- Change from baseline in mean monthly migraine days across the treatment period [ Time Frame: 12 Weeks ]Baseline is defined as the number of migraine days during the last 28 days prior to the randomization date.
- Change from baseline in mean monthly headache days across the 12-week treatment period [ Time Frame: 12 Weeks ]Baseline is defined as the number of migraine days during the last 28 days prior to the randomization date.
- Change from baseline in mean monthly acute medication use days across the 12-week treatment period [ Time Frame: 12 Weeks ]Baseline is defined as the number of migraine days during the last 28 days prior to the randomization date.
- At least a 50% reduction in 3-month average of monthly migraine days [ Time Frame: 12 Weeks ]Defined as participants with at least a 50% reduction from baseline in monthly migraine days
- Change from baseline in MSQ v2.1 Role Function-Restrictive domain score at Week 12 [ Time Frame: 12 Weeks ]The MSQ v2.1 is a 14-item questionnaire designed to measure health-related quality of life impairments attributed to migraine in the past 4 weeks. It is divided into 3 domains: Role Function Restrictive assesses how migraines limit one's daily social and work-related activities; Role Function Preventive assesses how migraines prevent these activities; and the Emotional Function domain assesses the emotions associated with migraines.
- Change from baseline in mean monthly Performance of Daily Activities domain score of the AIM-D across the 12-week treatment period. (Excluding participants from Europe & Canada) [ Time Frame: 12 Weeks ]The Activity Impairment in Migraine-Diary (AIM-D) is an 11-item daily diary measure that assesses the impact of migraine and is comprised of two domains that evaluate performance of daily activities (7 items) and physical impairment (4 items).
- Change from baseline in mean monthly Physical Impairment domain score of the AIM-D across the 12-week treatment period. (Excluding participants from Europe & Canada) [ Time Frame: 12 Weeks ]The Activity Impairment in Migraine-Diary (AIM-D) is an 11-item daily diary measure that assesses the impact of migraine and is comprised of two domains that evaluate performance of daily activities (7 items) and physical impairment (4 items).
- Change from baseline in the Headache Impact Test (HIT-6) total score at Week 12 (Participants in Europe and Canada only) [ Time Frame: 12 Weeks ]
The HIT-6 is a 6-question assessment used to measure the impact headaches have on a participant's ability to function on the job, at school, at home, and in social situations. It assesses the effect that headaches have on normal daily life and the participant's ability to function.
Responses are based on frequency using a 5-point scale ranging from "never" to "always." The HIT-6 total score, which ranges from 36 to 78, is the sum of the responses - each of which is assigned a score ranging from 6 points (never) to 13 points (always).
