Abstract
Introduction: This study aimed to report bimekizumab (BKZ) efficacy and safety in Japanese patients with generalised pustular psoriasis (GPP) and erythrodermic psoriasis (EP).
Methods: Patients aged ≥ 18 years with plaque psoriasis, GPP, or EP received BKZ for 144 weeks; only results for GPP and EP reported here. All patients received BKZ 320 mg every 4 weeks (Q4W) at week 0, with dose adjustments for Q4W or Q8W at weeks 16 and 48, depending on Investigator's Global Assessment (IGA) 0/1 response. Efficacy outcomes assessed to week 144: IGA 0/1, Dermatology Life Quality Index (DLQI) 0/1, Clinical Global Impressions-Improvement (CGI-I), ≥ 75/90/100% improvement from baseline Psoriasis Area and Severity Index (PASI 75/90/100), ≥ 75/90/100% improvement from baseline modified Nail Psoriasis Severity Index (mNAPSI 75/90/100), and patient-reported outcomes; GPP-specific outcomes: Japanese Dermatological Association (JDA) severity index and Global Improvement Score (GIS). Treatment emergent adverse events (TEAEs) evaluated through weeks 0-144 and safety follow-up.
Results: At week 144, most patients with GPP (8/10) and EP (10/11) completed the study. At week 16, all patients reported efficacy outcomes improving with BKZ, generally persisting through week 144. At week 144 (missing visit: 1 GPP), 6/7 patients with GPP and 8/10 with EP achieved IGA 0/1; 5/7 and 9/10 patients achieved DLQI 0/1; 7/7 and 9/10 patients achieved CGI-I response ("improved"/"remission"); and 6/7 and 9/10 patients achieved PASI 90, respectively; 2/5 patients with GPP and 4/9 with EP achieved week 144 mNAPSI 100. Among patients with GPP, JDA severity index generally decreased and improvements in GIS were sustained to week 144. Serious TEAEs were observed in 2/10 patients with GPP and 5/11 with EP; BKZ was well tolerated with low incidence of TEAEs leading to study discontinuation (2 GPP, 1 EP).
Conclusions: Long-term BKZ treatment over 3 years improved signs and symptoms of GPP and EP; these were sustained through week 144. No new safety signals were identified.
期刊介绍：
Dermatology and Therapy is an international, open access, peer-reviewed, rapid publication journal (peer review in 2 weeks, published 3–4 weeks from acceptance). The journal is dedicated to the publication of high-quality clinical (all phases), observational, real-world, and health outcomes research around the discovery, development, and use of dermatological therapies. Studies relating to diagnosis, pharmacoeconomics, public health and epidemiology, quality of life, and patient care, management, and education are also encouraged.
Areas of focus include, but are not limited to all clinical aspects of dermatology, such as skin pharmacology; skin development and aging; prevention, diagnosis, and management of skin disorders and melanomas; research into dermal structures and pathology; and all areas of aesthetic dermatology, including skin maintenance, dermatological surgery, and lasers.
The journal is of interest to a broad audience of pharmaceutical and healthcare professionals and publishes original research, reviews, case reports/case series, trial protocols, and short communications. Dermatology and Therapy will consider all scientifically sound research be it positive, confirmatory or negative data. Submissions are welcomed whether they relate to an International and/or a country-specific audience, something that is crucially important when researchers are trying to target more specific patient populations. This inclusive approach allows the journal to assist in the dissemination of quality research, which may be considered of insufficient interest by other journals. The journal appeals to a global audience and receives submissions from all over the world.
