At diagnosis, patients had a median age of 64.5 years, 63.6% presentedwith intermediate/high sMIPI (simplified prognostic index for advanced-stage mantle cell lymphoma), 24.5% had theblastoid variant, and 55.6% had a Ki67 > 30%. Patients had received a median of 2 prior lines of therapy (range 1–2; min–max1–7). Overall response rate was 63.5%, with 38.1% of patients achieving complete response (CR). With a median duration ofibrutinib exposure of 10.7 months (range 5.2–19.6; min–max 0.3–36), the median progression-free survival (PFS) and overallsurvival (OS) were 20 months [95% confidence interval (CI) 8.8–31.1] and 32 months (95% CI 22.6–41.3), respectively, andwere not reached in patients achieving CR. No grade ≥ 3 cardiovascular toxicity or bleeding was reported. This study supportsthat treatment with ibrutinib leads to high response rates and favorable survival outcomes in patients with R/R MCL.
