About Dinaciclib and Refractory Chronic Lymphocytic Leukemia

Dinaciclib is a pro-apoptotic inhibitor of cyclin-dependent kinases being evaluated by Merck in a Phase 2b/3 clinical trial for the potential treatment of patients with refractory CLL. CLL is a slow-progressing disease, affecting the blood and bone marrow, as well as the lymph nodes or other organs, and is the most common type of leukemia affecting adults1. Dinaciclib is derived from a collaboration initiated in 1998 by Pharmacopeia (now a wholly owned subsidiary of Ligand). More information about the trial can be found at
