Breast cancer is the most commonly diagnosed cancer in Europe 7 . HR+/HER2- is the most common subtype, accounting for approximately 70% of all breast cancers, and more than 40% of these are diagnosed in stage II or III 8-10 .
The positive CHMP decision is based on robust data from the Phase III NATALEE trial 2,11,12 . In the trial, Kisqali plus endocrine therapy (ET), compared to ET alone, lowered the risk of cancer recurrence by 25.1% in patients with stage II and III HR+/HER2- EBC (HR=0.749; 95% CI: 0.628, 0.892; P =0.0006) and demonstrated a consistent, clinically meaningful invasive disease-free survival (iDFS) benefit across key pre-specified subgroups 2,11 . Data from the pivotal trial also showed the safety profile of Kisqali at the 400mg dose was well-tolerated with generally low-grade symptomatic adverse events 2,11 .
An updated analysis from the NATALEE trial recently presented at the European Society for Medical Oncology (ESMO) Congress 2024 adds to the growing body of evidence supporting the potential of Kisqali to consistently reduce risk of recurrence across a broad population 6 . In the updated analysis, the iDFS benefit continued to deepen beyond the three-year Kisqali treatment period in all patient subgroups, including those with node-negative disease 2 .
"Today, many people diagnosed with HR+/HER2- early breast cancer in Europe lack options beyond endocrine therapy to help reduce their risk of cancer coming back. If approved, Kisqali could nearly double the number of patients eligible for CDK4/6 inhibitor adjuvant therapy," said Patrick Horber M.D ., President, International, Novartis. "Together with the recent FDA approval and late-breaking NATALEE data presented at ESMO, today's positive CHMP recommendation further reinforces the differentiated profile of Kisqali as a new treatment option for a broad population of patients, including those with node-negative disease."
Following the CHMP's recommendation to approve Kisqali in a broad population of patients diagnosed with HR+/HER2- EBC at high risk of recurrence, the European Commission (EC) will take a final decision within approximately two months.
About NATALEE
NATALEE is a global Phase III multi-center, randomized, open-label trial to evaluate the efficacy and safety of Kisqali ® (ribociclib) with ET as an investigational adjuvant treatment versus ET alone in patients with stage II and III HR+/HER2- EBC, being conducted in collaboration with TRIO 2,13 . The adjuvant ET in both treatment arms was a non-steroidal aromatase inhibitor (NSAI; anastrozole or letrozole) and goserelin if applicable 2,13 . The primary endpoint of NATALEE is invasive disease-free survival (iDFS) as defined by the Standardized Definitions for Efficacy End Points (STEEP) criteria 2,13 . A total of 5,101 adult patients with HR+/HER2- EBC across 20 countries were randomized in the trial 2,13 .
About Kisqali ® (ribociclib)
Kisqali ® (ribociclib) is a selective cyclin-dependent kinase inhibitor, a class of drugs that help slow the progression of cancer by inhibiting two proteins called cyclin-dependent kinase 4 and 6 (CDK4/6). These proteins, when over-activated, can enable cancer cells to grow and divide too quickly. Targeting CDK4/6 with enhanced precision may play a role in ensuring that cancer cells do not continue to replicate uncontrollably.
Kisqali was approved as a treatment for early breast cancer by the U.S. Food and Drug Administration (FDA) in September 2024 5 . Regulatory reviews for Kisqali as an EBC treatment are ongoing worldwide, including in the EU and China .
Kisqali has been approved as a treatment for metastatic breast cancer (MBC) patients in 99 countries worldwide, including by the U.S. FDA and the European Commission 14,15 . In the U.S., Kisqali is indicated for the treatment of adults with HR+/HER2- advanced or MBC in combination with an AI as initial ET or fulvestrant as initial ET or following disease progression on ET in post-menopausal women or in men 14 . In the EU, Kisqali is approved for the treatment of women with HR+/HER2- advanced or MBC in combination with either an AI or fulvestrant as initial ET or following disease progression 15 . In pre- or peri-menopausal women, the ET should be combined with a luteinizing hormone-releasing hormone agonist 14,15 .
In MBC, Kisqali has consistently demonstrated statistically significant overall survival benefit across three Phase III trials 16-26 . The NCCN Guidelines ® for breast cancer recommend ribociclib (Kisqali) as the only Category 1 preferred CDK4/6 inhibitor for first-line treatment of people living with HR+/HER2- when combined with an AI, making Kisqali the preferred first-line treatment of choice for US prescribers in HR+/HER2- MBC 27 . Additionally, Kisqali has the highest rating of any CDK4/6 inhibitor on the ESMO Magnitude of Clinical Benefit Scale, achieving a score of five out of five for first-line pre-menopausal patients with HR+/HER2- advanced breast cancer 28 . Further, Kisqali in combination with either letrozole or fulvestrant has uniquely, among other CDK4/6 inhibitors, received a score of four out of five for post-menopausal patients with HR+/HER2- advanced breast cancer treated in the first line 29 .
Kisqali was developed by Novartis under a research collaboration with Astex Pharmaceuticals.

Indication
What is KISQALI?
KISQALI ® (ribociclib) is a prescription medicine used to treat adults with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative breast cancer:
- in combination with an aromatase inhibitor for stage II and III early breast cancer with a high risk of coming back
- that has gotten worse or has spread to other parts of the body (advanced or metastatic breast cancer) in combination with:
- an aromatase inhibitor as the first endocrine-based therapy; or
- fulvestrant as the first endocrine-based therapy or following disease progression on endocrine therapy
It is not known if KISQALI is safe and effective in children.
IMPORTANT SAFETY INFORMATION
KISQALI may cause serious side effects, including:
Lung problems. KISQALI may cause severe or life-threatening inflammation of the lungs during treatment that may lead to death. Tell your health care provider right away if you have any new or worsening symptoms, including:
- trouble breathing or shortness of breath
