Key clinical point: First-line biologic treatment with tocilizumab significantly reduced disease activity scores and demonstrated a good safety profile in a real-world cohort of patients with rheumatoid arthritis (RA) who had had an inadequate response to disease-modifying antirheumatic drugs (DMARD-IR).
Major finding: At 12 months, tocilizumab treatment led to significant reductions in disease activity scores (all P < .001), with 85.5% of patients receiving tocilizumab achieving remission or low disease activity according to the Disease Activity Score of 28 Joints; however, 22.0% of patients switched to other biologic DMARD either due to inefficacy or side effects.
Study details: Findings are from an analysis of 258 patients with RA from the TReasure Registry who were DMARD-IR and received first-line biologic therapy with tocilizumab as monotherapy (n = 80) or in combination with conventional synthetic DMARD (n = 178).
