Long-Term Efficacy, Safety and Drug Survival of Ustekinumab in a Spanish Cohort of Patients with Moderate to Severe Plaque Psoriasis

Abstract

Objective: To investigate the efficacy and safety of ustekinumab in clinical practice and the influence of several variables on response rates as well as on drug survival. Methods: Retrospectively collected efficacy and safety data of a cohort of 67 consecutive patients treated with ustekinumab for moderate to severe psoriasis for at least 28 weeks and a maximum of 3 years. Drug survival was analyzed by the Kaplan-Meier method with log-rank test. Results: PASI75 response rates were numerically higher in patients treated with 45 mg and patients naïve to tumor necrosis factor (TNF)-blocking agents, at all time points. Drug survival was not significantly affected by any variable. Conclusion: Male sex, weight >100 kg, obesity, and previous failure of one or more TNF inhibitors were associated with a diminished response to treatment. Obesity or previous exposure to anti-TNF agents was not associated with a diminished drug survival in this Spanish cohort.
