Boxed warning
WARNING: RISK OF THYROID C-CELL TUMORS Liraglutide 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 liraglutide 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 ( 13.1 )] . Liraglutide 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 liraglutide 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 liraglutide injection [see Contraindications ( 4 ), Warnings and Precautions ( 5.1 )] .

Indications and uses
1 INDICATIONS AND USAGE Liraglutide Injection is indicated: as an adjunct to diet and exercise to improve glycemic control in adults and pediatric patients aged 10 years and older with type 2 diabetes mellitus. Limitations of Use : Liraglutide Injection contains liraglutide. Coadministration with other liraglutide-containing products is not recommended. Liraglutide Injection is a glucagon-like peptide-1 (GLP-1) receptor agonist indicated: as an adjunct to diet and exercise to improve glycemic control in adults and pediatric patients aged 10 years and older with type 2 diabetes mellitus ( 1 ). Limitations of Use : Coadministration with other liraglutide-containing products is not recommended.
Dosing and administration
2 DOSAGE AND ADMINISTRATION Adult Patients : Initiate at 0.6 mg injected subcutaneously once daily for one week then increase to 1.2 mg daily. If additional glycemic control is required, increase the dose to 1.8 mg daily after one week of treatment with the 1.2 mg daily dose. ( 2.1 ) Pediatric Patients : Initiate at 0.6 mg injected subcutaneously once daily for at least one week. If additional glycemic control is required increase the dose to 1.2 mg daily and if additional glycemic control is still required, increase the dose to 1.8 mg daily after at least one week of treatment with the 1.2 mg daily dose. ( 2.1 ) Inspect visually prior to each injection. Only use if solution is clear, colorless, and contains no particles. ( 2.3 ) Inject liraglutide injection subcutaneously once-daily at any time of day, independently of meals, in the abdomen, thigh or upper arm. ( 2.3 ) When using liraglutide injection with insulin, administer as separate injections. Never mix. ( 2.3 ) 2.1 Recommended Dosage Adult Patients The recommended starting dosage of liraglutide injection is 0.6 mg injected subcutaneously once daily for one week. The 0.6 mg once daily dosage is intended to reduce the risk of gastrointestinal adverse reactions [see Warnings and Precautions ( 5.6 ), Adverse Reactions ( 6.1 )] during initial titration and is not effective for glycemic control in adults. After one week at the 0.6 mg once daily dosage, increase the dosage to 1.2 mg injected subcutaneously once daily. If additional glycemic control is required, increase the dosage to the maximum recommended dosage of 1.8 mg injected subcutaneously once daily after at least one week of treatment with the 1.2 mg once daily dosage. Pediatric Patients Aged 10 Years and Older The recommended starting dosage of liraglutide injection is 0.6 mg injected subcutaneously once daily. If additional glycemic control is required, increase the dosage in 0.6 mg increments after at least one week on the current dosage, to reduce the risk of gastrointestinal adverse reactions [see Warnings and Precautions ( 5.6 ), Adverse Reactions ( 6.1 )] . The maximum recommended dosage is 1.8 mg injected subcutaneously once daily. 2.2 Recommendations Regarding Missed Dose Instruct patients who miss a dose of liraglutide injection 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 3 days have elapsed since the last liraglutide injection dose, reinitiate liraglutide injection at 0.6 mg once daily to reduce the risk of gastrointestinal adverse reactions associated with reinitiation of treatment. Upon reinitiation, liraglutide injection should be titrated at the discretion of the healthcare provider. 2.3 Important Administration Instructions Inspect visually prior to each injection. Only use if solution is clear, colorless, and contains no particles. Inject liraglutide injection subcutaneously once daily at any time of day, independently of meals. Inject liraglutide injection subcutaneously in the abdomen, thigh or upper arm. No dosage adjustment is needed if changing the injection site and/or timing. Rotate injection sites within the same region in order to reduce the risk of cutaneous amyloidosis [see Adverse Reactions ( 6.2 )] . When using liraglutide injection with insulin, administer as separate injections. Never mix. It is acceptable to inject liraglutide injection and insulin in the same body region but the injections should not be adjacent to each other.
