Abstract
Introduction: Tildrakizumab is an anti-interleukin-23 p19 monoclonal antibody approved in several countries to treat adult patients with moderate-to-severe plaque psoriasis who are candidates for phototherapy or systemic therapy. Limited data are available on tildrakizumab treatment patterns in clinical practice. The Canadian tildrakizumab patient support program (PSP), which provides personalized reimbursement, financial aid, and injection training support for disease management, was used in this study to evaluate real-world persistence and adherence to tildrakizumab.
Methods: This retrospective, observational study used data collected in the Canadian tildrakizumab PSP database between August 4, 2021, and August 1, 2023. Adult (≥18 years) patients with moderate-to-severe plaque psoriasis who enrolled in the PSP and received ≥6 months of treatment with tildrakizumab before August 1, 2023, were included. Data up to Week 52 following treatment initiation were analyzed. Persistence was defined as the number of days until treatment discontinuation. Adherence was measured as the proportion of days covered (PDC) from treatment initiation to treatment discontinuation or study cutoff, with PDC ≥80% indicating high adherence.
Results: The study included 813 patients with a mean ± standard deviation (SD) age of 49.6 ± 15.9 years; 55.0% (447/813) were male, and 92.7% (754/813) were biologic-naïve when initiating tildrakizumab. Patients received tildrakizumab treatment for a mean ± SD of 329.6 ± 55.0 days. After 1 year, 88.0% of patients were persistent on treatment. Adherence was also high, with mean ± SD PDC being 97.5% ± 8.9% and 93.5% of patients having PDC ≥80%. Eighty-five patients discontinued treatment, primarily because of switching to other therapies. Common adverse outcomes included treatment misuse (18.9%), disease flare (8.2%), and treatment discontinuation (7.4%).
Conclusion: Persistence and adherence to tildrakizumab were high through 52 weeks of treatment among patients with moderate-to-severe plaque psoriasis enrolled in the Canadian PSP.
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.
