FDA approves Tecartus for B-cell precursor acute lymphoblastic leukemia – Kite

Kite announced the FDA has granted approval for Tecartus (brexucabtagene autoleucel) for the treatment of adult patients (18 years and older) with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL). Following FDA Breakthrough Therapy Designation and a priority review, Tecartus is the first and only chimeric antigen receptor (CAR) T-cell therapy approved for adults (18 years and older) with ALL. There is a high unmet need, as half of this patient population will relapse, and median overall survival (OS) is only approximately eight months with current standard-of-care treatments.

The approval is based on results from ZUMA-3, a global, multicenter, single-arm, open-label study in which 65% of the evaluable patients (n=54) achieved complete remission (CR) or CR with incomplete hematological recovery (CRi) at a median actual follow-up of 12.3 months. The duration of CR was estimated to exceed 12 months for more than half the patients. Among efficacy-evaluable patients, median duration of remission (DOR) was 13.6 months. Among the patients treated with Tecartus at the target dose (n=78), Grade 3 or higher cytokine release syndrome (CRS) and neurologic events occurred in 26% and 35% of patients, respectively, and were generally well-managed.
