• Liraglutide, one of the components of XULTOPHY 100/3.6, causes dose-dependent and treatment-duration-dependent thyroid C-cell tumors at clinically relevant exposures in both genders of rats and mice. It is unknown whether XULTOPHY 100/3.6 causes thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans, as the human relevance of liraglutide-induced rodent thyroid C-cell tumors has not been determined [see Warnings and Precautions ( 5.1 ), Nonclinical Toxicology (13)]. • XULTOPHY 100/3.6 is contraindicated in patients with a personal or family history of MTC and in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Counsel patients regarding the potential risk for MTC with the use of XULTOPHY 100/3.6 and inform them of symptoms of thyroid tumors (e.g., a mass in the neck, dysphagia, dyspnea, persistent hoarseness). Routine monitoring of serum calcitonin or using thyroid ultrasound is of uncertain value for early detection of MTC in patients treated with XULTOPHY 100/3.6 [see Contraindications (4), Warnings and Precautions (5.1)].

•Instruct patients who miss a dose of XULTOPHY 100/3.6 to resume the once-daily dosage regimen as prescribed with the next scheduled dose. Do not administer an extra dose or increase the dose to make up for the missed dose. •If more than three days have elapsed since the last XULTOPHY 100/3.6 dose, reinitiate XULTOPHY 100/3.6 at the recommended starting dose to mitigate the risk of gastrointestinal adverse reactions associated with reinitiation of treatment [see Dosage and Administration (2.1, 2.2, 2.3)].

•The XULTOPHY 100/3.6 pen is for single-patient-use only [see Warnings and Precautions ( 5.3)]. •Train patients on proper use and injection technique before initiating XULTOPHY 100/3.6. •Always check the label on the XULTOPHY 100/3.6 pen before administration [see Warnings and Precautions ( 5.5)]. •Inspect visually for particulate matter and discoloration prior to administration. Only use XULTOPHY 100/3.6 if the solution appears clear and colorless. •Inject XULTOPHY 100/3.6 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 (5.4), 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 (5.4)]. •Use XULTOPHY 100/3.6 with caution in patients with visual impairment who may rely on audible clicks to dial their dose. •The XULTOPHY 100/3.6 pen dials in one-unit increments. •Do not administer XULTOPHY 100/3.6 intravenously or in an insulin infusion pump. •Do not dilute or mix XULTOPHY 100/3.6 with any other insulin or solutions. •Do not split the dose of XULTOPHY 100/3.6.

XULTOPHY 100/3.6 is contraindicated: •In patients with a personal or family history of medullary thyroid carcinoma (MTC) or in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2) [see Warnings and Precautions (5.1)]. •During episodes of hypoglycemia [see Warnings and Precautions (5.6)]. •In patients with hypersensitivity to insulin degludec, liraglutide, or any of the excipients in XULTOPHY 100/3.6. Serious hypersensitivity reactions including anaphylactic reactions and angioedema have been reported with liraglutide, one of the components of XULTOPHY 100/3.6 [see Warnings and Precautions (5.9)]. •Patients with a personal or family history of medullary thyroid carcinoma or in patients with Multiple Endocrine Neoplasia syndrome type 2 (4) •During episodes of hypoglycemia (4) •Patients with a serious hypersensitivity reaction to insulin degludec, liraglutide, or any of the excipients in XULTOPHY 100/3.6 (4)

• Acute Pancreatitis: Has been observed in patients treated with GLP-1 receptor agonists, including liraglutide. Discontinue if pancreatitis is suspected. (5.2) • Never share a XULTOPHY 100/3.6 pen between patients, even if the needle is changed. (5.3) • 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. (5.4) • Overdose due to medication errors: XULTOPHY 100/3.6 contains two drugs. Instruct patients to check label before injection since accidental mix-ups with insulin containing products can occur. Do not exceed the maximum dose or administer with other GLP-1 receptor agonists. (5.5) • Hypoglycemia: May be life-threatening. Increase monitoring with changes to: dosage, concomitant drugs, meal pattern, physical activity; and in patients with renal impairment or hepatic impairment or hypoglycemia unawareness. (5.6) • Acute Kidney Injury Due to Volume Depletion: Monitor renal function in patients reporting adverse reactions that could lead to volume depletion. (5.7) • Severe Gastrointestinal Adverse Reactions: Use has been associated with gastrointestinal adverse reactions, sometimes severe. XULTOPHY 100/3.6 is not recommended in patients with severe gastroparesis. (5.8) • Hypersensitivity Reactions: Severe, life-threatening, generalized allergy, including anaphylaxis, angioedema, bronchospasm, hypotension, and shock can occur. If a hypersensitivity reaction occurs, discontinue and treat per standard of care. (5.9) • Acute Gallbladder Disease: If cholelithiasis or cholecystitis are suspected, gallbladder studies are indicated. (5.10) • Hypokalemia: May be life-threatening. Monitor potassium levels in patients at risk for hypokalemia and treat if indicated. (5.11) • Fluid retention and congestive heart failure with use of thiazolidinediones (TZDs): Observe for signs and symptoms of heart failure; consider dosage reduction or discontinuation if heart failure occurs. (5.12) • Pulmonary Aspiration During General Anesthesia or Deep Sedation: Has been reported in patients receiving GLP-1 receptor agonists undergoing elective surgeries or procedures. Instruct patients to inform healthcare providers of any planned surgeries or procedures. (5.13)

Liraglutide, one of the components of XULTOPHY 100/3.6, causes dose-dependent and treatment-duration-dependent thyroid C-cell tumors (adenomas and/or carcinomas) at clinically relevant exposures in both genders of rats and mice [see Nonclinical Toxicology (13.1)]. Malignant thyroid C-cell carcinomas were detected in rats and mice. It is unknown whether XULTOPHY 100/3.6 will cause thyroid C-cell tumors, including medullary thyroid carcinoma (MTC), in humans, as the human relevance of liraglutide-induced rodent thyroid C-cell tumors has not been determined. Cases of MTC in patients treated with liraglutide have been reported in the postmarketing period; the data in these reports are insufficient to establish or exclude a causal relationship between MTC and liraglutide use in humans. XULTOPHY 100/3.6 is contraindicated in patients with a personal or family history of MTC or in patients with MEN 2. Counsel patients regarding the potential risk for MTC with the use of XULTOPHY 100/3.6 and inform them of symptoms of thyroid tumors (e.g., a mass in the neck, dysphagia, dyspnea, persistent hoarseness). Routine monitoring of serum calcitonin or using thyroid ultrasound is of uncertain value for early detection of MTC in patients treated with XULTOPHY 100/3.6. Such monitoring may increase the risk of unnecessary procedures, due to low test specificity for serum calcitonin and a high background incidence of thyroid disease. Significantly elevated serum calcitonin may indicate MTC and patients with MTC usually have calcitonin values >50 ng/L. If serum calcitonin is measured and found to be elevated, the patient should be further evaluated. Patients with thyroid nodules noted on physical examination or neck imaging should also be further evaluated.

Acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis, has been observed in patients treated with GLP-1 receptor agonists, including liraglutide, one of the components of XULTOPHY 100/3.6 [see Adverse Reactions (6)]. After initiation of XULTOPHY 100/3.6, observe patients carefully for signs and symptoms of acute pancreatitis, which may include persistent or severe abdominal pain (sometimes radiating to the back) and which may or may not be accompanied by nausea or vomiting. If pancreatitis is suspected, discontinue XULTOPHY 100/3.6 and initiate appropriate management.

XULTOPHY 100/3.6 pen must never be shared between patients, even if the needle is changed. Sharing of the pen 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 (5.6)] 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. Adjustments in concomitant oral anti-diabetic treatment may be needed. When initiating XULTOPHY 100/3.6, follow dosing recommendations [see Dosage and Administration (2.1, 2.2, 2.3)].

XULTOPHY 100/3.6 contains two drugs: insulin degludec and liraglutide. Administration of more than 50 units of XULTOPHY 100/3.6 daily can result in overdose of the liraglutide component. Do not exceed the 1.8 mg maximum recommended dose of liraglutide or use with other GLP-1 receptor agonists. Accidental mix-ups between insulin products have been reported. To avoid medication errors between XULTOPHY 100/3.6 (an insulin containing product) and other insulin products, instruct patients to always check the label before each injection.

Hypoglycemia is the most common adverse reaction of insulin containing products, including XULTOPHY 100/3.6 [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). XULTOPHY 100/3.6 (an insulin-containing product) 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, in patients using drugs that block the sympathetic nervous system (e.g., beta-blockers) [see Drug Interactions (7.1 )], or who experience recurrent hypoglycemia. The long-acting effect of insulin degludec may delay recovery from hypoglycemia compared to shorter acting insulins. Risk Factors for Hypoglycemia The risk of hypoglycemia generally increases with intensity of glycemic control. The risk of hypoglycemia after an injection is related to the duration of action of the insulin [see Clinical Pharmacology (12.2)] and, in general, is highest when the glucose lowering effect of the insulin is maximal. As with all insulin containing products, the glucose lowering effect time course of XULTOPHY 100/3.6 may vary among different patients or at different times in the same patients and depends on many conditions, including the area of injection as well as the injection site blood supply and temperature. 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 concomitant drugs [see Drug Interactions (7.1)]. Patients with renal or hepatic impairment may be at higher risk of hypoglycemia [see Use in Specific Populations (8.6, 8.7)]. Risk Mitigation Strategies for Hypoglycemia 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.

There have been postmarketing reports of acute kidney injury, in some cases requiring hemodialysis, in patients treated with liraglutide, one of the components of XULTOPHY 100/3.6 [see Adverse Reactions (6.2)]. The majority of the reported events occurred in patients who experienced gastrointestinal reactions leading to dehydration such as nausea, vomiting, or diarrhea [see Adverse Reactions (6.1)]. Monitor renal function in patients reporting adverse reactions to XULTOPHY 100/3.6 that could lead to volume depletion, especially during dosage initiation and escalation of XULTOPHY 100/3.6.

