Dermatitis, Atopic

This is a parallel group, Phase 3, multinational, multicenter, randomized, double-blind, placebo-controlled, 3-arm study for treatment of participants diagnosed with moderate-to-severe AD on background TCS who have had inadequate response to prior biologic or oral JAKi therapy. The purpose of this study is to measure the efficacy and safety of treatment with amlitelimab solution for subcutaneous (SC) injection compared with placebo in participants with moderate-to-severe AD aged 12 years and older on background TCS and have had an inadequate response to prior biologic or an oral JAKi therapy. Study details include: At the end of the treatment period, participants will have the option to enter the Long-Term Safety Study LTS17367 (RIVER-AD). The study duration will be up to 56 weeks for participants not entering the long-term safety study (LTS17367 \[RIVER-AD\]) including a 2 to 4-week screening, a 36-week randomized double-blind period, and a 16-week safety follow-up. The study duration will be up to 40 weeks for participants entering the long-term safety study (LTS17367 \[RIVER-AD\]) including a 2 to 4-week screening and a 36-week randomized double-blind period. The total treatment duration will be up to 36 weeks. The total number of visits will be up to 13 visits (or 12 visits for those entering the long-term safety study LTS17367 \[RIVER-AD\] study).

Background: \- Atopic dermatitis, or eczema, is a chronic skin disorder. Patients sometimes have infections with S. aureus bacteria. Researchers want to study how eczema treatments affect the number and the type of bacteria on the skin. Objectives: \- To study the effect of eczema treatments on skin bacteria. Eligibility: * Individuals between 2 and 25 years of age who have moderate to severe atopic dermatitis. * Healthy volunteers between 18 and 40 years of age with no history of eczema. Design: * Participants will be screened with a physical exam and medical history. Research samples will be collected. Skin biopsies may also be performed. * All participants will be assigned to one of several study groups. * Healthy volunteers must not have taken antibiotics in the year before the start of the study. * All participants will have regular study visits during their 1-year participation. More research samples will be collected at these visits. * Healthy volunteers may be asked to come in for a one-time follow up after the 1 year mark.

In adolescents treated with dupilumab, clinical trials showed significant improvement of atopic dermatitis (AD) signs and symptoms, with a good safety profile. In these clinical trials, only patients with Eczema Area and Severity Index (EASI) score greater than or equal to (≥) 16 were enrolled, and effectiveness on sensitive/visible areas was not specifically evaluated. Further data about the effectiveness of dupilumab in adolescent participants with moderate to mild EASI score and severe itching and/or localized AD are therefore necessary to better understand the potential clinical benefits of dupilumab in these populations. This is an Italian multicenter, 52-week observational (non-interventional) study which will collect data on the characteristics of adolescent (aged 12 to 17 years) participants who suffer from severe AD with EASI score less than (\<) 16, eligible for systemic dupilumab treatment according to Italian reimbursement criteria. It will study the real-world effectiveness and safety of dupilumab in this population, the effect of dupilumab on itching (pruritus), sleep, quality of life and related outcomes, localized AD in sensitive/visible areas, and on coexisting atopic conditions in adolescent participants who receive dupilumab for AD. It will also document dupilumab treatment satisfaction and dupilumab discontinuation in the study participants.

The purpose of this first-in-human (FIH) study is to assess the safety and tolerability, pharmacokinetics (PK), immunogenicity (IG) and pharmacodynamics (PD) of DCY636. The results are intended to support the further clinical development of DCY636 in future studies.

The purpose of this study is to assess how well JNJ-95597528 works compared to placebo in participants with moderate to severe atopic dermatitis (AD).

This is a phase 2b, multicenter, randomized, double-blind, placebo-controlled study.

This is a prospective, multi-center observational study characterizing clinical and patient reported outcomes of patients receiving abrocitinib for moderate-to-severe atopic dermatitis (M2S AD) who had inadequate response (or intolerance) to ≤2 previous biologic therapies approved for M2S AD in the United States. The aim of this study is to measure the effectiveness of abrocitinib in a real-world setting in patients with moderate-to-severe atopic dermatitis, with inadequate response or intolerance to ≤2 biologic therapies.

This is a randomized, double-blind, placebo-controlled, parallel group study to confirm the efficacy and safety of MG-K10 monotherapy in adolescents with moderate-to-severe atopic dermatitis (AD)

This study will compare the efficacy and safety of crisaborole ointment with tacrolimus ointment, in the treatment of patients with mild-to-moderate atopic dermatitis.

The purpose of this non-interventional study is to learn about the safety and effectivness of Cibinqo Tablet for the possible treatment of atopic dermatitis (AD). AD is a long-lasting itchy red rash, caused by a skin reaction. This study is seeking participants who: 1. Are patients with moderate to severe AD who have been waiting to start treatment with Cibinqo 2. Have evidence of a personally signed and dated informed consent document indicating that the patient or their parent(s) or legal guardian, have been informed of all important details of the study Investigators will collect and record the information on each participant's experiences with Cibinqo. This study medicine is a tablet which is taken by mouth. Participants will be observed for about a year. During this time, we will study the experiences of people receiving the study medicine to help us decide if the study medicine is safe and effective.

The primary objective of the study was to evaluate the efficacy of 611 in Chinese Adolescents with moderate to severe atopic dermatitis.

This study is to describe the real-world treatment patterns and clinical outcomes in moderate-to-severe AD patients receiving abrocitinib over a 12-month observation period, and to describe patient demographic and baseline characteristics.

Atopic dermatitis is a common disease affecting millions worldwide. A common associated symptom in this population is pruritus. We seek to investigate the use of an natural, over-the-counter cosmeceutical to help this population

The Spanish Registry of Systemic therapy in atopic eczema, BIOBADATOP, assesses drug safety and treatment effectiveness as well as treatment impact on quality of life in children and adults with atopic eczema receiving systemic immuno-modulatory therapies in Spanish daily practice. The main objectives are: 1. To assess short and long-term safety of systemic therapies (including phototherapy) for atopic eczema (pharmacovigilance). 2. To assess short and long-term effectiveness of systemic therapies, providing a basis for shared decision making and guidelines. Secondary objectives are: 1. To assess short and long-term safety of topical therapies for atopic eczema. 2. To assess effectiveness of different methods of care, including patient training. 3. To describe atopic dermatitis comorbidities.
