Indirect Comparison of Cal/BDP PAD-Cream vs Cal/BDP Foam in Patients with Plaque Psoriasis Meeting the Rule of Tens.

INTRODUCTION

Calcipotriol and betamethasone dipropionate (Cal/BDP) PolyAphron dispersion (PAD) cream and Cal/BDP foam have demonstrated superior efficacy to Cal/BDP gel in patients with plaque psoriasis exhibiting a more severe profile defined by the Rule of Tens in different studies. However, its comparative efficacy in this subgroup of patients needs to be studied.

METHODS

An indirect treatment comparison (ITC) using individual patient data for Cal/BDP PAD cream and available aggregated data for Cal/BDP foam was conducted for three outcome measures: Physician's Global Assessment (PGA) success, modified Psoriasis Area and Severity Index 75 (mPASI75), and Dermatology Life Quality Index (DLQI) satisfaction. Bucher's method was used for the ITC base case, and alternative analyses were performed using an anchored matching-adjusted indirect comparison (MAIC). Odds and risk ratios were calculated for each outcome.

RESULTS

After adjustment to the Rule of Tens, Cal/BDP PAD cream showed no differences vs. Cal/BDP foam in the three outcomes. Similar results were found for the MAIC scenarios after population matching, supporting the validity of the results.

CONCLUSION

In this ITC analysis, no significant differences in the clinical efficacy of Cal/BDP PAD cream and Cal/BDP foam in patients with plaque psoriasis meeting the Rule of Tens were observed considering their recommended treatment durations.
