Side Effects & Drug Interactions

SIDE EFFECTS

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 clinical trials, 1227 subjects were treated with JUBLIA, 1161 for at least 24 weeks and 780 for 48 weeks. Adverse reactions reported within 48 weeks of treatment and in at least 1% of subjects treated with JUBLIA and those reported in subjects treated with the vehicle are presented in Table 1.

PRECAUTIONS

Patient Counseling Information

Advise the patient to read the FDA-approved patient labeling (Patient Information and Instructions for Use).

  • JUBLIA is for external use only and is not for ophthalmic, oral, or intravaginal use. It is for use on toenails and immediately adjacent skin only.
  • Apply JUBLIA once daily to clean dry toenails. Wait for at least 10 minutes after showering, bathing, or washing before applying.
  • Use JUBLIA only on the affected toenails, as directed by your healthcare provider.
  • Inform a healthcare professional if the area of application shows signs of persistent irritation (for example, redness, itching, swelling).
  • The impact of nail polish or other cosmetic nail products on the efficacy of JUBLIA has not been evaluated.
  • Flammable, avoid use near heat or open flame.

Nonclinical Toxicology

Carcinogenesis, Mutagenesis, Impairment Of Fertility

A 2-year dermal carcinogenicity study in mice was conducted with daily topical administration of 3%, 10% and 30% efinaconazole solution. Severe irritation was noted at the treatment site in all dose groups, which was attributed to the vehicle and confounded the interpretation of skin effects by efinaconazole. The high dose group was terminated at week 34 due to severe skin reactions. No drugrelated neoplasms were noted at doses up to 10% efinaconazole solution (248 times the MRHD based on AUC comparisons).

Efinaconazole 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 chromosome aberration assay) and one in vivo genotoxicity test (mouse peripheral reticulocyte micronucleus assay).

No effects on fertility were observed in male and female rats that were administered subcutaneous doses up to 25 mg/kg/day efinaconazole (279 times the MRHD based on AUC comparisons) prior to and during early pregnancy. Efinaconazole delayed the estrous cycle in females at 25 mg/kg/day but not at 5 mg/kg/day (56 times MRHD based on AUC comparisons).

Use In Specific Populations

Pregnancy

Pregnancy Category C

There are no adequate and well-controlled studies with JUBLIA in pregnant women. JUBLIA should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus.

Systemic embryofetal development studies were conducted in rats and rabbits. Subcutaneous doses of 2, 10 and 50 mg/kg/day efinaconazole were administered during the period of organogenesis (gestational days 6-16) to pregnant female rats. In the presence of maternal toxicity, embryofetal toxicity (increased embryofetal deaths, decreased number of live fetuses, and placental effects) was noted at 50 mg/kg/day [559 times the Maximum Recommended Human Dose (MRHD) based on Area Under the Curve (AUC) comparisons]. No embryofetal toxicity was noted at 10 mg/kg/day (112 times the MRHD based on AUC comparisons). No malformations were observed at 50 mg/kg/day (559 times the MRHD based on AUC comparisons).

Subcutaneous doses of 1, 5, and 10 mg/kg/day efinaconazole were administered during the period of organogenesis (gestational days 6-19) to pregnant female rabbits. In the presence of maternal toxicity, there was no embryofetal toxicity or malformations at 10 mg/kg/day (154 times the MRHD based on AUC comparisons).

In a pre- and post-natal development study in rats, subcutaneous doses of 1, 5 and 25 mg/kg/day efinaconazole were administered from the beginning of organogenesis (gestation day 6) 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 post-natal pup mortality) was noted at 25 mg/kg/day. No embryofetal toxicity was noted at 5 mg/kg/day (17 times the MRHD based on AUC comparisons). No effects on post-natal development were noted at 25 mg/kg/day (89 times the MRHD based on AUC comparisons).

Nursing Mothers

It is not known whether efinaconazole is excreted in human milk. After repeated subcutaneous administration, efinaconazole was detected in milk of nursing rats. Because many drugs are excreted in human milk, caution should be exercised when JUBLIA is administered to nursing women.

Pediatric Use

Safety and effectiveness of JUBLIA in pediatric subjects have not been established.

Geriatric Use

Of the total number of subjects in clinical trials of JUBLIA, 11.3% were 65 and over, while none were 75 and over. No overall differences in safety and effectiveness were observed between these subjects and younger subjects, and other reported clinical experience has not identified differences in responses between the elderly and the younger subjects, but greater sensitivity of some older individuals cannot be ruled out.

Clinical Pharmacology

CLINICAL PHARMACOLOGY

Mechanism Of Action

JUBLIA topical solution is an azole antifungal [see Microbiology].

Pharmacodynamics

The pharmacodynamics of JUBLIA is unknown.

