ADMELOG is contraindicated:
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.
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. Repeated insulin injections into areas of lipodystrophy or localized cutaneous amyloidosis have been reported to result in hyperglycemia; and a sudden change in the injection site (to unaffected area) has been reported to result in hypoglycemia [see Adverse Reactions (6)].
Make any changes to a patient’s insulin regimen under close medical supervision with increased frequency of blood glucose monitoring. Advise patients who have repeatedly injected into areas of lipodystrophy or localized cutaneous amyloidosis to change the injection site to unaffected areas and closely monitor for hypoglycemia. For patients with type 2 diabetes, dosage adjustments of concomitant anti-diabetic products may be needed.
Hypoglycemia is the most common adverse reaction associated with insulins, including ADMELOG.
Severe hypoglycemia can cause seizures, may be life-threatening, or cause death. Hypoglycemia can impair concentration ability and reaction time; this may place an individual and others at risk in situations where these abilities are important (e.g., driving or operating other machinery).
Hypoglycemia can happen suddenly, and symptoms may differ in each individual and change over time in the same individual. Symptomatic awareness of hypoglycemia may be less pronounced in patients with longstanding diabetes, in patients with diabetic nerve disease, in patients using medications that block the sympathetic nervous system (e.g., beta-blockers) [see Drug Interactions (7)], or in patients who experience recurrent hypoglycemia.
The risk of hypoglycemia after an injection is related to the duration of action of the insulin and, in general, is highest when the glucose lowering effect of the insulin is maximal. As with all insulin preparations, the glucose lowering effect time course of ADMELOG may vary in different individuals or at different times in the same individual and depends on many conditions, including the area of injection as well as the injection site blood supply and temperature [see Clinical Pharmacology (12.2)]. Other factors which may increase the risk of hypoglycemia include changes in meal pattern (e.g., macronutrient content or timing of meals), changes in level of physical activity, or changes to coadministered medication [see Drug Interactions (7)]. Patients with renal or hepatic impairment may be at higher risk of hypoglycemia [see Use in Specific Populations (8.6, 8.7)].
Patients and caregivers must be educated to recognize and manage hypoglycemia. Self-monitoring of blood glucose plays an essential role in the prevention and management of hypoglycemia. In patients at higher risk for hypoglycemia and patients who have reduced symptomatic awareness of hypoglycemia, increased frequency of blood glucose monitoring is recommended.
Accidental mix-ups between basal insulin products and other insulins, particularly rapid-acting insulins, have been reported. To avoid medication errors between ADMELOG and other insulins, instruct patients to always check the insulin label before each injection.
Severe, life-threatening, generalized allergic reactions, including anaphylaxis, can occur with insulin products, including ADMELOG. If hypersensitivity reactions occur, discontinue ADMELOG; treat per standard of care and monitor until symptoms and signs resolve [see Adverse Reactions (6.1)]. ADMELOG is contraindicated in patients who have had hypersensitivity reactions to insulin lispro or any of the excipients [see Contraindications (4)].
All insulin products, including ADMELOG, cause a shift in potassium from the extracellular to intracellular space, possibly leading to hypokalemia. Untreated hypokalemia may cause respiratory paralysis, ventricular arrhythmia, and death. Monitor potassium levels in patients at risk for hypokalemia if indicated (e.g., patients using potassium-lowering medications, patients taking medications sensitive to serum potassium concentrations).
Thiazolidinediones (TZDs), which are peroxisome proliferator-activated receptor (PPAR)-gamma agonists, can cause dose-related fluid retention, particularly when used in combination with insulin. Fluid retention may lead to or exacerbate heart failure. Patients treated with insulin, including ADMELOG, and a PPAR-gamma agonist should be observed for signs and symptoms of heart failure. If heart failure develops, it should be managed according to current standards of care, and discontinuation or dose reduction of the PPAR-gamma agonist must be considered.
Malfunction of the insulin pump or insulin infusion set or insulin degradation can rapidly lead to hyperglycemia and ketoacidosis. Prompt identification and correction of the cause of hyperglycemia or ketosis is necessary. Interim subcutaneous injections with ADMELOG may be required. Patients using continuous subcutaneous insulin infusion pump therapy must be trained to administer insulin by injection and have alternate insulin therapy available in case of pump failure [see How Supplied/Storage and Handling (16.2) and Patient Counseling Information (17)].
The following adverse reactions are also discussed elsewhere:
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.
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 m² and 49% of patients had eGFR ≥90 mL/min/1.73 m². The mean BMI was 26 kg/m². 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 m² and 27% of patients had eGFR ≥90 mL/min/1.73 m². The mean BMI was 32 kg/m². The mean HbA1c at baseline was 7.99%.
Common adverse reactions were defined as reactions occurring in ≥5% of the population studied.
