Pelvic floor training for women with myotonic dystrophy
This study tests whether pelvic floor muscle training (exercises to strengthen the muscles that control urine flow) can help women with myotonic dystrophy type 1 who have bladder leakage. It's a gentle, non-surgical approach that may improve quality of life.
Jonquière, QuebecAges 18 years+ - NCT06523400RecruitingPhase 3
Mexiletine for myotonic dystrophy types 1 and 2
This trial tests a once-daily drug called mexiletine PR to see if it can help reduce muscle stiffness (myotonia) in people with myotonic dystrophy type 1 or 2. It may be a good option if you have a confirmed genetic diagnosis and are at least 16 years old.

Common questions
- Are there clinical trials for myotonic dystrophy type 1 (dm1)?
- Yes. Clin2 currently lists 24 recruiting myotonic dystrophy type 1 (dm1) studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a myotonic dystrophy type 1 (dm1) trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a myotonic dystrophy type 1 (dm1) trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
