Clinicians discussed BTK inhibitor use in CLL, follicular lymphoma, and MCL, focusing on frontline management, sequencing therapies, and managing AEs. They debated treatment options, including BTK inhibitor monotherapy vs. venetoclax and obinutuzumab, and the efficacy of newer BTK inhibitors like acalabrutinib and zanubrutinib. The panel also addressed real-world data on therapy switching and the impact of BTK inhibitors on vaccine responses.
