Super-Selective Intraarterial Intracranial Infusion of Avastin (Bevacizumab)

Plain-language summary
The high-grade malignant brain tumors, glioblastoma multiforme (GBM) and anaplastic astrocytoma (AA), 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 durations of only 9-12 months for GBM, and 3-4 years for AA. 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). Superselective Intraarterial Cerebral Infusion (SIACI) is a technique that can effectively increase the concentration of drug delivered to the brain while sparing the body of systemic side effects. One currently used drug called, Bevacizumab (Avastin) has been shown to be active in human brain tumors but its actual CNS penetration is unknown. This phase I clinical research trial will test the hypothesis that Bevacizumab can be safely used by direct intracranial superselective intraarterial infusion up to a dose of 10mg/kg to ultimately enhance survival of patients with relapsed/refractory GBM/AA. By achieving the aims of this study we will determine the toxicity profile and maximum tolerated dose (MTD of SIACI Bevacizumab. We expect that this project will provide important information regarding the utility of SIACI Bevacizumab therapy for malignant glioma, and may alter the way these drugs are delivered to our patients in the near future.

INCLUSION
* Male or female patients of greater or equal18 years of age.
* Patients with a documented histologic diagnosis of relapsed or refractory glioblastoma multiforme (GBM), anaplastic astrocytoma (AA)
* Patients with a histologically confirmed low-grade brain tumor who relapse with an enhancing tumor on MRI can be evaluated for toxicity only.
* Patients must have at least one confirmed and evaluable tumor site.
\*A confirmed tumor site is one in which is biopsy-proven. NOTE: Radiographic procedures (e.g., Gd-enhanced MRI or CT scans) documenting existing lesions must have been performed within three weeks of treatment on this research study.
* Patients must have a Karnofsky performance status greater or equal to 60% (or the equivalent ECOG level of 0-2) (see Appendix A; Performance Status Evaluation) and an expected survival of greater or equal to three months.
* Patients must be able to understand informed consent. Informed consent must be obtained at the time of patient screening.
* Because of known concerns with Avastin and wound healing, all craniotomy patients are eligible for the treatment if they have had a craniotomy \> two weeks prior to IA therapy. Craniotomy after SIACI bevacizumab therapy should wait 4 weeks.
* Pre-enrollment coagulation parameters (PT and PTT) must be less than or equal to1.5X the IUNL.
* Patients must have adequate hematologic reserve with WBC greater than or equal to 2800/mm3, absolute neutrophils greater than or equal to1500/mm3 a…
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
