  Purpose

Corticosteroids are one of the mainstays of treatment for subjects with corticosteroid-responsive dermatoses such as psoriasis. This study has been designed to determine and compare the efficacy and safety of a formulation of 122-0551 versus the corresponding Vehicle in subjects with stable plaque psoriasis after twice daily dosing for 14 consecutive days.

Primary Outcome Measures:
  • Change in Overall Disease Severity (ODS) Score [ Time Frame: baseline and Day 15 (End of Study - EOS) ] [ Designated as safety issue: No ]
    The proportion of subjects with ODS "treatment success" at EOS where EOS is the subject's last completed visit. "Treatment success" is defined as an ODS of 0 or 1. ODS is measured on a 5-point scale: 0 = clear; 1 = almost clear; 2 = mild; 3 = moderate; 4 = severe/very severe.


Secondary Outcome Measures:
  • ODS "treatment success" at Day 8 and Day 15 [ Time Frame: baseline, Day 8, and Day 15 ] [ Designated as safety issue: No ]
    The proportion of subjects with ODS "treatment success" at Day 8 and Day 15.

  • ODS "improved" at Day 8 and Day 15 [ Time Frame: baseline, Day 8, and Day 15 ] [ Designated as safety issue: No ]
    The proportion of subjects rated "improved" with respect to ODS at Days 8 and 15. "Improved" is defined as at least a 2 grade decrease in ODS score relative to baseline.

  • "Treatment success" for clinical signs and symptoms of psoriasis [ Time Frame: baseline, Day 8 and Day 15 ] [ Designated as safety issue: No ]
    The proportion of subjects rated "treatment success" for each of the clinical signs and symptoms of psoriasis (scaling, erythema, plaque elevation) at Days 8 and 15.

  • "Improved" for clinical signs and symptoms of psoriasis [ Time Frame: baseline, Day 8 and Day 15 ] [ Designated as safety issue: No ]
    The proportion of subjects rated "improved" for each of the clinical signs and symptoms of psoriasis (scaling, erythema, plaque elevation, pruritus) at Days 8 and 15.

  • Change in % body surface area (BSA) with psoriasis [ Time Frame: baseline, Day 8 and Day 15 ] [ Designated as safety issue: No ]
    Changes in % BSA with active psoriasis in the Treatment Area at Days 8 and 15.
