” One and Two) were identical Phase 3 randomized, parallel, double-blind, vehicle-controlled, multi-national, multi-centre studies to evaluate the safety and efficacy of roflumilast cream 0.3%. Approximately one out of four (206 of 881) patients in DERMIS-1 and DERMIS-2 were enrolled in Canadian sites. In its Phase 3 trials, roflumilast met its primary endpoint evaluating Investigator Global Assessment (IGA) success rate vs. vehicle-treated patients. Roflumilast cream 0.3% also demonstrated statistically significant improvement over vehicle on key secondary endpoints, including Intertriginous IGA (I-IGA) Success, Psoriasis Area Severity Index-75 (PASI-75), reductions in itch as measured by the Worst Itch-Numerical Rating Scale (WI-NRS), and patient perceptions of symptoms as measured by the Psoriasis Symptoms Diary (PSD). Efficacy results for patients continuing treatment with roflumilast cream in open–label extension studies of 6– and 12–month duration were maintained throughout treatment. In all trials, roflumilast cream was generally well-tolerated.

About Roflumilast Cream

Roflumilast cream is a topical cream formulation of a PDE4 inhibitor, roflumilast. PDE4 is an intracellular enzyme that increases the production of pro-inflammatory mediators and decreases production of anti-inflammatory mediators and has been implicated in a wide range of inflammatory diseases including psoriasis, eczema, and COPD. PDE4 is an established target in dermatology, and other PDE4 inhibitors have been approved by regulatory authorities for the topical treatment of atopic dermatitis or the systemic treatment of plaque psoriasis. If approved, roflumilast cream would be the first topical PDE4 inhibitor specifically for the treatment of plaque psoriasis.
