This open-label, multicenter, single-arm, phase 2 study assessed the safety and efficacy of blinatumomab consolidation therapy in adult patients with newly diagnosed, high-risk diffuse large B-cell lymphoma (DLBCL; International Prognostic Index 3–5 and/or double-/triple-hit or double MYC/BCL-2 expressors) who achieved complete response (CR), partial response (PR), or stable disease (SD) following run-in with 6 cycles of R-chemotherapy (NCT03023878). Of the 47 patients enrolled, 28 received blinatumomab. Five patients (17.9%) experienced grade 4 treatment-emergent adverse events of interest (neutropenia, n = 4; infection, n = 1). Two deaths reported at the end of the study were unrelated to treatment with blinatumomab (disease progression, n = 1; infection, n = 1). 3/4 patients with PR and 4/4 patients with SD after R-chemotherapy achieved CR following blinatumomab. Consolidation with blinatumomab in patients with newly diagnosed, high-risk DLBCL who did not progress under R-chemotherapy was better tolerated than in previous studies where blinatumomab was used for treatment of patients with lymphoma.
