This retrospective observational study conducted in Sweden from 2010 to 2018 analyzed 2292 adults with psoriasis who were treated with biologics. The study revealed that despite the chronic nature of psoriasis, the persistence with biologics was relatively low. Changes in therapeutic landscape influenced the persistence over time, providing patients with more options to switch biologic treatments.
Introduction Biologic treatments for psoriasis are commonly switched. Treatment persistence represents an important parameter related to long-term therapeutic performance. The objective of the study was to analyse the real-world persistence with biologics over time in the treatment of psoriasis. Methods A retrospective observational study of adults with psoriasis was conducted based on Swedish national registry data from 2010 to 2018. Patients included were treated with a biologic between 2010 and 2018. Treatment episodes were identified from the drug's date of dispensation recorded in the Prescribed Drug Register to the end of supply of the drug. Median persistence was estimated by Kaplan-Meier survival curves for patients who received adalimumab, etanercept, secukinumab, ustekinumab and ixekizumab. Descriptive analysis of change in persistence over time for 3-year running cohorts was also carried out. Results A total of 2292 patients were analysed. Patients who received ustekinumab had the longest median persistence [49.3 months, 95% confidence interval (CI) 38.0-59.1] and etanercept the shortest (16.3 months, 95% CI 14.5-19.0). Median persistence was longer in biologic-naive than biologic-exposed patients. Persistence for ustekinumab decreased by almost 50% over the study period, from a median of 62.3 (95% CI 45.6-infinity) months in 2010-2011 to 32.7 (21.2-49.3) months in 2014-2016. Conclusions Persistence with biologics was, on average, relatively low, given the chronic nature of psoriasis. Changes in persistence over time seemed to be attributable to changes in the therapeutic landscape, providing patients with more options to switch biologic treatments if their current management was considered suboptimal.
