Abstract

Objective: There are limited data on therapy selection and switching in psoriatic arthritis (PsA). This 18 country, real-world study assessed use and switching of immunomodulatory therapy (biologic/apremilast), the extent of treatment failure and its association with reduced physical functioning, health-related quality of life (HRQoL), and work productivity and activity impairment (WPAI). Methods: PsA patients under routine care and their treating physicians provided demographics, current therapy, reasons for switching, duration of first therapy, HRQoL, HAQ-DI, and WPAI. Current immunomodulatory therapy was determined as “failing” if, after ≥ 3 months, physician-rated disease severity had worsened, remained severe, was “unstable/deteriorating,” or they were dissatisfied with disease control and/or did not consider treatment a “success.” Results: Included were 3714 PsA patients; 1455 (40.6%) had never received immunomodulatory therapy; 1796 (50.1%) had ever received 1 immunomodulatory therapy and 331 (9.2%) ≥ 1. Lack of efficacy with first immunomodulatory therapy was the most common reason for switching; patients whose physicians indicated “primary lack of efficacy” as the reason, switched after a mean of 9.4 months. Patients currently failing immunomodulator therapies (n = 246) had poorer HRQoL compared with treatment success (n = 1472) measured by EQ-5D-3L (0.60 vs 0.77%; P < 0.0001); SF-36 PCS (40.8% vs 46.1%; P < 0.0001) MCS (41.1% vs 45.3%; P < 0.0001). Physical functioning, activity, and work productivity were also more impaired (HAQ-DI: 0.88 vs 0.56; activity impairment: 46.7% vs 29.7%; overall work impairment: 35.4% vs 26.1%; all P < 0.0001). Conclusions: Poor treatment response in PsA is associated with substantial negative patient impact. In cases of primary treatment failure, timely switching is needed.
