(54) Title: METHODS AND COMPOSITIONS FOR THE TREATMENT OF DISORDERS ASSOCIATED WITH DEFECTS OF THE CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR GENE OR PROTEIN (57) Abstract: The present invention features compositions, methods, and kits for treating, or ameliorating disorders associated with a de fect in the cystic fibrosis transmembrane con ductance regulator (CFTR) gene or protein (e.g., cystic fibrosis).

Figure 1 METHODS AND COMPOSITIONS FOR THE TREATMENT OF DISORDERS ASSOCIATED WITH DEFECTS OF THE CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR GENE OR PROTEIN

Background of the Invention Cystic fibrosis (CF) is a lethal, autosomal-recessive genetic disease, affecting approximately 30,000 individuals in the United States. CF is characterized by defective chloride transport, resulting from a mutation of the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The CFTR gene encodes a linear protein in the plasma membrane of certain epithelial cells, where it regulates the flow of chloride in response to phosphorylation by a cyclic AMP-dependent kinase. Many mutations of the CFTR protein have been reported, the most common of which is a deletion of a phenylalanine residue (∆F508 CFTR). Although most people without CF have two working copies of the CFTR gene, only one is needed to prevent CF. The principal clinical manifestation of CF is the resulting respiratory disease, characterized by airway obstruction due to the presence of thick mucus that is difficult to clear from airway passages. This airway mucus contributes to recurrent bacterial infections and impaired respiration, eventually resulting in death. Treatment of CF involves the thinning of mucosal obstructions, treating bacterial infections, using anti-inflammatory compositions to treat lung inflammation, and opening airways with bronchodilators. However, even with such treatments, frequent hospitalization is often required as the disease progresses. Accordingly, improvements are needed for the treatment of CF and other disorders associated with defects of the CFTR gene or protein. Summary of the Invention The present invention features compositions, methods, and kits for treating or ameliorating disorders associated with a defect in the cystic fibrosis transmembrane conductance regulator (CFTR) gene or protein (e.g., cystic fibrosis). The invention features a composition that includes an agent selected from Table 1. Desirably, the agent is present in an amount that, when administered to a patient, is sufficient to treat or ameliorate a disorder associated with a defect in the CFTR gene or protein. In another aspect, the invention features a composition that includes a first agent selected from Table 1 or 2 and a second, different agent selected from Table 1, 2, or 3. Desirably, the agents are present in amounts that, when administered together to a patient, are sufficient to treat or ameliorate a disorder associated with a defect in the CFTR gene or protein. In another aspect, the invention features a composition that includes active ingredients and excipients, wherein the active ingredients are, for example, a first compound from Table 1 or 2 and a second compound from

