N2 - PURPOSE: Psoriasis (PsO), a chronic inflammatory skin disorder affecting a substantial proportion of populations globally, often necessitates systemic treatment including biologics. This 14-year cohort study, based on Danish national register data, aimed to investigate the enduring safety profile of ustekinumab compared to other systemic psoriasis treatments.METHODS: Using comprehensive Danish national register data, this study scrutinized patients diagnosed with psoriasis or psoriatic arthritis (PsA) who received ustekinumab. The treatment group comparators were non-biological systemic treatment (non-biologic), tumor necrosis factor α inhibitor medicine groups (TNF-α), interleukin (IL)-17 inhibitors (IL-17), and IL-23 inhibitors (IL-23). The study periods for comparisons were 2009-2022 for non-biologic and TNF-α, 2015-2022 for IL-17, and 2018-2022 for IL-23. Outcomes were malignancies, cardiovascular events, serious infections, and serious hypersensitivity reactions. Cox proportional hazards regression models were employed to analyze two estimands: a standard intention-to-treat (ITT) estimand and a continuous-index-treatment (CIT) estimand, which considered switch and re-initiation of treatments within individuals.RESULTS: Users of ustekinumab were found to be younger on average, with an average age of 45.1 years compared to 51.6, 47.2, 49.0, and 48.4 years in the non-biologic, TNF-α, IL-17, and IL-23 groups, respectively. Also, 57.3% of the ustekinumab users were male, compared to 46.7%, 48.9%, 50.9%, and 58.3% for the non-biologic, TNF-α, IL-17, and IL-23 groups, respectively. Although the hazard ratio estimates varied across comparators, ustekinumab was found to be safe: regardless of PsA status, no discernible safety signals in terms of malignancy, MACE, severe infections, or severe hypersensitivity reactions were observed for ustekinumab when compared to the treatment comparators.CONCLUSIONS: The present study corroborated the enduring safety of ustekinumab in the context of PsO treatment.
