Kai Rejeski, MD, Memorial Sloan Kettering Cancer Center, New York City, NY, shares insights into CAR-Tography, a large international study that mapped CAR-T toxicities across B-cell malignancies, including cytokine release syndrome (CRS), immune effector cell-associated neurotoxicity syndrome (ICANS), hematotoxicity, and infections. By analyzing data from approximately 900 patients and 32,000 unique patient days, they derived a cumulative toxicity index (CTI) to describe early CAR T-cell toxicity. Three clusters were identified: high-tox, mid-tox, and low-tox, which were prognostically relevant and biologically distinct. This study provides a holistic view of CAR-T toxicity and has implications for product selection and patient stratification. This interview took place at the 66th ASH Annual Meeting and Exposition, held in San Diego, CA.
