First-line ART – ACTG A Study
Approval was obtained from each participating sites’ institutional review board for the main study and the substudy. Eric Daar noted that many of these were abacavir hypersensitivity reactions [HSR], as HLA screening was not in standard practice at the time. The chronic phase of untreated HIV infection is characterized by viral replication resulting in a dynamic equilibrium between viral production and clearance, with approximately one-half of the circulating virus replaced daily with newly produced avtg.
Support Center Support Center. Daar Act et al. It may have been superseded by more recent developments. Both regimens seemed equally effective. In the overall ACTG A study population, the relationship between change in viral catg from entry to week 4 and time to virologic failure was evaluated with univariate and multivariable Cox proportional hazards models.

However, when a regimen failed, users of atazanavir-ritonavir were less likely than efavirenz users to develop resistance to nukes.

If you have or suspect you may have a health problem, consult your health care provider. In this protocol-specified secondary analysis of ACTG A and its viral load substudy, we found no significant difference in early viral load change between the NRTI arms, including in the high 2502 load stratum.
CollierMD, 5 Margaret A. The Data Safety Monitoring Board DSMB overseeing the study recommended that the nuke portions of the study be unblinded and participants then had the option of continuing to take their assigned nukes or changing them. We found a smaller week 4 virologic response was associated with an increased risk for subsequent virologic failure.
Conclusions — Comparing Atazanavir and Efavirenz Here are some of the conclusions that the ACTG team arrived at when comparing atazanavir-ritonavir to efavirenz:
