Ribociclib (Kisqali): Mechanism of Action and Clinical Trials

Introduction

Ribociclib, also known as Kisqali, is a selective cyclin-dependent kinase inhibitor with a mechanism of action that inhibits proteins crucial for cancer cell growth.​ Clinical trials have demonstrated its efficacy in treating various tumor types, especially advanced breast cancer.​ 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.
