About Ad-RTS-hIL-12 plus Veledimex
ZIOPHARM is advancing Ad-RTS-hIL-12 plus veledimex as a gene therapy for glioblastoma. Ad-RTS-hIL-12 is an adenoviral vector administered via a single injection into the tumor and engineered to express hIL-12, a powerful cytokine that has demonstrated the potential to stimulate a targeted, anti-tumor immune response. The expression of hIL-12 is controlled and modulated with the RheoSwitch Therapeutic System® (RTS®) by the small molecule veledimex, an activator ligand which has been shown to cross the blood brain barrier. ZIOPHARM anticipates initiation of a pivotal trial for Ad-RTS-hIL-12 plus veledimex for the treatment of rGBM by the end of 2017. The Company also has initiated a Phase 1 study to evaluate the stereotactic administration of Ad-RTS-hIL-12 plus veledimex in adult patients with rGBM, and plans to initiate enrollment of adult patients with rGBM who will receive a single dose of Ad-RTS-hIL-12 plus veledimex in combination with a checkpoint inhibitor targeting programmed cell death protein 1 (PD-1) by the end of the year.
