SES-CD score can range from 0 to 56. Higher scores indicating more severe disease.

Time frame: At Week 12

Maintenance Study: Number of Participants with Clinical Remission at Week 40 (Co-Primary Endpoint)

Clinical remission is defined as CDAI score \< 150. CDAI scores range from 0 to approximately 600. Higher score indicates higher disease activity.

Time frame: At Week 40

Maintenance Study: Number of Participants with Endoscopic Response at Week 40 (Co-Primary Endpoint)

Endoscopic response is defined as \> 50% improvement from baseline in SES-CD score or a decrease of at least 2 points in participants with a baseline score of 4 and isolated ileal disease. SES-CD score can range from 0 to 56. Higher scores indicating more severe disease.

Induction Study 1: Number of Participants with Clinical Remission at Week 12

Clinical remission is defined as CDAI score \< 150. CDAI scores ranging from 0 to approximately 600. Higher score indicates higher disease activity.

Time frame: At Week 12

Induction Study 1: Number of Participants with Endoscopic Response at Week 12

Time frame: At Week 12

Induction Study 1: Number of Participants with Adverse Events (AEs) and Serious Adverse Events (SAEs)

An AE is any untoward medical occurrence in a clinical study participant administered a pharmaceutical (investigational or non-investigational) product that does not necessarily have a causal relationship with the intervention. An SAE is any untoward medical occurrence that at any dose: results in death, is life-threatening, requires inpatient hospitalization or prolongation of existing hospitalization, results in persistent or significant disability/incapacity, is a congenital anomaly/birth defect, is a suspected transmission of any infectious agent via a medicinal product and is medically important.

Time frame: Up to 4 weeks after last dose of study drug (i.e., up to Week 16)

Induction Study 2: Number of Participants with Patient Reported Outcomes (PRO)-2 Remission at Week 12

PRO-2 remission is defined as an abdominal pain (AP) mean daily score less than or equal to (\<=) 1 and stool frequency (SF) mean daily score \<= 2.8, and no worsening of AP or SF from baseline.

Time frame: At Week 12

Induction Study 2: Number of Participants with Clinical Response at Week 12

Clinical response is defined as a \>= 100-point reduction from baseline in CDAI score.

Time frame: At Week 12

Induction Study 2: Number of Participants Reporting Both Clinical Remission and Endoscopic Response at Week 12

Clinical remission is defined as CDAI score \< 150. Endoscopic response is defined as \> 50% improvement from baseline in SES-CD score or a decrease of at least 2 points in participants with a baseline score of 4 and isolated ileal disease. This is a composite endpoint defined to measure achievement of both clinical remission and endoscopic response at the participant level.

Time frame: At Week 12

Induction Study 2: Number of Participants with Clinical Response at Week 4
