Ziopharm Oncology Receives Positive Opinion for Orphan Drug Designation from the European Medicines Agency for Ad-RTS-hIL-12 plus Veledimex for the Treatment of Glioma

900 Days ago

BOSTON, Aug. 08, 2019 (GLOBE NEWSWIRE) -- Ziopharm Oncology, Inc. (“Ziopharm” or “the Company”) (Nasdaq: ZIOP), today announced the European Medicines Agency (EMA) Committee for Orphan Medicinal Products (COMP) adopted a positive opinion recommending Ad-RTS-hIL-12 plus veledimex (Controlled IL-12) for designation as an orphan medicinal product for the treatment of glioma.

“Malignant glioma is an aggressive and life-threatening cancer with few treatment options,” said Laurence Cooper, M.D., Ph.D., Chief Executive Officer of Ziopharm. “We are pleased to receive a positive opinion from EMA COMP for orphan drug designation, as this represents another important milestone for our clinical program to treat recurrent glioblastoma multiforme.”

Orphan Medicinal Product designation by the European Commission provides certain regulatory and financial incentives for companies to develop and market therapies that treat a life-threatening or chronically debilitating condition affecting no more than five in 10,000 persons in the European Union and has the potential to be of significant benefit. In addition to a 10-year period of marketing exclusivity in the EU after product approval, this designation could allow for several incentives, including protocol assistance, access to the centralized authorization procedure and reduced regulatory fees.

About Ad-RTS-hIL-12 plus veledimex (Controlled IL-12 platform)
Ziopharm’s Controlled IL-12 platform is an investigational gene therapy designed to induce and control the production of human interleukin 12 (hIL-12) a master-regulator of the immune system. The Company has treated more than 100 patients, including more than 75 patients with recurrent glioblastoma multiforme (rGBM), with Ad-RTS-hIL-12 plus veledimex and administered more than 1,300 doses of veledimex across three types of solid tumors, building a significant safety profile, mechanistic dataset and evidence of anti-tumor effects.

At the 2018 annual meeting of the Society for Neuro-Oncology, Ziopharm presented data from its phase 1 dose-escalation trial showing that Controlled IL-12 had a positive survival benefit, with 15 patients who received 20mg veledimex reaching 12.7 months median overall survival (mOS) at a mean follow up of 13.1 months. A subset of these patients (n=6) who received low-dose steroids (20mg or less of dexamethasone cumulatively over 15 days while receiving veledimex) had mOS of 17.8 months compared to 6.4 months mOS for patients (n=9) who received more than 20mg of dexamethasone during the same period. The survival data from patients who received the preferred dosing regimen of Controlled IL-12 with 20mg veledimex and low-dose steroids compare favorably to a benchmark mOS of 6 to 9 months for patients with rGBM that serves as historical control.

The Company announced earlier this year the completion of the enrollment in an “Expansion Substudy” (Clinicaltrials.gov NCT03679754) that enlarged the phase 1 trial by an additional 36 patients with Ad-RTS-hIL-12 plus 20mg/day veledimex for up to 14 days. In that cohort, 75% of patients (27/36) received low-dose steroids.

FDA Fast Track and Orphan Designation
In April 2019, Ziopharm announced that the U.S. Food and Drug Administration (FDA) had granted Fast Track designation for the Company’s Controlled IL-12 program for the treatment of rGBM in adults. Ziopharm also previously received Orphan Drug designation from the FDA’s Office of Orphan Products for the treatment of patients with malignant glioma.
