Official Title: Phase I Trial of Super-Selective Intraarterial Cerebral Infusion of Bevacizumab (Avastin) for Treatment of Vestibular Schwannoma (Acoustic Neuroma

Brief Summary: A recent study by Plotkin et al. showed that bevacizumab (Avastin) treatment was followed by clinically meaningful hearing improvement, tumor-volume reduction, or both in some, but not all, patients with Vestibular Schwannoma (VS) who were at risk for complete hearing loss or brain-stem compression from growing VS. Because of the promising results in preliminary studies of Bevacizumab and because of significant experience with the safety of the dosages proposed in this study, this study will offer a safe treatment for patients with VS. Therefore, 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 and hearing function of patients with VS.

Detailed Summary:

Newer techniques in interventional neuroradiology have allowed for a more selective delivery of catheters higher up into the arterial tree where agents such as chemotherapies, can be delivered without the risk of adverse affects such as blindness. In fact, studies here at Cornell have developed very new and exciting super selective intraarterial delivery treatment for Retinoblastoma and Malignant Glioma brain tumors with little toxicity. Therefore, this trial will ask one simple question: Is it safe to deliver a first dose of Avastin intraarterially using these super selective delivery techniques instead of the standard intravenous route of administration? This should not only increase the amount of drug that gets to the VS but also spare them of any adverse effects from a less selective delivery. During that single dose of intraarterial Avastin, they will also receive a dose of mannitol that opens up the blood brain barrier to improve delivery of the agent to the tumor. After that single dose of Mannitol and Avastin intraarterially, the patient will be evaluated for 4 weeks to assess for toxicity. If no toxicity, then the will go on and get MRI of the brain every two months to assess for response up to 12 months. After this, the subject is done with the "experimental" aspects of the protocol. This is a Phase I trial that is designed to test the safety of the single dose intraarterial delivery of Avastin and Mannitol,.

To summarize:

Current Standard of Care: Surgery or radiosurgery: IV Avastin

Experimental portion of this proposal:

Day 0: Intraarterial Avastin single dose (starting at 2mg/kg and up to 10mg/kg) after Mannitol to open the blood brain barrier Day 28 (and every two months thereafter): MRI brain with co