Table 1, 2, or 3. In another aspect, the invention features a composition that includes a first agent selected from Table 1, a second agent selected from Table 2, and a third agent selected from Table 3. Desirably, the agents are present in amounts that, when administered together to a patient, are sufficient to treat or ameliorate a disorder associated with a defect in the CFTR gene or protein. The compositions of the invention may be formulated, for example, for oral administration, systemic administration, or for inhalation. The invention also features a method for treating or ameliorating a disorder associated with a defect in the CFTR gene or protein by administering to a patient an agent selected from Table 1 in an amount sufficient to treat or ameliorate the disorder. In another aspect, the invention features a method for treating or ameliorating a disorder associated with a defect in the CFTR gene or protein that includes administering to a patient a first agent selected from Table 1 and a second, different agent selected from Table 1, 2, or 3, wherein the agents are present in amounts that, when administered together to a patient, are sufficient to treat or ameliorate the disorder. In another aspect, the invention features a method for treating or ameliorating a disorder associated with a defect in the CFTR gene or protein that includes administering to a patient a first agent selected from Table 1, a second agent selected from Table 2, and a third agent selected from Table 3, wherein the agents are present in amounts that, when administered together to a patient, are sufficient to treat or ameliorate the disorder. The agents of the methods may be administered substantially simultaneously in amounts that together are sufficient to treat or ameliorate the disorder. Alternatively, the agents may be administered within 1, 2, 4, 6, 12, or 24 hours of each other, within 7 days of each other, within 14 days of each other, or within 28 days of each other. The agents may be administered by any appropriate route, e.g., by oral administration, systemic administration, or inhalation. The invention also features a kit that includes at least one agent selected from Table 1 and instructions for administering the agent to a patient having a disorder associated with a defect in the CFTR gene or protein (e.g., cystic fibrosis). In another aspect, the invention features a kit that includes a first agent selected from Table 1, a second, different agent selected from Table 1, 2, or 3, and instructions for administering the agents to a patient having a disorder associated with a defect in the CFTR gene or protein (e.g., cystic fibrosis). In another aspect, the invention features a kit that includes a first agent selected from Table 1, a second agent selected from Table 2, a third agent selected from Table 3, and instructions for administering the agents to a patient having a disorder associated with a defect in the CFTR gene or protein (e.g., cystic fibrosis). Combinations of the compounds described herein may be used as therapeutic agents in the compositions, methods, and kits of the present invention. Such combinations include, e.g., Corr-4a and HC toxin; Corr-4a and valproic acid; Corr-4a and suberoylanilide hydroxamic acid; and HC toxin; and suberoylanilide hydroxamic acid; and suberoylanilide hydroxamic acid; and Corr-4a; 2-APB and inhibitor III; staurosporine and suberoylanilide hydroxamic acid; BAY 60-7550 and suberoylanilide hydroxamic acid; hydrochloride and suberoylanilide hydroxamic acid; BAY 60-7550 and CF-C3; CF-C6 and ; Corr-4a and LY 294002; Corr-4a and flunixin meglumine; clofarabine and quinestrol; and CF- P5 and suberoylanilide hydroxamic acid. By "an amount sufficient" is meant the amount of a compound, alone or in combination with another compound or therapeutic regimen, required to treat or ameliorate a disorder, such as cystic fibrosis, in a clinically relevant manner. A sufficient amount of an active compound used to practice the present invention for therapeutic treatment of, e.g., cystic fibrosis, varies depending upon the manner of administration, age, and general health of the patient. Ultimately, the prescribers will decide the appropriate amount and dosage regimen. Additionally, an effective amount may be an amount of compound in the combination of the invention that is safe and efficacious in the treatment of a patient having a disorder, such as cystic fibrosis, over each agent alone as determined and approved by a regulatory authority (such as the U.S. Food and Administration). By "candidate compound" is meant a chemical, e.g., naturally-occurring or artificially-derived. Candidate compounds may include, for example, peptides, polypeptides, synthetic organic molecules, naturally-occurring organic molecules, nucleic acid molecules, peptide nucleic acid molecules, and components and derivatives thereof. Compounds useful in the invention include those described herein in any of their pharmaceutically acceptable forms, including isomers such as diastereomers and enantiomers, salts, solvates, and polymorphs thereof, as well as racemic mixtures. Compounds useful in the invention may also be isotopically labeled compounds. Useful isotopes include hydrogen, , , oxygen, phosphorous, fluorine, and chlorine, (e.g., 2H, 3H, 13 C, 14 C, 15N, 18O, 170 , 3 1P, 32P, 35S, 18F, and 36Cl). Isotopically-labeled compounds can be prepared by synthesizing a compound using a readily available isotopically- labeled reagent in place of a non-isotopically-labeled reagent. By "disorder associated with a defect in the cystic fibrosis transmembrane conductance regulator (CFTR) gene or protein" is meant any disorder resulting from a mutation of the CFTR gene or protein (e.g., a deletion of F508, a G542X mutation, a G551D mutation, a N1303K mutation, or a W1282X mutation). Exemplary disorders include cystic fibrosis, the congenital absence of the vas deferens, and some forms of pancreatitis. By a "high dosage" is meant at least 5% more (e.g., at least 10%, 20%, 30%, 40%, 50%, 100%, 150%, 200%, or 300%) than the highest standard recommended dosage of a particular compound formulated for a given route of administration for treatment of any disease or condition. For example, a high dosage of an agent that treats or prevents cystic fibrosis and that is formulated for intravenous administration may differ from a high dosage of the same agent formulated for oral administration. By a "low dosage" is meant at least 5% less (e.g., at least 10%, 20%, 50%, 80%, 90%, or 95%) than the lowest standard recommended dosage of a particular compound formulated for a given route of administration for the treatment of any disease or condition. By "patient" is meant any animal, e.g., a mammal (e.g., a human). Other animals that can be treated using the compositions, methods, and kits of the invention include, e.g., horses, dogs, cats, pigs, goats, rabbits, hamsters, monkeys, guinea pigs, rats, mice, lizards, snakes, sheep, cattle, fish, and birds. A patient who is being treated for a disorder associated with a CFTR defect (e.g., cystic fibrosis) is one who has been diagnosed by a medical practitioner as having such a condition. Diagnosis may be performed by any suitable means, such as those described herein. One in the art will understand that patients of the invention may have been subjected to standard tests or may have been identified, without examination, as one at high risk due to the presence of one or more risk factors, such as age, genetics, or family history. By "pharmaceutically acceptable salt" is meant salts which are, within the scope of sound medical judgment, suitable for use in contact with the tissues of humans and lower animals without undue , irritation, allergic response and the like, and are commensurate with a reasonable benefit/risk ratio. Pharmaceutically acceptable salts are well known in the art. The salts can be prepared in situ during the final isolation and purification of the compounds of the invention, or separately by reacting the free base function with a suitable organic acid. Representative acid addition salts include, e.g., acetate, ascorbate, aspartate, benzoate, citrate, digluconate, fumarate, glucoheptonate, glycerophosphate, hemisulfate, heptonate, hexanoate, hydrobromide, hydrochloride, hydroiodide, lactate, malate, maleate, malonate, mesylate, oxalate, phosphate, succinate, sulfate, tartrate, thiocyanate, valerate salts, and the like. Representative alkali or alkaline earth metal salts include , , potassium, calcium, , and the like, as well as nontoxic ammonium, quaternary ammonium, and amine cations, including, but not limited to ammonium, tetramethylammonium, , methylamine, dimethylamine, trimethylamine, triethylamine, and ethylamine. By "sustained release" or "controlled release" is meant that the therapeutically active component is released from the formulation at a controlled rate such that therapeutically beneficial blood levels (but below toxic levels) of the component are maintained over an extended period of time ranging from, e.g., about 12 to about 24 hours, thus, providing, for example, a 12-hour or a 24-hour dosage form. By "systemic administration" is meant any non-dermal route of administration, and specifically excludes topical and transdermal routes of administration. By "therapeutic agent" is meant any agent that produces a healing, curative, stabilizing, or ameliorative effect. By "treating or ameliorating" is meant ameliorating a condition or symptoms of the condition (e.g., cystic fibrosis) before or after its onset. As compared with an equivalent untreated control, such amelioration or degree of treatment is at least 5%, 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, 95%, or 100% as measured by any standard technique. Exemplary therapeutic agents used for the treatment of any patient that has been diagnosed with a disorder associated with defects of a CFTR gene or protein are listed in Tables 1, 2, and 3.

