Potential Invokana Class Action Settlements

The FDA has recently expressed concern about a certain group of medications called SGLT2 Inhibitors. This category of drugs includes popular prescription medications such as Invokana and Farxiga. Although these drugs have been, by all accounts, fairly successful when treating Type 2 diabetes. But,  they have produced their fair share of side-effects. Specifically, users of drugs such as Invokana are now reporting high levels of blood acid, the effects of which have landed some users in the ER.  While no deaths have been reported, there is no question that if these reports are accurate, these levels of blood acid could cause serious injury and death.  Accordingly, plaintiffs’ lawyers are investigating whether there is a connection between these drugs and these high acid levels and, if so, whether these drug makers knew about these risks and simply failed to inform patients and doctors.   If these dots are connected – and there is reason to think they might be – there are likely to be both serious injuries and lawsuits seeking compensation for those injuries.

SGLT2 Inhibitors

Invokana and Farxiga fall under an umbrella of a relatively new class of medications referred to as SGLT2 Inhibitors. The FDA considers this a fairly novel group of drugs and has only approved two medications within the class: Canagliflozin (Invokana) and Dapagliflozin (Farxiga). Both drugs are intended to treat Type 2 diabetes by inhibiting the amount of glucose that is absorbed in the bloodstream.

Someone with Type 2 diabetes typically produces and transports more glucose in their blood than a person who does not have diabetes. This prevents glucose from being excreted from the body as easily as it should, resulting in hyperglycemia (high-blood sugar levels). SGLT2 Inhibitors work to ensure that the proper amount of glucose is excreted from the body, thus stabilizing blood sugar levels. Invokana was one of the first SGLT2 inhibitors to be approved by the FDA back in March of 2013, with Farxiga receiving approval approximately one year later. As with many diabetes treatments, diet and exercise are recommended to reap the full benefits of the drug.

Side Effects

After use of the drug became more widespread, some users of Invokana began to experience ketoacidosis. This condition is essentially a buildup of acid in the blood, which can lead to serious complications. Generally, people with Type 1 Diabetes are at highest risk of ketoacidosis because their bodies do not produce insulin. As is such, the body uses fat cells as opposed to glucose for energy to make up for the lack of insulin. This process produces ketones, which also build up when the body is sick, stressed, or if you miss a meal. In the end, an excess of ketones can disrupt the body’s entire chemical balance, leading to symptoms such as: vomiting, nausea, confusion, fatigue, abdominal pain, and difficulty breathing.

On May 5, 2015, the FDA officially issued a warning regarding this potentially fatal side-effect of SGLT2 Inhibitors. The warning noted that around 20 cases of acidosis or ketoacidosis were identified by the FDA, all of which required the patients to seek emergency medical attention. While no deaths have been reported from the use of SGLT2 Inhibitors, untreated ketoacidosis can lead to coma and even death. This is why it is so crucial for people on drugs such as Invokana and Farxiga to go to the emergency room in the event that they experience any of the side effects listed above.

The FDA is nt the only group concerned about this drug either. The Institute for Safe Medication Practices shed some light on a number of side-effects that were associated with Invokana. Most of them involved potential kidney issues such as: kidney failure and impairment; severe dehydration; kidney stones; and urinary tract infections. But serious allergic reactions were also reported. The utility of this drug is really starting to be questioned, especially considering that clinical trials showed that people on the drug have a higher risk of developing fungal infection as well. Bear in mind, this does not even take into account the long-term animal tests that showed a correlation between the medication in Invokana and certain types of cancer. Some lawyers are also exploring a connection between heart attacks and these drugs.

Invokana Lawsuits

Just because a drug causes harmful side-effects does not mean that everyone affected by those side-effects has a legal claim against the manufacturer. Typically, when a drug manufacturer is sued, it is because they failed to warn or tried to conceal the hidden dangers behind their drug. In this instance, lawsuits are likely to allege that the manufacturer of Invokana, Janssen, failed to warn about the risks of ketoacidosis. If you think you were affected, the best course of action is to contact an attorney.

One reason for the healthy skepticism about what the drug makers knew about these possible side effect is that diabetes drugs are a ridiculously lucrative source of profits for drug companies.  So in the past we have seen drugs rushed on to the market without the internal research necessary to make sure they are safe.  Is that what happened here?  This is what we need to find out.

