Summary

Despite the marginal improvements in survival of patients suffering from malignant glioma treated with gene therapy vectors, the clinical trials conducted so far using viral vectors, in particular adenoviral vectors, have proven that the use of adenoviral vectors is a safe therapeutic approach, even in large, multicenter, phase 3 clinical trials. Treatment of malignant glioma using gene transfer modalities typically consists of surgical debulking of the tumor mass followed by the administration of the viral vectors into the brain tissue surrounding the tumor cavity. This study will combine direct tumor cell killing (TK) and immune-mediated stimulatory (Flt3L) gene transfer approaches delivered by first generation adenoviral vectors.

BIOLOGICAL

Dose Escalation of Ad-hCMV-TK and Ad-hCMV-Flt3L

Two adenoviral vectors will be used, each to deliver one of the therapeutic genes. Both vectors are human serotype 5, replication-defective, first generation adenoviral vectors deleted in E1a and E3 viral encoding regions. Each vector will constitutively express their respective therapeutic transgene (i.e. HSV1-TK or Flt3L) under the control of the human cytomegalovirus promoter (hCMV). Valacyclovir treatment will begin 1-3 days after vector administration at a dose of 2 grams given orally 3X per day for 14 days. A second course of valacyclovir will be given beginning Week 10. Radiation and chemotherapy will be administered as per standard of care.