(FL FSK or with forskolin and a candidate compound (FL FSK+GEN) before and after contact with an iodide solution. Detailed Description of the Invention We have discovered compounds that, alone or in combination, increase the recruitment of ∆F508 cystic fibrosis transmembrane conductance regulator (CFTR) proteins to the plasma membrane of a cell or enhance the activity of ∆F508 CFTR proteins already present in the plasma membrane. Thus, these compounds may be useful for treating a patient that has been diagnosed with a disorder associated with a defect in the CFTR gene or protein. Optionally, analogs of these compounds may be employed. In the case of cystic fibrosis, for example, such administration may decrease mucus production, decrease sputum viscosity, decrease blood pressure of the lung, reduce inflammation of the sinuses, lung, and pancreas, decrease thickened secretions that block bile ducts, control CF-related diabetes, or maximize organ function.

Diagnosis of Disorders Associated with Defects of the CFTR Gene or Protein The compositions, methods, and kits of the present invention are useful for treating any patient that has been diagnosed with a disorder associated with defects of the CFTR gene or protein (e.g., cystic fibrosis). One in the art will understand that patients of the invention may have been subjected to standard tests or may have been identified, without examination, as one at high risk due to the presence of one or more risk factors. Diagnosis of these disorders may be performed using any standard method known in the art, such as those described herein. Methods for diagnosing CFTR-defect disorders are described, for example, in U.S. Patent Nos. 3,902,847, 4,273,869, 4,469,788, and 7,160,729, hereby incorporated by reference. CFTR-defect disorders, e.g., CF, may be diagnosed and monitored using, for example, sweat (or chloride) tests to measure the amount of chloride in the sweat, which involves stimulating sweat from the patient with a mild electric current. The sweat is collected onto a gauze pad and analyzed. Higher than normal concentrations of chloride may be suggestive of a CFTR-defect disorder. Blood tests may also be performed to test for mutations in the CFTR gene. Chest x-rays, pulmonary function tests (e.g., diagnostic tests that help to measure the lungs' ability to exchange oxygen and carbon dioxide), sputum cultures, stool evaluations (e.g., to measure stool fat absorption), and pancreatic function tests may also be used to diagnosis CFTR-defect disorders. The use of any of the above tests or any other tests known in the art may be used to monitor the efficacy of the present treatment.

Therapeutic Agents Exemplary therapeutic agents used for the treatment of any patient that has been diagnosed with a disorder associated with defects of a CFTR gene or protein are listed in Tables 1, 2, and 3. Preferred agents include, e.g., , , , dihydropyridines, HDAC inhibitors, sulfonylureas, PPAR , / modulators, PDE inhibitors and receptor modulators, kinase inhibitors, NSAIDs and leukotriene antagonists, proton pump inhibitors, channel modulators, and receptor modulators.

If more than one agent is employed, therapeutic agents may be delivered separately or may be admixed into a single formulation. When agents are present in different pharmaceutical compositions, different routes of administration may be employed. Routes of administration for the various embodiments include, but are not limited to, topical, transdermal, and systemic administration (e.g., intravenous, intramuscular, subcutaneous, inhalation, rectal, buccal, vaginal, intraperitoneal, intraarticular, ophthalmic or oral administration). As used herein, "systemic administration" refers to all non- dermal routes of administration, and specifically excludes topical and transdermal routes of administration. Desirably, the agent of the invention and additional therapeutic agents are administered within at least 1, 2, 4, 6, 10, 12, 18, 24 hours, 3 days, 7 days, 14 days, or 28 days apart. The dosage and frequency of administration of each component of the combination can be controlled independently. For example, one compound may be administered three times per day, while the second compound may be administered once per day. Combination therapy may be given in on-and-off cycles that include rest periods so that the patient's body has a chance to recover from any as yet unforeseen side effects. The compounds may also be formulated together such that one administration delivers both compounds. Optionally, any of the agents of the combination may be administered in a low dosage or in a high dosage, each of which is defined herein. The therapeutic agents of the invention may be admixed with additional active or inert ingredients, e.g., in conventional pharmaceutically acceptable carriers. A pharmaceutical carrier can be any compatible, non-toxic substance suitable for the administration of the compositions of the present invention to a mammal. Pharmaceutically acceptable carriers include, for example, water, saline, buffers and other compounds described, for example, in the , Merck & Co., Rahway, New Jersey. Slow release formulation or a slow release apparatus may be also be used for continuous administration. In addition to the administration of therapeutic agents, the additional therapeutic regimen may involve, e.g., gene therapy, lung transplantation, or a modification to the lifestyle of the patient being treated. Such lifestyle changes may be helpful to control the disorder and include weight loss, physical exercise, diet control, reduction in intake, or reduction in smoking.

