Abstract

[BOXED_WARNING] WARNING: RISK OF THYROID C-CELL TUMORS 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 injection 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 injection 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 injection 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 ) ]. WARNING: RISK OF THYROID C-CELL TUMORS See full prescribing information for complete boxed warning. • Liraglutide causes thyroid C-cell tumors at clinically relevant exposures in both genders of rats and mice. It is unknown whether liraglutide injection 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 ( 5.1 , 13.1 ) . • Liraglutide injection is contraindicated in patients with a personal or family history of MTC or in patients with Multiple Endocrine Neoplasia syndrome type 2 (MEN 2). Counsel patients regarding the potential risk of MTC and the symptoms of thyroid tumors ( 4 , 5.1 ). [WARNINGS_AND_CAUTIONS] 5 WARNINGS AND PRECAUTIONS Acute Pancreatitis : Has been observed in patients treated with GLP-1 receptor agonists, including liraglutide injection. 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 injection regardless of insulin and/or metformin use. Reduction in the dose of insulin secretagogues or insulin may be necessary. ( 5.4 ) A cute Kidney Injury Due to Volume Depletion : Monitor renal function in patients reporting adverse reactions that could lead to volume depletion. ( 5.5 ) S evere 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 injection 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 injection 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 injection use in humans. Liraglutide injection 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 injection 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. 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 [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 injection-treated patients (0.8%) than among comparator-treated patients (0.4%) in clinical trials. ( 12.6 ) To report SUSPECTED ADVERSE REACTIONS, contact Lupin Pharmaceuticals, Inc. at 1-800-399-2561 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 injection and a mean duration of exposure to liraglutide injection 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 injection than on placebo and occurred in at least 5% of patients treated with liraglutide injection. 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 Cumulative proportions were calculated combining studies using Cochran-Mantel-Haenszel weights. Placebo N=661 Liraglutide 1.2 mg N= 645 Liraglutide 1.8 mg N= 1024 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 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 injection-treated patients and 0.5% of placebo-treated patients. Severe gastrointestinal adverse reactions were reported more frequently among patients receiving liraglutide injection (1.2 mg 4.4 %, 1.8 mg 4.2 %) th [DRUG_INTERACTIONS] 7 DRUG INTERACTIONS Effects of delayed gastric emptying on oral medications: Liraglutide injection delays gastric emptying and may impact absorption of concomitantly administered oral medications. ( 7 ) 7.1 Effects of Delayed Gastric Emptying on Oral Medications Liraglutide injection 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 injection stimulates insulin release in the presence of elevated blood glucose concentrations. Patients receiving liraglutide injection 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 )]. [CONTRAINDICATIONS] 4 CONTRAINDICATIONS Liraglutide injection 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 )] . serious hypersensitivity reaction to liraglutide or to any of the excipients in liraglutide injection. Serious hypersensitivity reactions including anaphylactic reactions and angioedema have been reported with liraglutide injection [see Warnings and Precautions ( 5.7 )]. Patients with a personal or family history of medullary thyroid carcinoma or in patients with Multiple Endocrine Neoplasia syndrome type 2.
