Pfizer has reached a broad agreement to pay millions of dollars to Nigeria's Kano state to settle a criminal case alleging that the drug company illegally tested an experimental drug on gravely ill children during a 1996 meningitis epidemic. The details remain private, but sources close to the negotiations said the total payments -- including those to the children, their families, the government and the government's attorneys -- would be about $75 million under the current settlement terms. Other details, including how the money will be distributed, are to be worked out within weeks.
