Scores generally range from 0 to 600, where remission of Crohn's disease is defined as CDAI \< 150, and very severe disease is defined as CDAI \> 450. The analysis over time was performed for the DB placebo-controlled period (Week 0 to Week 4), with comparisons between active treatment and placebo groups.

Percentage of Participants Who Achieved IBDQ Remission (IBDQ ≥ 170 Points) at Week 26 in Participants With Clinical Response (Decrease in CDAI ≥ 70 Points From Baseline) at Week 8

The IBDQ is a self-administered 32-item questionnaire to evaluate quality of life across 4 dimensional scores: bowel, systemic, social and emotional. Responses to each question range from 1 (severe problem) to 7 (normal health). Total IBDQ score is the sum of the responses to the individual IBDQ questions, and ranges from 32 to 224 with higher scores indicating a better quality of life. CDAI is used to assess the symptoms of participants with Crohn's Disease. Scores generally range from 0 to 600, where remission of Crohn's disease is defined as CDAI \< 150, and very severe disease is defined as CDAI \> 450.
