The Safety and Effectiveness of a Type of Interleukin-2 Plus Zidovudine Plus Thymosin in HIV-Positive Patients With and Without Symptoms of Infection

To determine the safety of thymosin alpha 1 given twice weekly in a regimen of daily oral zidovudine (AZT) and biweekly polyethylene glycolated interleukin-2 (PEG IL-2). To determine the effect of thymosin alpha 1 and PEG IL-2 in combination with AZT on immunologic and pharmacokinetic markers.

AIDS is characterized by diminished T helper cell number and function. Thymosin alpha 1 appears to both increase IL-2 receptors on lymphocytes in vitro and enhance lymphocyte maturation in vivo; thus, the drug may further enhance the CD4 T cell levels in patients receiving AZT and PEG IL-2.
