Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Part I: Change From Baseline in the Crohn's Disease Activity Index (CDAI) Score at Week 8 | Baseline to Week 8 | The CDAI is a validated multi-item measure of severity of illness derived as a weighted sum of 8 different Crohn's disease-related variables. The CDAI score was assessed by collecting information on 8 different Crohn's disease-related variables: extra-intestinal manifestations, abdominal mass, weight, hematocrit, total number of liquid stools, abdominal pain/cramping, use of antidiarrheal drug(s), and/or opiates, and general well-being. The last 4 variables were scored over 7 days by the participant on a diary card. In general, CDAI score ranges from 0 to approximately 600; higher score indicates higher disease activities. |
| Part II: Change From Baseline in the CDAI Score at Week 12 | Baseline to Week 12 | The CDAI is a validated multi-item measure of severity of illness derived as a weighted sum of 8 different Crohn's disease-related variables. The CDAI was assessed by collecting information on 8 different Crohn's disease-related variables: extra-intestinal manifestations, abdominal mass, weight, hematocrit, total number of liquid stools, abdominal pain/cramping, use of antidiarrheal drug(s) and/or opiates, and general well-being. The last 4 variables are scored over 7 days by the participant on a diary card. In general, CDAI score ranges from 0 to approximately 600; higher score indicates higher disease activities. |

PRO-2 scores ranges from 0 to approximately 300, higher score indicates higher disease activity. |
| Part II: Percentage of Participants in Clinical Remission at Week 12 as Measured by PRO-2 (PRO-2 <75) | Week 12 | Clinical Remission was defined as a PRO-2 score of \<75 point. |
| Part II: Percentage of Participants in Clinical Remission at Week 12 as Measured by CDAI (CDAI Less Than [<] 150) | Week 12 | Clinical Remission was defined as a CDAI score of \<150 point.

A decrease in CDAI over time indicates improvement in disease activity. In general, CDAI score ranges from 0 to approximately 600; higher score indicates higher disease activities. |
| Part II: Change From Baseline in Simple Endoscopic Score for Crohn's Disease (SES-CD) at Week 12 | Baseline, Week 12 | SES-CD is a validated instrument reflecting an endoscopist global appraisal of mucosal lesions in Crohn's disease. SES-CD grades lesions by location (5 bowel segments: ileum, right colon, transverse colon, left colon, and rectum) using 4 endoscopic variables: ulcer size, extent of ulcerated surface, extent of affected surface, and presence/type of narrowing. The total SES-CD was calculated as the sum of the 4 variables for the 5 bowel segments: rectum, left colon, transverse colon, right colon, and ileum. Scores range from 0 to 60, with higher scores indicating more severe disease. |
| Part II: Percentage of Participants in Clinical Response at Week 12 as Measured by PRO-2 (>=50-point Reduction From Baseline in PRO-2 Score or PRO-2 Score <75) | Week 12 | Clinical response was defined as \>=50-point reduction from baseline in PRO-2 or Score or PRO-2 Score \<75. |
| Part II: Percentage of Participants in Clinical Response at Week 12 as Measured by CDAI (Greater Than or Equal to [>=] 100-point Reduction From Baseline in CDAI or CDAI <150) | Week 12 | Clinical response was defined as a \>=100-point reduction from the baseline CDAI score, or a CDAI score \<150.

Outcome results
Part I: Change From Baseline in the Crohn's Disease Activity Index (CDAI) Score at Week 8
The CDAI is a validated multi-item measure of severity of illness derived as a weighted sum of 8 different Crohn's disease-related variables. The CDAI score was assessed by collecting information on 8 different Crohn's disease-related variables: extra-intestinal manifestations, abdominal mass, weight, hematocrit, total number of liquid stools, abdominal pain/cramping, use of antidiarrheal drug(s), and/or opiates, and general well-being. The last 4 variables were scored over 7 days by the participant on a diary card. In general, CDAI score ranges from 0 to approximately 600; higher score indicates higher disease activities.
Time frame: Baseline to Week 8
Population: The efficacy analyses were based on the Full analysis set (FAS) included all randomized participants in Part 1 who received at least 1 dose of study agent.

Part II: Percentage of Participants in Clinical Response at Week 12 as Measured by CDAI (Greater Than or Equal to [>=] 100-point Reduction From Baseline in CDAI or CDAI <150)
Clinical response was defined as a \>=100-point reduction from the baseline CDAI score, or a CDAI score \<150. The CDAI score is used to quantify the symptoms of participants with Crohn's Disease. The CDAI is a validated multi-item measure of severity of illness derived as a weighted sum of 8 different Crohn's disease-related variables. extra-intestinal manifestations, abdominal mass, weight, hematocrit, total number of liquid stools, abdominal pain/cramping, use of antidiarrheal drug(s) and/or opiates, and general well-being. The CDAI score is used to quantify the symptoms of participants with Crohn's Disease. A decrease in CDAI over time indicates improvement in disease activity. In general, CDAI score ranges from 0 to approximately 600; higher score indicates higher disease activities.
Time frame: Week 12
Population: FAS included all randomized participants in Part II who received at least 1 dose of study agent.