Warnings and precautions
5 WARNINGS AND PRECAUTIONS 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 Liraglutide Injection Pen Between Patients , even if the needle is changed. (5.3) Hypoglycemia : Adult patients taking an insulin secretagogue or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia. In pediatric patients 10 years of age and older, the risk of hypoglycemia was higher with liraglutide regardless of insulin and/or metformin use. Reduction in the dose of insulin secretagogues or insulin may be necessary. (5.4) Acute Kidney Injury Due to Volume Depletion : Monitor renal function in patients reporting adverse reactions that could lead to volume depletion. ( 5.5 ) Severe Gastrointestinal Adverse Reactions : Use has been associated with gastrointestinal adverse reactions, sometimes severe. Liraglutide injection is not recommended in patients with severe gastroparesis. ( 5.6 ) Hypersensitivity Reactions : Postmarketing reports of serious hypersensitivity reactions (e.g., anaphylactic reactions and angioedema). Discontinue liraglutide injection and promptly seek medical advice. ( 5.7 ) Acute Gallbladder Disease : If cholelithiasis or cholecystitis are suspected, gallbladder studies are indicated. ( 5.8 ) 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. ( 5.9 ) 5.1 Risk of Thyroid C-cell Tumors Liraglutide 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 liraglutide 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. Liraglutide 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 liraglutide 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 liraglutide. 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. 5.2 Acute Pancreatitis Acute pancreatitis, including fatal and non-fatal hemorrhagic or necrotizing pancreatitis, has been observed in patients treated with GLP-1 receptor agonists, including liraglutide [see Adverse Reactions ( 6 )] . After initiation of liraglutide injection, 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 liraglutide injection and initiate appropriate management. 5.3 Never Share a Liraglutide Injection Pen Between Patients Liraglutide injection pens must never be shared between patients, even if the needle is changed. Pen-sharing poses a risk for transmission of blood-borne pathogens. 5.4 Hypoglycemia Adult patients receiving liraglutide in combination with an insulin secretagogue (e.g., sulfonylurea) or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia. In pediatric patients 10 years of age and older, the risk of hypoglycemia was higher with liraglutide regardless of insulin and/or metformin use. [see Adverse Reactions (6.1) , Drug Interactions (7.2) ] . The risk of hypoglycemia may be lowered by a reduction in the dose of sulfonylurea (or other concomitantly administered insulin secretagogues) or insulin. Inform patients using these concomitant medications and pediatric patients of the risk of hypoglycemia and educate them on the signs and symptoms of hypoglycemia. 5.5 Acute Kidney Injury Due to Volume Depletion There have been postmarketing reports of acute kidney injury, in some cases requiring hemodialysis, in patients treated with liraglutide [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 liraglutide that could lead to volume depletion, especially during dosage initiation and escalation of liraglutide injection [see Use in Specific Populations ( 8.6 )] . 5.6 Severe Gastrointestinal Adverse Reactions Use of GLP-1 receptor agonists, including liraglutide, has been associated with gastrointestinal adverse reactions, sometimes severe [see Adverse Reactions ( 6 )] . In liraglutide injection clinical trials, severe gastrointestinal adverse reactions were reported more frequently among patients receiving liraglutide (1.2 mg 4.4 %, 1.8 mg 4.2 %) than placebo (1.1 %). Severe gastrointestinal adverse reactions have also been reported postmarketing with GLP-1 receptor agonists. Liraglutide injection is not recommended in patients with severe gastroparesis. 5.7 Hypersensitivity Reactions There have been postmarketing reports of serious hypersensitivity reactions (e.g., anaphylactic reactions and angioedema) in patients treated with liraglutide [see Adverse Reactions ( 6.2 )] . If a hypersensitivity reaction occurs, discontinue liraglutide injection; 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-receptor agonist because it is unknown whether such patients will be predisposed to these reactions with liraglutide. Liraglutide is contraindicated in patients who have had a serious hypersensitivity reaction to liraglutide or any of the excipients in liraglutide injection [see Contraindications ( 4 )] . 5.8 Acute Gallbladder Disease Acute events of gallbladder disease such as cholelithiasis or cholecystitis have been reported in GLP-1 receptor agonist trials and postmarketing. If cholelithiasis is suspected, gallbladder studies and appropriate clinical follow-up are indicated. 5.9 Pulmonary Aspiration During General Anesthesia or Deep Sedation Liraglutide delays gastric emptying [see Clinical Pharmacology ( 12.2 )] . 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 liraglutide injection, including whether modifying preoperative fasting recommendations or temporarily discontinuing liraglutide injection 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 liraglutide injection.
