Insulin Degludec

1 INDICATIONS AND USAGE TRESIBA is indicated to improve glycemic control in patients 1 year of age and older with diabetes mellitus. Limitations of Use • Not recommended for the treatment of diabetic ketoacidosis. TRESIBA is a long-acting human insulin analog indicated to improve glycemic control in patients 1 year of age and older with diabetes mellitus ( 1 ). Limitations of Use: • Not recommended for the treatment of diabetic ketoacidosis.

2 DOSAGE AND ADMINISTRATION • See Full Prescribing Information for important administration instructions ( 2.1 ). • Inject TRESIBA subcutaneously into the thigh, upper arm, or abdomen ( 2.1 ). • Rotate injection sites to reduce risk of lipodystrophy and localized cutaneous amyloidosis ( 2.1 ). • For pediatric patients requiring less than 5 units of TRESIBA each day, use a TRESIBA U-100 vial ( 2.1 ). • In adults, inject subcutaneously once daily at any time of day ( 2.2 ). • In pediatric patients inject subcutaneously once daily at the same time every day ( 2.2 ). • Individualize dose based on type of diabetes, metabolic needs, blood glucose monitoring results and glycemic control goal ( 2.2 ). • The recommended days between dose increases are 3 to 4 days ( 2.2 ). • See Full Prescribing Information for recommended starting dose in insulin naïve patients and patients already on insulin therapy ( 2.3 , 2.4 ). 2.1 Important Administration Instructions • Always check insulin labels before administration [see Warnings and Precautions ( 5.4 ) ] . • Inspect visually for particulate matter and discoloration. Only use TRESIBA if the solution appears clear and colorless. • Inject TRESIBA subcutaneously into the thigh, upper arm, or abdomen. • 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 ), Adverse Reactions ( 6.1 , 6.3 )]. • During changes to a patient’s insulin regimen, increase the frequency of blood glucose monitoring [see Warnings and Precautions ( 5.2 )]. • For pediatric patients requiring less than 5 units of TRESIBA each day, use the TRESIBA U-100 vial. • DO NOT administer TRESIBA intravenously or in an insulin infusion pump. • DO NOT dilute or mix TRESIBA with any other insulin or solution. • DO NOT transfer TRESIBA from the TRESIBA FlexTouch pen into a syringe for administration [see Warnings and Precautions ( 5.4 )]. • Use TRESIBA FlexTouch pens with caution in patients with visual impairment that may rely on audible clicks to dial their dose. 2.2 General Dosing Instructions • TRESIBA is available in 2 concentrations (U-100 and U-200): o TRESIBA U-100 is available, as a single-patient use FlexTouch pen and multiple-dose vial. ▪ The FlexTouch pen delivers doses in 1 unit increments and can deliver up to 80 units in a single injection. o TRESIBA U-200 is available as a single-patient-use FlexTouch pen. ▪ The FlexTouch pen delivers doses in 2 unit increments and can deliver up to 160 units in a single injection. • DO NOT perform dose conversion when using the TRESIBA U-100 or U-200 FlexTouch pens. The dose window shows the number of insulin units to be delivered and no conversion is needed. • In adults, inject TRESIBA subcutaneously once-daily at any time of day. • In pediatric patients inject TRESIBA subcutaneously once-daily at the same time every day. • Individualize and titrate the dose of TRESIBA based on the patient’s metabolic needs, blood glucose monitoring results, and glycemic control goal . • The recommended days between dose increases are 3 to 4 days. • Dose adjustments may be needed with changes in physical activity, changes in meal patterns (i.e., macronutrient content or timing of food intake), changes in renal or hepatic function or during acute illness to minimize the risk of hypoglycemia or hyperglycemia [see Warnings and Precautions ( 5.3 )] . • For adult patients, instruct patients who miss a dose of TRESIBA to inject their daily dose during waking hours upon discovering the missed dose. Instruct patients to ensure that at least 8 hours have elapsed between consecutive TRESIBA injections. • For pediatric patients, instruct patients who miss a dose of TRESIBA to contact their healthcare provider for guidance and to monitor blood glucose levels more frequently until the next scheduled TRESIBA dose. • In patients with type 1 diabetes, TRESIBA must be used concomitantly with short-acting insulin. 