ZIOPHARM Announces Four Presentations at the 2016 ASH Annual Meeting

BOSTON, Nov. 03, 2016 (GLOBE NEWSWIRE) -- ZIOPHARM Oncology, Inc. (Nasdaq:ZIOP), a biopharmaceutical company focused on new cancer immunotherapies, today announced that four abstracts highlighting data from the Company’s adoptive cell-based therapeutic programs have been accepted for presentation at the 58th American Society of Hematology (ASH) Annual Meeting and Exposition. The meeting will be held December 3-6, 2016 in San Diego.

The research, conducted at The University of Texas MD Anderson Cancer Center and Intrexon Corporation (NYSE:XON) demonstrates, among other results, that T cells can be quickly produced with the Sleeping Beauty system and that this non-viral approach to gene therapy can be harnessed to generate chimeric antigen receptor (CAR) and T-cell receptor (TCR) expressing effector cells.

"This suite of nonclinical data underscores the technology underlying our adoptive cell-based programs, including the potential for the Sleeping Beauty platform to improve the manufacture of genetically modified T cells and our ability to redirect T-cell specificity to blood cancers and solid tumors using CARs and TCRs," said Laurence Cooper, M.D., Ph.D., Chief Executive Officer of ZIOPHARM. "This research advances our plans to rapidly and cost-effectively deliver engineered T cells, and we look forward to seeing it translate into clinical programs."
