About this study

Official title: Analysis of the Response of Subjects With Atopic Dermatitis to Oral Vitamin D3 by Measurement of Antimicrobial Peptide Expression in Skin and Saliva

This study will examine whether administration of oral Vitamin D3 given over 21 days will change the antimicrobial peptide expression in the skin or saliva of subjects with Atopic Dermatitis (AD). This study will help researchers determine if the lack of the expression of antimicrobial peptides in individuals with AD plays a role in the susceptibility to eczema vaccinatum (EV).

Read the detailed description

Atopic Dermatitis (AD) is a chronic inflammatory skin disorder in which the skin becomes extremely itchy and is susceptible to recurrent skin infections. AD is thought to occur from a combination of immunological, genetic, and environmental factors. Individuals with AD are at risk for developing a severe and widely disseminated infection called eczema vaccinatum (EV). EV is caused when the live attenuated vaccinia virus in the vaccine reproduces and spreads throughout the body. Individuals with AD lack certain antimicrobial peptides, specifically cathelicidins.

This trial also includes a sub-study with individuals who have psoriasis. Psoriasis is also an immune-mediated skin disease, and is characterized by scaling skin and inflammation (pain, swelling, heat, and redness). Most psoriasis cause patches of thick, red skin with silvery scales. These patches can itch or feel sore. This sub-study will provide additional information on psoriatic responses to oral vitamin D. (Originally listed separately as ADVN-CATH-03-01).

What is being measured

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

  1. Change From Baseline on Day 21 in Relative Abundance of CAMP mRNA in Lesional and Non-Lesional Skin for Atopic Dermatitis (AD) Participants Who Received Oral Vitamin D3 Versus Vitamin D3-Placebo

    Cathelicidin (CAMP) Messenger Ribonucleic Acid (mRNA) expression from skin biopsies measured by quantitative real time polymerase chain reaction (qRT-PCR). Average delta cycle threshold (CT) adjusted for non-atopic average at baseline on the arithmetic scale = [(average of (CT for CAMP - CT for Glyceraldehyde-3-phosphate dehydrogenase (GAPDH)) across replicates) - (the average of (CT for CAMP - CT for GAPDH) for non-atopic subjects at baseline)]. A negative value indicates a drop from baseline and a positive value indicates an increase from baseline. Cathelicidin amount is clinically significant as it is necessary to resist infection. Cathelicidin amount is not known to be clinically relevant to the clinical signs of dermatitis associated with AD.

    Measured: Baseline to Day 21

  2. Change From Baseline on Day 21 in Relative Abundance of CAMP mRNA in Non-Lesional Skin for Non-Atopic Dermatitis (Non-AD) Participants Who Received Oral Vitamin D3 Versus Vitamin D3-Placebo

    Cathelicidin (CAMP) Messenger Ribonucleic Acid (mRNA) expression from skin biopsies measured by quantitative real time polymerase chain reaction (qRT-PCR). Average delta cycle threshold (CT) adjusted for non-atopic average at baseline on the arithmetic scale = [(average of (CT for CAMP - CT for Glyceraldehyde-3-phosphate dehydrogenase (GAPDH)) across replicates) - (the average of (CT for CAMP - CT for GAPDH) for non-atopic subjects at baseline)]. Non-AD is defined as a healthy volunteer without atopic dermatitis, therefore the lesional skin-type was not measured in this group. A negative value indicates a drop from baseline and a positive value indicates an increase from baseline. Cathelicidin amount is clinically significant as it is necessary to resist infection. Cathelicidin amount is not known to be clinically relevant to the clinical signs of dermatitis associated with AD.

    Measured: Baseline to Day 21

  3. Change From Baseline on Day 21 in Relative Abundance of CAMP mRNA in Lesional and Non-Lesional Skin for Psoriatic Participants Who Received Vitamin D3 Versus Vitamin D3-Placebo

    Cathelicidin (CAMP) messenger ribonucleic acid (mRNA) expression from skin biopsies measured by quantitative real time polymerase chain reaction (qRT-PCR). Average delta cycle threshold (CT) adjusted for non-atopic average at baseline on the arithmetic scale = [(average of (CT for CAMP - CT for Glyceraldehyde-3-phosphate dehydrogenase (GAPDH)) across replicates) - (the average of (CT for CAMP - CT for GAPDH) for non-atopic subjects at baseline)]. A negative value indicates a drop from baseline and a positive value indicates an increase from baseline, Cathelicidin abundance in psoriasis has been hypothesized to correlate with increased inflammation. No direct clinical correlation is known.

