HIV drug repurposed to fight muscle inflammation
NCT ID NCT07668505
First seen Jun 26, 2026 · Last updated Jul 01, 2026 · Updated 3 times
Summary
This study tests whether Maraviroc, a drug currently used for HIV, can reduce muscle inflammation and improve function in adults with myositis that hasn't responded to standard treatments. Ten participants will take a daily 300mg tablet for 12 weeks and undergo muscle biopsies and function tests. The goal is to see if the drug can help control the disease.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Maraviroc (Selzentry, Celsentri)
- What this could lead to
- If it works, this could offer a new treatment option for people with myositis who haven't responded to standard therapies.
- What could go wrong
- This is a very small, early-phase trial with only 10 participants and no placebo group, so results may not be reliable or apply to everyone. The drug may not improve symptoms or could cause side effects.
