Timeframe: 2 to 4 hours postdose

Subject-rated treatment overall satisfaction was based on a 7-point scale at 2 and 4 hours postdose during each DB treatment period. The difference between the subject-rated study drug treatment satisfaction score at 2 and 4 hours postdose and the baseline PPMQ-R (Patient Perception of Migraine Questionnaire) response for the same question were summarized by treatment group (global satisfaction item at baseline asked about the subject's usual migraine treatment). The possible values of the subject treatment satisfaction scale were: 1=very satisfied, 2=satisfied, 3=somewhat satisfied, 4=neither satisfied nor dissatisfied, 5=somewhat dissatisfied, 6=dissatisfied, 7=very dissatisfied. A decrease in values indicates improvement from baseline.

SECONDARY outcome

Timeframe: 24 hours postdose

Patient Perception of Migraine Questionnaire-Revised had 30 questions assessing subject's satisfaction with migraine medication, including 3 global items \& 4 subscales (i.e., efficacy, function, ease of use, tolerability). A 5-point scale (1-Not At All to 5-Extremely) was used for tolerability subscale questions; a 7-point scale (1-Very Satisfied to 7-Very Dissatisfied) was used for all other subscales and global items. Total score was average of efficacy/function/ease of use subscale scores. Each subscale \& total scores were transformed to range from 0-100, with higher scores indicating better satisfaction or tolerability. Total raw score/global items were not transformed. The total raw score could range from 17 (min) to 119 (max), with lower scores indicating better satisfaction. Change from baseline scores at 24-hour-postdose for each subscale score, global item score, total score, \& total raw score were summarized by treatment group below.
