Primary Outcome Measures
NameTimeMethod
Mean Change From Observation Phase (OP) in the Number of Migraine Days Per Month Over Entire DBT Phase (Weeks 1 to 12)Observation Phase: 28 days prior to randomization and baseline; Entire DBT Phase: 12 weeks (Week 1 through 12)

A migraine day was defined as any calendar day in which participant experienced a qualified migraine headache (onset, continuation or recurrence of migraine headache). A qualified migraine headache was defined as migraine with or without aura, lasting for greater than or equal to (\>=) 30 minutes, and met at least one of the following criteria (A and/or B): A. \>=2 of the following pain features: a.

Aggravation by or causing avoidance of routine physical activity (e.g. walking or climbing stairs) B. \>= 1 of following associated symptoms: a. Nausea and/or vomiting b. Photophobia and phonophobia. The number of migraine days per month were prorated to 28 days and derived as follows: 28\*(total number of migraine days through Month 3\[Weeks 1 to 12\] in on-DBT efficacy analysis period)/ (total number of eDiary efficacy data days through Month 3\[Weeks 1 to 12\] in the on-DBT efficacy analysis period).

Acute migraine-specific medications were triptans and ergotamine. The number of acute migraine-specific medication days per month were prorated to 28 days and derived as follows: 28 \* (total number of acute migraine-specific medication days through Month 3 \[Week 1 to 12\] in the on-DBT efficacy analysis period)/ (total number of eDiary efficacy data days through Month 3 \[Week 1 to 12\] in the on-DBT efficacy analysis period).

Mean Change From Baseline in the Migraine-specific Quality of Life Questionnaire (MSQ) v 2.1 Restrictive Role Function Domain Score at Week 12DBT Phase: Baseline (before dose on Day 1), Week 12

MSQ v 2.1 is 14-item questionnaire that assessed impact of treatment on participant-reported quality of life across 3 domains: role function-restrictive, preventive, and emotional function. Restrictive role function domain consists of 7 items that describe how migraine limits one's daily social, work-related activities. Participants respond to items using a 6-point scale ranging from 1 (none of the time) to 6 (all of the time), which are assigned scores of 1 to 6, respectively. Response from each item of restrictive role function domain were added providing a possible raw score range of 7 (no impairment) to 42 (maximum impairment). Raw score range of restrictive role function domain was then transformed to a 0 (no impairment) to 100 (maximum impairment), higher scores = higher impairment.

Mean Change From Baseline in the Migraine Disability Assessment (MIDAS) Total Score at Week 12DBT Phase: Baseline (before dose on Day 1), Week 12

MIDAS is a retrospective, participant-reported, 5-item questionnaire that measured headache related disability as lost days due to headache from paid work or school, household work and non-work activities over past 3-months. The total score is calculated as the sum of item scores to all 5 questions on a scale of 0 (no disability) to 90 (maximum disability) resulting into overall possible MIDAS total score (range from 0 (no disability) to 450 (maximum disability). Higher scores = more severe disability.
