Participants administered with ABBV-323 dose A IV at Week 0 and ABBV-323 dose B for 12 Weeks. Participants who achieve clinical response may enter the maintenance period in which participants are administered with ABBV-323 dose B
Drug: ABBV-323 Dose A
ABBV-323 Dose A is intravenously (IV) administered.
Other Name: Ravagalimab
Drug: ABBV-323 Dose B
ABBV-323 Dose B is administered subcutaneously (SC).
Other Name: Ravagalimab
- Percentage of Participants with Endoscopic Improvement [ Time Frame: At Week 8 ]Endoscopic Improvement is defined as Mayo endoscopic subscore of 0 or 1.
- Percentage of Participants with Clinical Remission per Adapted Mayo Score [ Time Frame: At Week 8 ]Clinical remission per Adapted Mayo score is defined as stool frequency subscore (SFS) <=1, and not greater than baseline, rectal bleeding subscore (RBS) = 0 , and endoscopic subscore <=1.
- Percentage of Participants with Clinical Response per Adapted Mayo Score [ Time Frame: At Week 8 ]Clinical response per Adapted Mayo score is defined as the decrease from Baseline >= 2 points and >= 30%, PLUS a decrease in RBS >=1 or an absolute RBS <=1.
- Percentage of Participants with Clinical Response per Partial Adapted Mayo Score [ Time Frame: Up to Week 12 ]Clinical response per Partial Adapted Mayo score is defined as decrease from baseline >=1 points and >=30%, PLUS a decrease in RBS >= 1 or an absolute RBS <=1.
- Percentage of Participants with Clinical Remission per Full Mayo Score in Participants with a Full Mayo Score of 6 to 12 at Baseline [ Time Frame: At Week 8 ]Clinical Remission per full Mayo score is defined as Full Mayo score <=2 with no subscore > 1.
- Percentage of Participants with Endoscopic Remission [ Time Frame: At Week 8 ]Endoscopic remission is defined as Mayo endoscopic subscore = 0.
