FDA approves liraglutide (Victoza, Novo Nordisk), new non insulin treatment for pediatric patients with type 2 diabetes


The US Food and Drug Administration, extended the indication for the glucose-lowering drug liraglutide (Victoza, Novo Nordisk) to include pediatric patients, as young as 10 years of age, making it the first non insulin drug approved for treating pediatric type 2 diabetes in almost 20 years.
“The FDA encourages drugs to be made available to the widest number of patients possible when there is evidence of safety and efficacy, Victoza has now been shown to improve blood sugar control in pediatric patients with type 2 diabetes. The expanded indication provides an additional treatment option at a time when an increasing number of children are being diagnosed with this disease.” said Lisa Yanoff, M.D, acting director of the Division of Metabolism and Endocrinology Products in the FDA’s Center for Drug Evaluation and Research.

FDA approves new treatment for pediatric patients with type 2 diabetes


The U.S. Food and Drug Administration today approved Victoza (liraglutide) injection for treatment of pediatric patients 10 years or older with type 2 diabetes. Victoza is the first non-insulin drug approved to treat type 2 diabetes in pediatric patients since metformin was approved for pediatric use in 2000. Victoza has been approved to treat adult patients with type 2 diabetes since 2010.
“The FDA encourages drugs to be made available to the widest number of patients possible when there is evidence of safety and efficacy,” said Lisa Yanoff, M.D, acting director of the Division of Metabolism and Endocrinology Products in the FDA’s Center for Drug Evaluation and Research. “Victoza has now been shown to improve blood sugar control in pediatric patients with type 2 diabetes. The expanded indication provides an additional treatment option at a time when an increasing number of children are being diagnosed with this disease.”
Type 2 diabetes is the most common form of diabetes, occurring when the pancreas cannot make enough insulin to keep blood sugar at normal levels. Although type 2 diabetes primarily occurs in patients over the age of 45, the prevalence rate among younger patients has been rising dramatically over the past couple of decades. The Diabetes Report Card published by the U.S. Centers for Disease Control and Prevention estimates that more than 5,000 new cases of type 2 diabetes are diagnosed each year among U.S. youth younger than age 20.
Victoza improves blood sugar levels by creating the same effects in the body as the glucagon-like peptide (GLP-1) receptor protein in the pancreas. GLP-1 is often found in insufficient levels in type 2 diabetes patients. Like GLP-1, Victoza slows digestion, prevents the liver from making too much glucose (a simple sugar), and helps the pancreas produce more insulin when needed. As noted on the label, Victoza is not a substitute for insulin and is not indicated for patients with type 1 diabetes or those with diabetic ketoacidosis, a condition associated with diabetes where the body breaks down fat too quickly because there is inadequate insulin or none at all. Victoza is also indicated to reduce the risk of major adverse cardiovascular events in adults with type 2 diabetes and established cardiovascular disease; however, its effect on major adverse cardiovascular events in pediatrics was not studied and it is not indicated for this use in children.
The efficacy and safety of Victoza for reducing blood sugar in patients with type 2 diabetes was studied in several placebo-controlled trials in adults and one placebo-controlled trial with 134 pediatric patients 10 years and older for more than 26 weeks. Approximately 64% of patients in the pediatric study had a reduction in their hemoglobin A1c (HbA1c) below 7% while on Victoza, compared to only 37% who achieved these results with the placebo. HbA1c is a blood test that is routinely performed to evaluate how well a patient’s diabetes is controlled, and a lower number indicates better control of the disease. These results occurred regardless of whether the patient also took insulin at the same time. Adult patients who took Victoza with insulin or other drugs that increase the amount of insulin the body makes (e.g., sulfonylurea) may have an increased risk of hypoglycemia (low blood sugar). Meanwhile, pediatric patients 10 years and older taking Victoza had a higher risk of hypoglycemia regardless of whether they took other therapies for diabetes.
The prescribing information for Victoza includes a Boxed Warning to advise health care professionals and patients about the increased risk of thyroid C-cell tumors. For this reason, patients who have had, or have family members who have ever had medullary thyroid carcinoma (MTC) should not use Victoza, nor should patients who have an endocrine system condition called multiple endocrine neoplasia syndrome type 2 (MEN 2). In addition, people who have a prior serious hypersensitivity reaction to Victoza or any of the product components should not use Victoza. Victoza also carries warnings about pancreatitis, Victoza pen sharing, hypoglycemia when used in conjunction with certain other drugs known to cause hypoglycemia including insulin and sulfonylurea, renal impairment or kidney failure, hypersensitivity and acute gallbladder disease. The most common side effects are nausea, diarrhea, vomiting, decreased appetite, indigestion and constipation.
The FDA granted this application Priority Review. The approval of Victoza was granted to Novo Nordisk.
The FDA, an agency within the U.S. Department of Health and Human Services, protects the public health by assuring the safety, effectiveness, and security of human and veterinary drugs, vaccines and other biological products for human use, and medical devices. The agency also is responsible for the safety and security of our nation’s food supply, cosmetics, dietary supplements, products that give off electronic radiation, and for regulating tobacco products.