2.3 Starting Dose in Insulin Naïve Patients Recommended Starting Dosage in Patients with Type 1 Diabetes Mellitus: The recommended starting dose of TRESIBA in insulin naïve patients with type 1 diabetes is approximately one-third to one-half of the total daily insulin dose. The remainder of the total daily insulin dose should be administered as a short-acting insulin and divided between each daily meal. As a general rule, 0.2 to 0.4 units of insulin per kilogram of body weight can be used to calculate the initial total daily insulin dose in insulin naïve patients with type 1 diabetes. Recommended Starting Dosage in Patients with Type 2 Diabetes Mellitus: The recommended starting dose of TRESIBA in insulin naïve patients with type 2 diabetes mellitus is 10 units once daily. 2.4 Switching to TRESIBA from Other Insulin Therapies Dosage adjustments are recommended to lower the risk of hypoglycemia when switching patients to Insulin Degludec from another insulin therapy [see Warnings and Precautions ( 5.3 )]. Adults with Type 1 or Type 2 Diabetes Mellitus: Start TRESIBA at the same unit dose as the total daily long or intermediate-acting insulin unit dose. Pediatric Patients 1 Year of Age and Older with Type 1 or Type 2 Diabetes Mellitus: Start TRESIBA at 80% of the total daily long or intermediate-acting insulin unit dose to minimize the risk of hypoglycemia [see Warnings and Precautions ( 5.2 )].

6 ADVERSE REACTIONS The following adverse reactions are also 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 commonly associated with TRESIBA are: • hypoglycemia, allergic reactions, injection site reactions, lipodystrophy, pruritus, rash, edema and weight gain ( 6.1 ).

The safety of TRESIBA in subjects with type 1 diabetes or type 2 diabetes was evaluated in nine trials of 6-12 month duration in adults and in one trial of 12-month duration in pediatric patients 1 year of age and older with type 1 diabetes. The cardiovascular safety of TRESIBA was evaluated in one double-blinded, event-driven trial of 2-year median duration in patients with type 2 diabetes at high risk of cardiovascular events [see Clinical Studies ( 14 )]. The data in Table 1 reflect the exposure of 1102 adults with type 1 diabetes to TRESIBA with a mean exposure duration to TRESIBA of 34 weeks in three open-label trials; Study A, B and C [see Clinical Studies (14.1)] . The mean age was 43 years and 1% were older than 75 years. Fifty-seven percent were male, 81% were White, 2% were Black or African American and 4% were Hispanic. The mean body mass index (BMI) was 26 kg/m 2 . The mean duration of diabetes was 18 years and the mean HbA 1c at baseline was 7.8%. A history of neuropathy, ophthalmopathy, nephropathy and cardiovascular disease at baseline was reported in 11%, 16%, 7% and 0.5% respectively. The mean eGFR at baseline was 87 mL/min/1.73 m 2 and 7% of the patients had an eGFR less than 60 mL/min/1.73 m 2 . The data in Table 2 reflect the exposure of 2713 adults with type 2 diabetes to TRESIBA with a mean exposure duration to TRESIBA of 36 weeks in six open-label trials; Study D, E, F, G, H and I [see Clinical Studies (14.3)] . The mean age was 58 years and 3% were older than 75 years. Fifty-eight percent were male, 71% were White, 7% were Black or African American and 13% were Hispanic. The mean BMI was 30 kg/m 2 . The mean duration of diabetes was 11 years and the mean HbA 1c at baseline was 8.3%. A history of neuropathy, ophthalmopathy, nephropathy and cardiovascular disease at baseline was reported for 14%, 10%, 6% and 0.6% of participants respectively. At baseline, the mean eGFR was 83 mL/min/1.73 m 2 and 9% had an eGFR less than 60 mL/min/1.73 m 2 . Common adverse reactions (excluding hypoglycemia) occurring in TRESIBA treated subjects during clinical trials in adult patients with type 1 diabetes mellitus and adults with type 2 diabetes mellitus are listed in Table 1 and Table 2, respectively. Common adverse reactions were defined as reactions occurring in ≥5% of the population studied. Hypoglycemia is not shown in these tables but discussed in a dedicated subsection below. 