Summary

The purpose of this study is to learn about the effects of Rimegepant to help prevent migraine.

This study is seeking for participants who:

* Are male and female of 18 years of age or older.
* Have at least 1 year history of migraine .
* Did not take any medication for migraine before the start of this study. The study will go on for around 30 weeks, including 4 Phases and 11 Visits. Participants who are selected for the study will be randomly assigned to treatment groups. After which, the participants will enter a 12-week Double-blind Treatment (DBT) Phase. After finishing the DBT Phase, some selected participants may enter a 12-week Open-label Extension (OLE) Phase. Participants will come back to the study site at the end of Week 24 for the End of Treatment (EOT) Visit. There will be a follow-up Week 2 Visit around 14 days after the EOT visit.

Participants will be asked to take 1 tablet of study medicine every other calendar day. This need to be followed regardless of whether they have a migraine on that day or not. During the OLE Phase only, if a participant has a migraine on a non-scheduled dosing day, they may take 1 tablet of Rimegepant orally disintegrating tablet (ODT) as acute treatment for their migraine, if needed, with a maximum of 1 tablet of Rimegepant per calendar day. The study team will look at how each participant is doing with the study treatment during the regular visits at the study clinic.
