As a humorous point/observation, we find the titles of the two Biogen sponsored symposium to be held at ECTRIMS very interesting: 10/2 17.15 “Biogen Idec: Reinventing MS care – Evolution” and 10/3 07.45 “Biogen Idec: Reinventing MS care – Revolution”. Umm, we wonder where they got that inspiration from…

Slide 3 September 2013 ECTRIMS 2013: It’s a Revolution! – But Just How Big?

. In our view, it’s not a question of whether it is a revolution or evolution anymore; the MS market IS undergoing a revolution! . The question is now just how big a revolution (and for investors what is not priced into the stocks!) . This revolution in the clinical management of MS is being driven not only by the launch of next-gen agents but also by changing treatment and diagnosis paradigms. . The consequence of this revolution is that MS is rapidly changing from a “diagnose, treat, and see” to a “treat aggressively to the goal” therapeutic area. . The upcoming ECTRIMS meeting (Copenhagen Oct 2-5), will deliver incremental clinical data (rather than key pivotal data) for next-gen MS agents. . More importantly, the meeting will act as an important “front-line forum” to gauge the massively changing dynamics within the MS therapeutic area. . Within this pre-pack, we provide (1) An itinerary planner for the meeting arranged by “must attend”, “day-by-day” and “MS Therapy” (2) A MS market overview and (3) Next-Gen agent profiles Sources: Company data, Credit Suisse analysis Slide 4 September 2013 Our top-10 sound bites/observation/questions/focal points for the conference(cont.) . (1) “Warehoused” untreated MS population remains an important sensitivity. . (2) Earlier and “treat-to-goal” like management to drive a dynamic market. . (3) Increasing focus on MRI clinical measures in diagnosis and treatment . (4) Is our “three buckets hypothesis” still valid? . (5) Is price of drugs influencing treatment choices? . (6) What is interesting in the earlier stage development pipeline? . (7) How do physicians view the relative clinical efficacy of MS therapeutics? . (8) How will the treatment sequencing change? . (9) What is the emerging side effect profile of Tecfidera? (especially (a) Is PML a real gating point concern?; (b) What is the real world flush/GI impact?) . (10) How do physicians view Tecfidera leukocyte and lymphocyte monitoring?

Key Points to Our 3 Bucket Thesis: (1) We view MS therapeutics in 3 broad buckets: Two established buckets (i) ABCR and (ii) High-Efficacy/Second-Line agents and an emerging new class of products that we call (iii) Oral agents (2) The overall MS market is still dominated (~80% market share by value) by ABCRs (despite their relative modest efficacy and less than ideal side effect profile) as they are the only alternatives to High-Efficacy/Second-Line agents (~20% market share by value) and their associated serious infections concerns (3) Tecfidera is the leading Oral, showing efficacy above ABCRs/near High-Efficacy/Second-Line AND possessing a better safety profile than High-Efficacy/Second-Line (and ABCRs). In our view this will allow significant market share in new patients, but also propagate significant switching from ABCRs (4) RPC1063 is an S1P1 modulator, within the same class as Gilenya. In our view, the totality of RCP1063’s clinical profile, notably improved half-life/fast recovery of lymphocytes and improved cardiotoxicity/hepatoxicity over Gilenya could effectively position RCP1063 in a different bucket relative to Gilenya

Multiple Sclerosis - Addressing PML head on – July 31 2013 Bottom Line: PML is clearly a primary concern in the MS community. The note addressed two events related to PML have occurred over the last two weeks – 3rd PML case in Gilenya taking patient and BIIB prepping street for PML concerns for patients on Tecfidera . We retain our view (and much more importantly gauge that the majority of physicians views are) that neither Gilenya / (or any S1P1s) nor Tecfidera mechanistically contribute to PML occurrence. [Full Note]

BIIB: There is no easy answer - 160 and counting – Jun 12 2013 Bottom Line: We go over the real issues on Tecfidera receiving regulatory data protection (RDP) in the EU. Key points: - Exclusivity can be garnered via the “New Active Substance” or “Independent Development principle” pathway. BIIB is attempting to go via the “Independent Development principle” pathway. - Regulatory protection is separate and independent from patent protection. The lack of regulatory protection should not have any impact on the patents. - We strongly reiterate that the ‘065 patent is key and that it DOES provide protection until October 2019. - We made no changes to our modeling assumptions (which never included RDP) - Focus on the TRx market share - The level/impact of pent-up demand from “warehoused” patients is a much more important consideration than raw NRx numbers of different sample packs! [Full Note]

Not Necessarily a Storm in a Tea Cup – May 30 2013 Bottom Line: When the dust settles on BIIB’s decision to delay EMA approval of Tecfidera to secure regulatory data protection (RDP), there are two main scenarios, and we still see more overall upside risk than downside risk. [Full Note]

Slide 12 September 2013 Previously published CS MS Notes – Directly Tecfidera Related (cont.)

