Clinical Trials Conducted in Subjects 18 years and older with Psoriasis of the Scalp The rates of adverse reactions described below were from randomized, multicenter, vehicle- and/or active controlled clinical trials in adult subjects with psoriasis of the scalp [see Clinical Studies (14) ]. Subjects applied study product once daily for 8 weeks, and the median weekly dose was 12.6 grams. Adverse reactions that occurred in ≥ 1% of subjects treated with Taclonex Topical Suspension and at a rate higher than in subjects treated with vehicle are presented in Table 1. Table 1. Number and Percentage of Subjects with Adverse Reactions in Scalp Psoriasis Trials (Events Reported by ≥1% of Subjects and for Which a Relationship is Possible) Taclonex Topical Suspension Betamethasone Dipropionate in vehicle Calcipotriene in vehicle Vehicle N=1,953 N=1,214 N=979 N=173 Event # of subjects (%) Folliculitis 16 (1%) 12 (1%) 5 (1%) 0 (0%) Burning sensation of skin 13 (1%) 10 (1%) 29 (3%) 0 (0%) Other less common adverse reactions (<1% but >0.1%) were, in decreasing order of incidence: acne, exacerbation of psoriasis, eye irritation, and pustular rash. In a 52-week trial, adverse reactions that were reported by >1% of subjects treated with Taclonex Topical Suspension were pruritus (3.6%), psoriasis (2.4%), erythema (2.1%), skin irritation (1.4%), and folliculitis (1.2%). Clinical Trials Conducted in Subjects 18 years and older with Psoriasis of the Body In randomized, multicenter, vehicle- and/or active controlled clinical trials in adult subjects with plaque psoriasis on non-scalp areas, 824 subjects applied Taclonex Topical Suspension once daily for 8 weeks [see Clinical Studies (14) ]. The median weekly dose was 22.6 grams. There were no adverse reactions that occurred in ≥1% of subjects treated with Taclonex Topical Suspension and at a rate higher than in subjects treated with vehicle. Other less common adverse reactions (<1% but >0.1%) were, in decreasing order of incidence: rash and folliculitis. Clinical Trials Conducted in Subjects 12 to 17 years with Psoriasis of the Scalp In two uncontrolled clinical trials, 109 subjects aged 12 to 17 years with plaque psoriasis of the scalp applied Taclonex ® Topical Suspension once daily for up to 8 weeks. The median weekly dose was 40 grams. Adverse reactions included acne, acneiform dermatitis and application site pruritus (0.9% each) [see Use in Specific Populations (8.4) and Clinical Pharmacology (12.2) ] . Clinical Trial Conducted in Subjects 12 to 17 years with Psoriasis of the Scalp and Body In an uncontrolled clinical trial, 107 subjects aged 12 to 17 years with plaque psoriasis of the scalp and body applied Taclonex Topical Suspension once daily for up to 8 weeks. The median weekly dose was 26.6 grams. Adverse reactions were folliculitis, acne, and erythema (0.9% each) [see Use in Specific Populations (8.4) and Clinical Pharmacology (12.2) ] . 6.2 Postmarketing Experience Because adverse 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, increased intraocular pressure, and central serous chorioretinopathy have been reported during use of topical corticosteroids, including topical betamethasone products.
