Hypersensitivity to Amylin in Post-Traumatic Headache

An interventional study of Amylin and Placebo in Headache Disorders, Secondary, Brain Diseases and Headache Disorders, sponsored by Danish Headache Center. Not yet recruiting at 1 site in Denmark. Open to participants aged 18 Years to 65 Years. Per ClinicalTrials.gov, last updated 2026-01-14.

Why
  1. The study's listed conditions name Post-Traumatic Headache, a narrower term within Headache Disorders, Secondary.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study summary

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.

In context

Post-Traumatic Headache Reclassified

192 studies on the registry are indexed under Post-Traumatic Headache; 54 are open to participants now.

This study's planned enrollment of 21 is below the median of 44 across 169 interventional studies indexed under Post-Traumatic Headache.

Lead sponsor

Danish Headache Center is the lead sponsor of 129 studies on the registry; 15 are open to participants now.

Compared within Post-Traumatic Headache, this study's primary condition as ClinicalTrials.gg classifies it; the registry's first condition term is Headache Disorders, Secondary. The counts are of registry records indexed under each term, refreshed daily. How we classify →

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

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 prior to initiation of any study-specific activities/procedures

Exclusion criteria

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 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 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 migraine-like headache or self-reported baseline headache that mimics the subjects' usual migraine-like headache
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.
