by a revised black box warning in November, 2007. You may read a copy of the black box warning at < http://www.fda.gov/cder/foi/la bel/2007/021071s028lbl.pdf>. At that time, the FDA concluded there wasn't enough evidence that Avandia had greater risks than any other similar diabetes drug. They requested a new study be undertaken by GlaxoSmithKline.

In June, 2007, a Congressional investigation began. A hearing was called by Rep. Henry Waxman of the House Committee on Oversight and Government Reform to discuss the FDA's safety assessment of Avandia. Dr. John Buse and Dr. Stephen Nissen were called as witnesses. Dr. Buse acknowledged that he had felt intimidated by Glaxo when he raised concerns about the risks of Avandia. The head of the FDA at the time, Dr. Andrew Von Eschenbach testified that Glaxo provided reports from studies about Avandia in 2006. Since the results from the studies were inconsistent, the FDA began their own investigation to determine risks associated with the drug.

The latest Avandia label revision was in October, 2008. Today, it carries a strong warning of serious side effects including new or worse heart failures, an increase in the risk of heart problems associated with a reduced blood flow to the heart, and other serious side effects.

Recent Court Actions:

With multiple lawsuits filed all over the United States, a motion was made to The United States Judicial Panel on Multidistrict Litigation (the MDL Panel) to determine if there was merit in transfering them to one federal district. The suit titled, Avandia Marketing, Sales, Practices and Products Liability, was assigned a docket number, MDL No., 1871. The case was filed in the U.S. District Court for the Eastern District of Pennsylvania, where GlaxoSmithKline is headquartered, in October, 2007, under Judge Cynthia M. Rufe. The Case Management Order, Tolling Agreement, and Plaintiff Fact Sheet Documents are available to the public online at: < http://www.paed.uscourts.gov/m dl1871.asp>.
