8 Use in Specific Populations

PLLR conversion; as below:

8.1 Pregnancy

Risk Summary

There are no studies with Miacalcin injection in pregnant women to inform a drug associated risk for birth defects or miscarriage. In an animal reproduction study, subcutaneous administration of calcitonin-salmon to pregnant rabbits during organogenesis at 4-18 times the recommended parenteral human dose caused a decrease in fetal birth weights. No adverse developmental outcome was observed in the rat with subcutaneous administration of calcitonin-salmon at 9 times the recommended human parenteral dose based on body surface area.

In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15-20%, respectively.

Data

Animal Data

Calcitonin-salmon has been shown to cause a decrease in fetal birth weights in rabbits when given by subcutaneous injection in doses 4 to 18 times the parenteral dose recommended for human use (of 54 International Units/m2). No embryo/fetal toxicities related to Miacalcin were reported from maternal subcutaneous daily doses in rats up to 80 International Units/kg/day from gestation day 6 to 15.

8.2 Lactation

PLLR conversion; as below:

Risk Summary

There is no information on the presence of calcitonin-salmon in human milk, the effects on the breastfed child, or the effects on milk production. Calcitonin has been shown to inhibit lactation in rats. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for Miacalcin injection and any potential adverse effects on the breastfed infant from Miacalcin injection or from the underlying maternal condition.
