FULL PRESCRIBING INFORMATION: CONTENTS*
Clobetasol Propionate Emulsion Foam is indicated for the treatment of inflammatory and pruritic manifestations of corticosteroid-responsive dermatoses in patients 12 years and older.
Clobetasol Propionate Emulsion Foam is not for oral, ophthalmic, or intravaginal use.
Apply a thin layer of Clobetasol Propionate Emulsion Foam to the affected area(s) twice daily, morning and evening, for up to 2 consecutive weeks; therapy should be discontinued when control has been achieved. The maximum weekly dose should not exceed 50 g or an amount greater than 21 capfuls per week. For proper dispensing of foam, shake the can, hold it upside down, and depress the actuator. Dispense a small amount of foam (about a capful) and gently massage the medication into the affected areas (excluding the face, groin, and axillae) until the foam is absorbed. Avoid contact with the eyes.
Foam, 0.05%. Each gram of Clobetasol Propionate Emulsion Foam contains 0.5 mg of clobetasol propionate in a white to off-white petrolatum-based emulsion aerosol foam.
Clobetasol Propionate Emulsion Foam has been shown to suppress the hypothalamic-pituitary-adrenal (HPA) axis.
Systemic absorption of Clobetasol Propionate Emulsion has caused reversible HPA axis suppression with the potential for clinical glucocorticosteroid insufficiency. This may occur during treatment or upon withdrawal of the topical corticosteroid. Use of Clobetasol Propionate Emulsion Foam for longer than 2 weeks may suppress the immune system. [see Nonclinical Toxicology (13.1)].
In a trial including 37 subjects aged 12 and older with at least 30% body surface area (BSA), adrenal suppression was identified in 6 out of 37 subjects (16.2%) after 2 weeks of treatment with Clobetasol Propionate Emulsion. [see Clinical Pharmacology (12.2)].
Because of the potential for systemic absorption, use of Clobetasol Propionate Emulsion may require that patients be periodically evaluated for HPA axis suppression. Factors that predispose a patient using a topical corticosteroid to HPA axis suppression include the use of more potent steroids, use over large surface areas, use over prolonged periods, use under occlusion, use on an altered skin barrier, and use in patients with liver failure.
An adrenocorticotrophic hormone (ACTH) stimulation test may be helpful in evaluating patients for HPA axis suppression. If HPA axis suppression is documented, an attempt should be made to gradually withdraw the drug, to reduce the frequency of application, or to substitute a less potent steroid. Manifestations of adrenal insufficiency may require systemic corticosteroids. Recovery of HPA axis function is generally prompt and complete upon discontinuation of topical corticosteroids.
Cushing’s syndrome, hyperglycemia, and unmasking of latent diabetes mellitus can also result from systemic absorption of topical corticosteroids.
Use of more than 1 corticosteroid-containing product at the same time may increase the total systemic corticosteroid exposure.
Pediatric patients may be more susceptible to systemic toxicity from equivalent doses because of their larger skin surface- to-body mass ratios. [see Use in Specific Populations (8.4)].
Local adverse reactions may be more likely to occur with occlusive use, prolonged use, or use of higher potency corticosteroids. Reactions may include atrophy, striae, telangiectasias, burning, itching, irritation, dryness, folliculitis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection, and miliaria. Some local adverse reactions may be irreversible.
Allergic contact dermatitis to any component of topical corticosteroids is usually diagnosed by a failure to heal rather than a clinical exacerbation. Clinical diagnosis of allergic contact dermatitis can be confirmed by patch testing.
If irritation develops, treatment with Clobetasol Propionate Emulsion Foam should be discontinued and appropriate therapy instituted.
Concomitant skin infections should be treated with an appropriate antimicrobial agent. If the infection persists, Clobetasol Propionate Emulsion Foam should be discontinued until the infection has been adequately treated.
Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice.
In controlled clinical trials involving 821 subjects exposed to Clobetasol Propionate Emulsion Foam and vehicle foam, the pooled incidence of local adverse reactions in trials for atopic dermatitis and psoriasis with Clobetasol Propionate Emulsion Foam was 1.9% for application site atrophy and 1.6% for application site reaction. Most local adverse events were rated as mild to moderate and they were not affected by age, race, or gender.
The following additional local adverse reactions have been reported with topical corticosteroids: folliculitis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection, irritation, striae, and miliaria. They may occur more frequently with the use of occlusive dressings and higher potency corticosteroids, such as clobetasol propionate.
Cushing’s syndrome has been reported in infants and adults as a result of prolonged use of topical clobetasol propionate formulations.
Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
The following adverse reactions have been identified during post-approval use of clobetasol formulations: erythema, pruritus, burning, alopecia, and dryness.
Teratogenic Effects. Pregnancy Category C.
There are no adequate and well-controlled studies of Clobetasol Propionate Emulsion Foam in pregnant women. Clobetasol Propionate Emulsion Foam should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.
Corticosteroids have been shown to be teratogenic in laboratory animals when administered systemically at relatively low dosage levels. Some corticosteroids have been shown to be teratogenic after dermal application to laboratory animals.
