PHARMACOKINETICS SECTION.

12.3 Pharmacokinetics. Luliconazole is the enantiomer of chiral molecule. The potential for interconversion between and enantiomers in humans has not been assessed. Information on the pharmacokinetics of luliconazole presented below refers to both enantiomer and enantiomer, if any, combined.Luliconazole is >99% protein bound in plasma.In PK trial, 12 subjects with moderate to severe tinea pedis and subjects with moderate to severe tinea cruris applied mean daily amount of approximately 3.5 grams of LUZU Cream, 1% to the affected and surrounding areas once daily for 15 days. Plasma concentrations of luliconazole on Day 15 were measurable in all subjects and fluctuated little during the 24-hour interval. In subjects with tinea pedis, the mean +- SD of the maximum concentration (Cmax) was 0.40 +- 0.76 ng/mL after the first dose and 0.93 +- 1.23 ng/mL after the final dose. The mean time to reach Cmax (Tmax) was 16.9 +- 9.39 hours after the first dose and 5.8 +- 7.61 hours after the final dose. Exposure to luliconazole, as expressed by area under the concentration time curve (AUC0-24), was 6.88 +- 14.50 nghr/mL after the first dose and 18.74 +- 27.05 nghr/mL after the final dose. In subjects with tinea cruris, the mean +- SD Cmax was 4.91 +- 2.51 ng/mL after the first dose and 7.36 +- 2.66 ng/mL after the final dose. The mean Tmax was 21.0 +- 5.55 hours after the first dose and 6.5 +- 8.25 hours after the final dose. Exposure to luliconazole, as expressed by AUC0-24, was 85.1 +- 43.69 nghr/mL after the first dose and 121.74 +- 53.36 nghr/mL after the final dose.PK data of luliconazole measured in adolescent subjects (12 to <18 years of age) with moderate to severe interdigital tinea pedis or moderate to severe tinea cruris as well as in subjects to <18 years of age with tinea corporis are described in Specific Populations below.Specific PopulationsPK of luliconazole was assessed in 30 adolescent subjects 12 to <18 years of age with moderate to severe interdigital tinea pedis (N=15) or moderate to severe tinea cruris (N=15). Subjects with tinea pedis applied approximately grams of LUZU Cream, 1% once daily to the affected area and adjacent skin for 15 days, while subjects with tinea cruris applied LUZU Cream, 1% once daily to the affected and adjacent skin for days.Generally, the systemic exposure of luliconazole was greater in the subjects with tinea cruris than tinea pedis. In subjects with tinea pedis, the systemic concentrations of luliconazole were quantifiable in all the subjects on Day and Day 15. The mean +- SD Cmax was 1.80 +- 1.86 ng/mL after the first dose on Day 1, and 3.93 +- 1.67 ng/mL and 3.27 +- 1.71 ng/mL on Days and 15, respectively. The mean +- SD AUC0-24 was 20.47 +- 14.47 nghr/mL after the first dose on Day 1, and 64.94 +- 32.47 nghr/mL and 60.38 +- 37.92 nghr/mL on Days and Day 15, respectively. Like in adult subjects, the mean plasma concentrations of luliconazole in adolescent subjects on Days and 15 were similar and fluctuated little during 24-hour interval. In subjects with moderate to severe tinea cruris, the systemic concentrations of luliconazole were quantifiable in all the subjects on Day 8. The mean +- SD Cmax was 9.80 +- 5.94 ng/mL after the first dose (Day 1) and 15.40 +- 13.62 ng/mL after the last dose (Day 8). The mean +- SD AUC0-24 was 157.07 +- 92.18 nghr/mL and 266.06 +- 236.07 nghr/mL, after the first dose (Day 1) and the last dose (Day 8). In subjects with tinea corporis, the systemic concentrations of luliconazole were assessed at pre-dose and at hours post-dose on the last day of treatment following once daily treatment with LUZU Cream, 1% for days. The systemic concentrations were quantifiable in all the 12 subjects and the mean +- SD daily dose of LUZU Cream, 1% was 2.84 +- 1.82 g. The mean +- SD concentrations of luliconazole at 15 minutes prior to dosing and at hours post-dose on Day were 4.63 +- 2.93 ng/mL and 4.84 +- 3.33 ng/mL, respectively.Drug InteractionsResults of in vitro studies indicated that therapeutic doses of LUZU Cream, 1% did not inhibit cytochrome P450 (CYP) enzymes 1A2, 2C9 and 2D6, but can inhibit the activity of CYP2B6, 2C8, 2C19, and 3A4. The most sensitive enzyme, CYP2C19, was further evaluated in an in vivo study using omeprazole as probe substrate in adult subjects with moderate to severe interdigital tinea pedis and tinea cruris. The results showed that LUZU Cream, 1% applied at daily amount of approximately grams increased the omeprazole systemic exposure (AUC) by approximately 30% compared to the exposure of omeprazole administered alone. LUZU Cream, 1% is considered weak inhibitor of CYP2C19. For tinea cruris, extrapolation from both in vitro inhibition studies and in vivo data in adults to the adolescent subjects showed that in some subjects, levels of luliconazole can approach or exceed those required to be moderate inhibitor of CYP2C19.Results of in vitro studies indicated that therapeutic doses of LUZU Cream, 1% did not induce CYP1A2, 2B6, and 3A4.

