Change in Modified Mayo Score (MMS) at weeks 48 and 96 and in partial Modified Mayo Score (pMMS) MMS is a composite score of UC disease activity calculated as the sum of the following 3 subscores: 1. Stool frequency, scored from 0 (normal number of stools) to 3 (5 or more stools more than normal). 2. Rectal bleeding, scored from 0 (no blood seen) to 3 (blood alone passed). 3. Endoscopic evaluation, scored from 0 (normal or inactive disease) to 3 (severe disease, spontaneous bleeding, ulceration). The overall MMS ranges from 0 to 9 where higher scores represent more severe disease. pMMS is a composite score of UC disease activity calculed as the sum of the following 2 subscores: 1. Stool frequency, scored from 0 (normal number of stools) to 3 (5 or more stools more than normal). 2. Rectal bleeding, scored from 0 (no blood seen) to 3 (blood alone passed). The overall pMMS ranges from 0 to 6 where higher scores represent more severe disease.

Population: Number of patients in the Full analysis set is 217; number analyzed in different rows correspond to number of patients analysed in the relevant week (lower than the overall number analyzed in FAS)

Participants recorded stool frequency using a paper subject diary on a daily basis. The stool frequency subscore ranges from 0 to 3 according to the following scale: Score 0: Normal number of stools Score 1: 1 to 2 stools per day more than normal Score 2: 3 to 4 stools per day more than normal Score 3: 5 or more stools per day more than normal

Participants recorded rectal bleeding in a paper subject diary on a daily basis. Rectal bleeding score is taken as the worst subscore of the three most recent scores within 7 days prior to the visit. The rectal bleeding subscore ranges from 0 to 3 according to the following scale: Score 0: No blood seen Score 1: Streaks of blood with stool less than half the time Score 2: Obvious blood with stool most of the time Score 3: Blood alone passed A lower score represents an improvement in rectal bleeding.