Common adverse reactions (other than hypoglycemia) during a clinical trial in patients with type 1 diabetes mellitus are listed in Table 1. In a 26-week clinical trial in patients with type 2 diabetes mellitus, no adverse reactions (other than hypoglycemia) occurring in ≥5% of ADMELOG-treated patients (n=253) were observed.
Table 1. Adverse Reactions Occurring in ≥5% of ADMELOG-Treated Patients with Type 1 Diabetes in a 52-Week Trial:
| ADMELOG + Insulin Glargine (100 units/mL), % (n=252) | |
|---|---|
| Nasopharyngitis | 13.1% |
| Upper respiratory tract infection | 6.0% |
Hypoglycemia is the most commonly observed adverse reaction in patients using insulin, including ADMELOG [see Warnings and Precautions (5.3)]. The rates of reported hypoglycemia depend on the definition of hypoglycemia used, diabetes type, insulin dose, intensity of glucose control, background therapies, and other intrinsic and extrinsic patient factors. For these reasons, comparing rates of hypoglycemia in clinical trials for ADMELOG with the incidence of hypoglycemia for other products may be misleading and also, may not be representative of hypoglycemia rates that will occur in clinical practice.
In the ADMELOG trials, severe hypoglycemia was defined as an event requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions. The incidence of severe hypoglycemia in patients receiving ADMELOG with type 1 diabetes mellitus and type 2 diabetes mellitus was 13.5% at 52 weeks and 2.4% at 26 weeks, respectively [see Clinical Studies (14)].
Intensification or rapid improvement in glucose control has been associated with a transitory, reversible ophthalmologic refraction disorder, worsening of diabetic retinopathy, and acute painful peripheral neuropathy. However, long-term glycemic control decreases the risk of diabetic retinopathy and neuropathy.
Long-term use of insulin, including ADMELOG, can cause lipodystrophy at the site of repeated insulin injections or infusion. Lipodystrophy includes lipohypertrophy (thickening of adipose tissue) and lipoatrophy (thinning of adipose tissue) and may affect insulin absorption. Rotate insulin injection or infusion sites within the same region to reduce the risk of lipodystrophy [see Dosage and Administration (2.2)].
Weight gain can occur with insulin therapy, including ADMELOG, and has been attributed to the anabolic effects of insulin and the decrease in glucosuria.
Insulin, including ADMELOG, may cause sodium retention and edema, particularly if previously poor metabolic control is improved by intensified insulin therapy.
In a randomized, open-label crossover study in adult patients with type 1 diabetes treated over two 4-week periods, the incidence of infusion set occlusions (defined as failure to correct hyperglycemia [plasma glucose ≥300 mg/dL] by insulin bolus via insulin pump) in ADMELOG-treated patients (n=25) was evaluated. Infusion-set occlusions were reported by 24% of patients.
In a randomized, 16-week, open-label, parallel design study of children and adolescents with type 1 diabetes, adverse event reports related to infusion-site reactions for another insulin lispro product, 100 units/mL, occurred in 21% of patients. The most frequently reported infusion site adverse events were infusion site erythema and infusion site reaction.
As with any insulin therapy, patients taking ADMELOG may experience redness, swelling, or itching at the site of the injection. These minor reactions usually resolve in a few days to a few weeks, but in some occasions may require discontinuation of ADMELOG. In some instances, these reactions may be related to factors other than insulin, such as irritants in a skin cleansing agent or poor injection technique.
Severe, life-threatening, generalized allergy, including anaphylaxis, may occur with any insulin, including ADMELOG. Generalized allergy to insulin may cause whole body rash (including pruritus), dyspnea, wheezing, hypotension, tachycardia, or diaphoresis.
Localized reactions and generalized myalgias have been reported with injected metacresol, which is an excipient in ADMELOG [see Contraindications (4)].
Consistent with the potentially immunogenic properties of protein and peptide pharmaceuticals, patients treated with ADMELOG may develop anti-insulin antibodies. The detection of antibody formation is highly dependent on the sensitivity and specificity of the assay and may be influenced by several factors such as assay methodology, sample handling, timing of sample collection, concomitant medication, and underlying disease. For these reasons, the incidence of antibodies to ADMELOG in the studies described below cannot be directly compared with the incidence of antibodies in other studies or to other products.
In a 52-week study of ADMELOG in type 1 diabetes patients, 49.4% were positive at baseline and 22.6% had treatment-emergent ADA (i.e., either new ADA, or increase in titer of at least 4-fold).
In a 26-week study of ADMELOG in type 2 diabetes patients, 26.4% were positive at baseline and 18.8% had treatment-emergent ADA (i.e., either new ADA, or increase in titer of at least 4-fold).
The following additional adverse reactions have been identified during postapproval use of another insulin lispro product, 100 units/mL. Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
Medication errors in which other insulins have been accidentally substituted for another insulin lispro product, 100 units/mL, have been identified during postapproval use [see Patient Counseling Information (17)].
