Study Summary
This trial is testing an antibody that may help relieve pain in people with schwannomatosis who are already taking other pain medications.
Who is the study for?
Adults over 18 with moderate to severe pain from schwannomatosis, who've tried and failed at least three standard treatments. They must not be pregnant or breastfeeding, agree to use two contraception methods if applicable, avoid certain medications including NSAIDs, and have normal organ/marrow function. Excluded are those with recent surgery or therapy for schwannomatosis-related tumors, history of allergic reactions to monoclonal antibodies, substance abuse within six months prior to screening.Check my eligibility
What is being tested?
The trial is testing Tanezumab—an antibody against nerve growth factor—to see if it can relieve pain in patients with schwannomatosis better than a placebo. Participants will continue their non-NSAID background therapy during the study.See study design
What are the potential side effects?
Tanezumab may cause side effects such as joint problems (like osteoarthritis), nerve damage that could lead to numbness or tingling sensations, potential heart issues like irregular heartbeat, and general symptoms like headache or nausea.

Frequently Asked Questions
These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.
What is the enrollment quota for this research project?
"This trial is not presently open to new applicants. It was initially listed on April 30th 2020, and the last update occured on October 15th 2022. Nevertheless, if you are looking for other studies related to pain management there are currently 569 trials that accept participants as well as a single clinical trial involving Tanezumab administration."
Answered by AI
Is this a pioneering clinical trial?
"At present, there is only one ongoing study of Tanezumab being conducted in a single city and nation. The initial research into this drug occurred during 2020 by Pfizer's team with 9 volunteers taking part. After its Phase 2 approval stage was finalized, 18334 more studies have been finished since then."
Answered by AI
Has the Food and Drug Administration authorized Tanezumab for medical use?
"Our team at Power has given Tanezumab a score of 2 due to the limited clinical evidence supporting its safety, despite it being in Phase 2 trials. No data currently exists that shows efficacy for this drug."
Answered by AI
Are there any remaining vacancies for participants in this experiment?
"This clinical trial has ceased actively recruiting participants. It was first posted on April 30th, 2020 and last updated October 15th, 2022. However, there are presently 569 studies seeking volunteers with pain-related conditions and one study searching for patients to participate in Tanezumab trials."
Answered by AI
Are there any comparable experiments that have employed Tanezumab?
"Presently, one ongoing research project is looking into Tanezumab and no trials are currently in Stage 3. Most of the investigations occur at sites located around Boston, yet there is also 1 further site running clinical trial with this drug."
