What this Trial Is About
Researchers are conducting a Phase 3 clinical trial to evaluate the safety and effectiveness of AOC 1044, also known as delpacibart zotadirsen, for treating Duchenne Muscular Dystrophy DMD in boys aged 7 to 16 with specific gene mutations suitable for exon 44 skipping. This study is designed as a randomized, double-blind, placebo-controlled trial to assess the impact of this intravenous treatment on muscle function over time. Participants will be randomly assigned to receive either AOC 1044 or a placebo infusion every 6 weeks for 54 weeks, totaling 9 doses during the double-blind treatment period. After this, all participants can join an open-label extension where they receive AOC 1044 every 6 weeks for another 54 weeks, adding 9 more doses. Following the final dose at week 102, participants will have assessments at weeks 108 and 114 to evaluate safety and treatment effects. During the study, participants will undergo various assessments including tests for time to rise velocity, muscle strength, walking and climbing abilities, and quality of life measures. Muscle enzyme levels and global impressions of severity and change from both patients and caregivers will also be monitored. Safety and tolerability will be reviewed regularly by an independent committee. Overall participation lasts over two years, including screening, treatment, extension, and follow-up phases.

Who Can Participate
Eligibility Criteria
You may qualify if you...
- Ambulatory males with clinical and genetic diagnosis of Duchenne Muscular Dystrophy
- Genetic test confirming dystrophin gene mutation amenable to exon 44 skipping
- Aged 7 to 16 years at time of consent
- Time to Rise (TTR) and North Star Ambulatory Assessment (NSAA) completed within protocol parameters at screening
- On a stable corticosteroid regimen (including Vamolorone) for at least 6 months prior to Day 1, with anticipated stability during the study
You will not qualify if you...
- Previous cell or gene therapy treatment
- Treatment with another oligonucleotide within 6 months of informed consent (excluding COVID-19 RNA vaccines)
- Laboratory values outside protocol specified ranges at screening
- If on growth hormone, testosterone, or givinostat, must have stable regimen planned for study duration; excluded if stability prior to consent is less than 1 month for growth hormone/testosterone or less than 6 months for givinostat
