Metabolic Effects of Atazanavir/Ritonavir Versus Darunavir/Ritonavir in Combination With Tenofovir/Emtricitabine in naïve HIV-1 Infected Patients

Registration Number
NCT01274780
Lead Sponsor
Juan A. Arnaiz
Brief Summary

This is a prospective, open controlled trial in which naïve HIV-1 patients will be randomized to receive atazanavir / ritonavir or darunavir / ritonavir in combination with tenofovir / emtricitabine. They will be followed up during 96 weeks to determinate the cholesterol levels.

Randomization will be stratified according to the values of the ratio of total cholesterol/HDL cholesterol obtained during the screening visit (as they will be \<4.5 or ≥ 4.5).
