SANTA MONICA, Calif., June 2, 2015 (GLOBE NEWSWIRE) -- Kite Pharma, Inc., (Nasdaq:KITE), today announced clinical biomarker data from patients with relapsed/refractory B cell malignancies treated with anti-CD19 chimeric antigen receptor (CAR) T-cell therapy in a poster presentation during the 51st Annual Meeting of the American Society of Clinical Oncology (ASCO), which is taking place in Chicago. In an ongoing Phase 1 clinical trial at the National Cancer Institute (NCI), being conducted under a Cooperative Research and Development Agreement (CRADA) between Kite Pharma and the NCI, patients with diverse B cell tumors are conditioned with cyclophosphamide and fludarabine, then dosed with their own T cells genetically modified to express a CAR designed to target the antigen CD19, a protein expressed on the cell surface of B-cell lymphomas and leukemias. As reported at last year's ASCO meeting, 76% of evaluable patients (N=29) achieved an overall response rate in this study. In this updated biomarker analysis, conditioning chemotherapy was associated with a significant rise in homeostatic cytokines and chemokines, which could favor expansion, activation, and trafficking of CAR T cells. In addition, the recovery of B cells was seen in 7 of 12 patients with ongoing response duration greater than 12 months.
David Chang, M.D., Ph.D., Kite Pharma's Executive Vice President, Research and Development, and Chief Medical Officer, and an author on the poster, commented, "The results being reported at ASCO provide additional key insights and further deepen our understanding of CAR T-cell therapy. We will continue to investigate biomarkers that may predict the clinical outcome in our ongoing KTE-C19 (anti-CD19 CAR T) clinical program which initiated patient dosing last month."
The ASCO meeting poster, titled "Biomarker Analysis of Patients Treated with Anti-CD19 Chimeric Antigen Receptor (CAR) T Cells" (Abstract # 3028), is available on the Kite Pharma website at http://www.kitepharma.com/c/news/publications.php. Further information on the NCI clinical trial protocols can be found at ClinicalTrials.gov, using Identifier NCT: 00924326.
