About this trial
Acute treatments for migraine may not provide sufficient pain relief after an initial dose, and a second dose of a given medication may be needed to fully abort an attack. International Headache Society (IHS) global practice recommendations for the Acute Treatment of Migraine suggest a second dose of the same medication within the recommended dose limit in people with headache relapse after successful initial treatment of a migraine attack.
The primary purpose of this study is to evaluate the safety and tolerability of redosing of rimegepant when taken for the acute treatment of a migraine attack, as it is possible that some patients may benefit from a second dose of rimegepant in this setting.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Eligible participants include adult participants aged 18 years of age or older with a minimum 1-year history of migraine (with or without aura) consistent with International Classification of Headache Disorders, 3rd Edition
Eligible participants must be currently using acute migraine treatment in accordance with the local label and have all of the following on average across the 12 weeks prior to the Screening Visit and, during the first 28 days of the observation phase (OP): (1) 6-14 monthly migraine days (MMDs); (2) <15 monthly headache days (MHDs) (migraine or non-migraine); and (3) <7 monthly non-migraine headache days.
Participants with headaches occurring ≥15 days per month (migraine or non-migraine) on average across the 12 weeks prior to the Screening Visit and ≥7 non-migraine headache days per month on average across the 12 weeks prior to the Screening Visit would not be eligible.

Trial outcomes
Primary outcomes
Incidence of Treatment-Emergent Adverse Events (TEAEs), serious TEAEs, and TEAEs leading to study intervention discontinuation on treatment by average monthly redosing frequency over the entire OLT phase (<3, ≥3 to <6, ≥6 re-doses per month) and overall
Incidence of LFT elevations, AST >3x ULN, alanine aminotransferase ALT >3x ULN, and total bilirubin >2x ULN on treatment by average monthly redosing frequency over the entire OLT phase (<3, ≥3 to <6, ≥6 re-doses per month) and overall
Secondary outcomes
Percentage of rimegepant-redosed headache days with satisfaction with headache pain reduction over the entire OLT phase, based on a rating of 'Extremely satisfied' or 'Satisfied' for satisfaction with study intervention to reduce headache pain
Percentage of rimegepant-redosed headache days with reduced impact on daily activities over the entire OLT phase, based on a rating of 'Very good' or 'Good' for the ability of study intervention to reduce the impact of headaches on daily activities
