Study of ARO-DM1 in Subjects With Type 1 Myotonic Dystrophy
Recruiting now · Phase 1/Phase 2 · Has a placebo group
Conditions studied: Myotonic Dystrophy 1
In brief
This is a phase 1/2a double-blinded, placebo-controlled, dose-escalating study to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of single and multiple ascending doses of ARO-DM1 compared to placebo in male and female subjects with type 1 myotonic dystrophy (DM1).
