Outcome Measures
Primary Outcomes (1)
Change in mean Crohn's disease Activity Index (CDAI) score from baseline to week 12
Change in Mean CDAI (Crohn's disease Activity Index). CDAI is a weighted index comprising eight Crohn's Disease (CD)-related clinical and laboratory variables, to assess CD disease activity. Three of the variables, stool frequency, abdominal pain, and general well-being, are patient-reported measures recorded daily. The total CDAI score is calculated using the sum of each variable times the multiplier. The total score range of the CDAI is from 0 to 600.
During screening to week 12
Secondary Outcomes (6)
The proportion of participants achieving endoscopic response at Week 12
During screening to week 12
Change from baseline in mean simple endoscopic score in Crohn's disease SES-CD at Week 12
