Study Groups

Brazikumab Induction Dose
Administer at Week 0, Week 4, and Week 8
Brazikumab Induction Dose
Participants who met criteria for early termination due to lack of efficacy (rescue treatment criteria) or who did not meet CDAI response at Week 52 in the lead-in study D5121C00001 are considered inadequate/non responders, and will receive IV induction dosing brazikumab at Week 0, Week 4, and Week 8 followed by maintenance dosing of brazikumab subcutaneously every 4 weeks thereafter up to Week 52.
Brazikumab Maintenance Dose
Administer at 4-week intervals through Week 52 Participants who receive IV induction dosing will be administered brazikumab SC at 4-week intervals starting Week 12 through Week 52
Brazikumab Maintenance Dose
Responders from Lead-In study D5271C00001 who completed requirements through Week 52 and met CDAI response (CDAI score of \< 150 points or CDAI reduction from Baseline of ≥ 100 points) without ongoing rescue treatment at Week 52 in the lead-in study. will receive maintenance dose of brazikumab administered subcutaneously every 4 weeks through Week 52, starting at Week 0. The subcutaneous dose of brazikumab will be administered to all responders/completers in the lead-in study regardless of the prior treatment administered

2. A participant in Study D5271C00001 (Legacy #3150-301-008) who discontinued from the study due to lack of efficacy after a minimum of 12 weeks of double-blind treatment and met criteria for the use of rescue treatment in the lead-in protocol.
2. Criterion deleted as part of Amendment.
3. Each participant must have had the ileocolonoscopic procedure at the final visit (Week 52, Week 12, or early termination after Week 12 of Study D5271C00001 (Legacy # 3150-301-008).
