Third Line Antiretroviral Treatment Optimization in Sub-Saharan Africa (THILAO)

Main objective

To estimate, in sub-Saharan African HIV-1 infected adults who failed a NNRTI-base first-line ART and then a PI-based second-line ART:

1. The efficacy (and associated factors) at 12 weeks of an intensive 3-months adherence reinfrocement phase;
2. In patients who successfully resuppress at 12 weeks: The percentage of patients still with continuing succesfull virologic supression on 2nd-line ART at 64 weeks (and factors associated to success) ;
3. In patients with persistent failure at 12 weeks : The efficacy (and associated factors) at 64 weeks of a darunavir/r + raltegravir-based 3rd-line regimen.

Number of participants : 200

Main outcome :

• At 12 weeks : Proportion of patients with a plasma HIV-1 RNA <400 copies/ml and/or with a decrease in plasma HIV-1 RNA >2 log10 copies/ml between inclusion and 12 weeks;
• At 64 weeks : proportion of patients with a plasma HIV-1 RNA <50 copies/ml.

Inclusion criteria:

• Age >18 years
• Documented HIV-1 infection.
• History of failing a NNRTI-based 1st-line ART
• Current PI-based 2nd-line ART >6 months
• Plasma HIV-1 RNA >1000 copies/ml
• Signed informed consent