Clobetasol propionate has not been tested for teratogenicity when applied topically; however, it is absorbed percutaneously, and when administered subcutaneously, it was a significant teratogen in both the rabbit and the mouse. Clobetasol propionate has greater teratogenic potential than steroids that are less potent.
Teratogenicity studies in mice using the subcutaneous route resulted in fetotoxicity at the highest dose tested (1 mg/kg) and teratogenicity at all dose levels tested down to 0.03 mg/kg. These doses are approximately 1.4 and 0.04 times, respectively, the human topical dose of Clobetasol Propionate Emulsion Foam based on body surface area comparisons. Abnormalities seen included cleft palate and skeletal abnormalities.
In rabbits, clobetasol propionate was teratogenic at doses of 0.003 and 0.01 mg/kg. These doses are approximately 0.02 and 0.05 times, respectively, the human topical dose of Clobetasol Propionate Emulsion Foam based on body surface area comparisons. Abnormalities seen included cleft palate, cranioschisis, and other skeletal abnormalities.
Systemically administered corticosteroids appear in human milk and could suppress growth, interfere with endogenous corticosteroid production, or cause other untoward effects. It is not known whether topical administration of corticosteroids could result in sufficient systemic absorption to produce detectable quantities in breast milk. Because many drugs are excreted in human milk, caution should be exercised when Clobetasol Propionate Emulsion Foam is administered to a nursing woman.
If used during lactation, Clobetasol Propionate Emulsion Foam should not be applied on the chest to avoid accidental ingestion by the infant.
Use in pediatric patients younger than 12 years is not recommended because of the risk of HPA axis suppression.
After 2 weeks of twice-daily treatment with Clobetasol Propionate Emulsion Foam, 7 of 15 subjects (47%) aged 6 to 11 years demonstrated HPA axis suppression. The laboratory suppression was transient; in all subjects serum cortisol levels returned to normal when tested 4 weeks post-treatment.
In 92 subjects aged from 12 to 17 years, safety was similar to that observed in the adult population. Based on these data, no adjustment of dosage of Clobetasol Propionate Emulsion Foam in adolescent patients aged 12 to 17 years is warranted. [see Warnings and Precautions (5.1)].
Because of a higher ratio of skin surface area to body mass, pediatric patients are at a greater risk than adults of HPA axis suppression and Cushing’s syndrome when they are treated with topical corticosteroids. They are therefore also at greater risk of adrenal insufficiency during and/or after withdrawal of treatment.
HPA axis suppression, Cushing’s syndrome, linear growth retardation, delayed weight gain, and intracranial hypertension have been reported in children receiving topical corticosteroids. Manifestations of adrenal suppression in children include low plasma cortisol levels and an absence of response to ACTH stimulation. Manifestations of intracranial hypertension include bulging fontanelles (in infants), headaches, and bilateral papilledema. Administration of topical corticosteroids to children should be limited to the least amount compatible with an effective therapeutic regimen. Chronic corticosteroid therapy may interfere with the growth and development of children.
Adverse effects, including striae, have been reported with inappropriate use of topical corticosteroids in infants and children.
A limited number of subjects aged 65 years or older have been treated with Clobetasol Propionate Emulsion Foam (n = 58) in US clinical trials. While the number of subjects is too small to permit separate analysis of efficacy and safety, the adverse reactions reported in this population were similar to those reported by younger subjects. Based on available data, no adjustment of dosage of Clobetasol Propionate Emulsion Foam in geriatric patients is warranted.
Topically applied Clobetasol Propionate Emulsion Foam can be absorbed in sufficient amounts to produce systemic effects.
Clobetasol Propionate Emulsion Foam, 0.05% is a white to off-white petrolatum-based emulsion aerosol foam containing the active ingredient clobetasol propionate USP, a synthetic corticosteroid for topical dermatologic use. Clobetasol, an analog of prednisolone, has a high degree of glucocorticoid activity and a slight degree of mineralocorticoid activity.
Clobetasol propionate is 21-chloro-9-fluoro-11ß,17-dihydroxy-16ß-methylpregna-1,4-diene-3,20-dione 17-propionate, with the empirical formula C25H32ClFO5, and a molecular weight of 466.97.
The following is the chemical structure:
Clobetasol propionate is a white to cream-colored crystalline powder, practically insoluble in water.
Each gram of Clobetasol Propionate Emulsion Foam contains 0.5 mg clobetasol propionate, USP. The foam also contains anhydrous citric acid, cetyl alcohol, cyclomethicone, isopropyl myristate, light mineral oil, polyoxyl 20 cetostearyl ether, potassium citrate monohydrate, propylene glycol, purified water, sorbitan monolaurate, white petrolatum, and phenoxyethanol as a preservative.
Clobetasol Propionate Emulsion Foam is dispensed from an aluminum can pressurized with a hydrocarbon (propane/butane) propellant.
