LANTUS

Insulin glargine is a long-acting human insulin analog produced by recombinant DNA technology utilizing a non-pathogenic laboratory strain of Escherichia coli (K12). Insulin glargine differs from human insulin in that the amino acid asparagine at position A21 is replaced by glycine and two arginines are added to the C-terminus of the B-chain. Insulin glargine has a molecular weight of 6063 Da. LANTUS (insulin glargine) injection is a sterile, clear and colorless solution for subcutaneous use in a 10 mL multiple-dose vial or a 3 mL single-patient use prefilled pen (LANTUS Solostar). Prefilled Pen (LANTUS Solostar) and Vial: Each mL contains 100 units of insulin glargine and the inactive ingredients: glycerol 85% (20 mg), m-cresol (2.7 mg), zinc (30 mcg), and Water for Injection, USP. The vial also contains polysorbate 20 (20 mcg). The pH is adjusted by addition of aqueous solutions of hydrochloric acid and sodium hydroxide. LANTUS has a pH of approximately 4.

Individualize dosage based on metabolic needs, blood glucose monitoring, glycemic control, type of diabetes, and prior insulin use. ( 2.1 , 2.2 , 2.3 , 2.4 ) Administer subcutaneously into the abdominal area, thigh, or deltoid once daily at any time of day, but at the same time every day. ( 2.1 ) Do not dilute or mix with any other insulin or solution. ( 2.1 ) Rotate injection sites to reduce risk of lipodystrophy and localized cutaneous amyloidosis. ( 2.1 ) See Full Prescribing Information for the recommended starting dosage in patients with type 2 diabetes and how to change to LANTUS from other insulins ( 2.3 , 2.4 ) Closely monitor glucose when switching to LANTUS and during initial weeks thereafter. ( 2.4 ) 2.1 Important Administration Instructions Always check insulin labels before administration [see Warnings and Precautions (5.4) ] Visually inspect LANTUS vials and SoloStar prefilled pens for particulate matter and discoloration prior to administration. Only use if the solution is clear and colorless with no visible particles. Administer LANTUS subcutaneously into the abdominal area, thigh, or deltoid, and rotate injection sites within the same region from one injection to the next to reduce the risk of lipodystrophy and localized cutaneous amyloidosis. Do not inject into areas of lipodystrophy or localized cutaneous amyloidosis [see Warnings and Precautions (5.2) and Adverse Reactions (6) ] . During changes to a patient's insulin regimen, increase the frequency of blood glucose monitoring [see Warnings and Precautions (5.2) ] . Do not administer intravenously or via an insulin pump. Do not dilute or mix LANTUS with any other insulin or solution. The LANTUS SoloStar prefilled pen dials in 1-unit increments. Use LANTUS SoloStar prefilled pen with caution in patients with visual impairment who may rely on audible clicks to dial their dose. 2.2 General Dosing Instructions Administer LANTUS subcutaneously once daily at any time of day but at the same time every day. Individualize and adjust the dosage of LANTUS based on the patient's metabolic needs, blood glucose monitoring results and glycemic control goal. Dosage adjustments may be needed with changes in physical activity, changes in meal patterns (i.e., macronutrient content or timing of food intake), during acute illness, or changes in renal or hepatic function. Dosage adjustments should only be made under medical supervision with appropriate glucose monitoring [see Warnings and Precautions (5.2) ] . In patients with type 1 diabetes, LANTUS must be used concomitantly with short-acting insulin. 2.3 Initiation of LANTUS Therapy Recommended Starting Dosage in Patients with Type 1 Diabetes The recommended starting dosage of LANTUS in patients with type 1 diabetes is approximately one-third of the total daily insulin requirements. Use short-acting, premeal insulin to satisfy the remainder of the daily insulin requirements. Recommended Starting Dosage in Patients with Type 2 Diabetes The recommended starting dosage of LANTUS in patients with type 2 diabetes who are not currently treated with insulin is 0.2 units/kg or up to 10 units once daily. 2.4 Switching to LANTUS from Other Insulin Therapies Dosage adjustments are recommended to lower the risk of hypoglycemia when switching patients to LANTUS from other insulin therapies [see Warnings and Precautions (5.3) ]. When switching from: Once-daily TOUJEO (insulin glargine 300 units/mL) to once-daily LANTUS (100 units/mL), the recommended starting LANTUS dosage is 80% of the TOUJEO dosage that is being discontinued. Once-daily NPH insulin to once-daily LANTUS, the recommended starting LANTUS dosage is the same as the dosage of NPH that is being discontinued. Twice-daily NPH insulin to once-daily LANTUS, the recommended starting LANTUS dosage is 80% of the total NPH dosage that is being discontinued.

