What this Trial Is About

To define the best doses of sargramostim ( granulocyte-macrophage colony-stimulating factor; GM-CSF ), interferon alfa-2b ( IFN-A2b ), and zidovudine ( AZT ) to give together in patients with AIDS-associated Kaposi's sarcoma ( KS ), to learn about the side effects of these drugs when they are given together for 8 weeks, and to find out whether the combination of GM-CSF, IFN-A2b, and AZT has any effect on KS, HIV, or the immune system. Studies show that IFN-A2b can cause KS tumors to shrink or disappear in about 30 percent of patients. IFN-A2b can greatly reduce the growth of the HIV virus in test tube experiments and perhaps in patients. AZT has also been shown to reduce the growth of HIV and show improvements in the immune system with fewer infections. Test tube experiments show that when IFN-A2b and AZT are used together, they reduce the growth of the HIV virus much more effectively than when either drug is used alone. In recent studies of the combination of interferon alpha and AZT in patients with KS, more than 40 percent of the patients showed shrinkage of their tumors, and some showed evidence for suppression of HIV growth in the body. However, the combination of IFN-A2b with AZT often caused a marked lowering of the white blood cell (WBC) count, especially a type of WBC called the granulocyte (or neutrophil) which is important in the body's defense against infection. Recombinant human GM-CSF is a human protein which is produced in bacteria. It has been shown to cause an increase in the WBC count.
