Indications and Usage for Halobetasol Foam
Halobetasol Propionate Topical Foam is indicated for the topical treatment of plaque psoriasis in patients 18 years of age and older.
Halobetasol Foam Dosage and Administration
Shake can prior to use. Apply Halobetasol Propionate Topical Foam as a thin uniform film to the affected skin twice daily for up to two weeks. Rub in gently. Wash hands after applying the product.
Discontinue therapy when control is achieved. If no improvement is seen within two weeks, reassessment of the diagnosis may be necessary.
Treatment beyond two weeks is not recommended and the total dosage should not exceed 50 grams per week because of the potential for the drug to suppress the hypothalamic-pituitary adrenal (HPA) axis [see Warnings and Precautions (5.1)]. Do not use with occlusive dressings unless directed by a physician.
Avoid use on the face, groin, or axillae.
Avoid contact with eyes. Wash hands after each application, unless it is for treatment of the hands.
Halobetasol Propionate Topical Foam is for topical use only.
Halobetasol Propionate Topical Foam is not for ophthalmic, oral, or intravaginal use.
Dosage Forms and Strengths
Halobetasol Propionate Topical Foam is a white to off-white topical foam. Each gram of Halobetasol Propionate Topical Foam, 0.05% contains 0.5 mg of halobetasol propionate.
Warnings and Precautions
Hypothalamic-Pituitary-Adrenal (HPA) Axis Suppression and Other Adverse Endocrine Effects
Halobetasol Propionate Topical Foam is a topical corticosteroid that has been shown to suppress the hypothalamic-pituitary-adrenal (HPA) axis.
Systemic effects of topical corticosteroids may include reversible HPA axis suppression, with the potential for glucocorticosteroid insufficiency. This may occur during treatment or upon withdrawal of treatment of the topical corticosteroid. The potential for hypothalamic-pituitary adrenal (HPA) suppression with Halobetasol Propionate Topical Foam was evaluated in a study of 25 adult subjects with moderate to severe plaque psoriasis involving ≥15% of their body surface area. Halobetasol Propionate Topical Foam produced laboratory evidence of HPA axis suppression when used twice daily for two weeks in 6 out of 25 (24%) adult subjects with plaque psoriasis. Recovery of HPA axis function was generally prompt with the discontinuation of treatment [see Clinical Pharmacology (12.2)].
Because of the potential for systemic absorption, use of topical corticosteroids, including Halobetasol Propionate Topical Foam, may require that patients be evaluated periodically for evidence of HPA axis suppression. Factors that predispose a patient using a topical corticosteroid to HPA axis suppression include the use of more potent corticosteroids, use over large surface areas, prolonged use, occlusive use, use on an altered skin barrier, concomitant use of multiple corticosteroid-containing products, liver failure, and young age. An ACTH stimulation test may be helpful in evaluating patients for HPA axis suppression.
If HPA axis suppression is documented, attempt to gradually withdraw the drug, reduce the frequency of application, or substitute a less potent steroid. Manifestations of adrenal insufficiency may require supplemental systemic corticosteroids. Recovery of HPA axis function is generally prompt and complete upon discontinuation of topical corticosteroids.
Systemic effects of topical corticosteroids may also include Cushing's syndrome, hyperglycemia, and glucosuria. Use of more than one corticosteroid-containing product at the same time may increase the total systemic exposure to topical corticosteroids.
Pediatric patients may be more susceptible than adults to systemic toxicity from the use of topical corticosteroids due to their larger surface-to-body mass ratios [see Use in Specific Populations (8.4)].
Local Adverse Reactions
Local adverse reactions from topical corticosteroids may include atrophy, striae, telangiectasias, burning, itching, irritation, dryness, folliculitis, acneiform eruptions, hypopigmentation, perioral dermatitis, allergic contact dermatitis, secondary infection, and miliaria. These may be more likely to occur with occlusive use, prolonged use, or use of higher potency corticosteroids, including Halobetasol Propionate Topical Foam. Some local adverse reactions may be irreversible.
Ophthalmic Adverse Reactions
Use of topical corticosteroids may increase the risk of posterior subcapsular cataracts and glaucoma. Cataracts and glaucoma have been reported in postmarketing experience with the use of topical corticosteroid products.
Concomitant Skin Infections
Use an appropriate antimicrobial agent if a skin infection is present or develops. If a favorable response does not occur promptly, discontinue use of Halobetasol Propionate Topical Foam until the infection has been adequately treated.