174 pediatric patients 1 year of age and older with type 1 diabetes were exposed to TRESIBA with a mean exposure to TRESIBA of 48 weeks. The mean age was 10 years: 25% were ages 1-5 years, 40% were ages 6-11 years, and 35% were ages 12-17 years. 55% were male, 78% were White, 3% were Black or African American and 4% were Hispanic. The mean body mass index (BMI) was 18.7 kg/m 2 . The mean duration of diabetes was 3.9 years and the mean HbA 1c at baseline was 8.2%. Common adverse reactions in TRESIBA treated pediatric patients with type 1 diabetes mellitus were similar to the adverse reactions listed in Table 1. Table 1: Adverse Reactions Occurring in ≥5% of TRESIBA-Treated Adult Patients with Type 1 Diabetes Mellitus Adverse Reaction TRESIBA (N=1,102) Nasopharyngitis 23.9 % Upper respiratory tract infection 11.9 % Headache 11.8 % Sinusitis 5.1 % Gastroenteritis 5.1 % Table 2: Adverse Reactions Occurring in ≥5% of TRESIBA-Treated Adult Patients with Type 2 Diabetes Mellitus Adverse Reaction TRESIBA (N=2,713) Nasopharyngitis 12.9 % Headache 8.8 % Upper respiratory tract infection 8.4 % Diarrhea 6.3 % Hypoglycemia Hypoglycemia was the most commonly observed adverse reaction in patients treated with TRESIBA. 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 TRESIBA 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 open-label adult clinical trials of patients with type 1 and type 2 diabetes, and in the open-label pediatric clinical trial of patients with type 1 diabetes, percentages of adult and pediatric patients with type 1 diabetes randomized to TRESIBA who experienced at least one episode of hypoglycemia in clinical trials [see Clinical Studies ( 14 )] and adults with type 2 diabetes are shown in Tables 3 and 4, respectively. Severe hypoglycemia in the open-label trials with adult patients was defined as an episode requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions. Severe hypoglycemia in the pediatric trial was defined as an altered mental status where the child could not assist in his own care, was semiconscious or unconscious, or in a coma ± convulsions and may require parenteral therapy (glucagon or intravenous glucose). A hypoglycemia episode was defined as a severe hypoglycemia episode or an episode where a laboratory or a self-measured glucose calibrated to plasma was less than 56 mg/dL or where a whole blood glucose was less than 50 mg/dL (i.e., with or without the presence of hypoglycemic symptoms). Table 3: Percent (%) of Type 1 Diabetes Patients Experiencing at Least One Episode of Severe Hypoglycemia or Hypoglycemia § on TRESIBA in Open-Label Adult and Pediatric Clinical Trials Study A Adults + insulin aspart 52 weeks Study B Adults + insulin aspart 26 weeks Study C Adults + insulin aspart 26 weeks Study J Pediatrics + insulin aspart 52 weeks TRESIBA (N=472) TRESIBA (N=301) TRESIBA at the same time each day (N=165) TRESIBA at alternating times (N=164) TRESIBA (N=174) Severe hypoglycemia* Percent of patients 12.3% 10.6% 12.7% 10.4% 17.8% Hypoglycemia § Percent of patients 95.6% 93.0% 99.4% 93.9% 98.3% * Severe hypoglycemia in pediatric patients: an episode with altered mental status, where the child could not assist in his own care, was semiconscious or unconscious, or in a coma ± convulsions and may require parenteral therapy (glucagon or intravenous glucose). § Hypoglycemia : a severe hypoglycemia episode or an episode where a laboratory or a self-measured glucose calibrated to plasma was less than 56 mg/dL or where a whole blood glucose was less than 50 mg/dL (i.e., with or without the presence of hypoglycemic symptoms).

