Do You Take Tasigna to Treat Leukemia? You Could Be at Risk for Atherosclerosis—and the Manufacturer May Not Want You to Know

If you have a specific type of leukemia—Philadelphia chromosome-positive chronic myeloid leukemia, or Ph+ CML—you may have been prescribed the chemotherapy drug Tasigna (nilotinib). Tasigna offers promise for some patients and may even be associated with remission of their disease—but it’s not without risks.

What’s more alarming, the drug’s manufacturer, Novartis Pharmaceuticals Corporation, may have known about those risks and failed to disclose them to you. People who have been harmed or lost loved ones due to Tasigna have sued Novartis. Here’s what you need to know.

What Is Tasigna?

Tasigna is a form of chemotherapy used to treat one specific genetically linked type of leukemia. In Ph+ CML, the bone marrow overproduces white blood cells. These extra white blood cells are abnormal and can overwhelm healthy cells, causing symptoms such as fatigue and anemia and eventually organ failure and premature death.

Tasigna is associated with a range of both “common” and “severe” side effects. On its website, Novartis warns that those side effects include, but aren’t limited to, the following:

nausea;
rash;
headache;
tiredness;
itching;
vomiting;
diarrhea;
cough;
constipation;
muscle and joint pain;
runny or stuffy nose, sneezing, and sore throat;
fever;
night sweats;
low blood count causing unexplained bleeding or weakness;
liver damage;
tumor lysis syndrome (TLS);
QT prolongation, a heart problem that causes an irregular heartbeat;
pancreas inflammation (pancreatitis);
bleeding in the brain, which may cause confusion or loss of consciousness;
fluid retention; and
decreased blood flow to the leg, heart, or brain.

As if that were not enough, there’s another problem with Tasigna that Novartis isn’t talking about.

Tasigna and Atherosclerosis

Scientific studies have shown that Tasigna is also associated with atherosclerosis, where fatty deposits build up in arteries. These deposits narrow the blood vessels, eventually slowing and even stopping the flow of blood throughout the body. Because blood distributes oxygen to cells, a reduction in blood flow can lead to cells literally suffocating. Depending on what area of the body is deprived of blood and oxygen, atherosclerosis can cause heart problems and stroke and can lead to amputation of limbs. (Note that atherosclerosis is a specific type of arteriosclerosis, or hardening of the arteries. These terms are often used interchangeably, so don’t be confused if you see discussions of Tasigna causing arteriosclerosis.)

As early as 2013, Canada issued a governmental warning about Tasigna, indicating that its use was associated with “the possible risk of developing atherosclerosis-related conditions.” Canada published its warning after finding that Novartis’s own global safety database revealed 277 cases of atherosclerosis between 2005 and 2013.

But Novartis has not included atherosclerosis as a risk in the information it distributes about Tasigna in the United States. Now, some patients and their families are taking Novartis to court over it.

Tasigna Lawsuits

Dainis Lauris was prescribed Tasigna for leukemia, but he soon developed peripheral artery disease. His doctor read that the drug was linked to atherosclerosis, causing problems just like Lauris’s, and quickly changed him to a different medication. But the damage was done: Lauris died from atherosclerosis complications about six months later. He was 49 years old. Now, his family has filed a lawsuit in California federal court. They allege that Novartis knew about the drug’s risks and intentionally failed to warn American consumers or their doctors. So far, the court has denied Novartis’s motion to dismiss the lawsuit and its motion for summary judgment. The case is awaiting trial.

I was involved in a case for the faulty hip replacements. Clay Hodges represented me. I can't say enough about how much he has helped me. Clay was able to win multiple settlements on my behalf with most of them being the maximum amount able to be awarded. Matt J.

Clay, thank you sir for making a disheartening experience at least palatable, you and your staff were honest, caring and understanding through the entire process of my wife’s hip replacements, while monetary settlements never make the pain and suffering end, it sometimes is the only way people can fight back to right a wrong. J. V.

We are absolutely pleased with how Clay Hodges handled my husband’s hip replacement claim. He always kept us informed of the progress. And, his work resulted in a settlement which we are extremely pleased. Thank you, Clay! Carol L. & Norm L.
