What is Invokana?
Invokana is a relatively new drug that is aimed at acting as a SGLT-2 inhibitor. The drug is taken orally as opposed to being injected. The way that the drug works is by inhibiting a certain kind of sodium glucose co-transporter. This transporter actually works to facilitate absorption of glucose into the kidneys. By going after the transporter, this forces glucose to be eliminated in the urine as opposed to going into the bloodstream. The end result should be a reduction in blood sugar levels.
Invokana consists only of canagliflozin. Invokamet adds metoformin to make for a combined medication. Metformin is another medication that is used to treat diabetes. It is intended to help make it easier for insulin to cause a reaction in cells. By taking Invokamet, patients alleviate the need to have to take two different pills by combining them in one medication.
Who Makes Invokana?
Invokana is manufactured by Janssen Pharmaceuticals, Inc. Janssen is a subsidiary of the pharmaceutical giant Johnson & Johnson. Invokana was approved by the FDA to treat type-2 diabetes in 2013. Around the same time, an application for FDA by Bristol, Myers Squibb for a similar drug to treat diabetes was initially rejected before it was approved.
Invokana has seen brisk sales since it received its FDA approval. The product had gained wide acceptance in the marketplace as one of the first of its kind of medications. However, as news of hazardous side effects of Invokana have emerged, sales have slumped and competitors have gained ground. In fact, sales have been falling as bad news has come out about Invokana.
Invokana Side Effects
As mentioned above, it has emerged that there are some severe Invokana side effects that have resulted from the use of Invokana. There are several major areas of damage that have been caused by Invokana. The drug is known to cause damage to kidneys. Several patients have allegedly died from kidney damage caused by Invokana. In addition, use of Invokana has been connected to ketoacidosis. This occurs when one’s body produces too many ketones. This is a harmful blood acid that occurs when the body cannot produce sufficient insulin. Ketoacidosis is treatable if it is caught in time, but it often requires hospitalization. Another complication of Invokana is that is has been alleged to cause heart disease in patients. Invokana side effects are serious matters that must be carefully researched by victims
The most major invokana side effects and complication that has resulted from Invokana is an increased risk of amputations in patients. Diabetics already face a heightened chance that they will require an amputation. Many of the amputations allegedly caused by Invokana have been to the foot. Some doctors have speculated that the effect of Invokana is that it causes blood to pool in the foot. Others have surmised that Invokana decreases the fluid that flows through the bloodstream, exacerbating the already poor circulation of those with diabetes.
As the side effects emerged, the FDA did further investigation. As a result of the FDA investigation, box label warnings were required that called attention to the increased risk of amputation. In addition, the FDA recently issued a new warning in the face of a spate of infections that have been caused by Invokana. Although Johnson & Johnson has hotly contested the finding that Invokana can lead to amputation, sales of Invokana have lost ground.
The Invokana Lawsuits
There have been a multitude of invokana side effects lawsuits that have been filed against Johnson & Johnson in the wake of the news about Invokana. By early 2018, there were approximately 1,100 lawsuits pending related to side effects of Invokana. The lawsuits have alleged that Invokana is a defective product due to the side effects that it causes. The defect has been alleged to be a manufacturing. Alternatively, plaintiffs have described the defect as a design defect. The complaints allege that Johnson & Johnson failed to perform adequate testing before marketing the product to the public. Additionally, the suits claim that there was a more economical alternative available that would not have had the defects.
The plaintiffs have alleged that Johnson & Johnson has known about the possible side effects and took action to conceal the information from the public. The manufacturer allegedly continued to market the product in spite of its knowledge that the drug is dangerous. Johnson & Johnson had a duty to warn patients of the dangers associated with Invokana and failed to do so.
Additionally, the lawsuits accuse Johnson & Johnson of breaching several warranties that should come when a consumer purchases its products. There is an express warranty that Invokana was safe and fit for use for its intended purpose to treat diabetes. Finally, the invokana lawsuits allege that the manufacturer of Invokana was negligent in its manufacture and design of Invokana.
