What You Need to Know Before You Apply

What is the purpose of this trial?

This trial aims to understand the genetic patterns linked to atopic dermatitis (AD), a common skin condition that causes itchy and inflamed skin. Researchers examine how these patterns change when treated with standard medications like topical steroids and dupilumab, an injectable medication. The study compares these patterns in people with mild and moderate-severe AD and those without the condition. It is ideal for individuals who have had chronic AD for at least a year and experience frequent episodes.

As a Phase 4 trial, the treatment is already FDA-approved and proven effective, helping researchers understand how it benefits more patients.

Will I have to stop taking my current medications?

The trial requires participants to stop using certain medications before joining. You must not use systemic immunosuppressive therapies, certain biologics, or specific topical treatments for a specified period before the study starts. Check with the study team to see if your current medications are affected.

What is the safety track record for these treatments?

Research shows that dupilumab is safe for people with moderate-to-severe atopic dermatitis (AD). Studies have found that both children and adults generally tolerate it well, with most side effects being mild. Common issues include mild eye irritation or redness, but these are not serious. The FDA has approved dupilumab for treating AD, confirming its safety.

Topical corticosteroids, such as triamcinolone acetonide, are often used for skin conditions like AD. These treatments are usually safe when used as directed. Some people might experience mild skin irritation or dryness. Applying them correctly and avoiding use on broken skin can reduce side effects. ^{1 2 3 4 5}

Why are researchers enthusiastic about this study treatment?

Researchers are excited about dupilumab for atopic dermatitis (AD) because it targets a specific part of the immune system, offering a more precise approach compared to traditional treatments like topical corticosteroids. Dupilumab is a monoclonal antibody that blocks the IL-4 and IL-13 pathways, which are crucial in the inflammation process of AD. This mechanism can potentially provide relief with fewer side effects than steroids, which can thin the skin and cause other issues with long-term use. Additionally, for those who haven't responded well to other treatments, dupilumab offers a new hope by addressing the underlying causes of the disease rather than just managing symptoms.

What evidence suggests that this trial's treatments could be effective for atopic dermatitis?

Studies have shown that dupilumab effectively treats moderate-to-severe atopic dermatitis. It significantly improves skin condition, reduces itching, and enhances the quality of life for many patients. Research indicates that both children and adults experience improvements with dupilumab, often noticing results within weeks. In this trial, some participants will continue or begin treatment with dupilumab. Additionally, triamcinolone creams have proven effective in reducing inflammation and itching in atopic dermatitis, serving as a strong first treatment option for many patients. In this trial, some participants will use triamcinolone as part of their treatment regimen. Together, these treatments offer robust options for managing atopic dermatitis symptoms. ^{2 3 4 6 7}

What Are the Treatments Tested in This Trial?

Interventions

• Dupilumab
• Triamcinolone Acetonide

Trial Overview

The study aims to analyze gene expression in skin samples from AD patients responding to standard treatments like topical steroids and Dupilumab. It will compare these profiles between mild and severe cases over ten visits. Non-AD participants are controls. The primary goal is seeing if a specific skin endotype correlates with AD severity.

How Is the Trial Designed?

Group I: Experienced Dupilumab atopic dermatitis participants Experimental Treatment 1 Intervention

AD participants already on dupilumab (for \>= 4 months prior to study entry (20 children, 40 adults)) at the start of the study will continue treatment with dupilumab as prescribed by their physician outside of the study. They may also continue treatment with other prescribed topical AD medications outside of the specified target skin area throughout the study; they may continue treatment with other prescribed topical AD medications within the specified target area from Day 7 through Day 140. Long-term dupilumab participants will apply Vanicream™ beginning at Day 0 through Day 7. Long-term dupilumab participants will return for assessment visits at Day 63 and 140. At Day 140, participants will resume application of Vanicream™ through the End of Study Assessment (Day 168).

Group II: Dupilumab-naïve atopic dermatitis participants Experimental Treatment 4 Interventions

On Day 7, dupilumab-naïve AD participants will begin applying topical corticosteroids twice daily to their specified target area, as well as to active lesions on non-target skin. Dupilumab-naïve AD participants will return for a Steroid Assessment Visit at Day 35, when response to topical corticosteroids will be evaluated at the target site by TAA and targeted EASI scoring, and overall management of AD body-wide by topical steroid/moisturizer treatment will be evaluated by EASI score. Participants who are responsive to topical corticosteroids will continue to use them body-wide through Day 140. Participants who are non-responsive to topical corticosteroids at any time before Day 91 will begin use of dupilumab through their penultimate scheduled visit (Day 140-Day 196) and may continue use of topical corticosteroids outside of their specified target area as needed.

Group III: Non-atopic dermatitis participants Active Control 1 Intervention

Approximately 150 will be non-AD controls (including approximately 50 children, 6-17 years of age, and 100 adults, = 18 years of age) Non-AD control participants will apply Vanicream™ beginning at Day 0 through Day 7. Non-AD control participants will return for assessment visits at Day 35, 91, and 140. At Day 140, participants will resume application of Vanicream™ through the End of Study Assessment (Day 168).

This study analyzed the transcriptome of peripheral blood mononuclear cells (PBMCs) from 56 Chinese patients with moderate-to-severe atopic dermatitis (AD) before and after 16 weeks of dupilumab treatment, revealing significant changes in immune pathways.

Two specific genes, MAP2K3 and UBE2L3, were identified as potential predictors of dupilumab efficacy, suggesting that they could help determine which patients are likely to benefit from this treatment.

In a study of 60 patients with atopic dermatitis treated with dupilumab, serum TARC and LDH levels were strongly associated with changes in disease activity, indicating their potential as effective markers for monitoring treatment response.

The study highlights that the relevance of laboratory markers, such as IgE and eosinophil counts, varies depending on the treatment used, suggesting that dupilumab alters the relationship between these markers and disease activity compared to untreated patients.