Drug interactions
7 DRUG INTERACTIONS Effects of delayed gastric emptying on oral medications : Liraglutide delays gastric emptying and may impact absorption of concomitantly administered oral medications. ( 7 ) 7.1 Effects of Delayed Gastric Emptying on Oral Medications Liraglutide causes a delay of gastric emptying, and thereby has the potential to impact the absorption of concomitantly administered oral medications. In clinical pharmacology trials, liraglutide injection 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 injection. 7.2 Concomitant Use with an Insulin Secretagogue (e.g., Sulfonylurea) or with Insulin Liraglutide stimulates insulin release in the presence of elevated blood glucose concentrations. Patients receiving liraglutide in combination with an insulin secretagogue (e.g., sulfonylurea) or insulin may have an increased risk of hypoglycemia, including severe hypoglycemia. When initiating liraglutide injection, consider reducing the dose of concomitantly administered insulin secretagogues (such as sulfonylureas) or insulin to reduce the risk of hypoglycemia [see Warnings and Precautions ( 5.4 ), Adverse Reactions ( 6.1 )].
Adverse reactions
6 ADVERSE REACTIONS 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 ( 5.4 )] Acute Kidney Injury Due to Volume Depletion [see Warnings and Precautions ( 5.5 )] Severe Gastrointestinal Adverse Reactions [see Warnings and Precautions ( 5.6 )] Hypersensitivity Reactions [see Warnings and Precautions ( 5.7 )] Acute Gallbladder Disease [see Warnings and Precautions ( 5.8 )] Pulmonary Aspiration During General Anesthesia or Deep Sedation [see Warnings and Precautions ( 5.9 )] Most common adverse reactions (incidence ≥5%) in clinical trials are nausea, diarrhea, vomiting, decreased appetite, dyspepsia, constipation. ( 6.1 ) Immunogenicity-related events, including urticaria, were more common among liraglutide-treated patients (0.8%) than among comparator-treated patients (0.4%) in clinical trials. ( 12.6 ) To report SUSPECTED ADVERSE REACTIONS, contact Meitheal Pharmaceuticals Inc. at 1-844-824-8426 or FDA at 1-800-FDA-1088 or www.fda.gov/medwatch . 6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice. Common Adverse Reactions The safety of liraglutide injection in patients with type 2 diabetes mellitus was evaluated in 5 glycemic control, placebo-controlled trials in adults and one trial of 52 weeks duration in pediatric patients 10 years of age and older [see Clinical Studies ( 14.1 )] . The data in Table 1 reflect exposure of 1,673 adult patients to liraglutide and a mean duration of exposure to liraglutide of 37.3 weeks. The mean age of adult patients was 58 years, 4% were 75 years or older and 54% were male. The population was 79% White, 6% Black or African American, 13% Asian; 4% were of Hispanic or Latino ethnicity. At baseline the population had diabetes for an average of 9 years and a mean HbA 1c of 8.4%. Baseline estimated renal function was normal or mildly impaired in 88% and moderately impaired in 12% of the pooled population. Table 1 shows common adverse reactions in adults, excluding hypoglycemia, associated with the use of liraglutide injection for the treatment of type 2 diabetes mellitus. These adverse reactions occurred more commonly on liraglutide than on placebo and occurred in at least 5% of patients treated with liraglutide. Overall, the type, and severity of adverse reactions in pediatric patients 10 years of age and older and above were comparable to that observed in the adult population. Table 1. Adverse Reactions Reported in ≥ 5% of Adult Patients Treated with Liraglutide Injection for Type 2 Diabetes Mellitus Placebo N=661 Liraglutide 1.2 mg N= 645 Liraglutide 1.8 mg N= 1,024 Adverse Reaction (%) (%) (%) Nausea 5 18 20 Diarrhea 4 10 12 Headache 7 11 10 Nasopharyngitis 8 9 10 Vomiting 2 6 9 Decreased appetite 1 10 9 Dyspepsia 1 4 7 Upper Respiratory Tract Infection 6 7 6 Constipation 1 5 5 Back Pain 3 4 5 Cumulative proportions were calculated combining studies using Cochran-Mantel-Haenszel weights. In an analysis of placebo- and active-controlled trials, the types and frequency of common adverse reactions, excluding hypoglycemia, were similar to those listed in Table 1 . Other Adverse Reactions Gastrointestinal Adverse Reactions In the pool of 5 glycemic control, placebo-controlled adult clinical trials, withdrawals due to gastrointestinal adverse reactions, occurred in 4.3% of liraglutide-treated patients and 0.5% of placebo-treated patients. Severe gastrointestinal adverse reactions were reported more frequently among patients receiving liraglutide (1.2 mg 4.4 %, 1.8 mg 4.2 %) than placebo (1.1 %). Withdrawal due to gastrointestinal adverse events mainly occurred during the first 2 to 3 months of the trials. Injection site reactions Injection site reactions (e.g., injection site rash, erythema) were reported in approximately 2% of liraglutide-treated adult patients in the five double-blind, glycemic control trials of at least 26 weeks duration. Less than 0.2% of liraglutide-treated patients discontinued due to injection site reactions. Hypoglycemia In 5 adult glycemic control, placebo-controlled clinical trials of at least 26 weeks duration, hypoglycemia requiring the assistance of another person for treatment occurred in 8 liraglutide-treated patients (7.5 events per 1,000 patient-years). Of these 8 liraglutide-treated patients, 7 patients were concomitantly using a sulfonylurea. Table 2.

