Abstract

Older patients with diffuse large B-cell lymphoma (DLBCL) present unfavorable genetic and microenvironmental alterations. In this phase 2 trial, we assessed the efficacy and safety of zanubrutinib in combination with rituximab and lenalidomide (ZR2) in patients with de novo DLBCL aged ≥75 years. Forty patients were enrolled, and the primary end point was the complete response rate, which was 65.0% (95% confidence interval [CI], 48.3-78.9) at the end of induction treatment. The 2-year progression-free and overall survival rates were 67.1% (95% CI, 50.1-79.4) and 82.4% (95% CI, 66.5-91.2). The most common grades 3 and 4 hematologic adverse event (AE) was neutropenia (n = 14 [35.0%]). The most common grades 3 and 4 nonhematologic AEs were increased alanine transaminase (n = 5
