Measure Description: A migraine day was any calendar day on which the participant experienced a migraine headache qualified by duration and acute symptomatic medication use. The 4-week migraine days=total number of reported migraine days in diary divided by total number of days with diary records in each 4-week period multiplied by 28.

Measure Analysis Population Description: Modified-intent-to-treatment (mITT) Population included all randomized participants who received at least 1 dose of study treatment, had an evaluable baseline period of diary data, and had at least 1 evaluable post-baseline 4-week (Weeks 1-4, 5-8, and 9-12) of diary data.

Title Change From Baseline in Mean Monthly Migraine Days (Migraine/Probable Migraine Headache Days) Across the 12-Week Treatment Period
Hide Description Participants recorded daily duration of migraine in a diary. A migraine day was any calendar day on which the participant experienced a migraine headache qualified by duration and acute symptomatic medication use. The 4-week migraine days was defined as the total number of reported migraine days in diary divided by total number of days with diary records during each 4- week period and multiplied by 28. Each 4-week period was averaged. Negative change from Baseline indicates improvement.

4.Secondary Outcome
Title Change From Baseline in Mean Monthly Acute Medication Use Days Across the 12-Week Treatment Period
Hide Description Participants recorded allowed medication(s) to treat an acute migraine in the daily diary. The 4-week (monthly) acute medication use days was defined as the total number of reported acute medication use days in the diary divided by the total number of days with diary records during each 4-week period and multiplied by 28. Each 4-week period was averaged. A negative change from Baseline indicates improvement.
Time Frame Baseline (First 28 Days of Screening/Baseline Period) to Week 12
