Description

Summary

A Phase 3 Randomized, Double-Blind, Placebo-Controlled, Global Study to Evaluate the Efficacy and Safety of Intravenous Delpacibart Etedesiran (abbreviated del-desiran, formerly AOC 1001) for the Treatment of Myotonic Dystrophy Type 1

Official Title

A Phase 3 Randomized, Double-Blind, Placebo-Controlled, Global Study to Evaluate the Efficacy and Safety of Intravenous AOC 1001 for the Treatment of Myotonic Dystrophy Type 1

Details

The study consists of a Screening Period of up to 6 weeks and 54-week Treatment Period. The anticipated duration is approximately 60 weeks.

Participants will be randomized to receive an intravenous infusion of either del-desiran or placebo at the clinical study site every 8 weeks for a total of 7 doses. The final dose will occur at Week 48, followed by a final assessment at Week 54.

After completion of Week 54 assessments, eligible participants will have the option to enroll into an open label extension (OLE) study, pending regulatory approval.

An Independent Data Monitoring Committee (IDMC) comprised of members independent and external to the Sponsor will review safety, tolerability, and efficacy (as needed) data of this study at regular intervals.
