Combinations of signal transduction inhibitors

The present invention relates to methods for treating cancer comprising utilizing a combination of signal transduction inhibitors. More specifically, the present invention relates to combinations of so called cell cycle inhibitors with mitogen stimulated kinase signal transduction inhibitors, more specifically combinations of CDK inhibitors with mitogen stimulated kinase signal transduction inhibitors, more preferably MEK inhibitors. Other embodiments of the invention relate to additional combinations of the aforesaid combinations with standard anti-cancer agents such as cytotoxic agents, palliatives and antiangiogenics. Most specifically this invention relates to combinations of 6-acetyl-8-cyclopentyl-5-methyl-2-(5-piperazin-1-yl-pyridin-2-ylamino)-8H-pyrido[2,3-d]pyrimidin-7-one including salt forms, which is a selective cyclin-dependent kinase 4 (CDK4) inhibitor, in combination with one or more MEK inhibitors, most preferably N-[(R)-2,3-dihydroxy-propoxy]-3,4-difluoro-2-(2-fluoro-4-iodo-phenylamino)-benzamide. The aforementioned combinations are useful for treating inflammation and cell proliferative diseases such as cancer and restenosis.

Companion diagnostic for cdk4 inhibitors

The present invention relates to the use of one or more biomarkers to evaluate the likelihood that a CDK4 inhibitor would produce an anti-cancer effect in a subject. It is based, at least in part, on the discovery that cancer treatment with a CDK4 inhibitor is more effective where treated cancer cells undergo cellular senescence rather than a transient cell cycle arrest, where cellular senescence is associated with decreased MDM2 protein level. Accordingly, in non-limiting embodiments, the present invention provides for methods, compositions, and kits for a companion diagnostic for CDK4 inhibitors, and in particular, to the use of MDM2 expression as a biomarker for the likelihood that a cancer can be successfully treated by CDK4 inhibition.
