BTK inhibitors

Dr. Jennifer A. Woyach discusses promising phase III study findings at ASH 2025, revealing that the non-covalent BTK inhibitor pirtobrutinib is as effective as ibrutinib, while demonstrating less toxicity, in patients with relapsed/refractory and treatment-naïve chronic lymphocytic leukemia/small lymphocytic lymphoma. This first randomized head-to-head comparison shows pirtobrutinib met its primary endpoint of non-inferiority for overall response rate.
