Eary Infusion of Eptinezumab for TreatmEnt of ACute Post-Traumatic Headaches (ELITE-ACT)

Sponsor: Sunnybrook Health Sciences Centre

Summary

Most individuals with mild traumatic brain injury (mTBI) experience post-traumatic headaches (PTH). Of PTH, 50% present with a migraine phenotype which is the most disabling type of PTH. Patients with migraine-PTH are at greater risk of persistent symptoms whereby the acute PTH (aPTH) becomes persistent PTH (pPTH) (ie. lasting \> 3 months) with a conversion rate of 47-95%. As migraine symptoms become chronic, it becomes treatment resistant. Despite these implications, early preventive medication management of PTH is marred by lengthy trials of multiple medications (2-3 months for each) and adverse effects that aggravate mTBI symptoms (fatigue, nausea, and presyncope). There is a compelling need to establish an effective treatment to prevent this debilitating outcome. Eptinezumab is a calcitonin gene-related peptide (CGRP)-blocking monoclonal antibody that reduces migraine burden in patients with migraines after a single infusion. Patients with PTH have higher serum levels of CGRP and experimental infusion of CGRP to patients with mTBI reproduces migraine PTH symptoms. Given the similarly in CGRP expression between chronic migraines and PTH, an infusion of eptinezumab within 8 weeks of PTH is hypothesized to reduce headache burden 3 months after treatment and prevent pPTH.
