Fiasp (Page 4 of 9)

8.2 Lactation

Risk Summary

There are no data on the presence of FIASP in human milk, the effects on the breastfed infant, or the effect on milk production. One small published study reported that exogenous insulin, including insulin aspart, was present in human milk. However, there is insufficient information to determine the effects of insulin aspart on the breastfed infant and no available information on the effects of insulin aspart on milk production. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for insulin, any potential adverse effects on the breastfed child from FIASP or insulin aspart or from the underlying maternal condition.

8.4 Pediatric Use

The safety and effectiveness of FIASP have been established to improve glycemic control in pediatric patients with diabetes mellitus. Use of FIASP for this indication is supported by evidence from an adequate and well-controlled study in 777 pediatric patients with type 1 diabetes mellitus aged 2 to 17 years, and from studies in adults with diabetes mellitus [ see Clinical Pharmacology (12.3) and Clinical Studies (14)].

Pediatric patients with type 1 diabetes treated with mealtime and postmeal FIASP reported a higher rate of blood glucose confirmed hypoglycemic episodes compared to patients treated with NovoLog; the imbalance was greater during the nocturnal period. Monitor blood glucose levels closely in pediatric patients [see Warnings and Precautions (5.3), Clinical Trial Experience (6.1)].

8.5 Geriatric Use

In the three controlled clinical studies, 192 of 1219 (16%) FIASP treated patients with type 1 or type 2 diabetes were ≥ 65 years of age and 24 of 1219 (2%) were ≥ 75 years of age. No overall differences in safety or effectiveness were observed between these elderly patients and younger adult patients.

Nevertheless, caution should be exercised when FIASP is administered to geriatric patients. In elderly patients with diabetes, the initial dosing, dose increments, and maintenance dosage should be conservative to avoid hypoglycemia [see Warnings and Precautions (5.3), Adverse Reactions (6.1) and Clinical Studies (14)].

Pharmacokinetic/pharmacodynamic study to assess the effect of age on the onset of FIASP action has been performed [see Clinical Pharmacology (12.3)].

8.6 Renal Impairment

Patients with renal impairment may be at increased risk of hypoglycemia and may require more frequent FIASP dose adjustment and more frequent blood glucose monitoring [see Warnings and Precautions (5.3) and Clinical Pharmacology (12.3)].

8.7 Hepatic Impairment

Patients with hepatic impairment may be at increased risk of hypoglycemia and may require more frequent FIASP dose adjustment and more frequent blood glucose monitoring [see Warnings and Precautions (5.3) and Clinical Pharmacology (12.3)].

10 OVERDOSAGE

Excess insulin administration may cause hypoglycemia and hypokalemia [see Warnings and Precautions (5.3, 5.5)]. Mild episodes of hypoglycemia usually can be treated with oral glucose. Adjustments in drug dosage, meal patterns, or exercise, may be needed. More severe episodes with coma, seizure or neurologic impairment may be treated with intramuscular/subcutaneous glucagon or concentrated intravenous glucose. Sustained carbohydrate intake and observation may be necessary because hypoglycemia may recur after apparent clinical recovery. Hypokalemia must be corrected appropriately.

11 DESCRIPTION

FIASP (insulin aspart injection) is a rapid-acting insulin analog for subcutaneous or intravenous administration used to lower blood glucose. Insulin aspart is homologous with regular human insulin with the exception of a single substitution of the amino acid proline by aspartic acid in position B28, and is produced by recombinant DNA technology utilizing Saccharomyces cerevisiae. Insulin aspart has the empirical formula C256 H381 N65 079 S6 and a molecular weight of 5825.8 daltons.

FIASP (insulin aspart injection) is an aqueous, sterile, clear and colorless solution. Each mL contains 100 units of insulin aspart and the inactive ingredients: arginine (as L-arginine hydrochloride), USP (3.48 mg); disodium phosphate dihydrate, USP (0.53 mg); glycerol, USP (3.3 mg); metacresol, USP (1.72 mg); niacinamide, USP (20.8 mg); phenol, USP (1.50 mg); zinc (as zinc acetate), USP (19.6 mcg) and water for injection, USP. FIASP has a pH of 7.1. Hydrochloric acid and/or sodium hydroxide may be added to adjust pH.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

The primary activity of FIASP is the regulation of glucose metabolism. Insulins, including insulin aspart, the active ingredient in FIASP, exert their specific action through binding to insulin receptors. Receptor-bound insulin lowers blood glucose by facilitating cellular uptake of glucose into skeletal muscle and adipose tissue and by inhibiting the output of glucose from the liver. Insulin inhibits lipolysis in the adipocyte, inhibits proteolysis, and enhances protein synthesis.

12.2 Pharmacodynamics

The time course of insulin action (i.e., glucose lowering) may vary considerably in different individuals or within the same individual. The average pharmacodynamic profile [i.e., glucose lowering effect measured as glucose infusion rate (GIR) in a euglycemic clamp study] for subcutaneous administration of 0.1, 0.2, and 0.4 unit/kg of FIASP in 46 patients with Type 1 diabetes is shown in Figure 2 and key characteristics of the timing of the effect are described in Table 6 below.

On average, the pharmacodynamic effects of FIASP, measured as area under the glucose infusion rate-time curve (AUCGIR ), was 697 mg/kg, 1406 mg/kg, and 2427 mg/kg following administration of 0.1, 0.2, and 0.4 unit/kg of FIASP.

The day-to-day variability in glucose-lowering-effect of FIASP within patients was ~18% for total glucose lowering (AUCGIR, 0-12h ) and ~19% for maximum glucose lowering effect (GIRmax ).
