F O L L O W - U P MORE 3TC AVAILABLE by Rex Wockner The Glaxo Wellcome pharmaceutical company has relaxed access requirements for its promising anti-HIV drug 3TC, which is awaiting Food and Drug Administration approval. Due to alleged shortages of the drug, the company was providing 3TC only to people with fewer than 100 CD4 cells and limiting new enrollees to 350 per week, which had created a waiting list of more than two months. Now there are 650 slots per week and CD4 cells can be as high as 300. The drug is free until the FDA approves it for the market. To get 3TC, one's doctor should phone (800) 248-9757. 3TC has been shown in trial studies to substantially increase CD4 immune-system cells, to reduce HIV levels in blood cells by 99 percent, and to reduce levels of HIV in the bloodstream by 91 percent. These results, which have been shown to persist for at least one year (there have been no longer studies), occur only when 3TC is used in combination with AZT. It is theorized that when HIV mutates around AZT in an individual, it is then susceptible to 3TC, and that when it then mutates around 3TC, it mutates in a specific direction that once again makes it susceptible to AZT. The respected Bulletin of Experimental Treatments for AIDS (BETA) says of the 3TC/AZT combination: "[It] produces the most pronounced and prolonged effect of any anti-HIV regimen yet studied in suppressing HIV replication and increasing CD4 counts. [It is] a remarkable combination." Glaxo Wellcome had blamed the earlier severe shortages on inadequate production facilities. The company said it was remodeling a factory in England to produce vastly larger quantities of the drug. Meanwhile, newer trial studies are hinting that 3TC and AZT taken together with a "protease inhibitor" can produce even more dramatic results. The protease inhibitors, of which there are several in trial studies, are an entirely new class of anti-HIV therapy. All previous therapies (AZT, DDI, DDC, D4T and 3TC) belong to the "nucleoside analogue" class of drugs. == end ==
