Abstract

Introduction: Psoriasis, a chronic inflammatory skin disease, affects approximately one million Canadians, with plaque psoriasis (PsO) being the most common subtype. While brodalumab has shown efficacy and safety in phase III clinical trials, Canadian real-world evidence remains limited. This retrospective cohort study aims to report on the real-world outcomes of Canadian patients with PsO who initiated treatment with brodalumab within the 4-year period following its approval by Health Canada.

Methods: Data from patients with PsO initiating brodalumab treatment in the Canadian patient support program between July 1, 2018 and June 30, 2022 were analyzed. The primary objective evaluated the proportion of patients achieving a 100% reduction in the Psoriasis Area and Severity Index (PASI 100) at selected time windows. Secondary and exploratory objectives included assessing the 90% reduction in PASI score (PASI 90), changes from baseline in mean PASI, body surface area (BSA), and Dermatology Life Quality Index (DLQI) scores, as well as treatment persistence.

Results: A total of 2482 patients (58.5% male; mean age 51.0 years) were included, with over half being biologic-naïve (56.9%). In a subset of patients with baseline and at least one follow-up data, 66.1% and 53.2% achieved PASI 90 and PASI 100, respectively, within the first 3 months. These rates were sustained, with 68.1% and 52.2% achieving PASI 90 and PASI 100, respectively, beyond 24 months. Significant improvements from baseline were observed for PASI, BSA, and DLQI scores, and these improvements were maintained over time. Among all patients, the 1-year persistence rate was 73.4%.

Conclusions: This study provides valuable insights into the profile of patients treated with brodalumab in Canada. While the rapid and sustained skin clearance, as well as improvements in PASI, BSA, and DLQI scores, support the therapeutic benefits of brodalumab beyond clinical trials, further research on long-term effectiveness and safety is warranted.

Brodalumab在加拿大现实世界环境中治疗斑块性银屑病：长达4年的回顾性队列分析。

银屑病是一种慢性炎症性皮肤病，影响了大约100万加拿大人，其中斑块型银屑病（PsO）是最常见的亚型。虽然brodalumab在III期临床试验中显示出有效性和安全性，但加拿大的实际证据仍然有限。这项回顾性队列研究旨在报告在加拿大卫生部批准使用brodalumab后的4年期间内，加拿大PsO患者开始接受治疗的实际结果。方法：分析2018年7月1日至2022年6月30日在加拿大患者支持计划中启动brodalumab治疗的PsO患者的数据。主要目的是评估在选定的时间窗内实现银屑病面积和严重程度指数（PASI 100） 100%减少的患者比例。次要和探索性目标包括评估PASI评分（PASI 90）降低90%，平均PASI，体表面积（BSA）和皮肤病生活质量指数（DLQI）评分从基线的变化，以及治疗持久性。结果：共2482例患者，其中男性58.5%；平均年龄51.0岁)，一半以上为biologic-naïve（56.9%）。在基线和至少一次随访数据的患者亚组中，66.1%和53.2%分别在前3个月内达到PASI 90和PASI 100。这些比率持续了24个月，分别有68.1%和52.2%的患者达到了PASI 90和PASI 100。PASI、BSA和DLQI评分较基线有显著改善，且这些改善持续一段时间。在所有患者中，1年持续率为73.4%。结论：这项研究为加拿大接受brodalumab治疗的患者提供了有价值的见解。虽然快速和持续的皮肤清除率，以及PASI、BSA和DLQI评分的改善，支持了brodalumab在临床试验之外的治疗益处，但需要进一步研究其长期有效性和安全性。

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.
