Update: Two New Invokana Amputation Lawsuits Filed in New Jersey
January 4, 2018 – Two recent lawsuits filed in New Jersey State Court have brought renewed attention to the amputation risk associated with Janssen Pharmaceuticals’ type 2 diabetes medicine Invokana. Both plaintiffs were forced to have a foot and leg amputated below the knee following less than 1 year of treatment with the drug, according to Ring of Fire.
What’s the Problem?
May 18, 2016 – The FDA warning was issued in response to the results of an ongoing trial known as Canagliflozin Cardiovascular Assessment Study (CANVAS), which is expected to be completed next year. Preliminary findings from the study indicate that type 2 diabetics who took canagliflozin were more likely to require a leg, foot or toe amputation compared to patients who took other types of drugs. Although the agency acknowledged that additional studies are needed to determine whether canagliflozin is responsible for the increased amputation risk, it nevertheless advised patients to seek immediate medical attention if they experience the following symptoms in their legs or feet:
FDA also cautioned that diabetes patients should never switch or quit taking a medication without consulting their physician first, as doing so could lead to uncontrolled blood sugar levels, blindness, nerve / kidney damage, and heart disease.
EMA Requests Data on Invokana Amputations
In response to the FDA warning on canagliflozin, the European Medicines Agency’s (EMA) Pharmacovigilance Risk Assessment Committee (PRAC) has asked Janssen for more information about the amputation risk associated with Invokana, and whether any changes to the way the med is used should be made in the EU, according to Medscape.
