Real-life golimumab persitence in patients with axial spondyloarthritis: post-hoc results of the prospective observational cohort study, GO-PRACTICE.

OBJECTIVES: To evaluate in clinical practice the persistence and safety of golimumab, together with the evolution of disease activity and patient reported outcomes, in adult patients with rheumatoid arthritis, psoriatic arthritis and axial spondyloarthritis (axSpA). This article focuses on the outcomes of golimumab treatment in axSpA patients. METHODS: Golimumab persistence 24 months after initial prescription (primary outcome) was assessed using Kaplan-Meier estimates. Secondary outcomes included evaluations of disease activity evolution (ASDAS and BASDAI), patient-reported outcomes (EQ-5D, SF-12 and HAQ), and golimumab's safety profile. RESULTS: Of 478 axSpA patients, 60.9% were biologic-naïve. Mean age and proportion of females were higher in biologics-pretreated patients (46.8 vs. 40.2 years, p<0.001 and 62.0% vs. 49.8%, p=0.009, respectively). Golimumab persistence at 24 months was 52.6% [95% CI 47.9-57.1%] in the axSpA cohort. It was 59.2% [95% CI 53.1-64.8%] and 42.7% [95% CI 35.3-49.8%] respectively, for biologics-naïve and biologics-pretreated patients (p<0.01), and 65.9% [95% CI 58.9-72.0%] and 41.5% [95% CI 35.2-47.6%], respectively for males and females (p<0.01). Reasons for golimumab discontinuation were primary non-response (37.4%), secondary non-response (24.8%) and intolerance (21.5%). Disease activity and patient reported outcomes improved significantly for those who persisted at 24 months and were higher for biologics-naïve patients. CONCLUSIONS: Golimumab persistence at 2 years in axSpA patients was 52.6%. Previous treatment with another biologic and female gender were associated with earlier discontinuation. Golimumab was a well-tolerated therapy for axSpA, with no new safety signals observed.

Real-life persistence of golimumab in patients with chronic inflammatory rheumatic diseases: results of the 2-year observational GO-PRACTICE study.

OBJECTIVES: GO-PRACTICE aimed to evaluate the persistence, clinical response and safety of golimumab in adult patients with chronic inflammatory rheumatic disease. METHODS: Prospective observational study with 24 months of follow-up, involving 134 rheumatologists from public or private health establishments in France. The primary outcome was the persistence of golimumab 24 months after initial prescription. Cumulative persistence probabilities were determined from Kaplan-Meier estimates. Secondary outcomes included an evaluation of disease activity and golimumab safety profile. RESULTS: Of 754 consecutively recruited patients, 170 had rheumatoid arthritis (RA) (54.3 years, 74.1% female, 64.7% biologics-naïve), 106 had psoriatic arthritis (PsA) (48.1 years, 70% female, 66.0% biologics-naïve) and 478 had axial spondyloarthritis (axSpA) (42.8 years, 54.6% female, 60.9% biologics-naïve). Golimumab persistence at 2 years was 56.5%, 45.1% and 52.6%, respectively, in RA, PsA and axSpA groups. Persistence was higher in biologics-naïve (58.3%) than in biologics pre-treated patients (42.7%, p<0.01). For 362 patients continuing golimumab at 2 years, disease activity improved significantly from baseline to 2 years: mean 28-joint disease activity score for RA and PsA was lowered by 2.06 and 1.89 points, and mean ankylosing spondylitis disease activity score was lowered by 3.11 points (p<0.0001) for axSpA. Patient appreciation of disease activity also improved; 8.9% of discontinuations were due to intolerance. CONCLUSIONS: Golimumab persistence was satisfactory at 2 years and accompanied by improvements in clinical effectiveness in 362 patients continuing golimumab at 2 years. Golimumab was well tolerated and its safety profile was consistent with those reported in previous studies.
