Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Study Type

Study Type

Describes the nature of a clinical study. Study types include interventional studies (also called clinical trials), observational studies (including patient registries), and expanded access.

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)

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  • 18 years of age or older, at the time of signing the informed consent
  • Participants with clinical diagnosis of plaque psoriasis, including lesion(s) in intertriginous area(s) and stable disease in intertriginous areas for at least 3 months prior to the study
  • An iPGA score of 2 (mild), 3 (moderate), or 4 (severe) at screening and baseline
  • Female subjects of child bearing potential who are engaging in sexual activity that could lead to pregnancy agree to follow the specified contraceptive guidance throughout the study
  • Negative pregnancy test at Baseline (Day 1)
  • Capable of giving written informed consent

Exclusion Criteria:

  • Diagnosis of a type of psoriasis other than plaque psoriasis
  • Any sign of infection of any of the psoriatic lesions
  • Concurrent significant dermatologic or inflammatory condition other than plaque psoriasis that, in the Investigator's opinion, would make it difficult to interpret data or assessments during the study
  • History of or ongoing serious illness or medical, physical, or psychiatric condition(s) that, in the Investigator's opinion, may interfere with participation in the study and ability to understand and give informed consent
  • History of sensitivity to the study product, or components thereof or a history of drug or other allergy that, in the opinion of the Investigator or Medical Monitor, contraindicates participation in the study
  • Previous known participation in a clinical study with tapinarof (previously known as GSK2894512 and WBI-1001); previous or current use of VTAMA® (Tapinarof) Cream 1%
  • Use of any prohibited medication or procedure within the indicated period before the baseline visit including other investigational product within 30 days or 5 half-lives of the investigational product (whichever is longer)
  • UV light therapy or prolonged exposure to natural or artificial sources of UV radiation (e.g., phototherapy, tanning beds/booths, or therapeutic sunbathing) within 4 weeks prior to the Baseline

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 Who Achieve an Intertriginous PGA (iPGA) Score of Clear (0) or Almost Clear (1) With a ≥ 2-grade Improvement
Time Frame: from Baseline to Week 12
Intertriginous Physician Global Assessment (iPGA) is a clinical tool for assessing the current state/severity of a subject's psoriasis in the intertriginous areas at a given timepoint. It is a static 5-point assessment of plaque qualities on the clinical characteristics of erythema, scaling, and plaque thickness/elevation within the intertriginous areas. The iPGA ranges from 0 to 4, and is calculated as Clear (0), Almost Clear (1), Mild (2), Moderate (3), and Severe (4). Higher iPGA scores represent more severe disease.
from Baseline to 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.
