Trial Outcomes & Findings for EPI-743 for Metabolism or Mitochondrial Disorders (NCT NCT01642056)
NCT ID: NCT01642056
Last Updated: 2021-04-14
Results Overview
NPMDS is a semi-quantitative clinical rating scale that evaluates the progression of mitochondrial disease in pediatric patients. The NPMDS scale provides an assessment of the progression of mitochondrial disease. Scores from Parts I-III are added to get a value between 0 and 130, with higher scores representing more severe disease.

EPI-743, Then Placebo
Received EPI-743, 15mg/kg up to a maximum dose of 200 mg orally or via gastric tube three times daily with meals, then placebo three times daily orally or via gastric tube with meals. EPI-743 is structurally related to Vitamin E and can be broadly classified as an antioxidant.
