Gut

Victoza® slows gastric emptying and the rate at which glucose enters the blood after meals.

Liver

Victoza® helps lower hepatic glucose output by suppressing pancreatic glucagon secretion.

Pancreas

Victoza® stimulates beta cells to release insulin when blood glucose is high.


Victoza® is a GLP-1 analog with 97% similarity to native GLP-1 (7-37)a

aGLP-1 (7-37) represents <20% of total circulating endogenous GLP-1.


Victoza® provided 3-for-1 benefits

 

Victoza® is unsurpassed in reducing A1C across multiple studies

GLP-1=glucagon-like peptide-1; MOA=mechanism of action.

Selected Important Safety Information

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 Victoza® 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.
  • Victoza® 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 Victoza® and inform them of symptoms of thyroid tumors (eg, 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 Victoza®.

Indication and Limitations of Use

Victoza® (liraglutide) injection 1.2 mg or 1.8 mg is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

  • Victoza® is not recommended as first-line therapy for patients who have inadequate glycemic control on diet and exercise.
  • Acute pancreatitis, including fatal and nonfatal hemorrhagic or necrotizing pancreatitis, has been observed in patients treated with Victoza® postmarketing. It is unknown whether patients with a history of pancreatitis are at increased risk for pancreatitis while using Victoza®; consider other antidiabetic therapies for these patients.
  • Victoza® is not a substitute for insulin and should not be used in patients with type 1 diabetes mellitus or diabetic ketoacidosis.
  • Concurrent use with prandial insulin has not been studied.

Routine monitoring of serum calcitonin or using thyroid ultrasound is of uncertain value for early detection of MTC in patients treated with Victoza®.

Contraindications

  • Victoza® is contraindicated in patients with a prior serious hypersensitivity reaction to Victoza® or to any of the product components.

Warnings and Precautions

  • Risk of Thyroid C-cell Tumors: If serum calcitonin is measured and found to be elevated, the patient should be referred to an endocrinologist for further evaluation. Patients with thyroid nodules noted on physical examination or neck imaging should also be further evaluated.
  • Pancreatitis: Acute pancreatitis, including fatal and nonfatal hemorrhagic or necrotizing pancreatitis, has been observed in patients treated with Victoza® postmarketing. Observe patients carefully for signs and symptoms of pancreatitis (persistent severe abdominal pain, sometimes radiating to the back with or without vomiting). If pancreatitis is suspected, discontinue Victoza® promptly and if pancreatitis is confirmed, do not restart. Consider other antidiabetic therapies in patients with a history of pancreatitis.
  • Never Share a Victoza® Pen Between Patients, even if the needle is changed. Pen-sharing poses a risk for transmission of blood-borne pathogens.
  • Hypoglycemia: When Victoza® is used with an insulin secretagogue (eg, a sulfonylurea) or insulin, serious hypoglycemia can occur. Consider lowering the dose of the insulin secretagogue or insulin to reduce the risk of hypoglycemia.
  • Renal Impairment: Acute renal failure and worsening of chronic renal failure, which may sometimes require hemodialysis, have been reported postmarketing, usually in association with nausea, vomiting, diarrhea, or dehydration. Use caution when initiating or escalating doses of Victoza® in patients with renal impairment.
  • Hypersensitivity Reactions: Serious hypersensitivity reactions (eg, anaphylaxis and angioedema) have been reported postmarketing. If symptoms of hypersensitivity reactions occur, patients must stop taking Victoza® and promptly seek medical advice.
  • Macrovascular Outcomes: There have been no studies establishing conclusive evidence of macrovascular risk reduction with Victoza® or any other antidiabetic drug.

Adverse Reactions

  • The most common adverse reactions, reported in ≥5% of patients treated with Victoza® and more commonly than in patients treated with placebo, are nausea, diarrhea, headache, and vomiting. Immunogenicity-related events, including urticaria, were more common among Victoza®-treated patients (0.8%) than among comparator-treated patients (0.4%) in clinical trials.

Drug Interactions

  • Victoza® causes a delay of gastric emptying and has the potential to impact the absorption of concomitantly administered oral medications. Caution should be exercised when oral medications are concomitantly administered with Victoza®.

Use in Specific Populations

  • Victoza® has not been studied in patients with type 2 diabetes below 18 years of age and is not recommended for use in pediatric patients.
  • There is limited data in patients with renal or hepatic impairment.
  • Victoza® slows gastric emptying. Victoza® has not been studied in patients with preexisting gastroparesis.

Additional Important Safety Information

In 5 placebo-controlled clinical trials of at least 26 weeks’ duration, hypoglycemia requiring the assistance of another person for treatment occurred in 8 Victoza®-treated patients (7.5 events per 1000 patient-years). Of these 8 Victoza®-treated patients, 7 patients were concomitantly using a sulfonylurea.

In the pool of 5 placebo-controlled clinical trials, withdrawals due to gastrointestinal adverse reactions occurred in 4.3% of Victoza®-treated patients and 0.5% of placebo-treated patients. Withdrawal due to gastrointestinal adverse events mainly occurred during the first 2 to 3 months of the trials.
