Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Change from baseline in the Eating Disorder Examination (EDE) global score [ Time Frame: Week 4 ]
    The EDE is a structured clinical interview (investigator rated) used to measure severity of the characteristic psychopathology of eating disorders


Secondary Outcome Measures :
  1. Safety [ Time Frame: Up to 12 weeks ]
    Proportion of patients with adverse events (AEs)

  2. Change from baseline in Yale-Brown Obsessive Compulsive Scale (Y-BOCS) [ Time Frame: Week 4 ]
    The Y-BOCS self-rated version consists of a 10 item measure with a total score ranging from 0 to 40, with higher scores indicating increased severity of symptoms

  3. Change from baseline in weight [ Time Frame: Up to 12 weeks ]