Localized cutaneous amyloidosis at the injection site has occurred. Hyperglycemia has been reported with repeated insulin injections into areas of localized cutaneous amyloidosis; hypoglycemia has been reported with a sudden change to an unaffected injection site.
The risk of hypoglycemia associated with ADMELOG use may be increased when coadministered with antidiabetic agents, salicylates, sulfonamide antibiotics, monoamine oxidase inhibitors, fluoxetine, pramlintide, disopyramide, fibrates, pentoxifylline, ACE inhibitors, angiotensin II receptor blocking agents, and somatostatin analogs (e.g., octreotide). Dose adjustment and increased frequency of glucose monitoring may be required when ADMELOG is coadministered with these drugs.
The glucose lowering effect of ADMELOG may be decreased when coadministered with corticosteroids, isoniazid, niacin, estrogens, oral contraceptives, phenothiazines, danazol, diuretics, sympathomimetic agents (e.g., epinephrine, albuterol, terbutaline), somatropin, atypical antipsychotics, glucagon, protease inhibitors, and thyroid hormones. Dose adjustment and increased frequency of glucose monitoring may be required when ADMELOG is coadministered with these drugs.
The glucose lowering effect of ADMELOG may be increased or decreased when coadministered with beta-blockers, clonidine, lithium salts, and alcohol. Pentamidine may cause hypoglycemia, which may sometimes be followed by hyperglycemia. Dose adjustment and increased frequency of glucose monitoring may be required when ADMELOG is coadministered with these drugs.
The signs and symptoms of hypoglycemia [see Warnings and Precautions (5.3)] may be blunted when beta-blockers, clonidine, guanethidine, and reserpine are coadministered with ADMELOG.
The limited available data with ADMELOG in pregnant women are insufficient to inform a drug-associated risk of adverse developmental outcomes. 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.
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.
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. However, these studies cannot definitely establish or exclude the absence of any risk because of methodological limitations including small sample size, selection bias, confounding by unmeasured factors, and some lacking comparator groups.
In a combined fertility and embryo-fetal development study with another insulin lispro product, female rats were given subcutaneous insulin lispro injections of 5 and 20 units/kg/day (0.8 and 3 times the human subcutaneous dose of 1 unit/kg/day, based on units/body surface area, respectively) from 2 weeks prior to cohabitation through Gestation Day 19. There were no adverse effects on female fertility, implantation, or fetal viability and morphology. However, fetal growth retardation was observed at the 20 units/kg/day dose as indicated by decreased fetal weight and an increased incidence of fetal runts/litter.
In an embryo-fetal development study in pregnant rabbits with another insulin lispro product, insulin lispro doses of 0.1, 0.25, and 0.75 unit/kg/day (0.03, 0.08, and 0.24 times the human subcutaneous dose of 1 unit/kg/day, based on units/body surface area, respectively) were injected subcutaneously on Gestation Days 7 through 19. There were no adverse effects on fetal viability, weight, and morphology at any dose.
There is no information regarding the presence of insulin lispro in human milk, the effects on the breastfed infant, or the effects on milk production. Endogenous insulin is present in human milk.
The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for ADMELOG and any potential adverse effects on the breastfed child from ADMELOG or from the underlying maternal condition.
The safety and effectiveness of ADMELOG have been established in pediatric patients with type 1 diabetes mellitus who are 3 years of age and older. Use of ADMELOG in these age groups is supported by evidence from adequate and well-controlled studies of ADMELOG and another insulin lispro product, 100 units/ml, in adults with additional data from adequate and well-controlled studies of pediatric patients using another insulin lispro product, 100 units/ml [see Clinical Studies (14)].
The safety and effectiveness of ADMELOG have not been established in pediatric patients younger than 3 years of age with type 1 diabetes mellitus or in pediatric patients with type 2 diabetes mellitus.
The dosage of ADMELOG must be individualized in pediatric patients based on metabolic needs and results of frequent monitoring of blood glucose.
Of the total number of subjects (n=2,834) in eight clinical studies of another insulin lispro product, 100 units/mL, 12% (n=338) were 65 years of age or over. The majority of these had type 2 diabetes. HbA1c values and hypoglycemia rates did not differ by age.
Of the total number of subjects (n=1,011) in clinical studies of patients treated with ADMELOG or another insulin lispro product, 100 units/mL, 26.5% (n=268) were 65 years of age or over. The majority of these had type 2 diabetes. HbA1c values and hypoglycemia rates did not differ by age.
Pharmacokinetic/pharmacodynamic studies to assess the effect of age on the onset of ADMELOG action have not been performed.
Patients with renal impairment may be at increased risk of hypoglycemia and may require more frequent ADMELOG dose adjustment and more frequent blood glucose monitoring [see Clinical Pharmacology (12.3)].
Patients with hepatic impairment may be at increased risk of hypoglycemia and may require more frequent ADMELOG dose adjustment and more frequent blood glucose monitoring [see Clinical Pharmacology (12.3)].
