Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 75 years (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Endoscopic Improvement During Induction Period
Time Frame: At Week 8
Endoscopic Improvement is defined as Mayo endoscopic subscore of 0 or 1. Mayo endoscopic score is classified as 0=Normal or inactive disease; 1=Mild disease (erythema, decreased vascular pattern); 2=Moderate disease (marked erythema, absent vascular pattern, friability, erosions); 3=Severe disease (spontaneous bleeding, ulceration). Higher score indicates worsening of the disease. The number of responders is calculated based on the total number of participants and estimated response rate, rounding to a nearest whole integer.
At Week 8

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Clinical Remission Per Adapted Mayo Score During Induction Period
Time Frame: At Week 8
Clinical remission per Adapted Mayo score is defined as stool frequency subscore (SFS) <=1, and not greater than baseline, rectal bleeding subscore (RBS) = 0, and endoscopic subscore <=1. The Adapted Mayo Score is a composite score of UC disease activity based on the following 3 subscores: Stool frequency subscore (SFS), scored from 0 (normal number of stools) to 3 (5 or more stools more than normal), Rectal bleeding subscore (RBS), scored from 0 (no blood seen) to 3 (blood alone passed), Endoscopic subscore confirmed by central reader, scored from 0 (normal or inactive disease) to 3 (severe disease, spontaneous bleeding, ulceration). The overall Adapted Mayo score ranges from 0 to 9 where higher scores represent more severe disease. The number of responders is calculated based on the total number of participants and estimated response rate, rounding to a nearest whole integer.
At Week 8
Percentage of Participants With Clinical Response Per Adapted Mayo Score During Induction Period
Time Frame: At Week 8
Clinical response per Adapted Mayo score is defined as the decrease from Baseline >= 2 points and >= 30%, PLUS a decrease in RBS >=1 or an absolute RBS <=1. The Adapted Mayo Score is a composite score of UC disease activity based on the following 3 subscores: Stool frequency subscore (SFS), scored from 0 (normal number of stools) to 3 (5 or more stools more than normal), Rectal bleeding subscore (RBS), scored from 0 (no blood seen) to 3 (blood alone passed), Endoscopic subscore, scored from 0 (normal or inactive disease) to 3 (severe disease, spontaneous bleeding, ulceration). The overall Adapted Mayo score ranges from 0 to 9 with higher scores representing more severe disease. The number of responders is calculated based on the total number of participants and estimated response rate, rounding to a nearest whole integer.
At Week 8
Percentage of Participants With Clinical Response Per Partial Adapted Mayo Score
Time Frame: Up to Week 8
Clinical response per Partial Adapted Mayo score is defined as decrease from baseline >=1 points and >=30%, PLUS a decrease in RBS >= 1 or an absolute RBS <=1. The Partial Adapted Mayo Score is a composite score of UC disease activity based on the following 2 subscores: SFS, scored from 0 (normal number of stools) to 3 (5 or more stools more than normal); RBS, scored from 0 (no blood seen) to 3 (blood alone passed). The overall Partial Adapted Mayo score ranges from 0 to 6 with higher scores representing more severe disease. The number of responders is calculated based on the total number of participants and estimated response rate, rounding to a nearest whole integer.
Up to Week 8
Percentage of Participants With Clinical Remission Per Full Mayo Score During Induction Period in Participants With a Full Mayo Score of 6 to 12 at Baseline
Time Frame: At Week 8
Clinical Remission per full Mayo score is defined as Full Mayo score <=2 with no subscore > 1. The Mayo score is a tool designed to measure disease activity for ulcerative colitis. The FMS ranges from 0 (normal or inactive disease) to 12 (severe disease) and is calculated as the sum of 4 subscores (stool frequency, rectal bleeding, endoscopy [confirmed by a central reader], and physician's global assessment), each of which ranges from 0 (normal) to 3 (severe disease). Endoscopies were assessed by a central reader. Negative changes indicate improvement. The number of responders is calculated based on the total number of participants and estimated response rate, rounding to the nearest whole integer.
At Week 8
Percentage of Participants With Endoscopic Remission During Induction Period
Time Frame: At Week 8
Endoscopic remission is defined as Mayo endoscopic subscore = 0. Endoscopies were assessed by a blinded central reader and scored according to the following scale: 0 = Normal or inactive disease; 1 = Mild disease (erythema, decreased vascular pattern); 2 = Moderate disease (marked erythema, lack of vascular pattern, any friability, erosions); 3 = Severe disease (spontaneous bleeding, ulceration). Higher score indicates worsening of the disease. The number of responders is calculated based on the total number of participants and estimated response rate, rounding to the nearest whole integer.
