Outcome Measures

Primary Outcomes (1)

  • Mean Change From Observation Phase (OP) in the Number of Migraine Days Per Month Over Entire DBT Phase (Weeks 1 to 12)

    A migraine day was defined as any calendar day in which the participant experienced a qualified migraine headache (onset, continuation, or recurrence of the migraine headache). A qualified migraine headache was defined as a migraine with or without aura, lasting for \>=30 minutes, and meeting either \>=2 of the pain features: unilateral location; pulsating quality; moderate or severe pain intensity; aggravation by or causing avoidance of routine physical activity OR \>=1 of the associated symptoms: nausea and/or vomiting; photophobia and phonophobia. The number of migraine days per month were prorated to 28 days and derived for a month in on-DBT efficacy analysis period as follows: 28\*(total number of migraine days through Month 3 \[Weeks 1 to 12\]/ (total number of e-diary efficacy data days through Month 3 \[Weeks 1 to 12\]). Mean change in number of migraine days per month in DBT phase as compared to OP phase was calculated and reported in this outcome measure.

    Observation phase (from 31 days prior to randomization), DBT phase (through Month 3 [Week 1 to 12])

Secondary Outcomes (19)

  • Percentage of Participants With Greater Than Equal to (>=) 50 Percent (%) Reduction From OP in Number of Moderate to Severe Migraine Days Per Month Over the Entire DBT Phase (Weeks 1 to 12)

    DBT phase (through Month 3 [Week 1 to 12])

  • Mean Change From OP in the Number of Migraine Days Per Month in the Last 4 Weeks (Weeks 9 to 12) of DBT Phase

    Observation phase (from 31 days before randomization), Week 9 to Week 12 of the DBT phase

  • Mean Change From OP in the Number of Migraine Days Per Month in the First 4 Weeks (Weeks 1 to 4) of DBT Phase

    Observation phase (from 31 days before randomization), Week 1 to Week 4 of the DBT phase

  • Mean Number of Acute Migraine-Specific Medication Days Per Month Over the Entire DBT Phase (Weeks 1 to 12)

    DBT phase (through Month 3 [Week 1 to 12])

  • Mean Change From Baseline in the Migraine-Specific Quality-of-Life Questionnaire (MSQoL) Version 2.1 Restrictive Role Function Domain Score at Week 12 of the DBT Phase

    Baseline (Day 1), Week 12 of the DBT phase
