Eligible patients (N = 121) were randomized 1:1:1 to receive tapinarof cream 0.

Long-term (68 weeks) administration of nemolizumab in paediatric patients aged 6-12 years with atopic dermatitis with moderate-to-severe pruritus: efficacy and safety data from a phase III study.

Background: A phase III clinical trial in Japanese children aged 6-12 years with atopic dermatitis (AD) and inadequately controlled moderate-to-severe pruritus found that 16 weeks of nemolizumab treatment (30 mg every 4 weeks [Q4W]) was clinically effective and tolerable, with early improvement in pruritus and associated skin signs and a positive impact on patient quality of life (QoL).

Objective: To report the findings from the long-term extension period of the study, and evaluate the efficacy and safety profiles of nemolizumab when administered concomitantly with topical agents over 68 weeks.

Methods: The study included a 16-week, randomized, placebo-controlled, double-blind, parallel-group period during which patients received nemolizumab 30 mg or placebo Q4W; those who completed this period could enter a 52-week, long-term treatment period during which all patients received nemolizumab Q4W.

English version of Japanese guidance for the use of oral Janus kinase inhibitors (JAK1 and TYK2 inhibitors) in the treatments of psoriasis.

This is the English version of Japanese guidance for the use of oral Janus kinase (JAK) inhibitors (JAK1 and tyrosine kinase 2 [TYK2] inhibitors) in the treatments of psoriasis. Several cytokines, such as interleukin (IL)-6, IL-7, IL-12, IL-21, IL-22, IL-23, interferon (IFN)-α, and IFN-γ, are involved in the pathogenesis of psoriasis (including psoriatic arthritis). As oral JAK inhibitors hinder the JAK-signal transducers and activators of transcription signal transduction routes involved in the signal transduction of these cytokines, they may be effective for the treatment of psoriasis.

Pharmacokinetics, pharmacodynamics, and exposure-efficacy of dupilumab in adults with atopic dermatitis.

The pharmacokinetics (PKs) and exposure-efficacy of dupilumab have not been fully described for adults with atopic dermatitis (AD). Our objectives were to analyze the PKs and exposure-efficacy of dupilumab in adults with AD and compare the results of Japanese and overall populations. Adults with moderate-to-severe AD were randomly assigned to dupilumab (300 mg weekly [qw] or every 2 weeks [q2w], 200 mg q2w, 300 mg every 4 weeks [q4w], or 100 mg q4w) or placebo for 16 weeks in a randomized, double-blind, placebo-controlled, dose-ranging phase IIb trial (NCT01859988).

A Systematic Literature Review of Economic Evaluations and Cost Studies of the Treatment of Psoriasis, Atopic Dermatitis, and Chronic Urticaria.

Introduction: Psoriasis (PSO), atopic dermatitis (AD), and chronic urticaria (CU) are common manifestations of immunological skin and subcutaneous conditions and have been shown to have a substantial impact on the quality of life of patients. The cost of treating those conditions can also be high, as the use of biologic treatments has become more common for moderate to severe patients. In this review, we examine characteristics of economic evaluations and cost studies conducted for the three conditions.
