Percentage of Participants Who Achieve Crohn's Disease Activity Index (CDAI) Score < 150 at Week 52 as Observed
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.
Time frame: Week 52
Percentage of Participants With a Simple Endoscopic Score for Crohn's Disease (SES-CD) Score Decrease From Baseline ≥ 50% Based on Observed Cases and Robarts Observed Scores
The SES-CD assessed the degree of inflammation. The SES-CD assesses the following 4 components: size of ulcers, ulcerated surface, affected surface, and presence of narrowing. Each of these components was scored on a scale of 0 (none/unaffected) to 3 (worst). In the SES-CD, each of these 4 components are assessed in the five segments: ileum, right colon, transverse colon, left colon, and rectum. The SES-CD was the sum of the individual scores of each of the components across the five segments. The range of SES-CD scores was 0 - 12 for each segment, and 0 - 60 for the overall SES-CD score, with larger scores indicating greater degree of inflammation. Baseline was defined as the last assessment prior to the start time of the first drug administration if time of measurement is available else the last assessment prior to or on the date of the first drug administration.

Time frame: Week 52
Percentage of Participants With Average Daily Abdominal Pain Score ≤1point and Average Daily Stool Frequency ≤ 3 Points With Abdominal Pain and Stool Frequency no Worse Than Baseline at Week 52
Abdominal pain (AP) and stool frequency (SF) clinical remission was defined as average daily abdominal pain score ≤ 1 point, and average daily stool frequency ≤3 times with AP and SF no worse than baseline at Week 12. Participants entered responses in diaries daily. The 7 days entries prior to visit were considered for calculating average AP score and SF. The AP was graded on severity of 0 (none) to 3 (severe) scale and SF was defined number of liquid or soft stools per day.

Percentage of Participants With Simple Endoscopic Score for Crohn's Disease (SES-CD) ≤ 4 Points and SES-CD Decrease From Baseline ≥ 2points With no SES-CD Subscore > 1 Point at Week 52 Based on Observed Cases
The SES-CD score is a way to measure how severe a person's bowel disease is. It looks at five different parts of the bowel and checks for ulcer size, ulcerated surface, inflamed surface, and stenosis. Each is given a score from 0 to 3 based on how bad the disease is. These scores are then added together for a total score ranging from 0 to 60. Higher scores indicate more severe disease.

Percentage of Participants With a Crohn's Disease Endoscopic Index of Severity (CDEIS) Decrease From Baseline ≥ 50% at Week 52
CDEIS is an index for determining the severity of Crohn's disease with endoscopic localization to ileum and colon. The CDEIS divides the intestine into 5 segments: rectum, sigmoid and left colon, transverse colon, right colon, and ileum. Four variables are assessed in each segment: the presence of deep ulceration, the presence of superficial ulceration, the percentage of ulcerated surface, and the percentage of surface affected by CD, indicated on 10-cm visual analogue scales. In addition, the presence of ulcerated stenosis and the presence of nonulcerated stenosis are also assessed over the entire intestine. These factors are weighted and summed to calculate the total score ranging from 0- 44, with higher scores indicating more severe disease.
