Houston, Texas, UNITED STATES

BOSTON, May 7, 2015 (GLOBE NEWSWIRE) -- ZIOPHARM Oncology, Inc. (Nasdaq:ZIOP) today announced the appointment of Laurence J. N. Cooper, M.D., Ph.D., to the role of Chief Executive Officer, effective immediately. Dr. Cooper brings extensive experience in pioneering the development of adoptive cellular therapies in the field of oncology and translating immunology into clinical practice. He succeeds Jonathan Lewis, M.D., Ph.D., who will remain a member of the Company's Board of Directors.

"The addition of Dr. Cooper further enhances the progress of ZIOPHARM in building a world-class suite of programs and technologies for advancing the leading, regulated immuno-oncology gene and adoptive CAR T, TCR and NK cell therapies," said Sir Murray Brennan, M.D., Lead Director of ZIOPHARM. "We thank Jon Lewis for his lifelong commitment to science and clinical care and his contributions during his years of service as CEO of the Company. At this stage in ZIOPHARM's evolution, Dr. Cooper's appointment is a tremendous gain for the Company, given his expertise in immunotherapy and central role in the development and clinical translation of MD Anderson Cancer Center's adoptive cell therapy programs."

"By harnessing and enhancing the power of the immune system, adoptive cell therapy holds the promise of curing many cancers," said Dr. Cooper. "Central to achieving this objective is our ability to solve the puzzle of linking together different proteins, receptors, cell types, gene switches and associated technologies to target a broad spectrum of malignancies. Together, I believe ZIOPHARM, Intrexon, MD Anderson and Merck Serono have the technologies, programs and know-how to lead this effort, and I look forward to driving our success in this new role."

Dr. Cooper added: "ZIOPHARM has unique potential in the human application of immune cells. The synthetic biology of Intrexon is being combined with ZIOPHARM's ability to deliver potent therapeutics. Together with our partners, we have a unique opportunity to bring new immune-based therapies into the war on cancer."

Dr. Cooper joined The University of Texas MD Anderson Cancer Center in 2006, where his appointments include tenured professor, Pediatrics and Immunology; Section Chief, Cell Therapy, Children's Cancer Hospital; and Associate Director, Center for Cancer Immunology Research. He obtained his M.D. and Ph.D. degrees at Case Western Reserve University in Cleveland and then training in Pediatric Oncology and Bone Marrow Transplantation at the Fred Hutchinson Cancer Research Center in Seattle.  Dr. Cooper has received numerous awards and honors and in addition to numerous other professional appointments, he has authored more than 140 journal articles, book chapters, and abstracts.
