Rimegepant
Experimental group
Description:
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)
Treatment:
Drug: Rimegepant
Placebo
Placebo Comparator group
Description:
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
