Abstract

Patients with indolent non-Hodgkin lymphoma (iNHL) typically respond to first-line immunochemotherapy, but relapse is common. Treatment options for relapsed iNHL include chemotherapy ± rituximab and rituximab monotherapy. Lenalidomide plus rituximab (R2) is an immunomodulatory regimen that enhances rituximab-mediated cytotoxicity and improves clinical activity in iNHL. AUGMENT was a double-blind phase III randomized trial of R2 vs. rituximab + placebo (R-placebo) in patients with relapsed/refractory follicular lymphoma or marginal zone lymphoma who were not refractory to rituximab. The primary endpoint was progression-free survival (PFS). Data reported here focus on Japanese patients from AUGMENT and reflect 36 patients (n = 18, each group). PFS was superior in the R2 group, HR = 0.32 (95% CI 0.11-0.96). Median PFS was not reached (95% CI 19.7-NE) in the R2 group vs. 16.5 months (95% CI 11.3-30.6) in the R-placebo group. Grade 3/4 adverse events were more frequent in patients treated with R2 (67%) than with R-placebo (22%), primarily attributable to increased neutropenia (50% vs 17%). R2 resulted in significantly longer median PFS than R-placebo in Japanese patients with R/R iNHL, and the efficacy and the safety profile of R2 were similar to those reported in the global population.
