Randomized Controlled Trial Multicenter StudyDupilumab improves the molecular signature in skin of patients with moderate-to-severe atopic dermatitis.
Severe atopic dermatitis (AD) has a high unmet need for effective and safe therapeutics. In early-phase trials, dupilumab, a fully human mAb targeting IL-4 receptor α, markedly improved disease activity, but the effect of IL-4/IL-13 blockade on AD at the molecular level has not been characterized. ⋯ This is the first report showing rapid improvement of the AD molecular signature with targeted anti-IL-4 receptor α therapy. These data suggest that IL-4 and IL-13 drive a complex, TH2-centered inflammatory axis in patients with AD.

Randomized Controlled Trial Multicenter StudyEmollient enhancement of the skin barrier from birth offers effective atopic dermatitis prevention.
Atopic dermatitis (atopic eczema) is a chronic inflammatory skin disease that has reached epidemic proportions in children worldwide and is increasing in prevalence. Because of the significant socioeconomic effect of atopic dermatitis and its effect on the quality of life of children and families, there have been decades of research focused on disease prevention, with limited success. Recent advances in cutaneous biology suggest skin barrier defects might be key initiators of atopic dermatitis and possibly allergic sensitization. ⋯ The results of this trial demonstrate that emollient therapy from birth represents a feasible, safe, and effective approach for atopic dermatitis prevention. If confirmed in larger trials, emollient therapy from birth would be a simple and low-cost intervention that could reduce the global burden of allergic diseases.

Randomized Controlled Trial Multicenter Study
Dupilumab treatment in adults with moderate-to-severe atopic dermatitis.
Dupilumab, a fully human monoclonal antibody that blocks interleukin-4 and interleukin-13, has shown efficacy in patients with asthma and elevated eosinophil levels. The blockade by dupilumab of these key drivers of type 2 helper T-cell (Th2)-mediated inflammation could help in the treatment of related diseases, including atopic dermatitis. ⋯ Patients treated with dupilumab had marked and rapid improvement in all the evaluated measures of atopic dermatitis disease activity. Side-effect profiles were not dose-limiting. (Funded by Regeneron Pharmaceuticals and Sanofi; ClinicalTrials.gov numbers, NCT01259323, NCT01385657, NCT01639040, and NCT01548404.).

Randomized Controlled Trial Multicenter Study
Safety and efficacy of topical E6005, a phosphodiesterase 4 inhibitor, in Japanese adult patients with atopic dermatitis: results of a randomized, vehicle-controlled, multicenter clinical trial.
The safety and efficacy of topical E6005, a novel phosphodiesterase 4 inhibitor, in Japanese adults with atopic dermatitis were evaluated. A total of 78 patients were randomized to receive either the 0.2% E6005 ointment or vehicle control (without E6005) at an allocation ratio of 2:1. The randomization phase of 4 weeks was followed by an extension phase of 8 weeks. ⋯ At the end of week 4, Eczema Area and Severity Index (EASI), Severity Scoring Atopic Dermatitis (SCORAD)-objective, SCORAD-C (visual analog scales for pruritus and sleep loss), itch Behavioral Rating Scale, and the severity of the targeted eczematous lesions in the topical E6005 group showed trends toward improvement compared with those in the vehicle group (not statistically significant). However, the group receiving topical E6005 for 12 weeks showed significant score reductions from baselines for EASI (P = 0.030), SCORAD-objective (P < 0.001) and SCORAD-C (P = 0.038). These results further support the development of topical E6005 for the treatment of atopic dermatitis.
