Design outcomes

Primary

MeasureTime frame
Main Objective: In a real-world population of adults with migraine, we would like to investigate whether 12.5 mg almotriptan is non-inferior to 50 mg ubrogepant in terms of pain freedom at 2 hours after drug intake. ;Secondary Objective: Not applicable;Primary end point(s): Pain freedom at 2 hours;Timepoint(s) of evaluation of this end point: 2 hours post-dose

Secondary

MeasureTime frame
Secondary end point(s): Exploratory endpoints: - absence of the most bothersome symptom - relapse - Headache intensity - rescue medication - global evaluation - presence or absence of associated symptoms (nausea, photophobia, phonophone) ;Timepoint(s) of evaluation of this end point: Exploratory endpoints: - absence of the most bothersome symptom: 2 hours post dose - relapse: 48 hours post dose - Headache intensity: predose, 0.5, 1, 1.5, 2, 4, 12, 24 and 48 hours after initial dose - rescue medication: 48 hours post-dose - global evaluation: 48 hours post dose - presence or absence of associated symptoms (nausea, photophobia, phonophone): at the time of assessment of the primary efficacy outcome (e.g. 2 hours) and at 4, 8, 12, 24- and 48-hours post-dose
