Bispecific T-cell recruiting antibodies are emerging as a potent immunotherapeutic class in the treatment of B-cell malignancies and act by simultaneously targeting antigens on T-cells and malignant cells to effect tumor cell death. Glofitamab is a novel full-length IgG-like CD20-CD3 bispecific with a unique 2:1 configuration that provides an extended half-life and superior CD20 binding. Phase 1 monotherapy and combination data demonstrate clear activity in heavily treated aggressive and indolent B-cell lymphoma, including >50% complete responses at the recommended phase 2 dose. In this review, we provide an overview of the structure, mechanism of action and pharmacokinetics of glofitamab. Available efficacy and safety data from ongoing clinical trials are also presented. Glofitamab appears to be a welcome addition to the treatment possibilities for patients with B-cell lymphomas who otherwise have limited therapeutic options. The current data are sufficient to evaluate its role in combination and in earlier lines of therapy.
