Investigating brain changes in migraine patients treated with erenumab

Registry for Migraine - Structural and Functional Magnetic Resonance Imaging Before and After Erenumab Treatment

Phase 4 Interventional Danish Headache Center · NCT04674020

This study looks at how a migraine prevention medication called erenumab affects the brain of people who have had migraines for over a year by using MRI scans before and after treatment.

What this trial studies

This study examines the structural and functional changes in the brain of migraine patients using magnetic resonance imaging (MRI) before and after treatment with erenumab, a medication designed to prevent migraines. The research focuses on individuals who have experienced migraines for at least a year and have a specific frequency of headache days. By analyzing MRI data, the study aims to provide insights into how erenumab affects the brain's structure and function in those suffering from migraines.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a history of migraines for at least 12 months and a minimum of four migraine days per month.

Not a fit: Patients who developed migraines after the age of 50 or have a history of cluster headaches or hemiplegic migraines may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of migraine treatment effects and lead to improved therapeutic strategies for patients.

How similar studies have performed: Other studies have shown promising results in understanding migraine treatments, but this specific approach using MRI with erenumab is relatively novel.

Inclusion Criteria:

* Subject has provided informed consent prior to initiation of any study-specific activities/procedures
* Age greater than or equal to 18 years upon entry into screening
* History of migraine (with or without aura) for greater than or equal to 12 months before screening according to the International Headache Society (IHS) Classification ICHD-3 (Headache Classification Committee of the International Headache Society, 2018) based on medical records and/or patient self report

Exclusion Criteria:

Subjects are excluded from the study if any of the following criteria apply:

Disease Related

* Evidence of current pregnancy or breastfeeding per subject self-report or medical records
* Subject has known sensitivity to any of the products or components to be administered during dosing
* Subject likely to not be available to complete all protocol-required study visits or procedures, and/or to comply with all required study procedures to the best of the subject and investigator's knowledge
