Brief summary
The aim of this study was to assess whether TRIZIVIR, administered twice-daily was as safe, tolerable and efficacious as a combination of the drugs COMBIVIR administered twice-daily and atazanavir administered once daily. Over the course of 48 weeks, various parameters that measure safety, tolerability and efficacy of the investigational drugs were measured and compared.
Detailed description
A Phase IV Randomized, Multicenter, Open-Label Study to Compare the Safety, Tolerability and Efficacy of Trizivir (abacavir 300mg, lamivudine 150mg, and zidovudine 300mg) BID vs Combivir (lamivudine 150mg and zidovudine 300mg) BID plus atazanavir 400mg QD in Antiretroviral Naive HIV-1 Infected Subjects over 48 Weeks

Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The primary endpoint was drug efficacy, measured as the proportion of study subjects who had plasma HIV-1 RNA less than 50 copies/mL at week 48 and did not meet the definition of virologic failure through this timepoint. | 48 Weeks |
Secondary
| Measure | Time frame |
|---|---|
| % patients with plasma HIV-1 RNA <50 and <400 copies/mL at weeks 24 & 48; Change from BL in plasma HIV-1 RNA and CD4+ measures; AEs; Time to virologic failure | 48 Weeks |
