Abstract: OBJECTIVES: Etanercept, an injectable tumor necrosis factor (TNF) receptor fusion protein, binds and inactivates human TNF and is used in active rheumatoid arthritis. Blocking TNF with monoclonal antibodies has also been beneficial in Crohn's disease. We attempted to determine the efficacy and safety of etanercept for induction of clinical, endoscopic, and histological improvement in patients with moderate to severe Crohn's disease despite standard treatment. METHODS: Ten patients with active Crohn's disease were treated with etanercept (25 mg s.c.) twice per week for 12 wk. Background therapy was kept stable during the trial. Crohn's disease activity index (CDAI), Inflammatory Bowel Disease Questionnaire, and C-reactive protein levels were measured at weeks 0, 2, 4, 8, and 12. Colonoscopies were performed before and after therapy in responders; endoscopic biopsies were scored for inflammation. RESULTS: At week 2 after the start, a clinical response (deltaCDAI > or = 70) was observed in 6/10 patients (median = 305 [294-418] to 166 [107-392]), with reduction in serum C-reactive protein levels (median = 17.2 [6.8-67.2] to 9.1 [0.9-17.2] mg/dl). Colonoscopies showed a reduction in inflammatory lesions in the four patients who attained remission (CDAI < 150), whereas the inflammatory score of the biopsies did not decrease significantly. No moderate or severe adverse events were observed. CONCLUSIONS: Etanercept may be effective in Crohn's disease refractory to standard therapy.
