简要总结
The purpose of this study is to characterize the safety, efficacy and dose response of BMS-945429 in subjects with moderate to severe Crohn's disease and who have had an insufficient response to conventional therapy or have failed Anti-Tumor Necrosis Factor (anti-TNF) therapy.

结局指标
主要结局
Percent of Participants With Clinical Remission (CDAI<150) as Measured by the Crohn's Disease Activity Index (CDAI)
时间窗: At 8 weeks during the Induction Period
CDAI scores range from 0 to 600. A score of less than 150 corresponds to relative disease quiescence (remission); 150 to 219, mildly active disease; 220 to 450, moderately active disease; and greater than 450, severe disease. A decrease in greater than 100 points indicates a clinically significant improvement in disease activity
次要结局
- Observed Maximum Concentration (Cmax) of Clazakizumab During the Induction Period(Week 0 and Week 4)
- Change From Baseline at Week 8 and 12 of Inflammatory Bowel Disease Questionnaire (IBDQ) Score(Week 8 and Week 12)
- Number of Participants During the Induction Period With Anti-clazakizumab Antibodies(Up to Week 12)
- Percent of Participants With Clinical Response (>100 Point Decrease in CDAI) During Induction Period as Measured by CDAI(At 8 weeks during the Induction Period)
- Steady-state Trough Concentration (Cmin) of Clazakizumab During the Induction Period(Week 4, Week 8)
- Area Under the Plasma Concentration-time Curve in One Dosing Interval [AUC(TAU)] of Clazakizumab During the Induction Period(Week 0, Week 4, Week 8)
