Amylin-Induced Migraine Attacks Without Aura

January 5, 2026 updated by: Håkan Ashina, Danish Headache Center

Amylin-Induced Migraine Attacks Without Aura: A Randomized Clinical Trial

Pramlintide is a peptide analogue of human amylin which is a vasoactive signaling molecule involved in the pathogenesis of migraine. This study investigates whether pramlintide induces migraine attacks without aura in people with migraine without aura.

Study Overview

Detailed Description

Amylin is a vasoactive substance that acts on vascular smooth muscle and can cause vasodilation. It is naturally present in the trigeminovascular system, an important structure involved in headache development. Recent studies indicate that intravenous infusion of pramlintide, an amylin analogue, can trigger migraine attacks in people with migraine. This study aims to determine whether intravenous pramlintide can induce migraine attacks without aura in individuals who experience migraine without aura. To test this, the investigators will conduct a randomized, double-blind, placebo-controlled, two-way crossover trial.

Description

Inclusion Criteria:

  • Age 18 to 65 years of age upon entry into screening
  • A body weight of 50 to 100 kg
  • History of migraine without aura for ≥12 months and in accordance with ICHD-3

  • Hypotension (systolic blood pressure of ≤90 mmHg and/or diastolic blood pressure of ≤50 mmHg)
  • Abnormalities on the electrocardiogram that, in the opinion of the site investigator, might pose a risk to the subject or impact the validity of the study results

  • Headache of any intensity within 48 hours of infusion start
  • Migraine attack within 48 hours of infusion start
  • Aura within 48 hours of infusion start
