Salts and crystalline forms of an apoptosis-inducing agent

Abstract

Salts and crystalline forms of 4-(4-{[2-(4-chlorophenyl)-4,4-dimethylyclohex-1-en-1-yl]methyl}piperazin-1-yl)-N-({3-nitro-4-[(tetrahydro-2H-pyran-4-ylmethyl)amino]phenyl}-sulfonyl)-2-(1H-pyrrolo[2,3-b]pyridin-5-yloxy)benzamide are suitable active pharmaceutical ingredients for pharmaceutical compositions useful in treatment of a disease characterized by overexpression of one or more anti-apoptotic Bcl-2 family proteins, for example cancer.

1 .- 16 . (canceled) 
     
     
         17 . A method for treating a hematopoietic malignancy in a human patient, comprising:
 orally administering to the human patient a solid dosage form prepared by dissolving a free base crystalline form of 4-(4-{[2-(4-chlorophenyl)-4,4-dimethylcyclohex-1-en-1-yl]methyl}piperazin-1-yl)-N-({3-nitro-4-[(tetrahydro-2H-pyran-4-ylmethyl)amino]phenyl}sulfonyl)-2-(1H-pyrrolo[2,3-b]pyridin-5-yloxy)benzamide (Compound 1) in a pharmaceutically acceptable solvent or mixture of solvents in an amount sufficient to deliver a therapeutically effective amount of Compound 1 to the human patient.   
     
     
         18 . The method of  claim 17 , wherein the hematopoietic malignancy is a lymphoid malignancy. 
     
     
         19 . The method of  claim 18 , wherein the lymphoid malignancy is chronic lymphocytic leukemia. 
     
     
         20 . The method of  claim 17 , wherein the therapeutically effective amount is 100 mg of Compound 1.
