INTRODUCTION: Patients with psoriasis and low body surface area (BSA) involvement often experience substantially reduced quality of life and may be candidates for topical therapies. Fixed-combination halobetasol propionate (0.01%) and tazarotene (0.045%) lotion (HP/TAZ) vs vehicle lotion was evaluated in participants with 3% to 5% BSA involvement.
METHODS: In two phase 3, multicenter, double-blind, vehicle-controlled, 8-week studies (ClinicalTrial.gov identifiers: NCT02462070/NCT02462122), adults with moderate/severe investigator’s global assessment (IGA) score were randomized 2:1 to once-daily HP/TAZ or vehicle. Pooled post hoc analyses included participants with baseline BSA involvement of 3% to 5%. Measures included treatment success (≥2-grade IGA reduction, clear/almost clear score), reduction in affected BSA, and clinically meaningful improvement (reduction) of ≥4 points on dermatology life quality index (DLQI).
RESULTS: Of 418 participants, 232 had baseline BSA involvement of 3% to 5% (HP/TAZ, n=149; vehicle, n=83). At week 8, 42.7% of HP/TAZ-treated participants achieved treatment success, compared with 11.4% of vehicle-treated participants (P< .001). Participants experienced significantly greater reductions in affected BSA at week 8 with HP/TAZ (-36.0%) vs vehicle (-1.6%; P< .001). Larger proportions experienced clinically meaningful DLQI improvements at week 8 with HP/TAZ (64.2%) vs vehicle (47.4%; P< .05). More participants achieved a ≥2-grade improvement in plaque elevation and scaling with HP/TAZ vs vehicle (each comparison, P< .001). Serious adverse events and discontinuations due to treatment-emergent adverse events were rare.
CONCLUSIONS: In participants with plaque psoriasis and BSA involvement of 3% to 5%, HP/TAZ provided significantly improved effectiveness after 8 treatment weeks vs vehicle lotion, with clinically meaningful improvements in quality of life.
