Abstract

Some studies have shown that switching patients from one tumor necrosis factor (TNF)-alfa inhibitor to another may be beneficial when they have an inadequate response or an adverse event.We sought to assess the variables predicting the efficacy of the second TNF-alfa inhibitor in patients discontinuing the first TNF-alfa inhibitor.Data from all 5423 consecutive patients starting TNF-alfa inhibitor therapy for psoriasis between September 2005 and September 2010 who were included in the Italian Psocare registry were analyzed.In 105 patients who switched to a second TNF-alfa inhibitor who had complete follow-up data, 75\% improvement in the Psoriasis Area Severity Index score (PASI 75) was reached by 29\% after 16 weeks and by 45.6\% after 24 weeks. Patients who switched because of secondary loss of efficacy (loss of initial PASI 75 response) or adverse events/intolerance were more likely to reach PASI 75 than those who switched as a result of primary inefficacy (PASI 75 never achieved) (hazard ratio 2.7, 95\% confidence interval 1.3-5.5 vs hazard ratio 2.0, 95\% confidence interval 1.0-3.9 and 1, respectively).There was a small number of patients with complete follow-up data.PASI 75 response in patients who switched from one anti-TNF-alfa agent to another was significantly reduced in patients who showed primary inefficacy of the first anti-TNF-alfa.
