Migraine, Acute
Conditions
Brief summary
This Clinical Trial evaluates the Safety and Efficacy of Rizatriptan for the Acute Treatment of Migraine in Children and Adolescents.
Interventions
For participants randomized to placebo in Stage 1: a single placebo ODT was to be taken within 30 minutes of onset of qualifying migraine.
For participants randomized to rizatriptan in Stage 1: a single 5 or 10 mg rizatriptan orally disintegrating tablet (ODT) was to be taken within 30 minutes of onset of qualifying migraine (defined as a migraine of moderate or severe intensity). Rizatriptan dose administered was based on participant weight at Screening: those \<40 kg received 5 mg tablet, those ≥40 kg received 10 mg tablet.

| Pain Freedom at 2 Hours Post Dose in Participants Between 12 and 17 Years of Age | 2 hours post Stage 2 dose | Pain intensity was assessed using a 5-Face Pain Scale ranging from 1=no pain to 5=very bad pain. Pain freedom was defined as a reduction in severity from a rating of 3, 4 or 5 (moderate or severe pain) at the Stage 2 baseline (15 minutes post Stage 1 dose) to a rating of 1 (no pain) at 2 hours post Stage 2 dose. Missing data were imputed by carrying forward the preceding Stage 2 pain intensity values. Missing Stage 2 baseline values were imputed by carrying forward the Stage 1 baseline value, if available. |

Participant flow
Pre-assignment details
Participants randomized to double-blind study medication (Stage 1 - placebo or rizatriptan in a 20:1 ratio) at the Screening visit were given study drug and administration instructions. If a participant had not treated a qualifying migraine attack within up to 2-4 months, he/she may have been discontinued from the study

Pain Freedom at 2 Hours Post Dose in Participants Between 12 and 17 Years of Age
Pain intensity was assessed using a 5-Face Pain Scale ranging from 1=no pain to 5=very bad pain. Pain freedom was defined as a reduction in severity from a rating of 3, 4 or 5 (moderate or severe pain) at the Stage 2 baseline (15 minutes post Stage 1 dose) to a rating of 1 (no pain) at 2 hours post Stage 2 dose.

Time frame: 2 hours post Stage 2 dose
Population: Includes participants who did not respond to placebo in Stage 1, were randomized to and took Stage 2 study drug and had both Stage 2 baseline migraine severity (moderate or severe) and at least one post Stage 2 dose efficacy measurement prior to or including the 2 hour post dose time point.
