A 72-week Randomized Clinical Trial Comparing the Safety and Efficacy of Three Initial Antiretroviral Regimens -GPO-VIR S (d4T/3TC/NVP) for 24 Weeks Followed by GPO-VIR Z (AZT/3TC/NVP) vs GPO-VIR Z vs TDF/FTC/NVP

  Purpose

This protocol aims to determine the risk/benefits of this policy by comparing head-to-head a regimen of GPO-VIR Z or TDF/FTC/NVP for 18 months in ARV-naïve patients to a 6-month lead in with GPO-VIR S followed by 12 months of GPO-VIR Z. The primary outcomes to be assessed will be anemia, neuropathy, lipoatrophy and renal function.

Detailed Description:

GPO-VIR Z is a new combination antiretroviral (ARV) medication that substitutes zidovudine (AZT) for stavudine (d4T) from the original formulation of GPO-VIR S. This new combination should decrease rates of lipoatrophy and neuropathy which are side-effects strongly linked to the use of d4T. However, there is some risk that initiating therapy with an AZT- containing regimen may cause unacceptable rates of anemia. Many Thai physicians have adopted a practice of using 6 months of the stavudine-containing GPO-VIR S as a lead in before introducing AZT-containing GPO-VIR Z in an effort to balance the risks and benefits of these two medications. There are no definitive data, however, that can attest to the benefit of such an approach.
