  • Reduction in distant recurrence consistently deepened beyond 3-year Kisqali treatment duration in patients with node-positive (N+) and high-risk node-negative (N0) disease, as well as between anatomical stages1

  • Real-world 5-year distant recurrence data in high-risk patients with HR+/HER2- early breast cancer (EBC), regardless of nodal status, highlights importance of adding a CDK4/6 inhibitor to endocrine therapy for all eligible patients2

  • Late-breaking Kisqali data presentations at SABCS follow recent FDA and EMA approvals and recognition by NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines®*) as only Category 1 preferred adjuvant treatment for both N+ and high-risk N0 disease in combination with AI3

Basel, December 10, 2024 – Novartis today announced results from an updated analysis of the pivotal Phase III NATALEE trial of Kisqali® (ribociclib) that underscore the extended efficacy beyond the duration of treatment in combination with endocrine therapy (ET). Results showed a sustained reduction in distant recurrence of 28.5% (HR=0.715; 95% CI 0.604-0.847; nominal P<0.0001), compared to ET alone, in patients with stage II and III hormone receptor-positive/human epidermal growth factor receptor 2-negative (HR+/HER2-) early breast cancer (EBC)1.

Reduction in distant recurrence, known as distant disease-free survival (DDFS), is a decrease in the rate of cancer returning and spreading to other organs. The DDFS with Kisqali was consistent across all pre-specified patient subgroups, including those with node-negative (N0) disease1. These late-breaking data are being presented at the 2024 San Antonio Breast Cancer Symposium (SABCS).

"In day-to-day practice, we see a real and persistent risk of breast cancer coming back after early diagnosis, often as metastatic disease,” said Paolo Tarantino, M.D., Advanced Fellow at Dana-Farber Cancer Institute and Harvard Medical School. “The latest NATALEE and real-world data presented at SABCS reaffirm we can better address risk of recurrence for all patients at high-risk, including selected patients with node-negative disease, by offering them adjuvant CDK4/6 inhibitor treatment in addition to endocrine therapy.”

Safety remains consistent with previous reports, and no new safety signals were identified5. Adverse events (AEs) of special interest (grade 3 or higher) were neutropenia (44.4%), liver-related AEs (e.g., elevated transaminases) (8.6%), and QT interval prolongation (1.0%)5.