Pharmacokinetics

Systemic absorption of efinaconazole in 18 adult subjects with severe onychomycosis was determined after application of JUBLIA once daily for 28 days to patients’ 10 toenails and 0.5 cm adjacent skin. The concentration of efinaconazole in plasma was determined at multiple time points over the course of 24- hour periods on days 1, 14, and 28. Efinaconazole mean ± SD plasma C on Day 28 was 0.67 ± 0.37 ng/mL and the mean ± SD AUC was 12.15 ± 6.91 ng*h/mL. The plasma concentration versus time profile at steady state was generally flat over a 24-hour dosing interval. In a separate study of healthy volunteers, the plasma half-life of efinaconazole following daily applications when applied to all 10 toenails for 7 days was 29.9 hours.

Drug Interactions

JUBLIA is considered a non-inhibitor of the CYP450 enzyme family. In in vitro studies using human liver microsomes, efinaconazole did not inhibit CYP1A2, CYP2A6, CYP2C8, CYP2C9, CYP2C19, CYP2D6, CYP2PE1 and CYP3A4 enzyme activities at expected clinical systemic concentrations. In vitro studies in human primary hepatocytes showed that efinaconazole did not induce CYP1A2 or CYP3A4 activities.

Microbiology

Mechanism Of Action

Efinaconazole is an azole antifungal. Efinaconazole inhibits fungal lanosterol 14α-demethylase involved in the biosynthesis of ergosterol, a constituent of fungal cell membranes.

Activity In Vitro and In Vivo

Efinaconazole has been shown to be active against isolates of the following microorganisms, both in vitro and in clinical infections. Efinaconazole exhibits in vitro minimum inhibitory concentrations (MICs) of 0.06 mcg/mL or less against most (≥90%) isolates of the following microorganisms:

Trichophyton rubrum
Trichophyton mentagrophytes

Mechanism Of Resistance

Efinaconazole drug resistance development was studied in vitro against T. mentagrophytes, T. rubrum and C. albicans. Serial passage of fungal cultures in the presence of sub-growth inhibitory concentrations of efinaconazole increased the MIC by up to 4-fold. The clinical significance of these in vitro results is unknown.

Clinical Studies

The safety and efficacy of once daily use of JUBLIA for the treatment of onychomycosis of the toenail were assessed in two 52-week prospective, multi-center, randomized, double-blind clinical trials in patients 18 years and older (18 to 70 years of age) with 20% to 50% clinical involvement of the target toenail, without dermatophytomas or lunula (matrix) involvement. The trials compared 48 weeks of treatment with JUBLIA to the vehicle solution. The Complete Cure rate was assessed at Week 52 (4 weeks after completion of therapy). Complete cure was defined as 0% involvement of the target toenail (no clinical evidence of onychomycosis of the target toenail) in addition to Mycologic Cure, defined as both negative fungal culture and negative KOH. Table 2 lists the efficacy results for trials 1 and 2.

Instructions for Use

JUBLIA (joo-blee-uh)
(efinaconazole) topical solution, 10%

Important information: JUBLIA is for use ontoenails and surrounding skin only. Do not use JUBLIA in your mouth, eyes or vagina.

Read the Instructions for Use that comes with JUBLIA before you start using it. Talk to your healthcare provider if you have any questions.

How to apply JUBLIA:

Your toenails should be clean and dry before you apply JUBLIA.

Step 1: Before you apply JUBLIA to your affected toenail, remove the cap from the JUBLIA bottle. (See Figure A).

Remove the cap  - Illustration

Step 2: Hold the bottle upside down directly over the affected toenail and allow the product to moisten the brush. By turning the bottle upside down, the entire brush will become wet with the drug solution. Apply one drop of JUBLIA onto the toenail. Do not squeeze the bottle or press/rub the brush firmly against the toenail while applying JUBLIA (See Figure B).

Apply one drop of JUBLIA onto the toenail  - Illustration

Step 3: For the big toenail, also apply a second drop to the end of the toenail by touching the tip of the moist brush to the end of the toenail (See Figure C). If needed, repeat step 2 to re-wet brush.

For the big toenail, also apply a second drop - Illustration

Step 4: Use the brush attached to the bottle to gently apply JUBLIA. The goal is to make sure that the entire toenail including the cuticle, folds of the skin next to the sides of the toenail, and underneath the nail are covered with the drug solution. (See Figure D). Pressing or rubbing firmly against the toenail while applying JUBLIA could cause brush deformation and over application of the drug solution.

Make sure that the entire toenail including the cuticle, folds of the skin next to the sides of the toenail, and underneath the nail are covered with the drug solution - Illustration

Step 5: Repeat Steps 2 to 4 to apply JUBLIA to each affected toenail.

Step 6: Let JUBLIA dry completely.

Step 7: After applying JUBLIA to your affected toenails, place the cap on the bottle and screw it on tightly.

Step 8: Wash your hands with soap and water after applying JUBLIA.
