Pfizer
  Purpose
The purpose of this study is to evaluate the safety and efficacy of AN2728 Ointment B, 2.0% and 0.5%, compared to Ointment Vehicle B, applied once or twice daily for 12 weeks, in the treatment of plaque type psoriasis

Condition Intervention Phase
Psoriasis Drug: AN2728 Drug: Placebo Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Double-Blind,Randomized, 12 Week, Bilateral Study of the Safety and Efficacy of AN2728 Ointment B, 2% and 0.5%, Versus Ointment B Vehicle in the Treatment of Patients With Plaque Type Psoriasis

Primary Outcome Measures:
  • Percentage of Participants With Greater Decrease In Overall Target Plaque Severity Score (OTPSS): Ointment (2% Twice Daily), Vehicle [ Time Frame: Day 42 ]
    OTPSS is a scale to assess plaque severity. Each target plaque was scored by the investigator on severity scale ranging from 0 (no plaque) to 8 (very severe plaque), where higher score indicates more severity of a plaque. In this outcome measure, percentage of participants with reduced OTPSS in ointment (2% twice daily) treated plaque versus (vs.) vehicle treated plaque and percentage of participants with reduced OTPSS in vehicle treated plaque versus ointment (2% twice daily) treated plaque respectively at Day 42 are reported.


Secondary Outcome Measures:
  • Percentage of Participants With Greater Decrease In OTPSS: Ointment (0.5 % Once Daily, 0.5% Twice Daily and 2% Once Daily), Vehicle [ Time Frame: Day 42 ]
    OTPSS is a scale to assess plaque severity. Each target plaque was scored by the investigator on severity scale ranging from 0 (no plaque) to 8 (very severe plaque), where higher scores indicated more severity of a plaque. In this outcome measure, percentage of participants with reduced OTPSS in ointment (0.5 % once daily, 0.5% twice daily and 2% once daily) treated plaque versus vehicle treated plaque and percentage of participants with reduced OTPSS in vehicle treated plaque versus ointment (0.5 % once daily, 0.5% twice daily and 2% once daily) treated plaque respectively at Day 42 are reported.

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.

Criteria

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

  • 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)
