Phase 1/2 Study of AOC 1020 in Participants With Facioscapulohumeral Muscular Dystrophy (FSHD)

AOC 1020-CS1 is a first-in-human, 3-part, multi-center, Phase 1/2, randomized, double-blind, placebo-controlled study designed to evaluate safety, tolerability, pharmacokinetics and to explore pharmacodynamics and efficacy of single and multiple-doses of AOC 1020 administered intravenously in participants with FSHD Type 1 (FSHD1) and FSHD Type 2 (FSHD2). Cohort A comprises a placebo-controlled dose titration cohort (Cohort A1) which includes a nested single and multiple dose schedule. Cohort B comprises a placebo-controlled, nested single ascending dose (SAD)/multiple ascending dose (MAD) cohort (Cohort B1). Cohort C comprises a randomized, placebo-controlled, expansion cohort (Cohort C1). For each of Cohorts A, B, and C the study duration is 12 months as the active treatment period is approximately 9 months for Cohorts A \& B and approximately 10.5 months for Cohort C followed by a 12-week follow-up period for Cohorts A \& B and a 7-week follow-up period for Cohort C. Once participants have completed active treatment with follow-up through 12 months, they may have the option to participate in a planned open-label extension. If patients do not immediately roll over into the open-label extension study or decline participation, they will be followed for 18 weeks after their last dose of study medication.
