Abstract
- Background: Ibrutinib has revolutionized the treatment of mantle cell lymphoma (MCL). Both ibrutinib monotherapy and ibrutinib‐based combination therapy are important salvage options for patients with relapsed/refractory (R/R) MCL. The real‐world efficacy and safety profile of the two strategies in Chinese patients with R/R MCL remain unclarified. Methods: In the present study, data of 121 R/R MCL patients who received either ibrutinib monotherapy (N = 68) or ibrutinib combination therapy (N = 53) in 13 medical centers in China were retrospectively reviewed. Results: With a median follow‐up of 20.5 months, the overall response rate was 60.3% versus 84.9% (p = 0.003), complete remission rate was 16.2% versus 43.4% (p < 0.001), and median progression‐free survival (PFS) was 18.5 months (95% confidence interval [CI], 12.1–21.8) vs. 30.8 months (95% CI, 23.5‐NR) (hazard ratio, 0.53 [95% CI, 0.30–0.93]; p = 0.025), with ibrutinib monotherapy and ibrutinib‐based combination therapy, respectively. Subgroup analysis showed that patients with male gender, no refractory disease, Ki67 <30%, previous line of therapy = 1, non‐blastoid subtype, and the number of extranodal sites involved <2 might benefits more from the combination therapy. Treatment‐emergent adverse events were similar, except for a higher incidence of all grade neutropenia in the ibrutinib combination group (12.7% vs. 32.0%, p = 0.017). Conclusions: Ibrutinib combination therapy demonstrated potentially superior efficacy and comparable tolerability to ibrutinib monotherapy. Ibrutinib‐based combination therapy could be one of the prominent treatment options for R/R MCL patients. [ABSTRACT FROM AUTHOR]