“NEJM Articles on PML in Patients Treated with Fum aric Acid – 2nd Opinion” – Apr 25 2013 Bottom Line: Feedback on NEJM articles in which we highlighted that we were still Tecfidera bulls (with risk on the upside for estimates) but also flagging that to completely ignore the NEJM articles would be overly dismissive. [Full Note]

“NEJM Articles on PML in Patients Treated with Fum aric Acid – Opinion” – Apr 24 2013 Bottom Line: Key take-homes from the NEJM articles and BIIB’s response, in our first-glance view, are: (a) 2 of the 4 patients had severe lymphopenia for 2-5 years before diagnosis of PML, the other two patients has significant compounding factors (treatment with methotrexate and ); (b) Much of the focus of the articles is on the lymphopenia issues. [Full Note]

The price of today's sushi is reasonable – Apr 1 2013 Bottom Line: U.S. Tecfidera pricing is in-line with expectations: The U.S. pricing of Tecfidera became available on Friday (post the FDA approval on 03/27/13); Tecfidera’s wholesale acquisition cost (WAC) is $54.9K per year, a slight premium to average ABCR pricing ($52.5K per year), but at a notable discount to Gilenya’s pricing ($60.4k per year). We strongly reiterate our view that the launch trajectory of Tecfidera is not only important for BIIB stock (obviously!) but also for the large-cap biotech sector in general. [Full Note]

So let's find out if this is actually a revolution or evolution: "warehousing" could drive near term upside – Mar 27 2013 Bottom Line: FDA announced that it had approved Tecfidera for the treatment of relapsing remitting multiple sclerosis (RRMS) and Tecfidera’s label was made available. The focus now shifts to the Tecfidera ramp. Pricing (and post marketing requirements) are expected to be disclosed within the next day or so. We re-highlight that warehousing ahead of Tecfidera’s launch could provide upside to near-term estimates. [Full Note]

Positive CHMP opinion for Tecfidera and Aubagio – Mar 22 2013 Bottom Line: BIIB’s Tecfidera (BG-12) and Sanofi’s Aubagio (Teriflunomide) received a positive CHMP opinion today. We reiterate our view that Tecfidera’s higher efficacy and overall better profile positions this drug as the key NIMO agent. [Full Note]

Slide 13 September 2013 Previously published CS MS Notes – Directly Tecfidera Related (cont.)

Synaplin (BG12) remains a NIMO based on putative labeling information – Jan 17 2013 Bottom Line: Putative Synaplin label raises no major surprises. Examination of temporarily publically-available beta websites for Synaplin (BG- 12), and concomitant comparison of the indication and safety information to currently marketed MS agents raise no major surprises and in essence places Synaplin’s label on an even playing field. MS therapeutic success has historically not been about the label per se; the commercial battle remains focused on marketing, messaging, and positioning. [Full Note]

Synaplin (BG-12) Citizen Petition Filed – Jan 10 2013 Bottom Line: TEVA’s CP is unlikely to delay FDA’s approval of BG-12, which we still assume takes place in late September 2013. Of the three statements in the CP, the second one regarding safety issues identified in MS therapies after FDA approval (Tysabri, Gilenya) is the most important. [Full Note]

BG-12's 3-month delay; it's not that unusual – Oct 18 2012 Bottom Line: We strongly believe that there is no significant clinical reason. We base this conclusion on the fact that: (1) we have already seen the granularity of DEFINE and CONFIRM (NEJM, AAN, ECTRIMS). (2) Physician excitement for BG-12 remains high, following our channel checks at the latest ECTRIMS. [Full Note]

BG12 Patent Update - NIMO Is Refusing To Sit On The Couch – May 22 2012 Bottom Line: An update of our original deep-dive BG12 patent analysis first published in June 2011. Over the last 12 months, the clinical profile of BG12 has become much clearer with DEFINE and CONFIRM datasets. We think the debate on BG12’s IP will intensify over the next 12 months and note that the ultimate IP protection of BG12 will have significant impact on all players within the MS space [Full Note]

Previously published CS MS Notes – Evolution/Revolution

NOTE: Please right click “Full Note” and click “Open Hyperlink” to access the Full Note.

It's a Revolution! – Just How Big? – Adapting our CS NIMO/3-bucket thesis – Sept 13 2013 Bottom Line: In this note, we discuss and adapt our NIMO/3-bucket thesis on the basis of Tecfidera and Aubagio's PIII data and launches as well as significant physician and company feedback. The key subtle changes in our new adaptation are: (1) "NIMO" bucket = "Oral" bucket. (2) “Immuno-suppressives” = “High-Efficacy/2nd-Line”. [Full Note]

It's a Revolution! – Just How Big? – Driving Market Growth: Past, Present & Future – Sept 11 2013 Bottom Line: The MS market has grown massively over the last 10 years – patient numbers doubled, but value quadrupled. [Full Note]

Evolution or Revolution - Tecfidera Rx numbers - What it all means – May 23 2013 Bottom Line: Lots of “noise” in NRx data, nevertheless TRx data suggests significant upside to 2013 and 2014 Tecfidera numbers. The extrapolation of Rx numbers just 6 weeks into launch to Q2’13 or FY’13 numbers could be highly inaccurate in our view. [Full Note]

Evolution or Revolution – “The first harvest for Tecfidera - How big is the warehouse?’” – Apr 11 2013 Bottom Line: Within this note we further expand our thesis that there is pent-up, near-term demand for Tecfidera from “warehoused patients”. Specifically, we describe 3 distinct populations of warehoused patients: ‘Anticipatory”, “Switch”, and “Historical”. [Full Note]

Evolution or Revolution – AAN Meeting - The winners and losers in the revolution – Mar 18 2013 Bottom Line: We project that the global MS market could grow from $14.1B in 2012 to $19.2B in 2019, driven by the launch of next-gen agents and changing diagnosis and treatment paradigms. We reiterate our view that this AAN Meeting is about “market dynamics over data.” The consequence is that MS is rapidly changing from a “diagnose, treat, and see” to a “treat aggressively to the goal” therapeutic area. [Full Note]

Slide 15 September 2013 Previously published CS MS Notes – Evolution/Revolution (Cont.)

