RESULTS ◾ The analysis population included 146 female participants (HP/TAZ lotion, n=101; vehicle, n=45) and 272 male participants (HP/TAZ lotion, n=175; vehicle, n=97) Efficacy ◾ At week 8, the percentage of female and male participants with treatment success was significantly greater in the HP/TAZ group than the vehicle group; significant differences were observed by week 2 and maintained posttreatment (Figure 1) ◾ Significantly more HP/TAZ‑treated female and male participants achieved a ≥2‑grade improvement in erythema, plaque elevation, and scaling at week 8 compared with the vehicle group (Figure 2) ◾ Females and males treated with HP/TAZ lotion had a significantly greater reduction from baseline in affected BSA at week 8 versus the vehicle group, with significant differences observed as early as week 4 for females and week 2 for males; significant differences were sustained posttreatment for both females and males (Figure 3) Safety ◾ The most frequently reported treatment‑related TEAEs in the female HP/TAZ group were contact dermatitis, pruritis, and application site pain (all 4.0%); pruritis was the most common TEAE deemed related to vehicle treatment (7.0%) ◾ For males in the HP/TAZ group, the most frequently reported treatment‑related TEAE was contact dermatitis (7.6%); in the vehicle group, no TEAEs deemed related to treatment occurred in >1 male CONCLUSIONS ◾ Halobetasol propionate 0.01% and tazarotene 0.045% lotion was associated with significant reductions in disease severity in female as well as male patients with moderate‑to‑severe psoriasis, with good tolerability and safety over 8 weeks of once‑daily use REFERENCES 1.
