Invokana and Other SGLT2 Lawsuits

SGLT2 inhibitor lawsuits claim the Type 2 diabetes drugs caused diabetic ketoacidosis and kidney injury. Although the majority of lawsuits involve Invokana, plaintiffs also filed lawsuits after taking other SGLT2 inhibitors such as Farxiga. Plaintiffs claim drug companies manufactured faulty drugs and failed to warn them of risks. More than 770 lawsuits are pending in federal court, and lawyers continue to accept new cases.

Free Case Review

Plaintiff's attorneys argue that manufacturers of Invokana (canagliflozin) and other SGLT2 inhibitors drugs for Type 2 diabetes did not properly warn patients and doctors of the risks of serious and potentially fatal side effects. If doctors or patients had known, they might have chosen another medication or monitored their health for symptoms of complications.

Invokana users filed the first lawsuits, and then lawsuits for other drugs followed. According to lawsuits, manufacturers concealed — and continue to conceal — knowledge of SGLT2 drugs' "unreasonably dangerous risks" from consumers and the medical community. These dangerous risks include diabetic ketoacidosis, blood infections and kidney problems.

The U.S. Judicial Panel on Multidistrict Litigation (JPML) ordered Invokana cases consolidated in multidistrict litigation (MDL) number 2750 in New Jersey before Judge Brian R. Martinotti. U.S. District Judge Lorna G. Schofield is overseeing a Farxiga MDL.

The litigation is still in its early stages, and there are no settlements or jury verdicts. Discovery is still underway and no exact bellwether trial dates are set. Lawyers expect many more plaintiffs to join the MDLs. A total of 770 cases were filed under the Invokana MDL. More than 741 remained pending as of September 2017. The Farxiga MDL includes 37 cases. Attorneys are accepting cases for all SGLT2 drugs.

SGLT2 inhibitors include:

  • Invokana (canagliflozin), Janssen Pharmaceuticals, a subsidiary of Johnson & Johnson
  • Invokamet (canagliflozin and metformin), Janssen Pharmaceuticals
  • Invokamet XR (canagliflozin and metformin extended release), Janssen Pharmaceuticals
  • Farxiga (dapagliflozin), AstraZeneca
  • Xigduo XR (dapagliflozin and metformin extended-release), AstraZeneca
  • Jardiance (empagliflozin), Boehringer Ingelheim and Eli Lilly
  • Glyxambi (empagliflozin and linagliptin), Boehringer Ingelheim and Eli Lilly
  • Synjardy (empagliflozin and metformin), Boehringer Ingelheim and Eli Lilly

Side Effects Claimed in Lawsuits

Since the U.S. Food and Drug Administration approved the first drug in the class — Invokana — in 2013, it has issued a number of safety communications about these medications.

Manufacturers knew or should have known these drugs could cause potential side effects, according to lawsuits. But the first warnings did not reach the public until December 4, 2015 when the FDA required companies to put warnings on labels.

In the meantime, millions of patients received prescriptions for these drugs and may have suffered severe health problems linked to the medications.

A number of serious health problems are at the center of SGLT2 litigation. In many cases, patients were in critical condition that required hospitalization. Some plaintiffs died from their injuries. Damages claimed include past and future medical bills, pain, suffering, lost wages and funeral expenses.

Lawsuits against SGLT2 manufacturers claim the following injuries:

  • Diabetic ketoacidosis requiring hospitalization
  • Diabetic ketoacidosis resulting in death
  • Renal failure in those with no history of underlying kidney problems
  • Acute kidney injury requiring hospitalization in those with no history of underlying kidney problems
  • Stroke or other thromboembolic events
  • Urinary tract infections resulting in blood infections (urosepsis), requiring hospitalization
  • Urinary tract infections resulting in kidney infections (pyelonephritis), requiring hospitalization

Important Dates for Specific Injuries and Filing Lawsuits

In general, people who took one or more SGLT2 drugs and suffered diabetic ketoacidosis, urosepsis and pyelonephritis before December 4, 2015 may have possible claims against drug manufacturers. This is the date the FDA added the official warning for these conditions to drug labels.

Plaintiffs who suffered renal failure, acute kidney injury, a stroke or thromboembolic events before or after December 4, 2015 may still file a claim.

