Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Percentage of Participants Achieving Clinical Remission at Week 40 of Study APD334-308	Clinical remission was based on the modified Mayo score (MMS). The MMS is a composite score of 3 assessments consisting of participant-reported symptoms using daily electronic (e)-diary and centrally read endoscopy: stool frequency (SF), rectal bleeding (RB) and endoscopic score (ES). Clinical remission was defined as SF sub-score = 0 (or = 1 with a greater than or equal to [>=] 1-point decrease from Baseline), RB sub-score = 0, and ES less than or equal to (<=) 1 (excluding friability). Each component sub-score ranged from 0 to 3 and total score range of the MMS was from 0 to 9, with higher scores indicating more severe disease.	Week 40 of APD334-308
Secondary	Percentage of Participants Achieving Endoscopic Improvement at Week 40 of Study APD334-308	Endoscopic improvement was defined as an ES <=1 (excluding friability) at Week 40 of APD334-308 compared with Week 12 of APD334-302. The ES ranged from 0 to 3 (where 0 = normal/inactive disease and 3 = severe disease); higher score indicated more severe disease.	Week 40 of APD334-308
Secondary	Percentage of Participants Achieving Symptomatic Remission at Week 40 of Study APD334-308	Symptomatic remission was defined as an SF sub-score = 0 (or = 1 with a >= 1 point decrease from Baseline) and RB sub-score = 0. The SF sub-score ranged from 0 to 3 (where 0 = normal number of stools and 3 = at least 5 stools more than normal) and RB sub-score ranged from 0 to 3 (where 0 = no blood and 3 = blood alone passes). Higher scores indicated more severe disease.	Week 40 of APD334-308
Secondary	Percentage of Participants With Mucosal Healing at Week 40 of Study APD334-308	Mucosal healing was defined as an ES <= 1 (excluding friability) with histologic remission measured by a Geboes Index score less than [<] 2.0). The ES ranged from 0 to 3 (where 0 = normal/inactive disease and 3 = severe disease). The Geboes score grading system, was a validated score for evaluating histologic disease activity in UC as follows: grade 0 = structural and architectural changes; grade 1 = chronic inflammatory infiltrate; grade 2 = lamina propria neutrophils and eosinophils; grade 3 = neutrophils in the epithelium; grade 4 = crypt destruction; grade 5 = erosions or ulceration. A higher Geboes score indicated more severe disease.	Week 40 of APD334-308
Secondary	Percentage of Participants, Who Had Not Been Receiving Corticosteroids for = 12 Weeks, Achieving Clinical Remission at Week 40 of Study APD334-308 Among Participants Receiving Corticosteroids at C5041015 (APD334-302) Study Entry	Clinical remission was based on the modified Mayo score (MMS). The MMS is a composite score of 3 assessments consisting of participant-reported symptoms using daily electronic (e)-diary and centrally read endoscopy: stool frequency (SF), rectal bleeding (RB) and endoscopic score (ES). Clinical remission was defined as SF sub-score = 0 (or = 1 with a greater than or equal to [>=] 1-point decrease from Baseline), RB sub-score = 0, and ES less than or equal to (<=) 1 (excluding friability). Each component sub-score ranged from 0 to 3 and total score range of the MMS was from 0 to 9, with higher scores indicating more severe disease.	Week 40 of APD334-308
Secondary	Percentage of Participants Achieving Sustained Clinical Remission	Clinical remission was based on the modified Mayo score (MMS). The MMS is a composite score of 3 assessments consisting of participant-reported symptoms using daily electronic (e)-diary and centrally read endoscopy: stool frequency (SF), rectal bleeding (RB) and endoscopic score (ES). Clinical remission was defined as SF sub-score = 0 (or = 1 with a greater than or equal to [>=] 1-point decrease from Baseline), RB sub-score = 0, and ES less than or equal to (<=) 1 (excluding friability). Each component sub-score ranged from 0 to 3 and total score range of the MMS was from 0 to 9, with higher scores indicating more severe disease. A subject with sustained clinical remission is defined as someone who achieved clinical remission at both Week 12 of APD334-302 and Week 40 of APD334-308.	Week 40 of APD334-308
