Study summary

The purpose of this study is to characterize the cell (the basic building block of all living things) populations and inflammatory (pain and swelling) mediator responses in suction skin blister fluid after allergic skin reaction (ASR) [rash] induction with D. Pteronyssinus [house dust mite (HDM)], Alternaria alternata, or Aspergillus fumigatus allergens in participants with atopic dermatitis (AD) [Skin rash, Eczema] or allergic asthma (AA) [breathing disorder in which there is a wheezing and difficulty breathing].

Read the detailed description

This is an interventional (a treatment given during the course of a research study) and multicenter (when more than one hospital or medical school team work on a medical research study) study. The study will consist of 3 Phases: Screening Phase (Up to 4 weeks), Data Collection Phase (9 days) and, Follow-up Phase (7 days). The maximum study duration for each participant will not exceed 43 days. Primarily, the cell populations and inflammatory mediator responses in suction skin blister fluid after allergic skin reaction (ASR) will be assessed. Participants' safety will be monitored throughout the study.

Inclusion criteria

  • Participant must have signed an document prior to any study related procedures indicating that they understand the purpose of and procedures required for the study and are willing to participate in the study
  • Participant must be willing/able to adhere to the study visit schedule and other requirements, prohibitions and restrictions specified in this protocol

    * For participants with Asthma:

  • Participant must have a physician documented diagnosis of asthma for at least 12 months before Screening

    * For participants with Atopic Dermatitis:

  • Participant must have a physician documented diagnosis of atopic dermatitis for at least 12 months before Screening based on UK refinement of the Hanifin and Rajka's diagnostic criteria
  • Participant must have atopic dermatitis with and Investigators Global Assessment (IGA) score of 2 to 4 at Screening

Exclusion criteria

Exclusion Criteria:

  • Participant has taken any prohibited or restricted medications as noted below under Prestudy and Concomitant Therapy
  • Participant has received an drug (including investigational vaccines) or used an invasive investigational medical device within 6 weeks or 5 half-lives (whichever is longer) before the Screening visit

    * For participants with Atopic Dermatitis:

  • Participant has evidence of any other skin condition that would interfere with assessment of Atopic Dermatitis (AD)
  • Participant has active AD related infection or has had an active AD infection within 2 weeks of Screening (participants with evidence of colonization on skin swab testing but with no infection are allowed)
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Study arms

  • Experimental
    Healthy + Atopic Dermatitis + Allergic Asthmatic Participants

    Healthy participants will be enrolled in order to allow for training on the overall skin blister induction and fluid aspiration process. Participants with atopic dermatitis (AD) or allergic asthma (AA) will be observed for the use of induced skin blisters after allergic skin reaction (ASR).

    Other: Allergic Skin Reaction (ASR) Testing and Skin Blister Induction

Interventions

  • OtherAllergic Skin Reaction (ASR) Testing and Skin Blister Induction

    Participants will not receive any intervention in this study. Healthy participants will be enrolled in order to allow for training on the overall skin blister induction and fluid aspiration process. The cell populations and inflammatory mediator responses in suction skin blister fluid after allergic skin reaction (ASR) in participants with atopic dermatitis (AD) or allergic asthma (AA) will be observed.

What researchers measure

Primary outcomes

  1. Cell Concentration in Suction Skin Blister Fluid After Allergic Skin Reaction (ASR) Induction with D. Pteronyssinus (House Dust Mite [HDM]), Alternaria alternata, or Aspergillus fumigatus Allergens

    Cells in the aspirated skin blister fluid will be separated and processed for cell population analysis by flow cytometry and messenger RNA (mRNA) analysis.

    Time frame: Hour 4 after the end of the blister induction

  2. Cell Concentration in Suction Skin Blister Fluid After ASR Induction with D. Pteronyssinus (House Dust Mite), Alternaria alternata, or Aspergillus fumigatus Allergens

    Cells in the aspirated skin blister fluid will be separated and processed for cell population analysis by flow cytometry and mRNA analysis.

    Time frame: Hour 24 after the end of the blister induction

  3. Levels of Inflammatory Mediators in Suction Skin Blister Fluid After ASR Induction with D. Pteronyssinus (House Dust Mite), Alternaria alternata, or Aspergillus fumigatus Allergens

    The remaining fluid from aspirated skin blister fluid after separated and processed for cell population analysis will be assessed for inflammatory mediator responses. Inflammatory cytokines and other soluble mediators in blister fluid will be measured by immunoassay.

    Time frame: Hour 4 after the end of the blister induction

  4. Levels of Inflammatory Mediators in Suction Skin Blister Fluid After ASR Induction with D. Pteronyssinus (House Dust Mite), Alternaria alternata, or Aspergillus fumigatus Allergens

    The remaining fluid from aspirated skin blister fluid after separated and processed for cell population analysis will be assessed for inflammatory mediator responses. Inflammatory cytokines and other soluble mediators in blister fluid will be measured by immunoassay.

    Time frame: Hour 24 after the end of the blister induction

Secondary outcomes

  1. Success Percentage of Repeated Skin Blister Induction and Blister Fluid Aspiration

    Success percentage for blister induction will be defined as number of blisters formed with recovery of at least 200 microliter (μL) of blister fluid, divided by the total blisters induced.

    Time frame: Day 1 and 8

  2. Cell Concentration in Suction Skin Blister Fluid After ASR Induction with Non-protease Allergens

    Cells in the aspirated skin blister fluid will be separated and processed for cell population analysis by flow cytometry and mRNA analysis.

    Time frame: 4 and 24 Hours after the end of the blister induction

  3. Levels of Inflammatory Mediators in Suction Skin Blister Fluid After ASR Induction with Non-protease Allergens

    The remaining fluid from aspirated skin blister fluid after separated and processed for cell population analysis will be assessed for inflammatory mediator responses. Inflammatory cytokines and other soluble mediators in blister fluid will be measured by immunoassay.

    Time frame: 4 and 24 Hours after the end of the blister induction

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 6, 2015, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
