On Oct. 1, 2021, Kite, a Gilead Company, announced the U.S. Food and Drug Administration (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. Patients can access Tecartus through 109 authorized treatment centers across the U.S.

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.

Adults with relapsed or refractory ALL often undergo multiple treatments including chemotherapy, targeted therapy and stem cell transplant. CAR T-cell therapy works differently, by harnessing a patient’s own immune system to fight cancer. With CAR T, the patient’s blood is drawn and the T cells are separated. Then the T cells are genetically engineered with a specific receptor that enables them to identify and attack cancer cells, and put back into the patient’s body.

Tecartus was also currently under review in the European Union and United Kingdom for the treatment of adult patients with relapsed or refractory B-cell precursor ALL.

The Tecartus U.S. Prescribing Information has a BOXED WARNING for the risks of CRS and neurologic toxicities, and Tecartus is approved with a Risk Evaluation and Mitigation Strategy (REMS) due to these risks; see below for Important Safety Information.
