CARCINOGENESIS & MUTAGENESIS & IMPAIRMENT OF FERTILITY SECTION.

13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility. In an oral carcinogenicity study in Sprague-Dawley rats, oral doses of 12.5, 25, and 50 mg/kg/day tavaborole were administered to rats once daily for 104 weeks. No drug related neoplastic findings were noted at oral doses up to 50 mg/kg/day tavaborole (14 times the MRHD based on AUC comparisons).In dermal carcinogenicity study in CD-1 mice, topical doses of 5%, 10%, and 15% tavaborole solution were administered to mice once daily for 104 weeks. No drug related neoplastic findings were noted at topical doses up to 15% tavaborole solution (89 times the MRHD based on AUC comparisons).Tavaborole revealed no evidence of mutagenic or clastogenic potential based on the results of two in vitro genotoxicity tests (Ames assay and Human lymphocyte chromosomal aberration assay) and one in vivo genotoxicity test (rat micronucleus assay).No effects on fertility were observed in male and female rats that were administered oral doses up to 300 mg/kg/day tavaborole (107 times the MRHD based on AUC comparisons) prior to and during early pregnancy.

CLINICAL PHARMACOLOGY SECTION.

12 CLINICAL PHARMACOLOGY. 12.1 Mechanism of Action. Tavaborole topical solution is an oxaborole antifungal [see Clinical Pharmacology (12.4)].. 12.2 Pharmacodynamics. At therapeutic doses, tavaborole topical solution is not expected to prolong QTc to any clinically relevant extent.. 12.3 Pharmacokinetics. Tavaborole undergoes extensive metabolism. Renal excretion is the major route of elimination of the metabolites.In clinical pharmacology trial of six healthy adult male volunteers who received single topical application of 5% 14C-tavaborole solution, tavaborole conjugates and metabolites were shown to be excreted primarily in the urine. The pharmacokinetics (PK) of tavaborole was investigated in 24 adult subjects with distal subungual onychomycosis involving at least toenails (including at least great toenail) following single dose and 2-week daily topical application of 200 uL of 5% solution of tavaborole to all ten toenails and mm of skin surrounding each toenail. Steady state was achieved after 14 days of dosing. After single dose, the mean (+- standard deviation) peak concentration (Cmax) of tavaborole was 3.5 +- 2.3 ng/mL (n=21 with measurable concentrations, range 0.618-10.2 ng/mL, LLOQ=0.5 ng/mL), and the mean AUC last +- SD was 44.4 +- 25.5 nghr/mL (n=21). After weeks of daily dosing, the mean Cmax+- SD was 5.2 +- 3.5 ng/mL (n=24, range 1.5-12.8 ng/mL), and the mean AUC +- SD was 75.8 +- 44.5 nghr/mL. In another study PK of tavaborole was investigated in 22 subjects aged 12 years to less than 17 years with distal subungual onychomycosis involving at least toenails (including at least great toenail with at least 20% involvement) following once daily application of 5% solution of tavaborole to all ten toenails and mm of skin surrounding each toenail for 29 days. On Day 29, the mean +- SD max was 5.9 +- 4.9 ng/mL (n=21 with measurable concentrations, range 1.0 -16.4 ng/mL, LLOQ=0.5 ng/mL), and the mean +- SD AUC 0-24 was 76.0 +- 62.5 nghr/mL. Drug Interaction Studies. In Vitro StudiesIn vitro studies have shown that tavaborole, at therapeutic concentrations, neither inhibits nor induces cytochrome P450 (CYP450) enzymes.. 12.4 Microbiology. Mechanism of ActionThe mechanism of action of tavaborole is inhibition of fungal protein synthesis. Tavaborole inhibits protein synthesis by inhibition of an aminoacyl-transfer ribonucleic acid (tRNA) synthetase (AARS).. Activity in vitro and in clinical infectionsTavaborole has been shown to be active against most strains of the following microorganisms, both in vitro and in clinical infections [see Indications and Usage (1)]: Trichophyton rubrumTrichophyton mentagrophytes. Mechanism of ResistanceTrichophyton mentagrophytes and Trichophyton rubrum strains from isolates collected in the clinical trials have not demonstrated resistance following repeated exposure to tavaborole.

CLINICAL STUDIES SECTION.

14 CLINICAL STUDIES. The efficacy and safety of tavaborole topical solution was evaluated in two multicenter, double-blind, randomized, vehicle-controlled trials. Tavaborole topical solution or vehicle was applied once daily for 48 weeks in subjects with 20% to 60% clinical involvement of the target toenail, without dermatophytomas or lunula (matrix) involvement.A total of 1194 subjects (795 tavaborole topical solution, 399 Vehicle) 18 to 88 years of age, 82% male, 84% white, participated in these two trials. Efficacy assessments were made at 52 weeks following 48-week treatment period.The Complete Cure efficacy endpoint included negative mycology (negative KOH wet mount and negative fungal culture) and Completely Clear Nail (no clinical evidence of onychomycosis as evidenced by normal toenail plate, no onycholysis, and no subungual hyperkeratosis).

PREGNANCY SECTION.