The data in Table 1 reflect the exposure of 2,327 patients with type 1 diabetes to LANTUS or NPH in Studies A, B, C, and D [see Clinical Studies (14.2) ] . The type 1 diabetes population had the following characteristics: Mean age was 39 years. Fifty-four percent were male, 97% were Caucasian, 22% were Black or African American and 33% were Hispanic. The mean BMI was 25.1 kg/m 2 . The data in Table 2 reflect the exposure of 1,563 patients with type 2 diabetes to LANTUS or NPH in Studies E, F, and G [see Clinical Studies (14.3) ] . The type 2 diabetes population had the following characteristics: Mean age was 59 years. Fifty-eight percent were male, 87% were Caucasian, 8% were Black or African American and 9% were Hispanic. The mean BMI was 29.2 kg/m 2 . The frequencies of adverse reactions during LANTUS clinical studies in patients with type 1 diabetes mellitus and type 2 diabetes mellitus are listed in the tables below (Tables 1, 2, 3, and 4). Table 1: Adverse Reactions Occurring ≥5% in Pooled Clinical Studies up to 28 Weeks Duration in Adults with Type 1 Diabetes LANTUS, % (n=1,257) NPH, % (n=1,070) Upper respiratory tract infection 22.4 23.1 Infection Body system not specified 9.4 10.3 Accidental injury 5.7 6.4 Headache 5.5 4.7 Table 2: Adverse Reactions Occurring ≥5% in Pooled Clinical Studies up to 1 Year Duration in Adults with Type 2 Diabetes LANTUS, % (n=849) NPH, % (n=714) Upper respiratory tract infection 11.4 13.3 Infection Body system not specified 10.4 11.6 Retinal vascular disorder 5.8 7.4 Table 3: Adverse Reactions Occurring ≥10% in a 5-Year Study of Adults with Type 2 Diabetes LANTUS, % (n=514) NPH, % (n=503) Upper respiratory tract infection 29.0 33.6 Edema peripheral 20.0 22.7 Hypertension 19.6 18.9 Influenza 18.7 19.5 Sinusitis 18.5 17.9 Cataract 18.1 15.9 Bronchitis 15.2 14.1 Arthralgia 14.2 16.1 Pain in extremity 13.0 13.1 Back pain 12.8 12.3 Cough 12.1 7.4 Urinary tract infection 10.7 10.1 Diarrhea 10.7 10.3 Depression 10.5 9.7 Headache 10.3 9.3 Table 4: Adverse Reactions Occurring ≥5% in a 28-Week Clinical Study in Pediatric Patients with Type 1 Diabetes LANTUS, % (n=174) NPH, % (n=175) Infection Body system not specified 13.8 17.7 Upper respiratory tract infection 13.8 16.0 Pharyngitis 7.5 8.6 Rhinitis 5.2 5.1 Severe Hypoglycemia Hypoglycemia was the most commonly observed adverse reaction in patients treated with LANTUS. Tables 5, 6, and 7 summarize the incidence of severe hypoglycemia in the LANTUS clinical studies. Severe symptomatic hypoglycemia was defined as an event with symptoms consistent with hypoglycemia requiring the assistance of another person and associated with either a blood glucose below 50 mg/dL (≤56 mg/dL in the 5-year study and ≤36 mg/dL in the ORIGIN study) or prompt recovery after oral carbohydrate, intravenous glucose, or glucagon administration. Percentages of LANTUS-treated adult patients who experienced severe symptomatic hypoglycemia in the LANTUS clinical studies [see Clinical Studies (14) ] were comparable to percentages of NPH-treated patients for all treatment regimens (see Tables 5 and 6 ). In the pediatric clinical study, pediatric patients with type 1 diabetes had a higher incidence of severe symptomatic hypoglycemia in the two treatment groups compared to the adult studies with type 1 diabetes.

Table 7: Severe Symptomatic Hypoglycemia in the ORIGIN Study ORIGIN Study Median duration of follow-up: 6.2 years LANTUS N=6231 Standard Care N=6273 Percent of patients 5.6 1.8 Peripheral Edema Some patients taking LANTUS have experienced sodium retention and edema, particularly if previously poor metabolic control was improved by intensified insulin therapy. Lipodystrophy Administration of insulin subcutaneously, including LANTUS, has resulted in lipoatrophy (depression in the skin) or lipohypertrophy (enlargement or thickening of tissue) in some patients [see Dosage and Administration (2.2) ] . Insulin Initiation and Intensification of Glucose Control 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. Weight Gain Weight gain has occurred with insulin including LANTUS and has been attributed to the anabolic effects of insulin and the decrease in glucosuria. Hypersensitivity Reactions Local Reactions Patients taking LANTUS experienced injection site reactions, including redness, pain, itching, urticaria, edema, and inflammation. In clinical studies in adult patients, there was a higher incidence of injection site pain in LANTUS-treated patients (2.7%) compared to NPH insulin-treated patients (0.7%). The reports of pain at the injection site did not result in discontinuation of therapy. Systemic Reactions Severe, life-threatening, generalized allergy, including anaphylaxis, generalized skin reactions, angioedema, bronchospasm, hypotension, and shock have occurred with insulin, including LANTUS and may be life threatening. 6.2 Immunogenicity As with all therapeutic proteins, there is potential for immunogenicity. All insulin products can elicit the formation of insulin antibodies. The presence of such insulin antibodies may increase or decrease the efficacy of insulin and may require adjustment of the insulin dose. In clinical studies of LANTUS, increases in titers of antibodies to insulin were observed in NPH insulin and LANTUS treatment groups with similar incidences. 6.3 Postmarketing Experience The following adverse reactions have been identified during postapproval use of LANTUS. 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 have been reported in which rapid-acting insulins and other insulins, have been accidentally administered instead of LANTUS 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.
