A Study to Evaluate the Efficacy and Safety of Subcutaneous Amlitelimab on Background Topical Corticosteroids Therapy in Participants Aged 12 Years and Older With Moderate-to-severe AD Who Have Had an Inadequate Response to Prior Biologic Therapy or an Oral JAK Inhibitor

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).

Long-Term Safety and Efficacy Evaluation of Amlitelimab in Participants of Previous Amlitelimab Moderate to Severe Atopic Dermatitis Clinical Trials

This is an open-label, Phase 2/Phase 3, long-term extension study for treatment of participants of previous amlitelimab clinical trials in moderate to severe atopic dermatitis. The purpose of this study is to characterize the safety and efficacy of amlitelimab in treated participants with moderate to severe atopic dermatitis (AD) who have previously been enrolled in an amlitelimab clinical trial. All participants will have visits during the treatment period every 4 weeks. Responder participants rolling over from EFC17599 and EFC17600, and responder participants enrolling through screening from DRI17366 will be initiated into drug withdrawal (with no drug administration) at LTS17367 baseline visit to monitor durability of treatment response. If these responder participants relapse during LTS17367, they will have treatment restored. Non-responder participants rolling over from EFC17599 or EFC17600, and non-responder participants enrolling through screening from DRI17366 will have treatment administration from LTS17367 baseline. Participants rolling over from DRI17366, SFY17915 and INT18404 will also have treatment administration from LTS17367 baseline. Remote visits with home dosing are allowed for the purpose of study drug administration, when applicable. In the case of remote visit with home dosing, the participant or a caregiver may administer study drug after appropriate training. Alternatively, if needed, and based on the investigator's judgement, home visits with healthcare professional assistance or on-site study drug administration visits can be performed. Where participants discontinue amlitelimab permanently during LTS17367, safety follow up will be performed for a minimum of 140 days from the last amlitelimab administration.

A Study of Long-term Effect of Dupilumab on Skin Barrier Function in Pediatric Participants With Atopic Dermatitis

This is a 2-year, open-label, exploratory study with a 4-week screening period and a 104-week treatment phase designed to investigate dupilumab's long-term effect on skin barrier function as measured by transepidermal water loss (TEWL) before and after skin tape stripping (STS) in approximately 48 pediatric participants (aged ≥6 and \<15 years at study entry) with moderate-to-severe AD. All eligible participants with AD will be treated with Dupixent® for 104 weeks according to locally approved Dupixent® product label (in country/region where the study is conducted). After the 104-week treatment phase and the last assessment at the End of Treatment (EoT), participants will be followed-up for 4 weeks and an End-of-Study (EoS) visit by telephone at 4 weeks after the EoT visit will end the study for each participant. The maximum duration of the study per participant will be 112 weeks (including screening period). The study population will include approximately 48 pediatric participants with AD for long-term treatment with dupilumab: * Treatment cohort 1 - newly recruited participants with AD (aged ≥6 to \<12 years at study entry) * Treatment cohort 2 - any former PELISTAD participants (from the previous 16-week treatment study \[PELISTAD/LPS16764\] who consent to participate in this long-term study; aged ≥6 to \<15 years at entry to this study)

A Study to Observe How Adolescent Patients With Severe Atopic Dermatitis Despite Less Extensive Skin Lesions (Eczema Area and Severity Index Score < 16) Respond to Dupilumab Treatment

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.