In response to the lawsuits, Johnson & Johnson set aside an accrual as an accounting method. An accrual is a form of liability. Here, it is apparently acknowledging that Johnson & Johnson will face some sort of liability from Invokana.
Predictably, Johnson & Johnson decided to settle many of the lawsuits stemming from the Invokana side effects. There were over 1,000 cases that were pending in New Jersey as part of a multi-district litigation. These cases were are settled. The settlement amount is still confidential as of this writing. There will be a settlement fund that will be established to administer the payments to the plaintiffs. There are multiple other cases that are pending in other courts across the country. It is likely that there will eventually be settlement agreements in those cases as well.
If you have taken Invokana and have suffered some of these invokana side effects, you should immediately contact an invokana lawsuit lawyer to discuss your legal rights. You may be entitled to compensation for the invokana side effects and injuries that you have suffered.
Invokana has been marketed as an effective treatment for Type-2 diabetes. However, Invokana has been beset by safety issues and FDA warnings over the past several years, dating back to very shortly after it was approved. As a result of the myriad of complications that have been caused by the drug, the manufacturer now faces a large amount of product liability lawsuits that is growing by the day.
The developer of Invokana was Mitsubishi Tanabe Pharma. Through a licensing agreement, Janssen Pharmaceuticals is the marketer of Invokana. Janssen is a subsidiary of Johnson and Johnson. Invokana was given FDA approval to be used as a treatment for diabetes in 2013. Invokana is intended to act as a SGLT2 inhibitor which blocks certain proteins from being absorbed. Instead of being absorbed, when the medications works as intended, these proteins are eliminated through the urine.
Why does invokana cause amputations?
“Based on new data from two large clinical trials, the U.S. Food and Drug Administration (FDA) has concluded that the type 2 diabetes medicine canagliflozin (Invokana, Invokamet, Invokamet XR) causes an increased risk of leg and foot amputations. We are requiring new warnings, including our most prominent Boxed Warning, to be added to the canagliflozin drug labels to describe this risk.” FDA
“Patients taking canagliflozin should notify your health care professionals right away if you develop new pain or tenderness, sores or ulcers, or infections in your legs or feet. Talk to your health care professional if you have questions or concerns. Do not stop taking your diabetes medicine without first talking to your health care professional.” Id.
Invokana FDA warning
“Certain medications, such as Invokana, can also increase the risk of amputation. Invokana, the trade name for the drug canagliflozin, is prescribed to patients for the treatment of type 2 diabetes. The drug is licensed from Mitsubishi Tanabe Pharma Corporation to Johnson & Johnson’s Janssen Pharmaceuticals division for distribution throughout most of the world. ” https://medtruth.com/invokana-cause-amputations/
“According to Janssen Pharmaceuticals, Invokana lowers blood sugar (A1C) and the 300-mg dose is proven to reduce A1C levels more effectively than a competing drug from Merck called Januvia.” Id.
What is the reason for the FDA Invokana amputation warning?
“Known Invokana side effects include ketoacidosis, kidney problems, urinary tract infections and a higher risk of broken bones. Amputation risk, however, is a new concern for users of the popular diabetes medication.
In 2017, the U.S. Food and Drug Administration began requiring new ‘black box’ warnings to be added to Invokana labels to describe the increased risk of leg and foot amputations to patients.” Id.
“The FDA acted following two large clinical trials, CANVAS and CANVAS-R, in which the data demonstrated that leg and foot amputations occurred about twice as often in patients treated with canagliflozin compared to patients treated with a placebo.” Id.
Invokana had previously been the market leading drug in the SGLT2 inhibitor space. However, negative reports and lawsuits surrounding Invokana as well as competition from a new drug have reduced Invokana’s sales. In 2017, sales dropped by 20 percent to $1.1 billion. Sales have further fallen in the first quarter of this year. Johnson and Johnson has been seeking to expand the label for Invokana, but has faced delays from the FDA as there have been strong concerns about the safety of the drug.
