8 Use in Specific Populations

8.1 Pregnancy

(Pregnancy and Lactation Labeling Rule (PLLR) Conversion; Additions and/or revisions are underlined)

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. 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.

8.2 Lactation

(Pregnancy and Lactation Labeling Rule (PLLR) Conversion; Additions and/or revisions are underlined)

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.The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Veregen® and any potential adverse effects on the breast-fed child from Veregen® or from the underlying maternal condition.
