Acute Migraine Treatment in the ED With Gepants

Description

This study evaluates the effectiveness of rimegepant 75 mg orally disintegrating tablet (ODT) single-dose or zavegepant 10 mg nasal spray single-dose as acute migraine treatments during Emergency Department (ED) encounters. Although these two calcitonin gene-related peptide receptors (CGRP) receptor antagonists are FDA-approved for the indication of acute migraine treatment, past studies have been limited to the outpatient setting. If these medications are effective in the Emergency Department, their delivery methods alone may have advantages over intravenous medications commonly used for acute migraine in EDs, including quicker time to treatment delivery, faster pain relief, and reduced ED length of stay. This investigation is a pilot study to examine rimegepant and zavegepant in an ED, to gain insight on effectiveness in this setting. This study will administer rimegepant 75 mg ODT single-dose or zavegepant 10 mg nasal spray single-dose as acute migraine treatments to 100 patients in the Emergency Department. It is a single center, open-label, non-controlled 2-group clinical trial (allocated 1:1 to rimegepant or zavegepant via pseudo-random assignment). The study will enroll adults in the ED meeting ICHD-3 criteria for migraine or probable migraine, with or without aura.