CLINICAL STUDIES SECTION.

ADVERSE REACTIONS SECTION.

6 ADVERSE REACTIONS. The most common adverse reactions observed in clinical trials were application site reactions, which occurred in less than 1% of subjects. (6.1) To report SUSPECTED ADVERSE REACTIONS, contact Bausch Health US, LLC at 1-800-321-4576 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 drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.In three Phase clinical trials, 616 subjects were exposed to LUZU Cream, 1%: 305 with interdigital tinea pedis and 311 subjects with tinea cruris. Subjects with interdigital tinea pedis or tinea cruris applied LUZU Cream, 1% or vehicle cream once daily for 14 days or days, respectively, to affected and adjacent areas. During clinical trials with LUZU Cream, 1%, the most common adverse reactions were application site reactions which occurred in less than 1% of subjects in both the LUZU and vehicle arms. Most adverse reactions were mild in severity.A post-approval clinical trial was conducted in 75 subjects age to <18 years old with tinea corporis. The adverse reactions in the LUZU Cream, 1% treated population were similar to the vehicle treated population.. 6.2 Postmarketing Experience. The following adverse reactions have been identified during postmarketing use of luliconazole cream, 1%: contact dermatitis and cellulitis. Because these reactions are reported voluntarily from population of uncertain size, it is not always possible to reliably estimate their frequency or establish causal relationship to drug exposure.

CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. Long-term studies to evaluate the carcinogenic potential of LUZU Cream, 1% have not been conducted.Luliconazole revealed no evidence of mutagenic or clastogenic potential based on the results of two in vitro genotoxicity tests (Ames assay and Chinese hamster lung cell chromosomal aberration assay) and one in vivo genotoxicity test (mouse bone marrow micronucleus test).In fertility study in rats, subcutaneous doses of 1, and 25 mg/kg/day luliconazole were administered prior to and during mating and through early pregnancy. Treatment-related effects on reproductive function were noted in females (decreased live embryos and decreased corpus luteum) at and 25 mg/kg/day and males (decreased sperm counts) at 25 mg/kg/day. No treatment-related effects on fertility or reproductive function were noted at mg/kg/day (0.1x MRHD based on BSA comparisons).

Mechanism of Action. Luliconazole is an antifungal that belongs to the azole class. Although the exact mechanism of action against dermatophytes is unknown, luliconazole appears to inhibit ergosterol synthesis by inhibiting the enzyme lanosterol demethylase. Inhibition of this enzymes activity by azoles results in decreased amounts of ergosterol, constituent of fungal cell membranes, and corresponding accumulation of lanosterol.. Mechanism of Resistance. To date, mechanism of resistance to luliconazole has not been described.LUZU Cream, 1% has been shown to be active against most isolates of the following fungi, both in vitro and in clinical infections as described in the INDICATIONS AND USAGE section: Trichophyton rubrum Epidermophyton floccosum.

PREGNANCY SECTION.

8.1 Pregnancy. Risk SummaryThere are no available data with LUZU Cream, 1% use in pregnant women to inform drug-associated risk for major birth defects and miscarriage. In animal reproduction studies with pregnant rats and rabbits, there were no adverse developmental effects observed with subcutaneous administration of luliconazole during organogenesis at doses up to and 24 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 have 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 to 4% and 15 to 20%, respectively.DataAnimal DataThe animal multiples of human exposure calculations were based on daily dose body surface area (BSA) comparisons (mg/m2) for the reproductive toxicology studies described in this section and in Section 13.1. The maximum recommended human dose (MRHD) was set at g 1% cream per day (1.33 mg/kg/day for 60 kg individual, which is equivalent to 49.2 mg/m2/day).Systemic embryofetal development studies were conducted in rats and rabbits. Subcutaneous doses of 1, and 25 mg/kg/day luliconazole were administered during the period of organogenesis (gestational days 7-17) to pregnant female rats. No treatment-related effects on maternal toxicity or malformations were noted at 25 mg/kg/day (3 times the MRHD based on BSA comparisons). Increased incidences of skeletal variation (14th rib) were noted at 25 mg/kg/day. No treatment-related effects on skeletal variation were noted at mg/kg/day (0.6 times the MRHD based on BSA comparisons).Subcutaneous doses of 4, 20 and 100 mg/kg/day luliconazole were administered during the period of organogenesis (gestational days 6-18) to pregnant female rabbits. No treatment-related effects on maternal toxicity, embryofetal toxicity or malformations were noted at 100 mg/kg/day (24 times the MRHD based on BSA comparisons).In pre- and postnatal development study in rats, subcutaneous doses of 1, and 25 mg/kg/day luliconazole were administered from the beginning of organogenesis (gestation day 7) through the end of lactation (lactation day 20). In the presence of maternal toxicity, embryofetal toxicity (increased prenatal pup mortality, reduced live litter sizes and increased postnatal pup mortality) was noted at 25 mg/kg/day. No embryofetal toxicity was noted at mg/kg/day (0.6 times the MRHD based on BSA comparisons).

