Brief 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.

Detailed 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.

Recruitment details

One Arm 2 subject was screened and enrolled but consent was withdrawn prior to Day 0.

Pre-assignment details

All subjects in Arm 1 received 10mg daily of veledimex. A total of three subjects were assigned to Arm 2. One subject withdrew consent prior to any study procedures on Day 0 and received no treatment. A second subject was discontinued from the study due to a Serious Adverse Event (SAE) after the Ad-RTS-hIL-12 injection but prior to receiving veledimex. The third subject received veledimex at a dose of 5 mg/day, which was the body surface area (BSA)-adjusted dose.

To Measure the Veledimex in Blood and Brain Tumor by Using the LC-MS Method

Veledimex brain concentration. Veledimex plasma concentration was below the limit of quantitation for most patients. Given the limited number of subjects enrolled and early closure of the study, complete assessment of veledimex in blood and brain tumor could not be determined.

Time frame: From Day 0 through Day 15 of veledimex dosing

Population: Patients with available brain tumor results. Arm 2 patient result was below the level of quantitation (1.8 ng/mL). Arm 1 BLQ was 0.1 ng/mL. One patients was less than BLQ.~Arm 2 patient plasma concentrations were not reported due to bioanalytical non-reproducibility. NRR (Non-Reportable Results) is the actual result reported from the central lab which was due to assay reagent expiration.
