-- Approval Marks Kite’s Fourth Indication in Europe for its Two Cell Therapies and First in Leukemia --

SANTA MONICA, CA, USA I September 06, 2022 I Kite, a Gilead Company (Nasdaq: GILD), 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 leukemia (ALL).
“This approval makes Tecartus 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. Globally, approximately 64,000 people are diagnosed with ALL each year. Half of adults living with ALL will relapse, and median overall survival (OS) with current standard-of-care treatments is approximately just eight months.
“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 multicenter, 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 hematological recovery (CRi) with a median follow-up of 26.8 months. 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). Among efficacy-evaluable patients, median duration of remission (DOR) was 18.6 months.
Among the patients treated with Tecartus at the target dose (n=100) safety results were consistent with the known safety profile for Tecartus. 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.
ZUMA-3 is an ongoing international multicenter (US, Canada, Europe), single arm, open label, registrational Phase 1/2 study of Tecartus in adult patients (≥18 years old) with ALL whose disease is refractory to or has relapsed following standard systemic therapy or hematopoietic stem cell transplantation. The primary endpoint is the rate of overall complete remission or complete remission with incomplete hematological recovery by central assessment. Duration of remission and relapse-free survival, overall survival, minimal residual disease (MRD) negativity rate, and allo-SCT rate were assessed as secondary endpoints.
About Acute Lymphoblastic Leukemia
ALL is an aggressive type of blood cancer that develops when abnormal white blood cells accumulate in the bone marrow until there isn’t any room left for blood cells to form. In some cases, these abnormal cells invade healthy organs and can also involve the lymph nodes, spleen, liver, central nervous system and other organs.
Please see full FDA Prescribing Information, including BOXED WARNING and Medication Guide.
Tecartus is a CD19-directed genetically modified autologous T cell immunotherapy indicated for the treatment of:
- Adult patients with relapsed or refractory mantle cell lymphoma (MCL).
This indication is approved under accelerated approval based on overall response rate and durability of response. Continued approval for this indication may be contingent upon verification and description of clinical benefit in a confirmatory trial.
- Adult patients with relapsed or refractory B-cell precursor acute lymphoblastic leukemia (ALL).