6.1 Clinical Trials Experience. Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.In three Phase clinical trials, 616 subjects were exposed to LUZU Cream, 1%: 305 with interdigital tinea pedis and 311 subjects with tinea cruris. Subjects with interdigital tinea pedis or tinea cruris applied LUZU Cream, 1% or vehicle cream once daily for 14 days or days, respectively, to affected and adjacent areas. During clinical trials with LUZU Cream, 1%, the most common adverse reactions were application site reactions which occurred in less than 1% of subjects in both the LUZU and vehicle arms. Most adverse reactions were mild in severity.A post-approval clinical trial was conducted in 75 subjects age to <18 years old with tinea corporis. The adverse reactions in the LUZU Cream, 1% treated population were similar to the vehicle treated population.

Store at 20 to 25C (68 to 77F); excursions permitted from 15 to 30C (59 to 86F) [see USP Controlled Room Temperature].

TERATOGENIC EFFECTS SECTION.

Risk SummaryThere are no available data with LUZU Cream, 1% use in pregnant women to inform drug-associated risk for major birth defects and miscarriage. In animal reproduction studies with pregnant rats and rabbits, there were no adverse developmental effects observed with subcutaneous administration of luliconazole during organogenesis at doses up to and 24 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 have 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 to 4% and 15 to 20%, respectively.DataAnimal DataThe animal multiples of human exposure calculations were based on daily dose body surface area (BSA) comparisons (mg/m2) for the reproductive toxicology studies described in this section and in Section 13.1. The maximum recommended human dose (MRHD) was set at g 1% cream per day (1.33 mg/kg/day for 60 kg individual, which is equivalent to 49.2 mg/m2/day).Systemic embryofetal development studies were conducted in rats and rabbits. Subcutaneous doses of 1, and 25 mg/kg/day luliconazole were administered during the period of organogenesis (gestational days 7-17) to pregnant female rats. No treatment-related effects on maternal toxicity or malformations were noted at 25 mg/kg/day (3 times the MRHD based on BSA comparisons). Increased incidences of skeletal variation (14th rib) were noted at 25 mg/kg/day. No treatment-related effects on skeletal variation were noted at mg/kg/day (0.6 times the MRHD based on BSA comparisons).Subcutaneous doses of 4, 20 and 100 mg/kg/day luliconazole were administered during the period of organogenesis (gestational days 6-18) to pregnant female rabbits. No treatment-related effects on maternal toxicity, embryofetal toxicity or malformations were noted at 100 mg/kg/day (24 times the MRHD based on BSA comparisons).In pre- and postnatal development study in rats, subcutaneous doses of 1, and 25 mg/kg/day luliconazole were administered from the beginning of organogenesis (gestation day 7) through the end of lactation (lactation day 20). In the presence of maternal toxicity, embryofetal toxicity (increased prenatal pup mortality, reduced live litter sizes and increased postnatal pup mortality) was noted at 25 mg/kg/day. No embryofetal toxicity was noted at mg/kg/day (0.6 times the MRHD based on BSA comparisons). No treatment effects on postnatal development were noted at 25 mg/kg/day (3 times the MRHD based on BSA comparisons).

No treatment effects on postnatal development were noted at 25 mg/kg/day (3 times the MRHD based on BSA comparisons).. 8.2 Lactation Risk SummaryThere is no information available on the presence of luliconazole in human milk, the effects of the drug on the breastfed infant, or the effects of the drug on milk production after topical application of LUZU Cream, 1% to women who are breastfeeding. LUZU Cream, 1% has low systemic absorption. The lack of clinical data during lactation precludes clear determination of the risk of LUZU Cream, 1% to an infant during lactation. Therefore, the developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for LUZU Cream, 1% and any potential adverse effects on the breastfed infant from LUZU Cream, 1% or from the underlying maternal condition.. 8.4 Pediatric Use. The safety and effectiveness of LUZU Cream, 1% in pediatric patients 12 to <18 years of age with tinea pedis and tinea cruris have been established by evidence from well-controlled trials in adult and pediatric subjects and pharmacokinetic (PK) study in pediatric subjects [see Clinical Pharmacology (12.3) and Clinical Studies (14)]. The safety and effectiveness of LUZU Cream, 1% in pediatric patients to <18 years of age with tinea corporis have been established by evidence from well-controlled trial in pediatric subjects [see Clinical Pharmacology (12.3) and Clinical Studies (14)]. 8.5 Geriatric Use. Of the total number of subjects in clinical studies of LUZU Cream, 1%, 8% were 65 and over, while 1.4% were 75 and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and younger patients, but greater sensitivity of some older individuals cannot be ruled out.
