The podcast provides significant updates on the use of BTK inhibitors in the treatment of chronic lymphocytic leukemia (CLL). Jeff Sharman discusses the Phase 3 Bruin CLL321 trial, comparing pirtabrutinib, a non-covalent BTK inhibitor, against standard therapies like idelalisib and rituximab. Results show a median progression-free survival of 14 months for pirtabrutinib versus 8.5 months for the other therapies, suggesting substantial benefits in challenging patient populations. Notably, over 50% of the trial participants had TP53 abnormalities, indicating that pirtabrutinib can be particularly effective even in patients with complex genetic backgrounds.
