About this study

Official title: Investigating the Role of Skin Resident T Cells in Atopic Eczema and Responses to Antigen Challenge

The aim of this study is to investigate the mechanisms behind the immune dysfunction that occurs in atopic eczema (or atopic dermatitis).

Read the detailed description

Atopic eczema is a chronic inflammatory skin disease that affects 15-20% of children and 12% of adults and leads to significant loss of quality of life. It results from a complex interaction of genetic and environmental factors, and is characterised by dysregulation of the cutaneous immune system. Specifically, in the skin of eczema patients there is a persistence of T lymphocytes (a crucial cell involved in regulating the immune system), and an overproduction of certain cytokines (signalling molecules that are essential in producing inflammatory responses).

The study intends to investigate the causes of atopic eczema by examining the number, characteristics and function of T lymphocytes in the skin and the blood of eczema patients, as well as the types of cytokine they produce. To achieve this the investigators aim to take skin biopsies, tissue fluid (from induced skin suction blisters) and blood samples from adult eczema patients and healthy controls for analysis. Additionally, in these groups a cutaneous immune response will be initiated by injecting tuberculin protein purified derivative (the Mantoux test) into the skin, to further investigate how the behaviour of T lymphocytes varies between eczema patients and healthy controls.

This research is important in view of the high prevalence of atopic eczema in the population. An improved understanding of its causes will hopefully lead to more effective treatments for this condition in future.

Study groups in NCT02102841
Study groupRoleWhat they receive
Skin biopsyExperimental5mm skin punch biopsy on forearm
Receives: Procedure: Skin biopsy
Skin suction blisterExperimentalSkin suction blister induced on forearm
Receives: Procedure: Skin suction blister
Mantoux, skin biopsy, suction blisterExperimental0.1ml tuberculin purified protein derivative (PPD) is injected intradermally into an area of non-lesional skin on the volar aspect of each of the patient's forearms. This is followed by a skin biopsy on one arm and induction of a skin suction blister on the other arm.
Receives: Procedure: Skin biopsy; Procedure: Skin suction blister; Biological: Mantoux test

What is being measured

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

  1. Number of regulatory T cells in lesional skin of atopic dermatitis patients compared to healthy volunteers

Questions about this trial

What is this clinical trial studying?

A study testing Skin biopsy, Skin suction blister and Mantoux test in people with Atopic Dermatitis, run by University College, London at 1 site in United Kingdom.

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 2 inclusion and 13 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: withdrawn, as of the sponsor's last update on 30 Apr 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 Kingdom. 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 was withdrawn before enrolling participants, so there are no results.

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?

Number of regulatory T cells in lesional skin of atopic dermatitis patients compared to healthy volunteers (time frame: Up to 14 days). 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 NCT02102841, which also lists 1 linked publication.

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 30 Apr 2021; AzTrials last refreshed its copy on 6 Nov 2026.
