A division of the pharmaceutical company Bayer sold millions of dollars of blood-clotting medicine for hemophiliacs -- medicine that carried a high risk of transmitting AIDS -- to Asia and Latin America in the mid-1980's while selling a new, safer product in the West, according to documents obtained by The New York Times.
The Bayer unit, Cutter Biological, introduced its safer medicine in late February 1984 as evidence mounted that the earlier version was infecting hemophiliacs with H.I.V. Yet for over a year, the company continued to sell the old medicine overseas, prompting a United States regulator to accuse Cutter of breaking its promise to stop selling the product.
By continuing to sell the old version of the life-saving medicine, the records show, Cutter officials were trying to avoid being stuck with large stores of a product that was proving increasingly unmarketable in the United States and Europe.
Yet even after it began selling the new product, the company kept making the old medicine for several months more. A telex from Cutter to a distributor suggests one reason behind that decision, too: the company had several fixed-price contracts and believed that the old product would be cheaper to produce.
Nearly two decades later, the precise human toll of these marketing decisions is difficult, if not impossible, to document. Many patient records are now unavailable, and because an AIDS test was not developed until later in the epidemic, it is difficult to pinpoint when foreign hemophiliacs were infected with H.I.V. -- before Cutter began selling its safer medicine or afterward.
But in Hong Kong and Taiwan alone, more than 100 hemophiliacs got H.I.V. after using Cutter's old medicine, according to records and interviews. Many have since died. Cutter also continued to sell the older product after February 1984 in Malaysia, Singapore, Indonesia, Japan and Argentina, records show. The Cutter documents, which were produced in connection with lawsuits filed by American hemophiliacs, went largely unnoticed until The Times began asking about them.
''These are the most incriminating internal pharmaceutical industry documents I have ever seen,'' said Dr. Sidney M. Wolfe, who as director of the Public Citizen Health Research Group has been investigating the industry's practices for three decades.
Bayer officials, responding on behalf of Cutter and its president at the time, Jack Ryan, declined to be interviewed but did answer written questions. In a statement, Bayer said that Cutter had ''behaved responsibly, ethically and humanely'' in selling the old product overseas.
