Januvia (sitagliptin) is a once-daily oral diabetes medication. When used in combination with diet and exercise, Januvia can help a diabetic person control their blood-sugar levels. Januvia was developed by Merck & Co., and the U.S. Food and Drug Administration (FDA) approved it in 2006.

Januvia belongs to a new class of diabetes drugs that works by inhibiting an enzyme called dipeptidyl peptidase-4 (DPP-4). Normally, DPP-4 breaks down hormones (such as GLP-1) which tells the body to produce insulin. By inhibiting DPP-4, the hormone GLP-1 lasts longer in the body, and stimulates the body to produce extra amounts of insulin.

Insulin triggers cells to absorb blood-sugar, which lowers total blood-sugar levels. People with Type-2 diabetes have chronic problems controlling their blood-sugar, because their cells do not respond to normal amounts of insulin. Drugs like Januvia help control blood-sugar by helping the body produce more insulin.

Januvia and Cancer

In 2011, Gastroenterology published a study that found an increased risk of cancer. Researchers from the University of California, Los Angeles (UCLA) looked at the FDA’s public database of adverse event reports from 2004-2009. Physicians voluntarily submit these reports after they treat patients for serious drug side effects.

The researchers collected reports for Januvia, Byetta, and other diabetes drugs, and compared the rates of pancreatic cancer. The researchers found that patients who were taking Januvia were 2.7-times more likely to have pancreatic cancer.

Within two months after this study was published, two major drug companies sent letters to Gastroenterology requesting that the study be withdrawn. The drug companies called the researchers’ findings “unjustified” and warned that people taking Januvia might be unnecessarily scared about the health risks. Gastroenterology officially withdrew the article.

Januvia Pancreatic Cancer

Pancreatic cancer is one of the deadliest types of cancers. It is fast-growing and rarely produces serious symptoms in its early stages, which delays diagnosis. By the time diagnosis occurs, more than 80% of people cannot be cured by surgical removal of cancerous pancreatic tissue. The average survival time is one year, with fewer than 5% of people surviving for five years.
