Development of ALL-Hematotox (ALL-HT): Predicting post CAR T-cell hematotoxicity in B-cell acute lymphoblastic leukemia

Immune effector cell-associated hematotoxicity (ICAHT) is a major B-cell targeted chimeric antigen receptor (CAR) T-cell related toxicity. While ICAHT incidence and severity is documented in large B-cell lymphoma (LBCL), mantle cell lymphoma (MCL), and multiple myeloma (MM), ICAHT has not been described in B-cell acute lymphoblastic leukemia (B-ALL). Similarly, the CAR-HEMATOTOX (CAR-HT) model, designed to predict severe prolonged neutropenia (>14 days of ANC <500/µl), has been validated …
