Outcome Measures
Go to

Primary Outcome Measures :
  1. Mean change from the Observation Phase in the number of migraine days per month over the entire Double-blind Treatment Phase (Weeks 1-12) [ Time Frame: 3 months (12 weeks) ]
    Change from baseline in mean number of migraine days per month


Secondary Outcome Measures :
  1. Proportion of subjects with > 50% reduction from the Observation Phase (Weeks 1 to 12). [ Time Frame: 3 months (12 weeks) ]
    Number of moderate to severe migraine days per month over the entire Double-blind Treatment Phase

  2. Mean change from the Observation Phase. [ Time Frame: Weeks 9 to 12 ]
    Number of migraine days per month in the last 4 weeks of the Double-blind Treatment Phase.

  3. Mean change from the Observation Phase [ Time Frame: Weeks 1 to 4 ]
    number of migraine days per month in the first 4 weeks of the Double-blind Treatment Phase.

  4. Mean number of acute migraine-specific medication days per month. [ Time Frame: Weeks 1 to 12 ]
    Over the entire Double-blind Treatment Phase. Acute migraine-specific medications are triptans and ergotamine.

  5. Mean change from baseline in the Migraine-Specific Quality-of-Life Questionnaire (MSQ) restrictive role function. [ Time Frame: At Week 12 ]
    Domain score of the Double-blind Treatment Phase.

  6. Number and percentage of subjects with AEs by intensity. [ Time Frame: 24 Weeks ]
    Serious adverse events (SAEs), AEs leading to study drug discontinuation, and grade 3 to 4 laboratory test abnormalities during the Double-blind Treatment and Open-label Extension Phases.

  7. Number and percentage of subjects treated with rimegepant with AST or ALT elevations. [ Time Frame: 24 Weeks ]
    >3x ULN concurrent (i.e., on the same laboratory collection date) with total bilirubin > 2x ULN during the Double-blind Treatment and Open-label Extension Phases.

  8. Number and percentage of subjects treated with rimegepant with hepatic-related AEs [ Time Frame: 24 Weeks ]
    By intensity and hepatic-related AEs leading to study drug discontinuation during the Double-blind Treatment and Open-label Extension Phases.
