The present invention provides a combination therapy comprising the compound 4-[4-[4-(4-fluoro-3-trifluoromethyl-phenyl)-1-methyl-1H-imidazol-2-yl]-piperidin-1-yl]-1H-pyrazolo[3,4-d]pyrimidine, or a pharmaceutically acceptable salt thereof, and an EGFR inhibitor for use in the treatment of glioblastoma multiforme, adenocarcinomas of the colon, non-small-cell lung cancer, small-cell lung cancer, cisplatin-resistant small-cell lung cancer, ovarian cancer, leukemia, pancreatic cancer, prostate cancer, mammary carcinoma, renal cell carcimoma, multiple myeloma, Kaposis Sarcoma, Hodgkins lymphoma, lymphangioleiomyomatosis, Non-Hodgkins lymphoma or sarcoma.
1. A method of treating a cancer selected from the group consisting of non-small-cell lung cancer, small-cell lung cancer, and cisplatin-resistant small-cell lung cancer comprising administering to a patient in need thereof a compound 4-[4-[4-(4-fluoro-3-trifluoromethyl-phenyl)-1-methyl-1H-imidazol-2-yl]-piperidin-1-yl]-1H-pyrazolo[3,4-d]pyrimidine, or a pharmaceutically acceptable salt thereof, and an EGFR inhibitor in amounts that in combination are effective.
2. The method according to claim 1 wherein the EGFR inhibitor is erlotinib hydrochloride.
3. The method according to claim 1 wherein the compound 4-[4-[4-(4-fluoro-3-trifluoromethyl-phenyl)-1-methyl-1H-imidazol-2-yl]-piperidin-1-yl]-1H-pyrazolo[3,4-d]pyrimidine, or a pharmaceutically acceptable salt thereof, is 4-[4-[4-(4-fluoro-3-trifluoromethyl-phenyl)-1-methyl-1H-imidazol-2-yl]-piperidin-1-yl]-1H-pyrazolo[3,4-d]pyrimidine tosylate.
4. The method according to claim 1 wherein the compound 4-[4-[4-(4-fluoro-3-trifluoromethyl-phenyl)-1-methyl-1H-imidazol-2-yl]-piperidin-1-yl]-1H-pyrazolo[3,4-d]pyrimidine, or a pharmaceutically acceptable salt thereof, and the EGFR inhibitor are administered orally.
5. A pharmaceutical composition comprising a compound 4-[4-[4-(4-fluoro-3-trifluoromethyl-phenyl)-1-methyl-1H-imidazol-2-yl]-piperidin-1-yl]-1H-pyrazolo[3,4-d]pyrimidine, or a pharmaceutically acceptable salt thereof, and an EGFR inhibitor.
6. The pharmaceutical composition of claim 5 wherein the EGFR inhibitor is erlotinib hydrochloride.
