A Multicenter, Prospective, Randomized, Double-Blind, Placebo-Controlled Trial of Three Preparations of Low-Dose Oral Alpha Interferon in HIV-Infected Patients With CD4+ Counts >= 50 and <= 350 Cells/mm3

Previous or ongoing clinical trials to test the efficacy of low-dose oral interferon alpha have produced different results, and it is not clear whether the differences were due to the interferon alpha products used or to problems in the study design. Therefore, three preparations will be compared to evaluate their potential efficacies. Patients are randomized to receive 6 months of Alferon LDO alone, Alferon with Veldona, Alferon with Ferimmune, or three placebos, with follow-up visits monthly.
