Abstract

BACKGROUND:

There is a need for the development of novel non-steroidal topical drugs for the treatment of psoriasis.

OBJECTIVE:

To assess the efficacy and safety of topical 1.0% WBI-1001 in patients with mild to moderate plaque psoriasis.

METHODS:

A total of 61 patients with 1-10% body surface area (BSA) covered with plaque psoriasis and a physician's global assessment score (PGA) of 2-4 were randomized (2:1) to receive either 1% WBI-1001 in a cream formulation or placebo, applied twice daily for 12 weeks. Efficacy was evaluated using PGA, BSA and Psoriasis Area and Severity Index (PASI). The primary endpoint was the change from baseline (Day 0) in PGA at week 12.

RESULTS:

The improvement in PGA at week 12 was 62.8% for patients randomized to WBI-1001 when compared with 13.0% for patients randomized to placebo (P<0.0001). At week 12, the proportion of patients who achieved a PGA of clear or almost clear and the mean improvement in BSA were 67.5% and 79.1%, respectively, for patients randomized to WBI-1001, when compared with 4.8% (P<0.0001) and an increase of 9.4% (P<0.0001), respectively, for patients randomized to placebo. More application site adverse drug reactions were observed in patients randomized to WBI-1001 than in those randomized to placebo. These adverse drug reactions were all mild or moderate in intensity.

CONCLUSION:

Topical WBI-1001 induces rapid and significant improvement in patients with plaque psoriasis.
