  • 1 INDICATIONS AND USAGE

    EXTINA (ketoconazole) Foam, 2% is indicated for the topical treatment of seborrheic dermatitis in immunocompetent patients 12 years of age and older.

    Limitations of Use
    Safety and efficacy of EXTINA Foam for treatment of fungal infections have not been established.

  • 2 DOSAGE AND ADMINISTRATION

    EXTINA Foam should be applied to the affected area(s) twice daily for four weeks.

    Hold the container upright, and dispense EXTINA Foam into the cap of the can or other cool surface in an amount sufficient to cover the affected area(s). Dispensing directly onto hands is not recommended, as the foam will begin to melt immediately upon contact with warm skin. Pick up small amounts of EXTINA Foam with the fingertips, and gently massage into the affected area(s) until the foam disappears. For hair-bearing areas, part the hair, so that EXTINA Foam may be applied directly to the skin (rather than on the hair).

    Avoid contact with the eyes and other mucous membranes. EXTINA Foam is not for ophthalmic, oral or intravaginal use.

  • 3 DOSAGE FORMS AND STRENGTHS

    EXTINA (ketoconazole) Foam, 2% contains 20 mg of ketoconazole, USP per gram, supplied in 50 g and 100 g containers.

  • 4 CONTRAINDICATIONS

    None. 

  • 5 WARNINGS AND PRECAUTIONS

    5.1 Contact Sensitization

    EXTINA Foam may result in contact sensitization, including photoallergenicity [see Adverse Reactions (6.2)].

    5.2 Flammable Contents

    The contents of EXTINA Foam include alcohol and propane/butane, which are flammable. Avoid fire, flame and/or smoking during and immediately following application. Do not puncture and/or incinerate the containers. Do not expose containers to heat and/or store at temperatures above 120°F (49°C).

    5.3 Systemic Effects

    Hepatitis has been seen with orally administered ketoconazole (1:10,000 reported incidence). Lowered testosterone and ACTH–induced corticosteroid serum levels have been seen with high doses of orally administered ketoconazole. These effects have not been seen with topical ketoconazole.

  • 6 ADVERSE REACTIONS

    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 adverse reaction information from clinical trials does, however, provide a basis for identifying the adverse reactions that appear to be related to drug use and for approximating rates.

    The safety data presented in Table 1 reflect exposure to EXTINA Foam in 672 subjects, 12 years and older with seborrheic dermatitis. Subjects applied EXTINA Foam or vehicle foam twice daily for 4 weeks to affected areas on the face, scalp, and/or chest. Adverse reactions occurring in > 1% of subjects are presented in Table 1.

    6.2 Dermal Safety Studies

    In a photoallergenicity study, 9 of 53 subjects (17%) had reactions during the challenge period at both the irradiated and non-irradiated sites treated with EXTINA Foam. EXTINA Foam may cause contact sensitization.

    6.3 Postmarketing Experience

    The following adverse events have been identified during postmarketing use of EXTINA Foam:

    Gastrointestinal disorders: Cheilitis
    General disorders and administration site conditions:  Application site pain and application site burn
    Skin and subcutaneous tissue disorders: Skin burning sensation and erythema

    Because these events 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.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    There are no available data on EXTINA Foam use in pregnant women to identify a drug‑associated risk of major birth defects, miscarriage or adverse maternal or fetal outcomes. No reproductive studies in animals have been performed with EXTINA Foam. In animal reproduction studies with pregnant mice, rats and rabbits both embryotoxic and developmental effects (structural abnormalities) were observed following oral dosing of ketoconazole during organogenesis. Assuming equivalent systemic absorption of topical and oral ketoconazole doses and an EXTINA Foam maximum recommended human dose (MRHD) of 8 grams (equivalent to 160 mg ketoconazole), embryotoxic effects were observed at 0.8 to 2.4 times the MRHD and developmental effects were observed at 4.8 times the MRHD [see Data].

