Real-world evidence supports its effectiveness, safety, and tolerability in routine clinical practice, making it a promising therapeutic option.
Overview of Ribociclib (Kisqali)
Ribociclib, known by the brand name Kisqali, is a selective cyclin-dependent kinase inhibitor that acts by inhibiting proteins critical for cancer cell proliferation. Approved for HR /HER2- advanced breast cancer٫ ribociclib has demonstrated efficacy and safety in clinical trials and real-world use. With a manageable tolerability profile٫ this drug shows therapeutic potential across various tumor types and has been studied in combination therapies to enhance clinical activity.
Mechanism of Action
Ribociclib, a potent selective cyclin-dependent kinase inhibitor, impedes cancer cell proliferation by targeting cyclin-dependent kinase 4/6 proteins. This inhibition disrupts the cyclin D-CDK4/6 complex, halting cell cycle progression and impeding tumor growth. By suppressing these critical proteins, ribociclib demonstrates its therapeutic efficacy in inhibiting tumor cell proliferation and offers a promising approach to cancer treatment.
Inhibition of Cyclin-Dependent Kinases 4/6
Ribociclib acts as a potent inhibitor of cyclin-dependent kinases 4 and 6, key regulators of the cell cycle. By disrupting the cyclin D-CDK4/6 complex, ribociclib effectively halts cell cycle progression, impairing the proliferation of cancer cells. This targeted inhibition of CDK4/6 demonstrates promising antitumor activity and provides a strategic approach to cancer treatment.
