Does adrenomedullin trigger migraine-like headaches in people with persistent post-traumatic headache?

Official title: Hypersensitivity to Adrenomedullin in Post- Traumatic Headache: A Randomized Clinical Trial

Run by Danish Headache Center · NCT07059546 · Data updated 2026-11-12

This trial will test if a short intravenous infusion of the neuropeptide adrenomedullin can trigger migraine-like headaches in adults with long-standing post-traumatic headache after a single mild head injury.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults 18–65 with a single mild traumatic brain injury, persistent post-traumatic headache for ≥12 months, and an average of at least 4 headache days per month, who can safely undergo an IV infusion and monitoring.

Probably not a fit

Patients with multiple head injuries, moderate or severe TBI, pre-existing primary headache disorders (other than infrequent tension-type headache), whiplash, prior craniotomy, or other significant comorbid conditions are unlikely to benefit or be eligible.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

The trial uses a randomized, double-blind, placebo-controlled, two-way crossover design in which participants receive an intravenous infusion of adrenomedullin on one visit and placebo on another. Adults aged 18–65 with persistent post-traumatic headache for at least 12 months and an average of ≥4 headache days per month are eligible, provided they had a single mild traumatic brain injury and no prior primary headache disorder. Investigators will record whether the infusion provokes headache with migraine-like features and monitor vital signs and adverse events throughout each visit. The crossover design allows each participant to serve as their own control, improving sensitivity to detect a provocation effect.

Why it matters

Potential benefit: If successful, the study could clarify a biological trigger for post-traumatic migraine-like headaches and point toward new targeted treatments or preventive strategies.

How similar studies have gone: Provocation studies with other neuropeptides (for example, CGRP and PACAP) have induced migraine-like attacks in susceptible people, but adrenomedullin provocation is a relatively novel approach with limited prior data.

Inclusion Criteria:

* Age 18 to 65 years of age upon entry into screening
* History of persistent headache attributed to mild traumatic injury to the head for ≥ 12 months and in accordance with the International Classification of Headache Disorders, 3rd Edition (ICHD-3)
* ≥ 4 monthly headache days on average across the 3 months prior to screening
* Provision of informed consent prior to initiation of any study-specific activities/procedures.

Exclusion Criteria:

* \> 1 mild traumatic injury to the head
* History of any primary or secondary headache disorder prior to mild traumatic injury to the head (except for infrequent episodic tension-type headache)
* History of moderate or severe injury to the head
* History of whiplash injury
* History of craniotomy
* History or evidence of any other clinically significant disorder, condition or disease (except for those outlined above) than, 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
* Cardiovascular disease of any kind, including cerebrovascular diseases
* Hypertension (systolic blood pressure of ≥150 mmHg and/or diastolic blood pressure of ≥100 mmHg) prior to the start of infusion on the experimental day
* Hypotension (systolic blood pressure of ≤90 mmHg and/or diastolic blood pressure of ≤50 mmHg)
* Initiation, discontinuation, or change of dosing of prophylactic medications within 2 months prior to study inclusion
* Intake of acute medications (e.g. analgesics, triptans) within 48 hours of infusion start
* Baseline headache intensity of \>3 on an 11-point numeric rating scale (0 being no headache, 10 being the worst imaginable headache)
* Baseline headache with migraine-like features or self-reported baseline headache that mimics the subjects' usual headache with migraine-like features
