Treatment: Drugs - Rimegepant
Treatment: Drugs - Placebo
Treatment: Drugs - Rimegepant

Experimental: Rimegepant - Rimegepant - Double-blind (DB) Phase: One dose of rimegepant 75 mg Oral Disintegrating Tablet (ODT)

Rimegepant/Rimegepant - Open-label Extension (OLE) Phase: participants receive one dose rimegepant 75 mg ODT as needed for a qualifying acute migraine. A qualifying migraine is an attack of moderate or severe headache pain intensity. Migraine headache pain intensity will be measured on a 4-point numeric rating scale (0=none, 1=mild, 2=moderate, 3=severe)

Placebo comparator: Placebo - Placebo - Double-blind (DB) Phase: One dose of matching placebo

Placebo/Rimegepant - Open-label Extension (OLE) Phase: participants receive one dose rimegepant 75 mg ODT for a qualifying migraine


Treatment: Drugs: Rimegepant
DB Phase: Rimegepant 75 mg Orally Disintegrating Tablet (ODT)

Treatment: Drugs: Placebo
DB Phase: matching placebo

Treatment: Drugs: Rimegepant
OLE Phase: Rimegepant 75 mg ODT in association with each of the first 5 qualifying migraines

Outcomes
Primary outcome [1] 0 0
Compare the efficacy of rimegepant with placebo in the acute treatment of migraine, as measured by migraine headache pain relief at 2-hours post-dose during the Double-Blind Treatment (DBT) Phase.
Timepoint [1] 0 0
2 hours post-dose

Eligibility
Key inclusion criteria
* Migraine attacks present for more than 1 year with the age of onset prior to 50 years of age.
* Migraine attacks, on average, lasting about 4 - 72 hours if untreated.
* 4 to 14 migraine days per month on average across the 3 months prior to the Screening Visit (month is defined as 28 days for the purpose of this protocol).
* Less than 15 headache days (migraine or non-migraine) per month in each of the 3 months prior to the Screening Visit and throughout the Screening Phase.
* Subjects must be able to distinguish migraine attacks from tension/cluster headaches.
* Subjects on prophylactic migraine medication (excluding CGRP antagonists) are permitted to remain on therapy if they have been on a stable dose for at least 3 months (12 weeks) prior to the Screening Visit, and if the dose is not expected to change during the course of the study.
* Triptan unsuitable
