Abstract

BACKGROUND: Previous results from two phase 3 studies demonstrated efficacy and safety of fixed combination halobetasol propionate 0.01%/tazarotene 0.045% (HP/TAZ) lotion in participants with moderate-to-severe plaque psoriasis. This post hoc analysis evaluated sex-specific efficacy and safety of HP/TAZ lotion. METHODS: In two randomized, double-blind, phase 3 studies, participants were randomized (2:1) to receive HP/TAZ or vehicle lotion once daily for 8 weeks. Male and female participants were evaluated separately in this pooled analysis. Efficacy assessments included treatment success (at least 2‑grade improvement in Investigator's Global Assessment [IGA] score and score of clear/almost clear), impact on individual signs of psoriasis, and affected Body Surface Area (BSA). RESULTS: The analysis included 272 males (HP/TAZ, n=175; vehicle, n=97) and 146 females (HP/TAZ, n=101; vehicle, n=45). Significantly more participants achieved overall treatment success at week 8 with HP/TAZ versus vehicle in both male (38.4% vs 9.8%) and female (44.5% vs 9.9%) subgroups (P<0.001, both). Erythema, plaque elevation, and scaling were also reduced by week 8 in both males and females, with significantly more HP/TAZ-treated participants achieving at least 2‑grade improvement in each sign of psoriasis than vehicle-treated participants (P<0.001 each, both groups). Mean reductions in affected BSA were significantly greater with HP/TAZ versus vehicle lotion in both males and females (P≤0.001, both). The most frequent treatment-related adverse events were contact dermatitis, pruritis, and application site pain (each 4.0%) in females and contact dermatitis (7.6%) in males. CONCLUSION: HP/TAZ lotion was highly effective and safe in both males and females with moderate-to-severe psoriasis over 8 weeks of once-daily use.
