 (submitted: June 16, 2022)
Change From Baseline in North Star Ambulatory Assessment (NSAA) [ Time Frame: Baseline (Day 1) to Week 52 ]
To assess change from baseline in North Star Ambulatory Assessment(NSAA) Total Score at Wk52. NSAA is clinician-reported outcome instrument designed to measure ambulatory function in males with Duchenne muscular dystrophy(DMD). Patients asked to perform 17 different functional activities,including 10MWT,rising from sit to stand,standing on one leg,climbing & descending a step,stand from supine, lifting the head, standing on heels, & jumping. Each function activity will be scored as0=(unable to achieve independently),scored as1=(modified method but achieves goal independent of physical assistance from another),or scored as2=(no obvious modification of activity)or "Not Scored". If NSAA test was performed & any of the individual items are scored as "not scored"(i.e, for reasons unrelated to patients physical capabilities), corresponding total score will be set to missing. Sum of 17 scores will be used to form an ordinal total score(range 0-34).Higher scores imply better functional status

Cannot increase walking speed 4=Moderately adapted gait.

    To assess the change from baseline to Week 52 on the 4-Stair Climb. For timed function tests (TFTs) , the time will be set to 12 seconds and the speed to 0 if the TFT assessment meets the following TFT grading criteria. Grade of 1(from a 6-point scale)1=Unable to climb 4 standard stairs(no time recorded) 2=Climbs 4 standard stairs "marking time"(climbs one foot at a time, with both feet on a step before moving to next step), uses both arms on one or both handrails or uses 1 handrail and the other arm pushes on the leg 3=Climbs 4 standard stairs "marking time", using one arm on one handrail or one hand pushing on leg or body 4=Climbs 4 standard stairs "marking time", not needing handrail and not using hands to push on leg 5=Climbs 4 standard stairs alternating feet, needs handrail/s for support or uses arms to push on the leg or body 6=Climbs 4 standard stairs alternating feet, not needing handrail support or using arm to push on the leg
  • Safety and Tolerability Measured by Number of Treatment- Emergent Adverse Events (TEAEs) and Serious Adverse Events (SAEs) [ Time Frame: Up to Week 52 ]
    Adverse events that occurred from the time of the administration of the first dose of investigational product (IP) through the end of the safety follow-up were considered treatment-emergent AEs (TEAEs). Serious adverse event (SAE).

Descriptive Information
Brief Title  ICMJE Phase III Study of Edasalonexent in Boys With Duchenne Muscular Dystrophy
Official Title  ICMJE A Randomized, Double-Blind, Placebo-Controlled, Global Phase 3 Study of Edasalonexent in Pediatric Patients With Duchenne Muscular Dystrophy
Brief Summary

The PolarisDMD study is a Phase 3, global study to evaluate the efficacy and safety of edasalonexent in pediatric patients with a genetically confirmed diagnosis of DMD. Male patients from 4-7 years of age (up to 8th birthday) will be enrolled.

Edasalonexent is an orally administered small molecule that inhibits NF-kB, which is the key link between loss of dystrophin and disease pathology and plays a fundamental role in the initiation and progression of skeletal and cardiac muscle disease in DMD.

Detailed Description

The study includes a 52-week, randomized, double-blind, placebo-controlled period, followed by a 2-week follow- up. Approximately 125 boys with DMD will be enrolled in this trial, with 2 boys receiving edasalonexent for every 1 boy receiving placebo.

Following completion of the treatment period, patients may elect to continue in a separate open-label extension study.
