Patients with chronic lymphocytic leukemia who experience disease progression during treatment with either covalent or noncovalent BTK inhibitors displayed a higher frequency of BTK mutations in L528W as well as RAS/RAF/MAPK pathway alterations, indicating that these alterations may play a role in the development of BTK inhibitor resistance.
The undetectable minimal residual disease ate achieved with bendamustine followed by obinutuzumab, acalabrutinib, and venetoclax increased as the regimen was continued as maintenance treatment in patients with relapsed or refractory chronic lymphocytic leukemia.
Monica D. Mead, MD, discusses the evolving use of the BTK inhibitors in the treatment of patients with MCL, the factors for selecting between ibrutinib, zanubrutinib, and acalabrutinib, and unmet needs for patients with MCL
Nirav Shah, MD, discusses the efficacy of pirtobrutinib in patients with mantle cell lymphoma who were previously treated with a covalent BTK inhibitor and progressed, and outlines the next steps for exploration of the noncovalent BTK inhibitor in this population.
