Clinical, patient and estimated cost benefits of proactive management versus reactive management with calcipotriol/betamethasone dipropionate foam for the treatment of plaque psoriasis in Finland

Background Proactive management of plaque psoriasis with twice-weekly topical calcipotriol/betamethasone dipropionate (Cal/BD) foam has a demonstrated clinical benefit in preventing disease relapse compared to reactive management, where Cal/BD foam is only given as rescue therapy once-daily for four weeks after relapse. The impact of proactive management with Cal/BD foam on a wider range of clinical responses is not yet known, nor is its potential cost-effectiveness in the healthcare system of Finland. Methods This study involved a post-hoc analysis exploring the clinical and patient-reported benefits of proactive versus reactive management with Cal/BD foam observed in the PSO-LONG trial (NCT02899962). A range of response criteria based on modified psoriasis area and severity index (mPASI) and dermatology life quality index (DLQI) were analyzed, and the cost-effectiveness of proactive versus reactive management was estimated in a Finnish healthcare setting. Results and conclusion The analysis found a consistent clinical benefit of proactive management compared to reactive management on all response criteria, and a markedly lower cost-per-responder for the response criteria of mPASI 75, mPASI <= 2 and DLQ1 <= 1. The analysis was robust to sensitivity analyses on key inputs and demonstrates the cost and clinical benefits of proactive over reactive management of plaque psoriasis with Cal/BD foam in the Finnish healthcare setting.

Automated summary

The study found that proactive management with Cal/BD foam showed consistent clinical benefits compared to reactive management on all response criteria, and resulted in significantly lower cost-per-responder for mPASI 75, mPASI <= 2, and DLQI <= 1 criteria. The analysis demonstrated the cost-effectiveness and clinical benefits of proactive management of plaque psoriasis with Cal/BD foam in the Finnish healthcare setting.
