The treated area may be covered with a sterile bandage or gauze dressing.

3 DOSAGE FORMS AND STRENGTHS 

Cream: 1%, pale yellow cream. Each gram of XEPI contains 10 mg of ozenoxacin.

4 CONTRAINDICATIONS 

None.

5 WARNINGS AND PRECAUTIONS 

Potential for Microbial Overgrowth 

The prolonged use of XEPI may result in overgrowth of nonsusceptible bacteria and fungi. If such infections occur during therapy, discontinue use and institute appropriate supportive measures.

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 safety profile of XEPI was assessed in two clinical trials (Trial 1 and Trial 2) in 362 adult and pediatric patients two months of age and older with impetigo. The patients used at least one dose from a 5-day, twice a day regimen of XEPI. Control groups included 361 patients who used placebo and 152 patients who used retapamulin ointment. The median age of the patients enrolled in the clinical trials was 10 years; 3 % of patients were 2 months to less than 2 years of age, 55 % of patients were 2 to less than 12 years of age, 11 % of patients were 12 to less than 18 years of age, and 31 % of patients were 18 years of age or older.

Adverse reactions (rosacea and seborrheic dermatitis) were reported in 1 adult patient treated with XEPI.

8 USE IN SPECIFIC POPULATIONS 

8.1 Pregnancy

Risk Summary 

There are no available data on the use of XEPI in pregnant women to inform a drug associated risk. Systemic absorption of XEPI in humans is negligible following topical administration of XEPI (up to twice the concentration of the marketed formulation) [see Clinical Pharmacology (12.3)]. Due to the negligible systemic exposure, it is not expected that maternal use of XEPI will result in fetal exposure to the drug.

Animal reproduction studies were not conducted with XEPI. However, toxicity studies conducted in pregnant rats and rabbits administered the oral form of ozenoxacin showed no significant adverse developmental effects (at >10,000 times the maximum human plasma concentration seen with dermal application of ozenoxacin).

The estimated background risk of major birth defects and miscarriage for the indicated population are unknown. 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.

8.2 Lactation

Risk Summary 

No data are available regarding the presence of ozenoxacin in human milk, and the effects of ozenoxacin on the breastfed infant or on milk production. However, breastfeeding is not expected to result in exposure of the child to ozenoxacin due to the negligible systemic absorption of ozenoxacin in humans following topical administration of XEPI. The developmental and health benefits of breastfeeding should be considered along with the mother's clinical need for XEPI and any potential adverse effects on the breast-fed child from XEPI or from the underlying maternal condition.

8.4 Pediatric Use
