Investigation of the Efficacy and Safety of Xeligekimab (GR1501) in Patients with Moderate-to-Severe Plaque Psoriasis: A Multicenter, Randomized, Double-Blind Phase II Clinical trial.
Introduction: Psoriasis is a chronic inflammatory skin disease. This study evaluated the efficacy and safety of xeligekimab (GR1501), a novel anti-interleukin-17A (anti-IL-17A) monoclonal antibody, in Chinese patients with moderate-to-severe plaque psoriasis.
Methods: In this multicenter, randomized, double-blind, phase II trial, 199 patients were assigned (1:1:1:1) to receive placebo (n = 49) or xeligekimab 100 mg (n = 50), 150 mg (n = 49), or 200 mg (n = 51) every 4 weeks for 12 weeks. All participants then entered a 40-week extension receiving xeligekimab 200 mg every 4 or 8 weeks. The primary endpoint was a 75% reduction in the Psoriasis Area and Severity Index (PASI 75) at week 12. Secondary endpoints included PASI 75, PASI 90 (≥ 90% improvement), and a static Physician's Global Assessment (sPGA) score of 0/1 (clear/almost clear) at week 52. Safety, pharmacokinetics (PK), and anti-drug antibodies (ADA) were also assessed.
Results: At week 12, PASI 75 response rates for the 100, 150, and 200 mg groups were 86.0%, 89.8%, and 88.2%, respectively, versus 2.0% for placebo (P < 0.05). At week 52, PASI 75, PASI 90, and sPGA 0/1 response rates remained high in both 4-week (98.8%, 83.3%, 77.4%) and 8-week (92.9%, 83.3%, 78.6%) groups. No dose-dependent safety issues or ADA positivity were observed.
Conclusion: Xeligekimab demonstrated strong efficacy, sustained response, and favorable safety in patients with moderate-to-severe plaque psoriasis.
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.
