[Translation] A Phase III, multicenter, randomized, parallel-group, double-blind, placebo-controlled induction study to evaluate the efficacy and safety of intravenous vedolizumab (300 mg) in Chinese subjects with moderately to severely active Crohn's disease, followed by an open-label extension phase
主要目的 在中国的中重度活动性CD受试者中,评价维得利珠单抗 IV对第14周临床应答的影响。
次要目的
评价维得利珠单抗 IV对第14周临床缓解的影响。
评价维得利珠单抗 IV对第14周内镜下应答的影响。
评价维得利珠单抗 IV对第14周临床应答和内镜下应答的影响。
在整个研究期间评价维得利珠单抗 IV治疗的安全性。
其他目的
免疫原性目的
在整个研究期间评价维得利珠单抗 IV治疗的免疫原性。
PK目的
提供中重度活动性CD中国受试者的维得利珠单抗浓度数据。
如果数据允许,将使用群体PK分析推导药代动力学参数(血浆浓度-时间曲线下面积、观察到的最大血浆浓度、IV给药后的总清除率等)。
[Translation] Primary Objective To evaluate the effect of vedolizumab IV on clinical response at week 14 in Chinese subjects with moderately to severely active CD.
Secondary Objectives
To evaluate the effect of vedolizumab IV on clinical remission at week 14.
To evaluate the effect of vedolizumab IV on endoscopic response at week 14.
To evaluate the effect of vedolizumab IV on clinical and endoscopic response at week 14.
To evaluate the safety of vedolizumab IV treatment throughout the study period.
Other Objectives
Immunogenicity Objectives
To evaluate the immunogenicity of vedolizumab IV treatment throughout the study period.
PK Objectives
To provide vedolizumab concentration data in Chinese subjects with moderately to severely active CD.
If data permit, population PK analysis will be used to derive pharmacokinetic parameters (area under the plasma concentration-time curve, maximum observed plasma concentration, total clearance after IV administration, etc.).