Allergic Contact Dermatitis
Allergic contact dermatitis with corticosteroids is usually diagnosed by observing failure to heal rather than noting a clinical exacerbation. Consider confirmation of a clinical diagnosis of allergic contact dermatitis by appropriate patch testing. Discontinue Halobetasol Propionate Topical Foam if allergic contact dermatitis is established.
Halobetasol Propionate Topical Foam is flammable. Avoid fire, flame, or smoking during and immediately following application.
The following adverse reactions are discussed in greater detail in other sections of the label:
- Hypothalamic-Pituitary-Adrenal (HPA) Axis Suppression and Other Adverse Endocrine Effects [see Warnings and Precautions (5.1)]
- Allergic Contact Dermatitis [see Warnings and Precautions (5.5)]
Clinical Trials Experience
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 practice.
In randomized, multicenter, vehicle-controlled clinical trials, 351 adults with plaque psoriasis were treated with Halobetasol Propionate Topical Foam twice daily for up to two weeks (up to approximately 50 grams per week). Table 1 presents selected adverse reactions that occurred in at least 1% of subjects.

USE IN SPECIFIC POPULATIONS
There are no available data on Halobetasol Propionate Topical Foam use in pregnant women to inform a drug-associated risk for adverse developmental outcomes. In animal reproduction studies, increased malformations, including cleft palate and omphalocele, were observed after oral administration of halobetasol propionate during organogenesis to pregnant rats and rabbits. No comparisons of animal exposure with human exposure may be calculated due to minimal systemic exposure in humans after topical administration of Halobetasol Propionate Topical Foam [see Clinical Pharmacology (12.3)] .
The background risk of major birth defects and miscarriage for the indicated population are unknown. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.
Halobetasol propionate has been shown to cause malformations in rats and rabbits when given orally during organogenesis at doses of 0.04 to 0.1 mg/kg/day in rats and 0.01 mg/kg/day in rabbits. Halobetasol propionate was embryotoxic in rabbits, but not in rats. Cleft palate was observed in both rats and rabbits. Omphalocele was seen in rats, but not in rabbits.
There are no data on the presence of halobetasol propionate or its metabolites in human milk, the effects on the breastfed infant, or the effects on milk production after topical application to women who are breastfeeding.
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 human milk. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for Halobetasol Propionate Topical Foam and any potential adverse effects on the breastfed infant from Halobetasol Propionate Topical Foam or from the underlying maternal condition.
Advise breastfeeding women not to apply Halobetasol Propionate Topical Foam directly to the nipple and/or areola to avoid direct infant exposure.
Safety and effectiveness of Halobetasol Propionate Topical Foam in patients younger than 18 years of age have not been established.
Because of higher skin surface area to body mass ratios, 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 or after withdrawal of treatment. Adverse reactions including striae have been reported with use of topical corticosteroids in infants and children [see Warnings and Precautions (5.1)].
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, headaches, and bilateral papilledema [see Warnings and Precautions (5.1)].
Clinical studies with Halobetasol Propionate Topical Foam included 131 patients aged 65 years and over. No overall differences in safety or effectiveness were observed between these patients and those younger than 65 years.
Topically applied Halobetasol Propionate Topical Foam can be absorbed in sufficient amounts to produce systemic effects [see Warnings and Precautions (5.1)].
Halobetasol Foam Description
Halobetasol Propionate Topical Foam is a hydroethanolic aerosol foam that contains a corticosteroid, halobetasol propionate. The chemical name of halobetasol propionate is 21 chloro-6α, 9-difluoro-11β, 17-dihydroxy-16β-methylpregna-1, 4-diene-3,20-dione 17 propionate. Halobetasol propionate is a white to off-white crystalline powder with a molecular weight of 484.96 and a molecular formula of C 25H 31ClF 2O 5. It has the following structural formula:
It is practically insoluble in water and freely soluble in dichloromethane and in acetone. Each gram of Halobetasol Propionate Topical Foam contains 0.5 mg of halobetasol propionate in a white to off-white foam base consisting of alcohol (specially denatured alcohol [SDA]), benzoic acid, cetostearyl alcohol, emulsifying wax, polyoxyl 20 cetostearyl ether, propylene glycol and purified water. Halobetasol Propionate Topical Foam is dispensed from an aluminum can pressurized with a hydrocarbon (isobutane and propane) propellant.
Halobetasol Foam - Clinical Pharmacology
Mechanism of Action
Corticosteroids play a role in cellular signaling, immune function, inflammation, and protein regulation; however, the precise mechanism of action in plaque psoriasis is unknown.
