CALCIPOTRIENE

Calcipotriene foam contains the compound calcipotriene, a synthetic vitamin D3 analog, in an aqueous-based emulsion foam vehicle for topical dermatologic use. Chemically, calcipotriene is (5Z,7E,22E,24S)-24-cyclopropyl-9,10-secochola-5,7,10(19), 22-tetraene- 1α,3β,24-triol. The structural formula is represented below: Molecular Formula: C27H40O3 Molecular Weight: 412.6 Calcipotriene is a white or off-white crystalline substance. Calcipotriene foam contains calcipotriene 50 mcg/g in an aqueous-based emulsion foam vehicle consisting of cetyl alcohol, dibasic sodium phosphate, dl-α-tocopherol, edetate disodium, isopropyl myristate, light mineral oil, polyoxyl 20 cetostearyl ether, propylene glycol, purified water, stearyl alcohol, and white petrolatum. Calcipotriene foam is dispensed from an aluminum can pressurized with a hydrocarbon (propane/n-butane/isobutane) propellant. Chemical Structure

Calcipotriene foam is indicated for the topical treatment of plaque psoriasis of the scalp and body in adults and pediatric patients 4 years of age and older. Calcipotriene foam, is a vitamin D analog indicated for the topical treatment of plaque psoriasis of the scalp and body in adults and pediatric patients 4 years of age and older. ( 1 )

Calcipotriene foam is for topical use only. Calcipotriene foam is not for oral, ophthalmic, or intravaginal use. Apply a thin layer of calcipotriene foam twice daily to the affected areas and rub in gently and completely. Avoid contact with the face and eyes. For topical use only; not for oral, ophthalmic, or intravaginal use. ( 2 ) Apply twice daily. ( 2 )

Calcipotriene foam should not be used by patients with known hypercalcemia. Do not use in patients with known hypercalcemia. ( 4 )

Adverse reactions reported in ≥ 1% of subjects treated with Calcipotriene foam and at a higher incidence than subjects treated with vehicle were application site erythema and application site pain.

( 6 ) 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in clinical trials of a drug cannot be directly compared with rates in the clinical trials of another drug and may not reflect the rates observed in clinical practice. Calcipotriene foam was studied in four vehicle-controlled trials. A total of 1094 adult subjects with plaque psoriasis, including 654 exposed to calcipotriene foam, were treated twice daily for 8 weeks. Adverse reactions reported in ≥1% of subjects treated with calcipotriene foam and at a higher incidence than subjects treated with vehicle were application site erythema (2%) and application site pain (3%). The incidence of these adverse reactions was similar between the body and scalp. In an open-label study, 19 pediatric subjects age 12 to less than 17 years applied calcipotriene foam twice daily for 14 days and once on Day 15. Adverse reactions included application site pain, application site pruritus and pruritus [see Clinical Pharmacology (12.2 and 12.3) and Pediatric Use (8.4) ] . In an open-label study, 36 pediatric subjects age 4 to less than 12 years applied calcipotriene foam twice daily for up to 8 weeks. Adverse reactions included application site pain and contact dermatitis [see Clinical Pharmacology (12.2 and 12.3) and Pediatric Use (8.4) ] . 6.2 Postmarketing Experience The following adverse reactions have been identified during post approval use of calcipotriene foam. 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. Skin and Subcutaneous: application site vesicles
