This study is about testing a new medicine called **rimegepant** to see if it helps prevent **migraine** headaches in kids and teens. Migraine is a type of headache that can make you feel really bad, and sometimes you see flashes of light or feel sick to your stomach. **Placebo** is a pretend medicine that doesn’t do anything. In this study, some kids will get rimegepant, and some will get a placebo to compare how they work.

To join the study, you must have had migraines for at least 6 months and be between 6 and 17 years old. You should have a certain number of headache days each month and be able to tell apart different types of headaches. You also need to be a certain weight, and if you’re already taking medicine to prevent migraines, you must stay on the same dose.

• The study lasts several months and includes multiple visits.
• Participants may receive compensation for their time and effort.
• It’s important to consider the potential risks and side effects of the treatment.
