WVE-N531: WVE-N531 is an antisense oligonucleotide (ASO)

Study summary

This is a Phase 2 open-label extension (OLE) study to evaluate the long-term safety, tolerability, efficacy, pharmacokinetics, and the pharmacodynamics (PD) through potential exploratory biomarker(s) of intravenous (IV) WVE-N531 in patients with DMD who participated in another study of WVE-N531. All patients will have rolled over from a previous study of WVE-N531.

Of note: if there will be a greater than 31-day gap between the last dose on the prior study and the FD on this study, the case should be discussed between the Investigator and Medical Monitor. Exclusion Criteria: 1. Any clinically significant medical finding or change during or following participation in the prior WVE-N531 study, other than DMD that, in the judgment of the Investigator, would affect the potential safety of the patient to receive WVE-N531 or interfere with participation in the study. 2. Any recreational substance use (including prescribed cannabinoids), with the exception of alcohol and nicotine, irrespective of legality, within 2 months prior to FD and/or unwilling to refrain from such use for the duration of the study.

Primary outcome measure(s)

  • Number of participants with treatment related adverse events as assessed by the following parameters: — Time Frame: Week 0 through Week 96
    * Complete Physical examination, including height and weight * Vital Signs (via blood pressure, temperature and pulse) * Safety Laboratory Tests (including complete blood cell count, urinalysis and clinical chemistry) * ECG (12- Lead single tracing) * ECHO (including left ventricular ejection fraction) * Pulmonary Function Tests (including Peak Flow Rate, Cough Peak Flow, Forced Vital Capacity and Maximum Inspiratory Pressure)