Use of GLP-1 receptor agonists, including liraglutide, one of the components of XULTOPHY 100/3.6, has been associated with gastrointestinal adverse reactions, sometimes severe [see Adverse Reactions (6)]. In a XULTOPHY 100/3.6 clinical trial severe gastrointestinal adverse reactions were reported among patients receiving XULTOPHY 100/3.6 (0.8 %) and patients receiving the active comparators liraglutide (2.9%) and insulin degludec (0.2%) [see Clinical Studies (14.2)].Severe gastrointestinal adverse reactions have also been reported postmarketing with GLP-1 receptor agonists.XULTOPHY 100/3.6 is not recommended in patients with severe gastroparesis.

Severe, life-threatening, generalized allergy, including anaphylaxis, angioedema, bronchospasm, hypotension, and shock can occur with insulins, including XULTOPHY 100/3.6. Allergic reactions (manifested with signs and symptoms such as urticaria, rash, pruritus) have been reported with XULTOPHY 100/3.6. There have been postmarketing reports of serious hypersensitivity reactions (e.g., anaphylactic reactions and angioedema) in patients treated with liraglutide, one of the components of XULTOPHY 100/3.6 [see Adverse Reactions (6.2)]. If a hypersensitivity reaction occurs, discontinue XULTOPHY 100/3.6; treat promptly per standard of care, and monitor until signs and symptoms resolve. Anaphylaxis and angioedema have been reported with other GLP-1 receptor agonists. Use caution in a patient with a history of anaphylaxis or angioedema with another GLP-1 receptor agonist because it is unknown whether such patients will be predisposed to these reactions with XULTOPHY 100/3.6. XULTOPHY 100/3.6 is contraindicated in patients who have had hypersensitivity reactions to insulin degludec, liraglutide or one of the excipients of these products [see Contraindications (4)].

Acute events of gallbladder disease such as cholelithiasis or cholecystitis have been reported in GLP-1 receptor agonist trials and postmarketing. In a cardiovascular outcomes trial (LEADER trial) [see Clinical Studies (14.4)], 3.1% of patients treated with liraglutide, one of the components of XULTOPHY 100/3.6, versus 1.9% of placebo treated patients reported an acute event of gallbladder disease, such as cholelithiasis or cholecystitis [see Adverse Reactions (6.1)]. If cholelithiasis is suspected, gallbladder studies and appropriate clinical follow-up are indicated.

All insulin-containing products, including XULTOPHY 100/3.6, 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, when used in combination with insulin containing products, including XULTOPHY 100/3.6. Fluid retention may lead to or exacerbate congestive heart failure. Patients treated with insulin containing products, including XULTOPHY 100/3.6 and a PPAR-gamma agonist should be observed for signs and symptoms of congestive heart failure. If congestive 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.

XULTOPHY 100/3.6 delays gastric emptying [see Clinical Pharmacology ( 12.1 )] . There have been rare postmarketing reports of pulmonary aspiration in patients receiving GLP-1 receptor agonists undergoing elective surgeries or procedures requiring general anesthesia or deep sedation who had residual gastric contents despite reported adherence to preoperative fasting recommendations. Available data are insufficient to inform recommendations to mitigate the risk of pulmonary aspiration during general anesthesia or deep sedation in patients taking XULTOPHY 100/3.6, including whether modifying preoperative fasting recommendations or temporarily discontinuing XULTOPHY 100/3.6 could reduce the incidence of retained gastric contents. Instruct patients to inform healthcare providers prior to any planned surgeries or procedures if they are taking XULTOPHY 100/3.6.

The following serious adverse reactions are described below or elsewhere in the prescribing information: •Risk of Thyroid C-cell Tumors [see Warnings and Precautions (5.1)] •Acute Pancreatitis [see Warnings and Precautions (5.2)] •Hypoglycemia [see Warnings and Precautions (5.6)] •Acute Kidney Injury Due to Volume Depletion [see Warnings and Precautions (5.7)] •Severe Gastrointestinal Adverse Reactions [see Warnings and Precautions (5.8)] •Hypersensitivity Reactions [see Warnings and Precautions (5.9)] •Acute Gallbladder Disease [see Warnings and Precautions (5.10)] •Hypokalemia [see Warnings and Precautions (5.11)] •Pulmonary Aspiration During General Anesthesia or Deep Sedation [see Warnings and Precautions (5.13)] •Most common adverse reactions (incidence ≥5%) in clinical trials are nasopharyngitis, headache, nausea, diarrhea, increased lipase and upper respiratory tract infection. (6) •Immunogenicity-related events, including urticaria, were more common among liraglutide-treated patients (0.8%) than among comparator-treated patients (0.4%) in clinical trials.

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. XULTOPHY 100/3.6 The data in Table 3 reflect the exposure of 1881 patients to XULTOPHY 100/3.6 and a mean duration of exposure of 33 weeks in trials NCT01336023, NCT01618162, NCT02773368, NCT01676116, NCT01392573, NCT01952145 [see Clinical Studies (14.2 and 14.3)]. The mean age was 57 years and 3% were older than 75 years; 53% were male, 75% were White, 6% were Black or African American and 16% were Hispanic or Latino. The mean body mass index (BMI) was 31.8 kg/m². The mean duration of diabetes was 9 years and the mean HbA_1c at baseline was 8.2%. A history of neuropathy, ophthalmopathy, nephropathy and cardiovascular disease at baseline was reported in 25%, 12%, 7% and 6% respectively. The mean estimated glomerular filtration rate (eGFR) at baseline was 88.3 mL/min/1.73 m² and 6% of the patients had an eGFR less than 60 mL/min/1.73 m².

Hypoglycemia Hypoglycemia was the most commonly observed adverse reaction in patients treated with insulin and insulin containing products, including XULTOPHY 100/3.6 [see Warnings and Precautions (5.6)]. The number of reported hypoglycemia episodes depended on the definition of hypoglycemia used, 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 XULTOPHY 100/3.6 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 phase 3 clinical program [see Clinical Studies (14)], events of severe hypoglycemia were defined as an episode requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions (Table 4). Hypoglycemia episodes with a glucose level below 54 mg/dL associated with or without symptoms is shown in Table 4. No clinically important differences in risk of severe hypoglycemia between XULTOPHY 100/3.6 and comparators were observed in clinical trials. Table 4.

* Episodes of hypoglycemia with a glucose level below 54 mg/dL that are associated with or without symptoms of hypoglycemia. Gastrointestinal Adverse Reactions Gastrointestinal adverse reactions including nausea, diarrhea, vomiting, constipation, dyspepsia, gastritis, abdominal pain, flatulence, eructation, gastroesophageal reflux disease, abdominal distension and decreased appetite have been reported in patients treated with XULTOPHY 100/3.6. In a XULTOPHY 100/3.6 clinical trial severe gastrointestinal adverse reactions were reported among patients receiving XULTOPHY 100/3.6 (0.8%) and patients receiving the active comparators liraglutide (2.9%) and insulin degludec (0.2%) [see Clinical Studies (14.2)].Gastrointestinal adverse reactions may occur more frequently at the beginning of XULTOPHY 100/3.6 therapy and diminish within a few days or weeks on continued treatment. Papillary thyroid carcinoma Liraglutide In glycemic control trials of liraglutide, there were 7 reported cases of papillary thyroid carcinoma in patients treated with liraglutide and 1 case in a comparator-treated patient (1.5 vs. 0.5 cases per 1,000 patient years). Most of these papillary thyroid carcinomas were <1 cm in greatest diameter and were diagnosed in surgical pathology specimens after thyroidectomy prompted by findings on protocol-specified screening with serum calcitonin or thyroid ultrasound. Pancreatitis Liraglutide In glycemic control trials of liraglutide, there have been 13 cases of pancreatitis among liraglutide-treated patients and 1 case in a comparator (glimepiride) treated patient (2.7 vs. 0.5 cases per 1,000 patient-years). Nine of the 13 cases with liraglutide were reported as acute pancreatitis and four were reported as chronic pancreatitis. In one case in a liraglutide-treated patient, pancreatitis, with necrosis, was observed and led to death; however clinical causality could not be established. Some patients had other risk factors for pancreatitis, such as a history of cholelithiasis or alcohol abuse. Cholelithiasis and cholecystitis Liraglutide In glycemic control trials of liraglutide, the incidence of cholelithiasis was 0.3% in both liraglutide-treated and placebo-treated patients. The incidence of cholecystitis was 0.2% in both liraglutide treated and placebo-treated patients. In a cardiovascular outcomes trial (LEADER trial) [see Clinical Studies (14.4)], the incidence of cholelithiasis was 1.5% (3.9 cases per 1,000 patient years of observation) in liraglutide-treated and 1.1% (2.8 cases per 1,000 patient years of observation) in placebo-treated patients, both on a background of standard of care. The incidence of acute cholecystitis was 1.1% (2.9 cases per 1,000 patient years of observation) in liraglutide-treated and 0.7% (1.9 cases per 1,000 patient years of observation) in placebo-treated patients. The majority of events required hospitalization or cholecystectomy. Initiation of insulin containing products 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. Lipodystrophy Long-term use of insulin containing products, including XULTOPHY 100/3.6, can cause lipodystrophy at the site of repeated injections. Lipodystrophy includes lipohypertrophy (thickening of adipose tissue) and lipoatrophy (thinning of adipose tissue), and may affect absorption [see Dosage and Administration ( 2.5 )]. Peripheral Edema XULTOPHY 100/3.6 may cause sodium retention and edema, particularly if previously poor metabolic control is improved rapidly by intensified therapy. Weight Gain Weight gain can occur with insulin containing products, including XULTOPHY 100/3.6, and has been attributed to the anabolic effects of insulin. In study A, after 26 weeks of treatment, patients converting to XULTOPHY 100/3.6 from liraglutide had a mean increase in body weight of 2 kg. Injection Site reactions As with any insulin and GLP-1 receptor agonist-containing products, patients taking XULTOPHY 100/3.6 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, the proportion of injection site reactions occurring in patients treated with XULTOPHY 100/3.6 was 2.6%. These reactions were usually mild and transitory and they normally disappear during continued treatment. Hypersensitivity Reactions Severe, life-threatening, generalized allergy, including anaphylaxis, generalized skin reactions, angioedema, bronchospasm, hypotension, and shock have occurred with insulin, including XULTOPHY 100/3.6 and may be life threatening [see Warnings and Precautions (5.8)]. Hypersensitivity (manifested with swelling of tongue and lips, diarrhea, nausea, tiredness, and itching) and urticaria were reported. Laboratory tests Bilirubin Liraglutide In the five glycemic control trials of at least 26 weeks duration, mildly elevated serum bilirubin concentrations (elevations to no more than twice the upper limit of the reference range) occurred in 4.0% of liraglutide-treated patients, 2.1% of placebo-treated patients and 3.5% of active-comparator-treated patients. This finding was not accompanied by abnormalities in other liver tests. The significance of this isolated finding is unknown. Calcitonin XULTOPHY 100/3.6 Calcitonin, a biological marker of MTC, was measured throughout the XULTOPHY 100/3.6 clinical development program. Among patients with pretreatment calcitonin <20 ng/L, calcitonin elevations to >20 ng/L occurred in 0.7% of XULTOPHY 100/3.6-treated patients, 0.7% of placebo-treated patients, and 1.1% and 0.7% of active-comparator-treated patients (basal insulins and GLP-1s respectively). The clinical significance of these findings is unknown. Liraglutide Calcitonin, a biological marker of MTC, was measured throughout the liraglutide clinical development program. At the end of the glycemic control trials, adjusted mean serum calcitonin concentrations were higher in liraglutide-treated patients compared to placebo-treated patients but not compared to patients receiving active comparator. Between group differences in adjusted mean serum calcitonin values were approximately 0.1 ng/L or less. Among patients with pretreatment calcitonin <20 ng/L, calcitonin elevations to >20 ng/L occurred in 0.7% of liraglutide-treated patients, 0.3% of placebo-treated patients, and 0.5% of active-comparator-treated patients. The clinical significance of these findings is unknown. Lipase and Amylase Liraglutide In one glycemic control trial in renal impairment patients, a mean increase of 33% for lipase and 15% for amylase from baseline was observed for liraglutide-treated patients while placebo-treated patients had a mean decrease in lipase of 3% and a mean increase in amylase of 1%. In a cardiovascular outcomes trial (LEADER trial) [see Clinical Studies (14.4)], serum lipase and amylase were routinely measured. Among liraglutide-treated patients, 7.9% had a lipase value at any time during treatment of greater than or equal to 3 times the upper limit of normal compared with 4.5% of placebo-treated patients, and 1% of liraglutide-treated patients had an amylase value at any time during treatment of greater than or equal to 3 times the upper limit of normal versus 0.7% of placebo-treated patients. The clinical significance of elevations in lipase or amylase with liraglutide is unknown in the absence of other signs and symptoms of pancreatitis [see Warnings and Precautions (5.2)]. Vital signs Mean increases from baseline in heart rate of 2 to 3 beats per minute have been observed with XULTOPHY 100/3.6 which is attributable to the liraglutide component.

