Xeljanz Blood Clot Lawsuits

PfizerIt was recently discovered that the popular arthritis drug Xeljanz may cause serious and potential blood clots in some users. This was not initially disclosed as a side effect of the drug so the drug manufacturer is now facing a growing number of product liability lawsuits. Our lawyers are currently accepting new cases from people who took Xeljanz and had any of the following health events:

  • Pulmonary Embolism
  • Stroke
  • Deep Vein Thrombosis
  • Other types of blood clot injury
About Xeljanz

Xeljanz (tofacitinib) was first approved and released in 2012 by pharmaceutical giant Pfizer. Xeljanz was a groundbreaking new type of drug called a JAK inhibitor which has a unique internal effect on certain types of cells.

Xeljanz is similar in many ways to a biologic. But this drug is really a new subcategory of disease-modifying antirheumatic drugs (DMARD) called "JAK inhibitors." Xelijanz that block Janus kinase (JAK) pathways that are involved in our immune responses. These agents target specific steps in the process. So, in theory, these drugs don't wipe out the entire immune response as do some other RA treatments

The drug is primarily used for the treatment of very severe cases of rheumatoid arthritis. However, since about 2017 Xeljanz has also been used to treat ulcerative colitis and psoriatic arthritis. Pfizer aggressively marketed Xeljanz and quickly became one of the company's blockbuster drugs because it really was working as intended if you set aside the risks. Xeljanz is now one of the most heavily-marketed and profitable drugs in history. Pfizer has reaped billions of dollars in sales from Xeljanz. In fact, Pfizer reported $1.77 billion in worldwide Xeljanz sales for 2017-2018. This is big money, the kind of drug a pharmaceutical company desperately wants to keep in the market.

Normal approved dose levels for Xeljanz are 5mg and 10mg twice a day. To prevent arthritis inflammation, Xeljanz has to essentially block or suppress a user's natural immune system responses. As a result, the drug always had a long list of potentially serious side-effects. However, blood clots were never originally listed as a potential side effect of the drug.

Xeljanz and Blood Clots

As part of the initial FDA approval for Xeljanz back in 2012, Pfzier was required to conduct a long-term post market research study. The aim of this post-approval study was to evaluate the potential risks of cardiovascular problems resulting from use of the drug. The initial results of this long-term study were provided to the FDA at the beginning of 2019 and they caused major concerns. Specifically, the study found that the higher Xeljanz dose (10mg twice daily) appeared to cause life threatening blood clots in some patients.

In response to these study results, the FDA issued a safety announcement and Pfzier was required to add a "black box warning" (the most serious type of drug label warning) about the risk of blood clot deaths at higher doses. The higher, 10mg dose of Xeljanz is no longer approved for the treatment of arthritis because the risk of blood clots is considered too high.

Xeljanz Lawsuits

Pfzier is now facing a rapidly growing number of lawsuits by users of Xeljanz who suffered blood clots or similar injuries. All pharmaceutical companies have a duty to fully and appropriate research the safety of their drugs before they are approved and released. This is particularly true with completely new types of drugs such as Xeljanz. Drug companies also have a legal duty to warn about any potential risks, side effects, or health concerns associated with their drug. This is information is often critical because it enables doctors to make informed decisions about drug safety for individual patients.

Xeljanz lawsuits against Pfzier are alleging that the company breached its duties to the public in several ways:

  • Pfzier negligently failed to conduct adequate safety research and testing before getting approval for Xeljanz.
  • Pfzier new that the higher dose of Xeljanz caused blood clots and other problems, but failed to disclose this information.
  • Pfzier failed to warn that higher doses of Xeljanz may cause blood clots and cardiovascular problems.

Most of these allegations appear to be fairly valid and Pfzier will likely be facing serious liability in these cases. The warnings about Xeljanz and blood clots are fairly recent, so not many lawsuits have been filed against Pfzier at this point. Over the next year, however, Pfzier will likely be named in hundreds of Xeljanz lawsuits across the country.

Can You File a Xeljanz Lawsuit?

InfographicSeveral hundred thousand people in the U.S. were taking Xeljanz to treat their arthritis. Only a certain percentage of these Xeljanz users will actually have a valid lawsuit against Pfzier.

To qualify as a potential Xeljanz plaintiff you will need to satisfy at least the following 3 requirements:

  1. You were taking Xeljanz or Xeljanz XR for treatment of arthritis for a minimum of 6 months.
  2. You were taking the higher Xeljanz dose - 10mg twice a day.
  3. You suffered a pulmonary embolism, deep vein thrombosis, stroke or other blood clot related injury while taking Xeljanz.

If you (or a deceased family member) satisfies all 3 of these conditions, you may be entitled to file a lawsuit against Pfzier.

Value of Xeljanz Cases

If you have a potential Xeljanz lawsuit, it is only natural to wonder how much money your case might potentially be worth. The potential settlement value of individual Xeljanz cases will vary based on a number of factors. The most significant factor in determining settlement value (or trial value) will be the extent of the victim's injuries. Some people who suffer blood clots from Xeljanz may only end up with a stay in the hospital and few days of stress and discomfort. Others may be left permanently paralyzed, partially disabled, unable to talk or dead. Plaintiff with more serious permanent injuries from Xeljanz will have higher value claims.

In the context of medical malpractice cases, however, the settlement value for pulmonary embolisms and similar blood clot injuries tends to be fairly high. This is because these type of events often have catastrophic consequences such as death or limb amputation.
