  • Number of Participants With Any Adverse Event (AE): Interim Analysis [ Time Frame: Baseline (Day 1) up to 31 January 2006 (up to Week 264) ] [ Designated as safety issue: No ]
    An AE is defined as any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product and which does not necessarily have a causal relationship with this treatment. A list of all adverse events is reported in the "Other (Non-Serious) Adverse Events" section.

  • Change From Baseline in the Indicated Clinical Chemistry Parameters at Weeks 48, 96, 120, 132, 168, 180, 204, and 216 [ Time Frame: Baseline (Day 1) and Weeks 48, 96, 120, 132, 168, 180, 204, and 216 ] [ Designated as safety issue: No ]
    Fasting blood samples of participants were collected for the assessment of triglycerides (Tri.), cholesterol (Chol.), high density cholesterol (HDL), low density cholesterol (LDL), and fasting blood glucose (FBG). Change from Baseline at Weeks (W) 48, 96, 120, 132, 168, 180, 204, and 216 was calculated as the value at that particular week minus the value at Baseline (Day 1).

  • Percentage of Participants With Plasma HIV-1 Ribonucleic Acid (RNA) <400 and <50 Copies Per Milliliter at Baseline and Weeks 48, 120, 180, and 216 (MD=F and Observed) [ Time Frame: Baseline and Weeks 48, 120, 180, and 216 ] [ Designated as safety issue: No ]
    Blood samples of participants were collected for the assessment of HIV-1RNA copies in plasma. Viral load, measured in RNA copies per milliliter of plasma, is an efficacy measure for antiretroviral drugs. In the MD=F analysis, participants who had missing data at or had discontinued the study prior to a certain time point are classified as non-responders. In the observed analysis (OA), data are presented for the number of participants still enrolled in the study at a certain time point. Participants in the NFV populations had received antiretroviral therapy prior to Baseline.

    The number of participants with progression of HIV-1 disease were assessed using the CDC classification of HIV-1: class A, asymptomatic or lymphadenopathy; class B: symptomatic, but not AIDS; class C, AIDS. A participant is considered to have had a disease progression if they report a CDC Class C event for the first time, if they report a new CDC Class C event, or if they experience any fatal adverse event during the study.

A Study To Assess GW433908 (Fosamprenavir) Containing Regimens In HIV-1 Infected Subjects
An Open-Label Phase III Study to Assess the Long Term Safety Profile of GW433908 Containing Regimens in HIV-1 Infected Subjects

GW433908 (fosamprenavir; FPV)is a pro-drug of amprenavir (APV) which is more water soluble and can be formulated into a tablet with a reduced pill burden (four 700mg tablets of FPV versus sixteen 150mg capsules daily for APV. This study is designed to provide additional information on long term safety and tolerability of FPV containing regimens for those subjects who received FPV in previous GlaxoSmithKline studies.

ViiV Healthcare is the new sponsor of this study, and GlaxoSmithKline is in the process of updating systems to reflect the change in sponsorship.
