Challenges in Psoriatic Disease Addressed by Fixed-Combination Halobetasol Propionate 0.01% and Tazarotene 0.045% Lotion.

Objective: The fixed-dose corticosteroid/retinoid combination halobetasol propionate (0.01%) and tazarotene (0.045%) lotion (HP/TAZ) is approved for topical treatment of plaque psoriasis in adults. In addition to its current indication for plaque psoriasis, a growing body of clinical data suggests that HP/TAZ may be a beneficial therapy for palmoplantar and scalp psoriasis. Here, we discuss the efficacy and safety of HP/TAZ in various psoriatic phenotypes and related conditions. Methods: Three studies (one post-hoc analysis, two open-label reports) of HP/TAZ were identified for this discussion. Results: A post-hoc analysis demonstrated that once-daily HP/TAZ was associated with sustained efficacy and clinically meaningful quality-of-life improvements in participants with psoriatic disease who had low quality of life and 3% to 5% affected body surface area at baseline. In open-label reports, HP/TAZ was associated with improvement in scalp psoriasis measures, as well as quality of life. Additionally, HP/TAZ was efficacious in patients with palmoplantar psoriasis and in one report of a patient with palmoplantar pustulosis. Limitations: Limitations include the small sample sizes of open-label reports of HP/TAZ; larger studies are needed to confirm findings. Conclusion: Taken together, this evidence suggests that HP/TAZ may address unmet needs in psoriatic disease as a therapy for patients with all levels of psoriasis severity who experience daily challenges associated with their disease and that it may be a candidate for treating a variety of forms of psoriasis.
