About this study
Official title: CORRELATE-UK: COnsistency of Response With RimegEpant Oral Lyophilisate in Acute Treatment of migrainE in the United Kingdom
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.
Read the detailed 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Time to Meaninful Pain Relief (MPR) post-dosing
Proportion of rimegepant-treated attacks with reported MPR: within 1 hour post dose; 1-2 hours post dose; Over 2 hours up to 4 hours post dose; More than 4 hours post dose; who have not achieved MPR and took the medication more than 2 hours before completing the survey; who have not achieved MPR and took the medication less than 2 hours before completing the survey
Measured: Daily (within 24hs post dose)
Secondary outcomes (3)
Time to improvement in non-pain symptoms post-dosing
Proportion of rimegepant-treated attacks with reported improvement in any non-pain symptoms: within 1 hour post dose; 1-2 hours post dose; Over 2 hours up to 4 hours post dose; More than 4 hours post dose; who have not had a meaninful improvement and took the medication more than 2 hours before completing the survey; who have not had a meaninful improvement and took the medication less than 2 hours before completing the survey.
Measured: Daily (within 24hs post dose)
Acute migraine treatment optmization
Proportion of participants who reported treatment optimization using mTOQ6 questionnaire. Treatment optimization is categorized into: very poor treatment optimization, poor treatment optimization, moderate treatment optimization, maximum treatment optimization
Measured: 12 weeks follow up
Acute migraine treatment optmization
Treatment satisfaction assessed using TSQM-II questionnaire. Domain scores (0-100) is presented for the following domains: effectiveness, Side effects, Convenience, and global satisfaction. Higher scores indicate greater satisfaction. Scores are reported separately for each domain.
Measured: 12 weeks follow up
