What Is Xeljanz? How Can My Firm Attract Xeljanz Victims?

Did Pfizer Hide The Fact That Xeljanz Could Cause Septic Shock With Patients In The US? 

xeljanzThe U.S. pharmaceutical industry sells countless innovative products like Xeljanz every day. Some products prove to contain carcinogenic properties or cause harmful side effects following ingestion.

Litigation is often consumers’ course of action when manufacturers withhold that dangerous information from doctors and consumers.

Xeljanz by Pfizer is a product currently facing under scrutiny by the courts. Doctors prescribe this drug to treat rheumatoid arthritis (RA), psoriatic arthritis or ulcerative colitis.

Qualifying plaintiffs took Xeljanz and later suffered from blood clots in the legs, thighs, pelvis, or lungs. 

History of Xeljanz 

Pfizer developed and manufactured Xeljanz. Pfizer’s revenues amounted to $51.8 billion in 2019. The company also reported that it made $1.7 billion from Xeljanz in 2018

Xeljanz (tofacitinib) is a member of a family of biologic drugs called Janus kinase (JAK) inhibitors. Biologic drugs are not made from chemicals. They are made from living animal, human, or bacterial cells. JAK inhibitors suppress the body’s immune system in order to prevent pain and swelling. They also prevent damage to the joints from RA and psoriatic arthritis. 

When a patient has RA, the body produces too many cytokines which are part of the body’s inflammation response. JAK inhibitors block proteins that pass signals along the pathway between immune system components. Thus, blocking these proteins calms the immune response and reduces RA symptoms. 

Some patients’ symptoms are controlled by adalimumab or methotrexate. As a result, they do not need JAK inhibitors. Patients who don’t get relief from this older class of drugs often experience less severe symptoms when taking JAK inhibitors.

Repercussions of Fooling the Immune System

However, the most prevalent negative side effect of JAK inhibitors is that suppressing the immune system opens the door to opportunistic disease. As a result, patients are more likely to suffer from viruses like such as shingles. They could also develop serious bacterial lung infections and tuberculosis (TB). Therefore, JAK inhibitors have a short lifespan which means after a patient stops taking them, the body returns to its normal infection-fighting state. 

Side effects of Xeljanz include: 

  • Blurry vision 
  • Body aches  
  • Coughing up blood 
  • Difficulty urinating 
  • Fever 
  • Headache 
  • Swelling of face, arms and legs 
  • Chest pain 
  • Dark urine 
  • Welts 
  • Burning feeling in chest 
  • Itching, crawling, tingling feelings 
  • Difficulty moving 
  • Tenderness in stomach 

Xeljanz Enters the Marketplace  

The U.S. Food and Drug Administration (FDA) approved Xeljanz for introduction into the market on November 6, 2012. The FDA approved Xeljanz as a treatment for moderate to severe RA. Doctors prescribed the drug to 130,000 patients in America between 2013 and 2018. the FDA approved the drug for other conditions in December 2017 for psoriatic arthritis and ulcerative colitis. 

Between 2013 and 2018, the FDA received patient notices of 52 deep vein thrombosis (DVT) blood clots and 79 lung (Pulmonary Embolism, or PE) blood clots presenting in patients taking Xeljanz. Of those cases, 15 patients died. 

FDA Warnings About Xeljanz

In February 2019, the FDA issued an alert to consumers and a black box warning requirement on the drug’s package insert. Consequently, the insert stated that Xeljanz increases the risk of blood clots and death. That same month, Pfizer issued a press release reducing the recommended Xeljanz dosage to half (from 10 mg twice daily to 5 mg twice daily) as a result of the post-market study of RA patients taking Xeljanz. 

In July 2019, the FDA issued another black box alert with respect to consumers who take Xeljanz. The FDA warned patients over 50 years old and have cardiovascular risks. The agency also concluded that people who take the drug for ulcerative colitis are in danger of potential blood clots or death.  

On February 4, 2021, the FDA also issued another warning to consumers. The warning stated that clinical studies showed Xeljanz increases the risk for serious heart problems and cancer. The study results apply to both arthritis patients and ulcerative colitis patients. The warning also applies to both 5 mg and 10 mg dosages. 

Litigation to Date 

To qualify as a Xeljanz lawsuit plaintiff, patients must prove that: 

  • Doctors prescribed them Xeljanz to treat their arthritis on the basis of medical and pharmacy records 
  • The prescribed dose was 10 mg twice daily 
  • They suffered a deep vein thrombosis (DVT blood clot), a Pulmonary Embolism (lung blood clot), stroke or similar blood clot injury 

At this time, Xeljanz lawsuits are currently moving through the legal system on an individual basis. They seek: 

  • Medical expenses 
  • Lost wages, reduced earning capacity 
  • Pain and suffering 
  • Loss of consortium 

In July 2019, an Arkansas woman, Marilyn Stube, filed a lawsuit against Pfizer claiming that she took Xeljanz for arthritis and the drug subsequently caused her to develop sepsis. After taking the drug for four years, her medical team treated her for septic shock and multiple organ failure. In addition they treated her for gangrene and a strep infection. The sepsis led to amputation of all four of her limbs.  

The lawsuit claims that Pfizer knew of the risks to patients from Xeljanz and failed to warn doctors. Xeljanz packages sold in Canada, Australia and the European Union (EU) contain warnings about sepsis. However, the lawsuit charges that Pfizer did not follow its own procedure. The lawsuit also states Pfizer omitted the sepsis data from its clinical trials and failed to notify the FDA of the adverse reactions to the drug. 

Potentially thousands of plaintiffs exist in the U.S. and worldwide due to the popularity of Xeljanz. To date, no cases have been consolidated into multi-district litigation (MDL), and no plaintiffs have filed class action lawsuits—individual lawsuits prevail at the moment. If lawyers identify enough injured parties, future MDL or class action lawsuits are a possibility.
