Combination use of systemic therapies in psoriasis: Baseline characteristics from the Corrona Psoriasis Registry

Background: For patients with moderate to severe psoriasis or psoriatic arthritis, systemic monotherapy can be insufficient in attaining the desired level of control. As such, combination therapies are frequently used in difficult cases. The aim of this study was to analyze the baseline characteristics of patients who require combination therapy using preliminary data from the Corrona Psoriasis Registry.
