Treatment response to a second or third TNF-inhibitor in RA: results from the South Swedish Arthritis Treatment Group Register

Abstract

Response rates of first-time anti-TNF switchers are somewhat below those of anti-TNF naïve RA patients, while the markedly inferior response rates of second-time switchers suggest other therapeutic options to be considered in this situation. Identified baseline predictors of response may be useful indicators to second-line anti-TNF therapy, but vary depending on the response criteria set studied.
