- Switching to LPV/r monotherapy is effective, safe and well tolerated through 96 weeks
Design :
Endpoint :
- Primary endpoint: proportion of patients with HIV-1 RNA < 80 c/mLat W96 (ITT, missing equals failure analysis)
- Secondary endpoints: virologic failure (2 consecutive HIV-1 RNA> 500 c/mL), AIDS-defining illnesses, CD4, safety, adverse events
Baseline characteristics and patient disposition :
Virologic outcome :
Virologic outcome :
- 1 virologic failure (confirmed HIV-1 RNA > 500 c/mL) in each group. No resistance mutation on genotype
- No difference in CD4 changes between groups
- GI adverse events more frequent in the monotherapy group: 24 vs 10(p = 0.001)
- 5 patients in the triple therapy group underwent regimen changes due to drug-related toxicities