The following additional adverse reactions have been reported during post-approval use. Because these events are reported voluntarily from a population of uncertain size, it is generally not possible to reliably estimate their frequency or establish a causal relationship to drug exposure. Insulin degludec 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. Liraglutide • Gastrointestinal: Acute pancreatitis; hemorrhagic and necrotizing pancreatitis sometimes resulting in death; ileus, and nausea, vomiting and diarrhea leading to dehydration, intestinal obstruction, severe constipation including fecal impaction • Hepatobiliary: Elevations of liver enzymes, hyperbilirubinemia, cholestasis, cholecystitis, cholelithiasis requiring cholecystectomy, hepatitis • Hypersensitivity: Angioedema, anaphylactic reactions, rash, pruritus • Neoplasms: Medullary thyroid carcinoma • Neurologic: Dysgeusia, dysesthesia, dizziness • Pulmonary: Pulmonary aspiration has occurred in patients receiving GLP-1 receptor agonists undergoing elective surgeries or procedures requiring general anesthesia or deep sedation. • Renal: Acute renal failure or worsening of chronic renal failure, sometimes requiring hemodialysis; and increased serum creatinine • Skin and subcutaneous tissue: Cutaneous amyloidosis, alopecia

• Drugs that affect glucose metabolism: Adjustment of XULTOPHY 100/3.6 dosage may be needed; closely monitor blood glucose. (7.1) • Anti-Adrenergic drugs (e.g., beta-blockers, clonidine, guanethidine, and reserpine): Hypoglycemia signs and symptoms may be reduced or absent. (7.1) • Effects of delayed gastric emptying on oral medications: May impact absorption of concomitantly administered oral medications. (7.2)

A number of medications affect glucose metabolism and may require dose adjustment of XULTOPHY 100/3.6 and particularly close monitoring [see Dosage and Administration (2.2), Warnings and Precautions (5.6)].

Drugs That May Increase the Risk of Hypoglycemia
Drugs:	Antidiabetic agents, ACE inhibitors, angiotensin II receptor blocking agents, disopyramide, fibrates, fluoxetine, monoamine oxidase inhibitors, pentoxifylline, pramlintide, salicylates, somatostatin analogs (e.g., octreotide), and sulfonamide antibiotics
Intervention:	Dosage reductions and increased frequency of glucose monitoring may be required when XULTOPHY 100/3.6 is coadministered with these drugs.
Drugs That May Decrease the Blood Glucose Lowering Effect of XULTOPHY 100/3.6
Drugs:	Atypical antipsychotics (e.g., olanzapine and clozapine), corticosteroids, danazol, diuretics, estrogens, glucagon, isoniazid, niacin, oral contraceptives, phenothiazines, progestogens (e.g., in oral contraceptives), protease inhibitors, somatropin, sympathomimetic agents (e.g., albuterol, epinephrine, terbutaline), and thyroid hormones.
Intervention:	Dosage increases and increased frequency of glucose monitoring may be required when XULTOPHY 100/3.6 is coadministered with these drugs.
Drugs That May Increase or Decrease the Blood Glucose Lowering Effect of XULTOPHY 100/3.6
Drugs:	Alcohol, beta-blockers, clonidine, and lithium salts. Pentamidine may cause hypoglycemia, which may sometimes be followed by hyperglycemia.
Intervention:	Dosage adjustment and increased frequency of glucose monitoring may be required when XULTOPHY 100/3.6 is coadministered with these drugs.
Drugs That May Blunt Signs and Symptoms of Hypoglycemia
Drugs:	Beta-blockers, clonidine, guanethidine, and reserpine
Intervention:	Increased frequency of glucose monitoring may be required when XULTOPHY 100/3.6 is coadministered with these drugs.

Liraglutide-containing products, including XULTOPHY 100/3.6, cause a delay of gastric emptying, and thereby have the potential to impact the absorption of concomitantly administered oral medications. In clinical pharmacology trials, liraglutide did not affect the absorption of the tested orally administered medications to any clinically relevant degree [see Clinical Pharmacology (12.3)]. Nonetheless, caution should be exercised when oral medications are concomitantly administered with liraglutide containing products.

Pregnancy: XULTOPHY 100/3.6 should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. (8.1)

Risk Summary Based on animal reproduction studies, there may be risks to the fetus from exposure to liraglutide during pregnancy. XULTOPHY 100/3.6 should be used during pregnancy only if the potential benefit justifies the potential risk to the fetus. There are no available data with XULTOPHY 100/3.6, insulin degludec or liraglutide in pregnant women to inform a drug associated risk for major birth defects and miscarriage. There are clinical considerations regarding the risks of poorly controlled diabetes in pregnancy (see Clinical Considerations). For insulin degludec, rats and rabbits were exposed in animal reproduction studies at 5 times (rat) and 10 times (rabbit) the human exposure at a dose of 0.75 U/kg/day. No adverse outcomes were observed for pregnant animals and offspring (see Data). For liraglutide, animal reproduction studies identified increased adverse developmental outcomes from exposure during pregnancy. Liraglutide exposure was associated with early embryonic deaths and an imbalance in some fetal abnormalities in pregnant rats administered liraglutide during organogenesis at doses that approximate clinical exposures at the maximum recommended human dose (MRHD) of 1.8 mg/day. In pregnant rabbits administered liraglutide during organogenesis, decreased fetal weight and an increased incidence of major fetal abnormalities were seen at exposures below the human exposures at the MRHD (see Data). In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2 to 4% and 15 to 20%, respectively. The estimated background risk of major birth defects is 6 to 10% in women with pregestational diabetes with a peri-conceptional HbA1c>7 and has been reported to be as high as 20 to 25% in women with a peri-conceptional HbA1c>10. The estimated background risk of miscarriage for the indicated population is unknown. Clinical Considerations Disease-Associated Maternal and/or Embryo/fetal Risk Hypoglycemia and hyperglycemia occur more frequently during pregnancy in patients with pre-gestational diabetes. Poorly controlled diabetes in pregnancy increases the maternal risk for diabetic ketoacidosis, preeclampsia, spontaneous abortions, preterm delivery, and delivery complications. Poorly controlled diabetes mellitus increases the fetal risk for major birth defects, stillbirth, macrosomia related morbidity. Data Animal Data Insulin degludec Insulin degludec was investigated in studies covering fertility, embryo-fetal development and pre- and post-natal development in rats and during the period of embryo-fetal development in rabbits. Human insulin (NPH insulin) was included as comparator. In these studies insulin degludec was given subcutaneously at up to 21 U/kg/day in rats and 3.3 U/kg/day in rabbits, resulting in 5 times (rat) and 10 times (rabbit) the human exposure (AUC) at a human subcutaneous dose of 0.75 U/kg/day. Overall the effects of insulin degludec were similar to those observed with human insulin. Liraglutide Female rats given subcutaneous doses of 0.1, 0.25 and 1.0 mg/kg/day liraglutide beginning 2 weeks before mating through gestation day 17 had estimated systemic exposures 0.8-, 3-, and 11-times the human exposure at the MRHD based on plasma AUC comparison. The number of early embryonic deaths in the 1 mg/kg/day group increased slightly. Fetal abnormalities and variations in kidneys and blood vessels, irregular ossification of the skull, and a more complete state of ossification occurred at all doses. Mottled liver and minimally kinked ribs occurred at the highest dose. The incidence of fetal malformations in liraglutide-treated groups exceeding concurrent and historical controls were misshapen oropharynx and/or narrowed opening into larynx at 0.1 mg/kg/day and umbilical hernia at 0.1 and 0.25 mg/kg/day. Pregnant rabbits given subcutaneous doses of 0.01, 0.025 and 0.05 mg/kg/day liraglutide from gestation day 6 through day 18 inclusive, had estimated systemic exposures less than the human exposure at the MRHD of 1.8 mg/day at all doses, based on plasma AUC. Liraglutide decreased fetal weight and dose dependently increased the incidence of total major fetal abnormalities at all doses. The incidence of malformations exceeded concurrent and historical controls at 0.01 mg/kg/day (kidneys, scapula), ≥0.01 mg/kg/day (eyes, forelimb), 0.025 mg/kg/day (brain, tail and sacral vertebrae, major blood vessels and heart, umbilicus), ≥0.025 mg/kg/day (sternum) and at 0.05 mg/kg/day (parietal bones, major blood vessels). Irregular ossification and/or skeletal abnormalities occurred in the skull and jaw, vertebrae and ribs, sternum, pelvis, tail, and scapula; and dose-dependent minor skeletal variations were observed. Visceral abnormalities occurred in blood vessels, lung, liver, and esophagus. Bilobed or bifurcated gallbladder was seen in all treatment groups, but not in the control group. In pregnant female rats given subcutaneous doses of 0.1, 0.25 and 1.0 mg/kg/day liraglutide from gestation day 6 through weaning or termination of nursing on lactation day 24, estimated systemic exposures were 0.8-, 3-, and 11-times human exposure at the MRHD of 1.8 mg/day, based on plasma AUC. A slight delay in parturition was observed in the majority of treated rats. Group mean body weight of neonatal rats from liraglutide-treated dams was lower than neonatal rats from control group dams. Bloody scabs and agitated behavior occurred in male rats descended from dams treated with 1 mg/kg/day liraglutide. Group mean body weight from birth to postpartum day 14 trended lower in F2 generation rats descended from liraglutide-treated rats compared to F2 generation rats descended from controls, but differences did not reach statistical significance for any group.