Conjugates and Linkers If desired, the drugs used in any of the combinations described herein may be covalently attached to one another to form a conjugate of formula XXX.

(A)-(L)-(B) (XXX)

In formula XXX, (A) is a compound listed in, e.g., Table 1, Table 2, or Table 3 covalently tethered via a linker (L) to (B), a compound of, e.g., Table

1, Table 2, or Table 3. Conjugates of the invention can be administered to a subject by any route and for the treatment of any disease described herein. The conjugates of the invention can be prodrugs, releasing drug (A) and drug (B) upon, for example, cleavage of the conjugate by intracellular and extracellular (e.g., amidases, esterases, and phosphatases). The conjugates of the invention can also be designed to largely remain intact in vivo, resisting cleavage by intracellular and extracellular enzymes. The degradation of the conjugate in vivo can be controlled by the design of linker (L) and the covalent bonds formed with drug (A) and drug (B) during the synthesis of the conjugate. Conjugates can be prepared using techniques familiar to those skilled in the art. For example, the conjugates can be prepared using the methods disclosed in G. Hermanson, Bioconjugate Techniques, Academic Press, Inc., 1996. The synthesis of conjugates may involve the selective protection and deprotection of , amines, ketones, sulfhydryls or carboxyl functional groups of drug (A), the linker, and/or drug (B). For example, commonly used protecting groups for amines include , such as tert-butyl, benzyl, 2,2,2-trichloroethyl, 2-trimethylsilylethyl, 9-fluorenylmethyl, allyl, and m- nitrophenyl. Other commonly used protecting groups for amines include amides, such as formamides, acetamides, trifluoroacetamides, sulfonamides, trifluoromethanesulfonyl amides, trimethylsilylethanesulfonamides, and tert- butylsulfonyl amides. Examples of commonly used protecting groups for carboxyls include esters, such as methyl, ethyl, 9-fluorenylmethyl, 2- (trimethylsilyl)ethoxy methyl, benzyl, diphenylmethyl, O-nitrobenzyl, ortho- esters, and halo-esters. Examples of commonly used protecting groups for alcohols include ethers, such as methyl, methoxymethyl, methoxyethoxymethyl, methylthiomethyl, benzyloxymethyl, tetrahydropyranyl, ethoxyethyl, benzyl, 2-napthylmethyl, O-nitrobenzyl, P- nitrobenzyl, P-methoxybenzyl, 9-phenylxanthyl, trityl (including methoxy- trityls), and silyl ethers. Examples of commonly used protecting groups for sulfhydryls include many of the same protecting groups used for hydroxyls. In addition, sulfhydryls can be protected in a reduced form (e.g., as disulfides) or an oxidized form (e.g., as sulfonic acids, sulfonic esters, or sulfonic amides). Protecting groups can be chosen such that selective conditions (e.g., acidic conditions, basic conditions, catalysis by a nucleophile, catalysis by a Lewis acid, or hydrogenation) are required to remove each, exclusive of other protecting groups in a molecule. The conditions required for the addition of protecting groups to amine, alcohol, sulfhydryl, and carboxyl functionalities and the conditions required for their removal are provided in detail in T.W. Green and P.G.M. Wuts, Protective Groups in Organic Synthesis (2nd Ed.), John Wiley & Sons, 1991 and P.J. Kocienski, Protecting Groups, Georg Thieme Verlag, 1994. Additional synthetic details are provided below. The linker component of the invention is, at its simplest, a bond between drug (A) and drug (B), but typically provides a linear, cyclic, or branched molecular skeleton having pendant groups covalently linking drug (A) to drug (B). Thus, linking of drug (A) to drug (B) is achieved by covalent means, involving bond formation with one or more functional groups located on drug (A) and drug (B). Examples of chemically reactive functional groups which may be employed for this purpose include, without limitation, amino, hydroxyl, sulfhydryl, carboxyl, carbonyl, carbohydrate groups, vicinal diols, thioethers, 2-aminoalcohols, 2-aminothiols, guanidinyl, imidazolyl, and phenolic groups. The covalent linking of drug (A) and drug (B) may be effected using a linker, which contains reactive moieties capable of reaction with such functional groups present in drug (A) and drug (B). For example, an amine group of drug (A) may react with a carboxyl group of the linker, or an activated derivative thereof, resulting in the formation of an amide linking the two. Examples of moieties capable of reaction with sulfhydryl groups include α -haloacetyl compounds of the type XCH 2CO- (where X=Br, Cl or I), which show particular reactivity for sulfhydryl groups, but which can also be used to modify imidazolyl, thioether, phenol, and amino groups as described by Gurd, Methods Enzymol. 