European Commission approves Kisqali (ribociclib) with an aromatase inhibitor for the adjuvant treatment of HR-positive, HER2-negative early breast cancer – Novartis

 Novartis announced that  the European Commission (EC) has approved Kisqali (ribociclib) in combination with an aromatase inhibitor (AI) for the adjuvant treatment of patients with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative early breast cancer (EBC) at high risk of recurrence. The approval is based on results from the pivotal Phase III NATALEE trial, which included a broad patient population with HR+/HER2- stage II and III EBC, including those with node-negative disease. The trial showed a significant and clinically meaningful 25.1% (HR=0.749; 95% CI: 0.628, 0.892; P=0.0006) reduction in risk of disease recurrence with adjuvant Kisqali plus endocrine therapy (ET) compared to ET alone. The invasive disease-free survival (iDFS) benefit was consistently observed across all patient subgroups.

“For many patients diagnosed with stage II or III HR+/HER2- early breast cancer, the risk of their cancer coming back despite treatment with endocrine therapy remains high, even after decades,” said Michael Gnant, M.D., FACS, FEBS, Professor of Surgery at the Medical University of Vienna, Austria, and President of the Austrian Breast and Colorectal Study Group. “This approval represents a positive milestone for the early breast cancer community in Europe, including physicians who now have a new option to help reduce the risk of recurrence in a broader population of patients.”

In addition, Michael Untch, M.D., Professor and Head of the Clinic for Gynecology and Obstetrics, and Director of the Interdisciplinary Breast Cancer Center at Helios Klinikum Berlin-Buch, noted: “Adding a new treatment option to the HR+/HER2- early breast cancer armamentarium is encouraging news for both physicians and their patients – including patients with node-negative disease and additional risk factors. Ribociclib may now help many patients who are at risk of their cancer returning.”

Breast cancer is the most commonly diagnosed cancer in Europe, with approximately 70% of cases diagnosed in the early stages of the disease. Despite current treatment options, people with stage II and III HR+/HER2- EBC remain at risk of experiencing a return of their cancer in the long term, often as incurable advanced disease.

“Breast cancer recurrence can be a lifelong concern for those living with the disease. Patients deserve access to treatment options that help minimize the risk of their cancer coming back and put their mind at ease,” said Iris Zemzoum, M.D., President, Europe, Novartis. “We are proud of this approval, which will help to address a key unmet need and improve health outcomes for a broader population of patients in Europe.”
