History of Changes


The purpose of this study is to determine if two dose levels of indinavir combined with two nucleoside analogue reverse transcriptase inhibitors (NRTIs) have the same effect on plasma viral load (level of HIV in the blood).

Condition Intervention Phase
HIV Infections

Drug : Indinavir sulfate
Phase 3

Study Type: Interventional
Study Design: Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: A Multicenter, Open-Label, Randomized, 24-Week Study to Compare the Safety and Activity of Indinavir Sulphate, 800 Mg q 8h Versus 1,200 Mg q 12h in HIV-Infected Individuals Having Plasma Viral RNA Less Than 400 Copies/Ml, on Concomitant Therapy With 2 Nucleoside Analogue Reverse Transcriptase Inhibitors (NRTI)

Further study details as provided by NIH AIDS Clinical Trials Information Service:

Enrollment: 350

Detailed Description:

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.



Ages Eligible for Study: 16 Years and older  
Sexes Eligible for Study: All  
Accepts Healthy Volunteers: No  


Inclusion Criteria
Patients must have:

  • Documented HIV-1 seropositive status.