There are not any settlements or verdicts to report from Invokana cases just yet given how recent some of these developments are.   The settlement value of Invokana and Farxiga claims are still unknown because, as we have been saying, we do not have a complete handle on exactly what happen.  The serious injury and death cases have the potential to be very large cases. It is early; this is a very new piece of litigation.  But if you think you might have a claim, calling a lawyer now is just a good idea. Things may move quickly from here.

Little Risk in Diabetes Drugs Says European Regulators

pills2According to a recent news release, regulators in Europe have concluded that there is little evidence that widely used drugs to treat Type 2 diabetes could cause pancreatic inflammation or pancreatic cancer.

In addition to the European agency, the Food and Drug Administration has been reviewing the safety of a big class of drugs that includes Januvia by Merck and the drugs Byetta, Bydureon and Onglyza, which are sold by Bristol-Myers Squibb and AstraZeneca.  These drugs, called incretin mimetics by the FDA, increase the body’s levels of a hormone that helps to control blood sugar levels.

They have, however, been linked to pancretic inflammation known as pancreatitis.  While the European agency said that the clinical trials had shown no increased risk of pancreatic cancer,the FDA said the trials were too small to draw firm conclusions.

The recent European news is music to the ears of these diabetic drug manufactures who had more than $9 billion in global sales last year. Januvia and Janumet, also manufactured by Merck, together earned $5.7 billion.

How, Then, Do We Explain the Byetta/Januvia Lawsuits?

This is one study that goes the other way.  But it flies in the face of all of the next evidence suggesting that these drugs can cause pancreatic cancer.  Keep in mind that these were very small trials. The FDA is certainly not buying into and and they are reserving judgment.

I think this is the history of many mass tort claims:

  1. Problem becomes obvious
  2. Lawyers start filing suit, probably prematurely
  3. The science and the studies begin to follow #1
  4. There are a few rebuttal studies, usually of dubious methodology
  5. The case start going to trial
  6. The science becomes even more clear
  7. The case settle in massive numbers

I think we are on Stage #4 right now.

Update: Pfizer Opposes Lipitor MDL

Last month we told you that a group of Plaintiffs had filed a motion to consolidate all federal Lipitor diabetes lawsuits before one South Carolina judge as part of a Multi-District Litigation or MDL.  To date, at least five different Lipitor lawsuits have been filed against Pfizer in three different U.S. District Courts throughout the country. The motion indicates that numerous additional complaints are expected.

lipitorNot surprising, Pfizer has indicated that they are opposed to the formation of coordinated proceedings involving Lipitor, arguing that the litigation is not sufficient big enough to require the consolidated proceedings and that such a procedure would only result in a wave of lawsuits filed by lawyers who may not otherwise be willing to litigate claims.

Lipitor has been linked to diabetes. Lipitor prevents an enzyme in the liver from creating low density lipids (LDLs).  The drug works to prevent the production of LDLs, a type of cholesterol that blocks arteries, and reduce the user’s risk of developing heart disease. Lipitor, which generates more than $14.5 billion in combined annual sales, is among the best selling drugs in the world.

This would not be the first Lipitor MDL. U.S. District Judge Peter Sheridan presides over an MDL in New Jersey. In that case,  plaintiffs’ lawyers allege Pfizer improperly extended its patent rights on the anticholesterol drug Lipitor and then when the rights were expiring,  conspired with the a generic drug manufacturer Ranbaxy to block the generic version of the drug.  This lawsuit is a totally different animal but there is a common thread to both cases: allegations that Pfizer is greedy.

The U.S. JPML is expected to schedule oral arguments over the motion to consolidate the Lipitor diabetes litigation for an upcoming hearing session, scheduled for July 25, 2013.

We will continue to give you the latest updates in the Lipitor cases.  Bookmark this page.

And… if you think you have a potential Lipitor claim – particularly if you are a woman with diabetes – we will give you a free on-line case evaluation.

 

Will We Have a Lipitor Class Action Lawsuit?

Five plaintiffs last week sought an MDL for federal lawsuits against Pfizer’s Lipitor.  The allegations are the same in all cases: the cholesterol drug caused them to develop diabetes.

The gist of plaintiffs claims is that the drug increased serum glucose levels causing diabetes.  Pfizer never properly let patients or doctors know of this risk so they could make a different choice or perhaps avoid this class of drugs all together. Accordingly, the suits allege, Lipitor is defective and unreasonably dangerous and the drug was sold with a warning that did not properly alert patients and doctors of the risk.

Not for nothing, Pfizer has been making money had over fist with Pfizer.  If you have help Pfizer stock in the last few years, you have gotten pretty rich in no small part due to Lipitor.

