点击翻译按钮获取中文摘要

The purpose of this study is to determine the safety and efficacy of anti-IL-12 antibody therapy in active Crohn's disease. During this year we screened 11 and enrolled 8 subjects in this protocol. All successfully completed the treatment phase, and are now in follow-up. Two subjects had exacerbations of their disease 12 weeks after the last dose of study drug, and were transferred to standard therapy. This study uses a placebo-controlled, double-blind design, but 80% of enrolled subjects get the active compound. Assuming a majority of subjects received the active compound, we have observed significant improvement in clinical symptoms of disease, improvement of the endoscopic appearance of disease, and evidence of colonic mucosal inflammatory effector cell apoptosis following administration of the study drug. The study is continuing to enroll subjects, and no interim data analysis is available. A recent Data Safety Monitoring Board review of this protocol gave recommendations to proceed with the study without modifications.
