Clinical Trial Alert: Expansion Therapeutics Seeks Participants for a Phase 1 DM1 Study

Researchers at Expansion Therapeutics are looking for adults with myotonic dystrophy type 1 (DM1) to participate in a phase 1 study. The goal of the study is to evaluate the safety of ERX-963. Researchers hope this therapy may improve symptoms of excessive daytime sleepiness and improve attention and memory.

All participants will receive one dose of ERX-963. The total study duration for each patient will be about one to two months, with four clinic visits. The primary endpoint for this study is safety and tolerability.

In order to be eligible to participate, candidates must meet the criteria below, along with additional study criteria:

• Must have a confirmed diagnosis of DM1 by genetic testing or clinical confirmation
• Must have had an age of DM1 onset greater than 16 years
• Must be between ages 18 and 65
• Must have an Epworth Sleepiness Scale of greater than 11 or must have long sleep periods of, on average, more than 10 hours a day

Travel support is available.
