ZIOPHARM Issues Statement Regarding Misleading Blog

NEW YORK, Oct. 19, 2012 (GLOBE NEWSWIRE) -- ZIOPHARM Oncology, Inc. (Nasdaq:ZIOP) today issued the following statement regarding a blog entry posted by Richard Pearson, Contributor, on Forbes.com:

"The statements made in Mr. Pearson's blog entry are misleading and wrong and, given his disclosed investment position, we call into question the entire credibility of this piece. The Form 483 was issued directly to the independent investigator, not to ZIOPHARM, and had nothing to do with any outcome measures of the Phase 2 PICASSO study. All regulatory matters raised in Mr. Pearson's blog entry were resolved by the investigator in full in 2010, and had no impact on the Company's transition from Phase 2 to Phase 3. Further, the Company has no issues with drug stability. We stand by the clinical data generated at this investigator's site. Consistent with best practices, all data from ZIOPHARM's Phase 2 PICASSO study at this site were reviewed by an independent, former FDA good clinical practice (GCP) auditor, and the auditor concluded that the study site's violations had no impact on the PICASSO study or the quality of data."
