Kite Pharma Announces Publication in Science of Cancer Immunotherapy Articles Authored by Lead Collaborators at the National Cancer Institute and the Netherlands Cancer Institute

SANTA MONICA, Calif., April 6, 2015 (GLOBE NEWSWIRE) -- Kite Pharma, Inc. (Kite) (Nasdaq:KITE), a clinical-stage biopharmaceutical company focused on developing engineered autologous T cell therapy (eACT™) products for the treatment of cancer, today announced articles being published in the current issue of Science, one article by the Company's Cooperative Research and Development Agreement (CRADA) collaborators at the National Cancer Institute (NCI) and the second article by the Netherlands Cancer Institute (NKI). The first article, "Adoptive Cell Transfer as personalized immunotherapy for human cancer," was authored by Steven A. Rosenberg, M.D., Ph.D., Chief of Surgery at the NCI, and his colleague Nicholas P. Restifo, M.D., Senior Investigator at NCI's Surgery Branch. The second article, "Neoantigens in cancer immunotherapy," was written by Professor Dr. Ton N. M. Schumacher, Ph.D., Deputy Director of NKI, and Robert D. Schreiber, Ph.D., Director, Center for Human Immunology and Immunotherapy Programs, at Washington University School of Medicine. Professor Schumacher also serves as Chief Scientific Officer of Kite Pharma EU.

In their article, Drs. Rosenberg and Restifo reviewed the development of adoptive cell therapy, including the advent of genetically modified T cells and their promising results in patients with multiple tumor types. Last month, Kite announced an expansion of its CRADA with the Surgery Branch at the NCI, led by Dr. Rosenberg. The amendment encompasses emerging areas of research in the immune response to tumor neoantigens, in addition to new T cell receptor (TCR) and chimeric antigen receptor (CAR) product candidates targeting solid tumors.

Also, in March, Kite acquired T-Cell Factory B.V. (TCF™), a privately held Dutch company founded by preeminent scientists, including Professor Schumacher and Professor Dr. Dirk H. Busch, M.D., of the Technische Universität München (TUM). The acquisition of TCF greatly expands Kite's TCR product platform to discover and develop TCR-based product candidates for the treatment of solid tumors, complementing Kite's CAR pipeline. TCF was renamed Kite Pharma EU and provides a base for Kite to build its global presence.

In their review article, Professor Schumacher and Dr. Schreiber described breakthrough patient-specific neoantigen research, including the targeting of multiple neoantigens to augment patient responses. According to the authors, "Because of the tumor-restricted expression of the antigens that are being targeted, these personalized cancer immunotherapies offer the promise of high specificity and safety. Conceivably, the boosting of neoantigen-specific T cell reactivity that can be achieved with such personalized immunotherapies will further increase the spectrum of human malignancies that respond to cancer immunotherapy."

"Our alliances, including with CRADA collaborator NCI and now with NKI, are essential to building and growing our pipeline of promising clinical and preclinical programs," said Arie Belldegrun, M.D., FACS, Chairman, President and Chief Executive Officer.  "Based on our progress, there are six ongoing trials under our CRADA with the NCI and we anticipate initiating four pivotal trials of our anti-CD19 CAR product candidate, KTE-C19, in 2015. This momentum is built on strong foundations and relationships."
