About this study

The purpose of this study is to evaluate the percutaneous transportation and pharmacokinetics of melatonincream 12,5% when used on 80% of the body area. A test battery consisting of blood, saliva, urine samples at 1,2,3,4,5,6,7,8,12,24 and 36 hours after cream application. Cognitive parameters are investigated using KSS, FTT and CRT tests at above mentioned time points.

What is being measured

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

  1. Changes in Karolinska Sleepiness Scale after application of melatonincream 12,5% on 80% of the body-surface area.

    Karolinska sleepiness scale is a valid scale for measurement of subjective sleepiness in individuals.

    This scale is used to detect any changes in subjective sleepiness over a time period of 36 hours after application of melatonincream 12,5% on 80% of the body-surface area.

    Measured: 1,2,3,4,5,6,7,8,12,24 and 36 hours post exposure.

Secondary outcomes (5)
  1. Changes in continuous reaction time over a time period of 36 hours after application of melatonin cream 12,5% on 80% of the body surface area.

    Continuous reaction time is a neuropsychological test designed to investigate endurance and attention by testing the persons ability to react to external stimuli over a given time period.

    This parameter is used to detect changes in endurance and attention over a time period of 36 hours after application of melatonincream 12,5% on 80% of the body-surface area.

    Measured: 1,2,3,4,5,6,7,8,12,24 and 36 hours post exposure.

  2. Changes in finger tapping test over a time period of 36 hours after application of melatonin cream 12,5% on 80% of the body surface area.

    Finger tapping test is a simple way to investigate psychomotoric speed and control. Impaired psychomotoric speed is accepted as a predictor for cerebral dysfunction.

    This parameter is used to detect changes in psychomotoric speed and control over a time period of 36 hours after application of melatonincream 12,5% on 80% of the body surface area.

    Measured: 1,2,3,4,5,6,7,8,12,24 and 36 hours post exposure.

  3. Changes in serum melatonin concentration

    Blood samples are collected at the above mentioned time points. Serum melatonin is evaluated by laboratory tests.

    Blood samples are used to detect the changes in serum melatonin concentration after application of melatonin cream 12,5% on 80% of the body surface area.

    Measured: 1,2,3,4,5,6,7,8,12,24 and 36 hours post exposure.

  4. Changes in saliva melatonin concentration.

    Saliva samples are collected at above mentioned time points. The concentration of melatonin in saliva is tested using laboratory analyses.

    Saliva samples are collected to detect changes in saliva melatonin concentration over a time period of 36 hours after application of melatonincream 12,5% on 80% of the body surface area.

    Measured: 1,2,3,4,5,6,7,8,12,24 and 36 hours post exposure

  5. Changes in urine melatonin concentration

    Urine is collected in the above mentioned time intervals, and the concentration of melatonin is found by measuring the concentration of the metabolite 6-sulfatoxymelatonin using RIA.

    The urine samples are collected and used to detect changes in 6-sulfatoxymelatonin concentration over a time period of 36 hours after application of melatonincream on 80% of the body surface area.

    Measured: 0-4,4-8,8-12,12-24 and 24-36.

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Melatonin in people with Solar Skin Damage, run by Zealand University Hospital 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 7 inclusion and 5 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 17 Nov 2014. 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. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

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?

Changes in Karolinska Sleepiness Scale after application of melatonincream 12,5% on 80% of the body-surface area. (time frame: 1,2,3,4,5,6,7,8,12,24 and 36 hours post exposure.). 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 17 Nov 2014.
