About

This is a non-interventional, prospective study that will enroll participants with migraine in the United Kingdom currently in use of rimegepant to acutely treat migraine attacks. Participants will be followed up for up to 12 weeks and will complete a daily questionnaire to self-report the consistency of response to rimegepant in acute treatment of migraine.

Full description

This is a prospective observational, real-world cohort study of the patient-reported consistency of response to rimegepant in acute treatment of migraine. Longitudinal data capture will allow the determination of treatment effectiveness across multiple attacks, while the observational design will ensure the data reflect a real-world setting. In addition, a patient-centered real-time approach will allow for capture of granular data and will minimize patient recall bias, which is important for subjective outcomes such as pain. Patient reported outcome measures will be collected at study enrolment, daily during the 12-week observation period, and at the end of the study period.

The study will be conducted in the United Kingdom (UK). Potential participants will be identified and selected from UK healthcare institutions. Both patients diagnosed with episodic and chronic migraine will be included, with a split of approximately 50% of each group. Participants will be enrolled into the study over a period of approximately 6 months. The total data collection period will be approximately 9 months. Potentially eligible patients will receive briefing materials during a routine in-person consultation, or via email. Interested patients will use a link and a unique ID and PIN to complete a study eligibility screener within the study web application. The screener will consist of a series of demographic and clinical history questions. Participants who successfully complete the eligibility will then be able to proceed to the consent stage. Informed consent will also be provided within the study web application.

Consented participants will be required to complete a series of baseline demographic and clinical questions within a window of 72h from registration. A completion reminder will be sent every 24h until the completion window closes. Each participant will be followed up for 12 weeks. During this period, participants will receive an SMS with a link to the study website at the same time every day. A single click on the phone will take participants to the daily migraine survey. Two custom questions asking about migraine symptom occurrence and rimegepant use in the previous 24h will be presented to every participant daily from Day 1 to Day 84. A series of custom follow-up questions, asking further information about any migraine symptoms and related treatment, will be presented based on participant responses to questions 1 and 2 . A completion window of four days (96h) will be allowed for the daily questions. In case participants are still experiencing some migraine symptoms when prompted, they will be able to save their responses and return at a later time within the completion window. On Days 0, 28, 56 and 84 of follow-up, a menstruation question will be presented to all participants. At the end of the 12-week follow-up, the mTOQ-6 Likert version and the TSQM-II questionnaire will be presented to all participants.