Hypersensitivity Reactions Severe, life-threatening, generalized allergy, including anaphylaxis, generalized skin reactions, angioedema, bronchospasm, hypotension, and shock have occurred with insulin, including TRESIBA and may be life threatening. Hypersensitivity (manifested with swelling of tongue and lips, diarrhea, nausea, tiredness, and itching) and urticaria were reported in 0.9% of patients treated with TRESIBA. Lipodystrophy Long-term use of insulin, including TRESIBA, can cause lipodystrophy at the site of repeated insulin injections. Lipodystrophy includes lipohypertrophy (thickening of adipose tissue) and lipoatrophy (thinning of adipose tissue) and may affect insulin absorption [see Dosage and Administration ( 2.1 )] . In the clinical program, lipodystrophy, lipohypertrophy, or lipoatrophy was reported in 0.3% of patients treated with TRESIBA. Injection Site Reactions Patients taking TRESIBA may experience injection site reactions, including injection site hematoma, pain, hemorrhage, erythema, nodules, swelling, discoloration, pruritus, warmth, and injection site mass. In the clinical program, injection site reactions occurred in 3.8% of patients treated with TRESIBA. Weight Gain Weight gain can occur with insulin therapy, including TRESIBA, and has been attributed to the anabolic effects of insulin. In the clinical program after 52 weeks of treatment, patients with type 1 diabetes treated with TRESIBA gained an average of 1.8 kg and patients with type 2 diabetes treated with TRESIBA gained an average of 3.0 kg. Peripheral Edema TRESIBA, may cause sodium retention and edema. In the clinical program, peripheral edema occurred in 0.9% of patients with type 1 diabetes mellitus and 3.0% of patients with type 2 diabetes mellitus treated with TRESIBA. 6.2 Immunogenicity As with all therapeutic proteins, insulin administration may cause anti-insulin antibodies to form. 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, comparison of the incidence of antibodies to TRESIBA with the incidence of antibodies in other studies or to other products may be misleading. In a 52-week trial of adult insulin-experienced type 1 diabetes patients, 68.9% of patients who received TRESIBA were positive at baseline for anti-insulin degludec antibodies and 12.3% of the patients developed anti-insulin degludec antibodies at least once during the trial. In a 52-week trial of pediatric insulin-experienced type 1 diabetes patients, 84.1% of patients who received TRESIBA were positive at baseline for anti-insulin degludec antibodies and 5.8% of patients developed anti-insulin degludec antibodies at least once during the trial. In a 52-week trial of adult insulin-naïve type 2 diabetes patients, 1.7% of patients who received TRESIBA were positive at baseline for anti-insulin degludec antibodies and 6.2% of patients developed anti-insulin degludec antibodies at least once during the trial. In these trials, between 96.7% and 99.7% of patients who were positive for anti-insulin degludec antibodies were also positive for anti-human insulin antibodies. 6.3 Postmarketing Experience The following additional adverse reactions have been identified during post-approval use of TRESIBA. 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. 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.

