Abemaciclib (Verzenio®)

Abemaciclib is used to treat hormone receptor–positive/HER2-negative breast cancer when it is early-stage with a high risk of recurring or metastatic. It’s a CDK4/6 inhibitor, which means it prevents the proteins CDK4 or CDK6 from encouraging breast cancer cells to grow. It is given orally and can be used alone or with hormone therapy.
