 12 NASDAQ; 13 (d) Nuvelo regularly communicated with public investors via established market 14 communication mechanisms, including through regular disseminations of press releases on the 15 national circuits ofmajor newswire services, publications on its website and other Internet sites, and 16 through other wide-ranging public disclosures, such as through conference calls, communications 17 with the financial press and other similar reporting services; and 18 (e) Nuvelo was followed by securities analysts employed by 15 major brokerage 19 firms, including Deutsche Bank; Prudential; Brean Murray; CIBC World Markets; Oppenheimer; 20 Needham; Pacific Growth Equities; Piper Jaffray & Co.; Miller Johnson; Banc of America; UBS; 21 Morgan Joseph; JP Morgan; Wachovia and William Blair & Company, each of which regularly 22 wrote reports which were distributed to the sales force and certain customers of their respective 23 brokerage firms. Each of these reports was publicly available and entered the public marketplace. 24 155. As a result of the foregoing, the market for Nuvelo' s securities promptly digested 25 current information regarding Nuvelo from all publicly-available sources and reflected such 26 information as Nuvelo's securities price. Under these circumstances, all purchasers of Nuvelo's 27 securities during the Class Period suffered similar injury through their purchase of Nuvelo's 28

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -65- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 69 of 79

1 securities at artificially inflated prices and their subsequent decline in value, thus a presumption of

2 reliance applies.

3 B. Defendants' False and Misleading Statements Proximately Caused Economic Loss to Nuvelo's Investors 4 156. On January 5, 2006, the first day of the Class Period, Nuvelo announced that it had 5 convinced Bayer to fund further clinical trials of alfimeprase, which the market viewed as an 6 endorsement of defendants ' prior statements regarding the Phase 2 results and the commercial 7 potential of alfimeprase, causing Nuvelo's stock price to skyrocket on elevated trading volume of 8 10,075, 500 shares , more than 17 times its daily average . Supra ¶72. Nuvelo's stock increased from 9 $9.01 to close at $12 . 67, a one day gain of more than 40%. By comparison, the NASDAQ 10 Biotechnology Index ("NBI ), of which Nuvelo is a member, rose a modest 0.55% that day. 11 Nuvelo's stock price continued to increase over the next three days as the market digested and 12 reacted to this news , closing at $ 15.62 per share on January 10, 2006 - an additional gain of 20% in 13 value on continued elevated trading volumes in excess of 26 million shares per day. By comparison, 14 the NBI gained a modest 3 . 18% during the same time period. 15 157. During the Class Period, defendants maintained the artificial inflation in Nuvelo's 16 securities prices by continuing to make false and misleading statements regarding the anticipated 17 results of the Phase 3 clinical trials of alfimeprase, the extent to which the reported results of the 18 Phase 2 trials were a reliable indicator ofboth the positive action of alfimeprase in dissolving blood 19 clots and catheter occlusions, the likelihood of similar results being achieved in the Phase 3 trials, 20 the "low risk and "rapid path to FDA approval and the marketability and commercial potential of 21 alfimeprase. But for defendants' failure to meaningfully disclose the known risks in its periodic 22 filings with the SEC or their false and misleading statements, Nuvelo's securities would not have 23 traded at the elevated levels they did during the Class Period. 24 158. The inflation in Nuvelo's securities prices was eliminated when the market learned 25 that, contrary to defendants' statements during and even prior to the Class Period, alfimeprase had 26 not worked as represented in the Phase 2 trials, that the Phase 3 trials had failed as a result of risks 27 that had been concealed or downplayed by defendants in a manner that misled investors during the 28

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -66- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 70 of 79

Class Period, that the drug did not meet the Company's target product profile necessary to market it

2 for CO, and the FDA had imposed an extraordinary high standard for approval of the drug for CO.

3 Most ofthis inflation was eliminated when Nuvelo announced, on December 11, 2006 - the last day

4 of the Class Period - that alfimeprase had failed the Phase 3 clinical trials, causing Nuvelo's stock

5 price to plummet. Nuvelo's share price fell from $19.55 to close at $4.05, a one day drop of nearly

6 80% on extraordinary trading volume of 90,150,600 shares - more than 150 times its daily average,

7 causing injury to investors who purchased at the fraud-inflated prices prevailing in the market during

8 the Class Period. By comparison, the NBI experienced a modest drop of 0.6% that day.

9 159. The remaining inflation was eliminated on June 27, 2007, when Bayer pulled out of

10 further efforts to develop alfimeprase and defendants revealed the full extent by which the risks of

11 failure in the Phase 3 trials had been withheld from investors, causing additional injury to Class

12 members who continued to hold their securities through the date of that announcement. Nuvelo's

13 stock dropped from $3.34 to $2.73 that day on elevated trading volume of 6,930,900 shares, a one-

14 day decline of more than 18%. By comparison, the NBI increased 1.93% on the same day.

15 160. The foregoing allegations describe plaintiffs ' general theory ofdamages, demonstrate

16 that plaintiffs' damages were caused by the scheme to defraud as alleged herein, and negate any

17 inference that plaintiffs' losses were the result of general market conditions or other factors wholly

18 unrelated to the false and misleading information complained ofherein. Upon further investigation

19 and expert analysis, plaintiffs may assert that there were additional inflationary or corrective events

20 that caused or contributed to the damages they incurred.