Evolution or Revolution: Observations about Tecfidera's possible efficacy label claims – Mar 15 2013 Bottom Line: Tecfidera is set to be the biggest drug in the MS market. Tecfidera’s CONFIRM was the first to use Copaxone as the active comparator. In our eyes Tecfidera’s efficacy sits in between ABCR’s and Immunosuppressive’s from our recent channel checks is that many physicians consider Tecfidera to have efficacy that is comparable to Gilenya’s. [Full Note]

Evolution or Revolution – NIMO's don't like to be labeled – Mar 1 2013 Bottom Line: Within this note, we summarize the Warnings & Precautions (W&P) language for all MS drugs. “Innocuous" leukocyte/lymphocyte monitoring recommendations is common on MS drug labels. Tecfidera’s effect on leukocyte/lymphocyte counts are well- defined from PIII studies and warrants similar "innocuous" label wording. [Full Note]

Evolution or Revolution – Tecfidera launch ramp detailed analysis – Feb 6 2013 Bottom Line: In our view, Tecfidera’s ramp should significantly beat Gilenya’s based on our NIMO/3 buckets hypothesis. BIIB remains our key pick in the large cap space based on our four-point perfect storm thesis. We focus on: (1) First-principles, patient-number/ share modeling; (2) Phased EU launch based on recent BIIB guidance and EU drug launches; (3) Comparison of Tecfidera’s launch to Gilenya’s. [Full Note]

Evolution or Revolution – MS 2.0 - Next-gens driving revolution or evolution? – Oct 8 2012 Bottom Line: The MS market is set to undergo significant changes over the coming years due to the introduction of a plethora of “next-gen” or “2.0” new MS therapies. Five key observations: (1) Global MS Market – a highly penetrated market but still significant potential for next-gen agents (2) US vs. ROW – Differential pricing dynamics a key sensitivity (3) “Warehoused” untreated MS population = a very significant opportunity for next-gen agents (4) Switching dynamics are important especially from ABCRs. (5) The NIMO effect: BG12 2018 sales estimated upgraded [Full Note]

Revolution over Evolution: ECTRIMS 2013 – It's a Revolution! – But Just How Big? – Sep 09 2013 Bottom Line: The upcoming ECTRIMS meeting (Copenhagen Oct 2-5) will deliver incremental clinical data (rather than key pivotal data) for next- gen MS agents. Within this note, we include a detailed ECTRIMS planner. [Full Note]

Credit Suisse 5th Annual Therapeutics Day - Key Takeaways – May 13 2013 Bottom Line: We held our 5th Annual Therapeutics Day with expert physician panels covering 5 therapeutic areas. Will the MS marketplace go through an evolution or revolution? Our panelists said Revolution! Is Tecfidera really the winner in the revolution? Our experts said yes, but there are others as well, esp. Gilenya and Tysabri. Are there any other rebels out there? Our panelists were notably positive on Lemtrada and 2nd generation S1P1’s. [Full Note]

Credit Suisse 5th Annual Therapeutics Day: MS Panel “Evolution or Revolution”– May 9 2013 [Full Note]

AAN 2013 - Plegridy: PIII ADVANCE granularity released – Mar 21 2013 Bottom Line: BIIB provided additional PIII ADVANCE data for twice-monthly (Q2W) and once-monthly (Q4W) Plegridy (Pegylated Avonex). Plegridy Q4W though still looks better than “standard” Avonex. While physicians would have preferred once-monthly dosing, Plegridy Q2W still provides the best dosing convenience of all interferons. Elevated transaminases for Plegridy Q2W and Q4W were not overly concerning. Plegridy could grow BIIB’s overall share of the ABCR market. [Full Note]

AAN 2013 - Tecfidera: Warehousing on the upside – Mar 20 2013 Bottom Line: One of the most consistent themes coming out of our channel checks with physicians at the AAN Meeting is the concept of warehousing patients in anticipation of Tecfidera’s launch. Warehousing has been occurring in MS for some time now. This population includes patients who were (1) previously treated, but currently untreated, and (2) diagnosed and currently untreated. [Full Note]

Slide 17 September 2013 Previously published CS MS Notes – AAN/ECTRIMS/CS Therapeutics Day Related (Cont.)

AAN 2013 - Summary of Poster Information – Mar 19 2013 Bottom Line: Posters for the AAN 2013 Meeting were made available yesterday, post market close. In our preview, we had flagged 200+ presentations and posters focused on MS therapies. In this note, we provide some of the takeaways from the key posters [Full Note]

AAN 2013 - RCC - Really! Clarifying chatter on ENDORSE malignancies - nothing new – Mar 18 2013 Bottom Line: We reiterate our conclusions that malignancies in this study (including RCC) were not an issue and that investigators had noted that there was no evidence of increased risk of malignancies in patients treated with Tecfidera. There were “no specific patterns of malignancies or type”, and there was no evidence of increased risk of renal adverse events associated with Tecfidera. [Full Note]

AAN 2013 planner - Market dynamics over data – Mar 1 2013 Bottom Line: The 65th AAN Meeting will deliver incremental clinical data (rather than key pivotal data) for next-gen MS agents. The consequence of this revolution is that MS is rapidly changing from a “diagnose, treat, and see” to a “treat aggressively to the goal” therapeutic area. [Full Note]

Tysabri restructuring: 3 bucket hypothesis = upside to operational leverage AND revenues – Feb 8 2013 Bottom Line: We view the restructuring of BIIB's collaboration on Tysabri with ELN as a significant positive. We see potential not just from an operational gearing perspective, but also a revenues point of view for every drug within BIIB’s MS franchise. The key aspects of our “3 buckets” thesis are potential for long-term SG&A operational gearing and revenue increases of all MS drugs. In our view, over time, we could see consolidation towards one sales-force with a message that effectively states “We are THE MS company. We have the best drug in each segment”. [Full Note]

