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.
