Abstract
OBJECTIVE: To compare (1) golimumab drug survival and efficacy in bDMARD naïve compared with non-naïve rheumatoid arthritis (RA), psoriatic arthritis (PsA) and axial spondyloarthritis (ax-SpA) patients, (2) golimumab drug survival in RA and PsA patients treated with/without concomitant csDMARDs, (3) predictors of golimumab drug discontinuation. METHODS: Patients starting golimumab were included from the prospective observational multicenter Norwegian DMARD study. Drug survival was explored by Kaplan-Meier analyses with log rank test. Treatment responses were compared using ANCOVA. Univariate and multivariate Cox regression analyses were performed to identify predictors of golimumab discontinuation. RESULTS: We included 808 patients (163 RA, 266 PsA, 379 ax-SpA). Golimumab drug survival after 1/2/4 years were not significantly different between bDMARD naïve and non-naïve patients (all, p ≥ 0.12; RA, p ≥ 0.07; PsA, p ≥ 0.28; ax-SpA, p ≥ 0.61), nor between RA (p ≥ 0.10) and PsA (p ≥ 0.07) patients treated with vs. without csDMARD comedication. bDMARD naïve compared with non-naïve ax-SpA patients had better 3-month ASDAS/BASDAI/MHAQ responses (p ≤ 0.02). bDMARD naïve compared with non-naïve RA and PsA patients had a trend towards better treatment responses. Identified predictors of 4-year golimumab discontinuation were patient's global and female gender in patients overall and in subgroups of PsA and ax-SpA patients, and patient's global and CRP in RA. CONCLUSION: Golimumab drug survival was not significantly different between bDMARD naïve and non-naïve RA, PsA and ax-SpA patients, nor between RA and PsA patients treated with vs. without concomitant csDMARDs. Treatment responses were significantly better for bDMARD naïve than non-naïve ax-SpA patients. Identified predictors of golimumab discontinuation were patient's global and female gender in patients overall and in subgroups of PsA and ax-SpA patients, and patient's global and CRP in RA.
