Migraine is a condition that often causes moderate to severe headaches on one side of the head, sometimes with throbbing pain, nausea, vomiting, and sensitivity to light and sound. This study evaluates the safety and effectiveness of atogepant, a medicine approved for preventing migraines in adults, to see how well it works compared to placebo in preventing chronic migraines in participants aged 12 to 17 years. The study is a phase 3, double-blind trial where neither the participants nor the doctors know who receives the medicine or placebo. Participants will be randomly assigned to receive either oral atogepant tablets or placebo tablets once daily for 12 weeks. Following the treatment period, there will be a 4-week follow-up phase. The study involves about 420 participants at approximately 70 sites worldwide. Throughout the study, participants will visit hospitals or clinics regularly to complete daily diaries, undergo medical assessments and blood tests, report any side effects, and complete questionnaires. Researchers will measure the number of participants experiencing adverse events and track changes in the average monthly number of migraine days from the start of the study through week 12.

Researchers are evaluating the effects of a medicine called rimegepant in adolescents aged 12 to less than 18 years who have frequent migraine attacks. Participants must have a history of migraine for at least 6 months, experience 15 or more headache days per month including 8 or more migraine days, and untreated migraine attacks lasting 4 to 72 hours. This Phase 3 study aims to assess the safety and effectiveness of rimegepant for migraine prevention in this age group. In the first part of the study, about half of the participants will receive a rimegepant tablet every other day, and the other half will receive a matching placebo tablet every other day. This phase will last for 3 months and is double-blind and placebo-controlled. In the second part, all participants who continue will receive rimegepant every other day for 1 year to evaluate long-term safety. Tablets are orally disintegrating and taken on or under the tongue. Participants will have up to 19 visits at the study clinic, approximately every 4 weeks, with some visits possibly occurring every 2 to 8 weeks. Home health visits may also take place. Each visit includes a health check and blood sample collection. Participants will complete a daily diary to record their migraine attacks. The main outcome measured is the number of migraine days per month over 12 weeks.

This research aims to evaluate how well and how safely rimegepant works when taken during the peri-menstrual period to prevent menstrual migraine attacks in women with this condition. The study focuses on women aged 18 to 45 who have a history of menstrual migraines and regular menstrual cycles. It is a Phase 3 clinical trial comparing rimegepant to a placebo. Participants will receive either rimegepant 75 mg oral disintegrating tablets or matching placebo tablets for 7 days during the peri-menstrual period. In addition, they may use rimegepant or standard care medications as needed for acute migraine treatment. The study is double-blind and parallel group, meaning neither participants nor researchers know who receives the active drug or placebo during the treatment phase. During the study, researchers will monitor the average change from baseline in the number of migraine days occurring per 5-day peri-menstrual period over five menstrual cycles. Participants will be assessed regularly to track migraine frequency, safety, and medication use. The total study duration covers multiple menstrual cycles to observe effects over time and ensure participant safety.

This research aims to evaluate the effectiveness, safety, and tolerability of atogepant, a medicine approved for preventing migraine, when used to treat migraine attacks quickly. The study focuses on adults aged 18 to 75 years who have a history of moderate to severe migraine attacks. It includes a double-blind phase where neither participants nor doctors know who receives atogepant or placebo, followed by an open-label phase where everyone receives atogepant. The study is conducted at about 160 sites worldwide with around 1300 participants. Participants will receive both atogepant and placebo in a random sequence to treat qualifying migraine attacks during the double-blind phase. After treating four migraine attacks this way, participants will enter an open-label phase lasting until week 24, during which they will receive atogepant for any additional migraine attacks. Treatments are given as oral tablets. Throughout the study, participants will attend regular hospital or clinic visits and telephone check-ins. They will complete electronic diaries with questionnaires about their migraines and treatment effects. Medical assessments, blood tests, and monitoring for side effects will be conducted. The main outcome measured is the percentage of participants who experience freedom from pain two hours after taking the study medication for their first treated migraine attack, observed over about 16 weeks.
