It has previously been shown that the survival of anti-TNF drugs was lower in Rheumatoid arthritis (RA) than in other chronic arthritis1. The objective of this study was to investigate the drug retention of Golimumab (GOL) and its effectiveness in patients affected with axial Spondyloarthritis (AxSpA), Psoriatic arthritis (PsA) and RA. Furthermore, the impact of possible baseline predictors was also evaluated.
This is a multicenter prospective observational study of unselected patients with AxSpA, PsA and RA starting GOL because of their active disease despite prior treatment with conventional disease modifying drugs (DMARDs) or biological DMARDs (bDMARDs) in the settings of standard care from 11 rheumatologic centres of Apulia (Southern Italy). The primary endpoint was GOL drug retention at 2 years. A secondary endpoint was clinical outcomes based on DAS28 and BASDAI reduction. Time to discontinuation was defined as the time between drug initiation and last administration plus one dispensation interval. Kaplan-Meier curve analysis was used to assess drug retention, and a Cox proportional regression model, adjusting for potential confounders, including prior bDMARD exposure, patient demographics and disease characteristics, for the analysis of predictors.
Results: To date, 357 patients (PsA 154, AR 80, AxSpA 123) have been enrolled, 151 (42.3%) were “biologic-naïve”. Disease duration was 6.7 ±6 yrs for PsA, 8.1 ±7 for RA, and 7.0 ±6 for AxSpA, respectively. At 2 years (Fig.1), the crude survival rate was 74.8% (21.1 ± 0.5 months) for AxSpa, 67.5% (20.2 ± 0.8 months) for RA and 63.6% (18.8 ± 0.6 months) for PsA, being the difference not statistically significant. Analysis of predictors showed that female gender strongly correlated with GOL discontinuation (hazard ratio (HR) (95% CI): 3.82, (1.54-9.51)), while the lack of extra-articular manifestations was a negative predictor (HR (95% CI): 0.21, (0.49-0.91) for AxSpA patients. No predictors of drug survival for RA and PsA were found. Additionally, GOL was effective in all patients with a significant reduction of DAS28 and BASDAI at 12 and 24 months compared to baseline (Table 1).
Unlike previous studies on TNF inhibitors, GOL seems to have similar drug survival in different chronic arthritides regardless of prior bDMARD treatment. Female AxSpA patients with extra-articular manifestations have higher hazard to discontinue the therapy .
