Brief Title
Efficacy and Tolerability of Rimegepant for the Acute Treatment of Migraine in Adults Unsuitable for Triptan Use
Detailed Description
This study is being conducted to evaluate the efficacy and tolerability of rimegepant in a population of adults that are unsuitable for triptan medications due to a previous intolerance, lack of efficacy, or contraindication (including a history of clinically-relevant cardiovascular disease). Rimegepant will be further evaluated in this population with as needed use in a 12-week, open-label extension study.

Outcome Description
An AE was defined as any new untoward medical occurrence or worsening of a pre-existing medical condition in a participants or clinical investigation participant administered an investigational (medicinal) product and that does not necessarily have a causal relationship with the treatment. AE intensity included mild, moderate and severe. Mild AE was defined as AEs which is usually transient and required only minimal treatment or therapeutic intervention. The event did not generally interfere with usual activities of daily living. Moderate AE was defined as AEs which was usually alleviated with additional specific therapeutic intervention. The event interfered with usual activities of daily living, causing discomfort but poses no significant or permanent risk of harm to the participants. Severe AE was defined as AE that interrupted with usual activities of daily living, significantly affected clinical status, or required intensive therapeutic intervention.

Outcome Description
MIBS was a 4-item self-administered questionnaire that measured interictal migraine related burden in the past 4 weeks on days when participants were not having an attack, using 4 domains: impairment in work or school; impairment in family and social life; difficulty making plans or commitments; emotional/affective and cognitive distress. The questionnaire specifically asked about the effect of the disease over the past 4 weeks on days without a headache attack. Response options included: don't know/not applicable (0), never (0), rarely (1), some of the time (2), much of the time (3), or most or all of the time (3). Each response associated with numerical score were summed across all 4 items resulting in a total MIBS score ranging from 0 to 12, and the level of interictal burden being categorized into the following: 0 for none and 12 for severe. Higher scores indicate worse interictal burden.
