OBJECTIVE: Biologics for rheumatoid arthritis (RA) patients with moderate to severe disease may preserve joint function. Matrix metalloproteinase 3 (MMP-3), a key tissue degrading protease, is highly elevated in RA. MMP-3, which measures the total pool of circulating MMP-3 species (cMMP3), is a commonly measured biomarker in rheumatology. The aim was to investigate the association of activated MMP-3 (actMMP3) species with treatment response compared to cMMP-3. METHODS: The LITHE biomarker study (n=741) was a 1-year phase III, double-blind, placebo-controlled, parallel group study of TCZ in RA patients on stable methotrexate...
