The primary objective of the trial is:
• to evaluate the change from baseline in plasma viral load with placebo and one of up to 4 dose regimens of RDEA806.
The secondary objectives are:
Efficacy
- to describe the nadir of the plasma viral load
- to describe the DAVG
- to assess the proportion of subjects who reached a drop in viral load of 0.5 log, 1 log, or reach an undetectable viral load
- to assess the plasma viral load decay rate
- to evaluate immunologic changes (as measured by CD4 and CD8 cells)
- to evaluate the genotypic and phenotypic pattern of the virus Pharmacokinetics
- to evaluate the pharmacokinetics and the pharmacokinetic/pharmacodynamic relationship of RDEA806 Safety
- to evaluate the safety and tolerability of bid and qd dosing of RDEA806 as monotherapy

- Change from baseline in HIV plasma viral load [ Time Frame: 9 days ]
- Safety will be assessed as adverse and HIV related events, clinical laboratory test results(hematology, chemistry, urinalysis), vital signs, 12-lead electrocardiograms (ECGs), and physical examination [ Time Frame: 22 days ]
- Pharmacokinetics and Resistance [ Time Frame: 22 days ]
