• Subject has provided informed consent prior to initiation of any study-specific activities/procedures.

• Must have demonstrated greater than or equal to 75% compliance in Headache Diary usage during the 4-week run-period prior to Day 1 of the open-label treatment phase.

Exclusion Criteria:

• Previously received erenumab (Aimovig)

• Received anti-CGRP monoclonal antibody within 3 months prior to the CGRP-infusion

• Currently receiving treatment in another investigational device or drug study, or less than 30 days or 5 half-lives since ending treatment on another investigational device or drug study(ies). Other investigational procedures while participating in this study are excluded.

• Hypotension on the experimental day defined as systolic blood pressure < 90mmHg or diastolic blood pressure < 50mmHg

• Any headache (including migraine) within 24 hours prior to the start of the CGRP-infusion

• Intake of any analgesics or migraine-specific medications within 24 hours prior to the start of the CGRP-infusion

• Subject likely to not be available to complete all protocol-required study visits or procedures, and/or comply with all required study procedures to the best of the subject and study investigator's knowledge
