Placebo to rizatriptan 10 mg ODT orally for a moderate or severe migraine attack

Level of functional disability was assessed on a paper diary by the participants. Level of functional disability was rated as: normal, mildly impaired, severely impaired, or unable to do activities, requires bedrest. Functional disability ratings was dichotomized to Normal and Not Normal (mildly impaired, severely impaired, or unable to do activities, requires bedrest) for analysis.

Patient satisfaction was assessed on a paper diary by the participants. Level of satisfaction was rated as: completely satisfied, very satisfied, somewhat satisfied, neither satisfied nor dissatisfied, somewhat dissatisfied, very dissatisfied, or completely dissatisfied. The overall 24-hour assessment of study medication was dichotomized to Satisfaction (completely satisfied, very satisfied, somewhat satisfied) and Non-satisfaction (neither satisfied nor dissatisfied, somewhat dissatisfied, very dissatisfied, or completely dissatisfied) for analysis.

First migraine treated with Placebo; second migraine treated with Rizatriptan 10 mg Orally Disintegrating Tablet (ODT); third migraine treated with Rizatriptan 10 mg Orally Disintegrating Tablet (ODT)

Total of all reporting groups

Placebo. Patients who treated one attack, that was intended to be treated with placebo, were included. One patient who treated an attack with placebo within 48 hours of the previous attack was excluded from the placebo group.

24-hour sustained pain relief (defined as pain relief at 2 hours post dose, with no administration of any rescue medication and with no occurrence of a moderate/severe headache during the respective period after dosing with the blinded study medication.

Full Analysis Set, which included all randomized participants who had at least one evaluable attack. To be considered an evaluable attack, the attack must have met the FAS criteria for PR at 2 hours post-dose, and from 2-24 hours the participant either answered 24-hour headache recurrence question or didn't have PR at any time or took rescue.

Headache pain severity, relative to the administration of study medication, was rated by the participants in a paper diary. Pain severity rating scale: 0 (no pain), 1 (mild pain), 2 (moderate pain), or 3 (severe pain). Pain freedom (PF) is defined as a reduction in headache severity from Grade 3/2 at baseline to Grade 0 (no pain) post dose.

Full Analysis Set, which included all randomized participants who had at least one evaluable attack. To be considered an evaluable attack, the participant must have administered study treatment for this attack and have both a baseline severity measurement and at least one post-dose efficacy measurement at or prior to the 2-hour time point.

Level of functional disability was assessed on a paper diary by the participants. Level of functional disability was rated as: normal, mildly impaired, severely impaired, or unable to do activities, requires bedrest.

Patient satisfaction was assessed on a paper diary by the participants. Level of satisfaction was rated as: completely satisfied, very satisfied, somewhat satisfied, neither satisfied nor dissatisfied, somewhat dissatisfied, very dissatisfied, or completely dissatisfied. The overall 24-hour assessment of study medication was dichotomized to Satisfaction (completely satisfied, very satisfied, somewhat satisfied) and Non-satisfaction (neither satisfied nor dissatisfied, somewhat dissatisfied, very dissatisfied, or completely dissatisfied) for analysis.

Full Analysis Set, which included all randomized participants who had at least one evaluable attack. To be considered an evaluable attack, the participant must have administered study treatment for this attack and have both a baseline severity measurement and post-dose satisfaction measurement at the 24-hour time point.

Placebo. Patients who treated an attack with placebo were included. Adverse events occurring within 14 days of administration of placebo, but not within 14 days of any administration of rizatriptan (including sponsor-provided rescue), were attributed to placebo group.

It is possible for one patient to be counted twice (once in each treatment group).

The number of randomized patients is 108, out of which, 101 took at least one dose of rizatriptan (including sponsor-provided rescue), and 94 took placebo.
