In this open-label study 350 seropositive HIV-1 men and women are first stratified according to baseline plasma viral RNA (less than 400 copies/mL vs negative plasma viral RNA result) then randomized into one of two arms:
Arm 1: Indinavir (800 mg, q8h) plus two pre-existing NRTIs. Arm 2: Indinavir (1,200 mg, q12h) plus two pre-existing NRTIs. Plasma viral RNA will be measured every 4 weeks for the duration of the 24-week study.