ECTRIMS 2012 - Spotlight on next-gen S1P1 m odulators – Oct 15 2012 Bottom Line: The most interesting aspect was the incremental data on the next-gen S1P modulators from Actelion, Ono / Merck Serono, Novartis, and Receptos. To differentiate relative to Gilenya, we believe next-gen S1P1s will likely need to improve upon two major deficiencies: (1) CV side effects (2) Reducing time needed to return to normal lymphocyte counts by reducing half-life. Our key take-aways on the S1P1 modulators are included within. [Full Note]

ECTRIMS 2012 - Day Du - BG-12: Additional data supports clinical profile – Oct 12 2012 Bottom Line: Our key take-homes on BG-12 are: (1) Integrated analysis confirms BG-12’s efficacy. (2) Details of integrated analysis affirms BG-12’s safety. (3) Malignancies are NOT an issue. (4) Further evidence of BG-12’s neuro-protective properties. [Full Note]

ECTRIMS 2012 - Day Un: Granularity and support for our warehoused patient hypothesis – Oct 11 2012 Bottom Line: We got some very interesting granularity on this topic at ECTRIMS, supporting our hypothesis that this population could be a significant one for next-gen agents: (i) There is a debate about treating at very first symptoms because of life-long commitment to therapy, in which (especially for ABCRs)…(ii)…adherence is a big challenge with real-world 4-year discontinuation rates of 27-30%; most drop outs occur in the first year, with most NOT going back on therapy. (iii) Even in patients that persist with treatment, physicians estimate that <45% take the proper prescribed dose. [Full Note]

ECTRIMS 2012 Prep Pack – Oct 8 2012 Bottom Line: ECTRIMS meeting will be an important forum providing: 1) incremental clinical data for all agents as described below, 2) premarket messaging, in particular for Sanofi’s (OK technically Genzyme’s) Aubagio (approved 9/12/2012) and Alemtuzumab (PDUFA, Q2’13), and BIIB’s BG-12 (PDUFA, 12/28/2012), and 3) we also flag S1P1 modulators as potential game changers [Full Note]

ECTRIMS 2012: Appetizers are available now – Sept 25 2012 Bottom Line: Within this note, we include a detailed ECTRIMS planner. Full abstracts became available at 6pm EDT. [Full Note]

Global Biotechnology and Pharmaceuticals - ECTRIMS 2012: NIMO et Amis Go Gastronomic – Aug 17 2012 Bottom Line: Titles of the presentations and abstracts became available this week and are detailed in this note. [Full Note]

Slide 19 September 2013 Previously published CS MS Notes – Receptos (RCPT)

NOTE: Please right click “Full Note” and click “Open Hyperlink” to access the Full Note.

Receptos – A Potential Revolutionary Candidate – Development timelines for pipeline are intact – Aug 08 2013 Bottom Line: Focus remains on RPC1063 in Relapsing Multiple Sclerosis (RMS). RCPT is not an earnings-driven story. RCPT reaffirmed timelines for RPC1063's PII/III RADIANCE study. RCPT continues to enroll the TOUCHSTONE PII trial in Ulcerative Colitis (UC). [Full Note]

Receptos – Another Potential Winner in the Revolution – June 03 2013 Bottom Line: We Are Initiating Coverage of Receptos (RCPT) with Outperform and $21 Target Price (~30% Upside Potential). RCPT is focused on the research and development of drugs for the treatment of immunological and metabolic disorders. RCPT’s key asset is RPC1063, which is a “2nd-generation” S1P1 modulator, currently enrolling into a PII/III trial for relapsing multiple sclerosis (RMS) and a PII for ulcerative colitis. We believe that RPC1063 could be a significant winner in the MS revolution. [Full Note]

Key Points to Our 3 Bucket Thesis: (1) We view MS therapeutics in 3 broad buckets: Two established buckets (i) ABCR and (ii) High-Efficacy/Second-Line agents and an emerging new class of products that we call (iii) Oral agents (2) The overall MS market is still dominated (~80% market share by value) by ABCRs (despite their relative modest efficacy and less than ideal side effect profile) as they are the only alternatives to High-Efficacy/Second-Line agents (~20% market share by value) and their associated serious infections concerns (3) Tecfidera is the leading Oral, showing efficacy above ABCRs/near High-Efficacy/Second-Line AND possessing a better safety profile than High-Efficacy/Second-Line (and ABCRs). In our view this will allow significant market share in new patients, but also propagate significant switching from ABCRs (4) RPC1063 is an S1P1 modulator, within the same class as Gilenya. In our view, the totality of RCP1063’s clinical profile, notably improved half-life/fast recovery of lymphocytes and improved cardiotoxicity/hepatoxicity over Gilenya could effectively position RCP1063 in a different bucket relative to Gilenya

General . Orally-administered dimethyl fumarate, a prodrug of monomethyl fumarate Overview . Immunomodulator with neuroprotective properties . Obtained through acquisition of Fumapharm AG in 2006 . Tecfidera’s launch in the U.S. is off to a good start, capturing ~10% TRx share . CS assumes protection in the U.S. until 2023 and in the EU until 2019 . Phase III program (DEFINE and CONFIRM) evaluated BG-12 in RRMS Drug . Tecfidera appears to be superior to ABCRs from efficacy and safety standpoints Profile . Tecfidera had impressive efficacy and excellent safety/tolerability in DEFINE – Reduced relapse rates (vs pbo) by 53% for BID (p<0.0001) and 48% for TID (p<0.0001) – Reduced EDSS progression (vs pbo) by 38% for BID (p=0.0050) and 34% for TID (p=0.128) . CONFIRM generally “confirmed” Tecfidera’s profile established in DEFINE – Reduced relapse rates (vs pbo) 44% for BID and 51% for TID – Reduced EDSS progression (vs pbo) by 21% for BID (p=NS) and 24% for TID (p=NS) – BG-12 showed numerical superiority in reducing relapse rates and EDSS disease progression . Most common AEs in DEFINE and CONFIRM were transient flushing and GI disorders . Reduction in EDSS progression supported by integrated analysis of DEFINE and CONFIRM (32%, BID, p=0.0034 and 30%, TID, p=0.0059) Next . Q3’13 sales Catalysts .

