Eptinezumab as an Adjunct to Standard of Care for Migraine in an Acute Emergency Context

The purpose of the study is to investigate how a medication called eptinezumab (Vyepti) given to patients in the Emergency Department (ED) might help prevent migraines from happening again. The results of this study may help inform better ways to manage patients with migraines in the ED. Eptinezumab is currently approved by Health Canada for the preventive treatment of migraine, but its short-term effectiveness in the ED context is unknown. Unlike other migraine treatments used in the ED, eptinezumab can rapidly interrupt the migraine process, potentially also preventing migraine from coming back in the short term. Most patients with a diagnosis of migraine have no access to preventative therapies. This study will be able to provide access to preventative therapy at the earliest stages of a migraine attack. Administering this medication in the ED may stop the attack more effectively compared to current therapies. This study wants to see if eptinezumab could help stop migraines from coming back after individuals have been treated in the ED. The study will also explore whether eptinezumab could reduce how often individuals with migraine might need to come back to the ED, what other medications they might need alongside eptinezumab, and how they feel overall.
