Bevacizumab

Experimental portion of this proposal: This trial will have two experimental arms that will be open labeled and non-randomized. ARM 1 (If the patient has multifocal disease or leptomeningeal disease) Day 0: Intraarterial Bevacizumab single dose (15mg/kg) after Mannitol to open the blood brain barrier Day 28: Intravenous Bevacizumab (10mg/kg) every two weeks thereafter until disease progression on MRI scan. If progression occurs, repeat Intraarterial Bevacizumab single dose (15mg/kg) to area of progression and…

ARM 2 (If the patient has no multifocal disease or leptomeningeal disease) Day 0: Intraarterial Bevacizumab single dose (15mg/kg) after Mannitol to open the blood brain barrier Day 28: No biweekly IV Bevacizumab treatment If MRI shows progression then repeat Intraarterial Bevacizumab single dose (15mg/kg) to area of progression Repeat Cycle

The current standard of care for recurring GBM is for patients to receive Bevacizumab (Avastin) intravenously (IV) at 10mg/kg every two weeks until their tumor grows more than 25%. At that point, these patients are deemed treatment failures and are given another treatment.

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).

Live record on ClinicalTrials.gov →

• 18 years of age or older.
• Patients with a documented histologic diagnosis of relapsed or refractory glioblastoma multiforme (GBM), anaplastic astrocytoma (AA) or anaplastic mixed oligoastrocytoma (AOA).
• Patients must have at least one confirmed and evaluable tumor site. A confirmed tumor site is one in which is biopsy-proven.
• Patients must have a Karnofsky performance status 70% (or the equivalent ECOG level of 0-2).
• Patients must agree to use a medically effective method of contraception during and for a period of three months after the treatment period.

Inclusion criteria as written on the registry, trimmed. The full list, with exclusions, is on the live record.