21 XII. GROUP PLEADING ALLEGATIONS

22 161. Because of their senior executive and managerial positions with Nuvelo and, in the

23 case ofLove, his position as Chairman ofNuvelo's board of directors, the Individual Defendants had

24 access to the adverse undisclosed information described herein regarding the Company's business

25 operations and present and future business prospects. The Individual Defendants obtained such

26 information through internal corporate documents and communications with other corporate officers

27 and employees, attendance at management and board of directors meetings and committees thereof

28 and through reports and other information provided to them in connection therewith. The Individual

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -67- 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 71 of 79

1 Defendants knew or recklessly disregarded that said adverse information had not been disclosed to,

2 and was being concealed from, the investing public.

3 162. It is appropriate to treat the Individual Defendants as a group for pleading purposes

4 and to presume that the false, misleading and incomplete information contained in the Company's

5 public filings, press releases and other publications as alleged herein are the collective actions ofthe

6 narrowly defined group of Individual Defendants. Each of the above officers and/or directors of

7 Nuvelo, by virtue of their high-level positions with the Company, directly participated in the

8 management ofthe Company, was directly involved in the day-to-day operations ofthe Company at

9 the highest levels and was privy to confidential proprietary information concerning the Company and

10 its business operations and present and future business prospects, as alleged herein. Said defendants

11 were involved in drafting, producing, reviewing and/or disseminating the false and misleading

12 statements and information alleged herein, were aware of or deliberately disregarded that the false

13 and misleading statements were being issued regarding the Company, and approved or ratified these

14 statements, in violation of the federal securities laws.

15 163. As officers and/or directors and controlling persons of a publicly held company

16 whose common stock was, and is, registered with the SEC pursuant to the Exchange Act, traded on

17 the NASDAQ, and whose options were registered and traded publicly on five options exchanges,

18 and governed by the provisions of the federal securities laws, the Individual Defendants each had a

19 duty to disseminate promptly accurate and truthful information with respect to the Company's

20 business operations and present and future business prospects , and to correct any previously issued

21 statement that had become materially misleading or untrue, so that the market price of the

22 Company's securities would be based upon truthful and accurate information. The Individual

23 Defendants ' misrepresentations and omissions during the Class Period violated these specific

24 requirements and obligations.

25 164. Each of the defendants is liable as a direct participant with respect to the wrongs

26 complained of herein. In addition, the Individual Defendants, by reason of their status as senior

27 officers and/or directors, were "controlling persons within the meaning of §20 ofthe Exchange Act,

28 and had the power and influence to cause the Company to engage in the unlawful conduct

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -68- C se 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 72 of 79

1 complained ofherein. Because of their positions of control, the Individual Defendants were able to

2 and did, directly or indirectly, control the conduct of Nuvelo's business.

3 165. The Individual Defendants, because oftheir positions with the Company, controlled

4 and/or possessed the authority to control the contents of Nuvelo's reports, press releases and

5 presentations to securities analysts, money and portfolio managers and institutional investors, i.e.,

6 the market. Each of the Individual Defendants was provided with copies of the Company's reports

7 and press releases alleged herein to be misleading, prior to or shortly after their issuance and had the

8 ability and opportunity to prevent their issuance or cause them to be corrected. Thus, each of the

9 Individual Defendants had the opportunity to commit the fraudulent acts alleged herein.

10 XIII. CLASS ACTION ALLEGATIONS

11 166. Plaintiffs bring this action as a class action pursuant to Fed. R. Civ. P. 23(a) and

12 (b)(3) on behalf of a class consisting of all persons who purchased the Company's publicly traded 13 securities on the open market or in a registered stock offering during the period January 5, 2006 14 through December 8, 2006, inclusive, and who were damaged thereby (the "Class ). Excluded from 15 the Class are defendants, the Company's officers and directors, affiliates, legal representatives, heirs, 16 predecessors, successors and assigns, and any entity in which the Company has a controlling interest 17 18 or of which the Company is a parent or subsidiary.

19 167. The members of the Class are located in geographically diverse areas and are so

20 numerous that joinder of all members is impracticable. The disposition of their claims in a class 21 action will provide substantial benefits to the parties and the Court. Nuvelo had approximately 53 22 million shares of its common stock outstanding and active options trading. 23 168. Common questions of law or fact exist as to all members of the Class and 24

25 predominate over any questions affecting solely individual members of the Class. Among the

26 questions of law or fact common to the Class are:

27 (a) Whether the Exchange Act was violated by defendants;

28 (b) Whether defendants omitted and/or misrepresented material facts;

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -69- C se 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 73 of 79

1 (c) Whether defendants' statements omitted material facts necessary to make the

2 statements made, in light of the circumstances under which they were made, not misleading;

3 (d) Whether defendants knew or deliberately disregarded that their statements

4 were false and misleading;

5 (e) Whether the prices of Nuvelo publicly traded securities were artificially

6 inflated; and

7 (f) The extent of damage sustained by Class members and the appropriate

8 measure of damages.

