In a multicentre, open-label, phase 1/2 BRUIN trial, pirtobrutinib demonstrated meaningful response rates and durable efficacy in patients with heavily pretreated (including a covalent BTK inhibitor) relapsed or refractory MCL. Pirtobrutinib had a manageable tolerability profile, with most treatment related adverse events being mild to moderate in severity. Longer term, the tolerability profile of pirtobrutinib revealed no new safety signals. © Springer Nature Switzerland AG 2024
