CLINICAL COMMENTARY � Unlike real-world use, participants in this study were required to continue administration of HP/TAZ for 8 continuous weeks—even if they had clearance of active psoriasis—which may have contributed to increased levels of irritation in the mild subgroups versus the overall population � Treatment-emergent irritation may potentially be addressed in the clinic by: • Recommending that patients temporarily interrupt drug use (eg, drug holiday) and resume application of the lotion once irritation signs/ symptoms have subsided • Encouraging the use of moisturizers before resuming treatment Halobetasol Propionate 0.01%/Tazarotene 0.045% Lotion for the Treatment of Plaque Psoriasis in Patients with Mild Scaling and Mild Plaque Elevation � In the mild plaque elevation group, those treated with HP/TAZ demonstrated significantly greater improvements in signs of psoriasis at week 8 versus vehicle (Figure 3) • A numerically higher treatment success rate was observed with HP/TAZ versus vehicle at week 8 in the mild plaque elevation group, with significance reached 4 weeks posttreatment (Figure 2) • Lack of statistical separation of HP/TAZ from vehicle for treatment success and BSA reduction may be partly attributed to the small population and/or favorable response to the vehicle formulation FIGURE 1.

CONCLUSIONS � In two pooled phase 3 studies, HP 0.01%/TAZ 0.045% lotion was efficacious and well tolerated following 8 weeks of treatment among participants with mild plaque elevation and mild scaling � Results were generally similar to the overall study population, indicating that HP/TAZ lotion is a viable treatment option for patients with plaque psoriasis who have mild signs of scaling and plaque elevation, regardless of their IGA severity at baseline REFERENCES 1.
