Indications and Usage

Victoza^® is indicated as an adjunct to diet and exercise to improve glycemic control in adults with type 2 diabetes mellitus.

Because of the uncertain relevance of the rodent thyroid C-cell tumor findings to humans, prescribe Victoza^® only to patients for whom the potential benefits are considered to outweigh the potential risk. Victoza^® is not recommended as first-line therapy for patients who have inadequate glycemic control on diet and exercise.

In clinical trials of Victoza^®, there were more cases of pancreatitis with Victoza^® than with comparators. Victoza^® has not been studied sufficiently in patients with a history of pancreatitis to determine whether these patients are at increased risk for pancreatitis while using Victoza^®. Use with caution in patients with a history of pancreatitis.

Victoza^® is not a substitute for insulin. Victoza^® should not be used in patients with type 1 diabetes mellitus or for the treatment of diabetic ketoacidosis, as it would not be effective in these settings.

Victoza^® has not been studied in combination with prandial insulin.

Important Safety Information

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 human relevance could not be ruled out by clinical or nonclinical studies. 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). Based on the findings in rodents, monitoring with serum calcitonin or thyroid ultrasound was performed during clinical trials, but this may have increased the number of unnecessary thyroid surgeries. It is unknown whether monitoring with serum calcitonin or thyroid ultrasound will mitigate human risk of thyroid C-cell tumors. Patients should be counseled regarding the risk and symptoms of thyroid tumors.

Do not use in patients with a prior serious hypersensitivity reaction to Victoza^® or to any of the product components.

If pancreatitis is suspected, Victoza^® should be discontinued. Victoza^® should not be re-initiated if pancreatitis is confirmed.

When Victoza^® is used with an insulin secretagogue (e.g. 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 has been reported post-marketing, usually in association with nausea, vomiting, diarrhea, or dehydration which may sometimes require hemodialysis. Use caution when initiating or escalating doses of Victoza^® in patients with renal impairment.

Serious hypersensitivity reactions (e.g. anaphylaxis and angioedema) have been reported during postmarketing use of Victoza^®. If symptoms of hypersensitivity reactions occur, patients must stop taking Victoza^® and seek medical advice promptly.

There have been no studies establishing conclusive evidence of macrovascular risk reduction with Victoza^® or any other antidiabetic drug.

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

There is limited data in patients with renal or hepatic impairment.

Counsel patients regarding the risk for MTC and the symptoms of thyroid tumors (e.g. a mass in the neck, dysphagia, dyspnea, or persistent hoarseness).

Patients with thyroid nodules noted on physical examination or neck imaging obtained for other reasons should be referred to an endocrinologist for further evaluation.

Although routine monitoring of serum calcitonin is of uncertain value in patients treated with Victoza^®, if serum calcitonin is measured and found to be elevated, the patient should be referred to an endocrinologist for further evaluation.

After initiation of Victoza^®, and after dose increases, observe patients carefully for signs and symptoms of pancreatitis (including persistent severe abdominal pain, sometimes radiating to the back and which may or may not be accompanied by vomiting).

In the clinical trials of at least 26 weeks duration, hypoglycemia requiring the assistance of another person for treatment occurred in 7 Victoza^®-treated patients and in 2 comparator-treated patients. Six of these 7 patients treated with Victoza^® were also taking a sulfonylurea.

The incidence of withdrawal due to adverse events was 7.8% for Victoza^®-treated patients and 3.4% for comparator-treated patients in the 5 controlled trials of 26 weeks duration or longer. This difference was driven by withdrawals due to gastrointestinal adverse reactions, which occurred in 5.0% of Victoza^®-treated patients and 0.5% of comparator-treated patients. The most common adverse reactions leading to withdrawal for Victoza^®-treated patients were nausea (2.8% versus 0% for comparator) and vomiting (1.5% versus 0.1% for comparator).

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

Victoza^® slows gastric emptying. Victoza^® has not been studied in patients with pre-existing gastroparesis.

In a 52-week monotherapy study (n=745), the adverse reactions reported in ≥5% of patients treated with Victoza^® or ≥5% of patients treated with glimepiride were nausea (28.4% vs 8.5%), diarrhea (17.1% vs 8.9%), vomiting (10.9% vs 3.6%), constipation (9.9% vs 4.8%), upper respiratory tract infection (9.5% vs 5.6%), headache (9.1% vs 9.3%), influenza (7.4% vs 3.6%), urinary tract infection (6.0% vs 4.0%), dizziness (5.8% vs 5.2%), sinusitis (5.6% vs 6.0%), nasopharyngitis (5.2% vs 5.2%), back pain (5.0% vs 4.4%), and hypertension (3.0% vs 6.0%).

Adverse reactions reported in ≥5% of patients and occurring more frequently with Victoza^® compared to exenatide were diarrhea (12.3% vs 12.1%), dyspepsia (8.9% vs 4.7%), and constipation (5.1% vs 2.6%). Rates of gastrointestinal adverse reactions, including nausea, were similar.

In a 26-week open-label study (n=665), the adverse reactions reported in ≥5% of the patients treated with Victoza^® were nausea (23.9% vs 4.6%), headache (10.3% vs 10.0%), diarrhea (9.3% vs 4.6%), and vomiting (8.7% vs 4.1%).
