What is Kisqali (ribociclib) for?
Kisqali (ribociclib) is a kinase inhibitor indicated in combination with an aromatase inhibitor as initial endocrine-based therapy for the treatment of postmenopausal women with hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative advanced or metastatic breast cancer1,2.
How does Kisqali (ribociclib) work?
Ribociclib is an inhibitor of cyclin-dependent kinase (CDK) 4 and 6. Before a cell can divide, it has to go through four phases: a growth phase (G1-phase), a synthesis phase (S-phase), another growth phase (G2-phase), and a last phase is where the cell divides (M-phase). Cancer cells divide exceedingly fast, passing through these 4 phases rapidly. Ribociclib blocks the progression from the first G1-phase, into the second S-phase. It does this by inhibiting the cyclin-dependent kinases 4 and 6 (CDK4 and CDK6) – two proteins that are involved in entering the S-phase1.
