Tenofovir DF + Efavirenz (TDF+EFV) Versus Tenofovir DF + Efavirenz + Lamivudine (TDF+EFV+3TC) Maintenance Regimen in Virologically Controlled Patients: COOL Trial (COOL)

June 27, 2008 updated by: Gilead Sciences

Randomized Multicenter Open-Label, Pilot Trial to Evaluate the Efficacy and Safety of Switching HIV-1 Stable Infected Patients Under HAART to a New Once Daily Triple Therapy Combination Including EFV+3TC+TDF Versus a Dual QD Therapy Containing EFV+TDF

Primary objective: Evaluation of the efficacy of TDF+3TC+EFV versus TDF+EFV QD to maintain plasma HIV-1 RNA BLQ (< 50 copies/mL) (c/mL) at 48 weeks (W48)

Main Secondary objectives:

Comparison of the two arms for genotypic resistance profile in case of virological failure

CD4 changes from baseline

Evolution of the lipid profile and morphological changes in fat distribution, and safety

Efficacy and genotypic profile data, results of lipid markers, morphological changes and main biological parameters
