  Purpose

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.


Condition Intervention Phase
HIV-1
 Drug: fosamprenavir/ritonavir (700mg/100mg BID)
Drug: fosamprenavir/ritonavir (1400mg/100mg BID)
Drug: fosamprenavir/lopinavir/ritonavir (1400mg/533mg/100mg BID)
 Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Endpoint Classification: Safety/Efficacy Study
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: A Phase III, Randomized, Controlled, Open-Label, Multicentre, Three Arm Study to Compare the Efficacy and Safety of a Dual-Boosted HIV-1 Protease Inhibitor Regimen of Fosamprenavir/Lopinavir/Ritonavir 1400mg/533mg/133mg Twice Daily and an Increased Dosage Regimen of FPV/RTV 1400mg/100mg BID Versus the Standard Dosage Regimen of FPV/RTV 700mg/100mg BID for 24 Weeks in Multiple-PI Experienced, HIV-Infected Adults Experiencing Virological Failure

Further study details as provided by GlaxoSmithKline:

Primary Outcome Measures:
  • The average area under the curve minus baseline [AAUCMB] in plasma HIV-1 RNA at 24 Weeks when each are administered in combination with an optimised background therapy, in a multiple PI-experienced population experiencing virological failure. [ Time Frame: 24 weeks ]

Secondary Outcome Measures:
  • Efficacy (AAUCMB) at 48 weeks, safety, tolerability(incidence and nature of AEs and laboratory abnormalities) at week 24 and 48, CD4 change from baseline at week 24 and 48, and the steady-state plasma APV and LPV through concentrations. [ Time Frame: 48 weeks ]

Estimated Enrollment: 150
Study Start Date: March 2005
  Eligibility

Ages Eligible for Study:   18 Years and older
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Criteria

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.
