结局指标
主要结局
Percentage of Participants with Endoscopic Response at Week 48
时间窗: Week 48
Percentage of participants with endoscopic response at Week 48 will be reported. Endoscopic response is based on change from baseline in the simple endoscopic score for Crohn's disease (SES-CD), as assessed by central endoscopy reading.
Percentage of Participants with Clinical Remission at Week 48
时间窗: Week 48
Percentage of participants with clinical remission at Week 48 will be reported. Clinical remission is based on the Crohn's Disease Activity Index (CDAI).