11:532 (1967). N-Maleimide derivatives are also considered selective towards sulfhydryl groups, but may additionally be useful in coupling to amino groups under certain conditions. Reagents such as 2- iminothiolane (Traut et al., Biochemistry 12:3266 (1973)), which introduce a thiol group through conversion of an amino group, may be considered as sulfhydryl reagents if linking occurs through the formation of disulphide bridges. Examples of reactive moieties capable of reaction with amino groups include, for example, alkylating and acylating agents. Representative alkylating agents include: (i) α-haloacetyl compounds, which show specificity towards amino groups in the absence of reactive thiol groups and are of the type XCH 2CO- (where X=Cl, Br or I), for example, as described by Wong, Biochemistry 24:5337 (1979); (ii) N-maleimide derivatives, which may react with amino groups either through a Michael type reaction or through acylation by addition to the ring carbonyl group, for example, as described by Smyth et al., JAm Chem Soc. 82:4600 (1960) and Biochem J. 9 1:589 (1964); (iii) aryl halides such as reactive nitrohaloaromatic compounds; (iv) alkyl halides, as described, for example, by McKenzie et al., J Protein Chem. 7:581 (1988); (v) aldehydes and ketones capable of Schiff s base formation with amino groups, the adducts formed usually being stabilized through reduction to give a stable amine; (vi) epoxide derivatives such as and bisoxiranes, which may react with amino, sulfhydryl, or phenolic hydroxyl groups; (vii) chlorine-containing derivatives of s-triazines, which are very reactive towards nucleophiles such as amino, sufhydryl, and hydroxyl groups; (viii) aziridines based on s-triazine compounds detailed above, e.g., as described by Ross, J Adv Cancer Res. 2:1 (1954), which react with nucleophiles such as amino groups by ring opening; (ix) squaric acid diethyl esters as described by Tietze, Chem Ber. 124:1215 (1991); and (x) α-haloalkyl ethers, which are more reactive alkylating agents than normal alkyl halides because of the activation caused by the ether oxygen atom, as described by Benneche et al., Eur J Med Chem. 28:463 (1993). Representative amino-reactive acylating agents include: (i) isocyanates and , particularly aromatic derivatives, which form stable urea and thiourea derivatives respectively; (ii) sulfonyl chlorides, which have been described by Herzig et al., Biopolymers 2:349 (1964); (iii) acid halides; (iv) active esters such as nitrophenylesters or N-hydroxysuccinimidyl esters; (v) acid anhydrides such as mixed, symmetrical, or N- carboxyanhydrides; (vi) other useful reagents for amide bond formation, for example, as described by M. Bodansky, Principles of Peptide Synthesis, Springer-Verlag, 1984; (vii) acylazides, e.g. wherein the azide group is generated from a preformed hydrazide derivative using sodium nitrite, as described by Wetz et al., Anal Biochem. 58:347 (1974); and (viii) imidoesters, which form stable amidines on reaction with amino groups, for example, as described by Hunter and Ludwig, J Am Chem Soc. 84:3491 (1962). Aldehydes and ketones may be reacted with amines to form Schiff s bases, which may advantageously be stabilized through reductive amination. Alkoxylamino moieties readily react with ketones and aldehydes to produce stable alkoxamines, for example, as described by Webb et al., in Bioconjugate Chem. 1:96 (1990). Examples of reactive moieties capable of reaction with carboxy1groups include diazo compounds such as diazoacetate esters and diazoacetamides, which react with high specificity to generate ester groups, for example, as described by Herriot, Adv Protein Chem. 3:169 (1947). Carboxyl modifying reagents such as carbodiimides, which react through O- formation followed by amide bond formation, may also be employed. It will be appreciated that functional groups in drug (A) and/or drug (B) may, if desired, be converted to other functional groups prior to reaction, for example, to confer additional reactivity or selectivity. Examples of methods useful for this purpose include conversion of amines to carboxyls using reagents such as dicarboxylic anhydrides; conversion of amines to thiols using reagents such as N-acetylhomocysteine thiolactone, S-acetylmercaptosuccinic anhydride, 2-iminothiolane, or thiol-containing succinimidyl derivatives; conversion of thiols to carboxyls using reagents such as α -haloacetates; conversion of thiols to amines using reagents such as ethylenimine or 2- bromoethylamine; conversion of carboxyls to amines using reagents such as carbodiimides followed by diamines; and conversion of alcohols to thiols using reagents such as tosyl chloride followed by transesterification with thioacetate and to the thiol with sodium acetate. So-called zero-length linkers, involving direct covalent joining of a reactive chemical group of drug (A) with a reactive chemical group of drug (B) without introducing additional linking material may, if desired, be used in accordance with the invention. Most commonly, however, the linker will include two or more reactive moieties, as described above, connected by a spacer element. The presence of such a spacer permits bifunctional linkers to react with specific functional groups within drug (A) and drug (B), resulting in a covalent linkage between the two. The reactive moieties in a linker may be the same (homobifunctional linker) or different (heterobifunctional linker, or, where several dissimilar reactive moieties are present, heteromultifunctional linker), providing a diversity of potential reagents that may bring about covalent attachment between drug (A) and drug (B). Spacer elements in the linker typically consist of linear or branched

