Abstract:Cyclin-dependent kinases (CDKs) 4/6 inhibitors are a powerful class of therapeutic drugs for the treatment of advanced metastatic breast cancer. However, the currently approved CDK4/6 inhibitors palbociclib, ribociclib and abemaciclib have dose-limiting toxicities that require treatment holidays or reductions to sub-optimal doses, thus limiting full target inhibition. The residual CDK4/6 activity, together with persistent signaling through CDK2/cyclin E are among key resistant mechanisms that can compromise fu… Show more
