Trial summary

The purpose of this study is to assess both the sleep and circadian (24-hourly biological rhythms) physiology of people with cluster headache. For sufferers with the episodic form of the disorder this will involve observation at two separate time points, once when experiencing attacks (in-bout) and once when attack… Read more about this study

About this study

Official title: Characterisation of Sleep and Circadian Physiology in Individuals With Cluster Headache

The purpose of this study is to assess both the sleep and circadian (24-hourly biological rhythms) physiology of people with cluster headache. For sufferers with the episodic form of the disorder this will involve observation at two separate time points, once when experiencing attacks (in-bout) and once when attack free (out-of-bout).

The study will include measurement of basic rest-activity patterns, sleep timing and timing of individual attacks, as well as a more detailed study recording sleep and circadian rhythms under clinical conditions over consecutive nights.

Studying the differences in these processes in single individuals when they are both experiencing and free from attacks might provide insight into the brain mechanisms involved in triggering the bouts of attacks and individual attacks themselves. An improved understanding of this area may help design improved treatment options in future.

Questions about this trial

What is this clinical trial studying?

An observational study of Cluster Headache, run by University of Surrey at 1 site in United Kingdom.

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 2 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 13 Apr 2017. 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 United Kingdom. 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?

amplitude and phase of circadian rhythm of melatonin (time frame: 36 hours). 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 13 Apr 2017.
