Abstract

The present invention is directed to a combination therapy involving a type II anti-CD20 antibody and a selective Bcl-2 inhibitor for the treatment of a patient suffering from cancer, particularly, a CD20-expressing cancer.

First claim

What is claimed is:

1. A method for the treatment of a cancer in a human in need thereof comprising co-administering to said human an effective amount of a GA101 antibody and 2-(1H-pyrrolo[2,3-b]pyridin-5-yloxy)-4-(4((2-(4-chlorophenyl)-4,4-dimethylcyclohex-1-enyl)methyl)piperazin-1-yl)-N-(3-nitro-4-((tetrahydro-2H-pyran-4-yl)methylamino)phenylsulfonyl)benzamide or a pharmaceutically acceptable salt thereof for one or more dosing periods, followed by (i) administering to said human an effective amount of said GA101 antibody alone in the absence of 2-(1H-pyrrolo[2,3-b]pyridin-5-yloxy)-4-(4-((2-(4-chlorophenyl)-4,4-dimethylcyclohex-1-enyl)methyl)piperazin-1-yl)-N-(3-nitro-4-((tetrahydro-2H-pyran-4-yl)methylamino)phenylsulfonyl)benzamide or a pharmaceutically acceptable salt thereof for one or more dosing periods, or (ii) administering to said human an effective amount of 2-(1H-pyrrolo[2,3-b]pyridin-5-yloxy)-4-(4(2-(4-chlorophenyl)-4,4-dimethylcyclohex-1-enyl)methyl)piperazin-1-yl)-N-(3-nitro-4-((tetrahydro-2H-pyran-4-yl)methylamino)phenylsulfonyl)benzamide or a pharmaceutically acceptable salt thereof alone in the absence of said GA101 antibody for one or more dosing periods, wherein the cancer is a CD20-expressing cancer.

2. A method for the treatment of a cancer in a human in need thereof comprising co-administering an effective amount of a GA101 antibody and 2-(1H-pyrrolo[2,3-b]pyridin-5-yloxy)-4-(4(4-((2-(4-chlorophenyl)-4,4-dimethylcyclohex-1-enyl)methyl)piperazin-1-yl)-N-(3-nitro-4-((tetrahydro-2H-pyran-4-yl)methylamino)phenylsulfonyl)benzamide or a pharmaceutically acceptable salt thereof for one or more dosing periods, followed by (i) administering to said human an effective amount of said GA101 antibody alone in the absence of 2-(1H-pyrrolo[2,3 ]pyridin-5-yloxy)-4-(4-((2-(4-chlorophenyl)-4,4-dimethylcyclohex-1-enyl)methyl)piperazin-1-yl)-N-(3-nitro-4-((tetrahydro-2H-pyran-4-yl)methylamino)phenylsulfonyl)benzamide or a pharmaceutically acceptable salt thereof for 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 or 14 days, or (ii) administering to said human an effective amount of 2-(1H-pyrrolo[2,3-b]pyridin-5-yloxy)-4-(4-((2-(4-chlorophenyl)-4,4-dimethylcyclohex-1-enyl)methyl)piperazin-1-yl)-N-(3-nitro-4-((tetrahydro-2H-pyran-4-yl)methylamino)phenylsulfonyl)benzamide or a pharmaceutically acceptable salt thereof alone in the absence of said GA101 antibody for 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13 or 14 days, wherein the cancer is a CD20-expressing cancer.

3. The method of claim 1 , comprising co-administering an effective amount of said GA101 antibody once every dosing period during the co-administration and 2-(1H-pyrrolo[2,3-b]pyridin- 5-yloxy)-4-(4-(2-(4-chlorophenyl)-4,4-dimethylcyclohex-1-enyl)methyl)piperazin-1-yl)-N-(3-nitro-4-((tetrahydro-2H-pyran-4-yl)methylamino)phenylsulfonyl)benzamide or a pharmaceutically acceptable salt thereof one, two or three times a day during the co-administration for one or more dosing periods, followed by administering an effective amount of said GA101 antibody alone once every dosing period for 1, 2, 3, 4, 5 or 6 dosing periods.

4. The method of claim 1 , comprising co-administering an effective amount of said GA101 antibody once every dosing period during the co-administration and 2-(1H-pyrrolo[2,3-b]pyridin-5-yloxy)-4-(4-((2-(4-chlorophenyl)-4,4-dimethylcyclohex-1-enyl)methyl)piperazin-1-yl)-N-(3-nitro-4-((tetrahydro-2H-pyran-4-yl)methylamino)phenylsulfonyl)benzamide or a pharmaceutically acceptable salt thereof one, two or three times a day during the co-administration for one or more dosing periods, followed by administering an effective amount of 2-(1H-pyrrolo[2,3-b]pyridin-5-yloxy)-4-(4-((2-(4-chlorophenyl)-4,4-dimethylcyclohex-1-enyl)methyl)piperazin-1-yl)-N-(3-nitro-4-((tetrahydro-2H-pyran-4-yl)methylamino)phenylsulfonyl)benzamide or a pharmaceutically acceptable salt thereof alone one, two or three times a day for 1, 2, 3, 4, 5 or 6 dosing periods.
