Key exclusion criteria
Exclusion Criteria are the same for both Stage 1 and Stage 2; however, participants enrolled in Stage 1 will not be permitted to enroll in Stage 2.

Inclusion Criteria:

1. At the time of signing the informed consent, the participant must be 18 to 80 years of age, inclusive.
2. A diagnosis of ileal, ileocolonic, or colonic CD with an onset of symptoms for a minimum of 3 months prior to Screening as determined by the investigator based on clinical history, exclusion of other etiologies including infectious causes, and characteristic endoscopic and/or histologic findings.
3. Moderately to severely active CD defined by a CDAI score of 220 to 450 AND; CDAI LSF score = 5 OR CDAI AP score = 2; AND SES-CD of at least 6
4. Participant had an inadequate response or intolerance to intervention with conventional treatment [oral aminosalicylates, oral CS, azathioprine, methotrexate, or 6-mercaptopurine], or prior biological treatment, or demonstrated CS dependence for the treatment of CD. For participants who have previously used biological treatment, a participant may have failed up to 3 biologics that include up to 2 different mechanisms of action.
5. Participants taking 5-aminosalicylates, Oral prednisone (or equivalent), Budesonide, Immunomodulators, Oral antibiotics, Immunomodulators, Probiotics must be at a stable dose.
6. Participant must have the QFT-TB test performed and meet the following TB criteria.

A TB worksheet must also be completed:

1. Participant has no known history of active TB.
2. Participant has no known history of latent TB without completion of an appropriate course of intervention.
3. Meets 1 of the following acceptable TB test results:

i. Negative QFT-TB obtained from central laboratory during Screening, OR ii. For a positive QFT-TB test obtained during Screening from the central laboratory, active TB must be ruled out or treated and negative QFT-TB confirmed by central laboratory OR iii. Indeterminate QFT-TB test obtained during the Screening Period from the central laboratory with ongoing QFT-TB testing as outlined in Appendix G. Participants with an indeterminate QFT-TB test can continue with Screening if they have all of the following:

1. no symptoms/risk factors per TB worksheet provided by the sponsor
2. no known recent exposure to a case of active TB
3. no evidence of active TB on chest x-ray within 8 weeks prior to Screening or during Screening
4. confirmed QFT-TB negative by central laboratory

7 Female participants of childbearing potential must have a negative urine pregnancy test prior to administration of study intervention and must agree to use a highly effective method of birth control (confirmed by the investigator) from randomization throughout the study duration and for at least 18 weeks after last dose of study intervention.

8 Women not of childbearing potential are defined as women who are either permanently sterilized or who are postmenopausal. Women will be considered postmenopausal if they have been amenorrhoeic for 12 months prior to the planned date of randomization without an alternative medical cause.

9 Nonsterilized males who are sexually active with a female partner of childbearing potential must comply with the methods of contraception during treatment and until the end of relevant systemic exposure in the male participant, plus a further 18 weeks.

10 Capable of giving signed informed consent, which includes compliance with the requirements and restrictions listed in the ICF and in the protocol.

11 Willingness and ability to attend all study visits, comply with the study procedures, read and write in order to complete questionnaires, and be able to complete the study period.

12 Provision of signed and dated written Optional Genetic Research Information informed consent prior to collection of samples for optional genetic research that supports Genomic Initiative.

Complete inclusion criteria are in the study protocol
