Researchers Are Optimistic About New Drug for AIDS AL721




 

BOSTON, Nov. 14--Researchers at the National Cancer Institute say they are optimistic that a new drug called AL721 will fight the acquired immune deficiency syndrome (AIDS) virus without many of the serious side effects of other drugs.

"AL721 is a promising new candidate for clinical investigation in the treatment of AIDS and AIDS-related complex," scientists said in a letter to the editor of the New England Journal of Medicine.

"But it should be emphasized that results so far are very preliminary and that much more work will be required to determine the clinical usefulness of this agent," said the letter, signed by Drs. Robert Gallo and Prem S. Sarin from the NCI and researchers from Yale University, the University of Florida and Matrix Research Laboratories, makers of the drug.

The drug attacks the AIDS virus by breaking down its outer shell. With its shell not intact, the virus cannot infect cells. AL721, when mixed in a test tube with human cells and HTLV-III, the virus that causes AIDS, slows its spread among cells. Preliminary trials found the drug restored immune system function in elderly people without adverse side effects.

"AL721 is a drug with a novel mechanism of action compared to other AIDS drugs currently being studied," Sarin said in a statement released by the NCI. "The drug appears to be nontoxic for normal cel ls grown in the lab.