The MDL would create a “sort of” class action where all of the cases would be consolidated in federal court.  The plaintiffs have suggested the case be centralized in South Carolina.

There have been a number of mass tort “the drug caused me diabetes” cases that have failed.  With Lipitor be different?  Let’s see.

Lipitor Diabetes Lawsuits

Almost all prescription drugs carry the potential for side effects.  Some of these are minor, others significant.  Recent data suggests that Lipitor, the popular cholesterol drug, is strongly correlated with increased rates of Type 2 diabetes.

Lipitor (atorvastatin calcium), made by Pfizer, is a statin.  Statins reduce cholesterol by blocking specific liver enzymes.  By blocking these cholesterol-producing enzymes, the body begins to use cholesterol already in the blood.  This process lowers overall cholesterol levels as well as the risk of heart disease and heart attacks.

One problematic and newly discovered side effect of Lipitor is the increased potential for developing Type 2 diabetes.  Just last year the FDA mandated a change to Lipitor’s warning label.  The new label specifically tells users of the threat of diabetes.  Other statins, like Zocor and Crestor, were also required to make similar label changes.

Although statins have been in use since the 1980s, it was not until the past ten years when long-term data was analyzed to find the Type-2 diabetes correlation.  Researchers are not certain why statins are correlated with higher diabetes rates.  One potential explanation is that statins increase blood sugar levels.

Lipitor is one of the stronger statins on the market today.  High strength statins carry the increased risk for diabetes, whereas weaker statins generally do not.  Drugs like Lipitor become particularly risky when used in high doses.  Multiple studies have confirmed that when strong statins are used in a high dose manner the risk for diabetes greatly increases.  The bottom line with these drugs is that the ideal dosage has not been established.

More than 20 million Americans currently take statins.  If the studies are correct and about one out of every 200 statin users will develop diabetes, this means that 100,000 more people will develop diabetes than would otherwise do so.

Adding to this risky equation is the fact that millions of statin users take them preventatively.  In fact, some studies have found that in these users, the heart attack and heart disease reduction rate is only 2 per 100.  So if all this data is to be believed, out of every 200 statin users, four will be benefitted and one will develop diabetes.

Getting the full picture of long-term statin use will take another 20 years.  In the meantime, people taking statins needs to be aware of the very serious risks that drugs like Lipitor could pose to their overall health.

Getting a Claim Started

Will your Lipitor diabetes case be a successful lawsuit?  The answer is simple: I don’t know.  But we are now reviewing these cases and trying to figure out whether they may be viable claims.  Certainly, it is fair to say that women have much better claims than men do for a variety of reasons.   If you want your Lipitor diabetes case evaluated, contact us here.

Januvia, Byetta, and Pancreatic Cancer

Type-2 diabetes is the most prevalent form of diabetes in America. 25.8 million children and adults in the US are being treated for the condition. Each year almost 2 million more people are diagnosed. In 2012 alone, the treatment cost of type-2 diabetes in the United States was $176 billion.

Two new drugs, Januvia and Byetta, offer new ways of treating diabetes.  By all accounts, they work well in treating diabetes.  But these drugs have also been linked to increased rates of pancreatic cancer.

The Theory That Links Januvia and Byetta and Pancreatic Cancer

These drugs behave differently than older pharmaceuticals, so here’s a quick breakdown of the science behind each treatment. Type-2 diabetes is caused by hyperglycemia in the context of inadequate insulin secretion and insulin resistance.

These new drugs treat type-2 diabetes by using the gut hormone glucagon-like peptide 1 (GLP-1). This hormone is naturally secreted by endocrine cells in response to eating food and it increases glucose-medicated insulin secretion. This means that GLP-1 tells the pancreas to make insulin. During this process, the hormone is degraded by the enzyme dipeptidyl peptidase-4 (DPP-4). Januvia and Byetta treat diabetes by sustaining GLP-1 receptor activation. Byetta, an injectable drug, does this by being a GLP-1 agonist that resists DPP-4 degradation. Januvia (sitagliptin), an oral drug, uses inhibitors of DPP-4 to enhance the levels of endogenously secreted GLP-1. So essentially these drugs get to the same problem by starting at different ends; Byetta adds chemicals that act like GLP-1 and Januvia inhibits the DPP-4, which degrades the natural GLP-1.

Recent studies have confirmed that drugs that act like GLP-1 inflame the pancreas. By spiking hormone levels, the drugs change the normal GLP-1 pathway to the pancreas and also speed up the creation of the cells that line the pancreatic duct.

