REPAIR-MS Trial Summary

This trial is testing a new drug for MS patients who have been diagnosed within the last 15 years. The goal is to see if the drug is safe and effective, and how it affects the brain.

Who is the study for?
Adults aged 18-70 with Multiple Sclerosis (MS) diagnosed within the last 15 years. Participants must have stable MS or be on specific therapies for at least 48 weeks. They should not have had recent relapses, metal implants affected by MRI, significant medical conditions, drug abuse history, pregnancy plans during and post-trial without contraception use, or a gold allergy.Check my eligibility
What is being tested?
The REPAIR-MS study is testing CNM-Au8 gold nanocrystals to see if they can improve brain metabolism in MS patients. This involves taking the treatment and having special brain scans called '31P-MRS imaging' over a period of 12 weeks to measure any changes.See study design
What are the potential side effects?
While side effects are not explicitly listed here, typical clinical trial concerns include potential allergic reactions to the gold nanocrystals and issues related to frequent MRI scans such as discomfort or claustrophobia.
