Brief summary
The primary goal of this Phase I study is to determine the maximum tolerated dose of oncolytic adenovirus mediated double suicide-gene therapy in combination with fractionated stereotactic radiosurgery in patients with recurrent high-grade astrocytoma undergoing resection.
Detailed description
Detailed study description: Patients with recurrent glioblastoma (GBM) or progressive high grade astrocytoma who are scheduled to undergo repeat surgery are eligible. After the removal of as much tumor tissue as possible, a modified oncolytic adenovirus is injected into the wall of the resection cavity and any residual tumor tissue. The goal of this study is to determine the maximum tolerated dose (MTD) of the injected adenovirus. This treatment is combined with a combination of oral 5-fluorocytosine (5-FC) and valganciclovir (vGCV) prodrug therapy. Following the surgery, patients will be treated with fractionated radiosurgery (fSRS). Patients will be monitored for 30 days before they start on next line anti-cancer therapy.

Inclusion criteria
1. Subjects with radiologic evidence of intracranial recurrence or progression of a previously diagnosed high-grade astrocytoma. To be eligible for this trial, the subjects must have: * Histologically documented glioblastomas or anaplastic astrocytoma prior to the debulking surgery that is suspicious to have progressed on imaging. An interval of at least 3 months must have elapsed since the completion of the most recent course of radiation while at least 4 weeks must have elapsed since the completion of a non-nitrosourea containing chemotherapy regimen and at least 6 weeks since the completion of a nitrosourea containing chemotherapy regimen. * Patients must be ≥ 18 years of age, able to provide informed consent and express a willingness to meet all the expected requirements of the protocol for the duration of the study. * Must have recovered from toxicity (grade 2 or less) of prior therapy. * Eligible for partial or total resection of the recurrent tumor * No anticipated physical connection between post-resection tumor cavity and cerebral ventricle * Karnofsky performance status (KPS) ≥ 60 at time of surgery * No prior treatment of the tumor with gene or virus therapy, immunotherapy, brachytherapy, or implants of polymers containing chemotherapeutic agents (e.g. Gliadel Wafer) * No immunosuppressive or immune disorder * Baseline organ function testing intact * Patients who are candidates for surgical debulking (re-resection) following recurrence of diseases based on multidisciplinary evaluation by neurosurgeons, radiation oncologists, neuro-radiologists, and neuro-oncologists. 2. Subjects must have adequate baseline organ function, as assessed by the following laboratory values, within 30 days before initiating the study therapy: * Adequate renal function with creatinine clearance ≥ 50 mL/min/m2 * Platelet count ≥ 100,000/μL * Absolute neutrophil count ≥ 1,000/μL * Hemoglobin \> 10.0 g/dL * Bilirubin \< 1.5 mg/dL; SGOT and SGPT \< 2.5 times upper limit of normal (ULN). 3. Women of child-bearing potential will be required to practice birth control for the duration of the treatment and for at least 90 days after surgery with intratumor virus inoculation. Men must use barrier protection for the duration of treatment and for at least 90 days after surgery with intratumor virus inoculation treatment.
Exclusion criteria
* Acute infection. Acute infection is defined by any viral, bacterial, or fungal infection that has required active treatment and caused oral temperature \>38.5oC and/or clinically significant leukocytosis * Serum antibodies to human immunodeficiency virus (HIV) * Previous history of liver disease including autoimmune or viral hepatitis * Positive serologic test for Hepatitis B or C at baseline * Immunosuppressive therapy except for corticosteroid use * Serious medical or psychiatric illness or concomitant medication, which, in the judgment of the investigator, might interfere with the subject's ability to respond to or tolerate the treatment or complete the trial * Impaired immunity or susceptibility to serious viral infections * Pregnant or lactating females * Allergy to any product used on the protocol * Patient is not able to undergo a brain MRI. * Patients who are not eligible for debulking surgery or resection of recurrent disease will be considered ineligible.
