Thousands of hemophiliacs filed a class-action lawsuit Monday against Bayer Corp. and several other companies, claiming they knowingly sold blood contaminated with HIV and hepatitis C.
The lawsuit, filed in federal court, alleges the companies conspired to sell blood-clotting products that were manufactured using blood from sick, high-risk donors. It also alleges the companies continued distributing them abroad in 1984 and 1985, after they stopped selling them in the United States because of the known risk of HIV and hepatitis transmission.
Bayer A.G., the giant West German chemical company, said today that it had been sued over its sale of hemophilia drugs that may have been infected with the AIDS virus.
A Bayer statement said fewer than 20 patients who have been treated with the Factor VIII hemophilia drug have filed liability claims against the company charging that the substance was contaminated with the AIDS virus.
