Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

All

Sampling Method

Description

Inclusion Criteria:

  • Males or females ages 18 years and above
  • Capable of giving informed consent
  • Adults who are either healthy, normal volunteers or those with a skin disease including but not limited to eczema, psoriasis, acne or other inflammatory dermatoses

Design Details

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Normal, healthy volunteers
Normal, healthy volunteers without any skin pathology will be asked to undergo various procedures to evaluate their sleep and skin health.
Volunteers with skin pathology
Volunteers with skin pathology including but not limited to eczema, psoriasis, acne, and other inflammatory dermatoses will be asked to undergo various procedures to evaluate their sleep and skin health.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Analysis of Sleep Pattern via Actigraphy, Polysomnography & Questionnaires
Time Frame: 7-14 days
The volunteers may be asked to wear a wrist actigraph to measure movement. This watch would be worn for 24 hours per day for 7-14 days. The volunteer may also be asked to fill out questionnaires regarding their sleep patterns. Note: Other methods of assessing sleep patterns may also be used including a portable polysomnogram or a standard, overnight sleep study.
7-14 days
Evaluation of skin (both in terms of skin aging and skin disease)
Time Frame: Only once during the study or at specific time points depending on what other procedures are being performed
The volunteers may have their skin evaluated for skin aging using the SCINEXA tool. Volunteers with psoriasis may have their skin evaluated via PASI and/or PGA assessments. Volunteers may have photographs taken to compare clinical appearance with laboratory and research findings.
Only once during the study or at specific time points depending on what other procedures are being performed

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Sample Analysis (from skin, blood, urine, saliva and hair follicle samples)
Time Frame: Only once during the study or at specific time points depending on what other procedures are being performed
Skin, blood, urine, saliva and hair follicle samples may be collected from some volunteers to look at various markers related to sleep, the circadian rhythm and skin disease.
Only once during the study or at specific time points depending on what other procedures are being performed
Skin Barrier Recovery (via TEWL measurement)
Time Frame: Only once during the study or at specific time points depending on what other procedures are being performed
Skin barrier recovery via Transepidermal Water Loss (TEWL) measurement may be assessed in some volunteers.
Only once during the study or at specific time points depending on what other procedures are being performed
MED Testing & Recovery from UV-induced erythema
Time Frame: 24 hours
MED Testing & Recovery from UV-induced erythema may be assessed in some volunteers.
24 hours

Study record dates

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start (Actual)

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.
March 1, 2015

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
August 1, 2020

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
