Expected Enrollment 24A minimum of 24 patients will be accrued for this study within 3 years. Outline This is a dose-escalation study. Patients are stratified according to tumor location (posterior fossa tumors vs all other brain tumors). Patients receive benzoporphyrin monoacid ring A (BPD-MA) IV preoperatively. Approximately 3 hours after BPD-MA administration, patients undergo craniotomy with photoillumination of the tumor. Patients with tumors greater than 2 cm in diameter also undergo gross tumor resection. Cohorts of 3-6 patients receive escalating doses of BPD-MA until the maximum tolerated dose (MTD) is determined. The MTD is defined as the dose immediately preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Three additional patients are treated at the MTD. Patients are followed at 4 and 6 weeks, every 3 months for 1 year, every 6 months for 1 year, and then annually thereafter.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol. Back to Top |
