Brief Summary

This study will compare 2 treatments in the way they affect cholesterol levels and the amount of HIV in the blood.

Detailed Description

The study is designed to determine the metabolic changes, antiviral activity, safety, and tolerability of atazanavir as compared to LPV/RTV, each in combination with 2 nucleosides, over the initial 24 weeks, with a final analysis at 48 weeks.
