Medication Class: Cyclin-dependent kinase (CDK) 4 and 6 inhibitor

What is Kisqali and how does it work?

Kisqali (ribociclib) is a cyclin-dependent kinase (CDK) inhibitor approved for the treatment of postmenopausal women with hormone receptor positive (HR-positive), human epidermal growth factor receptor 2 negative (HER2-negative) advanced or metastatic breast cancer. It is used in combination with Femara (letrozole).

Under normal conditions, CDK4 and CDK6 help regulate cell division in the human body. However, these proteins can become over-activated in certain breast cancer patients, leading to uncontrolled cell division. These breast cancer cells can continue to divide and spread rapidly if left untreated. Kisqali slows the growth of breast cancer cells and prevents their spread by blocking the action of CDK4 and CDK6.

What is Kisqali used for treating?

Kisqali (ribociclib) is used in combination with an aromatase inhibitor to treat postmenopausal women with hormone receptor positive, human epidermal growth factor receptor-2 (HER2)-negative advanced or metastatic breast cancer

How effective is Kisqali?

A randomized, double-blind, placebo-controlled, multicenter study evaluated the effects of Kisqali plus letrozole versus placebo plus letrozole in 668 postmenopausal women with HR-positive, HER2-negative, advanced breast cancer who received no prior therapy for advanced cancer. The dose of Kisqali was 600 mg daily for 21 days followed by 7 days off. Letrozole 2.5 mg was given the entire 28-day cycle.

Kisqali plus letrozole reduced the risk of cancer progression or death by 44% compared to letrozole alone. The median progression-free survival was 25.3 months for patients who received Kisqali plus letrozole and 16 months for the placebo plus letrozole group.