9 169. Plaintiffs' claims are typical of the claims of the members of the Class as plaintiffs

10 and members of the Class sustained damages arising out of defendants' wrongful conduct in 11 violation of federal laws as complained of herein. 12 170. Plaintiffs will fairly and adequately protect the interests ofthe members ofthe Class 13 and have retained counsel competent and experienced in class action and securities litigation. 14 Plaintiffs have no interests antagonistic to or in conflict with those of the Class. 15

16 171. A class action is superior to other available methods for the fair and efficient

17 adjudication of this controversy since joinder of all members of the Class is impracticable.

18 Furthermore, because the damages suffered by individual Class members may be relatively small, 19 the expense and burden of individual litigation make it impossible for the Class members 20 individually to redress the wrongs done to them. There will be no difficulty in the management of 21 this action as a class action. 22

23 FIRST CLAIM FOR RELIEF

24 For Violation of Section 10(b) of the Exchange Act and Rule lOb-5 Against All Defendants 25 172. Plaintiffs incorporate all prior allegations of the Complaint herein by reference. 26 173. During the Class Period, defendants disseminated or approved the false statements 27 specified above, which they knew or recklessly disregarded were materially false and misleading in 28

CONSOLIDATED COMPLAINT FOR VIOLATIONS OF THE FEDERAL SECURITIES LAWS - 3:07-cv-04056-MMJ -70- C se 3:07-cv-04056-VRW Document 31 Filed 11/09/2007 Page 74 of 79

1 that they contained material misrepresentations and failed to disclose material facts necessary in

2 order to make the statements made, in light of the circumstances under which they were made, not

3 misleading. 4 174. Defendants violated § 10(b) of the Exchange Act and Rule I Ob-5 in that they: 5 (a) Employed devices, schemes and artifices to defraud; 6 (b) Made untrue statements of material facts or omitted to state material facts

necessary in order to make the statements made, in light ofthe circumstances under which they were 8 made, not misleading; or 9 (c) Engaged in acts, practices and a course ofbusiness that operated as a fraud or 10 deceit upon plaintiffs and others similarly situated in connection with their purchases of Nuvelo 1 1 securities during the Class Period. 12 175. As a result of the dissemination of the materially false and misleading information 13 and failure to disclose material facts, as set forth above, the market price ofNuvelo's publicly traded 14

15 securities was artificially inflated during the Class Period. In ignorance of the fact that the market

16 price ofNuvelo's publicly traded securities was artificially inflated, and relying directly or indirectly

17 on the false and misleading statements made by defendants, or upon the integrity of the market in 18 which the securities trade, and/or on the absence of material adverse information that was known to 19 or recklessly disregarded by defendants but not disclosed in public statements by defendants during 20 the Class Period, plaintiffs and the other members ofthe Class acquired Nuvelo securities during the 21

22 Class Period at artificially high prices and were damaged thereby as demonstrated, in part, by the

23 declines in the price of Nuvelo's securities following the revelation of the relevant truth to the

24 market. 25 176. As a direct and proximate result of defendants' wrongful conduct, plaintiffs and the 26 other members ofthe Class suffered damages in connection with their purchases ofNuvelo securities 27 during the Class Period. 28

1 SECOND CLAIM FOR RELIEF

2 For Violation of Section 20(a) of the Exchange Act Against All Defendants 3 177. Plaintiffs incorporate all prior allegations of the Complaint herein by reference. 4 178. The Individual Defendants acted as controlling persons ofNuvelo within the meaning 5

6 of §20(a) ofthe Exchange Act. By reason oftheir positions as officers and/or directors ofNuvelo, and

7 their ownership of Nuvelo stock, the Individual Defendants had the power and authority to cause

8 Nuvelo to engage in the wrongful conduct complained of herein. Nuvelo controlled each of the 9 Individual Defendants and all ofits employees. By reason of such conduct, the Individual Defendants 10 and Nuvelo are liable pursuant to §20(a) of the Exchange Act. 11 PRAYER FOR RELIEF 12 WHEREFORE, plaintiffs pray for judgment as follows: 13 A. Declaring this action to be a proper class action pursuant to Rule 23 of the Federal 14 Rules of Civil Procedure; 15

16 B. Awarding plaintiffs and the members of the Class damages , including interest;

17 C. Awarding plaintiffs and the members reasonable attorneys' fees, expert witness fees

18 and other costs; and 19 D. Awarding such equitable and/or injunctive or other relief as the Court may deem just 20 and proper. 21 JURY DEMAND 22 Plaintiffs demand a trial by jury. 23 DATED: November 9, 2007 COUGHLIN STOIA GELLER 24 RUDMAN & ROBBINS LLP DENNIS J. HERMAN 25 MONIQUE C. WINKLER 26

CERTIFICATION OF NAMED PLAINTIFF

I. Juan Pablo Cabrera, hereby certify that the following is true and correct to the best of my knowledge, information and belief:

I have reviewed the complaint (the "Complaint") and would be willing to serve as a lead plaintiff on behalf of the class (the "Class") as defined in the Complaint, including providing testimony at deposition and trial, if necessary..
