What is being measured
The primary outcome is the main question the study is designed to answer.
Percentage of Participants Achieving Endoscopic Response at Week 12
Endoscopic response defined as ≥ 50% reduction from baseline in Simple Endoscopic Score for Crohn's Disease (SES-CD) at Week 12. The SES-CD evaluates 4 endoscopic variables: presence and size of ulcers, proportion of surface covered by ulcers, proportion of surface affected by disease, and presence and severity of stenosis. The total SES-CD calculated as sum of 4 variables for 5 bowel segments: (ileum;right,transverse,and left colon;and rectum): presence and size of ulcers (none = score 0; diameter 0.1-0.5 cm = score 1; 0.5-2 cm = score 2; >2 cm = score 3); extent of ulcerated surface (none = 0; <10% = 1;10-30% = 2;>30% = 3);extent of affected surface (none = 0; <50% = 1;50-75% = 2;>75% =3); and presence and type of narrowings (none=0; single, can be passed=1; multiple,can be passed=2; cannot be passed=3). Total SES-CD scores range from 0 to 56, with higher scores indicating more severe disease.
Measured: Week 12
Secondary outcomes (9)
Percentage of Participants Achieving Endoscopic Remission at Week 12
Endoscopic remission defined as SES-CD of <4 ileal-colonic or <2 for isolated ileal disease, and no subscore >1 at week 12. The SES-CD evaluates 4 endoscopic variables: presence and size of ulcers, proportion of surface covered by ulcers, proportion of surface affected by disease, and presence and severity of stenosis. The total SES-CD is calculated as the sum of the 4 variables for the 5 bowel segments: (ileum; right, transverse, and left colon; and rectum): presence and size of ulcers (none = score 0; diameter 0.1-0.5 cm = score 1; 0.5-2 cm = score 2; greater than (>) 2 cm = score 3); extent of ulcerated surface (none = 0; less than (<) 10% = 1; 10-30% = 2; >30% = 3); extent of affected surface (none = 0; <50% = 1; 50-75% = 2; >75% = 3); and presence and type of narrowings (none=0; single, can be passed=1; multiple, can be passed=2; cannot be passed=3). Total SES-CD scores range from 0 to 56, with higher scores indicating more severe disease.
Measured: Week 12
Percentage of Participants Achieving Patient Reported Outcome Remission at Week 12
PRO remission is defined as stool frequency (SF) ≤2.5 and abdominal pain (AP) ≤1 and no worse than baseline at week 12. SF captures the number of liquid or very soft stools. AP score is classified as 0=none, 1=mild, 2=moderate, 3=severe.
Measured: Week 12
Mean Change From Baseline on the Patient Global Rating - Severity (PGRS) Crohn's Disease Score at Week 12
The PGRS is a 1-item patient-rated questionnaire designed to assess the participant's rating of their disease symptom severity over the past 24 hours. Responses are graded on a 6-point scale in which a score of 1 indicates the subject has no symptoms (that is, "none") and a score of 6 indicates that the participant's symptom are "very severe." Least Squares Mean (LS Mean) was calculated using Mixed Model for Repeated Measures (MMRM) model with treatment, geographic region, geographic region, prior biologic CD therapy use (prior biologic experience versus prior biologic naive), baseline score, visit, and the interaction of treatment-by-visit and baseline-by-visit as fixed factors.
Measured: Baseline, Week 12
Mean of Patient Global Rating - Change (PGRC) Crohn's Disease Score at Week 12
The PGRC scale is a patient-rated instrument designed to assess the participant's rating of change in their symptom(s). Responses are graded on a 7-point Likert scale in which a score of 1 indicates that the participant's symptom is "very much better," a score of 4 indicates that the participant's symptom has experienced "no change," and a score of 7 indicates that the participant's symptom is "very much worse."
Measured: Baseline, Week 12
Mean Change From Baseline on the Inflammatory Bowel Disease Questionnaire (IBDQ) Score at Week 12
The IBDQ is a 32-item self-administered questionnaire. The IBDQ has 4 dimensions: bowel symptoms (10 items), systemic symptoms (5 items), emotional function (12 items), and social function (5 items). Responses are graded on a 7-point Likert scale in which 7 denotes "not a problem at all" and 1 denotes "a very severe problem." Scores range from 32 to 224; a higher score indicates a better quality of life. LS Mean was calculated using Mixed Model for Repeated Measures (MMRM) model with treatment, geographic region, geographic region, prior biologic CD therapy use (prior biologic experience versus prior biologic naive), baseline score, visit, and the interaction of treatment-by-visit and baseline-by-visit as fixed factors.
Measured: Baseline, Week 12
Mean Change From Baseline on the Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) Score at Week 12
The Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-F) Scale is a13-item, symptom-specific questionnaire that specifically assesses the participant's self-reported severity of fatigue and its impact upon daily activities and functioning. The FACIT-F uses a numeric rating scale of 0-4 associated with a range over "Not at all" to "Very much" for each item to assess fatigue and its impact in the past 7 days. Total scores range from 0 to 52, with higher scores indicating less fatigue. LS Mean was calculated using Mixed Model for Repeated Measures (MMRM) model with treatment, geographic region, geographic region, prior biologic CD therapy use (prior biologic experience versus prior biologic naive), baseline score, visit, and the interaction of treatment-by-visit and baseline-by-visit as fixed factors.
Measured: Baseline, Week 12
Mean Change From Baseline on the 36-Item Short Form Health Survey (SF-36) Physical Component Summary (PCS) and Mental Component Summary (MCS) Scores at Week 12
The SF-36 is a health-related survey that assesses participant's quality of life and consists of 36 questions covering 8 health domains:physical functioning, bodily pain, role limitations due to physical problems and emotional problems, general health, mental health, social functioning, vitality, 2 component scores (MCS and PCS). MCS consisted of social functioning, vitality, mental health, and role-emotional scales. PCS consisted of physical functioning, bodily pain, role-physical, and general health scales. Each domain is scored by summing individual items and transforming scores into a 0 to 100 scale with higher scores indicating better health status or functioning. LS Mean was calculated using Mixed Model for Repeated Measures (MMRM) model with treatment, geographic region, geographic region, prior biologic CD therapy use (prior biologic experience versus prior biologic naive), baseline score, visit, and the interaction of treatment-by-visit and baseline-by-visit as fixed factors.
Measured: Baseline, Week 12

Primary outcome
Percentage of Participants Achieving Endoscopic Response at Week 12
Time frame: Week 12
Endoscopic response defined as ≥ 50% reduction from baseline in Simple Endoscopic Score for Crohn's Disease (SES-CD) at Week 12. The SES-CD evaluates 4 endoscopic variables: presence and size of ulcers, proportion of surface covered by ulcers, proportion of surface affected by disease, and presence and severity of stenosis. The total SES-CD calculated as sum of 4 variables for 5 bowel segments: (ileum;right,transverse,and left colon;and rectum): presence and size of ulcers (none = score 0; diameter 0.1-0.5 cm = score 1; 0.5-2 cm = score 2; >2 cm = score 3); extent of ulcerated surface (none = 0; <10% = 1;10-30% = 2;>30% = 3);extent of affected surface (none = 0; <50% = 1;50-75% = 2;>75% =3); and presence and type of narrowings (none=0; single, can be passed=1; multiple,can be passed=2; cannot be passed=3). Total SES-CD scores range from 0 to 56, with higher scores indicating more severe disease.

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Yes. Results are posted in the registry (first posted 28 Feb 2022). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Percentage of Participants Achieving Endoscopic Response at Week 12 (time frame: Week 12). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT02891226, which also lists 4 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
