Side Effects of Byetta and Pancreatic Cancer
Reports connecting Byetta to pancreatic cancer began surfacing shortly after its introduction to the consumer marketplace in April of 2005. Patients have had issues ranging from pancreatic inflammation to the diagnosis of pancreatic cancer.
Chronic Pancreatitis and Cancer from Byetta
Only a few years after its introduction, Byetta was linked to increasing reports about patients who had developed pancreatitis, or inflammation of the pancreas. Amylin Pharmaceuticals, makers of Byetta, has stood by its medication and says there is no connection to pancreatic ailments, despite the several reports that have come to light. Patients with chronic pancreatitis have a substantially increased risk of developing cancer of the pancreas, a risk which Amylin (now Bristol Meyers-Squibb) had failed to warn consumers about.
Pancreatic cancer is the fourth most common cause of cancer-related deaths in the United States. Because of the failure to warn patients of the associated risks, people may face the development of cancer if early detection of pancreatitis is not discovered. The risk for cancer may increase the longer the patient undergoes treatment with Byetta.
Byetta and Thyroid Cancer
In addition to a potential link between Byetta and pancreatic issues, studies have indicated that use of Byetta significantly increased the risk of people developing Byetta thyroid cancer, by a ratio of 4.7. The Thyroid is a gland in the front of the neck responsible for producing metabolic hormones, and can cause symptoms such as enlargement of the neck, persistent cough, trouble swallowing, or pain in the neck or ears, among others.
Studies Show Byetta Cancer Link
Numerous studies and reports have shown a link between Byetta and pancreatic cancer:
- In both October 2007 and August 2008, the FDA issued warnings about reports of pancreatitis problems from Byetta, submitted by Doctors and patients.
- In February 2010, the medical journal Diabetes Care published an article highlighting further concerns about the link between pancreatitis and Byetta.
- In February 2011, the medical journal Gastroenterology, published another article that provided further evidence of the potential link between Byetta and pancreatic cancer, while also highlighting concerns about a possible risk of thyroid cancer.
- In May 2011, the Drug Commission of the German Medical Association also released date showing the high risk of pancreatic cancer for Byetta users.
- A new study recently published in February 2013 in the medical journal JAMA Internal Medicine released a study of 2,538 adults with type 2 diabetes, half of which were hospitalized for pancreatic inflammation.
