Patients are randomized to receive IFN-A or IFN-A2A by intramuscular injection and combined with AZT orally daily for 8 weeks. Two cohorts of 4 patients enter each dose level. Patients do not enter into the next dose level until all patients have completed 3 weeks of treatment. AZT escalates only if there is no unacceptable toxicity (grade 2 in = or > 3 patients or > grade 2 in any patients); subsequent increase in IFN-A or IFN-A2A will be permitted, but the AZT dose will remain fixed. The MTD for a given IFN-A or IFN-A2A dose level is defined as grade 3 toxicity for hemoglobin or grade 2 toxicity for other parameters in 3 of the 6 patients. Once the MTD is reached, there will be no further enrollment at higher dose level. Patients are followed every week for vital signs and hematologic studies. Patients tolerating the combination may be continued on therapy for 1 year at the same dose as the end of 8th week.