    Measured: Baseline to Day 21

  4. Change From Baseline on Day 21 in Relative Abundance of HBD-3 mRNA in Lesional and Non-Lesional Skin for Atopic Dermatitis (AD) Participants Who Received Oral Vitamin D3 Versus Vitamin D3-Placebo

    Human Beta-defensin 3 (HBD-3) Messenger Ribonucleic Acid (mRNA) expression from skin biopsies as measured by quantitative real time polymerase chain reaction (qRT-PCR). Average delta cycle threshold (CT) adjusted for non-atopic average at baseline on the arithmetic scale = [(average of (CT for CAMP - CT for Glyceraldehyde-3-phosphate dehydrogenase (GAPDH)) across replicates) - (the average of (CT for CAMP - CT for GAPDH) for non-atopic subjects at baseline)]. A negative value indicates a drop from baseline and a positive value indicates an increase from baseline. HBD-3 amount is clinically significant as it is necessary to resist infection. HBD-3 amount is not known to be clinically relevant to the clinical signs of dermatitis associated with AD.

    Measured: Baseline to Day 21

  5. Change From Baseline on Day 21 in Relative Abundance of HBD-3 mRNA in Non-Lesional Skin for Non-Atopic Dermatitis (Non-AD) Participants Who Received Oral Vitamin D3 Versus Vitamin D3-Placebo

    Human Beta-defensin 3 (HBD-3) Messenger Ribonucleic Acid (mRNA) expression from skin biopsies measured by quantitative real time polymerase chain reaction (qRT-PCR). Average delta cycle threshold (CT) adjusted for non-atopic average at baseline on the arithmetic scale = [(average of (CT for CAMP - CT for Glyceraldehyde-3-phosphate dehydrogenase (GAPDH)) across replicates) - (the average of (CT for CAMP - CT for GAPDH) for non-atopic subjects at baseline)]. Non-AD is defined as a healthy volunteer without atopic dermatitis, therefore the lesional skin-type was not measured in this group. A negative value indicates a drop from baseline and a positive value indicates an increase from baseline. HBD-3 amount is clinically significant as it is necessary to resist infection. HBD-3 amount is not known to be clinically relevant to the clinical signs of dermatitis associated with AD.

    Measured: Baseline to Day 21

  6. Change From Baseline on Day 21 in Relative Abundance of HBD-3 mRNA in Lesional and Non-Lesional Skin for Psoriatic Participants Who Received Vitamin D3 Versus Vitamin D3-Placebo

    Human Beta-defensin 3 (HBD-3) Messenger Ribonucleic acid (mRNA) expression from skin biopsies measured by quantitative real time polymerase chain reaction (qRT-PCR). Average delta cycle threshold (CT) adjusted for non-atopic average at baseline on the arithmetic scale = [(average of (CT for CAMP - CT for Glyceraldehyde-3-phosphate dehydrogenase (GAPDH)) across replicates) - (the average of (CT for CAMP - CT for GAPDH) for non-atopic subjects at baseline)]. A negative value indicates a drop from baseline and a positive value indicates an increase from baseline. There is no known clinical correlation between HBD-3 and psoriasis.

Secondary outcomes (3)
  1. Change From Baseline on Day 21 in Relative Abundance of IL-13 mRNA in Lesional and Non-Lesional Skin for Atopic Dermatitis (AD) Participants Who Received Vitamin D3 Versus Vitamin D3-Placebo

    Cytokine interleukin-13 (IL-13) Messenger Ribonucleic Acid (mRNA) expression from skin biopsies measured by quantitative real time polymerase chain reaction (qRT-PCR).

A Phase 2 study testing Vitamin D3 in people with Atopic Dermatitis and Psoriasis, run by National Institute of Allergy and Infectious Diseases (NIAID) at 3 sites in United States.

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 4 inclusion and 51 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 12 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 3 sites in United States. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 22 Jan 2013). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Change From Baseline on Day 21 in Relative Abundance of CAMP mRNA in Lesional and Non-Lesional Skin for Atopic Dermatitis (AD) Participants Who Received Oral Vitamin D3 Versus Vitamin D3-Placebo (time frame: Baseline to Day 21). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00789880, which also lists 2 linked publications.

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?