    The background risk of major birth defects and miscarriage for 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 birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively.

    Data

    Animal Data

    The animal multiples of human exposure calculations are based on body surface area (BSA) comparisons of oral doses administered to animals and an EXTINA Foam maximum recommended human dose (MRHD) of 8 grams (equivalent to 2.67 mg ketoconazole/kg/day for a 60 kg individual or 98.8 mg ketoconazole/m2/day).

    Embryofetal development studies have been conducted in mice, rats and rabbits with orally administered ketoconazole. When orally administered to mice on gestational days 6 through 18 (covering the period of organogenesis), ketoconazole was embryotoxic (25 mg/kg and higher; 0.8 times the MRHD based on BSA comparisons) with a high incidence of resorptions, increased number of stillbirths and delayed parturition. Delays in maturation were also observed. There was no evidence of maternal toxicity or malformations at up to 50 mg/kg (1.5 times the MRHD based on BSA comparisons). No treatment related developmental effects were observed at 10 mg/kg (0.3 times the MRHD based on BSA comparisons).

    In the presence of maternal toxicity in rats, orally administered ketoconazole was both embryotoxic (40 mg/kg and higher; 2.4 times the MRHD based on BSA comparisons), including increased resorbed fetuses and stillbirths, and teratogenic (80 mg/kg and higher; 4.8 times the MRHD based on BSA comparisons), including syndactylia, oligodactylia, waved ribs and cleft palate. Additionally, 100 mg/kg (6 times the MRHD based on BSA comparisons) ketoconazole orally administered on a single day during gestation (gestational days 9 through 12) was embryotoxic (increased resorptions). This same oral dose given on gestation day 12, 13, 14 or 15 induced external malformations including cleft palate, micromelia and digital anomalies (brachydactyly, ectrodactyly, syndactyly).

    In pregnant rabbits orally administered ketoconazole, evidence of embryotoxicity (increased resorptions) was observed at 10 mg/kg (1.2 times the MRHD based on BSA comparisons) and higher and an increased incidence of skeletal abnormalities was observed at 40 mg/kg (4.8 times the MRHD based on BSA comparisons).

    8.2 Lactation

    Risk Summary

    There is no information available on the presence of ketoconazole in human milk, or the effects on the breastfed child, or the effects on milk production after topical application of EXTINA Foam to women who are breastfeeding. In animal studies ketoconazole was found in milk following oral administration. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for EXTINA Foam and any potential adverse effects on the breastfed infant from EXTINA Foam or from the underlying maternal condition.

    8.3 Females and Males of Reproductive Potential

    Infertility

    In animal fertility studies in rats and dogs, administration of oral doses of ketoconazole between 3-day and 3-month periods resulted in infertility that was reversible [see Nonclinical Toxicology (13.1)].

    8.4 Pediatric Use

    The safety and effectiveness of EXTINA Foam in pediatric patients less than 12 years of age have not been established.

    Of the 672 subjects treated with EXTINA Foam in the clinical trials, 44 (7%) were from 12 to 17 years of age. [See Clinical Studies (14)].

    8.5 Geriatric Use

    Of the 672 subjects treated with EXTINA Foam in the clinical trials, 107 (16%) were 65 years and over. Clinical trials of EXTINA Foam did not include sufficient numbers of subjects aged 65 and over to determine whether they respond differently than younger subjects.

  • 11 DESCRIPTION

    EXTINA Foam contains 2% ketoconazole USP, an antifungal agent, in a thermolabile hydroethanolic foam for topical application.

