Background: Golimumab ( GLM ) is the latest anti-TNFα to be indicated for treating rheumatoid arthritis ( RA ), psoriatic arthritis ( PsA ) and axial spondyloarthritis ( axSpA ). The GO-PRACTICE study was performed in France at the request of the French Health Authorities, for the reevaluation of GLM in real-life.
Objectives: The primary objective was to estimate GLM persistence at 2 years from initial prescription. This abstract focuses on a post-hoc analysis of the factors linked to GLM discontinuation in axSpA patients.
Methods: Observational, prospective, multicenter study, that consecutively recruited adult patients with RA, PsA and axSpA who were newly prescribed GLM. Patients were followed-up for 2 years and outcomes data were collected at baseline ( BL ), 1 and 2 years. Patients’ sociodemographic characteristics, disease history, comorbidities and treatment history were also collected at BL. Persistence was estimated with the Kaplan-Meier method. Cox proportional hazard models were used to assess factors associated with persistence. Selected BL characteristics were studied in univariate models, where those associated with p -value <0.20 were included in multivariate analysis. Significance level was set at p <0.05.
Results: 478 patients with axSpA were included from Jan 2015 to Mar 2016. Mean age was 43 years and 55% were female; 61% of patients were biologic-naïve (BN, n=291) and 39% (n=187) were biologic-pretreated (BP). Median time-elapsed in years since axSpA diagnosis was 1.7 (range 0–45.1) and 6.9 (range 0.2–51.8) in BN and BP patients, respectively ( P <0.001); 97% patients were prescribed 50 mg GLM monthly and co-treatments included DMARD (34%), corticosteroids (17%) and NSAIDs/analgesics (90%).
Cumulative persistence probability of GLM at 2-years was 52.6% (

Conclusion: 2-year GLM persistence in axSpA patients was 52.6%. Females and those who were biologics-pretreated were at greater risk for discontinuing GLM before 2 years.
