Description
Inclusion Criteria:
- Confirmed diagnosis of ileocolonic or colonic CD with at least 3 months or longer prior to the baseline;
- Central read total SES-CD score of ≥7. For isolated ileal disease, SES-CD total score should be ≥4;
- An average daily liquid/very soft SF ≥4 or daily AP score ≥2.0;
- CDAI between 220 and 450 inclusive;
- Must have inadequate response to, loss of response to, or intolerance to at least one conventional therapy for CD
Exclusion Criteria:
- Diagnosis of indeterminate colitis, microscopic colitis, ischemic colitis, infectious colitis, radiation colitis, diverticular disease, UC, or clinical findings suggestive of UC;
- Presence of active (draining) fistulae or intra-abdominal or perineal abscesses;
- Strictures or stenosis with obstructive symptoms;
- Short bowel syndrome;
- History of bowel perforation requiring surgical intervention within the past 12 months prior to baseline;
- Previous bowel surgery resulting in an existing stoma. Participants who have a j-pouch are excluded, as a j-pouch can result in a stoma;
- History of bowel surgery within 6 months prior to baseline.

Measure Description |
Time Frame |
|---|---|---|
|
Proportion of participants with endoscopic response 50
Time Frame: Week 14
|
Endoscopy response 50 (SES-CD50) is defined as a reduction from baseline in Simple Endoscopic Score for Crohn's Disease (SES-CD) at least 50% or more.
SES-CD score assesses the presence of ulcers, the percentage of ulcerated surface, the percentage of affected surface, and the presence of narrowing using scales ranging from 0 to 3 in each following bowel segment: Ileum, right colon, transverse colon, left colon, rectum.
The score ranges from 0 to 60 with higher score indicating more severe disease.

Outcome Measure |
Measure Description |
Time Frame |
|---|---|---|
|
Proportion of participants with a Crohn's Disease Activity Index (CDAI) clinical remission
Time Frame: Week 14
|
Clinical remission is defined as CDAI < 150.
CDAI is a composite index consisting of weighted scoring of 8 disease variables: number of liquid stools, extent of abdominal pain, general well-being, occurrence of extraintestinal symptoms, need for antidiarrheal drugs, presence of abdominal masses, hematocrit, and body weight.
CDAI scores range from 0 to approximately 600 points, higher score indicates higher disease activity.
|
Week 14
|
|
Proportion of participants achieving endoscopic remission
Time Frame: Week 14
|
Endoscopic remission is defined as SES-CD < 4 and at least 2-point reduction versus Baseline and no individual subscore > 1
|
Week 14
|
|
Proportion of participants achieving endoscopic mucosal healing
Time Frame: Week 14
|
Endoscopic mucosal healing defined as complete absence of ulcers in SES-CD
|
Week 14
|
|
The proportion of participants with Inflammatory Bowel Disease Questioners (IBDQ) total score ≥170
Time Frame: Week 14
|
Inflammatory Bowel Disease Questionnaire (IBDQ) score ranges from 32 to 224.
A higher score indicates better quality of life.
A score of at least 170 corresponds to clinical remission.
|
Week 14
|
|
Proportion of participants achieving endoscopic response
Time Frame: Week 52
|
Endoscopic response defined as improvement of SES-CD score at least 50% from baseline
|
Week 52
|
|
Proportion of participants with a CDAI clinical remission
Time Frame: Week 52
|
Clinical remission is defined as CDAI < 150.
CDAI is a composite index consisting of weighted scoring of 8 disease variables: number of liquid stools, extent of abdominal pain, general well-being, occurrence of extraintestinal symptoms, need for antidiarrheal drugs, presence of abdominal masses, hematocrit, and body weight.
CDAI scores range from 0 to approximately 600 points, higher score indicates higher disease activity.

Time Frame: Week 52
|
Endoscopic remission is defined as SES-CD < 4 and at least 2-point reduction versus Baseline and no individual subscore > 1
|
Week 52
|
|
Proportion of participants achieving endoscopic mucosal healing
Time Frame: Week 52

|
Proportion of participants with a CDAI clinical response
Time Frame: Up to week 52
|
As defined by a decrease from baseline in CDAI score of at least 100 points or more
|
Up to week 52
|
|
Proportion of participants achieving Patient Reported Outcome 2 (PRO2) clinical response
Time Frame: Up to week 52
|

|
Up to week 52
|
|
Proportion of participants achieving PRO2 clinical remission
Time Frame: Up to week 52
|
PRO2 clinical remission is defined as SF≤2.5 and AP≤1
|
Up to week 52
|
