A Study of Ad-RTS-hIL-12 + Veledimex in Pediatric Subjects With Brain Tumors Including DIPG

Diffuse Intrinsic Pontine Glioma Clinical Trial

Official title: A Phase I/II Study of Ad-RTS-hIL-12, an Inducible Adenoviral Vector Engineered to Express hIL-12 in the Presence of the Activator Ligand Veledimex in Pediatric Brain Tumor Subjects

Status Terminated

Clinical Trial Summary

This research study involves an investigational product: Ad-RTS-hIL-12 given with veledimex for production of human IL-12. IL-12 is a protein that can improve the body's natural response to disease by enhancing the ability of the immune system to kill tumor cells and may interfere with blood flow to the tumor.

The main purpose of this study is to evaluate the safety and tolerability of a single tumor injection of Ad-RTS-hIL-12 given with oral veledimex in the pediatric population.

Clinical Trial Description

Eligible patients will be stratified to one of two arms, according to clinical indication for tumor resection. Pediatric patients who are scheduled for craniotomy and tumor resection will receive one dose of veledimex before the resection procedure. Ad-RTS-hIL-12 will be administered by free-hand injection. Patients will continue on oral veledimex for 14 days. This arm has been completed and is currently closed to enrollment.

Pediatric patients with diffuse intrinsic pontine glioma (DIPG) will receive Ad-RTS-hIL-12 by stereotactic injection and then will continue on oral veledimex for 14 days.

The study is divided into three periods: the screening period, the treatment period and the follow-up period. ;
