Rx Profiler – Abemaciclib (Verzenio™), a Novel CDK4/6 Inhibitor, in the Treatment of Hormone Receptor–Positive, HER2-Negative Advanced Breast Cancer
Metastatic breast cancer (MBC) or advanced breast cancer (ABC) signifies that cancer has spread to a distant organ site, either as a progression or a recurrence after a patient has first been diagnosed with an earlier stage of breast cancer. Alternatively, in the case of de novo MBC, MBC or ABC is staged as being metastatic or stage IV at diagnosis.
Breast cancer is the most common cancer in women and remains a leading cause of cancer-related morbidity, mortality, and resource utilization. For patients with advanced breast cancer, prognosis remains especially suboptimal, primarily because of acquired pharmacologic resistance.