Health Canada pulls all Gentiane Violet Liquid Topical from the market, warns Canadians of potential cancer risk associated with it

    Gentiane Violet Liquid Topical (gentian violet) is a non-prescription drug that has been used to treat infections of the skin (cutaneous) and inside the nose, mouth, and vagina (mucocutaneous). Gentian violet can also be found in Hydrofera Antibacterial Foam Dressings, which are used as external dressings for wounds.
    Health Canada conducted two health risk assessments on gentian violet-containing human therapeutic products: one on the non-prescription drug product and one on the medical devices (foam dressings). These assessments were triggered by the World Health Organization's Codex Alimentarius Commission recommending that regulatory authorities prevent exposure to gentian violet in food because of its potential to cause cancer.1
    Health Canada's risk assessment of the non-prescription drug product concluded that there is evidence based on animal studies in the scientific literature of a potential for a link between gentian violet and cancer. In studies, cases of cancer in animals following oral exposure of gentian violet were noted. There have been no reported cases of cancer in humans associated with the use of topical gentian violet in Canada or internationally.
    Health Canada notified the manufacturer of Gentiane Violet Liquid Topical of the results of the assessment. The manufacturer agreed to voluntarily discontinue marketing of their product in Canada and their health product drug licence has been cancelled.
    Health Canada's risk assessment of medical devices containing gentian violet concluded, based on the limited exposure to gentian violet, that the risk of cancer is unlikely. However, no clinical data to support the safety and effectiveness of the device for pregnant and nursing women has been provided, and as a precaution, Health Canada will work with the manufacturers to update the Instructions for Use to strengthen existing warnings.
    An Information Update will be published to give Canadians more details about this risk, what consumers should do, and further actions taken by Health Canada.
    Following a separate risk assessment for veterinary drugs, manufacturers of these products also agreed to voluntarily discontinue marketing their products in Canada and their drug licence has been cancelled.

Issue

OTTAWA - Health Canada has completed a safety review of human health products and veterinary drugs containing gentian violet and has found that exposure to these products may increase the risk of cancer. Given the seriousness of this risk, Health Canada is advising Canadians to stop using all human and veterinary drug products containing gentian violet.
Gentian violet is an antiseptic dye used to treat fungal infections. Products containing gentian violet have been used on the skin, on mucous membranes (inside the nose, mouth or vagina), on open wounds, or on the nipple of a nursing mother to treat oral thrush in infants.
Health Canada's review was triggered by the World Health Organization's Codex Alimentarius Commission's recommendation on the potential risk of cancer associated with veterinary drug residues in foods, including gentian violet. Although the Commission's recommendations were specific to food residues, Health Canada reviewed the safety of human non-prescription drugs, veterinary drugs and medical devices containing gentian violet.
After completing two safety assessments, the Department concluded that, as with other known cancer causing substances, there is no safe level of these products, and therefore any exposure to these products is a potential cause for concern.

What you should do

  • Stop using all drug products that contain gentian violet, including on animals. Products for humans should be returned to a pharmacy for proper disposal. Animal owners can discuss options for the safe disposal of their products with their veterinarians or local pharmacies.
  • Do not use dressings containing gentian violet for longer than six months or if you are pregnant or nursing.
  • Consult your health care professional if you have used any health products containing gentian violet and have health concerns.
  • Read product labels to verify that health products have been authorized for sale by Health Canada. Authorized health products have an eight-digit Drug Identification Number (DIN), Natural Product Number (NPN) or Homeopathic Drug Number (DIN-HM). You can also check whether products have been authorized for sale by searching the Drug Product DatabaseMedical Devices Active Licence Listing (MDALL) and Licensed Natural Health Product Database.
  • Report any health product-related adverse reactions or complaints to Health Canada.
  • Contact Health Canada at 1-800-267-9675 or by completing an online complaint form if you find a drug product that contains gentian violet in the Canadian marketplace.

What Health Canada is doing

Health Canada worked with all manufacturers with licensed drug products containing gentian violet to remove them from the market.

Human Non-prescription Drugs:

There was only one non-prescription drug product containing gentian violet marketed in Canada. Gentiane Violet Liquid Topical is an antiseptic used to treat infections of the skin and mucous membranes. This product is also known to be used by some nursing mothers to treat oral thrush in infants. The manufacturer has voluntarily stopped marketing this product in Canada and its product licence has been cancelled. The manufacturer indicated that the product was no longer available on the market, so no recall was required.

Veterinary Drugs:

In Canada, there were nine registered veterinary drug products containing gentian violet, four of which were available as of April 2019: Blu Kote Dr Naylors, Cristisol, Guard and Wound Spray, and Wound Clear Spray. These products were used to treat surface wounds and eye infections in food-producing and companion animals (e.g., cattle, poultry, horses, dogs, cats). All manufacturers have voluntarily stopped marketing these products, their product licences have been cancelled, and any products that were on the Canadian market have been recalled.

Medical Devices:

There are currently three licensed medical devices on the market that contain gentian violet. They are all sterile dressings made of polyurethane foam, and are used for wounds such as sores, skin graft sites, abrasions and cuts. They are all made by one manufacturer (Hydrofera). The risk assessment for these devices found that the gentian violet is unlikely to come into direct contact with the skin, therefore these products do not posean increased risk of cancer when used for a short time and in most people. The Department has requested that the manufacturer update the product labels to state that these products should not be used for longer than six months and should not be used by pregnant or nursing women as a precaution because of the lack of information available to support these uses.
Should the Department identify unauthorized health products containing gentian violet being sold in Canada, it will take appropriate and timely action to protect the health and safety of Canadians.
