Insulin glargine / lixisenatide Pregnancy Warnings

Benefit should outweigh risk US FDA pregnancy category: Not Assigned Risk Summary: Based on animal studies, there may be a risk to the fetus from exposure to lixisenatide. Comment: There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy; insulin therapy is considered a drug of choice during pregnancy.

Animal studies with lixisenatide have shown reproductive toxicity. Studies in pregnant rats and rabbits at doses of 1 and 6 times the recommended human dose, respectively, were associated with visceral closure and skeletal defects. Published studies with insulin glargine have not reported a clear association with major birth defects or miscarriage risk. Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, pre-eclampsia, spontaneous abortions, preterm delivery, still birth, and macrosomia related morbidity. There are no controlled data in human pregnancy. Patients with diabetes or a history of gestational diabetes should maintain good metabolic control before conception and during pregnancy. Insulin requirements may decrease during the first trimester; generally, increase during the second and third trimesters, and rapidly decline after delivery. Careful monitoring of glucose control is essential. US FDA pregnancy category Not Assigned: The US FDA has amended the pregnancy labeling rule for prescription drug products to require labeling that includes a summary of risk, a discussion of the data supporting that summary, and relevant information to help health care providers make prescribing decisions and counsel women about the use of drugs during pregnancy. Pregnancy categories A, B, C, D, and X are being phased out.

Insulin glargine / lixisenatide Breastfeeding Warnings

Benefit should outweigh risk Excreted into human milk: Insulin glargine (yes); Lixisenatide (unknown) Excreted into animal milk: Yes (lixisenatide)

Exogenous insulins, including insulin glargine appear to be excreted into breast milk. Insulin is a protein that is inactivated if taken by mouth. If absorbed, it would be destroyed in the digestive tract of the infant. There is no information on the presence of lixisenatide in human milk. In lactating rats, milk transfer of lixisenatide and its metabolites were low (9.4%) and levels of unchanged drug in the gastric contents of weaning offspring was negligible (0.01%). There is no information on the effects on the breastfed infant, or the effects on milk production with this combination drug, although use of insulin therapy should be considered compatible with breastfeeding.
