Key clinical point: The clinical benefit of ribociclib is maintained in patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced breast cancer who required dose reduction to manage adverse events.
Major finding: Ribociclib dose reductions were reported in 45.8% of patients; most were attributed to adverse reactions. The median progression-free survival was 24.8, 24.9, and 29.6 months for patients who received 71% or less, 72%-96%, and 97%-100% ribociclib relative dose intensity, respectively. The clinical benefit ratio was 87.6%, 76.8%, and 73.6%, respectively.
Study details: A pooled analysis of MONALEESA-2, MONALEESA-3, and MONALEESA-7 trials evaluated the safety and impact of ribociclib dose reduction in 818 patients with HR-positive, HER2-negative advanced breast cancer.
Disclosures: The study was supported by Novartis Pharmaceuticals Corporation. The authors received grants, funding, and/or consulting/advisory/personal fees from various sources. Dr. JP Zarate, Dr. A Ridolfi, and Dr. KR Lorenc were employed by and owned stocks in Novartis.
