Conditions
Summary
This is a Phase 1b/2 open-label study to evaluate the safety, tolerability, pharmacokinetic (PK), pharmacodynamic (PD), and clinical effects of intravenous (IV) WVE-N531 in patients with Duchenne muscular dystrophy (DMD). To participate in the study, patients must have a documented mutation of the DMD gene that is amenable to exon 53 skipping intervention. This study has 3 parts, Part A, Part B, including Part B Extension Arm, and Part C. Part A is completed. Part B is completed. Following completion of Part B, all patients elected to continue to receive study drug in the optional Part B open-label Extension Arm. Part C has been added to the study and will enroll new patients.
Eligibility
Inclusion Criteria20
- Part A and Part B:
- Part A patients may be screened for Part B upon completion of a washout period of ≥18 weeks from last dose in Part A. New patients may also be screened for Part B
- Diagnosis of DMD based on clinical phenotype.
- Documented mutation in the DMD gene associated with DMD that is amenable to exon 53 intervention
- Score of ≥1 on item 1 or 2 of the shoulder component of the Performance of the Upper Limb (PUL) (Part B ).
- Ambulatory or non-ambulatory male
- Stable pulmonary and cardiac function, as measured by the following: (Part B):
- \. Reproducible percent predicted forced vital capacity (FVC) ≥50%; 2. 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 (ECHO) and/or cardiac magnetic resonance imaging (MRI), within 6 months prior to enrollment into the study.
- Adequate muscle at Screening to perform open muscle biopsies, preferably deltoid.
- \. Currently on a stable corticosteroid therapy regimen, defined as initiation of systemic corticosteroid therapy that occurred ≥6 months prior to Screening and no changes in dose ≤3 months prior to Screening visit (Part B ).
- Part C
- New patients to be screened for Part C.
- Diagnosis of DMD based on clinical phenotype.
- Documented mutation in the DMD gene associated with DMD that is amenable to exon 53 intervention
- Score of ≥1 on item 1 or 2 of the shoulder component of the Performance of the Upper Limb (PUL) .
- Ambulatory male
- Stable pulmonary and cardiac function, as measured by the following:
- \. Reproducible percent predicted forced vital capacity (FVC) ≥50%; 2. Left ventricular ejection fraction (LVEF) >55% in patients as measured (and documented) by echocardiogram (ECHO) and/or cardiac magnetic resonance imaging (MRI), within 6 months prior to enrollment into the study.
- \. Adequate muscle at Screening to perform open muscle biopsies, preferably deltoid.
- \. Currently on a stable corticosteroid therapy regimen, defined as initiation of systemic corticosteroid therapy that occurred ≥6 months prior to Screening and no changes in dose ≤3 months prior to Screening visit .
Exclusion Criteria4
- 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 completion of the study procedures.
- Part B and Part C: Major surgery within 3 months prior to Day 1 or planned major surgery for any time during the study.
- Part B: Diagnosis of active alcohol, cannabinoid, or other substance use disorder (except nicotine) within 6 months prior to the Screening visit
- Part C: Any recreational substance use (including prescribed cannabinoids), with the exception of nicotine, irrespective of legality, within 2 months prior to Screening and/or unwilling to refrain from such use for the duration of the study.