In a 26-week placebo-controlled clinical trial in pediatric patients 10 years of age and older with a 26-week open-label extension, 21.2% of liraglutide-treated patients (mean age 14.6 years) with type 2 diabetes mellitus, had hypoglycemia with a blood glucose <54 mg/dL with or without symptoms (335 events per 1,000 patient years). No severe hypoglycemic episodes occurred in the liraglutide treatment group (severe hypoglycemia was defined as an episode requiring assistance of another person to actively administer carbohydrate, glucagon, or other resuscitative actions). Papillary thyroid carcinoma In adult glycemic control trials of liraglutide injection, 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 In glycemic control trials of liraglutide injection, 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 In adult glycemic control trials of liraglutide injection, 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. Laboratory Tests Bilirubin In the five adult 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% 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 Calcitonin, a biological marker of MTC, was measured throughout the clinical development program. At the end of the adult 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 adult 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 In one adult 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%. 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 Liraglutide injection did not have adverse effects on blood pressure. Mean increases from baseline in heart rate of 2 to 3 beats per minute have been observed in adult patients treated with liraglutide compared to placebo. 6.2 Postmarketing Experience The following additional adverse reactions have been reported during post-approval use of liraglutide injection. 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. Gastrointestinal: Acute pancreatitis; hemorrhagic and necrotizing pancreatitis sometimes resulting in death; ileus, intestinal obstruction, severe constipation including fecal impaction, nausea, vomiting and diarrhea leading to dehydration Hepatobiliary: Elevations of liver enzymes, hyperbilirubinemia, cholestasis, cholecystitis, cholelithiasis requiring cholecystectomy, hepatitis Hypersensitivity: Angioedema, anaphylactic reactions, pruritus Neoplasms: Medullary thyroid carcinoma Neurologic: Dysgeusia, dizziness, dysesthesia 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
Clinical studies
14 CLINICAL STUDIES 14.1 Glycemic Control Trials in Adults with Type 2 Diabetes Mellitus In glycemic control trials in adults, liraglutide injection has been studied as monotherapy and in combination with one or two oral anti-diabetic medications or basal insulin. In each of the placebo controlled trials, treatment with liraglutide produced clinically and statistically significant improvements in hemoglobin A 1c and fasting plasma glucose (FPG) compared to placebo. All liraglutide-treated patients started at 0.6 mg/day. The dose was increased in weekly intervals by 0.6 mg to reach 1.2 mg or 1.8 mg for patients randomized to these higher doses. Liraglutide 0.6 mg is not effective for glycemic control and is intended only as a starting dose to reduce gastrointestinal intolerance [see Dosage and Administration (2 )] . Monotherapy In this 52-week trial, 746 adult patients with type 2 diabetes mellitus were randomized to liraglutide 1.2 mg, liraglutide 1.8 mg, or glimepiride 8 mg. Patients who were randomized to glimepiride were initially treated with 2 mg daily for two weeks, increasing to 4 mg daily for another two weeks, and finally increasing to 8 mg daily. Treatment with liraglutide 1.8 mg and 1.2 mg resulted in a statistically significant reduction in HbA 1c compared to glimepiride ( Table 3 ). The percentage of patients who discontinued due to ineffective therapy was 3.6% in the liraglutide 1.8 mg treatment group, 6% in the liraglutide 1.2 mg treatment group, and 10.1% in the glimepiride-treatment group. The mean age of participants was 53 years, and the mean duration of diabetes was 5 years. Participants were 49.7% male, 77.5% White, 12.6% Black or African American and 35% of Hispanic or Latino ethnicity. The mean BMI was 33.1 kg/m 2 . Table 3.

