Outcomes
Primary Outcomes
Percentage of Participants With Crohn's Disease Activity Index (CDAI) Score < 150
Time Frame: Week 12
The CDAI is a composite score that is used to measure the clinical activity of Crohn's disease (CD). The CDAI uses a questionnaire with 8 disease activity variables: number of soft/liquid stools, severity of abdominal pain, general well-being, presence of complications, need for antidiarrheal drugs, presence of an abdominal mass, hematocrit, and deviation in body weight. The sub scores of number of soft/liquid stool, severity of abdominal pain (0 \[none\] to 3 \[Severe\]), general well-being (0 \[well\] to 4 \[terrible\] were summed over the 7 days prior to each visit. Additionally, the remaining predictors were also noted and weighted to create the total CDAI score which ranged from 0-600 with a higher score indicating a worse outcome.
Secondary Outcomes
- Percentage of Participants With Abdominal Pain and Stool Frequency Clinical Remission(Week 12)
- Percentage of Participants With a Simple Endoscopic Score for Crohn's Disease (SES-CD) Score Decrease From Baseline of ≥ 50%(Week 12)
- Percentage of Participants With Reduction From Baseline in the Crohn's Disease Activity Index (CDAI) Score of >= 100 Points or a Total CDAI Score < 150(Week 12)
- Percentage of Participants With a Crohn's Disease Endoscopic Index of Severity (CDEIS) Decrease From Baseline of ≥ 50%(Week 12)
- Percentage of Participants With Abdominal Pain (AP) and Stool Frequency (SF) Clinical Remission and an Endoscopic (50%) Response(Week 12)
- Percentage of Participants With Robarts Histologic Index (RHI) Mucosal Healing at Week 12(Week 12)
- Percentage of Participants With Crohn's Disease Activity Index (CDAI) Score Reduction From Baseline of ≥ 100 Points or CDAI Score < 150 and SES-CD Decrease From Baseline of ≥ 50%(Week 12)
- Percentage of Participants With Crohn's Disease Activity Index (CDAI) Score < 150 and Simple Endoscopic Score for Crohn's Disease (SES-CD) Score Decrease From Baseline of ≥ 50%(Week 12)
- Percentage of Participants With Abdominal Pain and Stool Frequency Clinical Remission and a Simple Endoscopic Score for Crohn's Disease (SES-CD) Score <= 4 Points and Decrease >= 2 Points(Week 12)
- Percentage of Participants With Global Histologic Activity Score (GHAS) Remission(Week 12)
- Percentage of Participants With CDAI Reduction From Baseline of >=70 Points(Week 12)
- Percentage of Participants With Absence of Ulcers ≥ 0.5 cm With no Segment With Any Ulcerated Surface ≥10%(Week 12)
