Estudio de una vez al día de abacavir / lamivudina Versus tenofovir / emtricitabina, se administra con efavirenz en tratamiento antirretroviral previo, VIH-1 sujetos adultos infectados

Recently, the fixed-dose combinations (FDC) KIVEXA™ (abacavir/lamivudine) and TRUVADA (tenofovir disoproxil fumarate/emtricitabine) have facilitated the usage of once-daily regimens. However data from head-to-head randomized trials comparing these two FDCs as part of an initial regimen are not available at present. The long-term toxicity profiles of these regimens are of particular importance, as treatment of HIV is currently life-long and therefore, minimizing long-term toxicity and maximizing adherence and duration of regimen maintenance are critical therapy objectives.

The primary endpoint is estimated glomerular filtration rate (GFR), as measured by the modified diet in renal disease (MDRD) equation, a validated estimate of renal function.
