Atezolizumab consolidation in patients with high-risk diffuse large B-cell lymphoma in complete remission after R-CHOP.

Abstract

The risk of relapse among high-risk patients with diffuse large B-cell lymphoma (DLBCL) in complete metabolic remission (CMR) after rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone (R-CHOP) therapy is 20% to 25%. Here, we evaluated whether consolidation with the programmed cell death ligand 1 checkpoint inhibitor atezolizumab could reduce the relapse risk. In this phase 2, open-label trial, patients with DLBCL with an International Prognostic Index (IPI) score of ≥3 and CMR after R-CHOP received 1200 mg atezolizumab every 3 weeks for 18 cycles. The primary end point was disease-free survival (DFS) at 2 years, with the aim of improving it to 89% compared to historical 79%. Secondary end points included overall survival (OS) and safety (Common Terminol
