BACKGROUND & AIMS: We performed a meta-analysis of placebo-controlled trials to evaluate safety and efficacy of tumor necrosis factor (TNF) antagonists for Crohn's disease.
METHODS: We searched MEDLINE, Cochrane Library, and EMBASE. The primary end points were clinical remission for luminal Crohn's disease and fistula closure at > or =2 consecutive visits. Deaths, serious infections, and malignancies were also analyzed by the methods of Peto and Der Simonian and Laird.
RESULTS: Fourteen luminal Crohn's disease trials enrolled 3995 patients. In overall analysis, anti-TNF therapy was effective for induction of remission at week 4 (mean difference, 11%; 95% confidence interval [CI], 6%-16%; P < .001) and maintenance of remission at weeks 20-30 in patients who responded to induction therapy and in patients randomized before induction (mean difference, 23%; 95% CI, 18%-28% and mean difference, 8%; 95% CI, 3%-12%, respectively; P < .001 for all comparisons). Ten studies evaluated anti-TNF for treatment of fistulizing Crohn's disease, involving 776 patients. In overall analysis, anti-TNF therapy was effective for fistula closure only in maintenance trials after open-label induction (mean difference, 16%; 95% CI, 8%-25%; P < .001). In 21 studies enrolling 5356 individuals, anti-TNF therapy did not increase the risk of death, malignancy, or serious infection.
CONCLUSIONS: Infliximab, adalimumab, and certolizumab are effective in luminal Crohn's disease. Efficacy of anti-TNF agents other than infliximab in treating fistulizing Crohn's disease requires additional investigations. A longer duration of follow-up and a larger number of patients are required to better assess the safety profile of TNF antagonists in Crohn's disease.
