UPDATE: Invokana Doubles Ketoacidosis Risk, Study Finds

Invokana doubles the risk of ketoacidosis compared to diabetes drugs in the DPP-4 inhibitor class, according to a study published in the New England Journal of Medicine in June 2017. An estimated 5 to 8 patients per 1,000 starting Invokana will develop ketoacidosis, a life-threatening condition involving too much acid in the blood. Click here to read more.

Invokana Lawsuits Centralized in New Jersey

In December 2016, judges centralized nearly 100 lawsuits involving ketoacidosis, kidney failure, and other side effects of Invokana into Multi-District Litigation (MDL No. 2750) in the U.S. District Court for New Jersey under Judge Brian R. Martinotti. Lawyers requested the same venue in September.

What is Invokana?

Invokana (canagliflozin) is a prescription medication for the treatment of type-2 diabetes. It is made by Johnson & Johnson’s Janssen Pharmaceuticals unit and was approved by the FDA in March 2013.

How Does It Work?

Invokana relies on the kidneys to work. It stops the kidneys from re-absorbing glucose and helps the kidneys excrete more glucose in urine. When it was approved in 2013, Invokana was the first drug in a new class of diabetes medications known as sodium-glucose cotransporter-2 (SGLT2) inhibitors.

FDA Issues Ketoacidosis Warnings

In May 2015, the FDA issued a Safety Warning about the risk of diabetic ketoacidosis from Invokana. The next month, over 100 cases were reported by the European Medicines Agency (EMA). In December 2015, the FDA updated the label on Invokana to include ketoacidosis. Invokana patients may have normal or only mildly-elevated blood-sugar levels when they develop this side effect. The unusual symptoms may delay diagnosis or treatment, which could lead to complications like coma or death.

FDA Strengthens Kidney Injury Warnings

In June 2016, the FDA issued a Safety Warning about the risk of acute kidney injury from Invokana. The agency has received over 100 confirmed reports. Risk-factors include common medications like diuretics, blood pressure drugs (ARBs and ACE inhibitors), and painkillers like ibuprofen. Click here to read more.

Invokana: Foot and Toe Amputations

In May 2016, the FDA warned that Invokana was associated with a doubled increased risk of leg and foot amputations in an ongoing clinical trial. Preliminary data from the CANVAS study found that 7 in 1,000 patients on Invokana (100-mg/day) had amputations, compared to 3 in 1,000 on a placebo. Click here to read more.

Invokana ‘Black Box’ Warning for Amputation Risk

In May 2017, the FDA ordered drug-makers to add a “Black Box” warning label about amputations. The warnings were issued after data from two large clinical trials (CANVAS and CANVAS-R) concluded that patients on Invokana were twice as likely to require a foot, toe, or leg amputation compared to patients who were not on Invokana. According to the FDA:

“Amputations of the toe and middle foot were most common, but amputations of the leg below and above the knee also occurred. Some patients had multiple amputations, or both legs amputated.”

Side Effects of Invokana

Invokana is a diuretic that causes patients to urinate more frequently, which helps reduce blood-sugar levels. The most common side effects are urinary tract infections (6% of patients) and vaginal yeast infections (10% of women). Patients on Invokana have also experienced severe side effects, such as:

What is Ketoacidosis?

Diabetic ketoacidosis (ketosis) occurs when the body is unable to use sugar (glucose) in the bloodstream as a fuel source, and must instead break down fat cells. When fat cells break down, acidic waste products called ketones build up in the blood and urine. Symptoms may include:

  • Decreased alertness
  • Deep, rapid breathing
  • Dry skin and mouth
  • Flushed face
  • Frequent urination or thirst that lasts a day or more
  • Fruity-smelling breath
  • Headache
  • Muscle stiffness or aches
  • Nausea and vomiting
  • Stomach pain

Invokana and Type-1 Diabetes

The FDA has not approved Invokana for type-1 diabetes, but doctors sometimes prescribe it “off-label” to improve blood-sugar control. In April 2016, Diabetes Care published a study linking the use of Invokana (canagliflozin) with an increased risk of diabetic ketoacidosis (DKA). Ketone-related adverse events occurred in 5-10% of type-1 diabetic patients on 100-mg or 300-mg doses in addition to insulin. Click here to read more.
