Official title
AN INTERVENTIONAL EFFICACY AND SAFETY, PHASE 3, DOUBLE-BLIND, RANDOMIZED, 2-ARM STUDY TO INVESTIGATE THE PREVENTION OF CHRONIC MIGRAINE WITH RIMEGEPANT COMPARED WITH PLACEBO IN PARTICIPANTS 18 YEARS OF AGE OR OLDER
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
Rimegepant is a calcitonin gene-related peptide (CGRP) receptor antagonist approved for the acute treatment of migraine attacks in adults and for the preventive treatment of episodic migraine in adults when administered every other day. This study evaluates once daily rimegepant for the preventive treatment of chronic migraine. After a 28-day observation period without study intervention, eligible participants will be randomized in a 1:1 ratio to receive either rimegepant 75 mg orally disintegrating tablet (ODT) or matching placebo once daily for 12 weeks under double-blind conditions. Participants who remain eligible at the end of the double-blind treatment phase will enter a 12-week open-label treatment period, during which all participants will receive open-label rimegepant 75 mg once daily. During this period, participants may also take an additional rimegepant tablet for the acute treatment of breakthrough migraine attacks, up to 10 doses per month. A 28-day follow-up period completes the approximately 32-week study. The primary objective of the study is to determine whether once-daily rimegepant is more effective than placebo in reducing monthly migraine days relative to the observation period in adults with chronic migraine. Secondary objectives include evaluating differences between rimegepant and placebo in migraine responder rates, headache severity, acute migraine medication use, quality of life, work productivity, cognitive functioning, and safety and tolerability. Approximately 400 adults aged 18 years or older with a diagnosis of chronic migraine for at least 1 year will be enrolled at multiple study sites.
