Easy as ABC: Managing Toxicities of Antibody-Drug Conjugates, Bispecific Antibodies, and CAR T-Cell Therapies

Antibody-drug conjugates (ADCs), bispecific antibodies that engage T cells (BsAbs), and chimeric antigen receptor (CAR) T cells are widely used standard-of-care therapies that have revolutionized the treatment of lymphoid and plasma cell malignancies. With recent regulatory approvals, these therapies are poised to also revolutionize the treatment of common solid tumors and become a part of the everyday lexicon, the ABCs, of the practicing oncologist. Drawing from experience in hematology, we review the early, late, and rare toxicities of ADCs, BsAbs, and CAR T cells and provide general principles for their management.
