The rapid emergence of CD20-targeting T-cell engagers in follicular lymphoma and large B-cell lymphoma has further expanded the treatment options for patients with relapsed or refractory disease. Herein, we review and discuss the standard-of-care products and indications for mosunetuzumab, epcoritamab, and glofitamab. We provide a detailed overview of the registrational clinical trials, as well as a review of ongoing trials and likely future indications. We also address how we incorporate T-cell engagers in our current treatment paradigm, with particular emphasis on their use with and as alternatives to chimeric antigen receptor T-cell therapy. We further discuss our management of immune effector cell-related toxicities.
