Zelsuvmi Drug Information

ZELSUVMI™ is indicated for the topical treatment of molluscum contagiosum (MC) in adults and pediatric patients 1 year of age and older.

Important Preparation and Administration Instructions ZELSUVMI is supplied in a carton containing the following: Tube A containing berdazimer gel Tube B containing hydrogel Dosing guide Mix together equal amounts of gel from Tube A and Tube B before application. Do not premix or store mixed ZELSUVMI. Instruct the patient to refer to the ZELSUVMI “Instructions for Use” for detailed instructions on the preparation and administration of ZELSUVMI.

Recommended Dosage and Administration

Dispense equal amounts (0.5 mL) of gel from Tube A and Tube B on the dosing guide. Immediately put the caps back on Tube A and Tube B tightly. Mix together on the dosing guide.

Immediately apply ZELSUVMI as an even thin layer. Apply ZELSUVMI once daily to each MC lesion for up to 12 weeks. Wash hands after applying ZELSUVMI, unless hands are being treated.

Allow ZELSUVMI to dry for 10 minutes after application. Avoid application to uninvolved skin and avoid transfer of applied ZELSUVMI to other areas, including the eye. Avoid swimming, bathing, or washing for 1 hour after application of ZELSUVMI.

ZELSUVMI is for topical use only and not for ophthalmic, oral, or intravaginal use.

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. Adverse reactions reported by ≥1% of subjects and more frequently than vehicle-treated subjects are listed in Table 1.

Pregnancy Risk Summary There are no available data on ZELSUVMI use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage or other adverse maternal or fetal outcomes. In animal reproduction studies, oral administration of berdazimer to pregnant rats and rabbits increased malformations in the presence of severe maternal toxicity ( see Data ). The clinical relevance of this finding is unknown given the bioavailability of berdazimer following oral administration is significantly higher than topical application.

The available data do not allow the calculation of relevant comparisons between the systemic exposure of berdazimer observed in animal studies and the systemic exposure that would be expected in humans after topical use of ZELSUVMI. 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 respectively. Data Animal Data Systemic embryo-fetal development studies were conducted in rats and rabbits. In an embryo-fetal development study in rats, oral dose levels of 28, 95, or 189 mg/kg/day berdazimer were administered during the period of organogenesis.

Maternal mortality and elevated methemoglobin levels were noted in dams receiving doses of 95 and 189 mg/kg/day. The maternal no observable adverse effect level (NOAEL) was 28 mg/kg/day. Fetal skeletal malformations (changes in the lumbar and thoracic centra or arches, missing thoracic arches and centra, additional bone in the thoracic arches, missing lumbar centra and arches, and fused ribs) and visceral malformations (cleft palate) and decreased fetal weights were observed in litters from dams receiving 189 mg/kg/day.

The fetal NOAEL was 95 mg/kg/day. In an embryo-fetal development study in rabbits, oral dose levels of 47, 142, or 284 mg/kg/day berdazimer were administered during the period of organogenesis. Maternal mortality, aborted fetuses, adverse clinical observations, and elevated methemoglobin levels were noted in pregnant rabbits receiving doses of 142 and 284 mg/kg/day.

The maternal NOAEL was 47 mg/kg/day. Decreased fetal weights were noted from pregnant rabbits receiving 284 mg/kg/day. The fetal NOAEL was 142 mg/kg/day.

Pediatric Use The safety and effectiveness of ZELSUVMI for the topical treatment of MC have been established in pediatric patients 1 year of age and older. The safety and effectiveness of ZELSUVMI have not been established in pediatric patients younger than 1 year of age.
