A Study to Determine Serum and Skin Biopsy Biomarkers in Patients Receiving Topical Corticosteroid (TCS) and Following TCS Withdrawal (GNE-AD)

January 15, 2019 updated by: University of California, San Francisco

A Study in Atopic Dermatitis to Determine Serum and Skin Biopsy Biomarkers in Patients Receiving Topical Corticosteroid (TCS) and Following TCS Withdrawal

The purpose of this study is to assess the differential expression of AD biomarkers in serum, plasma, and skin biopsies from both lesional and non-lesional skin in moderate to severe AD patients in the presence of TCS and after withdrawal from TCS.

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 exploratory study consists of four visits to the investigator site post screening: at Weeks 0 (baseline), 2, 6 and 8 (Figure 1). At the first visit (baseline), patients who have met the screening eligibility criteria will be started on a stable TCS regimen for a total of two weeks. At the second visit (Week 2) following two weeks of therapy on stable TCS, patients will stop TCS and blood, serum, plasma and two 6mm punch biopsies (one lesional (L) and one non-lesional (NL) skin) will be obtained. At the third visit (Week 6), after four weeks receiving no TCS, the same sample collections will be repeated and the patients will then enter a two week safety follow up. At the end of the safety follow up (last visit, Week 8) and after obtaining written informed consent by the patient, blood, serum and plasma samples mav be collected.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  1. Male or female patients 18-75 years of age
  2. AD diagnosed by the Rajka/Hanifin criteria at the time of screening and that has been present for at least 1 year
  3. History of inadequate response to a stable regimen of TCS for 1 month (in the 3 months immediately preceding the screening visit) as treatment for their AD
  4. Eczema Area and Severity Index (EASI) score ≥ 14 at the screening and baseline visits
  5. Investigator's Global Assessment (IGA; 5-point) score ≥ 3 at the screening and baseline visits
  6. ≥10% body surface area involvement by AD

  7. A washout period prior to screening for those patients who have previously received the following medications:

    • Cyclosporine/Oral Steroids/Imuran/Mycophenolate Mofetil/Other systemic immunosuppressants: 4 weeks
    • Phototherapy: 4 weeks
    • Biologics: 5 half lives of the drug

Exclusion Criteria:

  1. Evidence of other concomitant skin conditions (e.g., psoriasis or contact dermatitis)
  2. Use of topical calcineurin inhibitors within 4 weeks of screening
  3. Hypersensitivity to TCS or to any other ingredients contained by the emollient or TCS product used during the study
  4. Evidence of active skin infection at screening or baseline visit
  5. Evidence or history of active or latent infections such as tuberculosis or hepatitis C
  6. Patient clinical condition is not appropriate for treatment with protocol prescribed TCS
  7. Use of an investigational agent within 4 weeks prior to screening or within 5 half-lives of the investigational agent, whichever is longer
  8. Use of a tanning booth/parlor within 4 weeks before the baseline visit
  9. Use of any anti-histamine medication within 4 weeks before the baseline visit.
  10. History of any condition (e.g. bleeding diathesis) that may predispose the patient to complications associated with the planned skin biopsy procedures
  11. Known current malignancy or current evaluation for a potential malignancy, including basal or squamous cell carcinoma of the skin or carcinoma in situ
  12. Other clinically significant medical disease that is uncontrolled despite treatment that is likely, in the opinion of the investigator, to impact the patient's ability to participate in the study or to impact the study pharmacodynamic (PD), or safety assessments
  13. Unwillingness or inability to comply with the study protocol for any other reason.

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
Change in Blood and Tissue Levels of Biomarkers Following Treatment of Atopic Dermatitis With Topical Corticosteroids.
Time Frame: Baseline to Week 8
The blood and skin biomarkers to be evaluated include but are not limited to eosinophils, Immunoglobulin E (IgE), Interleukin 13 (IL-13), Chemokine ligand 13 (CCL-13), and Chemokine ligand 17 (CCL-17). These biomarkers will be evaluated for differential gene expression and protein levels in samples obtained from atopic dermatitis patients on and off topical corticosteroid treatment.
