Encore Dermatology, Inc. Announces Phase 2 Safety Data Demonstrating Lower Systemic Drug Exposure With Impoyz™ (clobetasol propionate) Cream, 0.025% Compared to Temovate® (clobetasol propionate) Cream, 0.05%
Encore Dermatology, Inc. today announced the publication of a Phase 2, open-label study in SKIN The Journal of Cutaneous Medicine. Subjects treated with Impoyz (clobetasol propionate) Cream, 0.025% showed significantly lower mean post-treatment clobetasol propionate plasma concentrations versus the subjects treated with Temovate® (clobetasol propionate) Cream, 0.05% (56.3 vs 152.5 pg/mL, P=0.014). Both treatment groups evidenced similar improvements in global psoriasis severity as measured by improvements in the Investigator’s Global Assessment (IGA) from baseline to Day 15. As a result, compared with traditional-dose formulations of clobetasol propionate (0.05%), this data suggests that Impoyz Cream may provide a better safety profile without compromising efficacy.

Additionally, a lower proportion of subjects in the Impoyz Cream group (12.5%) experienced HPA axis suppression compared to those in the Temovate Cream group (36.4%), although this did not reach statistical significance (P=0.086).
“Impoyz Cream is the first topical clobetasol offering an alternative to the traditional 0.05% clobetasol concentrations, allowing dermatology providers greater flexibility when prescribing high-potency topical corticosteroids,” said Bob Moccia, president and CEO of Encore Dermatology.
The study is a randomized, multicenter, multidose, comparator controlled, open-label study in 50 subjects with moderate to severe plaque psoriasis involving 20% to 50% of the body surface area (BSA) at baseline, not including the face, scalp, groin, axillae, and other intertriginous areas. Subjects were randomized (1:1) to treatment with Impoyz Cream or Temovate Cream and instructed to apply study product twice daily for 15 days. The primary safety assessments were the potential for HPA axis suppression and the mean post-treatment clobetasol propionate plasma concentrations before and after the 15-day treatment period.

Important Safety Information for Impoyz TM (clobetasol propionate) Cream, 0.025%
Topical corticosteroids, including IMPOYZ Cream, can cause reversible hypothalamic-pituitary-adrenal (HPA) axis suppression with the potential for glucocorticosteroid insufficiency. This may occur during treatment or after withdrawal of treatment. This may require that patients be evaluated periodically for evidence of HPA axis suppression. Factors that predispose to HPA axis suppression include use of high-potency steroids, large treatment surface areas, prolonged use, use of occlusive dressings, altered skin barrier, liver failure, and young age. If HPA axis suppression occurs, gradually withdraw the drug, reduce frequency of application, or substitute with a less potent corticosteroid. If signs and symptoms of withdrawal occur, systemic corticosteroids may be required. Recovery of HPA axis function is generally prompt and complete upon discontinuation of topical corticosteroids. Although rare, systemic effects of topical corticosteroids may manifest as Cushing’s syndrome, hyperglycemia, and glucosuria.
Pediatric patients may be more susceptible to systemic toxicity because of their larger skin surface to body mass ratios.
Local adverse reactions from topical corticosteroids may be more likely to occur with occlusion, prolonged use, or use of higher-potency corticosteroids. Some local adverse reactions may be irreversible.
Use an appropriate antimicrobial agent if a skin infection is present or develops. If appropriate, discontinue use of IMPOYZ Cream.
Allergic contact dermatitis with corticosteroids is usually diagnosed by observing failure to heal rather than noting a clinical exacerbation.
The adverse reaction that occurred in at least 1% of subjects treated with IMPOYZ Cream and at a higher incidence than in subjects treated with vehicle cream was application site discoloration (2% versus 1%). Less common local adverse events occurring in < 1% of subjects treated with IMPOYZ Cream were application site atrophy, telangiectasia and rash.
