European Society for Medical Oncology Magnitude of Clinical Benefit Scale (ESMO-MCBS)
Indications:1
KISQALI® (ribociclib) is indicated for the treatment of women with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative locally advanced or metastatic breast cancer in combination with an aromatase inhibitor or fulvestrant as initial endocrine-based therapy, or in women who have received prior endocrine therapy
In pre- or perimenopausal women, the endocrine therapy should be combined with a luteinising hormone-releasing hormone (LHRH) agonist
KISQALI is not recommended to be used in combination with tamoxifen.
To learn more about the safety profile of KISQALI, visit our portal page here.
For full safety profile information, please refer to the KISQALI Summary of Product Characteristics.
The ESMO-Magnitude of Clinical Benefit Scale (ESMO-MCBS) is a standardised tool that quantifies the likely magnitude of clinical benefit. The scale considers overall survival, progression-free survival, disease-free survival, hazard ratio, response rate, quality of life, prognosis of the condition and toxicity, of patients in the non-curative setting, ranging from grades 1 to 5, with 4 and 5 denoting substantial benefit.2
For further information, please refer to the ESMO-MCBS scorecard methodology.2
ESMO-MCBS: Scoring KISQALI
ESMO clinical practice guidelines:
KISQALI received an ESMO-MCBS rating of 4/5 when used in combination with LHRH and with ET3
As per the MONALEESA-7 trial, ET was defined as a non-steroidal aromatase or tamoxifen1,4
KISQALI is not recommended to be used in combination with tamoxifen.1
KISQALI + AI holds a rating of 4/5 as 1L treatment of postmenopausal patients with HR+/HER2− aBC3
KISQALI + fulvestrant holds a rating of 4/5 as 1L/2L treatment of postmenopausal patients with HR+/HER2− aBC3
The ESMO-MCBS was developed to promote the scientific integrity of ESMO and of oncologists, and in particular to:5
Reduce bias in data interpretation and analysis and enhance critical appraisal of the evidence
Reduce hype
Provide robust validation with strict adherence to standards for ‘accountability for reasonableness’
For the full safety profile, please refer to the KISQALI Summary of Product Characteristics.

Discover the safety profile of KISQALI + ET1,5,6
ET is defined as AI or fulvestrant1,6,7
KISQALI is not recommended to be used in combination with tamoxifen.1
Across all three MONALEESA trials, progression-free survival was the primary endpoint, overall survival and quality of life were the secondary endpoints.4,8,9
