Third Line Antiretroviral Treatment Optimization in Sub-Saharan Africa (THILAO)
Systematic "Adherence Intervention" Phase Before Switching to 3rd-line ART in Patients With 2nd-line ART Virologic Failure in Sub-Saharan Africa : a Phase 2b Non-randomized Study.
Thilao is a multi-country, phase 2b, non-randomized study, in Burkina Faso, Cote d'Ivoire, Mali and Senegal, West Africa.
HIV-1 adults with 2nd-line ART virologic failure (plasma HIV-1 RNA >1000 copies/ml) will be recruited and followed in two phases:
- First, a 12-week intentive adherence reinforcement phase, during which patients will continue 2nd-line ART, be seen repeatidly for counseling and educational training on adherence, and be offered the possibility of phone, SMS and home visit contacts with social workers;
Second, a 48-week phase, during which:
- Patients successfully resuppressed at the end of the first phase will continue 2nd-line ART and adherence reinforcement;
- Patients with persitent virologic failure will switch to a darunavir/r + raltegravir-based 3rd-line ART.
Genotype resistance tests will be performed retrospectively on frozen samples. The main outcome will be the percentage of patients with plasma HIV-1 viral RNA <50 copies/ml at 64 weeks.

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:
- The efficacy (and associated factors) at 12 weeks of an intensive 3-months adherence reinfrocement phase;
- 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) ;
- 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
