Overview
This goal of this study is to compare three medications used for migraine preventive treatment.
This study will compare atogepant, a newer migraine preventive medication, with two older preventive medications, topiramate and propranolol. It will be determined if one works better and is more tolerable than the others.
Research participants will:
- Be randomly assigned to one of the three medications.
- Provide information about their migraine pattern using a daily headache diary and during research visits.
Description
This is a prospective, randomized, comparative effectiveness clinical trial of atogepant, propranolol, and topiramate for the prevention of migraine in adults.
Eligible participants will provide information in a daily headache diary for four weeks. If after those four weeks they are still eligible for the study, they will be randomized to one of the study medications and receive study medication for twelve weeks.
Research visits occur at baseline, four weeks later for the randomization visit, and then at post-randomization weeks four, eight, twelve, twenty-four, and forty-eight.
Participants provide data using a headache diary (first 16 weeks of the study) and during research visits.
The primary endpoint is the proportion of participants in each treatment group who are "treatment responders" defined as completing the first twelve weeks of the study on the assigned medication and having a 50% or greater reduction in moderate severe headache days during weeks 9-12 post-randomization compared to the four weeks pre-randomization.
Eligibility
Inclusion Criteria:

- At least four "moderate to severe headache days" per month (by patient self-report and then confirmed during four-week pre-randomization headache diary phase) A "moderate to severe headache day" is defined as a day during which there is a headache of moderate to severe intensity that lasts for at least four hours, or a day on which a migraine-specific acute medication is taken to treat headache.
