A "whistleblower suit" was filed against Wyeth in 2005 alleging that the company illegally marketed their drug Rapamune . Wyeth is targeted in the suit for off-label marketing , targeting specific doctors and medical facilities to increased sales of Rapamune, trying to get current transplant patients to change from their current transplant drugs to Rapamune and for specifically targeting African-Americans. According to the whistleblowers, Wyeth also provided doctors and hospitals with kickbacks to prescribe the drug in the form of grants, donations and other money.   A US House of Representatives committee, led by Rep. Edolphus Towns is investigating Wyeth for these abuses.
