GlaxoSmithKline, the maker of diabetes drug Avandia, knew its drug posed serious heart attack and heart failure risks, but hid that information from the public for years, according to a Senate report released Saturday, confirming legal claims made in lawsuits across the nation.
The report, which concluded two years of investigation, is harshly critical of FDA procedures that have kept Avandia (rosiglitazone) on the market, in spite of internal protests by doctors within the agency. Senators Max Baucus and Chuck Grassley led the effort to produce the report, released Saturday by the Senate Finance Committee.
Every month, 500 people suffer heart attacks and another 300 suffer heart failure because they are taking Avandia instead of a safer diabetes drug known as Actos (pioglitazone), according to the Senate report. Actos, marketed by Pfizer, provides at least as much diabetes protection without causing the heart attacks and heart failures linked to Avandia, according to the Senate report.
In light of the Avandia dangers, known for years within GSK and within the FDA, some doctors in the agency have been demanding that the FDA pull Avandia from the market. An FDA safety committee came within one vote of recommending such action in 2007, after studies showed Avandia had caused 83,000 deaths between 1999 and 2007, according to the Grassley/Baucus report.
The senators are demanding that FDA Commissioner Margaret Hamburg provide some answers by March 4. Specifically, the senators want to know why the FDA has allowed GlaxoSmithKline (GSK) to proceed with a years-long study that is designed to defend Avandia when the study itself will put participants at risk of heart attacks.
The FDA told GSK to go ahead with a study that is supposed to compare Avandia with the competing drug Actos, marketed by Pfizer. However, several previous scientific studies had already established that Avandia poses greater health risks without any added benefits over Actos. The design of the study would require giving a drug known to increase risk of heart failure to some participants when doctors already know Actos provides the same benefits without the same level of risk.
The bipartisan Senate report says GSK should have warned patients years ago that Avandia was potentially deadly. The two-year investigation concluded that:
“GSK was aware of the possible cardiac risks associated with Avandia years before such evidence became public.… Based on this knowledge, GSK had a duty to sufficiently warn patients and the FDA of its concerns in a timely manner. Instead, GSK executives intimidated independent physicians, focused on strategies to minimize findings that Avandia may increase cardiovascular risk, and sought ways to downplay findings that the rival drug ACTOS (pioglitazone) might reduce cardiovascular risk.” (Baucus/Grassley letter to FDA)
Numerous Avandia users have filed lawsuits against GSK over the past several years, as more patients suffer heart attacks, heart failure, and other problems after using Avandia. The law firm of Aylstock, Witkin, Kreis & Overholtz (AWKO Law) has been actively engaged in the litigation for years, including a leadership role in the national Avandia multi-district litigation (MDL), which consolidates thousands of lawsuits to streamline the information discovery process.
