Insulin detemir

Pregnancy

8.1 Pregnancy Risk Summary Available data from published studies and postmarketing case reports with LEVEMIR use in pregnant women have not identified a drug-associated risk of major birth defects, miscarriage, or adverse maternal or fetal outcomes. In a randomized, parallel-group, open-label clinical trial that included 152 pregnant women with type 1 diabetes who were administered LEVEMIR once or twice daily, beginning in gestational weeks 8 to 12 or prior to conception, no clear evidence of maternal or fetal risk associated with LEVEMIR was observed (see Data). There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy (see Clinical Considerations). Animal reproduction studies were conducted in non-diabetic pregnant rats and rabbits with insulin detemir administration at 3 and 135 times the human dose of 0.5 units/kg/day, respectively, throughout pregnancy. Overall, the effects of insulin detemir did not generally differ from those observed with regular human insulin (see Data) . In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. The estimated background risk of major birth defects is 6 to 10% in women with pre-gestational diabetes with a peri-conceptional HbA 1c >7 and has been reported to be as high as 20 to 25% in women with a peri-conceptional HbA 1c >10. The estimated background risk of miscarriage for the indicated population is unknown. Clinical Considerations Disease-Associated Maternal and/or Embryo/Fetal Risk Hypoglycemia and hyperglycemia occur more frequently during pregnancy in patients with pre-gestational diabetes. Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, preeclampsia, spontaneous abortions, preterm delivery, and delivery complications. Poorly controlled diabetes increases the fetal risk for major birth defects, stillbirth, and macrosomia-related morbidity. Data Human Data In an open-label clinical trial, pregnant females with type 1 diabetes (n=310) were treated with LEVEMIR (once or twice daily) or NPH insulin (once, twice, or thrice daily); both groups also received preprandial insulin aspart. Approximately half of the study participants in each arm were randomized as pregnant and were exposed to NPH or to other insulins prior to conception and in the first 8 weeks of gestation. The rates of preeclampsia observed in the study were within expected rates for pregnancy complicated by diabetes. No differences in pregnancy outcomes or the health of the fetus and newborn were seen between the two groups. In this study, the proportion of subjects with severe hypoglycemia and non-severe hypoglycemia was similar between the two treatment arms; for the definitions of severe hypoglycemia and non-severe hypoglycemia [see Adverse Reactions ( 6.1 )]. In about a quarter of infants, LEVEMIR was detected in the infant cord blood at levels above the lower level of quantification (<25 pmol/L). Animal Data In a fertility and embryonic development study, insulin detemir was administered to female rats before mating, during mating, and throughout pregnancy at doses up to 300 nmol/kg/day (3 times a human dose of 0.5 units/kg/day, based on plasma area under the curve (AUC) ratio). Doses of 150 and 300 nmol/kg/day produced numbers of litters with visceral anomalies. Doses up to 900 nmol/kg/day (approximately 135 times a human dose of 0.5 units/kg/day based on AUC ratio) were given to rabbits during organogenesis. Drug and dose related increases in the incidence of fetuses with gallbladder abnormalities such as small, bilobed, bifurcated, and missing gallbladders were observed at a dose of 900 nmol/kg/day. The rat and rabbit embryo-fetal development studies that included concurrent human insulin control groups indicated that insulin detemir and human insulin had similar effects regarding embryotoxicity and teratogenicity suggesting that the effects seen were the result of hypoglycemia resulting from insulin exposure in normal animals.

There are no published reports of adverse reactions, including hypoglycemia, in breastfed infants exposed to exogenous human insulin products, including insulin detemir, in breastmilk. There are no data on the effects of exogenous human insulin products, including insulin detemir, on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for LEVEMIR and any potential adverse effects on the breastfed infant from LEVEMIR or from the underlying maternal condition. 8.4 Pediatric Use The safety and effectiveness of LEVEMIR to improve glycemic control in pediatric patients with diabetes mellitus have been established. The use of LEVEMIR for this indication is supported by evidence from adequate and well-controlled trials (Studies D and I) in 694 pediatric patients aged 2 to 17 years with type 1 diabetes mellitus [see Clinical Studies ( 14.2 )] and from other studies in pediatric patients and adults with diabetes mellitus [see Clinical Pharmacology ( 12.3 ), Clinical Studies ( 14.3 )]. 8.5 Geriatric Use In clinical trials of LEVEMIR, 64 of 1624 patients (4%) in the type 1 diabetes trials and 309 of 1082 patients (29%) in the type 2 diabetes trials were 65 years or older. A total of 52 (7 type 1 and 45 type 2) patients (2%) were 75 years or older. No overall differences in safety or effectiveness were observed between these patients and younger patients, but small sample sizes limits conclusions. Greater sensitivity of some older individuals cannot be ruled out. In geriatric patients, the initial dosing, dosage increments, and maintenance dosage should be conservative to avoid hypoglycemia. Hypoglycemia may be difficult to recognize in the geriatric patients. 8.6 Renal Impairment No difference was observed in the pharmacokinetics of LEVEMIR between non-diabetic patients with kidney impairment and healthy volunteers. However, some studies with human insulin have shown increased circulating insulin concentrations in patients with kidney impairment. Careful glucose monitoring and dose adjustments of LEVEMIR, may be necessary in patients with kidney impairment [see Clinical Pharmacology ( 12.3 )] . 8.7 Hepatic Impairment Non-diabetic patients with severe hepatic impairment had lower systemic exposures to insulin detemir compared to healthy volunteers. However, some studies with human insulin have shown increased circulating insulin concentrations in patients with liver impairment. Careful glucose monitoring and dosage adjustments of LEVEMIR, may be necessary in patients with hepatic impairment [see Clinical Pharmacology ( 12.3 )] .
