Matching-Adjusted Indirect Comparison of Long-Term Efficacy and Safety Outcomes for Calcipotriol Plus Betamethasone Dipropionate Foam Versus Halobetasol Proprionate Plus Tazarotene Lotion in the Treatment of Plaque Psoriasis

Dermatol Ther (Heidelb). 2022 Oct 12. doi: 10.1007/s13555-022-00824-9. Online ahead of print.

ABSTRACT

INTRODUCTION: To date, there have been no head-to-head clinical studies comparing calcipotriol 0.005% plus betamethasone dipropionate 0.064% (Cal/BD) aerosol foam and halobetasol propionate 0.01% plus tazarotene 0.045% (HP/Taz) lotion for the treatment of plaque psoriasis. However, the efficacy of 4 weeks of Cal/BD foam and 8 weeks of HP/Taz lotion has been compared using a matching-adjusted indirect comparison (MAIC) approach. Here, we compare the efficacy and safety of Cal/BD foam and HP/Taz lotion for up to 52 weeks.

METHODS: An unanchored MAIC was conducted using individual patient data from the PSO-LONG Cal/BD foam trial and a 52-week, open-label phase 3 study of HP/Taz lotion (NCT02462083). Key outcomes of interest were Physician’s Global Assessment (PGA) success (PGA 0/1 with ≥ 2-point improvement) after 4 or 8 weeks of open-label therapy; the proportion of patients who had body surface area affected (BSA) ≤ 3 after open-label therapy who maintained BSA ≤ 3 to week 52; and adverse events (AEs).

RESULTS: After matching, patients were statistically significantly more likely to have PGA success after 4 weeks of Cal/BD foam than after 8 weeks of HP/Taz lotion (84.5% versus 54.4%; p < 0.01). At week 52, 92.5% and 92.4% of patients receiving proactive and reactive Cal/BD foam, respectively, maintained BSA ≤ 3, compared with 49.3% of those treated with HP/Taz lotion (both p < 0.01). Treatment-related AEs, AEs leading to withdrawal, and AEs associated with drug application (dermatitis, application site pain, and pruritus) were significantly rarer with Cal/BD foam than with HP/Taz lotion (all p < 0.01).

CONCLUSIONS: Cal/BD aerosol foam demonstrated significantly greater efficacy than HP/Taz lotion, and had a more favorable safety profile, compared with HP/Taz lotion, for up to 52 weeks. Proactive Cal/BD foam maintenance therapy and reactive use of Cal/BD foam following relapse both had significant advantages over HP/Taz lotion.
