Percentage of Participants With 50% Response Rate Across the 3-month Treatment Period.
A migraine headache day is a calendar day on which a migraine headache or probable migraine headache occurred. Overall mean percentage across months 1 through 3 of participants with at least a 50% reduction in monthly migraine headache days from baseline (50% response rate) using a categorical pseudo likelihood-based repeated measures model for binary responder indicator with fixed, categorical effects of treatment, month, treatment by month, and continuous, fixed covariate of baseline monthly migraine headache day.
Time frame: Baseline, Month 1 through Month 3
Percentage of Participants With 75% Response Rate Across the 3-month Treatment Period.

A migraine headache day is a calendar day on which a migraine headache or probable migraine headache occurred. Overall mean was derived from the average of month 1 through month 3. Least square (LS) mean was calculated using mixed model for repeated measures (MMRM) model with treatment, month, and treatment-by-month interaction as fixed effects and baseline number of migraine headache days, and baseline-by-month interaction as continuous variables.

Mean Change From Baseline in the Number of Monthly Migraine Headache Days at Month 1
A migraine headache day is a calendar day on which a migraine headache or probable migraine headache occurred. LS mean was calculated using MMRM model with treatment, month, and treatment-by-month interaction as fixed effects and baseline number of migraine headache days, and baseline-by-month interaction as continuous variables.

Mean Change From Baseline in the Number of Monthly Migraine Headache Days at Month 2
A migraine headache day is a calendar day on which a migraine headache or probable migraine headache occurred. LS mean was calculated using MMRM model with treatment, month, and treatment-by-month interaction as fixed effects and baseline number of migraine headache days, and baseline-by-month interaction as continuous variables.
Time frame: Baseline, Month 2
Mean Change From Baseline in the Number of Monthly Migraine Headache Days at Month 3
A migraine headache day is a calendar day on which a migraine headache or probable migraine headache occurred. LS mean was calculated using MMRM model with treatment, month, and treatment-by-month interaction as fixed effects and baseline number of migraine headache days, and baseline-by-month interaction as continuous variables.
Time frame: Baseline, Month 3
Overall Mean Change From Baseline in the Number of Monthly Migraine Headache Days Requiring Medication for the Acute Treatment of Migraine or Headache Across the 3-month Treatment Period.
Number of monthly migraine headache days requiring medication for the acute treatment of headache is defined as the number of calendar days in a 30-day period on which migraine or probable migraine occurs and acute medication is used. Overall mean was derived from the average of month 1 through month 3. LS mean was calculated using MMRM model with treatment, month, and treatment-by-month interaction as fixed effects and baseline number of migraine headache days with acute medications use, and baseline-by-month interaction as continuous variables.

Mean Change From Baseline in the Migraine-Specific Quality of Life Questionnaire Version 2.1 (MSQ v2.1) at Month 3
The MSQ v2.1 is a 14-item questionnaire, participant-rated scale with a 4-week recall period that measures the impact of migraine on work or daily activities, relationships with family \& friends, leisure time, productivity, concentration, energy, tiredness \& feelings. It consists of 14 items that address 3 domains: * Role Function-Restrictive (RF-R), items 1-7 * Role Function-Preventive (RF-P), items 8-11 * Emotional Function (EF), items 12-14 Each item is scored from 1 (none of the time) to 6 (all of the time) and are reverse coded (value 6 to 1). Raw scores for each domain are computed as a sum of item responses, with the collective sum providing a total raw score. These were transformed to a 0-100 scale, with higher scores indicating better quality of life. LS mean was calculated using Analysis of covariance (ANCOVA) with main effects of treatment, the baseline number of migraine headache days category (\<8 vs \>=8), and the continuous fixed covariate of the baseline endpoint.

Mean Change From Baseline on the Migraine Disability Assessment Test (MIDAS) Total Score at Month 3
The MIDAS is a participant-rated scale that measures headache-related disability over a 3-month period. It consists of 5 items that measures number of days of work/school missed or days with productivity at work/school reduced to half or more; days with household work missed or days with productivity in household work reduced to half or more, and days of missed family/social/leisure activities. Each item has a numeric response range from 0 to 90 days; if days are missed from work/school or household work they are not counted as days with reduced productivity at work/school or household work. The numeric responses are summed to produce a total score ranging from 0 to 270. A higher value is indicative of more disability. LS mean was calculated using ANCOVA model with main effects of treatment, the baseline number of migraine headache days category (\<8 vs \>=8), and the continuous fixed covariate of the baseline endpoint.
