New hope for DM1: Long-Term safety trial of PGN-EDODM1 now recruiting
NCT ID NCT07220603
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study is testing the long-term safety of an experimental drug called PGN-EDODM1 in 48 adults with myotonic dystrophy type 1 (DM1) who have already taken the drug in a previous study. Participants will receive the drug by IV infusion and be monitored for side effects. The goal is to see if the drug remains safe and tolerable over a longer period.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- PGN-EDODM1 (given by IV infusion)
- What this could lead to
- If successful, this study could support the continued development of PGN-EDODM1 as a treatment to control myotonic dystrophy type 1 symptoms.
- What could go wrong
- This is an early-phase, open-label extension study with no placebo group, so results are preliminary. The drug may still fail in larger trials or cause unexpected side effects.
