KITE’S CAR T-CELL THERAPY TECARTUS® (BREXUCABTAGENE AUTOLEUCEL) GRANTED EUROPEAN MARKETING AUTHORISATION FOR THE TREATMENT OF RELAPSED OR REFRACTORY ACUTE LYMPHOBLASTIC LEUKAEMIA (r/r ALL)

Kite Pharma



Stockley Park, UK – 7 September 2022
– Kite, a Gilead Company, today announced that the European Commission (EC) has approved its CAR T-cell therapy Tecartus® (brexucabtagene autoleucel) for the treatment of adult patients 26 years of age and above with relapsed or refractory (r/r) B-cell precursor acute lymphoblastic leukaemia (ALL).

“This approval makes brexucabtagene autoleucel the first and only CAR T-cell therapy indicated for this population of patients, addressing a significant unmet medical need,” said Christi Shaw, CEO, Kite. “This is also the fourth indication in Europe for which a Kite cell therapy is approved, clearly demonstrating the benefits they offer to patients, especially those with limited treatment options.”

ALL is an aggressive type of blood cancer; the most common form is B cell precursor ALL.[1] Globally, approximately 64,000 people are diagnosed with ALL each year.[2],[3] Half of adults living with ALL will relapse, and median overall survival (OS) with current standard-of-care treatments is approximately just eight months.[4],[5]

“Adults with relapsed or refractory ALL often undergo multiple treatments including chemotherapy, targeted therapy and stem cell transplant, creating a significant burden on a patient’s quality of life,” said Max S. Topp, MD, professor and head of Hematology, University Hospital of Wuerzburg, Germany. “Patients in Europe now have a meaningful advancement in treatment. Tecartus has demonstrated durable responses, suggesting the potential for long-term remission and a new approach to care.”

The approval is supported by data from the ZUMA-3 international multicentre, single-arm, open-label, registrational Phase 1/2 study of adult patients (≥18 years old) with relapsed or refractory ALL. This study demonstrated that 71% of the evaluable patients (n=55) achieved complete remission (CR) or CR with incomplete haematological recovery (CRi) with a median follow-up of 26.8 months.[6] In an extended data set of all pivotal dosed patients (n=78) the median overall survival for all patients was more than two years (25.4 months) and almost four years (47 months) for responders (patients who achieved CR or CRi).6,[7] Among efficacy-evaluable patients, median duration of remission (DOR) was 18.6 months.6

Among the patients treated with brexucabtagene autoleucel at the target dose (n=100) safety results were consistent with the known safety profile for brexucabtagene autoleucel. Grade 3 or higher cytokine release syndrome (CRS) and neurologic adverse reactions occurred in 25% and 32% of patients, respectively, and were generally well managed. [8],[9],[10]
