Percentage of Participants with Clinical Remission at Week 8 (Co-primary Endpoint)
Clinical remission is defined as a crohn's disease activity index (CDAI) score of less than (\<) 150 (in general, CDAI score ranges from 0 to approximately 600; higher score indicates higher disease activities). CDAI will be assessed by collecting information on 8 different Crohn's disease-related variables: extra-intestinal manifestations, abdominal mass, weight, hematocrit, total number of liquid or very soft stools, abdominal pain \[AP\]/cramping, use of antidiarrheal drug(s) and/or opiates, and general well-being. The last 4 variables are scored over 7 days by the participant on a diary card that participants are to complete on a daily basis.
Time frame: Week 8
Percentage of Participants with Endoscopic Response at Week 16 (Co-primary Endpoint)
Endoscopic response is defined as at least 50 percent (%) improvement from baseline in Simple Endoscopic Score for Crohn's Disease (SES-CD) score or SES-CD score less than or equal to (\<=) 2. The SES-CD score is based on the evaluation of 4 endoscopic components (presence/size of ulcers, percentage of mucosal surface covered by ulcers, the percentage of affected surface, and presence/type of narrowing/strictures) across 5 ileocolonic segments. Each endoscopic component is scored from 0 to 3 for each segment, and a total score is derived from the sum of all the component scores (range, 0 \[remission\] to 56 \[the most severe endoscopic activity\]).
Time frame: Week 16
Percentage of Participants with Clinical Remission at Week 52 (Major Secondary Endpoint)
Percentage of participants with clinical remission at Week 52 will be reported.
Time frame: Week 52
Percentage of Participants with Patient-reported Outcome (PRO)-2 Remission at Week 8 (Major Secondary Endpoint: Co-endpoint)
PRO-2 remission is defined as an AP mean daily score at or below 1 (AP\<=1) and a stool frequency (SF) mean daily score at or below 3 (SF\<=3), and no worsening of AP or SF from baseline.

Change from Baseline in Each of 4 Impairments from Work Productivity and Activity Impairment Questionnaire in Crohn's Disease (WPAI-CD) at Week 8 and Week 52
The WPAI-CD is a validated instrument created as a patient-reported quantitative assessment of the amount of absenteeism, presenteeism, and daily activity impairment attributable to CD. The WPAI-CD consists of 6 questions to determine employment status, hours missed from work due to Crohn's disease, hours missed from work for other reasons, hours worked, the degree to which Crohn's disease affected work productivity while at work, and the degree to which Crohn's disease affected activities outside of work. Four scores are derived: percentage of absenteeism, percentage of presenteeism (reduced productivity while at work), an overall work impairment score that combines absenteeism and presenteeism, and percentage of impairment in activities performed outside of work. Each of the four scores ranges from 0 to 100, with higher scores indicate greater impairment.
