Innovative Trial for NF2-Related Schwannomatosis
This study, called INTUITT-NF2, is testing several experimental treatments for people with NF2-related schwannomatosis (NF2-SWN), a condition that causes tumors like vestibular schwannomas (tumors on the nerve for hearing and balance), non-vestibular schwannomas, meningiomas, and ependymomas. The treatments being tested are Brigatinib, Neratinib, and a combination of Retifanlimab and Bevacizumab. The main goal is to see how many people respond to these drugs over two years. You might be able to join if you are 12 years or older, have a specific genetic change in the NF2 gene, or meet certain diagnostic criteria for NF2. The study is currently unclear about its recruitment status, but it plans to enroll 109 participants.
- Study design
- This is a Phase II 'basket' study, meaning it tests multiple drugs for different tumor types associated with NF2-SWN. It plans to enroll 109 participants into different treatment arms.
- What's involved
- You would undergo screening, potentially be assigned to an experimental treatment, and be observed for up to 10 years. If your tumors grow on one treatment, you might be able to switch to another experimental treatment.
- Compensation
- Not stated in the trial record.
- Follow-up
- Participants will be observed for up to 10 years, with the primary outcome measured at 2 years.
