Randomized Controlled Trial Multicenter Study
Efficacy and safety of brodalumab in the Korean population for the treatment of moderate to severe plaque psoriasis: A randomized, phase III, double-blind, placebo-controlled study.
Psoriasis, a chronic inflammatory skin disease, negatively impacts patients' quality of life (QoL). This randomized, phase III, double-blind, placebo-controlled, multicenter study evaluated the efficacy and safety of brodalumab, a human anti-interleukin-17 receptor A monoclonal antibody, in Korean patients with moderate to severe plaque psoriasis. Coprimary end-points were the percentage of patients with 75% or more improvement in Psoriasis Area and Severity Index (PASI 75) and static Physician's Global Assessment (sPGA) success (score 0/1) at week 12. ⋯ Brodalumab treatment rapidly improved DLQI scores. The most common treatment-emergent adverse events were nasopharyngitis, upper respiratory tract infections, tinea pedis, and urticaria. Overall, treatment with brodalumab 210 mg Q2W resulted in a rapid and significant clinical benefit and was well tolerated in patients with moderate to severe plaque psoriasis in Korea.

Randomized Controlled Trial
Efficacy and tolerability of low-dose spironolactone and topical benzoyl peroxide in adult female acne: A randomized, double-blind, placebo-controlled trial.
Effective therapies for adult female acne (AFA) are limited. Oral spironolactone (SPL), 100-200 mg/day, is currently used off-label to treat AFA. However, high-dose SPL results in clinically significant side-effects which prevent widespread use in clinical practice. ⋯ A small number of participants in SPL25 and SPL50 reported mild and temporary TRAE, such as menstrual irregularities, breast tenderness and dizziness. The combination of SPL 50 mg/day and topical BP proved effective in improving moderate AFA in Thai women, with an acceptable side-effect profile. We propose this regimen as an option for treating moderate AFA.

Randomized Controlled Trial
Efficacy and safety of risankizumab in Japanese patients with moderate to severe plaque psoriasis: Results from the SustaIMM phase 2/3 trial.
Risankizumab, a humanized immunoglobulin G1 monoclonal antibody, selectively inhibits interleukin-23, a key cytokine in the pathogenesis of psoriasis, by binding to its p19 subunit. In SustaIMM (ClinicalTrials.gov/NCT03000075), a phase 2/3, double-blinded, placebo-controlled study, Japanese patients with moderate to severe plaque psoriasis (n = 171) were stratified by bodyweight and concomitant psoriatic arthritis and randomized 2:2:1:1 to 75 mg risankizumab, 150 mg risankizumab, placebo with cross-over to 75 mg risankizumab and placebo with cross-over to 150 mg risankizumab. Dosing was at weeks 0, 4, 16, 28 and 40, with placebo cross-over to risankizumab at week 16. ⋯ Through week 52, PASI and sPGA responses increased or were maintained and treatment-emergent adverse events were comparable across treatment groups. Both doses of risankizumab were superior to placebo in treating patients with moderate to severe plaque psoriasis. The safety profile was consistent with previous risankizumab trials, with no new or unexpected safety findings.

Randomized Controlled Trial
Nemolizumab in moderate to severe atopic dermatitis: An exploratory analysis of work productivity and activity impairment in a randomized phase II study.
Atopic dermatitis negatively impacts work productivity. This study investigated the impact of nemolizumab on work productivity and activity impairment in adults with moderate to severe atopic dermatitis inadequately controlled by topical treatments in a two-part, phase II, randomized control trial. The Work Productivity and Activity Impairment - Atopic Dermatitis questionnaire was an exploratory end-point. ⋯ At week 12, patients receiving nemolizumab every 4 weeks showed greater mean (standard error) Work Productivity and Activity Impairment - Atopic Dermatitis improvement (score reduction) from baseline versus placebo: Percent Work Time Missed (0.1, 0.5 or 2.0 mg/kg vs placebo): -4.0% (3.9%), -1.7% (4.2%) and -1.6% (4.2%) versus 4.9% (4.5%); Percent Impairment While Working, -15.8% (6.0%), -24.1% (6.5%) and -34.3% (6.4%) versus -16.5% (7.1%); Percent Overall Work Impairment, -16.3% (6.0%), -23.1% (6.5%) and -34.5% (6.3%) versus -16.6% (7.1%); and Percent Activity Impairment, -13.4% (5.3%), -23.5% (5.3%) and -41.9% (5.5%) versus -10.9% (5.7%). Improvements were sustained through week 64. Nemolizumab-treated patients with moderate to severe atopic dermatitis reported improvements in Work Productivity and Activity Impairment through week 64.

Randomized Controlled Trial Multicenter Study
Efficacy and safety of secukinumab in Taiwanese patients with moderate to severe plaque psoriasis: Subanalysis from ERASURE phase III study.
The efficacy and safety of secukinumab, a fully human anti-interleukin-17A monoclonal antibody, has been evaluated for moderate to severe plaque psoriasis in global trials which have included a low proportion of Asian subjects. We analyzed the efficacy and safety of secukinumab in Taiwanese patients in a phase III global clinical trial (ERASURE). Fifty-one Taiwanese patients were randomized into s.c. placebo, 150 and 300 mg secukinumab treatment groups. ⋯ The most common AE (cases/per 100 patient-year) during the entire treatment period were upper respiratory tract infection and pruritus. The duration of upper respiratory tract infection per 100 patient-year was approximately 399 days in placebo, 1261 days in 150 mg secukinumab and 1805 days in 300 mg secukinumab. The safety and efficacy of secukinumab in Taiwanese patients was compatible with the global phase III study in the treatment of moderate to severe plaque psoriasis.
