Abemaciclib is a kinase inhibitor and is used for the following:

• Early breast cancer in people with a high risk of their cancer coming back Advanced or metastatic breast cancer

Abemaciclib is a specific type of kinase inhibitor, called a cyclin-dependent kinase 4 and 6 (CDK 4/6) inhibitor. CDK 4/6 are proteins that control cell growth in both normal and cancer cells. These proteins can become overactive in cancer cells and cause the cancer to uncontrollably divide and grow. By blocking CDK 4/6, Abemaciclib slows the growth of cancer cells.
