On July 7, 2016 Kite Pharma, Inc. (Nasdaq: KITE), a clinical-stage biopharmaceutical company focused on developing engineered autologous cell therapy (eACT) products for the treatment of cancer, reported that it has completed enrollment of 72 patients in DLBCL cohort in the Phase 2 portion of ZUMA-1 (Press release, Kite Pharma, JUL 7, 2016, View Source [SID:1234513763]). KTE-C19 is an investigational therapy in which a patient’s T-cells are genetically modified to express a chimeric antigen receptor (CAR) that is designed to target the antigen CD19, a protein expressed on the cell surface of B-cell lymphomas and leukemias.

The DLBCL cohort of ZUMA-1 enrolled patients whose disease is chemorefractory (no response to last line of therapy or has relapsed within 12 month of autologous stem cell therapy). Patients received a lymphodepletion regimen that consisted of "low-dose" chemotherapy regimen of cyclophosphamide (500 mg/m2) and fludarabine (30 mg/m2) daily for 3 days prior to infusion of the target KTE-C19 dose of 2 x 106 cells/kg.

"We are excited to complete enrollment in our first multi-center KTE-C19 study, an important milestone toward bringing this potential breakthrough therapy to patients with an urgent need for better treatment," said David Chang, M.D., Ph.D., Kite’s Executive Vice President, Research and Development, and Chief Medical Officer. "We are grateful to the patients and investigators who participated in our study. We look forward to announcing top-line data from the first 50 DLBCL patients in the ZUMA-1 study, and, subject to these results, plan on submitting our Biologics License Application (BLA) with the U.S. Food and Drug Administration by the end of 2016."
