Key clinical point: Second-line vs later-line zanubrutinib treatment leads to significantly improved long-term survival outcomes in patients with relapsed or refractory mantle cell lymphoma (MCL).
Major finding: At a median follow-up of 35.2 months, patients receiving second-line vs later-line zanubrutinib had significantly improved median overall survival (adjusted hazard ratio 0.459; P = .044) and numerically longer median progression-free survival (27.8 vs 22.1 months). Adverse events observed in both groups were consistent with the known safety profile of zanubrutinib.
Study details: Findings are from an updated pooled analysis of 112 patients from the BGB-3111-AU-003 and BGB-3111-206 clinical trials who had relapsed or refractory MCL and received second-line (n = 41) or later-line (n = 71) zanubrutinib.
