E.2 Objective of the trial

E.2.1

Main objective of the trial

To compare the efficacy of rimegepant to placebo as a preventive treatment for migraine in adolescents (≥ 12 to <18 years of age) with episodic migraine, as measured by the reduction from baseline in the mean number of migraine days per month over the entire course of the double-blind treatment phase.

E.2.2

Secondary objectives of the trial

● To compare the efficacy of rimegepant to placebo on the proportion of subjects that have at least a 50% reduction from baseline in the mean number of moderate to severe migraine days per month over the entire course of the double-blind treatment phase in adolescents with episodic migraine.
● To compare the efficacy of rimegepant to placebo on the reduction from baseline in the mean number of migraine days per month in the first 4 weeks of the double-blind treatment phase in adolescents with episodic migraine.
● To compare the change from baseline in the Pediatric Quality of Life (PedsQLTM) 4.0 Generic Core Scales total score at Week 12 of the double-blind treatment phase between rimegepant and placebo in adolescents with episodic migraine.

E.2.3

Trial contains a sub-study

E.3

b. 6 or more migraine days during the Observation Period
c. 14 or less headache days during the Observation Period
d. Pediatric Migraine Disability Assessment Scale (PedMIDAS) Disability Score of >10 to ≤50, indicating mild (score of 11 to 30) or moderate (score of 31 to 50) disruption in daily activities, as assessed at the Baseline (Randomization) Visit
