OUTLINE: This is a randomized, open-label, multicenter study. Patients are stratified according to CD4 count (less than 100/mm^3 vs at least 100/mm^3), age-adjusted International Prognostic Index adverse risk factors (0 or 1 vs 2 or 3), and concurrent antiretroviral therapy (yes vs no). Patients are randomized to 1 of 2 treatment arms.
