From gwyn@annwfn.indstate.edu Wed Nov 23 14:17:26 1994 The following story is a follow-up to yesterday's announcement about the results of the European study of the use of 3TC and AZT in combination against AIDS. It is from _The Globe and Mail_, Tuesday, November 22, 1994.

The new compound -- known as 3TC -- reportedly reduced replication of the human immunodeficiency virus in the blood when used in combination with the drug AZT. The announcement brought a barrage of phone calls to doctor's offices from patients who believed a cure, or something close to it, had been found. But a Canadian AIDS researcher was quick to call the reports misleading because the findings give no indication of whether the drug will help AIDS patients in the long term. "There just isn't enough data to comment upon whether or not it extends life," said Dr. Douglas MacFadden, an assistant professor at the University of Toronto who reviewed the results yesterday. The preliminary results, based on research done in Europe, were released Sunday at an international conference in Glasgow by representatives of BioChem Pharma Ltd., the Montreal-based company that developed 3TC. John Russell, a spokesman for the AIDS Committee of Toronto, said that while the results seem encouraging, "we've seen this a lot over the past 10 years. Something looks very good in early trials but then for one reason or another it doesn't pan out." Claudio Brabazon, a spokeswoman for the Canadian AIDS Society in Ottawa, said the latest study is just another step in the process of finding an AIDS cure. She characterized the reports as "not terribly exciting." BioChem officials could not be reached for comment yesterday. Dr. Philip Berger, who treats HIV-infected patients in Toronto, was more blunt. "There is no indication that this combination [3TC and AZT] will be any different clinically than anything else we have." Existing treatment are of extremely limited value in controlling the disease, he said. The two drugs in combination were found to combat the virus during an early stage of replication within a type of immune cell known as T-4, before the virus takes over the cell by hijacking its DNA. However, other research has shown that by the time most people know they are infected with HIV, the virus has already spread extensively through the body's T-4 cells. A recent international AIDS conference in Japan was told that soon after a patient is infected with HIV, the virus integrates itself into as many as 25 per cent of the T-4 cells. Dr. Berger said the extent of infection is "so great that none of the current therapies can keep up with the destruction that will result from those 25 per cent of infected cells." Dr. Berger, who is chief of the department of family and community medicine at Wellesely Hospital in Toronto, was highly critical of the way the experimental data were handled by BioChem Pharma and the news media. "All of us [physicians treating AIDS] were rolling our eyes this morning in anticipation of all the phone calls from desperate people who are looking for a final hope," he said. His expectations were soon borne out. "The word on the street is that a near-cure has been found for AIDS," he said. Patients and their physicians need to be informed about developments in AIDS research, but "it is irresponsible for drug companies ... to promote their drug in this high-profile fashion which gives people a hope which doesn't exist in reality," Dr. Berger said. "And it's equally irresponsible for the media to co-operate in that type of promotion ... It's reckless and it causes a great deal of pain." Despite the efforts by researchers and AIDS activists to put the latest findings into proper perspective, Dr. MacFadden expects physicians to be inundated with more inquiries from desperate patients. * * * * *
