Conventional salvage chemotherapy has limited efficacy, and CAR-T cell therapy may be limited by manufacturing time, accessibility, and patient condition. Therefore, an immediately available, chemotherapy-free treatment strategy that may reduce the cumulative toxicity of conventional cytotoxic chemotherapy is needed.\n\nPolatuzumab vedotin is a CD79b-targeted antibody-drug conjugate that delivers a cytotoxic agent to malignant B cells, and glofitamab is a CD20×CD3 bispecific antibody that activates T cells and induces immune-mediated antitumor activity. The combination of these two agents may provide complementary antitumor effects through direct tumor cell killing and T-cell-mediated immune response.\n\nThis single-arm, open-label, phase 2 study will evaluate the efficacy and safety of polatuzumab vedotin in combination with glofitamab in patients with DLBCL who are primary refractory to or relapse within 12 months after first-line R-CHOP therapy.
