Carmustine Implants and O(6)-Benzylguanine in Treating Children With Recurrent Malignant Glioma Clinical Trials Information presented on Clinical Trials Search is not designed to be a substitute for certified medical advice, trips or professional assistance with a real medical doctor. We aren't docs. Always confer with your doctor about Carmustine Implants and O(6)-Benzylguanine in Treating Children With Recurrent Malignant Glioma conditions. Clinical Trials Search.org is a website committed to listing clinical research studies in human subjects. Carmustine Implants and O(6)-Benzylguanine in Treating Children With Recurrent Malignant Glioma Clinical research trials and Carmustine Implants and O(6)-Benzylguanine in Treating Children With Recurrent Malignant Glioma health trials happen in many of cities across the US. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally measure the effectualness of new does drugs. The intention of the studies / projects is to figure out particular human healthcare questions. Clinical trials are a popular manner for doctors, government agencies, and private sector corporations to detect cures for all forms of circumstances, like Carmustine Implants and O(6)-Benzylguanine in Treating Children With Recurrent Malignant Glioma. Carmustine Implants and O(6)-Benzylguanine in Treating Children With Recurrent Malignant Glioma Clinical Trials and other clinical trials allow for volunteers to undergo medical treatment options before they are available to the general public. Most times the subjects get treatment for free of charge, and occasionally they are paid for their time. Occasionally there is a cost for a Carmustine Implants and O(6)-Benzylguanine in Treating Children With Recurrent Malignant Glioma clinical trial. Subjects frequently get the best healthcare possible for their Carmustine Implants and O(6)-Benzylguanine in Treating Children With Recurrent Malignant Glioma condition. Hazards are a reality, however, and could include more or frequent mD visits, health risks (possibly life-jeopardizing), and/or the treatment being ineffectual. Trials are federally regulated with exacting guidelines to protect clinical trials patients.

Carmustine Implants and O(6)-Benzylguanine in Treating Children With Recurrent Malignant Glioma
For Condition: recurrent childhood cerebral astrocytoma
Status: Recruiting
Sponsor(s): Pediatric Brain Tumor Consortium , National Cancer Institute (NCI)
Synopsis: RATIONALE: Drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. Chemotherapy placed into the surrounding tissue after surgery to remove the tumor may kill any remaining tumor cells. O(6)-benzylguanine may increase the effectiveness of carmustine by making tumor cells more sensitive to the drug. PURPOSE: Phase I trial to study the effectiveness of combining O(6)-benzylguanine with carmustine implants in treating children who have recurrentmalignantglioma.
Details: OBJECTIVES: - Determine the dose of O(6)-benzylguanine that reliably inhibits alkylguanine-DNA alkyltransferase activity in pediatric patients with recurrent malignant glioma. - Determine the toxic effects of O(6)-benzylguanine and polifeprosan 20 with carmustine implant (Gliadel) in these patients. - Determine antitumor response in patients treated with this regimen. OUTLINE: This is a multicenter, dose-escalation study of O(6)-benzylguanine. Patients receive O(6)-benzylguanine (O6-BG) IV over 1 hour immediately followed by O6-BG IV continuously for 9 days. Two days after initiation of continuous infusion of O6-BG, patients undergo maximal tumor debulking. At the time of surgery, patients receive up to 8 polifeprosan 20 wafers with carmustine (Gliadel) implanted into the resection cavity. Cohorts of up to 14 patients receive escalating doses of continuous infusion O6-BG until the optimally biologically effective dose (BED) is determined. The BED is defined as the dose at which at least 11 of 14 patients meet the target of complete suppression of alkylguanine-DNA alkyltransferase levels. Patients are followed at day 11, at weeks 2, 4, 6, 8, and 12, at months 6, 9, and 12, every 6 months for 4 years, and then annually for 5 years. PROJECTED ACCRUAL: Approximately 20 patients will be accrued for this study within 2 years.