Mean HbA 1c for Adult Patients with Type 2 Diabetes Mellitus who Completed the 52-week Trial and for the Last Observation Carried Forward (LOCF, intent-to-treat) Data at Week 52 (Monotherapy) Combination Therapy Add-on to Metformin In this 26-week trial, 1,091 adult patients with type 2 diabetes mellitus were randomized to liraglutide 0.6 mg, liraglutide 1.2 mg, liraglutide 1.8 mg, placebo, or glimepiride 4 mg (one-half of the maximal approved dose in the United States), all as add-on to metformin. Randomization occurred after a 6-week run-in period consisting of a 3-week initial forced metformin titration period followed by a maintenance period of another 3 weeks. During the titration period, doses of metformin were increased up to 2,000 mg/day. Treatment with liraglutide 1.2 mg and 1.8 mg as add-on to metformin resulted in a significant mean HbA 1c reduction relative to placebo add-on to metformin and resulted in a similar mean HbA 1c reduction relative to glimepiride 4 mg add-on to metformin ( Table 4 ). The percentage of patients who discontinued due to ineffective therapy was 5.4% in the liraglutide 1.8 mg + metformin treatment group, 3.3% in the liraglutide 1.2 mg + metformin treatment group, 23.8% in the placebo + metformin treatment group, and 3.7% in the glimepiride + metformin treated group. The mean age of participants was 57 years, and the mean duration of diabetes was 7 years. Participants were 58.2% male, 87.1% White and 2.4% Black or African American. The mean BMI was 31.0 kg/m 2 .

Patients were to continue their current treatment on metformin at a stable, pre-trial dose level and dosing frequency. The mean age of participants was 56 years, and the mean duration of diabetes was 6 years. Participants were 52.9% male, 86.6% White, 7.2% Black or African American and 16.2% of Hispanic or Latino ethnicity. The mean BMI was 32.8 kg/m 2 . The primary endpoint was the change in HbA 1c from baseline to Week 26. Treatment with liraglutide 1.2 mg and liraglutide 1.8 mg resulted in statistically significant reductions in HbA 1c relative to sitagliptin 100 mg ( Table 5 ). The percentage of patients who discontinued due to ineffective therapy was 3.1% in the liraglutide 1.2 mg group, 0.5% in the liraglutide 1.8 mg treatment group, and 4.1% in the sitagliptin 100 mg treatment group. From a mean baseline body weight of 94 kg, there was a mean reduction of 2.7 kg for liraglutide 1.2 mg, 3.3 kg for liraglutide 1.8 mg, and 0.8 kg for sitagliptin 100 mg. Table 5.

