Introduction

CD3 bispecific antibody drugs are engineered therapeutic proteins that simultaneously bind the CD3 receptor on T cells and a selected tumor-associated antigen, facilitating targeted T-cell activation and tumor cell lysis. These constructs harness the patient’s own immune system for cytotoxic activity without requiring ex vivo manipulation, differentiating them from adoptive cell therapies.

In North America, CD3 bispecifics are being explored extensively for treatment of hematologic malignancies such as acute lymphoblastic leukemia (ALL), non-Hodgkin lymphoma (NHL), chronic lymphocytic leukemia (CLL), and multiple myeloma, with increasing interest in solid tumor targets. Molecular engineering strategies — including half-life extension, multispecific engagement, and safety switch incorporation — are improving therapeutic indices and widening clinical applicability.
