研究概览
简要总结
The purpose of this study is to evaluate the efficacy, safety, tolerability, and pharmacokinetics (PK) of teduglutide compared with placebo in subjects with parenteral nutrition (PN)-dependent short bowel syndrome (SBS).
详细描述
Teduglutide is an analog of glucagon-like peptide 2 (GLP-2), a naturally occurring hormone that regulates the growth, proliferation, and maintenance of cells lining the gastrointestinal tract. Teduglutide has been shown in animal studies and previous human clinical trials to increase the size and number of these cells, thereby increasing the absorptive surface area of the intestines.
The multicenter, double-blind, international Phase III trial will randomly assign approximately 80 patients to receive daily subcutaneous injections of 0.05 milligrams or 0.10 milligrams of teduglutide per kilogram of body weight, or a placebo. Dosing will continue for a period of six months. The primary endpoint in the study is a reduction in the use of intravenous feeding, which is often required to sustain life in patients with SBS.

结局指标
主要结局
A Graded Response Score in Parenteral Nutrition (PN) Reduction
时间窗: 6 months
The intensity of the response relied on a reduction from Baseline in weekly parenteral nutrition (PN) volume (minimum reduction of 20% and a maximum of 100%). Duration of the response incorporated responses at Weeks(Wk) 16-20 and at Wk20-24. Zero (0 - lowest) assigned if \<20% reduction at Wk20-24 and reduction at Wk16-20 of \< 20%, 20-39%, or \>=40%. One (1) assigned if reduction of 20-39% at Wk20-24 but \< 20% at Wk16-20. Two(2) assigned if reductions of 40-99% at Wk20-24 AND \<20% at Wk16-20 OR 20-39% at Wk20-24 AND 20-39% at Wk16-20. Three (3) assigned if reductions of 100% at Wk20-24 AND \<20% at Wk16-20 OR 40-99% at Wk20-24 AND 20-39% at Wk16-20 OR 20-39% at Wk20-24 AND \>=40% at Wk16-20. Four (4) assigned if reductions of 100% at Wk20-24 AND 20-39% at Wk16-20 OR 40-99% at Wk20-24 AND \>=40% at Wk16-20.
