Comparative Effectiveness of Migraine Preventive Medications: The APT Comparison Study

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.
