Avandia was approved by the FDA for the treatment of Type 2 diabetes in 1999, and grew to become a $3 billion a year industry for GSK. In 2007, a study was published in the New England Journal of Medicine that linked Advandia to a 43 percent increased risk of heart disease. The senators contend that the London-based GSK got its hands on a copy of the report before it was published and the drug company quickly initiated a public relations push to counter any questions about Avandia’s link to increased heart risk. The drug company also urged the medical researchers who identified the risk of heart and liver problems in patients taking Avandia to stop publishing their findings.

The effort kept the drug on the market, but GSK took a near-$2 billion hit in sales in 2009. A company spokeswoman said in a statement, “the scientific evidence simply does not establish that Avandia increases ischemic cardiovascular risk or causes myocardial ischemic events … Based on the scientific evidence and a recommendation by an independent advisory committee of experts convened by the FDA, the agency has ruled that Avandia remain available to patients for the treatment of Type 2 diabetes.”

Senators Baucus and Crassley disagree. “It can be argued that GSK had a duty to warn patients and the FDA of the Company’s concerns,” wrote Baucus and Grassley in the Senate committee report. “Instead, GlaxoSmithKline executives attempted to intimidate independent physicians, focused on strategies to minimize or misrepresent findings that Avandia may increase cardiovascular risk, and sought ways to downplay findings that a competing drug might reduce cardiovascular risk.”
