Multiomics After Cold Pressor Test of People Who Are Unable to Have Headache
A study testing Blood samples in people with Headache and Headache Disorders, run by Danish Headache Center at 1 site in Denmark.
Trial summary
Headaches are extremely common illnesses with a combined lifetime prevalence of 90-99% in Europe. Despite this high prevalence, there are persons who have never, in their whole life, encountered a headache. Read more about this study

About this study
Official title: Pain Perception, Headache Provocation and Multiomics of People Who Are Unable to Have Headache
Headaches are extremely common illnesses with a combined lifetime prevalence of 90-99% in Europe. Despite this high prevalence, there are persons who have never, in their whole life, encountered a headache.
The aim of the study is to identify factors that protect against headache by studying multiomics in people who never have had a headache (headache resistant) versus non-resistant controls.

The investigators will measure multiomic changes (transcriptomics and metabolomics) after pain induction by Cold Pressor Test. 3 blood samples, two for RNA and one for metabolites are taken 5 minutes before a Cold Pressor Test and again 1 hour after the Cold Pressor Test.
The investigators hope to contribute with novelty to the current understanding of headache pathophysiology and development of more efficient treatment of headache.

Questions about this trial
What is this clinical trial studying?
A study testing Blood samples in people with Headache and Headache Disorders, 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 2 inclusion and 8 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 25 Mar 2021. 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. 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?
Transcriptomic changes (time frame: 1 hour). The study lists 2 primary outcomes in all. 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 25 Mar 2021.
