ADVERSE REACTIONS The most common adverse reaction occurring in ≥1% of subjects is nasopharyngitis. (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Acrotech Biopharma Inc. at 1-888-292-9617 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trial 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 safety of ADQUEY was assessed in two double-blind, vehicle-controlled clinical trials (Trial 2 and Trial 3) that enrolled 532 adult and pediatric subjects 2 years of age and older in Japan with mild to moderate atopic dermatitis (AD). Subjects applied ADQUEY or vehicle ointment topically twice daily for 4 weeks [ see Clinical Studies (14) ]. Adverse reactions reported by ≥1% of ADQUEY-treated subjects and more frequently than in subjects receiving vehicle are listed in Table 1. Table 1: Adverse Reactions Occurring in ≥1% of Adult and Pediatric Subjects 2 Years of Age and Older Treated with ADQUEY for Mild to Moderate Atopic Dermatitis (and Greater than Vehicle) through Week 4 in Trials 2 and 3 Adverse Reaction ADQUEY (N=267) n (%) Vehicle (N=265) n (%) Nasopharyngitis 16(6) 10(4) Less common (<1%) adverse reactions in subjects treated with ADQUEY in Trials 2 and 3 included application site folliculitis, contact dermatitis, application site rash, and molluscum contagiosum. In Trial 1, a vehicle-controlled dose ranging trial, 43 subjects 10 years of age and older in the United States, Australia, and Poland received ADQUEY topically twice daily for 8 weeks and the safety profile was consistent with Trials 2 and 3. In two additional vehicle-controlled dose ranging trials (Trial 4 and Trial 5), 92 subjects 2 years of age and older in Japan received ADQUEY topically twice daily for 4 weeks (Trial 4) and twice daily for 8 weeks (Trial 5) and the safety profile was consistent with Trials 2 and 3. In open-label trials of both Japanese and United States (US) subjects, 857 adult and pediatric subjects continued twice-daily treatment with ADQUEY for up to 52 weeks. The following application site adverse reactions occurred that led to drug discontinuation: pain, pruritus, vesicles, blistering, erythema, burning and contact dermatitis. 6.2 Postmarketing Experience The following adverse reactions have been identified during post approval use of ADQUEY. 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. General disorders and administration site condition : application site swelling.
