Pirtobrutinib in Chinese patients with relapsed or refractory B-cell malignancies: A single-arm, open-label, phase 2, multicenter trial.

ABSTRACT: Pirtobrutinib, a highly selective, noncovalent (reversible) Bruton tyrosine kinase inhibitor (BTKi), demonstrated clinically meaningful antitumor responses in covalent BTKi pretreated mantle cell lymphoma (MCL) and chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL) in the global phase 1/2 BRUIN study. In this multi-center, open-label, phase 2 trial, we investigated the efficacy and safety of pirtobrutinib in Chinese patients with BTKi pretreated relapsed/refractory (R/R) MCL, CLL/SLL, or other B-cell malignancies. All patients received pirtobrutinib once daily in continuous 28-day cycles. The primary endpoint was the overall response rate (ORR). Efficacy was assessed in patients with MCL and CLL/SLL with prior BTKi treatment and safety in all enrolled patients who recei