8.1 Pregnancy. Risk SummaryThere are no available data on tavaborole topical solution use in pregnant women to inform drug associated risk for major birth defects, miscarriage or adverse maternal or fetal outcomes. In oral animal reproductive studies, administration of tavaborole during the period of organogenesis resulted in embryofetal toxicity and malformations at 570 times the Maximum Recommended Human Dose (MRHD) based on Area Under the Curve (AUC) comparisons in rats and embryofetal toxicity at 155 times the MRHD based on AUC comparisons in rabbits. Embryofetal toxicity was noted following dermal administration in rabbits up to 36 times the MRHD based on AUC comparisons 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. Oral Administration:In an oral embryofetal development study in rats, oral doses of 30, 100, and 300 mg/kg/day tavaborole were administered during the period of organogenesis (gestational days 6-19) to pregnant female rats. In the presence of maternal toxicity, embryofetal toxicity (increased embryofetal resorption and/or deaths) and drug-related skeletal malformations and variations suggestive of delayed development (i.e., delay in ossification) were noted in fetuses at 300 mg/kg/day tavaborole [570 times the MRHD based on AUC comparisons]. No developmental toxicity was noted in rats at 100 mg/kg/day tavaborole (26 times the MRHD based on AUC comparisons). In an oral embryofetal development study in rabbits, oral doses of 15, 50, and 150 mg/kg/day tavaborole were administered during the period of organogenesis (gestational days 7-19) to pregnant female rabbits. In the presence of maternal toxicity, excessive embryofetal mortality due to post-implantation loss was noted at 150 mg/kg/day tavaborole. No drug related malformations were noted in rabbits at 150 mg/kg/day tavaborole (155 times the MRHD based on AUC comparisons). No embryofetal mortality was noted in rabbits at 50 mg/kg/day tavaborole (16 times the MRHD based on AUC comparisons). In an oral pre-and post-natal development study in rats, oral doses of 15, 60, and 100 mg/kg/day tavaborole were administered from the beginning of organogenesis (gestation day 6) through the end of lactation (lactation day 20). In the presence of minimal maternal toxicity, no embryofetal toxicity or effects on postnatal development were noted at 100 mg/kg/day (29 times the MRHD based on AUC comparisons). Topical administration:In dermal embryofetal development study in rabbits, topical doses of 1%, 5%, and 10% tavaborole solution were administered during the period of organogenesis (gestational days 6-28) to pregnant female rabbits. dose dependent increase in dermal irritation at the treatment site was noted at 5% and 10% tavaborole solution. decrease in fetal bodyweight was noted at 10% tavaborole solution. No drug related malformations were noted in rabbits at 10% tavaborole solution (36 times the MRHD based on AUC comparisons). No embryofetal toxicity was noted in rabbits at 5% tavaborole solution (26 times the MRHD based on AUC comparisons).

No developmental toxicity was noted in rats at 100 mg/kg/day tavaborole (26 times the MRHD based on AUC comparisons). In an oral embryofetal development study in rabbits, oral doses of 15, 50, and 150 mg/kg/day tavaborole were administered during the period of organogenesis (gestational days 7-19) to pregnant female rabbits. In the presence of maternal toxicity, excessive embryofetal mortality due to post-implantation loss was noted at 150 mg/kg/day tavaborole. No drug related malformations were noted in rabbits at 150 mg/kg/day tavaborole (155 times the MRHD based on AUC comparisons). No embryofetal mortality was noted in rabbits at 50 mg/kg/day tavaborole (16 times the MRHD based on AUC comparisons). In an oral pre-and post-natal development study in rats, oral doses of 15, 60, and 100 mg/kg/day tavaborole were administered from the beginning of organogenesis (gestation day 6) through the end of lactation (lactation day 20). In the presence of minimal maternal toxicity, no embryofetal toxicity or effects on postnatal development were noted at 100 mg/kg/day (29 times the MRHD based on AUC comparisons). Topical administration:In dermal embryofetal development study in rabbits, topical doses of 1%, 5%, and 10% tavaborole solution were administered during the period of organogenesis (gestational days 6-28) to pregnant female rabbits. dose dependent increase in dermal irritation at the treatment site was noted at 5% and 10% tavaborole solution. decrease in fetal bodyweight was noted at 10% tavaborole solution. No drug related malformations were noted in rabbits at 10% tavaborole solution (36 times the MRHD based on AUC comparisons). No embryofetal toxicity was noted in rabbits at 5% tavaborole solution (26 times the MRHD based on AUC comparisons). 8.2 Lactation. Risk SummaryThere is no information available on the presence of tavaborole 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 tavaborole topical solution to women who are breastfeeding. tavaborole topical solution is systemically absorbed. The lack of clinical data during lactation precludes clear determination of the risk of tavaborole topical solution to breastfed infant. Therefore, the developmental and health benefits of breastfeeding should be considered along with the mothers clinical need for tavaborole topical solution and any potential adverse effects on the breastfed child from tavaborole topical solution or from the underlying maternal condition.. 8.4 Pediatric Use. The safety and efficacy of tavaborole topical solution were established in patients years of age and older. Use of tavaborole topical solution in these age groups is supported by evidence from adequate and well-controlled studies of tavaborole topical solution in adults with additional data from an open-label pharmacokinetics study of tavaborole in subjects 12 years to less than 17 years old see Clinical Pharmacology (12.3) ]. 8.5 Geriatric Use. In clinical trials of 791 subjects who were exposed to tavaborole topical solution, 19% were 65 years of age and over, while 4% were 75 years of age and over. No overall differences in safety or effectiveness were observed between these subjects and younger subjects, but greater sensitivity of some older individuals cannot be ruled out.