General . Orally administered active metabolite of leflunomide Overview . Immunomodulator that reduces B- and T-cell counts by stopping cell division . Reported Q2’12 sales of €33M (launched in early Oct 2012) . Phase III program evaluated Aubagio in RRMS (TEMSO, TOWER, TENERE) and first clinical episodes suggestive of MS (TOPIC) . Being positioned for patients with early MS or moderate RRMS . CS views as potential wildcard competitor to BG-12 Drug . Efficacy appears to be comparable to ABCRs, but inferior to Immunosuppressives Profile . Safety appears to be slightly better than both ABCRs and Immunosuppressives . In TEMSO, Aubagio demonstrated modest efficacy and good safety/tolerability – Reduced relapse rates at 2 years (vs pbo) by 31% for 7 mg (p<0.001) and 32% for 14 mg (p<0.001) – Reduced EDSS (vs pbo) by 24% for 7 mg (p=0.08) and 30% for 14 mg (p=0.03) – Most common AEs due to Aubagio were diarrhea, hair thinning, elevated ALTs, and high blood pressure . TOWER confirmed the efficacy of 14mg dose . In TENERE, Aubagio showed comparable efficacy to Rebif (and rest of ABCRs) – Risk of treatment failure was comparable in all arms (49% for 7 mg, 38% for 14 mg, 42% for Rebif) – Both doses had higher annual relapse rates (0.410 for 7 mg, 0.259 for 14 mg) than Rebif (0.216) – Aubagio appears to have safety/tolerability profile comparable to that observed in TEMSO Next .

General . Yearly IV-administered humanized anti-CD52 mAb targeting B- and T-cells Overview . Immunosuppressive mechanism of action . Currently approved for treatment of B-cell chronic lymphocytic leukemia (B-CLL) . Obtained through acquisition of Genzyme . Being positioned for treatment of severe RMS . Approved by EMA on Sep 17, 2013 . Likely competitor of other Immunosuppressives (e.g. Gilenya, Tysabri) Drug . Efficacy is generally superior to ABCRs, and comparable to Immunosuppressives Profile . Both Phase III trials showed high efficacy in reducing relapse rates relative to Rebif – Reduced relapse rates (vs Rebif) by 55% in CARE-MS I (p<0.0001) and 49% in CARE-MS II (p<0.0001) . However, only CARE-MS II showed a statistically significant reduction in disease progression – In CARE-MS I, there was no statistical significant reduction in EDSS progression (vs Rebif) – In CARE-MS II, there was a 42% reduction in EDSS progression (vs Rebif) . Safety remains a concern due to increased risk of immune-related conditions including autoimmune thyroid disorders, immune thrombocytopenia, and infections . AEs leading to withdrawal and discontinuation were lower for Lemtrada relative to Rebif Next . sBLA PDUFA in Q4’13 Catalysts

General . Orally administered linomide successor Overview . Immunomodulator with potential neuroprotective properties . Expecting CHMP opinion in Q3’13 . Being developed by Teva (Obtained via partnership agreement with Active Biotech) . Originally evaluated in 2 Phase III trials, ALLEGRO and BRAVO . Teva recently initiated a third Phase III trial (CONCERTO) in RRMS evaluating two doses (0.6mg and 1.2mg) Drug . BRAVO failed to hit the primary endpoint Profile – Failed to show statistically significant reduction in relapse rates (vs pbo) – Failed to show numerical superiority in reducing relapse rates relative to active comparator Avonex – Demonstrated reduction in EDSS progression of 33.5% (p=0.044) .However, ALLEGRO did hit the primary endpoint – Showed ARR of 26% (p=0.002) and reduction in EDSS progression of 36% (p=0.0122) . Both trials though showed some very good MRI outcomes, suggesting that Laquinimode could be neuroprotective

General . Twice-a-year IV-administered, humanized anti-CD20 mAb targeting CD20+ B-cells Overview . Considered next-generation Rituxan . Roche/Genentech are lead developers, while Biogen Idec retains an economic interest . Phase III program is examining Ocrelizumab in RRMS (OPERA I/II) and PPMS (ORATORIO) . Initiated ORATORIO in Q1’11 and OPERA I/II in Q3’11 Drug . Ocrelizumab demonstrated high efficacy and good safety in a Phase II trial Profile – Reduced relapse rates at 24 weeks (vs pbo) by 80% for 600 mg arm (p=0.0005) and 73% for 2000 mg arm (p=0.0014) – Both doses showed numerical superiority in reducing relapse rates (vs pbo) over Avonex (43% vs pbo) – Incidence of SAEs were comparable across arms: 2% (600 mg), 5% (2000 mg), 4% (Avonex), 4% (pbo) – There was one death due to brain swelling in 2000 mg arm . However, safety remains a concern, as separate trials in rheumatoid arthritis and lupus erthymatosus (for 1000 mg dose) were terminated in 2010 due to side effects – DSMB review of the STAGE trial showed that numerous patients developed serious infections, of which some were fatal – Roche believes the lower dose, younger patient population, and absence of concomitant immunosuppressant use could result in a better safety/tolerability profile in patients with MS Next .

