Abstract
BACKGROUND: Since the beginning of 2005, etanercept and efalizumab are officially registered and reimbursed for the treatment of recalcitrant psoriasis in The Netherlands. OBJECTIVE: The evaluation of the efficacy, safety and adverse events of etanercept and efalizumab treatment in daily practice. METHODS: A prospective cohort study was carried out for patients treated with etanercept or efalizumab between February 2005 and March 2006. RESULTS: Over the past 13 months 45 individuals were treated with etanercept and 17 subjects were treated with efalizumab. The cohort represented a high-need population. At week 12, 82% of the subjects treated with 2 x 50 mg etanercept/week and 71% of the subjects treated with 2 x 25 mg etanercept/week reached a PASI-50. Efficacy of etanercept treatment was comparable to the results of clinical trials. For efalizumab, efficacy in responding patients was also comparable to clinical trial data, but the percentage of dropouts was substantial. During biologic treatment, safety was preserved and mainly mild adverse events were reported. CONCLUSION: Etanercept and efalizumab are effective and safe treatments of psoriasis, even in a high-need population. Etanercept was able to sustain the clinical improvement throughout 24 weeks, whereas efalizumab was not in 47% of subjects.
