In HIV-1 infected adults receiving first line ART with TDF+XTC+EFV or DTG+XTC+TDF virologically suppressed (viral load < detection limit of the technique used) for at least two years: to assess the non-inferiority of a strategy consisting of switching to a dual maintenance therapy (DTG+ 3TC or ATV/r+3TC), comparing to WHO standard first line regimen (TDF+3TC+EFV or DTG+3TC+TDF), in terms of virological success at 96 weeks, in Cameroon, Côte d'Ivoire and Burkina Faso.~This is a trial including two strategies (dual maintenance therapy and triple reference therapy) and three ART regimens (DTG+3TC and ATV/r+3TC used in the maintenance strategy and TDF+3TC+EFV/ DTG+3TC+TDF used in the reference strategy).~The primary analysis will compare the two strategies. Secondary analyses will compare the three ART regimens two by two.~In order to make these secondary analyses possible, participants will be randomly assigned, at inclusion, to each of the three ART regimens (arm 1: DTG+3TC; arm 2: ATV/r+3TC; arm 3: TDF+3TC+EFV / DTG+3TC+TDF). The maintenance strategy will include arm 1 and 2. The reference strategy will include arm 3~Number of participants : 480 (160 in each ART regimen, ie 320 in the dual maintenance therapy strategy and 160 in the triple therapy reference strategy)~The primary endpoint is treatment success, as defined by using the FDA snapshot algorithm : patients who are still continuing the assigned strategy and whose last available plasma HIV-1 RNA in the the window analysis (90 to 102 weeks) is <50 copies/ml at the end of the window analysis (90 to 102 weeks)
MODERATO is a phase III, open-label, randomized, multicenter, non-inferiority trial conducted in West and Central Africa (Cameroon, Côte d'Ivoire, Burkina Faso).~HIV-1 infected adults receiving first line ART with TDF+XTC+EFV or DTG+XTC+TDF virologically suppressed will be recruited and followed during 100 weeks.~The objective is to assess the non-inferiority of a strategy consisting of switching to a dual maintenance therapy (DTG+3TC or ATV/r+3TC), comparing to WHO standard first line regimen (TDF+3TC+EFV or DTG+3TC+TDF), in terms of virological success at 96 weeks
