AZT is an antiviral drug, which has been shown to be beneficial in some patients with AIDS. IL-2 is a substance found naturally in the body that boosts the body's immune response to invading organisms and tumor cells. These two drugs, when administered together, may have a mutually helpful effect in treating AIDS patients, but before this effect can be studied, it is important to understand the proper dose and any side effects that may occur when these drugs are used together. The study will show how much AZT and IL-2 patients can safely take at the same time and how the two drugs will interact with each other.