Risk Summary There are no data on the presence of liraglutide or insulin degludec in human milk, the effects on the breastfed infant, or the effects on milk production. In lactating rats, insulin degludec and liraglutide, the two components of XULTOPHY 100/3.6, were present in milk. The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for XULTOPHY 100/3.6 and any potential adverse effects on the breastfed infant from XULTOPHY 100/3.6 or from the underlying maternal condition. Data Insulin degludec In lactating rats, insulin degludec was present in milk at a concentration lower than that in plasma. Liraglutide In lactating rats, liraglutide was present unchanged in milk at concentrations approximately 50% of maternal plasma concentrations.

Safety and effectiveness of XULTOPHY 100/3.6 have not been established in pediatric patients.

Of the total number of 1,881 subjects in clinical studies of XULTOPHY 100/3.6, 375 (19.9%) were 65 years and over, while 52 (2.8%) were 75 years and over [see Clinical Studies (14)]. No overall differences in safety or effectiveness of XULTOPHY 100/3.6 were observed between patients 65 years of age and older and younger patients. Age had no clinically relevant effect on the pharmacokinetics of XULTOPHY 100/3.6 [see Clinical Pharmacology (12.3)]. In geriatric patients with diabetes, the initial dosing, dose increments, and maintenance dosage should be conservative to avoid hypoglycemic reactions. Hypoglycemia may be more difficult to recognize in geriatric patients.

XULTOPHY 100/3.6 There is limited experience with XULTOPHY 100/3.6 in patients with mild and moderate kidney impairment and when used in these patients, additional glucose monitoring and XULTOPHY 100/3.6 dose adjustments may be required on an individual basis. XULTOPHY 100/3.6 has not been studied in patients with severe kidney impairment [ see Warnings and Precautions (5.7), Clinical Pharmacology (12.3)]. Insulin degludec No clinically relevant difference in the pharmacokinetics of insulin degludec was identified in a study comparing healthy subjects and subjects with kidney impairment including subjects with end stage kidney disease. Liraglutide The safety and efficacy of liraglutide was evaluated in a 26-week clinical study that included patients with moderate kidney impairment (eGFR 30 to 60 mL/min/1.73 m2). In the liraglutide treatment arm of a cardiovascular outcomes trial (LEADER trial) [see Clinical Studies (14.4)], 1932 (41.4%) patients had mild kidney impairment, 999 (21.4%) patients had moderate renal impairment and 117 (2.5%) patients had severe kidney impairment at baseline. No overall differences in safety or efficacy were seen in these patients compared to patients with normal kidney function. There is limited experience with liraglutide in patients with end stage kidney disease.

XULTOPHY 100/3.6 XULTOPHY 100/3.6 has not been studied in patients with hepatic impairment. Insulin degludec No clinically relevant difference in the pharmacokinetics of insulin degludec, one of the components of XULTOPHY 100/3.6, was identified in a study comparing healthy subjects and subjects with hepatic impairment (mild, moderate, and severe hepatic impairment) [see Clinical Pharmacology (12.3)]. Liraglutide There is limited experience in patients with mild, moderate or severe hepatic impairment with liraglutide, one of the components of XULTOPHY 100/3.6 [see Clinical Pharmacology (12.3)].

Hypoglycemia (from insulin and liraglutide) and gastrointestinal adverse reactions (from liraglutide) may develop if a patient is dosed with more XULTOPHY 100/3.6 than required. An excess of insulin-containing products like XULTOPHY 100/3.6 relative to food intake, energy expenditure, or both may lead to severe and sometimes prolonged and life-threatening hypoglycemia and hypokalemia [see Warnings and Precautions (5.6, 5.10 )]. Mild episodes of hypoglycemia usually can be treated with oral glucose. Lowering the drug dosage, and adjustments in meal patterns, or exercise may be needed. More severe episodes of hypoglycemia with coma, seizure, or neurologic impairment may be treated with intramuscular/subcutaneous glucagon for emergency use or concentrated intravenous glucose. After apparent clinical recovery from hypoglycemia, continued observation and additional carbohydrate intake may be necessary to avoid reoccurrence of hypoglycemia. Hypokalemia must be corrected appropriately. Overdoses have been reported in clinical trials and postmarketing use of liraglutide, one of the components of XULTOPHY 100/3.6. Effects have included severe nausea and severe vomiting. In the event of overdosage, consider contacting the Poison Help line (1-800-222-1222) or a medical toxicologist for additional overdosage management recommendations. Initiate appropriate supportive treatment according to the patient’s clinical signs and symptoms.

Insulin degludec Insulin degludec is a long-acting basal human insulin analog. Insulin degludec is produced by a process that includes expression of recombinant DNA in Saccharomyces cerevisiae followed by chemical modification. Insulin degludec differs from human insulin in that the amino acid threonine in position B30 has been omitted and a side-chain consisting of glutamic acid and a C16 fatty acid has been attached (chemical name: LysB29(Nε-hexadecandioyl-γ-Glu) des(B30) human insulin). Insulin degludec has a molecular formula of C274H411N65O81S6 and a molecular weight of 6.104 kDa. It has the following structure: Figure 1. Structural Formula of Insulin degludec Liraglutide Liraglutide is an analog of human GLP-1 and acts as a GLP-1 receptor agonist. The peptide precursor of liraglutide, produced by a process that includes expression of recombinant DNA in Saccharomyces cerevisiae, has been engineered to be 97% homologous to native human GLP-1 by substituting arginine for lysine at position 34. Liraglutide is made by attaching a C16 fatty acid (palmitic acid) with a glutamic acid spacer on the remaining lysine residue at position 26 of the peptide precursor. The molecular formula of liraglutide is C172H265N43O51 and the molecular weight is 3.751 kDa. It has the following structure: Figure 2. Structural Formula of Liraglutide XULTOPHY 100/3.6 (insulin degludec and liraglutide) injection, for subcutaneous use, is a combination of a long-acting basal human insulin analog, insulin degludec, and a GLP-1 receptor agonist, liraglutide. XULTOPHY 100/3.6 is a sterile, aqueous, clear, and colorless solution. Each prefilled pen contains 3 mL equivalent to 300 units insulin degludec and 10.8 mg liraglutide. Each mL contains 100 units insulin degludec and 3.6 mg liraglutide. XULTOPHY 100/3.6 contains the following inactive ingredients per mL: glycerol (19.7 mg), phenol (5.7 mg), zinc (55 mcg), and Water for Injection, USP. XULTOPHY 100/3.6 has a pH of approximately 8.15. Hydrochloric acid or sodium hydroxide may be added to adjust pH. figure_1 figure_2

XULTOPHY 100/3.6 XULTOPHY 100/3.6 is a combination product consisting of insulin degludec and liraglutide. Insulin degludec The primary activity of insulin degludec is the regulation of glucose metabolism. Insulin and its analogs lower blood glucose by stimulating peripheral glucose uptake, especially by skeletal muscle and fat, and by inhibiting hepatic glucose production. Insulin also inhibits lipolysis and proteolysis, and enhances protein synthesis. Liraglutide Liraglutide is a GLP-1 receptor agonist that increases glucose-dependent insulin release, decreases glucagon secretion, and slows gastric emptying.

Following a single-dose administration, XULTOPHY 100/3.6 has a duration of action reflecting the combination of the individual glucodynamic action profiles of insulin degludec and liraglutide. Following once-daily administration, XULTOPHY 100/3.6 lowers fasting plasma glucose levels and postprandial glucose levels. Cardiac Electrophysiology (QTc): XULTOPHY 100/3.6 The effect of XULTOPHY 100/3.6 on QTc has not been studied. Liraglutide The effect of liraglutide, one of the components of XULTOPHY 100/3.6, on cardiac repolarization was tested in a QTc study. Liraglutide, at steady state concentrations with daily doses up to 1.8 mg, did not produce QTc prolongation.

