LEXETTE

1 INDICATIONS AND USAGE LEXETTE ® is indicated for the topical treatment of plaque psoriasis in patients 12 years of age and older. LEXETTE is a corticosteroid indicated for the topical treatment of plaque psoriasis in patients twelve (12) years of age and older. ( 1 )

2 DOSAGE AND ADMINISTRATION Shake can prior to use and turn can completely upside down to dispense. Apply LEXETTE 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. LEXETTE is for topical use only. LEXETTE is not for ophthalmic, oral, or intravaginal use. • Shake before use.

4 CONTRAINDICATIONS None. None.

5 WARNINGS AND PRECAUTIONS • Reversible hypothalamic-pituitary-adrenal (HPA) axis suppression may occur, with the potential for glucocorticosteroid insufficiency during or after treatment. ( 5.1 ) • Systemic effects following prolonged exposure of topical corticosteroids may also include Cushing’s syndrome, hyperglycemia, and glucosuria. ( 5.1 ) • Use of potent corticosteroids on large areas, for prolonged durations, under occlusive dressings, or on an altered skin barrier may increase systemic exposure. ( 5.1 ) • Children may be more susceptible to systemic toxicity when treated with topical corticosteroids. ( 5.1 , 8.4 ) • Local adverse reactions with topical steroids may include atrophy, striae, irritation, acneiform eruptions, hypopigmentation, and allergic contact dermatitis. Adverse reactions may be more likely to occur with occlusive use or more potent corticosteroids. ( 5.2 ) • Topical corticosteroids may increase the risk of cataract and glaucoma formation. If visual symptoms occur, consider referral to an ophthalmologist for evaluation. ( 5.3 ) • Initiate appropriate therapy if concomitant skin infections develop. ( 5.4 ) • Flammable contents. Avoid heat, flame, or smoking during and immediately following application. ( 5.6 ) 5.1 Hypothalamic-Pituitary-Adrenal (HPA) Axis Suppression and Other Adverse Endocrine Effects LEXETTE 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 LEXETTE was evaluated in the following studies: • In a study of 25 adult subjects with moderate to severe plaque psoriasis involving ≥15% of their body surface area. LEXETTE 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. All subjects returned to normal HPA axis function at follow-up at least 4 weeks after stopping the treatment [see Clinical Pharmacology ( 12.2 )] . • In another clinical study, 24 subjects 12 to less than 18 years old with stable plaque psoriasis involving 10% or more of their body surface area applied LEXETTE to affected areas twice daily for two weeks. Of the 23 subjects evaluated for HPA axis suppression, laboratory evidence of adrenal suppression occurred in 6 subjects (26.1%), whom recovered upon retesting after at least 4 weeks of stopping the treatment [see Clinical Pharmacology ( 12.2 )] . Because of the potential for systemic absorption, use of topical corticosteroids, including LEXETTE, 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 )] . 5.2 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 LEXETTE. Some local adverse reactions may be irreversible. 5.3 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. Advise patients to report any visual symptoms and consider referral to an ophthalmologist for evaluation. 5.4 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 LEXETTE until the infection has been adequately treated. 5.5 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 LEXETTE if allergic contact dermatitis is established. 5.6 Flammability LEXETTE is flammable. Avoid fire, flame, or smoking during and immediately following application.

6 ADVERSE REACTIONS 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 )] The most commonly reported adverse reactions (≥1%) are application site pain and headache.

In randomized, multicenter, vehicle-controlled clinical trials, 351 adults with plaque psoriasis were treated with LEXETTE 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. Table 1: Adverse Reactions Occurring in ≥ 1% of Subjects through Week 2 HBP Foam N=351 Vehicle Foam N=353 Adverse Reaction % % Application site burning/stinging 12% 15% Application site pain 1% <1% Headache 1% <1% Skin atrophy (n=1) and telangiectasia (n=2) were reported with LEXETTE, but not with vehicle foam. 6.2 Postmarketing Experience Because the 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 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 halobetasol propionate.

8.1 Pregnancy Risk Summary There are no available data on LEXETTE 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 LEXETTE [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. Data Animal Data 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.
