One of the both Funder partners decided to stop the study before the initiation : thus no product provided and no funding to realize the study

The primary objective of the study is to evaluate the capacity of Dolutegravir + Rilpivirine vs. continued triple combination HAART to maintain plasma HIV RNA ≤ 50 copies/ml throughout 24 weeks in patients with plasma HIV RNA ≤ 50 copies/mL for at least 2 years under conventional HAART (2 NNRTI + 3rd agent).

The main secondary objectives are the following:

• % of virologic success (plasma viral load ≤ 50 copies/mL) at W24 and W48
• % of patients who maintain a plasma viral load ≤ 50 copies / ml from D0 to W48
• % of virological failure defined by two consecutive plasma viral load > 50 copies/mL
• Profile of genotypic resistance in case of virological failure.

The trial will be conducted according to the design below, in 3 steps:

• Step 1: enrollment of 80 patients (40 in each arm)
• Step 2: enrollment on hold until W16 data from the 40 patients enrolled in the intervention arm have been analyzed.
• Step 3: resumption and completion of enrollment if conditions for resuming enrollment at the end of step 2 are fulfilled, i.e. if the percentage of patients randomized to the intervention arm who have a plasma viral load ≤ 50 copies/mL from D0 to W16 is significantly > 70%, which translates in a maximum of 6 virologic failures.

Inclusion Criteria:

• Age ≥ 18 years
• HIV-1 infection
• Treatment with suppressive triple HAART (2 NRTI + either 1 PI/r, or 1 NNRTI, or INI), unchanged for > 6 months, Intra-class substitution within past 6 months is not considered as a treatment change.

• CD4 cell count > 350/mm3 for > 6 months
• No prior virologic failure under an NNRTI-containing or an INSTI-containing ART regimen
