This is a multi-center, randomized, double-blind bilateral design. Patients will apply the test articles, AN2728 Ointment, 5%, and Ointment Vehicle twice daily. 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.
The purpose of the study is to determine the safety and efficacy of AN2728 Ointment, 5%, compared to Ointment Vehicle in the treatment of plaque type psoriasis.
