This presentation contains certain forward-looking information about ZIOPHARM Oncology, Inc. that is intended to be covered by the safe harbor for “forward-looking statements” provided by the Private Securities Litigation Reform Act of 1995, as amended. Forward-looking statements are statements that are not historical facts, and in some cases can be identified by terms such as “may,” “will,” “could,” “expects,” “plans,” “anticipates,” and “believes.” These statements include, but are not limited to, statements regarding the progress, timing and results of preclinical and clinical trials involving the Company’s drug candidates, and the progress of the Company’s research and development programs. All of such statements are subject to certain risks and uncertainties, many of which are difficult to predict and generally beyond the control of the Company, that could cause actual results to differ materially from those expressed in, or implied by, the forward-looking statements. These risks and uncertainties include, but are not limited to: whether chimeric antigen receptor T cell (CAR T) approaches, Ad-RTS-IL-12, TCR and NK cell-based therapies, or any of our other therapeutic candidates will advance further in the pre-clinical or clinical trials process and whether and when, if at all, they will receive final approval from the U.S. Food and Drug Administration or equivalent foreign regulatory agencies and for which indications; whether chimeric antigen receptor T cell (CAR T) approaches, Ad-RTS-IL-12, TCR and NK cell-based therapies, and our other therapeutic products will be successfully marketed if approved; the strength and enforceability of our intellectual property rights; competition from other pharmaceutical and biotechnology companies; and the other risk factors contained in our periodic and interim SEC reports filed from time to time with the Securities and Exchange Commission, including but not limited to, our Annual Report on Form 10-K for the fiscal year ended December 31, 2015. Readers are cautioned not to place undue reliance on these forward-looking statements that speak only as of the date hereof, and we do not undertake any obligation to revise and disseminate forward-looking statements to reflect events or circumstances after the date hereof, or to reflect the occurrence of or non-occurrence of any events.

Natural Killer Cells: Beyond CAR+ T cells
Natural killer (NK) cells
– Target tumors, e.g., with loss or mismatch of HLA
– Killing is independent of a specific (known) target antigen
– Cytokines, e.g., IL-12 are “fuel” for NK cells
– Build on promising proof-of-principle trials ongoing at MDACC infusing autologous and allogeneic NK cells manufactured using feeder cells

TCR: Targeting private somatic mutations (neo-antigens)
PERSPECTIVE nature medicine Prospects for gene-engineered T cell immunotherapy for solid cancers
Nat Med. 2016 Jan 6;22(1):26-36
Science. 2015 Apr 3;348(6230):62-8
Science. 2015 Apr 3;348(6230):69-74
Direct binding
CAR+ T cell
10% of proteins are on cell surface
Indirect binding
TCR+ T cell
90% of proteins are within a cell
“Clinical evidence supports the hypothesis that immunogenic products of somatic mutations unique to each patient’s cancer—so-called neoantigens—are the relevant targets for successful immunotherapies”
“Success for cell-based immunotherapies may come from the arduous task of targeting the unique set of mutations that cause each patient’s cancer”
“Presently, use of the Sleeping Beauty (SB) transposon / transposase system has advanced farthest in clinical development”
