The Justice Department said the drugmaker Wyeth, which Pfizer bought in October 2009, trained sales representatives to encourage doctors to prescribe Rapamune for uses other than preventing rejection of transplanted kidneys, even giving them bonuses for doing so.
Rapamune was approved in 1999, only for use in kidney transplant patients. Federal laws bar drugmakers from promoting drugs for uses not specifically approved by the Food and Drug Administration.
But the practice has previously been so rampant that there's a term for it—off-label marketing—and multiple law firms specialize in pursuing lawsuits over it. Nearly every big drugmaker, including Pfizer, has been prosecuted for it and eventually agreed to big settlements with the government and whistle-blowers, who usually are drug store pharmacists or former pharmaceutical sales reps. The record settlement is $3 billion, paid by British drugmaker GlaxoSmithKline.
In the Rapamune case, whistle-blower Mark Campbell, a Wyeth sales rep for 20 years until he resigned in 2009, alleged Wyeth promoted Rapamune for patients getting liver, lung, heart and other transplants—potentially dangerous uses.
"I believe this settlement represents at least a small step towards insuring that pharmaceuticals are promoted in a manner which does not compromise patient safety," Campbell said in a statement.
Pfizer said In a statement that it "was not a subject or target of this matter, and cooperated fully with the government from the time it learned of this investigation in October 2009. That cooperation was acknowledged today by the Justice Department."
Campbell's lead attorney, Shelley Slade of Vogel, Slade & Goldstein, said the federal and state governments splitting the settlement from Wyeth are still working out how much of that money will go to the three whistle-blowers, who worked together on the case. The other two, Marlene Sandler and Scott Paris, were represented by another law firm.
Pfizer shares fell 13 cents to $29.67 in trading Tuesday.
