A Study to Learn About the Study Medicine Called Rimegepant in Adolescents With Frequent Migraine

United States, Canada, China200 participantsStarted 2024-11-15

Plain-language summary

The purpose of this study is to learn about the effect of a study medicine called rimegepant in adolescents who have frequent migraine attacks. Rimegepant is a tablet that dissolves when you put it on or under your tongue. The study will enroll participants who have headache for 15 days (or more) every month, of which 8 days (or more) of migraine every month, and each untreated attack lasts for an average of 4-72 hours In the 1st part of the study approximately half of the participants will receive a rimegepant tablet every other day, and approximately half of the participants will receive an inactive oral tablet (that looks the same as the rimegepant tablet) every other day. Participant experiences when they are taking the study medicine will be compared to when they are taking the inactive tablet. This will help to determine if the study medicine is safe and effective. The 1st phase of the study will last 3 months. In the 2nd part of the study all the participants who stay on study will receive rimegepant tablet every other day. This 2nd phase of the study will last 1 year. This will help determine if the study medicine is safe when taken for a long period. Those who will participate in both phases will have up to 19 visits at the study clinic, about one every 4 weeks (this may vary from 2 to 8 weeks interval during the study). Home health visits may occur as well. A health check and blood sample will be conducted at all visits. Participants will have to complete a daily diary to record the migraine attacks.

Questions worth asking your doctor

Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.

1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?

Questions for the trial coordinator

The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.

1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?

A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