Corticosteroids play a role in cellular signaling, immune function, inflammation, and protein regulation; however, the precise mechanism of action in corticosteroid-responsive dermatoses is unknown.
The contribution to efficacy by individual components of the vehicle has not been established.
In a trial evaluating the potential for HPA axis suppression using the cosyntropin stimulation test, Clobetasol Propionate Emulsion Foam demonstrated reversible adrenal suppression after 2 weeks of twice-daily use in subjects with atopic dermatitis of at least 30% body surface area (BSA). The proportion of subjects aged 12 years and older demonstrating HPA axis suppression was 16.2% (6 out of 37). In this trial HPA axis suppression was defined as serum cortisol level ≤18 mcg/dL 30 minutes post cosyntropin stimulation. The laboratory suppression was transient; in all subjects serum cortisol levels returned to normal when tested 4 weeks post treatment [see Warnings and Precautions (5.1), Use in Specific Populations (8.4)].
Topical corticosteroids can be absorbed from intact healthy skin. The extent of percutaneous absorption of topical corticosteroids is determined by many factors, including the product formulation and the integrity of the epidermal barrier. Occlusion, inflammation, and/or other disease processes in the skin may increase percutaneous absorption. The use of pharmacodynamic endpoints for assessing the systemic exposure of topical corticosteroids may be necessary due to the fact that circulating levels are often below the level of detection. Once absorbed through the skin, topical corticosteroids are metabolized primarily in the liver and are then excreted by the kidneys. Some corticosteroids and their metabolites are also excreted in the bile.
Following twice-daily application of Clobetasol Propionate Emulsion Foam for 1 week to 32 adult subjects with mild to moderate plaque-type psoriasis, mean peak plasma concentrations (±SD) of 59 ± 36 pg/mL of clobetasol were observed at around 5 hours post dose on Day 8.
Long-term animal studies have not been performed to evaluate the carcinogenic potential of Clobetasol Propionate Emulsion Foam or clobetasol propionate.
In a 90‑day repeat-dose toxicity study in rats, topical administration of Clobetasol Propionate Emulsion Foam at dose concentrations from 0.001% to 0.1% or from 0.03 to 0.3 mg/kg/day of clobetasol propionate resulted in a toxicity profile consistent with long-term exposure to corticosteroids including adrenal atrophy, histopathological changes in several organs systems indicative of severe immune suppression, and opportunistic fungal and bacterial infections. A no observable adverse effect level (NOAEL) could not be determined in this study. Although the clinical relevance of the findings in animals to humans is not clear, sustained glucocorticoid-related immune suppression may increase the risk of infection and possibly the risk for carcinogenesis.
Topical doses of 0% (foam vehicle), 0.001%, 0.01%, and 0.05% clobetasol propionate foam were evaluated in a 52-week dermal photocarcinogenicity study (40 weeks of treatment followed by 12 weeks of observation) conducted in hairless albino mice with concurrent exposure to low-level ultraviolet radiation. Topical treatment with increasing concentrations of clobetasol propionate foam did not have an adverse effect in this study. The results of this study suggest that topical treatment with Clobetasol Propionate Emulsion Foam would not enhance photocarcinogenesis.
Clobetasol propionate was non-mutagenic in 4 different test systems: the Ames test, the mouse lymphoma test, the Saccharomyces cerevisiae gene conversion assay, and the E. coli B WP2 fluctuation test. In the in vivo mouse micronucleus test, a positive finding was observed at 24 hours, but not at 48 hours, following oral administration at a dose of 2,000 mg/kg
Studies in the rat following subcutaneous administration of clobetasol propionate at dosage levels up to 0.05 mg/kg per day revealed that the females exhibited an increase in the number of resorbed embryos and a decrease in the number of living fetuses at the highest dose.
In a randomized trial of subjects 12 years and older with moderate to severe atopic dermatitis, 251 subjects were treated with Clobetasol Propionate Emulsion Foam and 126 subjects were treated with vehicle foam. Subjects were treated twice daily for 2 weeks. At the end of treatment, 131 of 251 subjects (52%) treated with Clobetasol Propionate Emulsion Foam compared with 18 of 126 subjects (14%) treated with vehicle foam achieved treatment success. Treatment success was defined by an Investigator’s Static Global Assessment (ISGA) score of clear (0) or almost clear (1) with at least 2 grades improvement from baseline, and scores of absent or minimal (0 or 1) for erythema and induration/papulation.
In an additional randomized trial of subjects 12 years and older with mild to moderate plaque-type psoriasis, 253 subjects were treated with Clobetasol Propionate Emulsion Foam and 123 subjects were treated with vehicle foam. Subjects were treated twice daily for 2 weeks. At the end of treatment, 41 of 253 subjects (16%) treated with Clobetasol Propionate Emulsion Foam compared with 5 of 123 subjects (4%) treated with vehicle foam achieved treatment success. Treatment success was defined by an ISGA score of clear (0) or almost clear (1) with at least 2 grades improvement from baseline, scores of none or faint/minimal (0 or 1) for erythema and scaling, and a score of none (0) for plaque thickness.