_i chains and may include a C 10 alkyl, C2 0 alkenyl, C2-io alkynyl, C2- heterocyclyl, C - I2 aryl, C7_14 alkaryl, C3_io alkheterocyclyl, or C1_1o heteroalkyl. In some instances, the linker is described by formula (XXXI):

1 l 1 2 3 2 4 2 G -(Z )0-(Y )u-(Z )s-(R3o)-(Z )t-(Y )v-(Z )p-G (XXXI)

In formula (XXXI), G is a bond between drug (A) and the linker; G is a bond between the linker and drug (B); Z1, Z2, Z3, and Z4 each, independently, is selected from O, S, and NR31; R3 is hydrogen, C 4 alkyl, C2_4 alkenyl, C2 alkynyl, C2_6 heterocyclyl, C -n aryl, C7_i4 alkaryl, C3_io alkheterocyclyl, or Ci_ 1 2 7 heteroalkyl; Y and Y are each, independently, selected from carbonyl, thiocarbonyl, sulphonyl, or phosphoryl; o, p, s, t, u, and v are each, independently, 0 or 1; and R30 is a Ci_10 alkyl, C2_io alkenyl, C2_10 alkynyl, C2_6 heterocyclyl, C 12 aryl, C7_14 alkaryl, C3_10 ] alkheterocyclyl, or C1 I0 heteroalkyl, or a chemical bond linking G -(Z )0- 2 3 2 4 2 (YX-(Z X- to -(Z )t-(Y ) -(Z )P- G . Examples of homobifunctional linkers useful in the preparation of conjugates of the invention include, without limitation, diamines and diols selected from ethylenediamine, propylenediamine and hexamethylenediamine, glycol, diethylene glycol, propylene glycol, 1,4-butanediol, 1,6- hexanediol, cyclohexanediol, and polycaprolactone diol.

Formulation Any of the agents employed according to the present invention may be contained in any appropriate amount in any suitable carrier substance, and is generally present in an amount of 1-95% by weight of the total weight of the composition. The composition may be provided in a dosage form that is, e.g., suitable for the oral, parenteral (e.g., intravenous or intramuscular), rectal, cutaneous, nasal, vaginal, inhalant, skin (patch), or ocular administration route. Thus, the composition may be in the form of, e.g., tablets, capsules, pills, powders, granulates, suspensions, emulsions, solutions, gels (e.g., hydrogels), pastes, ointments, creams, plasters, drenches, osmotic delivery devices, suppositories, enemas, injectables, implants, sprays, or aerosols. The pharmaceutical compositions may be formulated according to conventional pharmaceutical practice (see, e.g., Remington: The Science and Practice of Pharmacy, 20th edition, 2000, ed. A.R. Gennaro, Lippincott Williams & Wilkins, Philadelphia, and Encyclopedia of Pharmaceutical Technology, eds. J. Swarbrick and J. C. Boylan, 1988-1999, Marcel Dekker, New York). For intranasal administration or administration by inhalation, the compounds of the invention may be delivered in the form of, e.g., a solution or suspension from a pump spray container that is squeezed or pumped by the patient, or as an aerosol spray from a pressurized container or a nebulizer, with the use of a suitable propellant, e.g., dichlorodifluoromethane, trichlorofluoromethane, dichlorotetrafluoroethane, carbon dioxide, or other suitable gas. In the case of a pressurized aerosol, the dosage unit may be determined by providing a valve to deliver a metered amount. The pressurized container or nebulizer may contain a solution or suspension of the active compound. Capsules and cartridges (made, for example, from gelatin) for use in an inhaler or insufflator may be formulated containing a powder mix of a compound of the invention and a suitable powder base such as lactose or starch. If more than one agent is employed, each agent may be formulated in a variety of ways that are known in the art. Desirably, the agents are formulated together for the simultaneous or near simultaneous administration of the agents. Such co-formulated compositions can include the two agents formulated together in the same, e.g., pill, capsule, or liquid. It is to be understood that, when referring to the formulation of such combinations, the formulation technology employed is also useful for the formulation of the individual agents of the combination, as well as other combinations of the invention. By using different formulation strategies for different agents, the pharmacokinetic profiles for each agent can be suitably matched. The individually or separately formulated agents can be packaged together as a kit. Non-limiting examples include kits that contain, e.g., two pills, a pill and a powder, a suppository and a liquid in a vial, or two topical creams. The kit can include optional components that aid in the administration of the unit dose to patients, such as vials for reconstituting powder forms, syringes for injection, customized intravenous delivery systems, or inhalers. Additionally, the unit dose kit can contain instructions for preparation and administration of the compositions. The kit may be, e.g., manufactured as a single use unit dose for one patient, multiple uses for a particular patient (e.g., at a constant dose or in which the individual compounds may vary in potency as therapy progresses), or the kit may contain multiple doses suitable for administration to multiple patients (e.g., bulk packaging). The kit components may be assembled in, e.g., cartons, blister packs, bottles, or tubes.

