Migraine is a type of headache that can be very painful and may come with feeling sick to your stomach, throwing up, and being sensitive to light and sound. This study tests a medicine called ubrogepant to see if it helps kids and teens (ages 6-17) who have migraines. Ubrogepant is already used by adults for migraines. Kids and teens will either get the actual medicine or a placebo (a pill that looks the same but has no medicine). The study will last up to 6 months and will involve around 1059 participants in the US.

• Study lasts up to 6 months with regular hospital visits.
• Participants have a 1 in 3 chance of getting a placebo.
• Participants will take medicine or placebo when they have a migraine attack.

Doctors will check how well the medicine works by asking questions, doing medical tests, and taking blood samples. There may be more visits and tests than usual care for migraines. Participants need to be able to swallow pills and fill out surveys, possibly with a parent’s help. Participants must weigh between 44 and 298 pounds and cannot have certain health problems or be on specific medications.
