- Change From Baseline in the Frequency of Headache Days [ Time Frame: Baseline, Week 108 ]Mean change from Baseline in frequency (number) of headache days during the 28 day period ending with Week 108. A headache day was defined as a day (00:00 to 23:59) for which the participant reported a headache in the patient diary with 4 or more continuous hours of headache. A negative change from Baseline indicates improvement.
- Change From Baseline in the Frequency of Headache Days [ Time Frame: Baseline, Week 60 ]Mean change from Baseline in frequency (number) of headache days during the 28 day period ending with Week 60. A headache day was defined as a day (00:00 to 23:59) for which the participant reported a headache in the patient diary with 4 or more continuous hours of headache. A negative change from Baseline indicates improvement.
- Change From Baseline in Headache Impact Test Questionnaire (HIT-6) Total Score [ Time Frame: Baseline, Week 60, Week 108 ]The HIT-6 measures the impact of headache and treatment 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 4-week period. The total possible score ranges from 36 (no impact) to 78 (worst impact). A negative change from Baseline indicates an improvement, and a positive change from Baseline indicates a worsening.
