Naïve HIV POC Monotherapy Trial

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