For statute of limitations information or other important deadlines, claimants should contact and attorney immediately to avoid possible disqualification of a claim.

SGLT2 Inhibitor Lawsuits

Plaintiffs who took Invokana, Farxiga and other SGLT2 inhibitors claim the drugs caused several severe side effects, some fatal. According to lawsuits, manufacturers “negligently, recklessly and carelessly marketed, distributed [SGLT2 drugs] without adequate instructions or warning of serious side effects and unreasonably dangerous risks.”

  • Michael Cormier – Tennessee resident Michael Cormier took Farxiga and claims the drug caused him to suffer diabetic ketoacidosis after he only took it for a month. He was in critical condition in the ICU at Vanderbilt University Medical Center for about three days. Doctors told him to stop taking Farxiga. His lawsuit alleges AstraZeneca and Bristol-Myers Squibb — who worked together to sell and market Farxiga — knew that the drug increased the risk of diabetic ketoacidosis and kidney damage but did not sufficiently warn consumers or physicians of the risk.
  • Adelina Quintanilla – Texas resident Adelina Quintanilla’s lawsuit alleges Farxiga manufacturers AstraZeneca and Bristol-Myers Squibb “willfully deceived” her, her doctors and the general public about the drug’s health risks. She claims Farxiga caused her to suffer diabetic ketoacidosis and is unreasonably dangerous and defective.
  • Patricia MacMurray – Patricia MacMurray sued Janssen Pharmaceuticals, Eli Lilly and Boehringer Ingelheim after she took Invokana and Jardiance and developed diabetic ketoacidosis. She was hospitalized for seven days, part of it in intensive care. She says the dangerous drugs caused and will continue to cause her injury and damage. MacMurray said she relied on the claims made by manufacturers that Invokana was safe and effective.
  • Donna and Terry Royse – Donna Royse filed a lawsuit on behalf of her husband, Terry, after he took an unspecified SGLT2 inhibitor and suffered kidney failure, respiratory failure and death. The lawsuit against Janssen Pharmaceuticals, Eli Lilly, Boehringer Ingelheim, AstraZeneca, Bristol Myers Squibb and Mitsubishi Tanabe Pharma accuses the manufacturers of “willful and wanton conduct and/or gross negligence,” fraud and negligent design among other allegations.

Litigation Status and Claims against Manufacturers

As of September 15, 2017, over 700 cases are involved in the Invokana MDL. The cases are before U.S. District Judge Brian R. Martinotti in the Invokana New Jersey MDL. The first bellwether trial is planned for September 2018. In addition, Invokana cases pending in the Eastern District of Pennsylvania will transfer to New Jersey.

Martinotti plans to schedule the first Invokana bellwether trial for September 2018. In the meantime, cases will be in discovery. In the discovery phase both sides exchange information and conduct depositions.

Some of the claims made against SGLT2 manufacturers include:

  • Failure to warn of risks
  • Negligence
  • Manufacturing a defective drug
  • Deceptive advertising
  • Failure to adequately test drugs
  • Misleading physicians and the public by downplaying risks
  • Willfully deceiving the public

Other Type 2 Diabetes Drug Settlements

While no SGLT2 drug lawsuits have reached settlement or jury trial yet, these are not the first class-related Type 2 diabetes drugs involved in lawsuits. Other drugs involved in lawsuits include Takeda’s Actos (pioglitazone) and GlaxoSmithKline’s Avandia (rosiglitazone) — both members of the thiazolidinedione (TZD) class.

After studies linked Actos to an increased risk of bladder cancer, lawsuits against Takeda ramped up. Tens of thousands of plaintiffs came forward claiming the drug gave them bladder cancer.

In April 2014, a jury ordered Takeda and Eli Lilly to pay $9 billion to one man who claimed the drug gave him bladder cancer. In 2015, Takeda agreed to pay about $2.37 billion to settle about 9,000 cases.

Patients who took GlaxoSmithKline’s Avandia claimed the drug caused cardiovascular death, liver toxicity and bone fractures. Since 2007, the drug was implicated in more than 50,000 lawsuits. It settled several thousand cases for just under $1 billion from 2010 to 2011. Then, the company set aside about $3.4 billion for future Avandia settlements and litigation.
