Abstract
Background Retention of biological treatment provides a marker of drug effectiveness and patient satisfaction. Retention of golimumab was high in clinical trial extensions and real-world studies up to 5 years in patients with immune-mediated rheumatic diseases. Objective To assess the probability of real-world long-term retention of treatment with golimumab up to 7 years after treatment initiation. Methods This retrospective noninterventional study involved analysis of the Spanish biological drugs registry, BIOBADASER. Adults who had ever received golimumab for rheumatoid arthritis (RA), axial spondyloarthritis (SpA), or psoriatic arthritis (PsA), and had initiated it > 6 months before the analysis date, were included. Results Among 685 patients (28.5% RA, 42.9% SpA, 28.6% PsA), the overall probability of retention of golimumab treatment since initiation was 71.7% (95% confidence interval 68.1–74.9) at year 1, 60.5% (56.5–64.2%) at year 2, 55.6% (51.5–59.5%) at year 3, 50.6% (46.2–54.8%) at year 4, 45.1% (40.1–50.0%) at year 5, 44.2% (39.0–49.3) at year 6, and 39.5% (32.8–46.2) at year 7. Retention was greater in patients with axial SpA or PsA versus RA (p < 0.001) and when golimumab was used as first-line treatment versus third or later lines (p < 0.001). Factors associated with greater golimumab retention in Cox regression included use as first-line biological therapy, having axial SpA or PsA rather than RA, and concomitant methotrexate therapy. Steroids were associated with lower retention. Conclusion In this real-world study of RA, axial SpA, and PsA patients, the retention rate of golimumab was 39.5% at year 7. Key Points • Retention of biological treatment provides a marker of drug effectiveness and patient satisfaction. • This real-world study of 685 patients with rheumatoid arthritis (RA), axial spondyloarthritis (SpA), or psoriatic arthritis (PsA) showed that golimumab treatment had a retention rate up to 39.5% at year 7. • Greater golimumab retention was associated with use as first-line biological therapy, having axial SpA or PsA rather than RA, and concomitant methotrexate therapyKeywords
