Sample Collection Study to Assess Prevalence of Gene Mutations: Establishing Population Norms

October 14, 2021 updated by: DermTech

A Sample Collection Study to Assess the Prevalence of Gene Mutations Associated With Photoaging in Facial Skin From Adults: Establishing Population Norms

This is a multi-center, sample collection study to quantitatively assess the presence of gene mutations in subject's skin collected non-invasively. Subjects who consult with a dermatologist or other clinicians will be approached for participation in the study. Once IRB approved informed consent is obtain, subject demographic information, history of sun exposure and samples will be collected.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

This is a multi-center, sample collection study to quantitatively assess the presence of gene mutations in subject's skin collected non-invasively. Subjects who consult with a dermatologist or other clinicians will be approached for participation in the study. Once confirmation of participation is confirmed subjects will undergo the informed consent process.

Once consented the subject will have their medical history reviewed, concomitant medications and demographic information recorded, complete a sun-exposure questionnaire, have photoaging characteristics (such as melasma, wrinkles, AK lesion(s)) recorded, record their assessment of photoaging, have skin samples collected non-invasively and complete the local skin reaction and local tolerability assessments. A select number of subjects will also have a facial photograph taken.

If the location to be sampled contains a lesion, then the collection should occur as close as possible to the target area. The site staff and/or subject will be responsible for collecting the skin samples.

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

21 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

Yes

Genders Eligible for Study

Probability Sample

Study Population

Up to approximately 5,000 adults presenting to clinics for consultations will be enrolled into this study.

Subjects will be enrolled across a wide range of demographics and age ranges. A minimum of 3000 subjects of Fitzpatrick Skin Type I-III skin types (Group 1) and 1000 subjects of Fitzpatrick IV-VI (Group 2) will be enrolled. This will include, but is not limited to races such as Caucasian, African American, and subjects of Asian descent. At least 100 subjects per Fitzpatrick Skin Type group will be from the following age ranges; 21-30, 31-40, 41-50, 51-60 and >61 will be enrolled.

Description

Inclusion Criteria:

  1. Males and females at least 21 years of age presenting to the clinic for medical consultation;
  2. In good health, determined by no clinically significant findings from medical history,
  3. Willing to complete all study procedures required by the protocol; and
  4. Willing to provide informed consent to participate in this trial.

Exclusion Criteria:

  1. Have any skin disorder including acne, rosacea, psoriasis, atopic dermatitis and active skin cancer(s) that appear in the facial area where sample collection will be taken and could confound the results of the trial;
  2. Has a suspicious lesion (i.e., actinic keratosis lesion) in an area that is expected to be sampled and requires further medical follow-up,
  3. Pregnant or breast feeding,
  4. Hospitalization within 4 weeks before enrollment,
  5. Previously provided samples for this study,
  6. Receipt of any investigational drug therapy within four weeks of study enrollment, or concurrent participation in another interventional clinical study,
  7. Documented substance abuse, any other significant medical condition that would indicate an unreasonable risk to the potential study participate or potential interference with the procedures, or would negatively affect the study subject's reliability and compliance with the study schedule of events, and
  8. Chemical peel or treatment with a laser in the facial area within 3 months prior to enrollment.

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
Prevalence rate of mutations
Time Frame: 1 day
The prevalence rate of selected DNA mutations will be quantitated
1 day

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
Correlate gene mutations with demographic information
Time Frame: 1 day
prevalence of mutations relative to age, sex, race and ethnicity
1 day
Correlation gene mutation with sun exposure scores
