Tresiba insulin degludec 100 U/mL Injection, Solution

5 WARNINGS AND PRECAUTIONS • Never share a TRESIBA FlexTouch pen, insulin syringe, or needle 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. Increase monitoring with changes to: insulin dosage, concomitant drugs, meal pattern, physical activity; and in patients with renal impairment or hepatic impairment or hypoglycemia unawareness ( 5.3 , 5.4 , 6.1 ). • Hypoglycemia due to medication errors: Accidental mix-ups between insulin products can occur.

Instruct patients to check insulin labels before injection. DO NOT transfer TRESIBA from the TRESIBA pen into a syringe for administration as overdosage and severe hypoglycemia can result ( 5.4 ). • Hypersensitivity reactions : Severe, life-threatening, generalized allergy, including anaphylaxis, can occur. Discontinue TRESIBA, monitor and treat if indicated ( 5.5 ). • Hypokalemia: May be life-threatening.

Monitor potassium levels in patients at risk for 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 ).

5.1Never Share a TRESIBA FlexTouch Pen, Needle, or Insulin Syringe Between Patients TRESIBA FlexTouch disposable prefilled pens should never be shared between patients, even if the needle is changed. Patients using TRESIBA vials should never share needles or syringes with another person. Sharing poses a risk for transmission of blood-borne pathogens.

5.2Hyperglycemia 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. 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 an unaffected area) has been reported to result in hypoglycemia [see Adverse Reactions ( 6.1 , 6.3 )].

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, adjustments in concomitant anti-diabetic treatment may be needed [see Dosage and Administration ( 2.4 )].

5.3Hypoglycemia Hypoglycemia is the most common adverse reaction of insulin, including TRESIBA [see Adverse Reactions ( 6.1 )]. Severe hypoglycemia can cause seizures, may be life-threatening or cause death. Hypoglycemia can impair concentration ability and reaction time; this may place the patient and others at risk in situations where these abilities are important (e.g., driving or operating other machinery).

TRESIBA, or any insulin, should not be used during episodes of hypoglycemia [see Contraindications ( 4 )]. Hypoglycemia can happen suddenly and symptoms may differ in each patient and change over time in the same patient. Symptomatic awareness of hypoglycemia may be less pronounced in patients with longstanding diabetes, in patients with diabetic neuropathy, using drugs that block the sympathetic nervous system (e.g., beta-blockers) [see Drug Interactions ( 7 )], or who experience recurrent hypoglycemia.

The long-acting effect of TRESIBA may delay recovery from hypoglycemia compared to shorter-acting insulins. Risk Factors for Hypoglycemia The risk of h…

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 ).

6.1Clinical Trial 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. 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.