Overall, the pharmacokinetics of insulin degludec and liraglutide were not affected in a clinically relevant manner when administered as XULTOPHY 100/3.6. Absorption In patients with type 2 diabetes mellitus (mean body weight 87.5 kg) reaching the maximum daily dose (50 units/1.8 mg) of XULTOPHY 100/3.6, the estimated mean steady-state exposure (AUC 0-24 h) of insulin degludec was 113 h*nmol/L and of liraglutide 1227 h*ng/mL based on population pharmacokinetic analysis. The corresponding maximum concentrations were 5196 pmol/L for insulin degludec and 55 ng/mL for liraglutide. Steady state concentrations of insulin degludec and liraglutide are reached after 2-3 days of daily administration. Distribution Insulin degludec and liraglutide are extensively bound to plasma proteins >99% and >98%, respectively. Elimination The half-life of insulin degludec is approximately 25 hours and the half-life of liraglutide is approximately 13 hours. Metabolism Insulin degludec Degradation of insulin degludec is similar to that of human insulin; all metabolites formed are inactive. Liraglutide During the initial 24 hours following administration of a single [3H]-liraglutide dose to healthy subjects, the major component in plasma was intact liraglutide. Liraglutide is endogenously metabolized in a similar manner to large proteins without a specific organ as a major route of elimination. Specific Populations Geriatric Patients Age had no clinically relevant effect on the pharmacokinetics of XULTOPHY 100/3.6 based on results from a population pharmacokinetic analysis including adult patients up to 83 years treated with XULTOPHY 100/3.6 [see Use in Specific Populations (8.5)]. Male and Female Patients There were no clinically relevant differences in the pharmacokinetics of XULTOPHY 100/3.6 in male and female patients, based on results from a population pharmacokinetic analysis. Racial or Ethnic Groups There were no clinically relevant differences in the pharmacokinetics of XULTOPHY 100/3.6 between the racial and ethnic groups investigated, based on results from a population pharmacokinetic analysis. Body weight The effect of body weight on the exposure level of the components of XULTOPHY 100/3.6 was investigated in the population pharmacokinetic analysis. Exposure levels decreased with increase in baseline body weight for both insulin degludec and liraglutide. Patients with Renal Impairment XULTOPHY 100/3.6 There is limited experience with XULTOPHY 100/3.6 in patients with mild and moderate renal impairment. XULTOPHY 100/3.6 has not been studied in patients with severe renal impairment [see Warnings and Precautions (5.7)]. Insulin degludec Insulin degludec has been studied in a pharmacokinetic study in 32 subjects (n=6/group) with normal or impaired renal function/end-stage renal disease following administration of a single dose (0.4 U/kg) of insulin degludec. Renal function was defined using creatinine clearance (Clcr) as follows: >80 mL/min (normal), 50-80 mL/min (mild), 30-50 mL/min (moderate) and <30 mL/min (severe). Subjects requiring dialysis were classified as having end-stage renal disease (ESRD). Total exposure (AUCIDeg,0-120h,SD) of insulin degludec was similar in subjects with normal and impaired renal function. No clinically relevant difference in the pharmacokinetics of insulin degludec was identified between healthy subjects and subjects with renal impairment. Hemodialysis did not affect clearance of insulin degludec (CL/FIDeg,SD) in subjects with ESRD [see Warnings and Precautions (5.7)]. Liraglutide The single-dose pharmacokinetics of liraglutide were evaluated in subjects with varying degrees of renal impairment. Subjects with mild (estimated creatinine clearance 50-80 mL/min) to severe (estimated creatinine clearance <30 mL/min) renal impairment and subjects with end-stage renal disease requiring dialysis were included in the trial. Compared to healthy subjects, liraglutide AUC in mild, moderate, and severe renal impairment and in end-stage renal disease was on average 35%, 19%, 29% and 30% lower, respectively [see Warnings and Precautions (5.7)]. Patients with Hepatic Impairment XULTOPHY 100/3.6 XULTOPHY 100/3.6 has not been studied in patients with hepatic impairment. Insulin degludec Insulin degludec 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 dose (0.4 U/kg) of insulin degludec. Hepatic function was defined using Child-Pugh Scores ranging from 5 (mild hepatic impairment) to 15 (severe hepatic impairment). No clinically relevant differences in the pharmacokinetics of insulin degludec were identified between healthy subjects and subjects with hepatic impairment [see Hepatic Impairment (8.7)]. Liraglutide The single-dose pharmacokinetics of liraglutide were evaluated in subjects with varying degrees of hepatic impairment. Subjects with mild (Child Pugh score 5-6) to severe (Child Pugh score >9) hepatic impairment were included in the trial. Compared to healthy subjects, liraglutide AUC in subjects with mild, moderate and severe hepatic impairment was on average 11%, 14% and 42% lower, respectively. Drug Interaction Studies In vitro assessment of drug-drug interactions In vitro data suggest that the potential for pharmacokinetic drug interactions related to CYP interaction and protein binding is low for both the liraglutide and insulin degludec components of XULTOPHY 100/3.6. The delay of gastric emptying with liraglutide one of the components of XULTOPHY 100/3.6 may influence absorption of concomitantly administered oral medicinal products. Interaction studies did not show any clinically relevant delay of absorption. In vivo assessment of drug-drug interactions Liraglutide The drug-drug interaction studies were performed at steady state with liraglutide 1.8 mg/day. Before administration of concomitant treatment, subjects underwent a 0.6 mg weekly dose increase to reach the maximum dose of 1.8 mg/day. Administration of the interacting drugs was timed so that Cmax of liraglutide (8-12 h) would coincide with the absorption peak of the coadministered drugs. Digoxin A single dose of digoxin 1 mg was administered 7 hours after the dose of liraglutide at steady state. The concomitant administration with liraglutide resulted in a reduction of digoxin AUC by 16%; Cmax decreased by 31%. Digoxin median time to maximal concentration (Tmax) was delayed from 1 h to 1.5 h. Lisinopril A single dose of lisinopril 20 mg was administered 5 minutes after the dose of liraglutide at steady state. The co-administration with liraglutide resulted in a reduction of lisinopril AUC by 15%; Cmax decreased by 27%. Lisinopril median Tmax was delayed from 6 h to 8 h with liraglutide. Atorvastatin Liraglutide did not change the overall exposure (AUC) of atorvastatin following a single dose of atorvastatin 40 mg, administered 5 hours after the dose of liraglutide at steady state. Atorvastatin Cmax was decreased by 38% and median Tmax was delayed from 1 to 3 hours with liraglutide. Acetaminophen Liraglutide did not change the overall exposure (AUC) of acetaminophen following a single dose of acetaminophen 1,000 mg, administered 8 hours after the dose of liraglutide at steady state. Acetaminophen Cmax was decreased by 31% and median Tmax was delayed up to 15 minutes. Griseofulvin Liraglutide did not change the overall exposure (AUC) of griseofulvin following co-administration of a single dose of griseofulvin 500 mg with liraglutide at steady state. Griseofulvin Cmax increased by 37% while median Tmax did not change. Oral Contraceptives A single dose of an oral contraceptive combination product containing 0.03 mg ethinylestradiol and 0.15 mg levonorgestrel was administered under fed conditions and 7 hours after the dose of liraglutide at steady state. Liraglutide lowered ethinylestradiol and levonorgestrel Cmax by 12% and 13%, respectively. There was no effect of liraglutide on the overall exposure (AUC) of ethinylestradiol. Liraglutide increased the levonorgestrel AUC0-∞ by 18%. Liraglutide delayed Tmax for both ethinylestradiol and levonorgestrel by 1.5 hours.

The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies, including those of XULTOPHY 100/3.6, insulin degludec, or liraglutide. XULTOPHY 100/3.6 Administration of XULTOPHY 100/3.6 may cause formation of antibodies against insulin degludec and/or liraglutide. In rare cases, the presence of such antibodies may necessitate adjustment of the XULTOPHY 100/3.6 dose in order to correct a tendency to hyper- or hypoglycemia. During the 26-52-week clinical trials where antibodies were measured in patients receiving XULTOPHY 100/3.6, 90/812 (11%) patients were positive for insulin degludec specific antibodies at end of treatment vs. 22/936 (2%) at baseline, 250/811 (31%) patients were positive for antibodies cross-reacting with human insulin at end of treatment vs. 136/930 (15%) at baseline. 17/815 (2%) of patients developed treatment induced anti-liraglutide antibodies. No patients had preexisting anti-liraglutide antibodies. Antibody formation has not been associated with reduced efficacy of XULTOPHY 100/3.6. Liraglutide A subset of liraglutide-treated patients (1104 of 2501, 44%) in five adult double-blind clinical trials of 26-weeks duration or longer were tested for the presence of anti-liraglutide antibodies at the end of treatment [see Clinical Studies (14.1)] and 102/1104 (9%) of liraglutide-treated patients developed anti-liraglutide antibodies. Of these 102 liraglutide-treated patients, 56 (5%) patients developed antibodies that cross-reacted with native GLP-1. These cross-reacting antibodies were not tested for neutralizing effect against native GLP-1, and thus the potential for clinically significant neutralization of native GLP-1 was not assessed. Antibodies that had a neutralizing effect on liraglutide in an in vitro assay occurred in 12 (1% ) of the liraglutide-treated patients. There was no identified clinically significant effect of anti-liraglutide antibodies on effectiveness of liraglutide. In five double-blind glycemic control trials of liraglutide, events from a composite of adverse events potentially related to immunogenicity (e.g., urticaria, angioedema) occurred among 0.8% of liraglutide-treated patients and among 0.4% of comparator-treated patients. Urticaria accounted for approximately one-half of the events in this composite for liraglutide-treated patients. Patients who developed anti-liraglutide antibodies were not more likely to develop events from the immunogenicity events composite than were patients who did not develop anti-liraglutide antibodies. In a cardiovascular outcomes trial (LEADER trial) [see Clinical Studies (14.4)], anti-liraglutide antibodies were detected in 11 out of the 1247 (0.9%) liraglutide-treated patients with antibody measurements. Of the 11 liraglutide-treated patients who developed anti-liraglutide antibodies, none were observed to develop neutralizing antibodies to liraglutide, and 5 patients (0.4%) developed cross-reacting antibodies against native GLP-1. TRESIBA (insulin degludec ) In a 52-week study of adult insulin-naïve type 2 diabetes mellitus patients, of the patients who received insulin degludec, 13/760 (2%) patients were positive at baseline for anti-insulin degludec antibodies and 46/744 (6%) patients developed anti-insulin degludec antibodies at least once during the study. The 58/60 (97%) patients who were positive for anti-insulin degludec antibodies were also positive for anti-human insulin antibodies.

