Novel Insight Into Migraine Pathophysiolgy and Galcanezumab Mechanisms of Action

• Status: Recruiting
• Trial end date: 2022-03-31
• Target enrollment: 0
• Participant gender: All

Summary

The purpose of this study is to understand better the mechanisms of action of calcitonin gene related peptide (CGRP) targeted monoclonal antibodies in migraine prevention. Specifically, the protocol will allow the investigators to determine whether the main site of action of this novel and recently-approved class of migraine prophylactic drugs act inside or outside the brain and if so, where.

• Phase: Phase 4
• Accepts Healthy Volunteers?: No

• Participating in any other therapeutic clinical investigation or has participated in a clinical trial in the preceding 30 days

• Belongs to a vulnerable population or has any condition such that his or her ability to provide informed consent, comply with the follow-up requirements, or provide self-assessments is compromised.

• A relative of or an employee of the Investigator or the clinical study site
