Mohammad Maher Abdul-Hay, MD, an assistant professor in the Department of Medicine; director of the Clinical Leukemia Program in NYU Langone Health’s Perlmutter Cancer Center; and associate director for research in the Bellevue Cancer Center, discusses the use of bispecific T-cell engagers (BiTEs) in acute lymphoblastic leukemia (ALL).

BiTEs are a novel drug class that were first investigated in ALL, says Abdul-Hay. In ALL and other malignancies, the immune system cannot recognize the leukemic cells, adds Abdul-Hay. However, the drug attaches to the patient's T cells and uses the immune system to attack B cells and kill cancer cells.

Notably, BiTEs are less toxic than other therapies; however, because they hyperactivate the immune system via T-cell activation, they have a different safety profile than chemotherapy. One of the adverse events associated with these therapies is cytokine release syndrome (CRS), which occurs when the T cells and memory cells release inflammatory cytokines. Symptoms include fever and low blood pressure, depending on the grade of the CRS, says Abdul-Hay. Patients who can get past the CRS tend to tolerate the treatment fairly well, concludes Abdul-Hay.
