FDA Approval: Ribociclib for the Treatment of Postmenopausal Women with Hormone Receptor-Positive, HER2-Negative Advanced or Metastatic Breast Cancer

On March 13, 2017, the U.S. Food and Drug Administration approved ribociclib (KISQALI, Novartis Pharmaceuticals Corp.), a cyclin-dependent kinase 4/6 inhibitor, in combination with an aromatase inhibitor as initial endocrine-based therapy for the treatment of postmenopausal women with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced or metastatic breast cancer. The approval was based on a randomized, double-blind, placebo-controlled, international clinical trial (MONALEESA-2). A total of 668 patients were randomized to receive either ribociclib plus letrozole (n=334) or placebo plus letrozole (n=334). An improvement in progression free survival (PFS) was observed in patients receiving ribociclib plus letrozole compared with patients receiving placebo plus letrozole (HR 0.556; 95% confidence interval, 0.429-0.720). Overall response rate (ORR) in patients with measurable disease was 52.7% (95% CI: 46.6, 58.9) in the ribociclib plus letrozole arm and 37.1% (95% CI: 31.1, 43.2) in the placebo plus letrozole arm. Overall survival data were immature. The most common adverse reactions observed in 20% or more of patients taking ribociclib were neutropenia, nausea, fatigue, diarrhea, leukopenia, alopecia, vomiting, constipation, headache, and back pain. This article summarizes FDA decision-making and data supporting the approval of ribociclib.
