New drug emrusolmin tested for Long-Term safety in rare brain disease
NCT ID NCT07197866
First seen Jun 25, 2026 · Last updated Sep 15, 2026 · Updated 10 times
Summary
This study is testing the long-term safety of an oral drug called Emrusolmin (TEV-56286) in 200 adults with multiple system atrophy (MSA), a rare and serious brain disorder. Participants who completed a prior trial will take the drug for about 100 weeks. The main goal is to see how many people have side effects or drop out due to side effects.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Emrusolmin (TEV-56286) taken orally
- What this could lead to
- If successful, this study could show that Emrusolmin is safe enough to use long-term for multiple system atrophy, potentially slowing disease progression.
- What could go wrong
- This is an early-phase, open-label extension trial focused on safety, not effectiveness. It is small (200 participants) and may not prove the drug works or is safe for everyone.
This is an AI summary of the original study and may miss details. Read our disclaimer.
