Trial summary

The investigators hypothesized that migraine without patients with many genetic loci associated with migraine (high genetic load) would be more sensitive and get provoked more migraine attacks by calcitonin gene-related peptide (CGRP) compared to patients with few genetic loci associated with migraine (low genetic… Read more about this study

About this study

The investigators hypothesized that migraine without patients with many genetic loci associated with migraine (high genetic load) would be more sensitive and get provoked more migraine attacks by calcitonin gene-related peptide (CGRP) compared to patients with few genetic loci associated with migraine (low genetic load).

Read the detailed description

Migraine is a very prevalent neurological disorder with a strong genetic factor. The common forms of migraine have a multifactorial and polygenic pattern of inheritance and genetics research is crucial for a deeper understanding of migraine mechanisms. Recently, 12 genetic loci have been identified to be associated with migraine with (MA) and without aura (MA) in four large genome-wide association studies (GWAS). The functional consequences of these genetic loci in humans are yet unknown.

Calcitonin gene-related peptide (CGRP) is a neuropeptide which plays a crucial role in the pathophysiology of migraine and is present in migraine relevant structures. CGRP can induce migraine attacks in MO patients via an adenosine monophosphate (cAMP) dependent pathway and CGRP antagonism is efficient in the treatment of migraine attacks. Also, a recent study has showed that intracellular accumulation of cAMP is crucial for the induction of migraine attacks. However, CGRP does not cause migraine attacks in familial hemiplegic migraine (FHM), an autosomal dominant subtype of MA.

The phenotype of the migraine inducing effects of CGRP might therefore be linked to some of the 12 genetic susceptibility loci that have been identified. One of the genetic loci (rs13208321) is located in a gene (FHL5) that is associated with the regulation of cAMP-responsive elements.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. CGRP induced migraine attacks in patients with high and low genetic load

    The difference in incidence of migraine-like attacks between patients with high genetic load and patients with low genetic load using verbal rating scale (VRS).

    Measured: Change from baseline in headache intensity at 12 hours after the start of infusion of CGRP

Secondary outcomes (1)
  1. CGRP induced migraine attacks in patients with high and low genetic load

    The difference in area under the curve (AUC) for headache intensity scores (0-12 hours)

    Measured: Change from baseline in headache intensity at 12 hours after the start of infusion of CGRP

Questions about this trial

What is this clinical trial studying?

A study testing CGRP in people with Migraine Without Aura, run by Danish Headache Center.

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 1 inclusion and 7 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: finished, as of the sponsor's last update on 2 Aug 2022. Status can change between updates, so confirm with the study contact before making plans.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

CGRP induced migraine attacks in patients with high and low genetic load (time frame: Change from baseline in headache intensity at 12 hours after the start of infusion of CGRP). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 2 Aug 2022.