Dosages Generally, when administered to a human, the dosage of any of the agents of the invention will depend on the nature of the agent, and can readily be determined by one skilled in the art. Typically, such dosage is normally about 0.001 mg to 2000 mg per day, desirably about 1 mg to 1000 mg per day, and more desirably about 5 mg to 500 mg per day. Administration of each drug, alone or in combination, can be one to four times daily for one day to one year, and may even be for the life of the patient. Chronic, long-term administration will be required in many cases. Appropriate dosages of compounds used in the methods described herein depend on several factors, including the administration method, the severity of the disorder, and the age, weight, and health of the patient to be treated. Additionally, pharmacogenomic information (e.g., the effect of genotype on the pharmacokinetic, pharmacodynamic, or efficacy profile of a therapeutic) about a particular patient may affect the dosage used.

Additional Applications If desired, the compounds of the invention may be employed in mechanistic assays to determine whether other single agents or combinations of agents are effective in the treatment or amelioration of a disorder associated with a defect in CFTR gene or protein using assays generally known in the art, examples of which are described herein. For example, candidate compounds may be tested, alone or in combination and contacted with cells that express a mutated CFTR (e.g., CTFR-∆F508) and a fluorescent marker (e.g., yellow fluorescent protein (YFP)) to determine the functionality (e.g., openness) and/or abundance of the CFTR channels. After a suitable time, iodide is applied to the cells. By increasing the total number of channels or increasing the probability that the channels will be open, the CFTR therapeutic agents of the invention accelerate YFP quenching. Thus, an increase in the rate of fluorescence decay in this particular assay would indicate that the candidate compound would be a suitable CFTR therapeutic agent for the treatment of a disorder associated with a defect in CFTR gene or protein.

Examples Example 1. CFTR YFP Ranking Screen and Identification of Therapeutic Agents for the Treatment of a Disorder Associated with a Defect in the CFTR Gene or Protein

The goal of the CFTR yellow fluorescent protein (YFP) ranking screen was to select single agents from a chemical library that increase recruitment of ∆F508 CFTR proteins to the plasma membrane of a cell or enhance existing CFTR channel activities. This screen was performed in Fischer rat thyroid (FRT) cell lines expressing both ∆F508 CFTR and YFP in a 384-well plate format. Four different assay protocols were used to identify these agents. In one protocol, the cells were incubated with candidate compounds at 37°C for 24 hours. After washing, the cells were stimulated with forskolin and a compound known to open CFTR channels before being read on a plate reader. In the second assay, the number of ∆F508 CFTR channels in the plasma membrane was increased by incubating the cells at 27°C for 24 hours. The cells were then washed and treated with forskolin and the candidate compounds. In the third and fourth assays, the cells were incubated with candidate compounds at either 27°C or at 37°C for 24 hours, the plate-washing step was omitted, and the cells were stimulated with forskolin prior to reading on a plate reader. YFP fluorescence intensity was read with a plate reader at high speed before and after iodide was injected into each well of the plate. Iodide enters the cell via open CFTR channels in the plasma membrane and quenches YFP fluorescence. The rate of fluorescence decay is directly related to the total CFTR activity in the cell membranes. By increasing the total number of ∆F508 CFTR channels in the plasma membrane or their open probability, CFTR-∆F508 therapeutic agents accelerate YFP quenching.

Materials and Methods The materials used in these assays included FRT cells stably expressing ∆F508 CFTR and H148Q/I152L eYFP or H148Q/I152L eYFP only. The cells were cultured in T-175 flasks (Corning, Catalog No. 43 1080) or CeIlFarm high-density flasks (Fisher, Catalog No. 13-700-407) with Coon's medium (Sigma, Catalog No. F6636) containing 10% FBS (Gibco, Catalog No. 26140), 1% Penicillin-Streptomycin (Cellgro, Catalog No. 30-002-CI), 2.68 g/L sodium bicarbonate, 2 mM L- (Gibco, Catalog No. 25030-081), and 1 mg/ml G418 for the YFP cells. One T-175 flask of cells provided enough cells to seed two 384-well plates at 50,000 cells/well and 50 µl per well; one CellFarm flask seeded about ten times as much. Once the cells were confluent in the flasks, the cells were rinsed with PBS (10 ml for a T-175 flask; 50 ml for a CellFarm flask). Trypsin-EDTA was added to the cells (5 ml for a T-175 flask; 50 ml for a CellFarm flask). The cells were incubated at 37°C for 10-15 minutes. Cell culture media was added to neutralize the trypsin and cells were vigorously pipetted to break apart cell clumps. For passaging, the cells were split at a ratio of 1:3 or 1:4 (30 ml media per T- 175 flask; 500 ml media per CellFarm flask). For seeding cells on assay plates, all cell suspensions were mixed together and the cell density was counted. Additional media was added to dilute the cells to a concentration of 1 million cells per ml. Cells were plated at 50,000 per well in 50 µl. PBS-iodide solution was made with the following concentrations of salts: 0.7 mM CaCl2, 2.7 mM KCl, 1.5 mM KH2PO4, 1.1 mM MgCl 2, 154 mM