The problem is that researchers also believe that pancreatic cancer usually starts in those exact duct and islet cells. One UCLA study referenced FDA statistics to observe a six-fold increase in cases of pancreatitis in Byetta and Januvia users.   Let’s say those numbers are inflated a little.  There are still unbelievable and they still underscore what these drugs are doing to the pancreas.  Additionally, the study also found a 2.9-fold increase in pancreatic cancer in those using Byetta and a 2.7-fold increase in pancreatic cancers for those using Januvia. Both drugs are also linked to increased rates of thyroid cancer but not other cancers generally.

These findings are likely due to the fact that diabetes drugs are used for long periods of time. Type-2 diabetes does not have a cure thus patients can be on a single treatment for decades. If patients were using Byetta or Januvia for a short period of time, it is likely that the pancreatic cancer correlation would not persist because the duct cells would not be over-stimulated every day.

The makers of Byetta One possible mitigating explanation for these health correlations is the fact that a high percentage of people with type-2 diabetes also suffer from being overweight. Being obese or overweight is directly linked with pancreatic cancer. For patients with a family history of pancreatic cancer, insulin and metformin could be safer alternative treatments. In fact, researchers have found that using Januvia when taking metformin removes the threat of increased pancreatitis. The link between weight and pancreatic cancer doesn’t eliminate the risks these drugs can pose, rather it is one part of the equation.

First Actos Trial

Asia’s biggest drugmarker, Takeda Pharmaceutical Co., is facing its first trial of lawsuits involving Actos. Alleged to have caused cancer in some patients, Actos was once the world’s biggest-selling diabetes drug. Like many diabetes drugs that were pushed on the market as the drug companies chased a gold rush of profits, lawsuits ensued. Now Takeda faces more than 3,000 lawsuits alleging Actos caused bladder cancer or other ailments among patients.

More than 1,200 suits have been consolidated before a federal judge in Louisiana for pretrial information exchanges. The first federal case is set for trial in November 2014. In the meantime, Takeda faces its first case today in state court in Los Angeles. Plaintiff is a 69 year old man who took Actos for more than two years. Diagnosed with bladder cancer in November 2011, he is “gravely ill” according to the Judge that granted an expedited trial of his claim.

This trial comes one month after Japanese-based Takeda won U.S. regulatory approval for Nesina, a new diabetes drug to replace Actos.

Actos Settlements on the Horizon?

What issues Nesina may bring remains to be seen. The newer diabetes drugs have just not been better. But, if you think this is a harbinger of Actos settlements, I’m inclined to agree. Before they settle cases in massive numbers, they need to first get their next drug ready to go so they can keep the profits rolling. It is a sad commentary but it happens all of the time.

Jury Verdict: Turning of Tide in Fosamax Cases?

I wrote last week about how nothing is going right in the Fosamax cases. Now something did go right. A jury in New York yesterday awarded $285,000 to a plaintiff for Novartis on the defective design case. Which is fine, really. You only need one reason to win.

Is $285,000 a huge victory in a piece of litigation where some of the injuries are so utterly awful? No. But after a string of losses, a win is a win. Could this be the turning of the tide in these cases? I think Novartis is probably going to bet no and keep on trying these cases. We will see.

Blow to Fosamax Cases

In a blow to all Fosamax plaintiffs, but one in particular, the 2nd Circuit Court of Appeals upheld a defense verdict for Merck on Wednesday, finding no errors in the lower court’s rulings.

At particular issue was the trial court’s exclusion of plaintff’s key experts. The 2nd Circuit said that one of the experts offered irrelevant testimony that was properly excluded, and that the trial court correctly ruled that the expert could not give testimony about the competency of the FDA because the expert lacked the qualifications to do so. As for another expert (awkward writing because I hate using names when I don’t have to, sorry), the court found that the expert’s causation opinion was properly excluded because it was offered in his capacity as a treating doctor.

How does this make sense? Well, Florida law requires plaintiff to show that the treating doctor would have recommended that she stop taking Fosamax if they had known about the risks. Here, the treating doctor did not know she was taking Fosamax during the relevant time period.

What is the settlement value of the remaining Fosamax cases? A lot less than I originally thought they would be and even less after this verdict. Can the cases be turned around? Absolutely? But right now, if you had a graph of the expected average settlement value of Fosamax cases, I think you would see a downward slope. I’d like to be proven wrong.
