The US Food and Drug Administration (FDA) has granted Breakthrough Therapy designation to a groundbreaking CAR-T cell therapy, WU-CART-007 (soficabtagene geleucel), developed by researchers at Washington University School of Medicine in St.Louis.This designation is reserved for treatments that demonstrate substantial improvement over existing options for serious or life-threatening conditions, expediting their development and regulatory review.
