- 75% Migraine Responder Rate [ Time Frame: 12 Weeks ]Participants with an average reduction in migraine days of at least 75% over Weeks 1 to 12, as compared with baseline.
- 50% Migraine Responder Rate [ Time Frame: Weeks 1-12 ]Participants with an average reduction in migraine days of at least 50% over Weeks 1 to 12, as compared with baseline
- 50% Headache Responder Rate [ Time Frame: Weeks 1-12 ]Participants with an average reduction in headache days of at least 50% over Weeks 1 to 12, as compared with baseline
- 100% Headache Responder Rate [ Time Frame: Weeks 1-12 ]Participants with an average reduction in headache days of at least 100% over Weeks 1 to 12, as compared with baseline
- 100% Migraine Responder Rate [ Time Frame: Weeks 1-12 ]Participants with an average reduction in migraine days of at least 100% over Weeks 1 to 12, as compared with baseline
- The Change From Baseline in Monthly Headache Days, Weeks 1-12 [ Time Frame: Weeks 1-12 ]Monthly headache days, as measured by eDiary. 4-weekly intervals averaged across weeks 1-12.
- The Change From Baseline in Monthly Migraine Days, Weeks 1-12 [ Time Frame: Weeks 1-12 ]Monthly migraine days, as measured by eDiary. 4-weekly intervals averaged across weeks 1-12.
- Change From Baseline in Percentage of Severe Migraines [ Time Frame: Weeks 1-12 ]The change from baseline in percentage of migraines that are classified as severe over Weeks 1-12
- Change From Baseline in Percentage of Severe Headaches [ Time Frame: Weeks 9-12 ]The change from baseline in percentage of headaches that are classified as severe over Weeks 9-12
- The Change From Baseline to Week 12 in HIT-6 Total Score [ Time Frame: Baseline to 12 ]The HIT-6 measures the impact of headache on the participant's functional health and well-being in 6 domains: pain; role functioning (ability to carry out usual activities); social functioning; energy or fatigue; cognition; and emotional distress assessed over the prior 12-week period. The total possible scores range from 36 (no impact) to 78 (worst impact). A score of 60 or above is labeled as "severe".
- Percent Change From Baseline in Headache Days [ Time Frame: Weeks 1-12 ]Monthly headache days, as measured by eDiary. 4-weekly intervals averaged across weeks 1-12.
- Percent Change From Baseline in Migraine Days [ Time Frame: Weeks 1-12 ]Monthly migraine days, as measured by eDiary. 4-weekly intervals averaged across weeks 1-12.
- Time to First Migraine After Dosing [ Time Frame: Baseline to Week 49 (End of Study) ]The median number of days after dosing a participant had the next migraine using the eDiary as the recall method
- Change From Baseline in Monthly Migraine Attacks, Weeks 1-12 [ Time Frame: Weeks 1-12 ]The number of monthly migraine attacks summarized over Weeks 1-12. A migraine attack is defined as 1 continuously recorded migraine. One attack may result in multiple migraine days
- Change From Baseline in Monthly Headache Episodes, Weeks 1-12 [ Time Frame: Weeks 1-12 ]The number of monthly headache episodes as summarized over Weeks 1-12. A headache episode is defined as 1 continuously recorded headache. One episode may result in multiple headache days
- Change From Baseline in Monthly Migraine Hours, Weeks 1-12 [ Time Frame: Weeks 1-12 ]Migraine hours are the sum of the duration of migraines within 4 week intervals, and the average 4 week duration within 12 week intervals.
- Change From Baseline in Monthly Headache Hours, Weeks 1-12 [ Time Frame: Weeks 1-12 ]Headache hours are the sum of the duration of headaches within 4 week intervals, and the average 4 week duration within 12 week intervals.
- Change From Baseline to Weeks 9-12 in Percentage of Migraines With Use of Acute Medication [ Time Frame: Weeks 9-12 ]The percent of migraines with acute medication usage. Participants with no migraines will be included with a rate of zero.
- Change From Baseline to Weeks 9-12 in Percentage of Headaches With Use of Acute Medication [ Time Frame: Weeks 9-12 ]The percent of headaches with acute medication usage. Participants with no headaches will be included with a rate of zero.
- Baseline and Change From Baseline in Short Form Health Survey (SF-36, Version 2.0) at Week 12 [ Time Frame: Baseline to Week 12 ]The SF-36 is a health survey containing 36 questions consisting of eight scaled scores to measure quality of life over the past 4 weeks (range: 0=worst to 100=best). Increases from baseline indicate improvement.
