Insulin glargine

12.1 Mechanism of Action The primary activity of insulin, including insulin glargine, is regulation of glucose metabolism. Insulin and its analog lower blood glucose by stimulating peripheral glucose uptake, especially by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulin inhibits lipolysis and proteolysis, and enhances protein synthesis.

1 INDICATIONS AND USAGE BASAGLAR ® is indicated to improve glycemic control in adults and pediatric patients with type 1 diabetes mellitus and in adults with type 2 diabetes mellitus. BASAGLAR ® is a long-acting human insulin analog indicated to improve glycemic control in adults and pediatric patients with type 1 diabetes mellitus and in adults with type 2 diabetes mellitus. ( 1 ) Limitations of Use : Not recommended for treating diabetic ketoacidosis. ( 1 ) Limitations of Use BASAGLAR is not recommended for the treatment of diabetic ketoacidosis.

2 DOSAGE AND ADMINISTRATION Individualize dosage based on metabolic needs, blood glucose monitoring, glycemic control, type of diabetes, prior insulin use. ( 2.2 , 2.3 , 2.4 ) Administer subcutaneously once daily at any time of day, but at the same time every day. ( 2.2 ) Rotate injection sites into the abdominal area, thigh, or deltoid to reduce the risk of lipodystrophy and localized cutaneous amyloidosis. ( 2.1 ) Closely monitor glucose when converting to BASAGLAR and during initial weeks thereafter. ( 2.2 ) Do not dilute or mix with any other insulin or solution. ( 2.1 ) 2.1 Important Administration Instructions Always check insulin labels before administration [see Warnings and Precautions ( 5.4 )] . Visually inspect BASAGLAR prefilled pens for particulate matter and discoloration prior to administration. Only use if the solution is clear and colorless with no visible particles. Administer BASAGLAR 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 )] . Use BASAGLAR with caution in patients with visual impairment that may rely on audible clicks to dial their dose. Do not dilute or mix BASAGLAR with any other insulin or solution. Do not administer intravenously or via an insulin pump. 2.2 General Dosing Instructions In patients with type 1 diabetes, BASAGLAR must be used concomitantly with short-acting insulin. Inject BASAGLAR subcutaneously once daily at any time of day but at the same time every day. Individualize and adjust the dosage of BASAGLAR based on the individual'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 )] . The BASAGLAR prefilled pens each dials in 1 unit increments and delivers a maximum dose of 80 units per injection. 2.3 Initiation of BASAGLAR Therapy The recommended starting dose of BASAGLAR in patients with type 1 diabetes should be approximately one-third of the total daily insulin requirements. Short- or rapid-acting, pre-meal insulin should be used to satisfy the remainder of the daily insulin requirements. The recommended starting dose of BASAGLAR in patients with type 2 diabetes is 0.2 units/kg or up to 10 units once daily. 2.4 Changing to BASAGLAR from Other Insulin Therapies If changing patients from another insulin glargine product, 100 units/mL, to BASAGLAR, the dose of BASAGLAR should be the same as the other insulin glargine product, 100 units/mL. If changing patients from a once-daily insulin glargine product, 300 units/mL, to once-daily BASAGLAR, the recommended initial BASAGLAR dosage is 80% of the insulin glargine product, 300 units/mL [see Warnings and Precautions ( 5.2 )] . If changing from a treatment regimen with an intermediate- or long-acting insulin to a regimen with BASAGLAR, a change in the dose of the basal insulin may be required. If changing patients from twice-daily NPH insulin to once-daily BASAGLAR, the recommended initial BASAGLAR dosage is 80% of the total daily NPH dosage [see Warnings and Precautions ( 5.2 )] .

Two clinical trials with BASAGLAR were conducted: one in type 1 diabetes and one in type 2 diabetes. The type 1 diabetes population had the following characteristics: Mean age was 41 years and mean duration of diabetes was 16 years. 58% were male. 75% were Caucasian, 2% Black or African American and 4% American Indian or Alaskan native. 4% were Hispanic. At baseline, mean eGFR was 109 mL/min/1.73m 2 . 73.5 percent of patients had eGFR>90 mL/min/1.73m 2 . The mean BMI was approximately 26 kg/m 2 . HbA 1c at baseline was 7.8%. The data in Table 1 reflect exposure of 268 patients to BASAGLAR with a mean exposure duration of 49 weeks. The type 2 diabetes population had the following characteristics: Mean age was 59 years and mean duration of diabetes was 11 years. 50% were male. 78% were Caucasian, 8% Black or African American and 5% American Indian or Alaskan native. 28% were Hispanic. At baseline, mean eGFR was 109 mL/min/1.73m 2 . 67.5 percent of patients had eGFR>90 mL/min/1.73m 2 . The mean BMI was approximately 32 kg/m 2 . HbA 1c at baseline was 8.3%. The data in Table 2 reflect exposure of 376 patients to BASAGLAR with a mean exposure duration of 22 weeks. Common adverse reactions were defined as reactions occurring in ≥5% of the population studied. Common adverse reactions during clinical trials in patients with type 1 diabetes mellitus and type 2 diabetes mellitus (other than hypoglycemia) are listed in Table 1 and Table 2 , respectively.

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 BASAGLAR 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. 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 m
