Brief summary
The MoveDMD study is a 3-part, Phase 1/2, multi-site study to evaluate the safety, efficacy, pharmacokinetics (PK) and pharmacodynamics (PD) of edasalonexent (also known as CAT-1004) in pediatric patients with a genetically confirmed diagnosis of DMD. Male patients from ≥4 to \<8 years of age will be enrolled. Edasalonexent is an orally administered small molecule targeted to inhibit activated NF-κB, a molecule that is activated from infancy in DMD and which is central to causing muscle damage and preventing muscle regeneration. Data on magnetic resonance imaging of the lower and upper leg muscles, physical function (including timed function tests) and muscle strength will be studied.
Detailed description
Part A was a 1-week, open-label study to assess safety, tolerability, pharmacokinetics and biomarkers for three dose levels of edasalonexent and is now complete. Part B was a randomized, double-blind, placebo-controlled, multiple dose study to evaluate the safety, efficacy, PK, and PD of edasalonexent over 12 weeks. Patients who participated in Part A also participated in Part B, along with newly enrolled patients. Patients received either edasalonexent 67 mg/kg/day, edasalonexent 100 mg/kg/day, or placebo in Part B. Part B is now complete. Following completion of Part B, patients receive edasalonexent for 138 weeks in Part C, the open-label portion of the MoveDMD study. Patients on the 67 mg/kg/day treatment moved to the 100 mg/kg/day treatment. Patients on the 100 mg/kg/day treatment remained on the 100 mg/kg/day treatment. If clinically indicated, concomitant treatment with eteplirsen (Exondys 51™) may be acceptable in patients with amenable gene mutations during Part C after the patient has been exposed to edasalonexent for 6 months. \*\*Following completion of MoveDMD Part C, access to edasalonexent for trial participants will continue through the open-label extension study, GalaxyDMD.\*\*

Recruitment details
This was a 3-part, Phase 1/2, multi-centre study conducted at 5 study centers in United States.
Pre-assignment details
A total of 32 patients were treated with edasalonexent in this study. 17 patients were enrolled in Part A and 16 completed 7 days of dosing, 1 patient screen failed due to inability to comply with study procedures and did not continue to Part B. A total of 31 patients (16 subjects from Part A and 15 New subjects who entered Part B) were enrolled in Part B, and all completed the 12 weeks of dosing. All 31 patients included in Part B enrolled in the open-label long-term extension phase, Part C.

Change From Baseline to Week 12 in the Lower Leg Composite of the MRI T2 Relaxation Time (LLC5-T2) - Part B
The LLC5-T2 calculated from the unweighted average of the T2 relaxation times of all 5 lower leg muscles for each patient at each evaluation (the medial gastrocnemius, peroneals, soleus, tibialis anterior, and tibialis posterior muscles). Increases in LLC5-T2 relaxation time indicate muscle damage, inflammation, edema, and fat infiltration and are highly correlated with muscle fat
