Assessment (NSAA) Total Score in pediatric patients with Duchenne muscular dystrophy (DMD) |

To assess the safety and tolerability of edasalonexent in pediatric patients with DMD
To assess the effects of edasalonexent on physical function as measured by the 10-meter walk/run test (10MWT), time
to stand from supine, and the 4-stair climb in pediatric patients with DMD |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
A patient must meet all the following criteria to be eligible for this study.
1. Written consent/assent by patient and/or legal guardian as per regional and/or Institutional Review Board
(IRB)/Independent Ethics Committee (IEC) requirements
2. Diagnosis of DMD based on a clinical phenotype with increased serum creatine kinase (CK) and documentation of
mutation(s) in the dystrophin gene known to be associated with a DMD phenotype
3. Male sex by birth
4. Age ≥4.0 to <8.0 years (at the time of consent)
5. Able to perform stand from supine without assistance in ≤ 10 seconds
6. Able to perform the 10MWT and 4-stair climb
7. Able to swallow placebo capsules at the Screening Visit
8. Followed by a doctor or medical professional who coordinates Duchenne care on a regular basis and willingnessto disclose patient's study participation with medical professionals. |
|
E.4 | Principal exclusion criteria |
A patient who meets any of the following criteria will be excluded from this study.
1. Use of corticosteroids within 24 weeks prior to Day 1Íž use of inhaled, intranasal, and topical corticosteroids is
permitted
2. Use of an investigational drug, idebenone, or dystrophin-focused therapy within 4 weeks or a period of 5 half-lives duration prior to Day 1 (whichever is longer) or ongoing participation in any other therapeutic clinical trial. Exception: Patients who have received at least 24 weeks of a stable dose of eteplirsen prior to Day 1, and expected to continue treatment, will be eligible.
3. Use of the following within 4 weeks prior to Day 1: immunosuppressive therapy, warfarin, phenytoin, S-mephenytoin,
cyclosporine, dihydroergotamine, ergotamine, fentanyl, alfentanil, pimozide, quinidine, sirolimus, tacrolimus, or
paclitaxel
4. Use of human growth hormone within 3 months prior to Day 1
5. Documented positive hepatitis B surface antigen, hepatitis C antibody, or human immunodeficiency virus (HIV) or a
known risk factor for hepatitis such as a blood transfusion within 12 weeks prior to Day 1
6. Hemoglobin <10.5 g/dL
7. Abnormal gamma-glutamyl transferase (GGT) (>laboratory’s upper limit of normal [ULN])
8. Other prior or ongoing medical condition, known hypersensitivity to omega-3 fatty acids, physical findings, ECG
findings, or laboratory abnormality (including but not limited to renal insufficiency or impaired hepatic function) that, in the Investigator’s opinion, could adversely affect the safety of the patient, make it unlikely that the course of Treatment or follow-up would be completed, or impair the assessment of study results (e.g., a gastrointestinal condition that would impair fat absorption)
9. In the Investigator’s opinion, unwilling or unable for any reason (e.g., attentional or behavioral issues) to complete all study assessments and laboratory tests and comply with scheduled visits, administration of drug, and all other study procedures. |
