Percentage of Patients With Adverse Events28 DaysAn Adverse Event was considered any unfavorable and unintended sign, symptom, or disease associated with the use of the study drug, whether or not considered related to the study drug.

Secondary

MeasureTime frameDescription
Change From Baseline in Headache Impact Test-6 (HIT-6) Total ScoreBaseline, Day 28The HIT-6 is a 6 question 5-point scale used to measure the impact of headaches on daily life. The total score ranged from 36 (no impact) to 78 (worst impact). A negative number change from baseline indicates an improvement, and a positive number change from baseline indicates a worsening.
Physician Global Assessment of Outcome on a 3-Point ScaleBaseline, Day 28Physicians evaluated patient migraines as improved, no change, or worse compared to baseline.
