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

Genders Eligible for Study

Description

Inclusion Criteria:

  • Subjects are male or non-pregnant female; 18 years of age at the time of screening.
  • Subjects provide Institutional Review Board (IRB) approved written informed consent for participating in this study.
  • Subjects have a clinical diagnosis of stable plaque psoriasis involving a minimum of 20% body surface area and an Overall Disease Severity (ODS) score on the designated treatment area of at least 3 as determined by the evaluating investigator.
  • Subjects are willing and able to apply the study medication as directed, comply with study instructions and commit to all follow-up visits for the duration of the study.
  • Women of childbearing potential (WOCBP) must have a negative urine pregnancy test at the Screening (Part B) and Baseline Visits and agree to use an effective form of birth control for the duration of the study (abstinence, stabilized on oral contraceptives or contraceptive patches for at least three months, implant, injection, IUD, NuvaRing®, condom and spermicidal or diaphragm and spermicidal). Abstinence is an acceptable form of birth control for subjects who are not sexually active. Subjects who become sexually active during the trial must agree to use an effective, non-prohibited form of birth control for the duration of the study.

Exclusion Criteria:

  • Subjects have spontaneously improving or rapidly deteriorating plaque psoriasis, or have guttate, pustular, erythrodermic or other non-plaque forms of psoriasis.
  • Subjects have a physical condition which, in the Investigator's opinion, might impair evaluation of plaque psoriasis, adrenal axis function (e.g., Addison's Disease, Cushing's Syndrome) or which exposes the subject to an unacceptable risk by study participation.
  • Subjects have used any phototherapy (including laser), photo-chemotherapy or systemic psoriasis therapy including methotrexate, retinoids, cyclosporine or biologics within 30 days prior to the initiation of study medication treatment.
  • Subjects have used systemic corticosteroids (including oral or intramuscular) or topical, inhaled or intranasal corticosteroids within 30 or 14 days, respectively, prior to Part B of the Screening Visit and/or subjects have used systemic or topical corticosteroids between the Screening Visit and the initiation of treatment.
  • Subjects have had prolonged exposure to natural or artificial sources of ultraviolet radiation within 30 days prior to the initiation of treatment or are intending to have such exposure during the study that is thought by the Investigator to likely modify the subject's disease.
  • Subjects have used topical psoriatic therapy including tar, anthralin, retinoids, vitamin D analogs (e.g., Dovonex®) within 14 days prior to the initiation of study medication treatment.
  • Subjects have used emollients/moisturizers on areas to be treated within one day prior to the initiation of study medication treatment.
  • Subjects are currently using lithium or plaquenil.
  • Subjects are currently using a beta-blocking medication (e.g., propanolol) or angiotensin converting enzyme (ACE) inhibitors at a dose that has not been stabilized, in the opinion of the Investigator.
  • Subjects have a history of sensitivity to any of the ingredients in the study medication.
  • Subjects are pregnant, nursing or planning a pregnancy during the study period.
  • Subjects are currently enrolled in an investigational drug or device study.
  • Subjects have received an investigational drug or an investigational device within 30 days prior to screening.
  • Subjects have been previously enrolled in this study and treated with the study medication.
  • Subjects have irregular sleep schedules or work night shifts (cortisol levels exhibit physiological diurnal variation).
  • Subjects have a screening CST with a post 30-minute stimulation cortisol level of ≤ 18 µg/dL.

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
Adrenal Suppression Potential
Time Frame: After 1-2 weeks dose
Hypothalamic Pituitary-Adrenal (HPA)-Axis responses to Cosyntropin Stimulation Testing (CST) were dichotomized to normal and abnormal. An abnormal HPA Axis response (HPA Suppression) was defined as a 30-minute post-stimulation serum cortisol level of ≤18 μg/dL at the end of treatment.
After 1-2 weeks dose
Pharmacokinetic Properties (Cmax)
Time Frame: Day 8
Comparison of PK results (peak concentration in plasma [Cmax]) between the two Treatment Groups will be conducted following the last application of the medication on Day 8.
Day 8
Pharmacokinetic Properties (Tmax)
Time Frame: Day 8
Comparison of PK results (time to peak concentration [Tmax]) between the two Treatment Groups will be conducted following the last application of the medication on Day 8.
Day 8
Pharmacokinetic Properties (AUC)
Time Frame: Day 8
Comparison of PK results (area under the curve [AUC] from time 0 to infinity) between the two Treatment Groups will be conducted following the last application of the medication on Day 8.
Day 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
Changes in Disease Severity (Success)
Time Frame: Day 15
Overall disease severity (ODS) will be recorded at baseline, Day 8, and Day 15 on a 0 (clear) to 4 (severe/very severe) point scale. ODS evaluations will be dichotomized to "success" and "failure" with success defined as a grade of 1 or 0 at the end of treatment (EOT).
Day 15
Number of Subjects Whose Signs of Psoriasis Was Designated "Success"
Time Frame: Day 15
Signs of psoriasis including scaling, erythema, and plaque elevation will be recorded at baseline, Day 8, and Day 15 on a 0 (clear) to 4 (severe/very severe) point scale. Each of the signs of psoriasis will be dichotomized to a) "success" and "failure" with success defined as a grade of 1 or 0 at the End of Treatment (EOT; i.e., the visit at which psoriasis has cleared [Day 8 or Day 15] or end of the assigned treatment period).
Day 15