Mean HbA 1c for Adult Patients with Type 2 Diabetes Mellitus who Completed the 26-week Trial and for the Last Observation Carried Forward (LOCF, intent-to-treat) Data at Week 26 Combination Therapy with Metformin and Insulin This 26-week open-label trial enrolled 988 adult patients with type 2 diabetes mellitus with inadequate glycemic control (HbA 1c 7 to 10%) on metformin (≥1,500 mg/day) alone or inadequate glycemic control (HbA 1c 7 to 8.5%) on metformin (≥1,500 mg/day) and a sulfonylurea. Patients who were on metformin and a sulfonylurea discontinued the sulfonylurea then all patients entered a 12-week run-in period during which they received add-on therapy with liraglutide titrated to 1.8 mg once-daily. At the end of the run-in period, 498 patients (50%) achieved HbA 1c <7% with liraglutide 1.8 mg and metformin and continued treatment in a non-randomized, observational arm. Another 167 patients (17%) withdrew from the trial during the run-in period with approximately one-half of these patients doing so because of gastrointestinal adverse reactions [ see Adverse Reactions (6.1) ] . The remaining 323 patients with HbA 1c ≥7% (33% of those who entered the run-in period) were randomized to 26 weeks of once-daily insulin detemir administered in the evening as add-on therapy (N=162) or to continued, unchanged treatment with liraglutide 1.8 mg and metformin (N=161). The starting dose of insulin detemir was 10 units/day and the mean dose at the end of the 26-week randomized period was 39 units/day. During the 26 week randomized treatment period, the percentage of patients who discontinued due to ineffective therapy was 11.2% in the group randomized to continued treatment with liraglutide 1.8 mg and metformin and 1.2% in the group randomized to add-on therapy with insulin detemir. The mean age of participants was 57 years, and the mean duration of diabetes was 8 years. Participants were 55.7% male, 91.3% White, 5.6% Black or African American and 12.5% of Hispanic or Latino ethnicity. The mean BMI was 34 kg/m 2 . Treatment with insulin detemir as add-on to liraglutide 1.8 mg + metformin resulted in statistically significant reductions in HbA 1c and FPG compared to continued, unchanged treatment with liraglutide 1.8 mg + metformin alone ( Table 6 ). From a mean baseline body weight of 96 kg after randomization, there was a mean reduction of 0.3 kg in the patients who received insulin detemir add-on therapy compared to a mean reduction of 1.1 kg in the patients who continued on unchanged treatment with liraglutide 1.8 mg + metformin alone.

Randomization occurred after a 4-week run-in period consisting of an initial, 2-week, forced-glimepiride titration period followed by a maintenance period of another 2 weeks. During the titration period, doses of glimepiride were increased to 4 mg/day. The doses of glimepiride could be reduced (at the discretion of the investigator) from 4 mg/day to 3 mg/day or 2 mg/day (minimum) after randomization, in the event of unacceptable hypoglycemia or other adverse events. The mean age of participants was 56 years, and the mean duration of diabetes was 8 years. Participants were 49.4% male, 64.4% White and 2.8% Black or African American. The mean BMI was 29.9 kg/m 2 . Treatment with liraglutide 1.2 mg and 1.8 mg as add-on to glimepiride resulted in a statistically significant reduction in mean HbA 1c compared to placebo add-on to glimepiride ( Table 7 ). The percentage of patients who discontinued due to ineffective therapy was 3% in the liraglutide 1.8 mg + glimepiride treatment group, 3.5% in the liraglutide 1.2 mg + glimepiride treatment group, 17.5% in the placebo + glimepiride treatment group, and 6.9% in the rosiglitazone + glimepiride treatment group.

Randomization took place after a 6-week run-in period consisting of a 3-week forced metformin and glimepiride titration period followed by a maintenance period of another 3 weeks. During the titration period, doses of metformin and glimepiride were to be increased up to 2,000 mg/day and 4 mg/day, respectively. After randomization, patients randomized to liraglutide 1.8 mg underwent a 2 week period of titration with liraglutide. During the trial, the liraglutide and metformin doses were fixed, although glimepiride and insulin glargine doses could be adjusted. Patients titrated glargine twice-weekly during the first 8 weeks of treatment based on self-measured fasting plasma glucose on the day of titration. After Week 8, the frequency of insulin glargine titration was left to the discretion of the investigator, but, at a minimum, the glargine dose was to be revised, if necessary, at Weeks 12 and 18. Only 20% of glargine-treated patients achieved the pre-specified target fasting plasma glucose of ≤100 mg/dL. Therefore, optimal titration of the insulin glargine dose was not achieved in most patients. The mean age of participants was 58 years, and the mean duration of diabetes was 9 years. Participants were 56.5% male, 75.0% White and 3.6% Black or African American. The mean BMI was 30.5 kg/m 2 . Treatment with liraglutide as add-on to glimepiride and metformin resulted in a statistically significant mean reduction in HbA 1c compared to placebo add-on to glimepiride and metformin ( Table 8 ). The percentage of patients who discontinued due to ineffective therapy was 0.9% in the liraglutide 1.8 mg + metformin + glimepiride treatment group, 0.4% in the insulin glargine + metformin + glimepiride treatment group, and 11.3% in the placebo + metformin + glimepiride treatment group.

