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

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Male or female subjects, ≥18 to ≤75 years of age, who have a diagnosis of chronic plaque psoriasis for at least 6 months prior to screening;
  • Plaque psoriasis covering between 10% to 30 % of body surface area (BSA);
  • PASI severity moderate to severe, scoring at least 10 but no higher than 20.

Exclusion Criteria:

  • The subject presents with psoriasis that is predominantly guttate, erythrodermic, inverse, pustular or palmo-plantar or an unstable form of psoriasis;
  • Previously failed (due to lack of efficacy) treatment with at least one systemic biologic agent for psoriasis (e.g. ustekinumab, adalimumab, etanercept, etc);
  • The subject has not undergone wash-out periods of sufficient duration for the following treatments at Baseline: Topical psoriasis treatments: 2 weeks; Systemic (non-biologic) psoriasis treatments: 4 weeks or 5 half-lives (whichever is longer); Biologic psoriasis treatments: 8 weeks or 5 half lives (whichever is longer); Phototherapy: 4 weeks;
  • The subject anticipates getting enough ultra-violet light during the study (e.g. sunbathing; tanning salon, etc.) to cause psoriasis to improve;
  • History of cancer, with the exception of skin cancer.

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
PASI 50
Time Frame: Week 16 and Week 24
The proportion of subjects in the VB-201 160 mg (80 mg BID) treatment group who achieve at least 50% improvement from the baseline PASI score at Weeks 16 and 24 (PASI 50) compared to the proportion of PASI 50 responders in the placebo group.
Week 16 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
PASI 75
Time Frame: Week 16 and Week 24
Proportion of subjects in each of the VB-201 treatment groups and in the combined (both dose groups) VB-201 treatment groups who achieve at least 75% improvement from the baseline PASI score (PASI 75) at Weeks 16 and 24 compared to the proportion of PASI 75 responders in the placebo group.

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.

Types of outcome measures include primary outcome measure and secondary outcome measure.