XULTOPHY 100/3.6 No studies have been conducted with the XULTOPHY 100/3.6 combination to evaluate carcinogenesis, mutagenesis or impairment of fertility. The following data are based upon studies with insulin degludec and liraglutide individually. Insulin degludec Standard 2-year carcinogenicity studies in animals have not been performed to evaluate the carcinogenic potential of insulin degludec. In a 52-week study including human insulin (NPH insulin) as comparator, Sprague-Dawley rats were dosed subcutaneously with insulin degludec at 3.3, 6.7, and 10 U/kg/day, resulting in 5 times the human exposure (AUC) when compared to a human subcutaneous dose of 0.75 U/kg/day. Human insulin was dosed at 6.7 U/kg/day. No treatment-related increases in incidences of hyperplasia, benign or malignant tumors were recorded in female mammary glands from rats dosed with insulin degludec and no treatment related changes in the female mammary gland cell proliferation were found using BrdU incorporation. Further, no treatment related changes in the occurrence of hyperplastic or neoplastic lesions were seen in any animals dosed with insulin degludec when compared to vehicle or human insulin. Genotoxicity testing of insulin degludec was not performed. In a combined fertility and embryo-fetal study in male and female rats, treatment with insulin degludec up to 21 U/kg/day (approximately 5 times the human subcutaneous dose of 0.75 U/kg/day, based on U/body surface area) prior to mating and in female rats during gestation had no effect on mating performance and fertility. Liraglutide A 104-week carcinogenicity study was conducted in male and female CD-1 mice at doses of 0.03, 0.2, 1.0, and 3.0 mg/kg/day liraglutide administered by bolus subcutaneous injection yielding systemic exposures 0.2-, 2-, 10- and 45-times the human exposure, respectively, at the MRHD of 1.8 mg/day based on plasma AUC comparison. A dose-related increase in benign thyroid C-cell adenomas was seen in the 1.0 and the 3.0 mg/kg/day groups with incidences of 13% and 19% in males and 6% and 20% in females, respectively. C-cell adenomas did not occur in control groups or 0.03 and 0.2 mg/kg/day groups. Treatment-related malignant C-cell carcinomas occurred in 3% of females in the 3.0 mg/kg/day group. Thyroid C-cell tumors are rare findings during carcinogenicity testing in mice. A treatment-related increase in fibrosarcomas was seen on the dorsal skin and subcutis, the body surface used for drug injection, in males in the 3 mg/kg/day group. These fibrosarcomas were attributed to the high local concentration of drug near the injection site. The liraglutide concentration in the clinical formulation (6 mg/mL) is 10-times higher than the concentration in the formulation used to administer 3 mg/kg/day liraglutide to mice in the carcinogenicity study (0.6 mg/mL). A 104-week carcinogenicity study was conducted in male and female Sprague Dawley rats at doses of 0.075, 0.25 and 0.75 mg/kg/day liraglutide administered by bolus subcutaneous injection with exposures 0.5-, 2- and 8-times the human exposure, respectively, resulting from the MRHD based on plasma AUC comparison. A treatment-related increase in benign thyroid C-cell adenomas was seen in males in 0.25 and 0.75 mg/kg/day liraglutide groups with incidences of 12%, 16%, 42%, and 46% and in all female liraglutide-treated groups with incidences of 10%, 27%, 33%, and 56% in 0 (control), 0.075, 0.25, and 0.75 mg/kg/day groups, respectively. A treatment-related increase in malignant thyroid C-cell carcinomas was observed in all male liraglutide-treated groups with incidences of 2%, 8%, 6%, and 14% and in females at 0.25 and 0.75 mg/kg/day with incidences of 0%, 0%, 4%, and 6% in 0 (control), 0.075, 0.25, and 0.75 mg/kg/day groups, respectively. Thyroid C-cell carcinomas are rare findings during carcinogenicity testing in rats. Studies in mice demonstrated that liraglutide-induced C-cell proliferation was dependent on the GLP-1 receptor and that liraglutide did not cause activation of the REarranged during Transfection (RET) proto-oncogene in thyroid C-cells. Human relevance of thyroid C-cell tumors in mice and rats is unknown and has not been determined by clinical studies or nonclinical studies [see Boxed Warning, Warnings, Precautions (5.1)]. Liraglutide was negative with and without metabolic activation in the Ames test for mutagenicity and in a human peripheral blood lymphocyte chromosome aberration test for clastogenicity. Liraglutide was negative in repeat-dose in vivo micronucleus tests in rats. In rat fertility studies using subcutaneous doses of 0.1, 0.25 and 1 mg/kg/day liraglutide, males were treated for 4 weeks prior to and throughout mating and females were treated 2 weeks prior to and throughout mating until gestation day 17. No direct adverse effects on male fertility was observed at doses up to 1 mg/kg/day, a high dose yielding an estimated systemic exposure 11- times the human exposure at the MRHD, based on plasma AUC. In female rats, an increase in early embryonic deaths occurred at 1 mg/kg/day. Reduced body weight gain and food consumption were observed in females at the 1 mg/kg/day dose.

A total of 3908 patients with type 2 diabetes mellitus participated in 6 randomized, parallel and active or placebo-controlled phase 3 trials of 26 weeks duration. Three studies were conducted in patients inadequately controlled on one or more OADs (e.g. metformin, pioglitazone, sulfonylurea, or sodium-glucose cotransporter-2 inhibitors (SGLT2i) (Tables 5-7). Three studies were conducted in patients converting from liraglutide or basal insulin: one study was conducted in patients converting from liraglutide (with doses up to 1.8 mg), (Table 8), one study was conducted in patients converting from any basal insulin (Table 9), and one study was conducted in patients converting from insulin glargine U-100 (Table 10). In all trials, XULTOPHY 100/3.6 was titrated twice weekly by increments or decrements of 2 units (2 units insulin degludec/0.072 mg liraglutide), towards a pre-specified fasting blood glucose target. The same titration algorithm was applied for basal insulin comparators.

NCT01336023: The efficacy and safety of XULTOPHY 100/3.6 compared to insulin degludec and liraglutide, all administered once-daily, was studied in a 26-week randomized, open-label, three-arm parallel trial in 1,660 patients with type 2 diabetes mellitus inadequately controlled on 1-2 OADs (metformin or metformin with or without pioglitazone). The mean age of the trial population was 55 years and mean duration of diabetes was 7 years. 51% were male. 62% were White, 7% were Black or African American and 15% were Hispanic or Latino ethnicity, 5% of patients had eGFR <60 mL/min/1.73 m²; no patients had eGFR <30 mL/min/1.73 m². The mean BMI was 31.2 kg/m². The starting dose of XULTOPHY 100/3.6 was 10 units (10 units insulin degludec/0.36 mg liraglutide). The starting dose of insulin degludec was 10 units. XULTOPHY 100/3.6 and insulin degludec were titrated twice weekly towards a target fasting blood glucose goal of 72 to 90 mg/dL. Patients in the liraglutide arm followed a fixed dose escalation scheme with a starting dose of 0.6 mg and a dose increase of 0.6 mg weekly until a daily dose of 1.8 mg was reached. Patients continued on pre-trial treatment with metformin or metformin and pioglitazone throughout the trial. At the end of 26 weeks, treatment with XULTOPHY 100/3.6, insulin degludec, and liraglutide resulted in a reduction in HbA_1c from baseline of 1.81%, 1.35% and 1.21%, respectively, (see Table 5). The end of trial dose of XULTOPHY 100/3.6 was 38 units (38 units insulin degludec/1.37 mg liraglutide). Table 5.

^A p<0.01. Primary endpoint was tested for non-inferiority of XULTOPHY 100/3.6 to insulin degludec based on pre-specified non-inferiority margin of 0.3% and for superiority of XULTOPHY 100/3.6 to liraglutide. ^# Estimated using an ANCOVA with treatment, baseline HbA_1c stratum, sub-study, concomitant diabetes treatment and country as factors and baseline response as covariate. Multiple imputation modeled “return to baseline” of the treatment effect for subjects having missing week 26 data. ^## Patients with missing HbA_1c value at week 26 data were considered non-responders. There were 11.8% of subjects in the XULTOPHY 100/3.6 arm, 12.3% in the insulin degludec arm and 15.5% in the liraglutide arm for whom HbA_1c data was missing at week 26. NCT01618162: The efficacy and safety of XULTOPHY 100/3.6 compared to placebo were studied in a 26-week randomized, double-blind, treat-to-target trial in 435 patients with type 2 diabetes mellitus inadequately controlled on sulfonylurea alone or in combination with metformin. The mean age of the trial population was 60 years, and mean duration of diabetes was 9 years. 52% were male. 75% were White, 7% were Black or African American and 9% were Hispanic or Latino ethnicity, 11% of patients had eGFR < 60 mL/min/1.73 m²; no patients had eGFR <30 mL/min/1.73 m². The mean BMI was 31.5 kg/m². XULTOPHY 100/3.6 was started at 10 units (10 units insulin degludec/0.36 mg liraglutide) and titrated twice weekly towards a target fasting blood glucose goal of 72 to108 mg/dL. Patients continued on pre-trial treatment with sulfonylurea, with or without metformin throughout the trial. Treatment with XULTOPHY 100/3.6 for 26 weeks resulted in a statistically significant reduction in mean HbA_1c compared to placebo (see Table 6). The end of trial dose of XULTOPHY 100/3.6 was 28 units (28 units insulin degludec/1.01 mg liraglutide). Table 6.

