* Participants must have active moderate to severe ileal (terminal ileum), ileocolic, or colonic CD at baseline (Visit 2) as defined by:

1. CDAI score between 220 and 450 (inclusive) AND
2. Meeting the following subscores in the 2 item PRO:

i. Abdominal pain subscore >= 5 (average worst daily pain on the 11 point NRS) and abdominal pain subscore >= 2 (average daily pain on the 4-point abdominal pain variable of CDAI) over the 7 most recent days out of the 10 days before colonoscopy preparation (may or may not be contiguous) AND/OR ii. Average of the daily stool frequency subscore >=4 of type 6/7 (very soft stools/liquid stools) as shown in the BSFS over the 7 most recent days out of the 10 days before colonoscopy preparation (may or may not be contiguous) c.

* Participants must have a documented diagnosis (endoscopic with histology) of CD for >=3 months before screening. Documented diagnosis is defined as:

1. A biopsy report in which the description of the histological findings is consistent with the CD diagnosis AND
2. A report documenting disease duration based upon prior colonoscopy Note: If a biopsy report is not available in the source document at the time of screening, a biopsy must be performed during the screening colonoscopy and the histology report should be consistent with the CD diagnosis. If the histology description does not support the CD diagnosis at this time point, the participant should not be randomized

* Participants with abnormal chest x-ray or other imaging findings at screening (Visit 1), such as presence of active tuberculosis (TB), general infections, heart failure, or malignancy (A chest x-ray, computed tomography scan, etc, performed up to 12 weeks before study entry [screening, Visit 1] may be used if available; documentation of the official reading must be located and available in the source documentation)
* Participants with evidence of active or latent infection with Mycobacterium tuberculosis (TB) or participants with this history who have not completed a generally accepted full course of treatment before baseline (Visit 2) are excluded all other participants must have either the Mantoux (purified protein derivative [PPD]) tuberculin skin test or interferon-gamma release assay (IGRA) performed

Participants who have no history of previously diagnosed active or latent TB are excluded if they have a positive Mantoux (PPD) tuberculin skin test (ie >= 5 millimeter [mm] induration) or a positive IGRA (the latter to be tested at the site's local laboratory) during screening or within 12 weeks before screening If the IGRA cannot be performed locally, a central laboratory may be used, with prior agreement from the sponsor:

1. An IGRA is strongly recommended for participants with a prior Bacillus Calmette-Guérin vaccination but may be used for any participant Documentation of IGRA product used and the test result must be in the participant's source documentation if performed locally Acceptable IGRA products include QuantiFERON-TB Gold Plus In-Tube Test
2. If the results of the IGRA are indeterminate, the test may be repeated, and if a negative result is obtained, enrollment may proceed In participants with no history of treated active or latent TB, a positive test on repeat will exclude the participantParticipants with a history of active or latent TB infection must follow instructions for "Participants with a prior diagnosis of active or latent TB are excluded unless both of the following criteria are met" in this criterion
3. Participants with repeat indeterminate IGRA results, with no prior TB history, may be enrolled after consultation with a pulmonary or infectious disease specialist who determines low risk of infection (ie, participant would be acceptable for immunosuppressant [eg, anti-TNF] treatment without additional action) This consultation must be included in source documentation Results from a chest x-ray, taken within the 12 weeks before or during screening (Visit 1)must show no abnormalities suggestive of active TB infection as determined by a qualified medical specialist

a. Any major illness/condition or evidence of an unstable clinical condition (eg, renal, hepatic, hematologic, GI [except disease under study], endocrine, cardiovascular, pulmonary, immunologic [eg, Felty's syndrome], or local active infection/infectious illness) that, in the investigator's judgment will substantially increase the risk to the subject if he or she participates in the study b. Cancer or history of cancer or lymphoproliferative disease within the previous 5 years (other than resected cutaneous basal cell carcinoma, squamous cell carcinoma, or carcinoma in situ of the uterine cervix that has been treated with no evidence of recurrence) c. Presence of acute coronary syndrome (eg, acute myocardial infarction, unstable angina pectoris) within 24 weeks before screening (Visit 1) d.

* Participant with primary sclerosing cholangitis
* Participant with evidence of positive hepatitis B surface antigen (HBsAg) or hepatitis B core antibody (HBcAb) Note: if a subject tests negative for HBsAg, but positive for HBcAb, the subject would be considered eligible if no presence of hepatitis B virus (HBV) DNA is confirmed by HBV DNA polymerase chain reaction (PCR) reflex testing performed in the central laboratory
* Participant with chronic hepatitis C virus (HCV) (positive HCV antibody [HCVAb] and HCV RNA) Note: Participant who are HCVAb positive without evidence of HCV RNA may be considered eligible (spontaneous viral clearance or previously treated and cured [defined as no evidence of HCV RNA at least 12 weeks prior to baseline])
* Participant with any of the following abnormalities in hematology and/or serum chemistry profiles during screening (Visit 1) Note: Screening laboratory tests, if the results are considered by the investigator to be transient and inconsistent with the subject's clinical condition, may be repeated once during the screening period for confirmation results must be reviewed for eligibility prior to the screening colonoscopy procedure

* Participant with known human immunodeficiency virus (HIV) infection based on documented history with positive serological test, or positive HIV serologic test at screening, tested at the site's local laboratory in accordance with country requirements or tested at the central laboratory Note: A documented negative HIV test within 6 months of screening is acceptable and does not need to be repeated
* With known human immunodeficiency virus (HIV) infection based on documented history with positive serological test, or positive HIV serologic test at screening, tested at the site's local laboratory in accordance with country requirements or tested at the central laboratory.
