Japan524 participantsStarted 2023-07-12

Plain-language summary

A migraine is a moderate to severe headache on one side of the head. A migraine attack is a headache that may be accompanied by throbbing, nausea, vomiting, sensitivity to light and sound, or other symptoms. This study will assess how safe and effective three different doses of atogepant is compared to placebo in adult Japanese participants. Change in migraine symptoms will be assessed. Atogepant (Qulipta) is an approved drug to treat adults with episodic migraine in the United States. Participants are randomly assigned to one of the 4 treatment groups called Arms to receive atogepant or matching placebo. There is 1 in a 4 chance for the participant to receive placebo. This is double-blinded study which means neither study doctor not the participant will know if the participant received atogepant or placebo. Approximately 520 adult participants with episodic migraine will be enrolled in approximately 50 sites across Japan. Participants will receive oral atogepant or matching placebo tablets once daily for 12 weeks. At 12 weeks participants assigned to atogepant dose A, dose B or dose C will continue to receive same treatment for 12 additional weeks and participants assigned to placebo will be re-randomized to receive atogepant dose A, dose B or dose C for 12 additional weeks. All participants will be followed for 30 days following last dose of study drug. There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The safety and tolerability of the treatment will be checked by medical assessments, blood tests, checking for adverse events and completing questionnaires.

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.
