Drug Overview
Abemaciclib is a small molecule inhibitor of cyclin-dependent kinase (CDK)4 and CDK6 in Phase III development for non-small cell lung cancer and hormone receptor-positive/human epidermal growth factor receptor 2-negative breast cancer by Eli Lilly. In normal tissues, CDK4/6 associate with cyclin-D proteins to phosphorylate and inactivate the retinoblastoma 1 (RB1) tumor suppressor protein, thereby releasing transcription factors needed for DNA replication and subsequent progression through the cell cycle. CDK4/6 are attractive targets as dysregulation of the cell cycle through genetic alterations is a hallmark of several cancers, including breast cancer. Inhibiting the phosphorylation of RB1 arrests cell growth in the G1 phase, preventing further cell growth and proliferation in malignant tissues.
