Plaque Psoriasis | Drug: Prurisol Drug: Placebo | Phase 2 |
The total duration of study participation for an individual subject is approximately 112 days (16 weeks) consisting of a Screening visit, followed within 21 days by Randomization and a Treatment Period of 84 days, and a Follow-up Period of 28 days after the last day of study drug treatment. A window of ± 3 days will be considered acceptable for conduct of each scheduled visit following the first visit.
This study will require eight (8) scheduled subject visits:
x Visit 1: Screening (Up to Day 21) x Visit 2: Baseline (Day 0) x Visit 3: Day 14 Interim (± 3 days) x Visit 4: Day 28 Interim (± 3 days) x Visit 5: Day 42 Interim (± 3 days) x Visit 6: Day 56 Interim (± 3 days) x Visit 7: Day 84 End of Treatment/Unscheduled/ET (± 3 days) x Visit 8: Day 112 Follow-up (± 3 days)

- The primary efficacy endpoint will be the percentage of subjects with ≥ 2 point improvement in IGA rating as defined by visual inspections of patient lesions [ Time Frame: 84 days ]
- The Secondary efficacy endpoints are the percentage of subjects in each treatment group with:≥ 2 point improvement in IGA at 28 days [ Time Frame: 28 days ]
- The Secondary efficacy endpoints are the percentage of subjects in each treatment group with: ≥ 2 point improvement in IGA at 56 days [ Time Frame: 56 Days ]
- The Secondary efficacy endpoints are the percentage of subjects in each treatment group with: ≥1 point improvement in Scaling Score of Target Lesion at 28 days [ Time Frame: 28 Days ]
- The Secondary efficacy endpoints are the percentage of subjects in each treatment group with: ≥1 point improvement in Scaling Score of Target Lesion at 56 days [ Time Frame: 56 Days ]
- The Secondary efficacy endpoints are the percentage of subjects in each treatment group with: ≥1 point improvement in Scaling Score of Target Lesion at 84 days [ Time Frame: 84 Days ]

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Male or non-pregnant female adults aged 18 years with a clinical diagnosis of stable (at least 6 months) plaque psoriasis, not including scalp or intertriginous areas.
-
The extent of psoriasis must meet all of the following three (3) criteria:
- Total Body Surface Area (BSA) affected by plaque psoriasis of 10% to 20% inclusive
- Investigator's Global Assessment (IGA) score of the severity of psoriasis of 2 or 3 (5- point ordinal scale)
- Identification of a target psoriatic lesion with a score of 3 on the Target Lesion Assessment scale (5-point ordinal scale) for Scaling. (Other psoriatic lesions may have lower scaling scores.)
- Females of reproductive potential must not be pregnant
- Female subjects with reproductive potential, if sexually active, must agree to use reliable means of contraception
- The subject must agree to avoid prolonged exposure to the sun and avoid the use of tanning booths or other ultraviolet light sources during the study.
- The subject must provide signed and dated written informed consent to participate in the clinical study.
Exclusion Criteria:
- 1. Females of reproductive potential who are not using reliable contraception.
- Presence of any non-psoriatic uncontrolled (in the Investigator's medical opinion) systemic disease. i
- Unstable forms of psoriasis, e.g. guttate, erythrodermic, exfoliative, palmoplantar, nail, or pustular.
- Use within 6 months of biologic treatment for psoriasis
- Use within 24 months of chemotherapy or radiation therapy.
- Use within 2 months of any systemic immunosuppressive therapy.
- Use within 1 month of (1) systemic corticosteroids, (2) systemic antibiotics, (3) systemic antipsoriasis treatments (e.g. methotrexate, corticosporin, hydroxyurea), (4) PUVA therapy, (5) UVB, (6) systemic anti-inflammatory treatment.
- Use within 2 weeks of topical antipsoriasis drugs or topical corticosteroids or topical retinoids.
- Presence of a condition (e.g., history of frequent consumption of substantial quantities of alcohol, or an untreated psychiatric condition) that makes it unlikely that the requirements of the protocol will be completed.
- History of any previous use of a Tumor Necrosis Factor (TNF) blocker or other immunomodulating drug as therapy for psoriasis within the 6 months prior to screening.
- History of any allergic reaction to any formulation of abacavir.
- Previous treatment with any abacavir-containing product, e.g., Ziagen®, Epzicom®, or Trizivir®.
