History of Changes

Purpose

The HIV-2 is less common ie 1-2 million people in West Africa. HIV-2 does have the same sensibility to antiretroviral treatment (ART) compared to HIV-1. The ART strategies that are appropriate for the HIV-1 infection are not as effective for HIV-2. Classical triple therapy including PI is less effective for HIV-2. Also, the choice of ARTs in a second line treatment is limited. The first line optimal treatment has to be defined by a prospective and randomized evaluation of other strategies. The primary endpoint will be adapted to the specificity of the HIV-2 infection. The 1st step is to define, with a phase II clinical trial, whether a strategy including 2 NRTIs and raltegravir, as an alternative strategy to the classical triple therapy, shows an immunovirological response, at least, as good as the one obtained with the triple therapy. The hypothesis is that the low ART response observed in HIV-2 infection is due to a low virological strength of the ARTs used and that the combination of 2 NRTIs and raltegravir should show a therapeutic success of at least 50% at week 48.

Primary Outcome Measures:

Proportion of participants in therapeutic success [ Time Frame: at Week 48 ] [ Designated as safety issue: Yes ]
The participants will be considered in therapeutic success at Week 48 if they did not present any of the following events:
- Plasma HIV-2 RNA load over or equal to 100 copies/mL, starting from Week 24 and confirmed within the next 4 weeks,
- CD4 lymphocytes gain below 100/mm3 at Week 48 compared to the CD4 lymphocytes counts average between Week-4 and Week 0,
- Raltegravir permanent discontinuation,
- Death from any cause,
- New B or C events confirmed by an endpoint review committee

Secondary Outcome Measures:

Gain in CD4 lymphocytes count [ Time Frame: between Week 0 and Week 12 ] [ Designated as safety issue: No ]
Tolerance of the treatment [ Time Frame: from Week 0 to Week 48 ] [ Designated as safety issue: Yes ]
- number, nature, severity and time to adverse event.
- evolution of the metabolic disorders, clinical and biological measurement
Evolution of the number and percentage of CD4 lymphocytes [ Time Frame: between Week 0 and Week 48 ] [ Designated as safety issue: Yes ]
Evolution of plasma HIV-2 RNA load [ Time Frame: between Week 0 and Week 48 ] [ Designated as safety issue: Yes ]
The rate of clinical progression will be defined as the switch [ Time Frame: from Week 0 to Week 48 ] [ Designated as safety issue: Yes ]
- from category A to B, C or death.
- from category B to C or death.
Adherence evaluated with ANRS self-administered questionnaire of adherence and plasma measurements of residual concentrations of antiretroviral drugs in viral failure cases [ Time Frame: from Week 0 to Week 48 ] [ Designated as safety issue: No ]
Description of the resistance mutations'profile in virological failure cases [ Time Frame: from Week 0 to Week 48 ] [ Designated as safety issue: Yes ]
Description of the resistance mutations'profile in virological failure cases (plasma HIV-2 RNA load over or equal to 100 copies/mL after plasma HIV-2 RNA load below 100copies/mL, confirmed with a retest within the 4 following weeks) with:
- the number and type of mutations in the RT and integrase genes compared to Week 0.
- the evolution of the phenotypic sensitivity of raltegravir and NRTIs compared to Week 0
Frequency of treatment switch or discontinuation [ Time Frame: from Week 0 to Week 48 ] [ Designated as safety issue: No ]
- overall (regardless of the molecule).
- for each study drug (raltegravir and emtricitabine/tenofovir disoproxil fumarate combination).
Evolution of plasma HIV-2 DNA load in PBMC [ Time Frame: at Week 24 and Week 48 and compared to those performed at Week 0 ] [ Designated as safety issue: No ]
Evolution of the quality of life [ Time Frame: from Week 0 to Week 48 ] [ Designated as safety issue: No ]
through PROQOL questionnaire
