Pharma giant Pfizer used dirty tricks to escape law: WikiLeaks

London: Drugmaker Pfizer hired investigators to find evidence of corruption against the Nigerian attorney general to convince him to drop legal action against the company over a drug trial involving children, the Guardian newspaper reported, citing US diplomatic cables made public by WikiLeaks.

Nigeria's Kano state sued the world's largest drugmaker in May 2007 for USD 2 billion in damages over testing of the meningitis drug Trovan, which state authorities said killed 11 children and left dozens disabled.

Pfizer and Kano's state government signed a USD 75 million settlement on July 30.

However it was yet to be verified that the content of the leaked cables, and Pfizer officials were not immediately available for comment.
The Guardian reported on its website on Thursday that a memo leaked by WikiLeaks referenced a meeting between Pfizer's country manager Enrico Liggeri and US officials suggesting that the drug company did not want to pay to settle two cases brought by Nigeria's federal government.

"According to Liggeri, Pfizer had hired investigators to uncover corruption links to federal attorney general Michael Aondoakaa to expose him and put pressure on him to drop the federal cases," according to an April 2009 cable from Economic Counselor Robert Tansey of the US embassy in Abuja, cited in the Guardian report.

"He said Pfizer's investigators were passing this information to local media."

Aondoakaa was removed from the position of justice minister in February this year by Nigerian President Goodluck Jonathan.

"A series of damaging articles detailing Aondoakaa's 'alleged' corruption ties were published in February and March," the cable said.

"Liggeri contended that Pfizer had much more damaging information on Aondoakaa and that Aondoakaa's cronies were pressuring him to drop the suit for fear of further negative articles," it said.

In 1998, the US Food and Drug Administration approved Trovan for use by adults only. After reports of liver failure, its use in the United States was restricted to adult emergency care. The European Union banned its use in 1999.
