Description

Summary

AOC 1044-CS1 (EXPLORE44) is a Phase 1/2 study to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamic effects of single and multiple ascending doses of AOC 1044 in healthy adult volunteers and participants with DMD mutations amenable to exon 44 skipping.

Part A is a single dose design with multiple cohorts (dose levels) in healthy adult volunteers.

Part B is a multiple-ascending dose design with 3 cohorts (dose levels) in participants with Duchenne.
