What it is used to treat

is indicated to improve glycemic control in adult and pediatric patients with diabetes mellitus. ADMELOG is a rapid-acting human insulin analog indicated to improve glycemic control in adult and pediatric patients with diabetes mellitus. ( 1 )

About this medicine

Insulin lispro is a rapid-acting human insulin analog produced by recombinant DNA technology utilizing a non-pathogenic laboratory strain of Escherichia coli . Insulin lispro differs from human insulin in that the amino acid proline at position B28 is replaced by lysine and the lysine in position B29 is replaced by proline. Insulin lispro has a molecular weight of 5808 Da, identical to that of human insulin. ADMELOG (insulin lispro) injection is a sterile, aqueous, clear, and colorless solution for subcutaneous or intravenous use. Each mL of ADMELOG contains 100 units of insulin lispro, and the inactive ingredients: dibasic sodium phosphate (1.88 mg), glycerin (16 mg), metacresol (3.15 mg), zinc oxide (content adjusted to provide 0.0197 mg zinc ion), and Water for Injection, USP. Insulin lispro has a pH of 7.0 to 7.8. The pH is adjusted by addition of aqueous solutions of hydrochloric acid and/or sodium hydroxide. ADMELOG is latex free.

How it works

12.1 Mechanism of Action Regulation of glucose metabolism is the primary activity of insulins and insulin analogs, including insulin lispro products. Insulins lower blood glucose by stimulating peripheral glucose uptake by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulins inhibit lipolysis and proteolysis and enhance protein synthesis.

Who should not take it

is contraindicated: during episodes of hypoglycemia [see Warnings and Precautions (5.3) ] . in patients who are hypersensitive to insulin lispro or to any of the excipients in ADMELOG [see Warnings and Precautions (5.5) ]. Do not use during episodes of hypoglycemia. ( 4 ) Do not use in patients with hypersensitivity to insulin lispro or any of the excipients in ADMELOG. ( 4 )

Warnings and cautions

Never share an ADMELOG SoloStar disposable prefilled pen or syringe between patients, even if the needle is changed. ( 5.1 ) Hyperglycemia or Hypoglycemia with Changes in Insulin Regimen: Make changes to a patient's insulin regimen (e.g., insulin strength, manufacturer, type, injection site or method of administration) under close medical supervision with increased frequency of blood glucose monitoring. ( 5.2 ) Hypoglycemia: May be life-threatening. Monitor blood glucose and increase monitoring frequency with changes to insulin dosage, use of glucose lowering medications, meal pattern, physical activity; in patients with renal or hepatic impairment; and in patients with hypoglycemia unawareness. ( 5.3 , 6 , 7 , 8.6 , 8.7 ) Hypoglycemia Due to Medication Errors: Accidental mix-ups between insulin products can occur. Instruct patients to check insulin labels before injection. ( 5.4 ) Hypersensitivity Reactions: May be life-threatening. Discontinue ADMELOG, monitor and treat if indicated. ( 5.5 ) Hypokalemia: May be life-threatening. Monitor potassium levels in patients at risk of hypokalemia and treat if indicated. ( 5.6 ) Fluid Retention and Heart Failure with Concomitant Use of Thiazolidinediones (TZDs): Observe for signs and symptoms of heart failure; consider dosage reduction or discontinuation if heart failure occurs. ( 5.7 ) Hyperglycemia and Ketoacidosis Due to Insulin Pump Device Malfunction: Monitor glucose and administer ADMELOG by subcutaneous injection if pump malfunction occurs. ( 5.8 ) 5.1 Never Share an ADMELOG SoloStar Pen or Syringe Between Patients ADMELOG SoloStar prefilled pen must never be shared between patients, even if the needle is changed. Patients using ADMELOG vials must never share needles or syringes with another person. Sharing poses a risk for transmission of blood-borne pathogens. 5.2 Hyperglycemia or Hypoglycemia with Changes in Insulin Regimen Changes in an insulin regimen (e.g., insulin strength, manufacturer, type, injection site or method of administration) may affect glycemic control and predispose to hypoglycemia [see Warnings and Precautions (5.3) ] or hyperglycemia.

Reported side effects

The following adverse reactions are discussed elsewhere: Hypoglycemia [see Warnings and Precautions (5.3) ] Hypoglycemia Due to Medication Errors [see Warnings and Precautions (5.4) ] Hypersensitivity Reactions [see Warnings and Precautions (5.5) ] Hypokalemia [see Warnings and Precautions (5.6) ] Adverse reactions associated with ADMELOG include hypoglycemia, allergic reactions, injection site reactions, lipodystrophy, pruritus, and rash. ( 6.1 ) To report SUSPECTED ADVERSE REACTIONS, contact sanofi-aventis at 1-800-633-1610 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch. 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Adverse Reactions with Subcutaneous Injections of ADMELOG Two clinical trials with ADMELOG were conducted: one in patients with type 1 diabetes and one in patients with type 2 diabetes [see Clinical Studies (14) ] . The data in Table 1 reflect the exposure of 252 patients with type 1 diabetes to ADMELOG with mean exposure duration of 49 weeks. The type 1 diabetes population had the following characteristics: Mean age was 43 years and mean duration of diabetes was 20 years. Fifty-nine percent were male, 80% were White, 6% were Black or African American and 7% were Hispanic. At baseline, the mean eGFR was 90 mL/min/1.73 m 2 and 49% of patients had eGFR ≥90 mL/min/1.73 m 2 . The mean BMI was 26 kg/m 2 . The mean HbA1c at baseline was 8.07%. Two hundred fifty-three patients with type 2 diabetes were exposed to ADMELOG with mean exposure duration of 25 weeks. The type 2 diabetes population had the following characteristics: Mean age was 62 years and mean duration of diabetes was 17 years. Fifty-four percent were male, 90% were White, 6% were Black or African American and 17% were Hispanic. At baseline, the mean eGFR was 77 mL/min/1.73 m 2 and 27% of patients had eGFR ≥90 mL/min/1.73 m 2 . The mean BMI was 32 kg/m 2 . The mean HbA1c at baseline was 7.99%. […]

Use in specific groups

8.1 Pregnancy Risk Summary Published studies with another insulin lispro product used during pregnancy have not reported an association between insulin lispro and the induction of major birth defects, miscarriage, or adverse maternal or fetal outcomes [see Data ] . There are risks to the mother and fetus associated with poorly controlled diabetes in pregnancy [see Clinical Considerations ] . Pregnant rats and rabbits were exposed to another insulin lispro product in animal reproduction studies during organogenesis. Fetal growth retardation was observed in offspring of rats exposed to insulin lispro at a dose approximately 3 times the human subcutaneous dose of 1.0 unit/kg/day. No adverse effects on embryo-fetal development were observed in offspring of rabbits exposed to insulin lispro at doses up to approximately 0.24 times the human subcutaneous dose of 1.0 unit/kg/day [see Data ] . The estimated background risk of major birth defects is 6%–10% in women with pregestational diabetes with a HbA1c >7% and has been reported to be as high as 20%–25% in women with a HbA1c >10%. The estimated background risk of miscarriage for the indicated population is unknown. 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. Clinical Considerations Disease-associated maternal and/or embryo-fetal risk 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 Published data from retrospective studies and meta-analyses do not report an association with another insulin lispro product and major birth defects, miscarriage, or adverse maternal or fetal outcomes when insulin lispro is used during pregnancy.

If too much is taken

Excess insulin administration may cause hypoglycemia and hypokalemia. 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 a glucagon product for emergency use 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.
