ABSTRACT
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.
ABSTRACT
Psoriasis is a chronic, immune-mediated inflammatory disease characterized by localized scaling and plaques associated with itching and pain. In some cases, topical therapies are effective to treat mild to moderate psoriasis. Topical agents can be used concomitantly with other treatments for moderate and severe or treatment-resistant psoriasis. Patient adherence to medication regimens remains a major challenge in therapy, especially with topical agents, for which adherence can be affected by the amount of time needed for application, the treatment formulation, cost, and cosmetic characteristics. This study was conducted to obtain feedback from patients clinically diagnosed with psoriasis regarding their satisfaction following once-daily topical application of the fixed combination calcipotriene (Cal) 0.005% and betamethasone dipropionate (BD) 0.064% foam for 15 days. Patients completed a 13-question online survey. In this community-based setting of patients with mild to severe psoriasis, patients were satisfied with Cal/BD foam after 15 days of use; 94% were satisfied or highly satisfied with symptom relief. Most of the patients (88%) were satisfied with how Cal/BD foam felt on their skin. After 15 days of use, 94% of patients would recommend Cal/BD foam to other patients with psoriasis, with 73% being very likely to do so. These findings may have important implications for optimizing medical decision-making, treatment adherence, and health outcomes in clinical practice. The cosmetic acceptability of the fixed combination Cal/BD foam formulation and patient satisfaction may make Cal/BD aerosol foam a more acceptable topical treatment than other currently available vehicles for patients with plaque psoriasis.
