About this study
Official title: Hypersensitivity to Amylin in Post-Traumatic Headache: A Randomized Clinical Trial
Pramlintide is a peptide analogue of human amylin which is a vasoactive substance involved in the pathogenesis of headache. This study investigates whether pramlintide induces migraine-like headache in people with persistent post-traumatic headache (PTH) attributed to mild traumatic brain injury (mTBI).
Read the detailed description
Amylin is a vasodilator released from nerve fibers within the trigeminovascular system, which is considered a key anatomical and physiological substrate in the pathogenesis of migraine and persistent post-traumatic headache (PTH). Persistent PTH attributed to mild traumatic brain injury frequently presents with migraine attacks, suggesting shared underlying mechanisms with migraine. This study aims to determine whether intravenous infusion of pramlintide, an analogue of amylin, can induce migraine-like headache in individuals with persistent post-traumatic headache. To test this hypothesis, we will conduct a randomized, double-blind, placebo-controlled, two-way crossover study.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
AmylinDrug
The participants will receive continuous intravenous infusion of 6 μg/min of pramlintide (amylin) over 20 minutes.
PlaceboDrug
The participants will receive continuous intravenous infusion of 20 mL of placebo (isotonic saline) over 20 minutes.
| Study group | Role | What they receive |
|---|---|---|
| Amylin | Experimental | Pramlintide (Amylin) will be administered by intravenous infusion. Receives: Drug: Amylin |
| Placebo | Placebo comparator | Placebo (isotonic saline) will be administered by intravenous infusion. Receives: Drug: Placebo |

Questions about this trial
What is this clinical trial studying?
A study testing Amylin in people with Headache Disorders, Secondary and Brain Diseases, run by Danish Headache Center at 1 site in Denmark.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 4 inclusion and 15 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 14 Jan 2026. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Haidar Al-Khazali, MD, PhD (+4541598494, haidardk@hotmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Incidence of migraine-like headache (time frame: 12 hours). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT07340775, which also lists 7 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 14 Jan 2026.
