Introduction

Bispecific T-Cell Engager (BiTE) therapies are a class of engineered biologics that connect cytotoxic T lymphocytes with malignant cells by dual binding to CD3 on T cells and a tumor-associated antigen, promoting targeted immune-mediated tumor cell destruction. Unlike traditional monoclonal antibodies, BiTEs facilitate direct immune cell engagement without requiring major histocompatibility complex presentation.

This mechanism enables potent antitumor activity, even in therapy-resistant settings. In North America, BiTE therapies are being investigated across a range of hematologic malignancies such as acute lymphoblastic leukemia (ALL), multiple myeloma, and emerging solid tumor targets. Engineering advancements such as half-life extension platforms, optimized linkers, and safety switches are improving clinical viability and therapeutic indices.
