| Objectives | |
| Narrative objectives1 | A non-inferiority randomized control trial in treatment naive HIV patients to compare virologic effect of two backbone regimens with Epzicom (lamivudine and abacavir) and Truvada (emtricitabine and tenofovir). Both arms are treated with fixed combination of retonavir boosted atazanavir as key drugs. |