NaI, and 8.1 mM NaHPO 4, with the pH adjusted to 7.4. With all assays, 50,000 cells in 50 µl media were plated in each well of a 384-well plate (Matrix). For the first assay, the plates were incubated for 60 minutes at 37°C and 5% CO2. The drugs were diluted 1:100 in culture media and then added at a ratio of 1:10 to the wells. The plates were then incubated for 24 hours at 37°C and 5% CO2. The following day, the plates were washed twice with DPBS and stimulated with 20 µM forskolin and 3 µM CF-P3 in DPBS for 60 minutes at room temperature before making a fluorescence reading on a plate reader (Hamamatsu FDSS-6000). For the second assay, the plates were incubated for 24 hours at 27°C and

5% CO2. The following day, the plates were washed twice with DPBS and treated with drugs, diluted 1:100 in culture media and then added at a ratio of 1:10 to the wells, and 20 µM forskolin for 60 minutes at room temperature before reading on the plate reader. For the third assay, the plates were incubated for 60 minutes at 27°C and

5% CO2. The drugs were diluted 1:100 in culture media and then added at a ratio of 1:10 to the wells. The plates were then incubated for 24 hours at 27°C µ and 5% CO2. The following day, the plates were stimulated with 20 M of forskolin added to the culture media and incubated for 60 minutes at room temperature before reading on the plate reader. For the fourth assay, the plates were incubated for 60 minutes at 37°C and 5% CO2. The drugs were diluted 1:100 in culture media and then added at a ratio of 1:10 to the wells. The plates were then incubated for 24 hours at

37°C and 5% CO2. The following day, the plates were stimulated with 20 of µM forskolin for 60 minutes at room temperature before reading on the plate reader. In the plate reader, the cells were excited with UV light at 500 nm and the fluorescence emitted at 540 nm was read at 5 Hz. After a 6-second baseline read, PBS-iodide was added to the wells.

Data Analysis A representative sample of the data collected is shown in Figure 1. The amount of fluorescence remaining 10 seconds after adding iodide was recorded and the rate of fluorescence quenching was calculated using the following equation to fit the data: ( y = (Ao - A 1)e- " < + A ϊ

The user input included t0 (injection time), tN (fluorescence level (FL) sample time), and t (end of data fitting point). The return values included QR (fluorescence quenching rate, inverse of decay time constant tau) and FL

(fluorescence level given in percentage number at t = tN). The endpoints included:

FL-delta = FL background- FL (default primary endpoint, used for Z ' calculations)

FL = 100 x Fluorescence (t = tN) I Fluorescence (t = to). FLbackground = mean of FL of background wells (FLB) The fluorescence level (FL) was normalized (0 to 100) at the sampling point (tu). Each FL value was taken from the kinetic fitting results to reduce noise and spikes from raw data. The quenching rate (QR) was determined by exponential fitting of the fluorescence decay from the point of iodide injection (to) to the end of fitting

1 range (tE). QR has a dimension of s . QRbackground mean of QR of background wells (QRB)

A 0 = initial fluorescence amplitude at t = t0 A o was directly read from the raw data file generated by the plate reader used for QC. The calculated values included:

FL- fold = (FLbackground FL) / (FLbackground F L untrea ted)

FL untreatec] was the mean value of F L from an untreated well. θ QR-f ld = QR / Q R untreated

QR umreated was the mean value of Q R from an untreated well. Results Table 4 shows enhancement of existing CFTR channel activities in cells contacted with the candidate compound compared to untreated cells (denoted as Max Fold).

Table 4 Compounds that increased the recruitment of ∆F508 CFTR proteins to the plasma membrane of cells are listed in Table 5. Table 5 shows compounds that increased recruitment of ∆F508 CFTR proteins to the plasma membrane in cells when contacted with the candidate compound compared to untreated cells (denoted as Max Fold).

Table 5 Table 6 shows the reference name and chemical name for each CF reference compound. Tables 7-2 1 show combinations of compounds that enhanced CFTR channel activities in cells contacted with the candidate compounds compared to untreated cells (denoted as Max Combination Effect (MCE, based on Max Fold) and Synergy Score (SS)). A synergy score was

(/dat calculated by the formula S= logfx \ogfγ / data a-4oewe), summed over all non-single-agent concentration pairs, and where are the natural logarithm of the dilution factors used for each single agent. This effectively calculates a volume between the measured and Loewe additive response surfaces, weighted towards high inhibition and corrected for varying dilution factors. In general, the magnitude of the synergy score indicates the strength of the synergistic interaction. To select desirable combinations for follow-up characterization, the following criteria were established: (1) significant synergy over the additive model as measured by the synergy score with a cut-off value = 2.0, and (2) substantial activity where the synergy occurs and/or sufficient potency shifting occurs, with a maximum effect (MCE) greater or equal to 2.0 for combinations.
