Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

AOC 1001-CS1 is a randomized, double-blind, placebo-controlled, Phase 1/2 study to evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single and multiple-doses of AOC 1001 Administered Intravenously to Adult Myotonic Dystrophy Type 1 (DM1) patients (MARINA).

Part A is a single dose design with 1 cohort (dose level). In Part A, the patient duration is 6 months as the treatment period is 1 day followed by a 6 month follow-up period.

Part B is a multiple-ascending dose design with 2 cohorts (dose levels). In Part B, the patient duration is 6 months as the treatment period is 3 months followed by a 3 month follow-up period.
