1. Patient and/or parent or legal guardian must have the ability and be willing to provide written informed consent/minor assent prior to any study-related procedures. 2. Patient successfully completed the Phase 1 study with WVE-210201, WVE-DMDX51-001. 3. Willing and able to comply with scheduled visits, drug administration plan, laboratory tests, study restrictions, and all study procedures. 4. Stable pulmonary and cardiac function, as measured by: a. Reproducible percent predicted forced vital capacity (FVC) ≥50% b. Left ventricular ejection fraction (LVEF) >55% in patients <10 years of age and >45% in patients ≥10 years of age, as measured (and documented) by echocardiogram. 5. Sexually mature males must be willing to use contraception for the duration of the study, if the patient is sexually active. 6.

|
E.4 | Principal exclusion criteria |
1. Clinically significant medical finding on the physical examination other than DMD that, in the judgment of the Investigator will make the patient unsuitable for participation in, and/or unable to complete the study procedures. 2. Other prior or ongoing medical conditions including: a. Acute illness within Screening period; b. Abnormal physical findings, other than those associated with musculoskeletal findings attributable to DMD. 3. Laboratory abnormality, that, in the Investigator's opinion, could adversely affect the safety of the patient, make it unlikely that the course of treatment or follow up would be completed, or impair the assessment of study results. These include, but are not limited to: a. Renal insufficiency; b. Impaired hepatic function as measured by glutamate dehydrogenase (GLDH) ≥ 2.5x upper limit of normal (ULN) and Bilirubin ≥ 2x ULN (or INR ≥ 1.5x ULN; c. Activated partial thromboplastin time [aPTT] values above the ULN; d. Platelet count less than lower limit of normal (LLN). e. Any evidence of clinically significant structural or functional heart abnormality would prohibit participation in this study. f. Troponin I value above 2x ULN 4. Parent or legal guardian is directly or indirectly involved in the conduct and administration of this study as an Investigator, sub-investigator, study coordinator, or other study staff member, or the patient is a first-degree family member, significant other, or relative residing with one of the above persons involved directly or indirectly in the study. |
