Novartis Kisqali significantly extends life in women with HR+/HER2- advanced breast cancer in MONALEESA-7 trial

In This Article:

  • Kisqali is the only CDK4/6 inhibitor to show superior overall survival in advanced breast cancer (HR=0.712; p=0.00973)[1]

  • After a median of 42 months follow-up, the survival rate was 70.2% for women who received Kisqali combination therapy compared to 46.0% for women who received endocrine therapy alone[1]

  • Advanced breast cancer in premenopausal women is the leading cause of cancer death in women 20-59 years old[2],[3]

  • MONALEESA-7 overall survival results will be presented as a late-breaker at the 2019 ASCO Annual Meeting and will be published in The New England Journal of Medicine

Basel, June 1, 2019 - Novartis today announced statistically significant overall survival (OS) results for Kisqali in combination with endocrine therapy[1]. The Phase 3 MONALEESA-7 trial evaluated Kisqali plus endocrine therapy (goserelin plus either an aromatase inhibitor or tamoxifen) as initial treatment compared to endocrine therapy alone in pre- and perimenopausal women with hormone receptor positive, human epidermal growth factor receptor-2 negative (HR+/HER2-) advanced or metastatic breast cancer[1]. MONALEESA-7 overall survival results will be featured in a press briefing today, presented as a late-breaker at the 2019 American Society of Clinical Oncology (ASCO) Annual Meeting (Abstract# LBA1008), and will be published in The New England Journal of Medicine.

The significant extension in survival met the early efficacy stopping criteria at a pre-specified interim analysis following 192 deaths (median OS, not reached vs. 40.9 [95% CI: 37.8-NE] months; HR=0.712 [0.535-0.948]; p=0.00973). Overall survival rates in the intent-to-treat population (n=672) at 42 months were 70.2% for Kisqali combination therapy compared to 46.0% for endocrine therapy alone. At the time of data cut-off, 35% of women taking Kisqali combination therapy were continuing the treatment. No new safety signals were observed[1]. Kisqali is not indicated for use with tamoxifen.

"Overall survival benefit is considered the `gold standard` in cancer trials but is challenging to achieve in HR+/HER2- metastatic breast cancer. MONALEESA-7 reached this important endpoint earlier than anticipated," said Sara Hurvitz, MD, Medical Director of the Jonsson Comprehensive Cancer Center Clinical Research Unit and Director of the Breast Cancer Clinical Trials Program at UCLA. "Impactful results like these ribociclib findings are what we wish for in every clinical trial, and to achieve overall survival improvement in an incurable disease, like metastatic breast cancer, is truly an outstanding advancement for patients."