Invokana has had a long history of regulatory problems as safety issues regarding the drug have mounted in recent years. Invokana has gone from being perceived as a significant advance in the treatment of diabetes to a drug that has been linked with some severe side effects. This has placed the drug under a cloud that Johnson and Johnson has found it difficult to escape.
The first issue with Invokana emerged in 2015 when it was reported that there were links between Invokana and ketoacidosis. Following that, the FDA issued a communication discussing possible links between Invokana and lower bone density and fractures. Shortly after that, the FDA required warnings that would detail connections between Invokana and bladder infections. Finally, in 2017, the FDA required a label warning that would discuss heightened risks of amputation that are faced by users of Invokana. The amputation risk has been a large driver of the drop in sales of Invokana. Although Johnson and Johnson has attempted to counter this with scientific data of its own, the label warning remains in place.
Ivokana has been the subject of a variety of lawsuits in the past several years. The major areas of causes of action have been those associated with ketoacidosis and amputations. In February 2018, Johnson and Johnson disclosed in a Securities and Exchange Commission filing that it was currently named as a defendant in approximately 1,100 lawsuits pertaining to Invokana. According to Johnson and Johnson, the number of lawsuits related to this drug continues to increase, and the company expects more lawsuits to be filed in the future. Johnson and Johnson has established an accrual for these lawsuits. Currently, the main litigation regarding Invokana is a multi-district suit that has been brought in the United States District Court for the District of New Jersey. This is where Johnson and Johnson is headquartered. There are cases pending in several other state courts as well as Canada.
The claims against Johnson and Johnson are rooted in product liability. The lawsuit alleges that Johnson and Johnson failed to adequately warn the public of the dangers associated with Invokana. Johnson and Johnson is alleged to have also marketed Invokana for off-label purposes such as weight loss, reduced blood pressure and Type-1 diabetes. According to the complaint, not only did Johnson and Johnson fail to warn of the dangers, but it willfully misrepresented these risks to consumers.
According to the complaint, Johnson and Johnson knew or should have known of these risks based on data that they possessed. Even if Johnson and Johnson did not have this data, they had the ability to obtain this data through proper testing of the drug or through other efforts to learn about the side effects. The complaint alleges that, even after Johnson and Johnson learned of the increased risks of the drug, it continue to defend the drug to the public and to doctors. According to the plaintiffs, the failure to warn of the dangers makes Johnson and Johnson strictly liable.
In addition, the lawsuits allege that Invokana was defectively designed. The fact that Invokana caused these side effects made it defective at the time of its design and manufacture. According to the complaint, the design defect outweighed any benefits that could be obtained from the medication. In addition, the plaintiffs have alleged that the defendants were negligent in the design on the medication. Finally, plaintiffs have stated that Johnson and Johnson breached express and implied warranties associated with the drug.
The most serious accusation contained in these lawsuits is that the defendants fraudulently misrepresented the safety of Invokana. Johnson and Johnson is alleged to have intentionally omitted these side effects when it had a section in the drug user guide that specifically asked about possible side effects. Johnson and Johnson should have warned consumers that Invokana was more dangerous than other diabetes drugs due to the potential side effects about which it knew or should have known.
Currently, these cases are pending in front of the courts. In order to reduce duplicative discovery requests, these cases have been consolidated into a multi-district lawsuit. This is not the same as a class action suit since the plaintiffs can still receive individualized compensation if they prevail. There have been no settlements reached and no decisions issued in the case. Currently, Johnson and Johnson is still contesting liability in this case.
If you have been taking Invokana and believe that you have suffered harm, you should immediately consult with an Invokana lawsuit attorney regarding your legal options. Due to the statute of limitations, potential plaintiffs have a limited amount of time in which they can file an invokana amputation lawsuit and still obtain relief. An invokana lawsuit is a very serious matter and you need representation from the best invokana lawsuits law firm.
