What researchers measure

Primary outcomes

  1. Primary Efficacy

    Change in plasma levels of reduced and oxidized glutathione from baseline to six months

    Time frame: 6 months

Secondary outcomes

  1. Secondary Endpoint

    Change in language skills as assessed by change from baseline to six months on the Clinical Evaluation of Language Fundamentals or Preschool Language Scale

    Time frame: 6 months

  2. Secondary Endpoint

    Change from baseline to six months in adaptive behavior and social skills as assessed by the Vineland Adaptive Behavior Scale-Second Edition (VABS), Social Responsiveness Scale (SRS), and computerized eye movement analysis

    Time frame: 6 months

  3. Secondary Endpoint

    Change from baseline to six months in stereotyped behavior and associated ASD symptoms as assessed by Aberrant Behavior Checklist (ABC), The Ohio Autism Clinical Impression Scale (OACIS), Repetitive Behavior Scale - Revised (RBS-R) and Autism symptoms questionnaire (ASQ)

    Time frame: 6 months

  4. Secondary Endpoint

    Change from baseline to six months in gastrointestinal function as assessed by Symptom Diary (stool frequency, abdominal symptoms and medications) and six-item GI severity index (6-GSI).

    Time frame: 6 months

  5. Secondary Endpoint

    Change from baseline to six months in caregiver strain experienced by parents of children with emotional and behavioral disorders as assessed by Caregiver Strain Questionnaire (CGSQ)

    Time frame: 6 months

  6. Secondary Endpoint

    Change from baseline to six months in intellectual function, attention and memory as assessed by Leiter-R test

    Time frame: 6 months

  7. Secondary Endpoint

    Change from baseline to six months in biomarkers of oxidative stress

    Time frame: 6 months

  8. Secondary Endpoint

    Pharmacokinetic Assessment of EPI-743 including maximal plasma concentration (Cmax), area under plasma concentration curve (AUC), apparent oral clearance, apparent volume of distribution and time to peak concentration

    Time frame: 6 months

  9. Safety Endpoint

    To examine the safety of EPI-743 in subjects with Autism Spectrum Disorder by examining drug-related adverse and serious adverse events

    Time frame: 8 months
