IL-4 and Insulin Resistance for Treatment of Patients With Atopic Dermatitis

February 22, 2024 updated by: Elena Anna (Eleanna) De Filippis, M.D., Ph.D., Mayo Clinic

IL-4 & Insulin Resistance in Patients With Atopic Dermatitis

The purpose of this study is to better understand the interactions between the innate immune system, in particular eosinophils, their secreted cytokines (interleukin-4), and metabolism in human health and disease states such as obesity and insulin resistance.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.
Completed

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

Patients with a body mass index (BMI) less than 30 kg/m2 and a history of atopic dermatitis on long-term (greater than 6 months) treatment with dupilumab. Researchers will compare in vivo evaluations of insulin sensitivity in subjects on dupilumab vs subjects matched for similar weight and BMI, with atopic dermatitis, but without dupilumab therapy (phototherapy).

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

Enrollment (Actual)

Enrollment

The number of participants in a clinical study. The "anticipated" enrollment is the target number of participants that the researchers need for the study.

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

14 years to 56 years (Adult)

Accepts Healthy Volunteers

Yes

Exclusion Criteria:

  • Any prescription for systemic glucocorticoid, immunosuppressant, antidiabetic medications in the past 6 months.

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
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.
Experimental: Subjects on Dupilumab
individuals with atopic dermatitis placed on dupilumab for more than 6 months will be eligible to this study. Their metabolic profile will be compared to the group of "Subjects on Phototherapy"
Drug: Dupilumab
dupilumab injections will be prescribed and managed by dermatology as standard of care
Active Comparator: Subjects on Phototherapy
individuals with atopic dermatitis placed on phototherapy for more than 6 months will be eligible to this study to serve as an active comparator to the "Subjects with Dupilumab"
Other: Photo therapy
light therapy will be prescribed and managed by dermatology as standard of care
Other Names:
  • light therapy

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
Homa IR
Time Frame: baseline
Homeostatic Model Assessment of Insulin Resistance will be calculated by multiplying the fasting glucose concentration (mg/dl) by the fasting insulin concentration (mmol/L).
baseline
Matsuda Index
Time Frame: baseline
The Matsuda index is able to estimate peripheral insulin sensitivity by computing the product of glucose and insulin collected during the OGTT.
baseline

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Adipo-IR
Time Frame: baseline
Adipo-IR will be calculated by multiplying the fasting FFA concentration (mmol/L) by the fasting insulin concentration (pmol/L) obtained during the baseline blood collection during the oral glucose tolerance test
baseline
Systemic inflammatory markers
Time Frame: baseline
Circulating plasma levels of inflammatory markers interleukin 1 (IL1), Tumor necrosis factor alpha (TNFa), highly sensitive C-reactive protein (hs-CRP), Monocyte Chemoattractant Protein 1 (MCP1), interleukin 6 (IL-6), Interleukin 4 (IL-4) and interleukin 13 (IL13)
baseline
Adipokines
Time Frame: baseline
We will measure the plasma levels of adipokines (leptin and adiponectin) by radioimmunoassay and ELISA in all subjects recruited and compared across study group
baseline
Fasting Free Fatty Acid
Time Frame: baseline
During the OGTT, we will collect fasting blood to assess levels of plasma free fatty acid (mmol/L). These values will be compared across the 2 different group studied.
