Newest clinical trial results with antitumor necrosis factor and nonantitumor necrosis factor biologics for rheumatoid arthritis.

Overview

PURPOSE OF REVIEW: To highlight recent evidence from the clinical trials of anti-tumor necrosis factor (TNF) and non anti-TNF biologics for rheumatoid arthritis (RA) focused on comparative clinical efficacy including safety outcomes and medication discontinuation. RECENT FINDINGS: Patients with RA are sometimes able to attain low disease activity or remission since the introduction of biologic therapy for RA. Biologics like anti-TNF, anti-interleukin-6 (IL-6), anti-CD20 and those that modulate T-cell co-stimulation have consistently shown good efficacy in patients with RA. Preliminary data from comparative efficacy studies to evaluate the potential differences between anti-TNF and non anti-TNF biologics have shown little differences among these. There is ongoing work in comparative efficacy to answer this question further. SUMMARY: Biologic therapy in RA has significantly changed the course of RA in the last decade. Recently published clinical trials have been focused on comparative efficacy, cardiovascular safety of biologics and potential anti-TNF therapy discontinuation in patients with RA.
