- Previous inclusion to another clinical trial with an Investigational Medicinal Product (IMP), within the 3 months or IMP washout period (whichever is longer) prior to the screening visit of the study
- Previously treated with a gene therapy drug for DMD, such as:
- any AAV mediated gene transfer products or any gene editing products in a clinical trial or in a clinical setting,
- if exons skipping drug was used, the last dose of exon skipping drug within 5 half-lives prior to the screening visit
- Concomitant participation to any other interventional clinical trial