NCT02773368: The efficacy and safety of XULTOPHY 100/3.6 compared to insulin glargine U-100, both administered once-daily, were studied in a 26-week randomized, open-label, two-arm parallel trial in 420 patients with type 2 diabetes mellitus inadequately controlled on a SGLT2i alone or in combination with other OADs [with or without metformin, pioglitazone, and/or dipeptidyl peptidase-4 9DPP-4) inhibitor]. At randomization, the DPP-4 inhibitor was discontinued. The mean age of the trial population was 57 years and mean duration of diabetes was 10 years. 59% were male. 82% were White, 1% were Black or African American and 16% were Hispanic or Latino ethnicity, 3% of patients had eGFR <60 mL/min/1.73 m²; none of the patients had eGFR <30 mL/min/1.73 m². The mean BMI was 31.2 kg/m². The starting dose of XULTOPHY 100/3.6 was 10 units (10 units insulin degludec/0.36 mg liraglutide). The starting dose of insulin glargine U-100 was 10 units. XULTOPHY 100/3.6 and insulin glargine U-100 were titrated twice weekly to target a fasting blood glucose goal of 72 to 90 mg/dL. Patients could not increase the dose of XULTOPHY 100/3.6 and insulin glargine U-100 by more than 4 units per week, and there was no maximum allowed dose of insulin glargine. The patients continued on pretrial treatment with SGLT2i, with or without other OADs throughout the entire trial. The targeted fasting blood glucose goal was achieved by 49% of patients randomized to XULTOPHY 100/3.6 and 41.9% of patients randomized to insulin glargine at 26 weeks. At the end of 26 weeks, XULTOPHY 100/3.6 resulted in a reduction in HbA_1c from baseline of 1.97% and insulin glargine U-100 resulted in a reduction of 1.59% (see Table 7). At the end of trial, the average dose of XULTOPHY 100/3.6 was 36 units (36 units insulin degludec/1.3 mg liraglutide) and the dose of insulin glargine was 54 units; it is unclear that these observed differences in insulin doses are clinically important. The difference in HbA_1c effect observed at 26 weeks may not necessarily reflect the effect in the care setting where insulin glargine may be more rapidly titrated. Table 7.

Converting to XULTOPHY 100/3.6 from GLP-1 receptor agonist NCT01676116: The efficacy and safety of XULTOPHY 100/3.6 (once-daily) compared to unchanged pretrial liraglutide up to a dose of 1.8 mg daily, were studied in a 26-week randomized, open-label, treat-to-target (fasting blood glucose goal of 72 to 90 mg/dL) trial. The trial included 348 patients with type 2 diabetes mellitus inadequately controlled on liraglutide and metformin alone or in combination with pioglitazone, sulfonylurea or both. Oral anti-diabetic drugs (OADs) were continued at pretrial doses throughout the trial, and 22% of subjects were treated with sulfonylureas (SU) in combination with metformin with or without pioglitazone. The mean age of the population was 58 years, and mean duration of diabetes was 10 years. 49% were male. 91% were White, 8% Black or African American. 11% were Hispanic or Latino ethnicity, 6% of patients had eGFR <60 mL/min/1.73 m²; no patient had eGFR <30 mL/min/1.73 m². The mean BMI was 33.1 kg/m². The starting dose of XULTOPHY 100/3.6 was 16 units (16 units insulin degludec/0.58 mg liraglutide), and the average starting dose of liraglutide was 1.7 mg. XULTOPHY 100/3.6 was titrated twice weekly to target a fasting blood glucose goal of 72 to 90 mg/dL. The end of trial dose of XULTOPHY 100/3.6 was 44 units (44 units insulin degludec/1.58 mg liraglutide). The primary endpoint, change in HbA_1c, was tested for superiority of XULTOPHY 100/3.6 to unchanged liraglutide therapy. At the end of 26 weeks, there was a reduction in HbA_1c from baseline of 1.31% for XULTOPHY 100/3.6 and 0.36% for liraglutide (see Table 8). Table 8.

Basal insulin and sulfonylurea/glinides were discontinued at randomization. The mean age of the trial population was 57 years, and mean duration of diabetes was 11 years. 55% were male. 77% were White, 5% Black or African American. 10% were Hispanic or Latino ethnicity, 7% of patients had eGFR < 60 mL/min/1.73 m²; no patient had eGFR <30 mL/min/1.73 m². The mean BMI was 33.7 kg/m². The mean dose of metformin and basal insulin in patients entering the trial was approximately 2 g and 29 units, respectively. The starting dose of XULTOPHY 100/3.6 and insulin degludec was 16 units (16 units insulin degludec/0.58 mg liraglutide) and 16 units, respectively. XULTOPHY 100/3.6 and degludec were to be titrated twice weekly to target a fasting blood glucose goal of 72 to 90 mg/dL. Patients could not increase their dose by more than 4 units per week, and the maximum dose of insulin degludec was limited to 50 units. The targeted fasting blood glucose goal was achieved in 24% of patients randomized to insulin degludec and in 31.6% of the patients randomized to XULTOPHY 100/3.6 at 26 weeks. At the end of 26 weeks, reductions in HbA_1c from baseline of 1.94% for XULTOPHY 100/3.6 and 1.05% for insulin degludec limited to 50 units daily were observed (see Table 9). The mean difference (95% CI) in HbA_1c reduction between XULTOPHY 100/3.6 and insulin degludec was -0.89 [-1.10; -0.68] and statistically significant. The trial was designed to show the contribution of the liraglutide component to glycemic lowering and the insulin degludec dosing algorithm was selected to isolate the effect of the GLP-1 component. At the end of the trial, the doses of insulin degludec were equivalent between treatment groups. The mean final dose of XULTOPHY 100/3.6 and insulin degludec was 46 units (for XULTOPHY 100/3.6: 46 units insulin degludec/1.66 mg liraglutide). The difference in glucose lowering effect observed in the trial may not necessarily reflect the effect that will be observed in the care setting where insulin degludec dosage can be different than that used in the trial.

Multiple imputation modeled “jump to control” of the treatment effect for subjects having missing week 26 data.   ^## Patients with missing HbA_1c data at week 26 were considered non-responders. There were 11.1% of subjects in the XULTOPHY 100/3.6 arm and 13.1% in the insulin degludec arm for whom HbA_1c data was missing at week 26. NCT01952145: The efficacy and safety of XULTOPHY 100/3.6 compared to insulin glargine U-100, both once-daily and added on to metformin, were studied in a 26-week randomized, open-label, two-arm parallel trial in 557 patients with type 2 diabetes mellitus inadequately controlled on insulin glargine U-100 and metformin. The mean age of the trial population was 59 years and mean duration of diabetes was 12 years. 50% were male. 95% were White, 2% Black or African American. 43% were Hispanic or Latino ethnicity, 6% of patients had eGFR < 60mL/min/1.73m²; one patient had eGFR < 30mL/min/1.73m². The mean BMI was 32 kg/m². The mean dose of insulin glargine U-100 in patients entering the trial was 32 units. XULTOPHY 100/3.6 and insulin glargine were to be titrated twice weekly to target a fasting blood glucose goal of 72 to 90 mg/dL. The starting dose of XULTOPHY 100/3.6 was 16 units (16 units insulin degludec/0.58 mg liraglutide). The average starting dose of insulin glargine U-100 was 32 units. Patients could not increase the dose of the two products by more than 4 units per week and there was no maximum allowed dose of insulin glargine. The targeted fasting plasma blood glucose goal was achieved in 39.6% of patients randomized to insulin glargine and 32.9% of the patients randomized to XULTOPHY 100/3.6 at 26 weeks. At the end of 26 weeks, treatment with XULTOPHY 100/3.6 resulted in a reduction in HbA_1c from baseline of 1.67% and was 1.16% for insulin glargine U-100 (see Table 10) and excluded the pre-specified non-inferiority margin of 0.3%. At the end of the trial, the average dose of XULTOPHY 100/3.6 was 41 units (41 units insulin degludec/1.48 mg liraglutide) and the dose of glargine was 66 units, it is unclear that these observed differences in insulin doses are clinically important. The difference in HbA_1c effect observed at 26 weeks may not necessarily reflect the effect in the care setting where insulin glargine may be more rapidly titrated. Table 10.

The effect of XULTOPHY 100/3.6 on the risk of cardiovascular outcomes in patients with type 2 diabetes mellitus and atherosclerotic cardiovascular disease has not been established. The studies below were conducted with liraglutide 1.8 mg and insulin degludec, individually. Liraglutide 1.8 mg The LEADER trial (NCT01179048) randomized 9,340 patients with inadequately controlled type 2 diabetes mellitus and cardiovascular disease to liraglutide 1.8 mg or placebo in addition to standard of care treatments for type 2 diabetes mellitus for a median follow up of 3.5 years. Patients either were 50 years of age or older with established, stable cardiovascular, cerebrovascular, peripheral artery disease, chronic kidney disease or chronic heart failure (80% of patients) or were 60 years of age or older and had other specified risk factors for cardiovascular disease (20% of patients). The population was 64% male, 78% White, 10% Asian, and 8% Black or African American; 12% of the population was Hispanic or Latino. The mean duration of type 2 diabetes mellitus was 13 years, the mean HbA1c was 8.7% and the mean BMI was 33 kg/m2; the mean eGFR at baseline was 79 mL/min/1.73 m2. In total, 96.8% of the patients completed the trial; vital status was available for 99.7%. The primary endpoint was the time from randomization to first occurrence of a major adverse cardiovascular event (MACE) defined as: cardiovascular death, non-fatal myocardial infarction, or non-fatal stroke. No increased risk for MACE was observed with liraglutide 1.8 mg. The total number of primary component MACE endpoints was 1302 (608[13.0%] with liraglutide 1.8 mg and 694 [14.9%] with placebo). Insulin degludec The DEVOTE trial (NCT01959529) randomized 7,637 patients with inadequately controlled type 2 diabetes mellitus and cardiovascular disease to either insulin degludec or insulin glargine U-100. Each was administered once-daily in addition to standard of care treatments for diabetes for a median duration of follow up of 2 years. Patients either were 50 years of age or older and had established, stable cardiovascular, cerebrovascular, peripheral artery disease, chronic kidney disease or chronic heart failure (85% of patients) or were 60 years of age or older and had other specified risk factors for cardiovascular disease (15% of patients). The population was 63% male, 76% White 11% Black or African American, and 10% Asian; 15% of the population was Hispanic or Latino. The mean HbA1c was 8.4% and the mean BMI was 33.6 kg/m2. The baseline mean eGFR was 68 mL/min/1.73m2. In total, 98% of the patients completed the trial; vital status was known at the end of the trial for 99%. The primary endpoint was the time from randomization to the first occurrence of MACE, defined as: cardiovascular death, non-fatal myocardial infarction, or non-fatal stroke. No increased risk for MACE was observed with insulin degludec when compared to insulin glargine U-100. The total number of primary MACE endpoints was 681 (325 [8.5%] with insulin degludec and 356 [9.3%] with insulin glargine).