Maximally tolerated doses of background therapy were to remain unchanged for the duration of the trial. Patients randomized to exenatide started on a dose of 5 mcg twice-daily for 4 weeks and then were escalated to 10 mcg twice-daily. The mean age of participants was 57 years, and the mean duration of diabetes was 8 years. Participants were 51.9% male, 91.8% White, 5.4% Black or African American and 12.3% of Hispanic or Latino ethnicity. The mean BMI was 32.9 kg/m 2 . Treatment with liraglutide 1.8 mg resulted in statistically significant reductions in HbA 1c and FPG relative to exenatide ( Table 9 ). The percentage of patients who discontinued for ineffective therapy was 0.4% in the liraglutide treatment group and 0% in the exenatide treatment group. Both treatment groups had a mean decrease from baseline in body weight of approximately 3 kg. Table 9.

Patients underwent a 9 week run-in period (3-week forced dose escalation followed by a 6-week dose maintenance phase) with rosiglitazone (starting at 4 mg and increasing to 8 mg/day within 2 weeks) and metformin (starting at 500 mg with increasing weekly increments of 500 mg to a final dose of 2,000 mg/day). Only patients who tolerated the final dose of rosiglitazone (8 mg/day) and metformin (2,000 mg/day) and completed the 6-week dose maintenance phase were eligible for randomization into the trial. The mean age of participants was 55 years, and the mean duration of diabetes was 9 years. Participants were 61.6% male, 84.2% White, 10.2% Black or African American and 16.4% of Hispanic or Latino ethnicity. The mean BMI was 33.9 kg/m 2 . Treatment with liraglutide as add-on to metformin and rosiglitazone produced a statistically significant reduction in mean HbA 1c compared to placebo add-on to metformin and rosiglitazone ( Table 10 ). The percentage of patients who discontinued due to ineffective therapy was 1.7% in the liraglutide 1.8 mg + metformin + rosiglitazone treatment group, 1.7% in the liraglutide 1.2 mg + metformin + rosiglitazone treatment group, and 16.4% in the placebo + metformin + rosiglitazone treatment group.

Liraglutide was added to the patient’s stable pre-trial antidiabetic regimen (insulin therapy and/or metformin, pioglitazone, or sulfonylurea). The dose of liraglutide injection was escalated according to approved labeling to achieve a dose of 1.8 mg per day. The insulin dose was reduced by 20% at randomization for patients with baseline HbA 1c ≤ 8% and fixed until liraglutide dose escalation was complete. Dose reduction of insulin and SU was allowed in case of hypoglycemia; up titration of insulin was allowed but not beyond the pre-trial dose. The mean age of participants was 67 years, and the mean duration of diabetes was 15 years. Participants were 50.5% male, 92.3% White, 6.6% Black or African American, and 7.2% of Hispanic or Latino ethnicity. The mean BMI was 33.9 kg/m 2 . Approximately half of patients had an eGFR between 30 and <45 mL/min/1.73 m 2 . Treatment with liraglutide resulted in a statistically significant reduction in HbA 1c from baseline at Week 26 compared to placebo (see Table 11 ). 123 patients reached the 1.8 mg dose of liraglutide.

Patients were randomized to liraglutide once-daily or placebo once-daily in combination with metformin with or without basal insulin treatment. All patients were on a metformin dose of 1,000 to 2,000 mg prior to randomization. The basal insulin dose was decreased by 20% at randomization and liraglutide was titrated weekly by 0.6 mg for 2 to 3 weeks based on tolerability and an average fasting plasma glucose goal of ≤110 mg/dL. The mean age was 14.6 years: 29.9% were ages 10-14 years, and 70.1% were greater than 14 years of age. 38.1% were male, 64.9% were White, 13.4% were Asian, 11.9% were Black or African American; 29.1% were of Hispanic or Latino ethnicity. The mean BMI was 33.9 kg/m 2 and the mean BMI SDS was 2.9. 18.7% of patients were using basal insulin at baseline. The mean duration of diabetes was 1.9 years and the mean HbA 1c was 7.8%. At week 26, treatment with liraglutide was superior in reducing HbA 1c from baseline versus placebo. The estimated treatment difference in HbA 1c reduction from baseline between liraglutide and placebo was -1.06% with a 95% confidence interval of [-1.65%; -0.46%] (see Table 12 ). Table 12.
