Brief Summary
This study seeks to evaluate the safety and efficacy of brazikumab versus placebo (Stage I) and versus an active comparator (Stage 2) in participants with moderately to severely active CD and will include assessments of clinical response as demonstrated by improvement of symptoms and colonic mucosal appearance as observed on endoscopy

Outcome Measures
Primary Outcomes (3)
Stage 1. Percentage of patients with CDAI remission
CDAI remission is defined as achieving the CDAI score below 150 (measured by PRO questionnaire and objective items (i.e. weight, hematocrit)).
at Week 12
Stage 2. Percentage of patients with endoscopic response
Endoscopic response is described as minimum of 50% decrease from Baseline in SES-CD total score.
at Week 52
Stage 2. Percentage of patients with clinical remission
Clinical remission is defined for a participant to satisfy the following two response thresholds simultaneously: average daily LSF subscore of ≤ 3 as assessed on the CDAI LSF item AND average daily AP subscore of ≤ 1 as assessed on the CDAI AP item (measured by PRO questionnaire).
at Week 52

Eligibility Criteria
You may not qualify if:
- At the time of signing the informed consent, the participant must be 18 to 80 years of age, inclusive.
- 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
- 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.
- Participants taking 5-aminosalicylates, Oral prednisone (or equivalent), Budesonide, Immunomodulators, Oral antibiotics, Immunomodulators, Probiotics must be at a stable dose.
- Participant must have the QFT-TB test performed and meet the following TB criteria.
- A TB worksheet must also be completed:
- Participant has no known history of active TB.
- Participant has no known history of latent TB without completion of an appropriate course of intervention.
- 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:
- no symptoms/risk factors per TB worksheet provided by the sponsor
- no known recent exposure to a case of active TB
- no evidence of active TB on chest x-ray within 8 weeks prior to Screening or during Screening
- confirmed QFT-TB negative by central laboratory
- 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.
