Study of ARO-DUX4 in Adult and Adolescent Patients With Facioscapulohumeral Muscular Dystrophy Type 1
Recruiting now · Phase 1/Phase 2 · Has a placebo group
Conditions studied: Facio-Scapulo-Humeral Dystrophy
In brief
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics (PK) and pharmacodynamics (PD) of ARO-DUX4 in participants with facioscapulohumeral muscular dystrophy Type 1 (FSHD1). In Part 1 of the study, participants will receive one dose of ARO-DUX4 or placebo. In Part 2 of the study, participants will receive 4 doses of ARO-DUX4 or placebo. Participants who complete Part 1 will have the option to re-screen and re-randomize into Part 2. All participants will undergo pre- and post-dose MRI-guided muscle biopsies (a total of 2 biopsies). Participants who complete Part 1 and enroll in Part 2 will be required to undergo an additional screening biopsy. Participants completing Part 1 or Part 2 may have the option to continue to receive drug in an open-label extension study or may be eligible to participate in later-stage clinical studies.
