At Week 52
Percentage of Participants with Clinical Remission per Crohn's Disease Activity Index (CDAI) Score
At Week 12

Percentage of participants achieving a CDAI score of \<150. The index is a weighted sum of scores on eight components: number of liquid or soft stools (stool frequency), abdominal pain, general well-being, number of complications, use of anti-diarrheal medication, presence of an abdominal mass, hematocrit, and percentage deviation from standard body weight. CDAI generally ranges from 0 to roughly 600, with higher values indicating greater activity.

Percentage of Participants with Clinical Remission
At Week 12

Percentage of participants achieving Modified Mayo Score (mMS) \<=2 with stool frequency subscore (SFS) = 0 or 1 (up to 1-2 stools more than normal), rectal bleeding subscore (RBS) = 0 (no blood seen) and endoscopic subscore (ES) = 0 or 1 (normal appearance of mucosa or mild disease) at Week 12. mMS is a composite score of ulcerative colitis disease activity, given by the sum of three subscores: SFS, RBS and ES. Each subscore is measured on a scale from 0 to 3, with higher values associated with greater severity.
