Study Endpoints

Primary Endpoints

Number of Subjects Needing to Switch Comparator Drugs (FPV/r or EFV)
96 weeks

Subjects were randomized and initiated treatment on one of the antiretroviral arms(FPV/r or EFV) at study Entry visit. Subjects would be switched for the follwing reasons: * To resolve a Grade 3 or 4 Adverse Event * The subject experienced a virologic failure (as defined in section 3.6.2) * The investigator believes the subject is at a significant risk for failing to comply with the protocol AND the investigator believes a regimen substitution is likely to resolve the compliance issue * The investigator believes there is any other significant safety concern for the subject associated with remaining on the current regimen (e.g., hypersensitivity reaction, increased risk of suicide)
