The US Food and Drug Administration (FDA) has granted Breakthrough Therapy designation to a novel CAR-T cell therapy known as WU-CART-007, developed by researchers at Washington University School of Medicine in St.Louis.This innovative cell-based immunotherapy targets aggressive forms of blood cancer, specifically T-cell acute lymphoblastic leukemia (T-ALL) and T-cell lymphoblastic lymphoma (T-LL).
