Study Endpoints

Primary Endpoints

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)

Part A: Safety: Proportion of patients with adverse events (AEs)
Day 1 (initial dose) up to 24 weeks after the last dose of Part A
Part B: Pharmacodynamics: Dystrophin level (% normal dystrophin) as assessed by Western blot of muscle tissue following multiple doses of WVE-N531
At Week 26 and at Week 50 of Part B
Part C: Pharmacodynamics: Change from baseline dystrophin level (% normal dystrophin) as assessed by a validated assay analysis in muscle tissue following multiple doses of WVE-N531
At Baseline and following 24 weeks of treatment in Part C

Secondary Endpoints

North Star Ambulatory Assessment (NSAA) (Version 2.0) composite score, each item assessed using a 3 point scale, including:
At baseline Week 0 through Week 96
Performance of the Upper Limb (PUL) (Version 2.0) (measured by total score and score of high level shoulder dimension, Mid-level Elbow Dimension, Distal Wrist and Hand Dimension)
At baseline Week 0 through Week 96
Stride Velocity 95th Centile (SV95C) (collected in 3 consecutive weeks)
At baseline Week 0 through Week 96

Frequently asked questions about WVE-N531

What is WVE-N531 used for?

WVE-N531 is an investigational therapy being developed for Duchenne Muscular Dystrophy, a genetic muscle-wasting disease. It is designed for patients whose disease is amenable to exon 53 skipping, and it carries a Rare Pediatric Disease designation from the FDA. It is in Phase 2 clinical development and has not been approved for any use.

What does WVE-N531 target?

WVE-N531 targets DMD exon 53. By directing exon 53 skipping in the dystrophin gene transcript, the therapy aims to restore a shortened but functional form of dystrophin in patients with Duchenne Muscular Dystrophy whose mutations are compatible with skipping this exon. Trial eligibility is biomarker selected around this exon 53 population.

Who is developing WVE-N531?

WVE-N531 is being developed by Wave Life Sciences Ltd., which trades on Nasdaq under the ticker WVE. The company is running the clinical program in Duchenne Muscular Dystrophy, including an open-label Phase 1 study and a Phase 2 open-label extension study.

What phase is WVE-N531 in?

WVE-N531 is in Phase 2 clinical development for Duchenne Muscular Dystrophy. It is investigational and has not been approved by the FDA. The program includes a Phase 1 open-label study and a Phase 2 open-label extension study, and the FDA has granted it a Rare Pediatric Disease designation.

What clinical trials is WVE-N531 in?

WVE-N531 has two registered clinical trials. NCT04906460 is the Phase 1 open-label FORWARD-53 study in patients with Duchenne Muscular Dystrophy, active but not recruiting, with 25 participants across the United States, Jordan, and the United Kingdom. NCT07209332 is a Phase 2 open-label extension study enrolling by invitation in Jordan and the United Kingdom with 175 participants.

Who can enroll in WVE-N531 trials?

The WVE-N531 trials enroll male patients with Duchenne Muscular Dystrophy. The Phase 1 FORWARD-53 study accepts participants aged 4 years and older, and neither study includes healthy volunteers. Both are open-label and uncontrolled, and the Phase 2 extension study is enrolling by invitation only.
