Study of Once-Daily Versus Twice-Daily Fosamprenavir Plus Ritonavir, Administered With Abacavir/Lamivudine Once-Daily in Antiretroviral-Naive HIV-1 Infected Adult Subjects.
In Brief
A Phase 3 clinical trial evaluating fosamprenavir/ritonavir for Infection, Human Immunodeficiency Virus I and HIV-1 Infection. Completed, enrolled 212 participants across 69 sites in 9 countries.
Detailed Summary
This is a Phase IIIB, 48 Week, multicentre, randomized, open-label, parallel group study comparing the safety and efficacy of fosamprenavir plus ritonavir 1400mg/100mg once-daily to fosamprenavir plus ritonavir 700mg/100mg twice-daily, both administered with abacavir/lamivudine 600mg/300mg once-daily in antiretroviral-naive HIV-1 infected adults. This study utilizes a group-sequential design with two stages: 1) an interim 24 week cohort analysis of approximately 200 subjects and 2) if study continuation criteria are met at this interim analysis, further enrolment of an additional 528 subjects, followed over a minimum of 48 weeks. The objectives of the study are to demonstrate 1) non-inferior antiviral activity of fosamprenavir/ritonavir 1400mg/100mg QD compared to fosamprenavir/ritonavir 700mg/100mg BID and 2) a superior fasting non-HDL lipid profile in subjects receiving fosamprenavir/ritonavir 1400mg/100mg QD.
