| Measure | Time frame |
|---|---|
| Main Objective: The main objective of this study was to determine the feasibility of maintaining virologic suppression on standard plasma viral load (limit of detection 37 copies / mL) of a dose reduction strategy of ATRIPLA ® once a day to three tablets per weeks in patients infected with HIV-1 with sustained suppression of plasma viral load standard for more than two years.;Secondary Objective: ? virological study including: ultrasensitive viral load in plasma (limit of detection 1 copy / mL), and HIV-1 reservoir mononucelares cells from peripheral blood, ? immune Study includes TRECs production, immune profile of activation (CD38 and HLA-DR) and senescence (CD57 and CD28) in the CD4 and CD8 lineage, apoptosis (annexin V staining), and naive T-cell ratios and effector and memory (CCR7 and CD45RA). ? Pharmacokinetic study, including basal plasma levels of efavirenz at the beginning and end of study. ? Safety study, including: test on sleep quality (Pittsburgh Sleep Quality Index), levels of vitamin-D 25OH, estimated glomerular filtration rate (CPK-EPI) and lipids (triglycerides, total cholesterol and HDL) plasma at the beginning and at end of study and overall tolerability.;Primary end point(s): The primary endpoint will be the proportion of patients who continue with a standard plasma viral load (<37 copies / mL) at 24 weeks by intention to treat analysis.;Timepoint(s) of evaluation of this end point: 24 weeks | — |
Secondary
| Measure | Time frame |
|---|---|
| Secondary end point(s): 1) The proportion of patients with ultrasensitive viral load (<1 copy / mL) after 24 weeks. 2) The change from baseline to 24 weeks in the viral reservoir in peripheral blood mononuclear cells 3) Changes from baseline to 24 weeks in the production of TRECs, the immunological profile of activation (CD38 and HLA-DR) and senescence (CD57 and CD28) in CD4 and CD8 lineages in the proportions of naive T cells effector and memory (CCR7 and CD45RA), and changes in the levels of apoptosis in vitro by staining with annexin V. 4) Changes in plasma levels of efavirenz. 5) Changes in sleep quality (Pittsburgh Sleep Quality Index), plasma levels of vitamin D and lipids, and estimated glomerular filtration rate. 6) General Security (report side effects, serious side effects and treatment discontinuation due to side effects);Timepoint(s) of evaluation of this end point: 24 weeks | — |
