Enhanced Effectiveness of Adalimumab Compared to Topical/Traditional Systemic Agents in the Treatment of Moderate to Severe Plaque Psoriasis: Results from a Canadian Observational Epidemiologic Study (COMPLETE-PS).

INTRODUCTION: Real-world evidence is important for post-marketing evaluation. Data comparing adalimumab's effectiveness and safety with traditional therapies in clinical settings are currently lacking. The aim of this study was to compare real-world effectiveness of adalimumab versus topical/traditional systemic agents for management of moderate to severe plaque psoriasis METHODS: Patients requiring change in treatment were enrolled between 2011 and 2016 and followed per routine care for up to 24 months. Achievement of Physician Global Assessment (PGA) ≤ 1.0 at 6 months was assessed with logistic regression; time to achievement was assessed using Cox regression. Additional outcomes were assessed using repeated measures mixed models.

RESULTS: Patients receiving adalimumab (n = 293) versus topical/traditional systemic agents (n = 302) were more likely to achieve PGA ≤ 1.0 at 6 months (odds ratio 2.37, 95% confidence interval [CI] 1.31-4.30) in a shorter time (hazard ratio 2.14, 95% CI 1.53-3.00), reporting both lower body surface area and improved quality of life and work productivity.

CONCLUSION: In this real-world study, adalimumab was more effective than topical/traditional systemic agents at reducing disease activity and improving quality of life outcomes among Canadians with moderate to severe plaque psoriasis. (NCT00799877).