Sources: Biogen Idec, Credit Suisse research and analysis Slide 90 September 2013 What have we learned from DEFINE and CONFIRM?

. BG-12 has superior efficacy and safety relative to ABCRs – In DEFINE, ARR and reduction in EDSS progression were more substantial relative to historical data for ABCRs

. ARR reduction: 53% BID, 48% TID / EDSS reduction: 38% BID, 34% TID – In CONFIRM, BG-12 arms were superior to the Copaxone comparator arm in reducing ARR and EDSS progression

. ARR reduction: 44% BID, 51% TID, 29% Copaxone / EDSS reduction: 21% BID, 24% TID, 7% Copaxone – Most common adverse events observed in DEFINE and CONFIRM were flushing and GI disorders, both of which were transient in nature . Most common AEs (e.g. flushing and GI disorders) due to BG-12 are transient and generally easily managed, as observed in DEFINE and CONFIRM – Incidence of flushing drops off significantly after the first month (~30%  ~5%) – Incidence of GI disorders follows a similar pattern seen in flushing (~25%  ~5%) – Flushing accounted for 2% and 1% of discontinuations in BID and TID arms respectively – Aspirin can be used to reduce incidence and severity of flushing, as BIIB showed in a small trial in healthy volunteers

Sources: Biogen Idec, Credit Suisse research and analysis Slide 91 September 2013 What have we learned from DEFINE and CONFIRM? (cont.)

. MRI data appears to provide additional support for BG-12’s possible neuroprotective mechanism of action based on DEFINE and CONFIRM data sets

Data at Year 2 DEFINE CONFIRM BG-12 BID BG-12 TID BG-12 BID BG-12 TID Number of Gd+ Lesions 90% 73% N/A N/A Number of T1 Lesions 72% 63% 65% 41% Number of New/Enlarging T2 Lesions 85% 74% 71% 73%

. BG-12 appears to be more modulatory than suppressive on the immune system as shown in DEFINE and CONFIRM – Incidence of infections did not increase due to BG-12 in either trial – DEFINE: 65% pbo, 64% BID, 68% TID; CONFIRM: 50% pbo, 56% BID, 56% TID – Both white blood cell and lymphocyte counts decreased, but remained within normal limits . Integrated analysis of DEFINE and CONFIRM supports claims that BG-12 reduces disability – Reduction in EDSS progression was 32% for BID (p=0.0034) and 30% (TID, p=0.0059) in the integrated analysis – Recall, DEFINE (but not CONFIRM) showed a statistically significant reduction in EDSS progression

. Orally administered active metabolite of leflunomide . Immunomodulator that reduces B- and T-cell counts by stopping cell division . Approved by FDA on Sep 12, 2012 and EMA on Aug 30, 2013 . Received RDP status in the EU as a new active substance . Phase III program evaluated Aubagio in RMS (TEMSO, TOWER, TENERE) and first clinical episodes suggestive of MS (TOPIC) as well as Aubagio + IFN Beta I in RMS (TERACLES) . Being positioned for patients with early MS or moderate RRMS . In TEMSO, Aubagio has demonstrated modest efficacy, but good safety/tolerability: – Reduced ARR (vs pbo) by 31% for 7 mg and 32% for 14 mg – Reduced EDSS progression (vs pbo) by 24% for 7 mg and 30% for 14 mg – Most common adverse events were diarrhea, hair thinning, elevated ALTs, and high blood pressure . TOWER confirmed efficacy of 14mg dose . In TENERE, Aubagio showed that it is comparable to Rebif from statistical point of view – Risk of treatment failure was comparable in all arms (49% for 7 mg, 38% for 14 mg, 42% for Rebif) – Both doses had higher ARR (0.410 for 7 mg, 0.259 for 14 mg) than Rebif (0.216) – Side effects were similar to those observed in TEMSO

Sources: Sanofi, Credit Suisse research and analysis Slide 129 September 2013 What we learned from TEMSO, TOWER, and TENERE?

. TEMSO showed that the 14 mg Aubagio is effective in both reducing relapse rates and slowing disease progression (vs placebo) – 14 mg dose demonstrated statistical significance in reducing relapse rates (31.5%, p=0.0005) and slowing EDSS progression (29.8%, p=0.0279) – 7 mg dose showed statistical significant in reducing relapse rates (31.2%, p=0.0002), but failed to demonstrate statistical significance in slowing EDSS progression (23.7%, p=0.08) . TENERE suggests that Aubagio is comparable in efficacy to Rebif from a statistical view – Both doses did not show statistical significance in risk of treatment failure and reduction in annual relapse rates relative to Rebif – Percentage of patients reaching primary endpoint of risk of treatment failure was 48.6% for 7 mg, 37.8% for 14 mg, and 42.3% for Rebif – ARR was 0.410 for 7 mg and 0.259 for 14 mg as compared to 0.216 for Rebif . TOWER confirmed efficacy of 14mg dose in reducing relapse rates (36.3%) and 12-week EDSS progression (31.5%). . The slightly higher number of relapses in Aubagio arms (vs Rebif) in TENERE could be a slight negative for Aubagio from a commercial view – Both doses had higher relapse rates (0.410 for 7 mg, 0.259 for 14 mg) relative to Rebif (0.216)

Both trials have shown that Aubagio has a favorable safety/tolerability profile – Most common side effects in TEMSO were diarrhea, hair thinning, elevated ALTs, and high blood pressure – Safety profile in TENERE was similar to that observed in TEMSO . TENERE does show that Aubagio has a better safety/tolerability profile than Rebif – Incidence of TEAEs were lower in Aubagio (8.2% for 7 mg, 10.9% for 14 mg) than Rebif (21.8%) . TEMSO suggests Aubagio could be more immunomodulatory than immunosuppressive – Mean reductions in neutrophil and lymphocyte counts were low in magnitude, but3 patients did develop moderate neutropenia

