Brief Summary:
The purpose of this OLE Study D5272C00002 (Legacy #3151-202-008) is to permit participants who previously enrolled in the double-blind Study D5272C00001 (Legacy #3151-201-008) to receive brazikumab, allowing for long-term observation of safety and efficacy in these participants treated with brazikumab. There are no formal hypotheses to be tested. Safety and efficacy data obtained in this study will be included in regulatory product submissions as appropriate.

Arm Intervention/treatment
Experimental: 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
Drug: Brazikumab Maintenance Dose
Completers in the lead-in study D5272C00001 (Legacy #3151-201-008) will receive a maintenance dose of brazikumab administered subcutaneously every 4 weeks up to Week 52 (Group A). The SC dose of brazikumab will be administered to all responders/completers in the lead-in study regardless of the prior treatment administered.

Experimental: Brazikumab Induction Dose
Administer at Week 0, Week 4, and Week 8
Drug: Brazikumab Induction Dose
Participants in the lead-in study D5272C00001 (Legacy #3151-201-008) who have not responded to treatment and have met criteria for rescue treatment are considered inadequate/non-responders (Group B). In these eligible participants, IV induction dosing of brazikumab at Week 0, Week 4, and Week 8 will be administered, followed by brazikumab administered subcutaneously every 4 weeks thereafter (up to Week 52).
