Change From Baseline in Crohn's Disease Activity Index (CDAI) Score

The CDAI score was generated using regression coefficients for eight different predictors of disease activity: severity of abdominal pain, general well-being, very soft/liquid stool frequency, extra-intestinal symptoms, need for antidiarrheal drugs, presence of an abdominal mass, body weight and hematocrit. Participants reported information regarding symptoms using a diary. The subscores of abdominal pain (0-3), general well-being (0-4), and number of very soft or liquid stools were then 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. Benchmarks for disease activity as measured by the CDAI were: \<150, clinical remission; 150 to 219, mildly active disease; 220-450, moderately active disease; and \>450, very severe disease.

Baseline to Week 12

Number of Participants Who Demonstrated a Clinical Response as Measured by CDAI

The CDAI score was generated using regression coefficients for eight different predictors of disease activity: severity of abdominal pain, general well-being, very soft/liquid stool frequency, extra-intestinal symptoms, need for antidiarrheal drugs, presence of an abdominal mass, body weight and hematocrit. Participants reported information regarding symptoms using a diary. The subscores of abdominal pain (0-3), general well-being (0-4), and number of very soft or liquid stools were then 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. Benchmarks for disease activity as measured by the CDAI were: \<150, clinical remission; 150 to 219, mildly active disease; 220-450, moderately active disease; and \>450, very severe disease. Clinical response was defined as a reduction from baseline of ≥100 points or CDAI \<150

Week 12

Number of Participants Who Demonstrated CDAI Clinical Remission

The CDAI score was generated using regression coefficients for eight different predictors of disease activity: severity of abdominal pain, general well-being, very soft/liquid stool frequency, extra-intestinal symptoms, need for antidiarrheal drugs, presence of an abdominal mass, body weight and hematocrit. Participants reported information regarding symptoms using a diary. The subscores of abdominal pain (0-3), general well-being (0-4), and number of very soft or liquid stools were then 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. Benchmarks for disease activity as measured by the CDAI were: \<150, clinical remission; 150 to 219, mildly active disease; 220-450, moderately active disease; and \>450, very severe disease. CDAI clinical remission was defined as a CDAI score less than 150 at Week 12.

Week 12

Change From Baseline in Simple Endoscopic Score for Crohn's Disease (SES-CD) at Week 12

The SES-CD incorporated 4 descriptors: the ulcer size, the proportion of surface covered by ulcer, the proportion of surface covered by other lesions, and the presence of stenosis. Each descriptor was scored in 5 segments (ileum, right colon, transverse colon, left colon, and rectum). The total score ranged from 0 to 56, with higher scores indicating a worse outcome.

Baseline to Week 12

Number of Participants With Endoscopic Response at Week 12

Endoscopic Response was defined as a reduction of SES-CD score or Endoscopic Remission (defined as SES-CD ≤ 2) at Week 12.

Week 12

Number of Participants With Stool Frequency and Abdominal Pain (SFAP) Clinical Remission

SFAP clinical remission was defined as an abdominal pain score ≤1 (on a scale of 0-3 with 0 representing 'no pain' and 3 representing 'severe pain'), stool frequency ≤2.8, and both not worse than baseline at Week 12.
