Study 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.

What researchers measure

Primary outcomes

  1. 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.

    Time frame: 48 Weeks

Secondary outcomes

  1. % 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

    Time frame: 48 Weeks