. IV-administered humanized anti-CD52 mAb targeting B- and T-cells . Immunosuppressive mechanism of action . Currently approved for treatment of B-cell chronic lymphocytic leukemia (B-CLL) . Expecting sBLA PDUFA in Q4’13; Received EMA approval on Sep 17, 2013 . Being positioned for treatment of severe RMS . Once-yearly dosing schedule is convenient, but IV administration is not ideal . Efficacy is generally superior to ABCRs, and comparable to High-Efficacy/2nd-Line, but safety though seems to be worse than ABCRs . Both Phase III trials showed high efficacy in reducing relapse rates relative to Rebif – Reduced ARR (vs Rebif) by 55% in CARE-MS I (p<0.0001) and 49% in CARE-MS II (p<0.0001) . However, only CARE-MS II showed a statistically significant reduction in disease progression – In CARE-MS I, there was no statistical significant reduction in EDSS progression (vs Rebif) – In CARE-MS II, there was a 42% reduction in EDSS progression (vs Rebif) . Safety remains a concern due to increased risk of immune-related conditions including autoimmune thyroid disorders, immune thrombocytopenia, and infections

Sources: Sanofi, Credit Suisse research and analysis Slide 139 September 2013 What have we learned from CARE-MS I and CARE-MS II?

. Lemtrada is generally superior to Rebif (and other ABCRs) – Reductions in relapse rates at 2 years (vs Rebif) were 55% in CARE-MS I (p<0.0001) and 49% for in CARE-MS II (p<0.0001) – Reductions in EDSS progression (vs Rebif) were 42% in CARE-MS II (p=0.0084) and not meaningful in CARE-MS I (p=NS) . Lemtrada appears to be more effective in treating moderate-to-severe RRMS relative to Rebif – CARE-MS I failed to showed a statistically significant reduction in EDSS progression in naïve RRMS – CARE-MS II showed Lemtrada could be beneficial in experienced (relapsed on prior treatment) RRMS . Safety is a major concern, which could further make Lemtrada a treatment option primarily for moderate-to-severe RRMS – Most common adverse events caused by Lemtrada include autoimmune thyroid disorders, immune thrombocytopenia, and infections in CARE-MS I and CARE-MS II – The risk-benefit ratio is particularly skewed towards the downside in naïve RRMS, given safety/tolerability issues and lack of meaningful reduction in EDSS progression – However, the AEs leading to withdrawal or discontinuation were lower for Lemtrada than Rebif

. Lack of statistical significance in reducing EDSS in CARE-MS I could make claims on slowing disease progression for Lemtrada less clear-cut – Sanofi believes this miss occurred because patients in this trial had early stage MS, leading to stable disease throughout the trial

* Co-primary endpoints in CARE-MS I and CARE-MS II . Lemtrada hits only 1 of 2 co-primary endpoints in CARE-MS I, but achieves both co-primary endpoints in CARE-MS II – Lemtrada fails to show a reduction in EDSS disease progression in CARE-MS I . The safety/tolerability profiles for Lemtrada observed in CARE-MS I and CARE-MS II were generally comparable – The major adverse events include autoimmune-thyroid-related disorders, immune thrombocytopenia, and infections

. IV-administered, humanized anti-CD20 mAb targeting CD20+ B-cells . Roche/Genentech are lead developers, while Biogen Idec retains an economic interest . Phase III program is evaluating in RRMS (OPERA I and II) and PPMS (ORATORIO) . Initiated ORATORIO in Q1’11 and OPERA I/II in Q3’11 . Readouts from OPERA I/II will likely occur in 2015/2016 . Ocrelizumab demonstrated high efficacy and good safety in a Phase II trial – Reduced relapse rates at 24 weeks (vs pbo) by 80% for 600 mg arm (p=0.0005) and 73% for 2000 mg arm (p=0.0014) – Both doses showed superiority in reducing relapse rates (vs pbo) over Avonex (43% vs pbo) – Incidence of SAEs were similar across arms: 2% (600 mg), 5% (2000 mg), 4% (Avonex), 4% (pbo) – There was one death due to brain swelling in 2000 mg arm . However, safety remains a concern, as separate trials in rheumatoid arthritis and lupus erthymatosus (for 1000 mg dose) were terminated in 2010 due to side effects – DSMB review of the STAGE trial showed that numerous patients developed serious infections, of which some were fatal – Roche believes the lower dose, younger patient population, and absence of concomitant immunosuppressant use could result in a better safety/tolerability profile in patients with MS

Sources: Biogen Idec, Elan, Credit Suisse research and analysis What is PML?

