Endoscopic remission is defined as an endoscopy score of less than or equal to 1. Endoscopy score (mucosal appearance) ranges from 0-3 (0 = normal [intact vascular pattern; no friability or granulation], 1 = mild [erythema; decreased vascular pattern; minimal granularity], 2 = moderate [marked erythema; granularity; friability; absent vascular pattern; bleeding with minimal trauma; no ulcerations], 3 = severe [ulceration; spontaneous bleeding].

Per Protocol Population (PP) defined as all subjects who either completed the study or withdrew for reasons related to efficacy or AEs and who were deemed to be protocol-compliant.

Relapse is defined as withdrawal from the study due to lack of efficacy.

PP

Endoscopic remission with no or mild symptoms is defined as an endoscopy score of less than or equal to 1 and a combined symptom score (stool frequency plus rectal bleeding) of less than or equal to 1. Endoscopy score (mucosal appearance) ranges from 0-3 (0 = normal, 1 = mild , 2 = moderate, 3 = severe). Rectal bleeding is assessed on a scale from 0-3 (0 = no rectal bleeding, 1 = streaks of blood, 2 = obvious blood, 3 = mostly blood). Stool frequency is assessed on a scale of 0-2 (0 = 0-1 more than normal per day, 1 = 2-3 more than normal per day, 2 = 4 or more than normal per day).

PP

The modified UCDAI score is the sum of the scores of 4 parameters (stool frequency, rectal bleeding, endoscopy score, and physician global assessment), each scoring between 0 and 3, making 12 the worst score.

PP

Quality of life (QoL) was assessed using the SIBDQ. SIBDQ total score is calculated from the sum of 10 questions. Each question is scored on a scale from 1 (poor QoL) to 7 (good QoL) with total scores ranging from 10 to 70. Higher scores indicate better QoL.

Intent to treat (ITT) population defined as all randomized subjects who received at least 1 dose of investigational product. Analysis includes patients who completed an SIBDQ questionnaire at 6 months.
