Repeated Super-Selective Intraarterial Cerebral Infusion of Bevacizumab (Avastin) for Treatment of Newly Diagnosed GBM

Glioblastoma Multiforme Clinical Trial

Official title: Phase I/II Trial of Repeated Super-Selective Intraarterial Cerebral Infusion of Bevacizumab (Avastin) for Treatment of Newly Diagnosed Glioblastoma Multiforme

Status Completed

Clinical Trial Summary

The high-grade malignant brain tumors, glioblastoma multiforme (GBM), comprise the majority of all primary brain tumors in adults. This group of tumors also exhibits the most aggressive behavior, resulting in median overall survival of only 9-12 months. Initial therapy consists of either surgical resection, external beam radiation, or both. All patients experience a recurrence after first-line therapy, so improvements in both first-line and salvage therapy are critical to enhancing quality-of-life and prolonging survival. It is unknown if currently used intravenous (IV) therapies even cross the blood brain barrier (BBB). We have shown in a previous phase I trial that a single Superselective Intraarterial Cerebral Infusion (SIACI) of Bevacizumab (up to 15mg/kg) is safe and effective in the treatment of recurrent GBM. Therefore, this phase I/II clinical research trial is an extension of that trial in that we seek to test the hypothesis that repeated dosing of intra-arterial Bevacizumab is safe and effective in the treatment of newly diagnosed malignant glioma. By achieving the aims of this study we will also determine if repeated intra-arterial Bevacizumab improves progression free and overall survival in newly diagnosed patients. We expect that this project will provide important information regarding the utility of repeated SIACI Bevacizumab therapy for malignant glioma, and may alter the way these drugs are delivered to our patients in the near future.

Clinical Trial Description

The experimental aspects of this experimental plan will include:

1. Subjects will first be treated with Mannitol prior to chemotherapy infusion (Mannitol 20%; delivered IA, 12.5 mL over 2 minutes) in order to disrupt the blood brain barrier. This technique has been used in several thousand subjects in previous studies for the IA delivery of chemotherapy for malignant glioma.

2. Subjects will then be treated with repeated intraarterial delivery (SIACI) of Bevacizumab. Each subject will receive one dose of IA Bevacizumab on day 30, followed by chemoradiation. SIACI of Bevacizumab will be repeated every three months for a total of 3 infusions. ;
