Percentage of Participants Achieving Clinical Remission Based on the CDAI at Week 12 |
Clinical remission is defined as a CDAI score of <150 points. CDAI assesses CD based on clinical signs such as number of liquid or very soft stools, abdominal pain, general wellbeing, extra-intestinal manifestations of CD, antidiarrheal use, presence of abdominal mass, hematocrit, and body weight. CDAI consists of eight factors, each summed after adjustment with a weighting factor. Total score ranges from 0 to 600 points. Higher scores indicate more severity. |

Percentage of Participants Exhibiting an Endoscopic Response Based on Simple Endoscopic Score for CD (SES-CD) at Week 12 |
Endoscopic response as per SES-CD is defined as SES-CD reduction by =50% from Baseline as scored by a central reviewer. SES-CD evaluates 4 endoscopic variables (ulcer size, percentage of the surface area that is ulcerated, percentage of the surface area affected, and presence and type of narrowings in 5 colonic segments evaluated during ileocolonoscopy (ileum, right colon, transverse colon, left colon, and rectum). Each variable is coded from 0 to 3 based on severity, where 0 is none or not severe and 3 is the most severe case, with the sum of the scores for each variable ranging from 0 to 15, except for presence of narrowing. Presence of narrowing ranges from 0 to 11 since a severity of 3 represents a narrowing which a colonoscope cannot be passed and, thus, can only be observed once among the bowel segments. The overall SES-CD score ranges from 0 to 56 and is the sum of 4 variables across 5 bowel segments. Higher scores indicate more severe disease. |

Percentage of Participants Achieving 2-item Patient-reported Outcome Measure (PRO2) Based Clinical Remission at Week 12 |
Clinical remission based on PRO2 is defined as 7-day average of very soft or liquid stool frequency (SF) =2.8, 7-day average of abdominal pain (AP) score =1.0, and neither worse than baseline. The PRO2 is comprised of the stool frequency and abdominal pain components of the CDAI. |

Percentage of Participants Achieving Endoscopic Remission Based on SES-CD at Week 12 |
Endoscopic remission as per SES-CD is defined as SES-CD score of =4 with no mucosal ulceration in the colon or ileum as assessed by centrally read video ileocolonoscopy. SES-CD evaluates 4 endoscopic variables (ulcer size, percentage of surface area (SA) that is ulcerated, percentage of SA affected, and presence and type of narrowings in 5 colonic segments evaluated during ileocolonoscopy. Each variable is coded from 0 to 3 based on severity, where 0 is none or not severe and 3 is most severe case, with sum of scores for each variable ranging from 0 to 15, except for presence of narrowing. Presence of narrowing ranges from 0 to 11 since a severity of 3 represents a narrowing which a colonoscope cannot be passed and, thus, can only be observed once among the bowel segments. The overall SES-CD score ranges from 0 to 56 and is sum of 4 variables across 5 bowel segments. Higher scores indicate more severe disease. |

Percentage of Participants Exhibiting Corticosteroid-free Clinical Remission in Participants who Were Taking Corticosteroids at Baseline Based on the CDAI at Week 12 |
Percentage of participants using oral corticosteroids at Baseline who have discontinued corticosteroids and are in clinical remission per CDAI at Week 12 will be reported. Clinical remission is defined as a CDAI score of <150 points. CDAI assesses CD based on clinical signs such as number of liquid or very soft stools, abdominal pain, general wellbeing, extra-intestinal manifestations of CD, antidiarrheal use, presence of abdominal mass, hematocrit, and body weight. CDAI consist of eight factors, each summed after adjustment with a weighting factor. Total score ranges from 0 to 600 points. Higher scores indicate more severity. |

Percentage of Participants Exhibiting a Clinical Response Based on the CDAI at Week 12 |
Clinical response is defined as =100-point decrease from Baseline in CDAI score. CDAI assesses CD based on clinical signs such as number of liquid or very soft stools, abdominal pain, general wellbeing, extra-intestinal manifestations of CD, antidiarrheal use, presence of abdominal mass, hematocrit, and body weight. CDAI consist of eight factors, each summed after adjustment with a weighting factor. Total score ranges from 0 to 600 points. Higher scores indicate more severity. |
