Detailed Description:
This is a multicenter, randomized, double-blind, vehicle-controlled, bilateral design. Patients will apply both test article AN2728 Ointment B (0.5% or 2%), and Ointment B Vehicle twice daily for 12 weeks. The assigned study medication will be applied to two comparable treatment targeted plaques identified at baseline. One test article will be applied to one plaque and the other test article to an anatomically distinct plaque. All efficacy evaluations will be measured from only the two plaques identified at the baseline visit.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  • Male or female >18 years of age at time of enrollment
  • Clinical diagnosis of stable plaque type psoriasis
  • Two target plaques of similar severity meeting the following criteria:

    • 5 cm2 and ≤ 100 cm2, computed by multiplying the greatest diameter of the plaque by the diameter of the plaque perpendicular to the greatest diameter Bilaterally located (right/left) plaques on the arms or plaques located on the trunk. Plaques located on the trunk must be separated by at least 10 cm Overall target plaque severity score (OTPSS) of 2-4 (mild to moderate) with no more than a 1 point difference in the scores of the two target plaques
  • Willing and able to apply study drug as directed, comply with study instructions and commit to all follow-up visits
  • Ability to understand, agree to and sign the study Informed Consent Form (ICF) prior to initiation of any protocol related procedures

Exclusion Criteria:

  • Any dermatological conditions, disease state or physical condition that could interfere with clinical evaluations or might expose the patient to an unacceptable risk by study participation
  • Any underlying disease(s) or other dermatological conditions that require the use of exclusionary topical or systemic therapy (see below)
  • Clinically significant, abnormal Screening laboratory results (unless approved by the medical monitor)
  • Known sensitivity to any of the components of the study medication
  • Spontaneously improving or rapidly deteriorating psoriatic plaques or pustular/exfoliative, guttate, erythrodermic or other non-plaque form of psoriasis
  • Concomitant use of topical or systemic therapies that might alter the course of psoriasis
  • Females of child bearing potential. Females must be post-menopausal (based on FSH levels) or surgically sterile (hysterectomy or bilateral oophorectomy)
  • Washout periods for exclusionary therapies:

Oral retinoids: 8 weeks Non-retinoid systemic drugs that might alter the course of psoriasis: 4 weeks Psoralens with UV-A (PUVA): 4 weeks Ultraviolet-B (UVB) therapy: 4 weeks Topical drugs that might alter the course of psoriasis: 2 weeks Use of emollients/moisturizers on area(s) to be treated: 2 days prior to Baseline visit

  • AIDS or AIDS-related illness
  • Concurrent participation in another drug or device research study or within 30 days prior to enrollment
  • Use of lithium- or hydroxychloroquine-containing products (e.g., Plaquenil)
  • Use of a beta-blocking medication (e.g., Propranolol) if the dose has not been stabilized for at least 3 months
  • Use of AN2728 in a previous clinical trial
