Key clinical point: Rimegepant was effective and had favourable safety and tolerability profiles in the preventive treatment of migraine.
Major finding: Rimegepant was superior to placebo in terms of change in the mean number of migraine days per month during weeks 9-12 (−4.3 days vs. −3.5 days; least squares mean difference, −0.8 days; P = .0099). Adverse events were reported by 133 of the patients who received rimegepant and 133 participants in the placebo group.

The safety analysis included 741 participants, who received at least one dose of study medication.
