Abstract

For millions of women, breast cancer remains a potentially life-endangering diagnosis. With advances in research, new therapies targeted to tumor biology are emerging to treat the most common form of this disease. Cyclin-dependent kinase (CDK) 4/6 inhibitors are a new class of therapeutic agents that have the potential to improve the outcomes of patients with hormone receptor-positive (HR(+)) breast cancer. Three CDK 4/6 inhibitors have been investigated for the treatment of HR(+) breast cancer, including palbociclib (PD 0332991), ribociclib (LEE011), and abemaciclib (LY2835219). Palbociclib recently received accelerated Food and Drug Administration approval for the treatment of HR(+) metastatic breast cancer in combination with letrozole, and recent data suggest improved outcome when combined with fulvestrant. In this article, the mechanism of action of CDK 4/6 inhibitors, preclinical studies on their efficacy, ongoing clinical trials in breast cancer, and toxicity profiles are reviewed.

Keywords: Abemaciclib; CDK 4/6 inhibitors; Hormone receptor-positive breast cancer; Palbociclib; Ribociclib.
