Efficacy and Safety of Calcipotriene Plus Betamethasone Dipropionate Aerosol Foam in Patients With Psoriasis Vulgaris--a Randomized Phase III Study (PSO-FAST).

Abstract

INTRODUCTION:

An innovative aerosol foam formulation of calcipotriene 0.005% (Cal) plus betamethasone dipropionate 0.064% (BD) designed to improve treatment outcomes.

OBJECTIVE:

To compare the efficacy and safety of Cal/BD aerosol foam with aerosol foam vehicle in patients with psoriasis.

DESIGN:

Phase III, double-blind, randomized PSO-FAST (Cal/BD foam in PSOriasis vulgaris, a Four-week, vehicle-controlled, efficacy And Safety Trial) study recruited patients with ≥ mild severity psoriasis of the trunk and/or limbs from 27 US outpatient sites (NCT01866163). Patients were randomized (3:1) to Cal/BD foam or vehicle once-daily for 4 weeks.

PRIMARY OUTCOME:

proportion of patients at week 4 who achieved treatment success according to physician's global assessment.

SECONDARY OUTCOMES:

modified (excluding head) psoriasis area and severity index (mPASI) and patient's assessment of itch (visual analog scale). Safety was monitored by adverse events/calcium homeostasis.

RESULTS:

426 patients enrolled between June and October 2013 (Cal/BD foam, n=323; vehicle, n=103). At week 4, significantly more patients using Cal/BD foam achieved treatment success versus vehicle (53.3 versus 4.8%; OR 30.3, 95% CI 9.7,94.3; P < .001) and mean mPASI score was significantly lower for patients using Cal/BD foam than vehicle (2.0 versus 5.5; adjusted difference -3.3, P <.001). Significantly greater itch relief was observed for patients using Cal/BD foam than vehicle (P = .010 at day 3, P < .001 from day 5). Adverse drug reactions were reported in 10 Cal/BD foam patients (3.1%) and two vehicle patients (1.9%); events occurred in one patient each except application site pain (Cal/BD foam, two patients; vehicle, one patient). There were no clinically significant changes in calcium homeostasis.

CONCLUSIONS:

Cal/BD foam was efficacious, achieved rapid itch relief and was well tolerated in patients with body psoriasis. This innovative aerosol foam formulation is expected to become a valuable treatment option.
