Note: This press release was updated on June 7 to reflect an updated number of people who have received Avandia in the U.S. since the EMA banned it and inj 2012 specifically.

Avandia: A Drug That Should Be Banned

Statement of Sidney M. Wolfe MD, Founder and Senior Adviser, Public Citizen’s Health Research Group

Note: Dr. Sidney Wolfe is testifying today before two FDA advisory committees that are meeting to consider a range of actions on the dangerous diabetes drug Avandia (rosiglitazone), from lifting restrictions to banning it. Dr. Wolfe’s testimony is available here. In 2008, Public Citizen petitioned to have Avandia banned.

According to U.S. Food and Drug Administration-acquired marketing data, since late 2010, when the diabetes drug Avandia was removed from the market in Europe because of its cardiovascular risks, approximately 132,000 Americans have been prescribed this dangerous drug, likely resulting in hundreds, or more, serious – and sometimes fatal – adverse reactions, including heart failure and heart attacks.

In September 2010, the FDA and the European Medicines Agency (EMA) reached very different conclusions about the fate of this once top-selling diabetes drug, although both authorities had access to the same safety studies. The EMA concluded that new data support an increased cardiovascular risk associated with Avandia, also known as rosiglitazone. Since they “could not identify additional measures that would reduce the cardiovascular risk,” they “therefore concluded that the benefits of rosiglitazone no longer outweigh its risks and recommended the suspension of the marketing authorisation of the medicine.”

The FDA, in contrast, decided in September 2010, after a July 2010 advisory committee meeting, not to ban the drug but instead to institute a risk evaluation and management strategy (REMS) to limit the use of the drug to those they believed could benefit from it. One excuse for not acting more forcefully was that the FDA wanted Avandia’s manufacturer, GlaxoSmithKline, to fund a study to re-evaluate a previous study (called RECORD) on heart risk. The company had been asked by the EMA to do the study shortly after Avandia’s approval by the FDA in 1999. That re-evaluation (re-adjudication) of RECORD is the main topic of today’s FDA advisory committee meeting.

The EMA was so appropriately concerned about Avandia’s dangers that it banned the drug, stating that the only way it could ever be marketed again in Europe was if Glaxo could “provide convincing data to identify a group of patients in whom the benefits of the medicines outweigh their risks.” It did not waste time with any further evaluation of the RECORD study it had required Glaxo to do.

The reckless FDA conclusion was to eventually institute a REMS (not approved until May 2011 and fully in place until six months later), although there has never been any evidence that those getting the drug were patients for whom its benefits outweighed the risks.

Once again, instead of banning a drug, as recommended by 12 FDA advisory committee members, and as the EMA has done (because the drug has no unique benefits but unique risks), the FDA hides behind a REMS program that has reduced the number of people using the drug in the U.S. to 2,400 in 2012. Unfortunately, in the interval since the EMA ban, more than 135,000 people used Avandia in the U.S., likely resulting in hundreds of preventable injuries and deaths. REMS should be reserved for drugs that need to remain available. By no stretch of the imagination is Avandia such a drug. Ask the EMA.

Public Citizen, Inc. and Public Citizen Foundation

 

Together, two separate corporate entities called Public Citizen, Inc. and Public Citizen Foundation, Inc., form Public Citizen. Both entities are part of the same overall organization, and this Web site refers to the two organizations collectively as Public Citizen.

Although the work of the two components overlaps, some activities are done by one component and not the other. The primary distinction is with respect to lobbying activity. Public Citizen, Inc., an IRS § 501(c)(4) entity, lobbies Congress to advance Public Citizen’s mission of protecting public health and safety, advancing government transparency, and urging corporate accountability. Public Citizen Foundation, however, is an IRS § 501(c)(3) organization. Accordingly, its ability to engage in lobbying is limited by federal law, but it may receive donations that are tax-deductible by the contributor. Public Citizen Inc. does most of the lobbying activity discussed on the Public Citizen Web site. Public Citizen Foundation performs most of the litigation and education activities discussed on the Web site.

You may make a contribution to Public Citizen, Inc., Public Citizen Foundation, or both. Contributions to both organizations are used to support our public interest work. However, each Public Citizen component will use only the funds contributed directly to it to carry out the activities it conducts as part of Public Citizen’s mission. Only gifts to the Foundation are tax-deductible. Individuals who want to join Public Citizen should make a contribution to Public Citizen, Inc., which will not be tax deductible.
