About this trial
Calcitonin gene-related peptide (CGRP) is a key neuropeptide in migraine pathophysiology and treatment. This study investigates whether CGRP administration can trigger aura in individuals with a diagnosis of migraine with aura.
Eligibility criteria
This trial does not accept healthy volunteersQualifiers
Age 18 to 65 years of age upon entry into screening
History of migraine with aura for ≥ 12 months according to the International Classification of Headache Disorders 3rd Edition (ICHD-3) criteria
≥ 1 monthly day with aura that meets criteria as aura on average across the three months before screening
Provision of informed consent prior to initiation of any study-specific activities/procedures.
Disqualifiers
Any history of a primary or secondary headache disorder other than migraine without aura, migraine with aura, chronic migraine, and episodic tension-type headache
History or evidence of any other clinically significant disorder, condition, or disease (except for those outlined above) that, in the opinion of the site investigator, would pose a risk to subject safety or interfere with study evaluation, procedures or completion
The subject is at risk of self-harm or harm to others as evidenced by past suicidal behavior
Female subjects of childbearing potential with a positive pregnancy test during any study visit

Treatment groups
Trial outcomes
Primary outcomes
Incidence of migraine attacks with aura
Difference in incidence of migraine attack with aura between CGRP and placebo during the 12-hour observational period after infusion start.
Secondary outcomes
Incidence of migraine attacks without aura
Difference in incidence of migraine headache between CGRP and placebo during the 12-hour observational period after infusion start.
Headache intensity scores
Difference in area under the curve (AUC) for headache intensity scores between CGRP and placebo during the 12-hour observational period after infusion start.
