AMENDED: To investigate whether subcutaneous (SC) injection of IL-2 produces biological responses which parallel those observed with IV dosing. Original design: To evaluate the short-term effects of combined administration of zidovudine (AZT) and increasing doses of recombinant interleukin-2 (aldesleukin; IL-2) in patients infected with HIV, who have lymphadenopathy, but who are otherwise asymptomatic (no other symptoms). The first phase of this clinical trial will establish maximum tolerated dose ( MTD ). How quickly the drugs get into the blood and how long they remain there (pharmacokinetics) will also be studied at each dose as well as the effect on HIV.