12.3 Pharmacokinetics Absorption In patients with type 1 diabetes, after 8 days of once daily subcutaneous dosing with 0.4 units/kg of TRESIBA, maximum insulin degludec concentrations of 4472 pmol/L were attained at a median of 9 hours (t max ). After the first dose of TRESIBA, median onset of appearance was around one hour. Total insulin degludec concentration (i.e., exposure) increased in a dose proportional manner after subcutaneous administration of 0.4 units/kg to 0.8 units/kg TRESIBA. Total and maximum insulin degludec exposure at steady state are comparable between TRESIBA U-100 and TRESIBA U-200 when each is administered at the same units/kg dose. Insulin degludec concentration reached steady state levels after 3-4 days of TRESIBA administration [see Dosage and Administration ( 2.2 )] . Distribution The affinity of insulin degludec to serum albumin corresponds to a plasma protein binding of >99% in human plasma. The results of the in vitro protein binding studies demonstrate that there is no clinically relevant interaction between insulin degludec and other protein bound drugs. Elimination The half-life after subcutaneous administration is determined primarily by the rate of absorption from the subcutaneous tissue. On average, the half-life at steady state is approximately 25 hours independent of dose. Degradation of TRESIBA is similar to that of insulin human; all metabolites formed are inactive. The mean apparent clearance of insulin degludec is 0.03 L/kg (2.1 L/h in 70 kg patient) after single subcutaneous dose of 0.4 units/kg. Specific Populations Pediatrics- Population pharmacokinetic analysis was conducted for TRESIBA using data from 199 pediatric subjects (1 to <18 years of age) with type 1 diabetes. Body weight was a significant covariate affecting the clearance of TRESIBA. After adjusting for body weight, the total exposure of TRESIBA at steady state was independent of age. Geriatrics - Pharmacokinetic and pharmacodynamic response of TRESIBA was compared in 13 younger adult (18−35 years) and 14 geriatric (≥65 years) subjects with type 1 diabetes following two 6-day periods of once-daily subcutaneous dosing with 0.4 units/kg dose of TRESIBA or insulin glargine. On average, the pharmacokinetic and pharmacodynamic properties of TRESIBA at steady-state were similar in younger adult and geriatric subjects, albeit with greater between subject variability among the geriatric subjects. Gender - The effect of gender on the pharmacokinetics of TRESIBA was examined in an across-trial analysis of the pharmacokinetic and pharmacodynamic studies conducted using unit/kg doses of TRESIBA. Overall, there were no clinically relevant differences in the pharmacokinetic properties of insulin degludec between female and male subjects. Obesity- The effect of BMI on the pharmacokinetics of TRESIBA was explored in a cross-trial analysis of pharmacokinetic and pharmacodynamic studies conducted using unit/kg doses of TRESIBA. For subjects with type 1 diabetes, no relationship between exposure of TRESIBA and BMI was observed. For subjects with type 1 and type 2 diabetes a trend for decrease in glucose-lowering effect of TRESIBA with increasing BMI was observed. Race and Ethnicity - TRESIBA has been studied in a pharmacokinetic and pharmacodynamic study in Black or African American subjects not of Hispanic or Latino origin (N=18), White subjects of Hispanic or Latino origin (N=22) and White subjects not of Hispanic or Latino origin (N=23) with type 2 diabetes mellitus conducted using unit/kg doses of TRESIBA. There were no statistically significant differences in the pharmacokinetic and pharmacodynamic properties of TRESIBA between the racial and ethnic groups investigated. Pregnancy- The effect of pregnancy on the pharmacokinetics and pharmacodynamics of TRESIBA has not been studied [see Use in Specific Populations ( 8.1 )] . Renal Impairment - TRESIBA pharmacokinetics was studied in 32 subjects (N=4-8/group) with normal or impaired renal function/end-stage renal disease following administration of a single subcutaneous dose (0.4 units/kg) of TRESIBA. Renal function was defined using creatinine clearance (Clcr) as follows: ≥90 mL/min (normal), 60-89 mL/min (mild), 30-59 mL/min (moderate) and <30 mL/min (severe). Subjects requiring dialysis were classified as having end-stage renal disease (ESRD). Total (AUC IDeg,0-120h,SD ) and peak exposure of TRESIBA were on average about 10-25% and 13-27% higher, respectively in subjects with mild to severe renal impairment except subjects with ESRD who showed similar exposure as compared to subjects with normal renal function. No systematic trend was noted for this increase in exposure across different renal impairment subgroups. Hemodialysis did not affect clearance of TRESIBA (CL/F IDeg,SD ) in subjects with ESRD [see Use in Specific Populations ( 8.6 )] . Hepatic Impairment - TRESIBA has been studied in a pharmacokinetic study in 24 subjects (N=6/group) with normal or impaired hepatic function (mild, moderate, and severe hepatic impairment) following administration of a single subcutaneous dose (0.4 units/kg) of TRESIBA. Hepatic function was defined using Child-Pugh Scores ranging from 5 (mild hepatic impairment) to 15 (severe hepatic impairment). No differences in the pharmacokinetics of TRESIBA were identified between healthy subjects and subjects with hepatic impairment [see Use in Specific Populations ( 8.7 )] .
