Combination of an anaplastic lymphoma kinase inhibitor and a cyclin dependent kinase inhibitor
This invention relates to combination therapies comprising an inhibitor of anaplastic lymphoma kinase (ALK) and, an inhibitor of cyclin dependent kinase 4 and 6 (CDK4/6 inhibitor) or an inhibitor of cyclin dependent kinase 2, 4 and 6 (CDK2/4/6 inhibitor), and associated methods of treatment, combinations, pharmaceutical compositions and uses thereof.
1 . A method of treating lung cancer in a subject comprising administering to the subject an amount of an anaplastic lymphoma kinase (ALK) inhibitor and an amount a cyclin dependent kinase (CDK) inhibitor, wherein the CDK inhibitor is an inhibitor of CDK4 and CDK6 (CDK4/6 inhibitor) which is palbociclib, or an inhibitor of CDK2, CDK4 and CDK6 (CDK2/4/6 inhibitor) which is 6-(difluoromethyl)-8-((1R,2R)-2-hydroxy-2-methylcyclopentyl)-2-(1-(methylsulfonyl)piperidin-4-ylamino)pyrido[2,3-d]pyrimidin-7 (8H)-one, and wherein the amounts together are effective in treating cancer, wherein the ALK inhibitor is lorlatinib, or a pharmaceutically acceptable salt thereof.
2 . The method of claim 1 , wherein the ALK inhibitor and the CDK inhibitor are administered sequentially, simultaneously, or concurrently.
3 . A method of treating lung cancer in a subject comprising administering to the subject an amount of lorlatinib, or a pharmaceutically acceptable salt thereof, and an amount of palbociclib, or a pharmaceutically acceptable salt thereof, wherein the amounts together are effective in treating cancer.
4 . A method of treating lung cancer in a subject comprising administering to the subject an amount of lorlatinib, or a pharmaceutically acceptable salt thereof, and an amount of 6-(difluoromethyl)-8-((1R,2R)-2-hydroxy-2-methylcyclopentyl)-2-(1-(methylsulfonyl)piperidin-4-ylamino)pyrido[2,3-d]pyrimidin-7 (8H)-one, or a pharmaceutically acceptable salt thereof, wherein the amounts together are effective in treating cancer.
5 . A combination comprising, separately or together, an ALK inhibitor and a CDK inhibitor, wherein the ALK inhibitor is lorlatinib, or a pharmaceutically acceptable salt thereof, and wherein the CDK inhibitor is a CDK4/6 inhibitor which is palbociclib, or a CDK2/4/6 inhibitor which is 6-(difluoromethyl)-8-((1R,2R)-2-hydroxy-2-methylcyclopentyl)-2-(1-(methylsulfonyl)piperidin-4-ylamino)pyrido[2,3-d]pyrimidin-7 (8H)-one.
6 . The combination of claim 5 , for use in the treatment of lung cancer in a subject.
7 . The combination of claim 5 , wherein the combination is a synergistic combination.
8 . A pharmaceutical composition comprising lorlatinib, or a pharmaceutically acceptable salt thereof, palbociclib, or a pharmaceutically acceptable salt thereof, and at least one pharmaceutically acceptable excipient.
9 . A pharmaceutical composition comprising lorlatinib, or a pharmaceutically acceptable salt thereof, 6-(difluoromethyl)-8-((1R,2R)-2-hydroxy-2-methylcyclopentyl)-2-(1-(methylsulfonyl)piperidin-4-ylamino)pyrido[2,3-d]pyrimidin-7 (8H)-one, or a pharmaceutically acceptable salt thereof, and at least one pharmaceutically acceptable excipient.
