ASH 2022: Dr. James Blachly Discusses Results from a Phase 1/2 Dose Escalation and Expansion Study Evaluating MS-533, a Novel and Selective Protein Kinase C-Beta Inhibitor in Patients with Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL)
MS-553, a protein kinase C-beta (PKCß) inhibitor, is an exciting new agent in a yet-to-be-approved class of drugs that target an area of the B-cell receptor pathway independent of Bruton tyrosine kinase (BTK) and phospholipase C gamma 2 (PLCy2) mutations which confer resistance to BTK inhibitors.
