WebPotential Prospect of CDK4/6 Inhibitors in Triple-Negative Breast Cancer. Abstract: Triple-negative breast cancer (TNBC) is an aggressive, difficult-to-treat subtype of cancer with a poor prognosis; there is an urgent need for effective, targeted molecular therapies. The cyclin D/cyclin-dependent kinase (CDK)4/6–retinoblastoma protein (Rb ... WebSince 2015, three CDK 4/6 inhibitors have been approved for treatment of hormone receptor-positive HER2-negative metastatic breast cancer: palbociclib, ribociclib and abemaciclib. These drugs share a common mechanism of action and have been evaluated in studies with a similar design. A CDK (cyclin-dependent kinase) inhibitor is any chemical that inhibits the function of CDKs. They are used to treat cancers by preventing overproliferation of cancer cells. The US FDA approved the first drug of this type, palbociclib (Ibrance), a CDK4/6 inhibitor, in February 2015, for use in postmenopausal women with breast cancer that is estrogen receptor positive and HER2 negative. Several compounds are in clinical trials. or acorn\u0027s
