What is Invokana?

Invokana (generic name Canaglifozin) is an orally-administered drug used for the treatment of type-2 diabetes. It was the first of a new class of drugs known as ‘SGLT2 inhibitors’ to be approved by the US FDA. These drugs function by blocking the reabsorption of glucose, causing it instead to be secreted in the urine.

Since the drug was only approved for use in May 2013, many consequences of taking Invokana long-term are still unknown. Due to concerns which arose during the approval process, the FDA required several long-term studies to monitor groups of Invokana users, watching for several potential health complications which may be caused by the drug. The results of these studies are not yet available.

Though it is not FDA-approved for the treatment of type-1 diabetes, Invokana is frequently prescribed off-label for that purpose as well.

Invokana Facts

The FDA’s approval of Invokana caused considerable controversy, with five experts on the fifteen-member panel voting to reject the drug due to unanswered concerns. The latest of these concerns to come to light, following several endocrinological studies, is the link between Invokana use and diabetic ketoacidosis, a serious health condition caused by a build-up of toxic blood acids. At its most serious, ketoacidosis can cause coma or death.

Other serious health concerns include an increase in heart attacks and strokes in Invokana-users, especially in the first 30 days of use. Despite compelling evidence of cardiovascular issues prior to approval of the drug, Invokana’s label carries no warnings to prescribing doctors regarding using caution with patients who already have cardiovascular risks.

Dr. Sanjay Kaul, who voted in favor of approving the drug, even notes “my vote came with many caveats,” due to the lack of available data on Invokana’s risk to patients with moderate to severe renal impairment. He also notes that the drastic increase in genital fungal infections (from four- to seven-fold increased risk) is unlikely to make the drug beloved by patients.

Related drugs have been rejected by the FDA due to concerns with connections to increased cancer risk and liver failure.

To make matters worse, the drug has a fairly weak glucose-lowering potential compared to drugs such as metformin, which are not only effective, but also available in much cheaper generic varieties. Considering the potential pitfalls in this new class of drugs, many have questioned whether Invokana is even needed.
As endocrinologist David M. Nathan, professor of medicine at Harvard Medical School put it: “I do remain generally concerned regarding this flooding of the market with diabetes drugs that really are not substantially better, and in some ways worse, than the older, less expensive, generic drugs that are available.”

Who Makes Invokana?

The drug, the first of its kind to be approved by the FDA for any use, was developed by Japanese pharmaceutical company Mitsubishi Tanabe Pharma and marketed by Janssen, a division of the multinational corporation Johnson & Johnson.

Invokana rapidly began to generate large amounts of money for the producing and marketing companies. It was estimated to bring in $111 million its first year, and analysts estimate that by 2016 it will generate around $667 million in sales.

Invokana marketer Johnson & Johnson, which had worldwide sales over $65 billion in 2011, is not new to problems of corporate responsibility. When a J&J subsidiary marketed a new variety of hip replacement in the late 2000s, it advertised “99.2% survivorship,” a far cry from its own internal statistics showing the hip replacement would fail in about 37% of patients in fewer than five years, requiring a painful and expensive operation to remove and replace the device. It took the company four years from the initial reports of trouble to recall the product. In the meantime, doctors had already placed them in 93,000 patients.

Frequently Asked Questions

Is there a legal remedy?

Yes. Hundreds of Invokana users and their families are beginning to file lawsuits against the drug manufacturers.

In similar lawsuits, drug companies have been tried for:

  • Failure to warn of risks associated with their drug, sometimes even to the point of hiding unfavorable research results
  • Negligence to adequately investigate the dangers of the drug before releasing it to the public and/or to respond adequately once dangers came to light.
  • Manufacturing a defective drug
  • Misrepresenting the drug’s risk and benefits

Since there is a time limit for those filing a lawsuit (known as the statute of limitations), it’s crucial to get professional legal advice quickly if you feel you or a loved one were injured by Invokana.

Do you qualify for compensation?

You may qualify to seek compensation if you have experienced any of the following symptoms after taking Invokana:

  • Diabetic ketoacidosis (with symptoms including nausea and vomiting, abdominal pain, weakness, shortness of breath, and confusion)
  • Major cardiac event (such as heart attack or stroke), especially if suffered in the first month of using Invokana.
  • Kidney failure

Many who have suffered these complications had to undergo extensive medical treatment, including extended stays in the hospital and follow-up treatments.

What kind of compensation can be sought?

Victims may qualify for compensation to cover a variety of expenses, including:

  • Past, present, and future medical bills
  • Loss of income
  • Loss of future productivity
  • Emotional suffering
  • Psychological distress
  • Legal expenses

Since Invokana cases are in the earliest stages of information-gathering, there’s no estimate yet on how much money could be made available for compensation.
Family members of deceased Invokana users can also file a claim for compensation. In addition to what’s cited above, this may include loss of consortium, loss of companionship, and funerary expenses.
Sometimes, judges or juries also award punitive damages, which are intended to punish companies who harm patients and deter them and others from medical fraud in the future.
