Yamada's Response to Dr John Buse's Safety Concerns about GSK's Avandia

After Dr. John Buse raised concerns in 1999 about possible cardiovascular risks associated with GSK's diabetes drug Avandia, the company was quick to respond. In November 2007 a United States Senate Committee on Finance staff report revealed that Yamada had played a role in GSK's campaign to neutralise Buse's criticisms. Drawing on internal company documents, the committee's staff report stated that as the head of GSK's research department, Yamada had "discussed Dr. Buse with GSK's CEO Dr. Jean-Pierre Garnier as well as David Stout, a senior GSK executive. Dr. Garnier and Mr. Stout are copied on the email." [3]

In his email, Yamada wrote:

In any case, I plan to speak to Fred Sparling, his former chairman as soon as possible. I think there are two courses of action. One is to sue him for knowingly defaming our product even after we have set him straight as to the facts—the other is to launch a well planned offensive on behalf of Avandia ..."[3]

The report noted that "indeed, Dr. Yamada called Fred Sparling, Dr. Buse's department chairman. Three days later, Dr. Buse wrote a letter to Dr. Yamada attempting to clarify his position on Avandia. Dr. Buse's letter began, 'I wanted to set the record straight regarding all the phone calls and questions I have received….' The phone calls that Dr. Buse referred to were made by GSK officials including Dr. Yamada regarding the speeches that Dr. Buse gave at conferences suggesting cardiovascular problems associated with Avandia."[3]
