Arvinas Inc. announced new preclinical data supporting the combination of ARV-393, a PROTAC BCL6 degrader, with glofitamab, a CD20×CD3 bispecific antibody, as a potential chemotherapy-free treatment strategy for diffuse large B-cell lymphoma (DLBCL). The results were presented at the 2025 American Society of Hematology $(ASH)$ Annual Meeting and Exposition. In a humanized high-grade B-cell lymphoma cell line-derived xenograft model, the combination demonstrated significantly enhanced tumor growth inhibition and increased tumor regression compared to either agent alone. Arvinas plans to initiate a Phase 1 clinical trial cohort evaluating the ARV-393 and glofitamab combination in patients with DLBCL in 2026 and expects to share clinical data from the ongoing Phase 1 trial of ARV-393 in 2026.
