Description

11 DESCRIPTION EUCRISA contains 2% crisaborole (w/w) in a petrolatum-based, white to off-white ointment and is for topical use. The active ingredient, crisaborole, is a phosphodiesterase-4 (PDE-4) inhibitor. Crisaborole is described chemically as 5-(4-cyanophenoxy)-1,3-dihydro-1-hydroxy-[2,1]-benzoxaborole. The empirical formula is C 14 H 10 BNO 3 and the molecular weight is 251.1 g/mol. The structural formula is represented below: Crisaborole drug substance is freely soluble in common organic solvents such as isopropyl alcohol and propylene glycol, and insoluble in water. Each gram of EUCRISA contains 20 mg of crisaborole in an ointment containing white petrolatum, propylene glycol, mono- and di-glycerides, paraffin, butylated hydroxytoluene, and edetate calcium disodium.

What Is Crisaborole Used For?

1 INDICATIONS AND USAGE EUCRISA is indicated for topical treatment of mild to moderate atopic dermatitis in adult and pediatric patients 3 months of age and older. EUCRISA is a phosphodiesterase 4 inhibitor indicated for topical treatment of mild to moderate atopic dermatitis in adult and pediatric patients 3 months of age and older. ( 1 )

  • Side Effects (Adverse Reactions)

    6 ADVERSE REACTIONS The most common adverse reaction occurring in ≥1% in subjects is application site pain. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact Pfizer Inc. at 1-800-438-1985 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. In two double-blind, vehicle-controlled clinical trials (Trial 1 and Trial 2), 1012 subjects 2 to 79 years of age with mild to moderate atopic dermatitis were treated with EUCRISA twice daily for 4 weeks. The adverse reaction reported by ≥1% of EUCRISA-treated subjects is listed in Table 1. Table 1: Adverse Reaction Occurring in ≥1% of Subjects in Atopic Dermatitis Trials through Week 4 Adverse Reaction EUCRISA Twice Daily N=1012 n (%) Vehicle Twice Daily N=499 n (%) Application site pain Refers to skin sensations such as burning or stinging. 45 (4) 6 (1) Less common (<1%) adverse reactions in subjects treated with EUCRISA included contact urticaria [see Warnings and Precautions (5.1) ]. In one double-blind, vehicle-controlled trial including an initial open-label period (Trial 3), 497 subjects 3 months of age and older with mild to moderate atopic dermatitis received EUCRISA twice daily for up to 8 weeks. This was followed by a double-blind period, during which 135 subjects out of 270 randomized subjects received EUCRISA and 135 subjects received vehicle once daily for 52 weeks or until they developed a flare. The adverse reactions observed in the open-label period were similar to the known safety profile of twice daily treatment with EUCRISA. The adverse reactions observed with once daily treatment were similar to vehicle [see Clinical Studies (14) ] . 6.2 Postmarketing Experience The following adverse reactions have been identified during postapproval use of EUCRISA. 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: allergic contact dermatitis

    Contraindications

    4 CONTRAINDICATIONS EUCRISA is contraindicated in patients with known hypersensitivity to crisaborole or any component of the formulation. [see Warnings and Precautions (5.1) ] Known hypersensitivity to crisaborole or any component of the formulation. ( 4 )

    Pregnancy and Breastfeeding

    8.1 Pregnancy Risk Summary Available data from case reports with EUCRISA use in pregnant women are insufficient to inform a drug-associated risk for major birth defects, miscarriage, or other adverse maternal or fetal outcomes. In animal reproduction studies, there were no adverse developmental effects observed with oral administration of crisaborole in pregnant rats and rabbits during organogenesis at doses up to 3 and 2 times, respectively, the maximum recommended human dose (MRHD) ( see Data ). The background risk of major birth defects and miscarriage for the indicated population is unknown. All pregnancies carry some risk of birth defect, loss, or other adverse outcomes. The background risk of major birth defects in the U.S. general population is 2% to 4% and of miscarriage is 15% to 20% of clinically recognized pregnancies. Data Animal Data Rat and rabbit embryo-fetal development was assessed after oral administration of crisaborole. Crisaborole did not cause adverse effects to the fetus at oral doses up to 300 mg/kg/day in pregnant rats during the period of organogenesis (3 times the MRHD on an area under the curve (AUC) comparison basis). No crisaborole-related fetal malformations were noted after oral treatment with crisaborole in pregnant rats at doses up to 600 mg/kg/day (13 times the MRHD on an AUC comparison basis) during the period of organogenesis. Maternal toxicity was produced at this high dose of 600 mg/kg/day in pregnant rats and was associated with decreased fetal body weight and delayed skeletal ossification. Crisaborole did not cause adverse effects to the fetus at oral doses up to the highest dose tested of 100 mg/kg/day in pregnant rabbits during the period of organogenesis (2 times the MRHD on an AUC comparison basis). In a prenatal/postnatal development study, pregnant rats were treated with crisaborole at doses of 150, 300, or 600 mg/kg/day by oral gavage during gestation and lactation (from gestation day 7 through day 20 of lactation)....
