Brexucabtagene autoleucel (Tecartus – Kite) has been approved by the FDA for treatment of adults with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL). It was previously approved for treatment of relapsed or refractory mantle cell lymphoma. Tecartus is an individualized cellular product prepared from the patients own T cells, which are genetically modified to express chimeric antigen receptors (CAR) and then infused back into the patient. The CAR T-cell immunotherapy tisagenlecleucel (Kymriah) was approved in 2017 for treatment of relapsed or refractory B-cell precursor ALL in patients ≤25 years old.