The potential for hypothalamic-pituitary adrenal (HPA) suppression was evaluated in a study of 25 adult subjects with moderate to severe plaque psoriasis involving a mean body surface area of 18.4%. A mean dose of 3.7 g Halobetasol Propionate Topical Foam was applied twice daily for two weeks and produced laboratory evidence of HPA axis suppression in 6 of 25 (24%) subjects. In this study, the criteria for HPA-axis suppression was a serum cortisol level of less than or equal to 18 micrograms per deciliter 30 minutes after stimulation with cosyntropin (adrenocorticotropic hormone). These effects were reversible as recovery of HPA axis function was generally prompt with the discontinuation of treatment [see Warnings and Precautions (5.1)].
The extent of percutaneous absorption of topical corticosteroids is determined by many factors, including the vehicle, the integrity of the epidermal barrier, and the use of occlusive dressings. Topical corticosteroids can be absorbed from normal intact skin. Inflammation and/or other disease processes in the skin may increase percutaneous absorption.
In the HPA-axis and pharmacokinetic study, as described above in Clinical Pharmacology (12.2), pharmacokinetics was evaluated in a subgroup of 23 adult subjects with moderate to severe plaque psoriasis following twice daily treatment for 14 days with a mean daily dose of 7.4 g. Plasma concentration of halobetasol propionate was measureable in all subjects and steady state was achieved by Day 14. The mean (± standard deviation) C max concentration for Halobetasol Propionate Topical Foam on Day 14 was 199.7 ± 217.3 pg/mL, with the corresponding median T max value of 1 hour (range 0 – 12 hours); mean area under the halobetasol propionate concentration versus time curve over the dosing interval (AUC t) was 1434.9 ± 1310.6 pg∙h/mL.
Carcinogenesis, Mutagenesis, Impairment of Fertility
Long-term animal studies have not been performed to evaluate the carcinogenic potential of halobetasol propionate.
In a 90-day repeat-dose toxicity study in rats, topical administration of Halobetasol Propionate Topical Foam at dose concentrations from 0.005% to 0.05% or from 0.011 to 0.11 mg/kg/day of halobetasol propionate resulted in a toxicity profile consistent with long-term exposure to corticosteroids including adrenal atrophy, histopathological changes in several organ systems indicative of severe immune suppression, and opportunistic fungal and bacterial infections. A noobservable adverse effect level 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 of carcinogenesis.
Halobetasol propionate was not found to be genotoxic in the Ames/Salmonella assay, in the Chinese hamster CHO/HGPRT assay, in the mouse micronucleus test, in the sister chromatid exchange test in somatic cells of the Chinese hamster, or in the chromosome aberration test in somatic cells of Chinese hamsters. Positive mutagenicity effects were observed in two genotoxicity assays: Chinese hamster nuclear anomaly test and mouse lymphoma gene mutation assay in vitro.
Studies in the rat following oral administration at dose levels up to 0.05 mg/kg/day indicated no impairment of fertility or general reproductive performance.
Halobetasol Propionate Topical Foam was evaluated for the treatment of moderate to severe plaque psoriasis in two multicenter, randomized, double-blind, vehicle-controlled studies (Study 1 [NCT02368210] and Study 2 [NCT02742441]).
These studies were conducted in 560 subjects 18 years of age and older with plaque psoriasis involving between 2% and 12% body surface area. Baseline disease severity was determined using a static, five-level Investigator's Global Assessment (IGA) scale, on which a subject scored either moderate or severe. Overall, approximately 60% of subjects were male and approximately 90% were Caucasian.
Subjects applied Halobetasol Propionate Topical Foam or vehicle to all affected areas twice daily for up to 14 consecutive days.
The primary measure of efficacy was Overall Treatment Success, defined as the proportion of subjects who were cleared or almost cleared with at least a two-grade improvement from baseline at Week 2 (end of treatment) based on the IGA. The studies also evaluated treatment success for the individual signs of psoriasis (plaque elevation, scaling, and erythema) at the end of treatment. Table 2 presents these results.
|Study 1||Study 2|
|Overall Treatment Success *||19 (25%)||3 (4%)||63 (31%)||15 (7%)|
|Plaque Elevation †||20/75 (27%)||3/76 (4%)||71/202 (35%)||20/203 (10%)|
|Scaling †||21/75 (28%)||4/76 (5%)||68/201 (34%)||20/204 (10%)|
|Erythema †||16/75 (21%)||2/76 (3%)||59/205 (29%)||17/204 (8%)|