. Progressive Multifocal Leukencephalopathy . Demyelinating disease caused by reactivation of JC virus . 50-92% of Americans have been infected with JC virus according to various clinical studies . Vast majority of infected patients are healthy since immune response keeps virus at bay and prevents reactivation (PML) . Disease usually seen in immunosuppressed individuals (i.e HIV, transplant recipients)

. Detects exposure to JC virus – Measures presence of anti-JCV antibodies in serum – Detecting viral DNA preferable method but not dependable because it is hard to isolate from serum – Viral DNA is easier to find in urine, but only 25% of PML patients shed virus this way . Three important read-throughs – Can the JCV test accurately detect JCV antibodies? (STRATIFY-1 full data) – What percentage of Tysabri patients are JCV antibody negative? (STRATIFY-1) – What’s the risk of PML in patients who are positive and negative for JCV antibody? (STRATIFY-2)

. JCV-like particles called MAD-1 Protein are placed into a plate . Human serum that may or may-not contain JCV antibodies are added . An anti-human IgG antibody linked to a colored substrate is then added to the mixture . A is tested for absorbance at 450nm – data read as normalized optical density units (nOD) – nOD>0.25 – seropositive – nOD<0.10 – seronegative – 0.1040% drop in nOD – seropositive

. Assay tested earlier in STRATA trial . 831pts . All patients gave serum AND urine samples . 2.5% of patients shedding virus in urine (N=204) had negative test . 54% seropositive rate – Prevalence plateaus in early-mid 20’s, then increases with age – Seropositive rate ranges from 33-91% in earlier and smaller trials . 2% seroconversion rate (becoming seropositive after originally testing seronegative)

. First Line (ABCR) – Interferon β . Introduced in 1993 . Proven to decrease relapse rate and slow down progression of disease, but not sure how it works . All injected (subcutaneous or intramuscular) . Commonly causes injection site reactions, flu-like symptoms, and elevated liver enzymes . Three on Market  Avonex – Manufactured by Biogen. Introduced in 1996. Given once/wk (IM).  Betaseron – Manufactured by Bayer. First on market in 1993. Given once every 2 days (SQ).  Rebif – Co-marketed by Pfizer and Merck Serono. Brought to U.S. in 2002. Given 3x/wk (SQ). – Copaxone . Random set of polymers that resemble myelin basic protein . May work by directing immune response away from brain and spinal cord . Marketed by Teva and Sanofi-Aventis . Approved in 1996 . Tysabri (Biogen/Elan) – Monoclonal antibody to alpha-subunit of integrin receptor – introduced in 2004 – Effective in MS, but only indicated for pts that have failed or are intolerant to ABCR therapy – IV, once a month – Use hindered by PML concerns

. Facts – Neurological disease in which the immune system attacks the protective coating of the brain and spinal cord – 350-400K pts treated for disease in U.S. – Most pts are women, diagnosed between 20-40 years of age – No known cure . Four subtypes – Relapsing-Remitting – Pts suffer clearly defined attacks followed by periods of partial or complete recovery. 85% of patients have this type upon diagnosis. Most treatable type. – Primary Progressive – No distinct relapses or remissions, but gradually worsening symptoms from beginning – Secondary Progressive – Patient originally has RRMS, but it then follows a more progressive course – Progressive RR – Clearly defined attacks and recovery on top of gradually worsening symptoms at baseline

. First evaluated in MS in 2005 study by Schrimrigk et. al

. 10 patients

. 18-55 years of age

. ≥1 relapse prior to enrollment

. EDSS Score of 2.0-6.0 . Treatment phases (70 weeks total)

. Weeks 0-18: Pts started at 30mg QD and titrated to a max of 240mg TID

. Weeks 19-22: Washout phase

. Weeks 23-70: Pts started at 30mg QD and titrated to a max of 120mg TID . Had significant reductions from baseline in the number (p<0.05) and size of Gd+ lesions (p<0.001)

. 5 patients (50%) experienced flushing . 1 discontinuation because of GI adverse event

Sources: Company reports, www.clinicaltrials.gov, Credit Suisse research and analysis Slide 183 September 2013 How do MRI Findings correlate with Clinical Status?

. T1-Weighted Lesion – Picked up on a basic MRI scan that differentiates fat from water. Fat appears brighter than water in these scans. – Used to pick up “black holes” – areas of permanent axonal damage. Likely due to the loss of fatty myelin surrounding the axons – Thought to be correlated with disability . T2-Weighted Lesion – Used to detect MRI lesions which are bright – “hyperintense” – Monitors “disease load” – May be correlated with inflammation/relapses . Gadolinium -Enhancing Lesion – Used to detect the breakdown in the blood-brain barrier – Good for spotting areas of acute inflammation – May be correlated with relapses

Sources: Company reports, www.clinicaltrials.gov, Credit Suisse research and analysis Slide 184 September 2013 What do relative relapse rates really tell us?

Placebo relapse rates have trended downward since 1996....

....As a result, neurologists focus less on relative RR reduction... But one also could argue that each % point RR decrease is harder to obtain on lower placebo annual relapse rate baselines

Sources: Company reports, www.clinicaltrials.gov, Credit Suisse research and analysis Slide 185 September 2013 EDSS progression – A better but still imperfect measure of efficacyMS drug monotherapy pivotal studies show that starting EDSS scores over time have remained stable around 2.4...... hence, there is an argument that EDSS data from ALLEGRO is more meaningful than relapse rates

Interesting thought: RR rates (and betterment over time) are not correlated with improving EDSS – subjective evidence that RR and EDSS have poor correlation?

.... However, we also note that measurement of EDSS disability progression between trials is modestly different (between a 0.5 an 1.0 point increase sustained for 3-6 months).

. Global 2 year double blind, placebo controlled . 1,260 patients with RRMS . Primary endpoint – annualized relapse rate at 1 year . Enrolment goal is YE2010 – likely results in 2013 . Received special protocol assessment from FDA in Q2

Sources: Company reports, www.clinicaltrials.gov, Credit Suisse research and analysis Slide 189 September 2013 Our take on BIIB017

. Hurdle lower than other drugs since interferons have rich history . However, only Phase I data is available, so it’s hard to access efficacy and safety risk . If approved, we expect it to cannabalize Avonex sales and its added convenience should offset pressure from orals . However, by the time PEG-Avonex is approved, we expect a paradigm shift to orals so that it won’t completely offset lost Avonex revenues
