A Study of Guselkumab in Participants With Moderately to Severely Active Crohn's Disease

Number of participants with clinical response through Week 48 were reported. Clinical response was defined as a greater than or equal to (>=) 100-point reduction from baseline in CDAI score or CDAI score less than (<) 150. The multi-item CDAI score assessed severity of illness by collecting information on 8 different Crohn's disease-related variables (extraintestinal manifestations, abdominal mass, weight, hematocrit, use of antidiarrheal drug(s) and/or opiates, total number of liquid or very soft stools, abdominal pain/cramps, and general well-being). The last 3 variables were scored over 7 days by the participant on a diary card. The total CDAI score ranged from 0 (improvement in disease activity) to 600 (more disease activity) in general: higher score indicated higher disease activities and a decrease in total CDAI score over time indicated improvement in disease activity.

Number of participants with clinical remission through Week 48 were reported. Clinical remission was defined as a Crohn's Disease Activity Index (CDAI) score <150. The multi-item CDAI score assessed severity of illness by collecting information on 8 different Crohn's disease-related variables (extraintestinal manifestations, abdominal mass, weight, hematocrit, use of antidiarrheal drug(s) and/or opiates, total number of liquid or very soft stools, abdominal pain/cramps, and general well-being). The last 3 variables were scored over 7 days by the participant on a diary card.

Number of participants with PRO-2 remission through Week 48 were reported. PRO-2 remission was defined as abdominal pain (AP) mean daily score at or below 1 and stool frequency (SF) mean daily score at or below 3, and no worsening of AP or SF from baseline. Mean daily AP score was defined as the sum of abdominal pain/cramps ratings in the previous 7 days in a diary card divided by the total number of days assessments were performed. Average daily SF score was defined as the sum of number of liquid or very soft stools in the previous 7 days in a diary card divided by the total number of days assessments were performed.

Each endoscopic component was scored from 0 (best) to 3 (worst) for each segment, resulting in a total score of up to 15 for each component, except for the narrowing component which only attain a maximum total score of 11 because, the presence of a narrowing that cannot be passed can be only observed once. The total SES-CD score was the sum of all the component scores across all the segments and it ranged from 0 (best) to 56 (worst), where higher scores indicated more severe disease.
