Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. 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

  • Confirmed diagnosis of moderate to severe (Part A) or mild to moderate (Part B) UC for ≥3 months prior to baseline.
  • Active disease beyond the rectum (>15 cm of active disease from the anal verge at the screening endoscopy).

Part A (moderate to severe): Must have a 5 to 9 score on the modified mayo score, including an endoscopy subscore of at least 2. Part B (mild to moderate): Participants with mMS of 4 to 6, ES of ≥2 and RB score of ≥1

  • Must have inadequate response to, loss of response to, or intolerance to at least one conventional therapy for UC.
  • Total body weight >40 kg (88.2 lb).

Exclusion Criteria:

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
Part A: Proportion of participants achieving clinical remission at Week 12 in participants with moderate to severe UC.
Time Frame: Week 12
Clinical remission based on modified Mayo Score is defined as endoscopic subscore equal 0 or 1 (without friability), stool frequency subscore equal 0 or 1, and rectal bleeding subscore equal 0
Week 12
Part B: Percent change from baseline in the mMS in participants with mild to moderate UC.
Time Frame: Week 12
Week 12

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
Part A: Proportion of participants achieving improvement in endoscopic appearance at Week 12
Time Frame: Week 12
Endoscopic improvement is defined as a Mayo endoscopic subscore of ≤1 (without friability)
Week 12
Part A: Proportion of participants with clinical remission at Week 12
Time Frame: Week 12
Clinical Remission defined by Total Mayo Score ≤2 and no individual subscore >1 and rectal bleeding subscore of 0
Week 12
Part B: Proportion of participants achieving clinical remission at Week 12
Time Frame: Week 12
Clinical Remission based on modified Mayo Score is defined as endoscopic subscore 0 or 1 (without friability), stool frequency subscore 0 or 1, and rectal bleeding subscore 0.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit).