    The chemical name for ketoconazole is piperazine, 1-acetyl-4-[4-[[2-(2,4-dichlorophenyl) -2-(1H-imidazol-l-ylmethyl)-1,3-dioxolan-4-yl]methoxy]phenyl]-, cis- with the molecular formula C26H28Cl2N4O4 and a molecular weight of 531.43. The following is the chemical structure:

    Ketoconazole Structural Formula

    EXTINA Foam contains 20 mg of ketoconazole per gram in a thermolabile hydroethanolic foam vehicle consisting of cetyl alcohol, citric acid, ethanol (denatured with tert-butyl alcohol and brucine sulfate) 58%, polysorbate 60, potassium citrate, propylene glycol, purified water, and stearyl alcohol pressurized with a hydrocarbon (propane/butane) propellant.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    The mechanism of action of ketoconazole in the treatment of seborrheic dermatitis is not known.

    12.2 Pharmacodynamics

    The pharmacodynamics of EXTINA Foam has not been established.

    12.3 Pharmacokinetics

    In a bioavailability study, 12 subjects with moderate to severe seborrheic dermatitis applied 3 g of EXTINA Foam twice daily for 4 weeks. Circulating plasma levels of ketoconazole were < 6 ng/mL for a majority of subjects (75%), with a maximum level of 11 ng/mL observed in one subject.

    12.4 Microbiology

    Ketoconazole is an antifungal agent which inhibits the in vitro synthesis of ergosterol, a key sterol in the cell membrane of Malassezia furfur. The clinical significance of antifungal activity in the treatment of seborrheic dermatitis is not known.

  • 13 NONCLINICAL TOXICOLOGY

    13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility

    Long-term animal studies have not been performed to evaluate the carcinogenic or photo-carcinogenic potential of EXTINA Foam.

    In oral carcinogenicity studies in mice (18-months) and rats (24-months) at dose levels of 5, 20 and 80 mg/kg/day ketoconazole was not carcinogenic. The high dose in these studies was approximately 2.4 to 4.8 times the MRHD based on BSA comparisons. In a bacterial reverse mutation assay, ketoconazole did not express any mutagenic potential. In three in vivo assays (sister chromatid exchange in humans, dominant lethal and micronucleus tests in mice), ketoconazole did not exhibit any genotoxic potential.

    In animal fertility studies, oral ketoconazole impaired both male and female fertility in rats in a dose and duration dependent manner. In females, oral doses up to 40 mg/kg (2.4 times the MRHD based on BSA comparisons) had no effect on fertility, while doses of 75 mg/kg (4.5 times the MRHD based on BSA comparisons) and higher decreased the pregnancy rate and number of implantation sites. In male rats, oral dosing at 200 mg/kg/day (12 times the MRHD based on BSA comparisons) for three days decreased fertility and 400 mg/kg/day (24 times the MRHD based on BSA comparisons) for three days resulted in a complete loss of fertility. When administered for longer durations (up to 3 months), decreased fertility in male rats was observed at doses as low as 24 mg/kg/day (1.4 times the MRHD based on BSA comparisons). In male beagle dogs, an oral dose of 25 mg/kg/day ketoconazole for up to 4 weeks (5.2 times the MRHD based on BSA comparisons) resulted in decreased sperm motility, decreased sperm count, increased abnormal sperm and atrophy of the testes. These effects were reversed subsequent to withdrawal of treatment.

  • 14 CLINICAL STUDIES

    The safety and efficacy of EXTINA Foam were evaluated in a randomized, double-blind, vehicle-controlled trial in subjects 12 years and older with mild to severe seborrheic dermatitis. In the trial, 427 subjects received EXTINA Foam and 420 subjects received vehicle foam. Subjects applied EXTINA Foam or vehicle foam twice daily for 4 weeks to affected areas on the face, scalp, and/or chest. The overall disease severity in terms of erythema, scaling, and induration was assessed at Baseline and week 4 on a 5-point Investigator’s Static Global Assessment (ISGA) scale.

    Treatment success was defined as achieving a Week 4 (end of treatment) ISGA score of 0 (clear) or 1 (majority of lesions have individual scores for scaling, erythema, and induration that averages 1 [minimal or faint]) and at least two grades of improvement from baseline. The results are presented in Table 2. The database was not large enough to assess whether there were differences in effects in age, gender, or race subgroups.
