ibrutinib

Othman Al-Sawaf MD PhD, a hematologist from University Hospital of Cologne, presents early data from the CLL17 international phase three trial at ASH 2025. The findings indicate that fixed-duration treatment with venetoclax plus obinutuzumab or venetoclax plus ibrutinib is non-inferior to continuous ibrutinib for patients with previously untreated chronic lymphocytic leukemia, potentially becoming the preferred treatment.

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.
