Bevacizumab for Symptomatic Vestibular Schwannoma in Neurofibromatosis Type 2 (NF2)

United States14 participantsStarted 2010-10

Plain-language summary

People who have neurofibromatosis type 2 (NF2) can have tumors that grow on the auditory nerves and cause hearing loss. These tumors are called vestibular schwannomas (VSs), or acoustic neuromas. People with NF2 can also get schwannomas in other parts of their body, as well as tumors called meningiomas and ependymomas. Because VSs can cause hearing loss, many people with NF2 will have treatment to preserve their hearing. This treatment usually involves surgery. Because surgery has risks and is not able to help everyone with VSs, other methods of treatment are being explored. One area of exploration is looking to see if there is a drug that can be taken that might prevent the VSs from growing larger and causing hearing loss or brainstem compression. This study is exploring whether a drug that is approved by the FDA and is currently used to treat other tumors might also work to treat VSs. Based on people who have taken this drug to treat VSs already, there is some reason to think that it might be helpful to certain people with NF2. People enrolled in this study will receive the drug one time every three weeks for one year by infusion. This study will follow subjects over the course of the year that the person is taking the drug and for six months after the drug is stopped. This study is recruiting people who have NF2 and are currently having symptoms of tinnitus, dizziness, and/or hearing loss from their VSs. If you have NF2 and are currently having symptoms caused by your VSs, you may be eligible to participate.

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?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
