- After induction with ritonavir-boosted ATV, switching to unboosted ATV shows non-inferior efficacy and a more favourable safety profile than a triple combination regimen based on boosted ATV for up to 48 weeks
- Switching to ATV might represent a feasible treatment optionin patients with virologic suppression on ATV/r

Design :
Endpoints :
- Primary: non inferiority in the proportion of patients with HIV-1 RNA < 50 c/mL at W48 of the maintenance phase (non completer = failure, intent-to-treat analysis), lower limit of the 95% CI for the difference = - 15%, 80% power)
- Secondary: treatment failure, CD4, fasting lipids, adverse events
Baseline characteristics and patient disposition :

Outcome at week 48 of the maintenance phase

Other endpoints
- Virological rebound(HIV-1 RNA ≥ 50 c/mL)
- Time to treatment failure or to virological rebound not significantly different between the 2 groups
- Serious adverse events
- ATV/r: 3 (4%)
- ATV: 4 (5%)
Lipid changes and adverse events during maintenance phase :
