About this study

Official title: Integrated Extreme Trait Analysis to Understand the Etiology of Eczema Herpeticum (ADRN-06)

Atopic dermatitis, also called eczema, is a disease with dry, scaly, itchy skin. Those with atopic dermatitis may have complications from skin infections such as eczema herpeticum after herpes simplex virus (HSV) infection. Symptoms of eczema herpeticum include fever and clusters of itchy blisters which crust over and form sores. Although exposure to HSV is widespread, most people clear the virus and only a subset of individuals with atopic dermatitis develop eczema herpeticum.

The purpose of this study is to determine why some individuals with atopic dermatitis are at higher risk for recurrent skin infections with HSV. The study team will compare how people with atopic dermatitis with a history of recurrent eczema herpeticum, people with atopic dermatitis without a history of eczema herpeticum, and people without atopic dermatitis respond to HSV.

Read the detailed description

This study uses whole genome sequencing (WGS) technology to identify genetic variants that confer risk of recurrent atopic dermatitis with a history of eczema herpeticum (ADEH+), with ≥3 eczema herpeticum (EH) episodes.

A small subgroup of individuals with atopic dermatitis (AD) suffer from life-threatening disseminated herpes simplex virus (HSV) skin infections, termed eczema herpeticum (ADEH+). The manifestation of ADEH+ however is not simply a consequence of herpes simplex virus type 1 (HSV-1) infections, since the majority of the US population is latently infected with HSV-1 from an early age. Most importantly, there is a bimodality in the recurrence of eczema herpeticum (EH) episodes; most individuals have only a single episode but a subgroup of ADEH+ individuals has 3 or more episodes.

This study aims to conduct an extreme trait investigation of ADEH+ with recurrent EH, ≥3 episodes, compared to AD without a history of eczema herpeticum (ADEH-), using whole genome sequencing.

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 8 inclusion and 10 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 14 Jan 2021. 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 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

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?

The Difference in Frequency of Rare Deleterious Coding Genetic Variants between Subjects with Recurrent Atopic Dermatitis (AD) and a History of Eczema Herpeticum (ADEH+) Compared to Controls - Using Whole Genome Sequencing (time frame: 3 years). The study lists 2 primary outcomes in all. 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 14 Jan 2021.
