For HIV-infected individuals with highly resistant viruses, higher drug levels may be required to block the virus. This study investigates that concept by comparing the efficacy of standard fosamprenavir/ritonavir to an increased dose of boosted fosamprenavir and to a combination of fosamprenavir (increased dose)/lopinavir/ritonavir.

Inclusion criteria:

• Multiple protease-inhibitors experienced HIV-1 infected individuals experiencing virological failure and who's virus is not fully resistant to boosted fosamprenavir and boosted lopinavir based on genotypic resistance tests.

Exclusion criteria:

• No full resistance to FPV/r or LPV/r
• Planned use of NNRTIs as part of the study salvage regimen
• Application of additional exclusion criteria as determined by physician.