Instruct patients to discontinue XULTOPHY 100/3.6 promptly and contact their physician if pancreatitis is suspected [see Warnings and Precautions (5.2)]. Never Share a XULTOPHY 100/3.6 Pen Between Patients Advise patients that they must never share a XULTOPHY 100/3.6 pen with another person, even if the needle is changed, because doing so carries a risk for transmission of blood-borne pathogens [see Warnings and Precautions (5.3]. Hyperglycemia or Hypoglycemia with Changes in Insulin Regimen Inform patients that hypoglycemia is the most common adverse reaction with insulin products. Inform patients of the symptoms of hypoglycemia (e.g., impaired ability to concentrate and react). This may present a risk in situations where these abilities are especially important, such as driving or operating other machinery. Advise patients who have frequent hypoglycemia or reduced or absent warning signs of hypoglycemia to use caution when driving or operating machinery. Advise patients that changes in insulin regimen can predispose to hyperglycemia or hypoglycemia and that changes in insulin regimen should be made under close medical supervision [see Warnings and Precautions (5.4)]. Overdose due to Medication Errors Inform patients that XULTOPHY 100/3.6 contains two drugs: insulin degludec and liraglutide. Accidental mix-ups between insulin products have been reported. To avoid medication errors between XULTOPHY 100/3.6 (an insulin containing product) and other insulin products, instruct patients to always check the label before each injection. Advise patients that the administration of more than 50 units of XULTOPHY 100/3.6 daily can result in overdose of the liraglutide component. Instruct patients not to administer concurrently with other glucagon-like peptide-1 receptor agonists [see Warnings and Precautions (5.5)]. Acute Kidney Injury Due to Volume Depletion Inform patients of the potential risk of acute kidney injury due to dehydration associated with gastrointestinal adverse reactions. Advise patients to take precautions to avoid fluid depletion. Inform patients of the signs and symptoms of acute kidney injury and instruct them to promptly report any of these signs or symptoms or persistent (or extended) nausea, vomiting, and diarrhea to their healthcare provider [see Warnings and Precautions (5.7)].

Advise patients on the symptoms of hypersensitivity reactions and instruct them must stop taking XULTOPHY 100/3.6 and seek medical advice promptly [see Warnings and Precautions (5.9)]. Acute Gallbladder Disease Inform patients of the potential risk for cholelithiasis or cholecystitis. Instruct patients to contact their physician if cholelithiasis or cholecystitis is suspected for appropriate clinical follow-up [see Warnings and Precautions (5.10)]. Pulmonary Aspiration During General Anesthesia or Deep Sedation Inform patients that XULTOPHY 100/3.6 may cause their stomach to empty more slowly which may lead to complications with anesthesia or deep sedation during planned surgeries or procedures. Instruct patients to inform healthcare providers prior to any planned surgeries or procedures if they are taking XULTOPHY 100/3.6 [see Warnings and Precautions (5.13)]. Pregnancy Advise a pregnant woman of the potential risk to a fetus. Advise women to inform their healthcare provider if they are pregnant or intend to become pregnant [see Use in Specific Populations (8.1)]. Missed Dose Inform patients not to take an extra dose of XULTOPHY 100/3.6 or increase the dose to make up for the missed dose. Instruct patients who miss a dose of XULTOPHY 100/3.6 to resume the once-daily dosage regimen as prescribed with the next scheduled dose. If more than three days have elapsed since the last XULTOPHY 100/3.6 dose, reinitiate XULTOPHY 100/3.6 at the recommended starting dose to reduce the risk of gastrointestinal adverse reactions associated with reinitiation of treatment.

You can inject doses from 10 to 50 units in a single injection (with each unit of insulin degludec, the pen also delivers 0.036 mg of liraglutide). The dose can be increased by 1 unit at a time. The dose equals the number of units shown in the dose counter. • People who are blind or have vision problems should not use the pen without help from a person trained to use the pen. Supplies you will need to give your XULTOPHY 100/3.6 injection: • XULTOPHY 100/3.6 pen • a new NovoFine or NovoTwist needle • alcohol swab • a sharps container for throwing away used pens and needles. See “After your injection” at the end of these instructions. Preparing your XULTOPHY 100/3.6 pen: • Wash your hands with soap and water. • Before you start to prepare your injection, check the XULTOPHY 100/3.6 pen label before each use to make sure it is your XULTOPHY 100/3.6 pen. • XULTOPHY 100/3.6 should look clear and colorless. Do not use XULTOPHY 100/3.6 if it is cloudy or colored. • Do not use XULTOPHY 100/3.6 past the expiration date printed on the label or 21 days after you start using the pen. • Always use a new needle for each injection to help ensure sterility and prevent blocked needles. Do not reuse or share needles with another person. You may give other people a serious infection or get a serious infection from them. Step 1: • Pull pen cap straight off (See Figure B). Step 2: • Check the liquid in the pen (See Figure C). XULTOPHY 100/3.6 should look clear and colorless. Do not use it if it looks cloudy or colored. Step 3: • Select a new needle. • Pull off the paper tab from the outer needle cap (See Figure D). Step 4: • Push the capped needle straight onto the pen and twist the needle on until it is tight (See Figure E). Step 5: • Pull off the outer needle cap. Do not throw it away (See Figure F). Step 6: • Pull off the inner needle cap and throw it away (See Figure G). Priming your XULTOPHY 100/3.6 pen: Step 7: • Turn the dose selector to select the priming symbol ( ). (See Figure H). Step 8: • Hold the pen with the needle pointing up. Tap the top of the pen gently a few times to let any air bubbles rise to the top (See Figure I). Step 9: • Hold the pen with the needle pointing up. Press and hold in the dose button until the dose counter shows “0”. The “0” must line up with the dose pointer. • A drop of XULTOPHY 100/3.6 should be seen at the needle tip (See Figure J). oIf you do not see a drop of XULTOPHY 100/3.6, repeat steps 7 to 9, no more than 6 times, until a drop of XULTOPHY 100/3.6 appears at the needle tip. oIf you still do not see a drop of XULTOPHY 100/3.6, change the needle and repeat steps 7 to 9. Selecting your dose: Make sure you prime your pen before setting your dose. Step 10: XULTOPHY 100/3.6 pen is made to deliver the number of units that your healthcare provider prescribed. Take your dose exactly as your healthcare provider tells you to. Do not change your dosing schedule without first talking to your healthcare provider. • Turn the dose selector to select the dose you need to inject. The dose pointer should line up with your dose (See Figure K). oIf you select the wrong dose, you can turn the dose selector forwards or backwards to the correct dose. oThe even numbers are printed on the dial. oThe odd numbers are shown as lines. • The XULTOPHY 100/3.6 pen scale will show you how much XULTOPHY 100/3.6 is left in your pen (See Figure L). • To see how much XULTOPHY 100/3.6 is left in your pen: oTurn the dose selector until it stops. The dose counter will line up with the dose that is left in your pen. If the dose counter shows 50, there is a dose of at least 50 units left in your pen. oIf the dose counter shows between 10 and 50, the number shown in the dose counter is the total units left in your pen. • If there is not enough XULTOPHY 100/3.6 left in your pen for a full dose, do not use it. Use a new XULTOPHY 100/3.6 pen. Giving your injection: • Inject your XULTOPHY 100/3.6 exactly as your healthcare provider has shown you. Your healthcare provider should tell you if you need to pinch the skin before injecting. • XULTOPHY 100/3.6 can be injected under the skin (subcutaneously) of your stomach area (abdomen), upper legs (thighs) or upper arms. • Change (rotate) your injection sites within the area you choose for each dose to reduce your risk of getting lipodystrophy (pits in skin or thickened skin) and localized cutaneous amyloidosis (skin with lumps) at the injection sites. Do not use the same injection site for each injection. Do not inject where the skin has pits, is thickened, or has lumps. Do not inject where the skin is tender, bruised, scaly or hard, or into scars or damaged skin. Step 11: • Choose your injection site (stomach, upper legs or upper arms) and wipe the skin with an alcohol swab (See Figure M). Let the injection site dry before you inject your dose. Step 12: • Insert the needle into your skin (See Figure N). o Make sure you can see the dose counter. Do not cover it with your fingers, this can stop your injection. Step 13: • Press and hold down the dose button until the dose counter shows “0” (See Figure O). oThe “0” must line up with the dose pointer. You may hear or feel a click. Step 14: • Keep the needle in your skin after the dose counter has returned to “0” and slowly count to 6 (See Figure P). o When the dose counter returns to “0”, you will not get your full dose until 6 seconds later. o If the needle is removed before you count to 6, you may see a stream of XULTOPHY 100/3.6 coming from the needle tip. o If you see a stream of XULTOPHY 100/3.6 coming from the needle tip you will not get your full dose. If this happens you should check your blood sugar levels more often because you may need more XULTOPHY 100/3.6. Step 15: • Pull the needle out of your skin (See Figure Q). oIf you see blood after you take the needle out of your skin, press the injection site lightly with a piece of gauze or an alcohol swab. Do not rub the area. Step 16: • Carefully remove the needle from the pen after each use and throw it away (See Figure R). o Do not recap the needle. Recapping the needle can lead to needle stick injury. Note: If you do not have a sharps container, follow the steps below: oCarefully slip the needle into the outer needle cap (See Figure S). Safely remove the needle and throw it away as soon as you can. o Do not store the pen with the needle attached. Storing without the needle attached helps prevent leaking, blocking of the needle, and air from entering the pen. Step 17: • Replace the pen cap by pushing it straight on (See Figure T). After your injection: • The used XULTOPHY pen may be thrown away in your household trash after you have removed the needle. • Put your used needles in a FDA-cleared sharps disposal container right away after use. Do not throw away (dispose of) loose needles in your household trash. • If you do not have a FDA-cleared sharps disposal container, you may use a household container that is: omade of a heavy-duty plastic ocan be closed with a tight-fitting, puncture resistant lid, without sharps being able to come out oupright and stable during use oleak-resistant oproperly labeled to warn of hazardous waste inside the container • When your sharps disposal container is almost full, you will need to follow your community guidelines for the right way to dispose of your sharps disposal container. There may be state or local laws about how you should throw away used needles and syringes. For more information about the safe sharps disposal, and for specific information about sharps disposal in the state that you live in, go to the FDA’s website at: http://www.fda.gov/safesharpsdisposal. • Do not dispose of your used sharps disposal container in your household trash unless your community guidelines permit this.
