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. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

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 and older (ADULT, OLDER_ADULT)

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
Modified Mayo Score indicating remission
Time Frame: Week 12 and Week 24
The proportion of subjects in remission at Weeks 12 and 24 in the VB-201 160mg (80 mg BID) treatment group compared to placebo group.
Week 12 and Week 24

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
Modified Mayo Score indicating response
Time Frame: Week 12 and Week 24
The proportion of subjects responding at Weeks 12 and 24 in the VB-201 160mg (80 mg BID) treatment group compared to placebo group.
Week 12 and Week 24

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Frequency of Adverse Events
Time Frame: From Baseline through safety follow up at Week 28
As measured by changes from baseline in physical exam, vital signs, ECG, concomitant medications, laboratory values.
From Baseline through safety follow up at Week 28

Time Frame: Week 12 and Week 24
The proportion of subjects in each arm with a 2-point or greater decrease in the Modified Mayo score at Weeks 12 and 24.

Time Frame: Week 12 and Week 24
Change in the modified Baron score from Baseline to Weeks 12 and 24 in the VB-201 treatment group as compared to the placebo group.
