What is being measured
The primary outcome is the main question the study is designed to answer.
Total Mayo Score at Week 8 (Induction Period)
The Mayo score is a tool designed to measure disease activity for ulcerative colitis. The Mayo scoring system ranges from 0 to 12 points and consists of 4 subscores, which are stool frequency, rectal bleeding, findings on endoscopy and physician's global assessment. Each subscore graded 0 to 3 with the higher score indicates more severe disease activity and lower score denotes improvement of disease activity as measured by the total Mayo score.
Measured: Week 8
Secondary outcomes (34)
Number of Participants With AEs, SAEs and Discontinuation Due to AEs (Chronic Period)
An AE was an untoward medical occurrence in a participant who received study treatment without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes: death, life-threatening experience, initial or prolonged inpatient hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect. Treatment-emergent AEs were those with initial onset or that worsen in severity after the first dose of study medication. All AEs mentioned below are treatment-emergent AEs.

Measured: Week 8 to Week 32
Number of Participants With Laboratory Test Abnormalities-clinical Chemistry (Chronic Period)
The number of participants with a laboratory abnormality meeting specified criteria while on study treatment or during lag time are reported here. Baseline is defined as the last measurement prior to receiving study treatment. The list of serum chemistry test parameters were as follows: blood urea nitrogen, creatinine, cystatin C, glucose, calcium, sodium, potassium, gamma glutamyl transferase, chloride, aspartate aminotransferase (AST), alanine aminotransferase (ALT), total bilirubin, direct bilirubin, alkaline phosphatase, uric acid, albumin, total protein, creatine kinase (CK), total cholesterol, triglycerides, high-density lipoproteins (HDL), and low-density lipoprotein (LDL).
Measured: Week 8 to Week 32
Number of Participants With Laboratory Test Abnormalities-urinalysis (Chronic Period)
The number of participants with a laboratory abnormality meeting specified criteria while on study treatment or during lag time are reported here. Baseline is defined as the last measurement prior to receiving study treatment. The list of urinalysis test parameters were as follows:pH, glucose (qual), protein (qual), blood (qual), ketones, nitrites, leukocyte esterase, microscopy, and spot urine albumin/creatinine ratio. The criteria of laboratory abnormality is defined as one of the following conditions was met: 1)associated with accompanying symptoms;2)Test result requires additional diagnostic testing or medical/surgical intervention;3)Test result leads to a change in study dosing (outside of any protocol specified dose adjustments) or discontinuation from the study, significant additional concomitant drug treatment, or other therapy;4)Test result is considered to be an AE by the investigator or sponsor.
Measured: Week 8 to Week 32
Number of Participants With Adverse Events (AEs), Serious Adverse Events (SAEs) and Discontinuation Due to AEs (All-causalities) (Induction Period)
An AE was an untoward medical occurrence in a participant who received study treatment without regard to possibility of causal relationship. An SAE was an AE resulting in any of the following outcomes: death, life-threatening experience, initial or prolonged inpatient hospitalization, persistent or significant disability/incapacity, congenital anomaly/birth defect.

Primary outcome
Total Mayo Score at Week 8 (Induction Period)
Time frame: Week 8
The Mayo score is a tool designed to measure disease activity for ulcerative colitis. The Mayo scoring system ranges from 0 to 12 points and consists of 4 subscores, which are stool frequency, rectal bleeding, findings on endoscopy and physician's global assessment. Each subscore graded 0 to 3 with the higher score indicates more severe disease activity and lower score denotes improvement of disease activity as measured by the total Mayo score.

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 21 Jul 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?
Total Mayo Score at Week 8 (Induction Period) (time frame: Week 8). 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 NCT02958865, which also lists 5 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?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Jul 2022.
