VEREGEN- sinecatechins ointment

1 Indications And Usage

1.1 Indication

Veregen is indicated for the topical treatment of external genital and perianal warts (Condylomata acuminata) in immunocompetent patients 18 years and older.

1.2 Limitations Of Use

The safety and effectiveness of Veregen have not been established for treatment beyond 16-weeks or for multiple treatment courses.

The safety and effectiveness of Veregen in immunosuppressed patients have not been established.

2 Dosage And Administration

2.1 General Dosing Information

Veregen is to be applied three times per day to all external genital and perianal warts.

Apply about an 0.5 cm strand of the Veregen to each wart using the finger(s), dabbing it on to ensure complete coverage and leaving a thin layer of the ointment on the warts. Patients should wash their hands before and after application of Veregen.

It is not necessary to wash off the ointment from the treated area prior to the next application.

Veregen® is not for ophthalmic, oral, intravaginal, or intra-anal use.

2.2 Treatment Period

Treatment with Veregen should be continued until complete clearance of all warts, however no longer than 16 weeks.

Local skin reactions (e.g. erythema) at the treatment site are frequent. Nevertheless, treatment should be continued when the severity of the local skin reaction is acceptable.

8 Use In Specific Populations

8.1 Pregnancy

Risk Summary

There are no available data on Veregen use in pregnant women to evaluate for a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. In animal reproduction studies, sinecatechins did not cause malformations, but did affect the developing fetus in the presence of maternal toxicity when given to pregnant rabbits and rats by intravaginal or systemic routes of administration during the period of organogenesis (see Data). The available data do not allow the calculation of relevant comparisons between the systemic exposure of sinecatechins observed in the animal studies to the systemic exposure that would be expected in humans after topical use of Veregen.

Data

Embryo-fetal development studies were conducted in rats and rabbits using intravaginal and systemic routes of administration, respectively. Oral administration of sinecatechins during the period of organogenesis (gestational Days 6 to 15 in rats or 6 to 18 in rabbits) did not cause treatment-related malformations or effects on embryo-fetal development at doses of up to 1,000 mg/kg/day.

In the presence of maternal toxicity (characterized by marked local irritation at the administration sites and decreased body weight and food consumption) in pregnant female rabbits, subcutaneous doses of 12 and 36 mg/kg/day of sinecatechins during the period of organogenesis (gestational Days 6 to 19) resulted in corresponding influences on fetal development including reduced fetal body weights and delays in skeletal ossification. No treatment-related effects on embryo-fetal development were noted at 4 mg/kg/day. No malformations were noted at any of the doses evaluated in this study.

A combined fertility and embryo-fetal development study using daily vaginal administration of Veregen to rats from Day 4 before mating and throughout mating until Day 17 of gestation did not show treatment-related effects on fertility, malformations, or embryo-fetal development at doses up to 0.15 mL/rat/day. This dose corresponds to approximately 150 mg/rat/day.

A pre- and post-natal development study was conducted in rats using vaginal administration of Veregen at doses of 0.05, 0.10 and 0.15 mL/rat/day from Day 6 of gestation through parturition and lactation. The high and intermediate dose levels of 0.15 and 0.10 mL/rat/day resulted in an increased mortality of the F0 dams, associated with indications of parturition complications. The high dose level of 0.15 mL/rat/day also resulted in an increased incidence of stillbirths. There were no other treatment-related effects on pre- and post-natal development, growth, reproduction and fertility at any dose tested.

8.2 Lactation

Risk Summary

There are no data on the presence of sinecatechins in human or animal milk, the effects on the breastfed child, or the effects on milk production. After topical application, Veregen concentrations in plasma are low and therefore concentrations in human breast milk are likely to be low [see Clinical Pharmacology (12.3)]. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Veregenand any potential adverse effects on the breast-fed child from Veregenor from the underlying maternal condition.

8.4 Pediatric Use

Safety and effectiveness in pediatric patients have not been established.

8.5 Geriatric Use

Seven patients (1.4%), older than 65 years of age were treated with Veregen in clinical studies. This, however, is an insufficient number of subjects to determine whether they respond differently from younger subjects.

11 Description

Veregen (sinecatechins) Ointment, 15% is a botanical drug product for topical use. The drug substance in Veregen is sinecatechins, which is a partially purified fraction of the water extract of green tea leaves from Camellia sinensis (L.) O Kuntze, and is a mixture of catechins and other green tea components. Catechins constitute 85 to 95% (by weight) of the total drug substance which includes more than 55% of Epigallocatechin gallate (EGCg), other catechin derivatives such as Epicatechin (EC), Epigallocatechin (EGC), Epicatechin gallate (ECg), and some additional minor catechin derivatives i.e. Gallocatechin gallate (GCg), Gallocatechin (GC), Catechin gallate (Cg), and Catechin (C). In addition to the known catechin components, it also contains gallic acid, caffeine, and theobromine which together constitute about 2.5% of the drug substance. The remaining amount of the drug substance contains undefined botanical constituents derived from green tea leaves.

12 Clinical Pharmacology

12.1 Mechanism Of Action

The mode of action of Veregen involved in the clearance of genital and perianal warts is unknown. In vitro, sinecatechins had anti-oxidative activity; the clinical significance of this finding is unknown.

12.2 Pharmacodynamics

The pharmacodynamics of Veregen is unknown.

12.3 Pharmacokinetics

13 Nonclinical Toxicology

13.1 Carcinogenesis, Mutagenesis, Impairment Of Fertility

In an oral (gavage) carcinogenicity study, sinecatechins was administered daily for 26 weeks to p53 transgenic mice at doses up to 500 mg/kg/day. Treatment with sinecatechins was not associated with an increased incidence of either neoplastic or non-neoplastic lesions in the organs and tissues examined. Veregen has not been evaluated in a dermal carcinogenicity study.

Sinecatechins was negative in the Ames test, in vivo rat micronucleus assay, UDS test, and transgenic mouse mutation assay, but positive in the mouse lymphoma mutation assay.

Daily vaginal administration of Veregen to rats from Day 4 before mating and throughout mating until Day 17 of gestation did not cause adverse effects on mating performance and fertility at doses up to 0.15 mL/rat/day.

14 Clinical Studies

Two randomized, double-blind, vehicle-controlled trials were performed to investigate the safety and efficacy of Veregen in the treatment of immunocompetent subjects 18 years of age and older with external genital and perianal warts. The subjects applied the ointment 3 times daily for up to 16 weeks or until complete clearance of all warts (baseline and new warts occurring during treatment).
