Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pain Relief (PR) | 2 hours post dose | Pain severity 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 relief (PR) is defined as a reduction in headache severity from Grade 3/2 at baseline to Grade 1/0 post dose. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Sustained Pain Relief (SPR) | 2 - 24 hours post dose | 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. |
| Pain Freedom (PF) | 2 hours post dose | 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. |
| Normal Rating of Functional Disability (NRFD) | 2 hours post dose | 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. |
| Treatment Satisfaction (TS) | 24 hours post dose | 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. |

Outcome results
Pain Relief (PR)
Pain severity 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 relief (PR) is defined as a reduction in headache severity from Grade 3/2 at baseline to Grade 1/0 post dose.
Time frame: 2 hours post dose
Population: 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.
| Arm | Measure | Group | Value (NUMBER) |
|---|---|---|---|
| Rizatriptan | Pain Relief (PR) | Resulting in PR at 2 hours post dose | 105 Attacks |
