11 DESCRIPTION WYNZORA (calcipotriene and betamethasone dipropionate) Cream contains anhydrous calcipotriene and betamethasone dipropionate intended for topical use. Calcipotriene is a synthetic vitamin D3 analog. Chemically, calcipotriene is (5Z,7E,22E,24S)-24-Cyclopropyl-9,10-secochola-5,7,10(19),22 tetraene-1α,3β,24-triol, with the empirical formula C 27 H 40 O 3 , a molecular weight of 412.6, and the following structural formula: Calcipotriene is a white or almost white powder. It is insoluble in water, freely soluble in ethanol and slightly soluble in methylene chloride. Betamethasone dipropionate is a synthetic corticosteroid. Betamethasone dipropionate has the chemical name Pregna-1,4-diene-3,20-dione,9-fluoro-11-hydroxy-16-methyl-17,21-bis(1-oxypropoxy)-,(11β,16β), with the empirical formula C 28 H 37 FO 7 , a molecular weight of 504.6, and the following structural formula: Betamethasone dipropionate is a white to almost white crystalline powder. It is practically insoluble in water, freely soluble in acetone and in methylene chloride, sparingly soluble in alcohol. Each gram of WYNZORA Cream contains 50 mcg of calcipotriene and 0.644 mg of betamethasone dipropionate (equivalent to 0.5 mg of betamethasone). WYNZORA Cream also contains the following inactive ingredients: isopropyl myristate, mineral oil, medium-chain triglycerides, isopropyl alcohol, polyoxyl lauryl ether, poloxamer (407), polyoxyl 40 hydrogenated castor oil, carbomer interpolymer (type A), butylated hydroxyanisole, trolamine, dibasic sodium phosphate, heptahydrate, monobasic sodium phosphate, monohydrate, alpha-tocopherol and purified water.

Side Effects (Adverse Reactions)
6 ADVERSE REACTIONS The most common adverse reactions reported by more than 1% of subjects treated with WYNZORA Cream were upper respiratory infection, headache, and application site irritation. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact MC2 Therapeutics Ltd at 1-800-644-8240 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 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. The rates of adverse reactions given below were reported in a randomized, multicenter, prospective, vehicle and active controlled clinical trial in adult subjects with plaque psoriasis. Subjects applied WYNZORA Cream, calcipotriene/betamethasone dipropionate topical suspension, 0.005%/0.064% or vehicle once daily for 8 weeks. The mean weekly dose of WYNZORA Cream was 33.8 g. A total of 342 subjects were treated with WYNZORA Cream, 337 with calcipotriene/betamethasone dipropionate topical suspension, 0.005%/0.064% and 115 with vehicle. The majority of subjects were White (87%) and male (62%). Approximately 72% were non-Hispanic/Latino. The mean age was 52 years and ages ranged from 18 to 89 years. The most common adverse reactions reported by ≥1% of subjects treated with WYNZORA Cream and more frequently than vehicle are presented in Table 1 below. Table 1: Adverse Reactions Through Week 8 Preferred Term WYNZORA Cream (N=342) Vehicle Cream (N=115) Upper Respiratory Infection (URI) Includes nasopharyngitis, upper respiratory tract infection (URTI), and viral URTI 7% 5% Headache 2% 0% Application site irritation 1% 0% 6.2 Postmarketing Experience The following adverse reactions have been identified during post-approval use of topical corticosteroids. 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. Postmarketing reports for local adverse reactions to topical corticosteroids included: atrophy, striae, telangiectasias, itching, dryness, hypopigmentation, perioral dermatitis, secondary infection, and miliaria. Ophthalmic adverse reactions of cataracts, glaucoma, and increased intraocular pressure, have been reported during use of topical corticosteroids, including topical betamethasone products.

Pregnancy and Breastfeeding
8.1 Pregnancy Risk Summary Available data with WYNZORA Cream are not sufficient to evaluate a drug-associated risk for major birth defects, miscarriages, or adverse maternal or fetal outcomes. Although there are no available data on use of the calcipotriene component in pregnant women, systemic exposure to calcipotriene after topical administration of WYNZORA Cream is likely to be low [see Clinical Pharmacology (12.3) ]. Observational studies suggest an increased risk of having low birthweight infants with the maternal use of potent or very potent topical corticosteroids (see Data ) . Advise pregnant women that WYNZORA Cream may increase the potential risk of having a low birth weight infant and to use WYNZORA Cream on the smallest area of skin and for the shortest duration possible. In animal reproduction studies, oral administration of calcipotriene to pregnant rats during the period of organogenesis resulted in an increased incidence of minor skeletal abnormalities, including enlarged fontanelles and extra ribs (see Data ) . Oral administration of calcipotriene to pregnant rabbits during the period of organogenesis had no apparent effects on embryo-fetal development. Subcutaneous administration of betamethasone dipropionate to pregnant rats and rabbits during the period of organogenesis resulted in fetal toxicity, including fetal deaths, reduced fetal weight, and fetal malformations (cleft palate and crooked or short tail) (see Data ) . The available data do not allow the calculation of relevant comparisons between the systemic exposures of calcipotriene and betamethasone dipropionate observed in animal studies to the systemic exposures that would be expected in humans after topical use of WYNZORA Cream. The background risk of major birth defects and miscarriage in the indicated population is unknown. All pregnancies have a background risk of birth defect, loss, or other adverse outcomes. In the U.S. general population, the estimated background risk of major...
