Description:

WARNING: This product is for research use only, not for human or veterinary use.

Trilaciclib is a potential first-in-class short-acting CDK4/6 inhibitor in development to preserve hematopoietic stem cells and enhance immune system function during chemotherapy. Trilaciclib may help protect bone marrow cells from damage caused by chemotherapy by inhibiting cyclin-dependent kinase 4/6, a type of enzyme. Trilaciclib is the first therapy in its class and was approved for medical use in the United States in February 2021.
