BOSTON and GERMANTOWN, Md., Oct. 17, 2013 (GLOBE NEWSWIRE) -- ZIOPHARM Oncology, Inc. (Nasdaq:ZIOP), a biopharmaceutical company focused on the discovery and development of new cancer therapies, and Intrexon Corporation (NYSE:XON), a leader in synthetic biology, today announced scheduled poster presentations at the 2013 AACR-NCI-EORTC International Conference on Molecular Targets and Cancer Therapeutics, which is taking place October 19-23, 2013 in Boston. The conference is a joint meeting of the American Association for Cancer Research, the National Cancer Institute and the European Organisation for Research and Treatment of Cancer. The presentations will highlight studies conducted jointly between ZIOPHARM and Intrexon as part of an Exclusive Channel Collaboration to research, develop and commercialize novel in vivo DNA- and cell-based oncology therapeutics using different approaches, regulated by Intrexon's proprietary RheoSwitch Therapeutic System® (RTS®) platform.
The studies concern ZIOPHARM's lead therapeutic program, a monogenic system which enables the controlled delivery of therapeutic interleukin-12 (IL-12), in a glioma (brain tumor) model, as well as pipeline programs exploring: embedded cellular bioreactors capable of expressing three distinct immune effectors from a single RTS® gene switch; the use of mesenchymal stem cells for tumor targeted delivery of single or multiple regulated cancer immunotherapies; and the expression of high affinity single chain variable fragment-Fc (scFv-Fc) antibodies with target specificities based on trastuzumab (anti-Her2) and cetuximab (anti-EGFR) for gene therapy applications. ZIOPHARM expects to file multiple investigational new drug (IND) applications in 2014 and 2015 to begin exploring new targets in the clinic using technologies such as these.
The findings will be presented on Oct. 21 and 22, 2013. Specific times and locations are noted below.

About ZIOPHARM Oncology, Inc.:
ZIOPHARM Oncology is a Boston, Massachusetts-based biotechnology company employing novel gene expression and control technology to deliver DNA for the treatment of cancer. ZIOPHARM's technology platform employs Intrexon Corporation's RheoSwitch Therapeutic System® to turn on and off, and precisely modulate, gene expression at the cancer site in order to improve the therapeutic index. This technology is currently being evaluated in Phase 2 clinical studies of the immune system cytokine interleukin-12 for the treatment of breast cancer and advanced melanoma. Multiple new INDs for new targets using similar technology are expected in 2014 and 2015. ZIOPHARM is also developing novel small molecules as potential cancer therapeutics.
