The Role of 3TC/FTC in Partially Suppressive Antiretroviral Regimens: The Switch Study

In this study the researchers will be enrolling patients who are failing their current antiretroviral regimen who also have resistance to 3TC or FTC. Patients will have their current antiretroviral regimen changed based on resistance testing and also be randomly assigned to either include, or not include 3TC/FTC in this new regimen. The purpose of the research is to investigate whether the change in therapy results in a decrease in the amount of virus particles and an increase in the CD4 cell count. In addition the researchers are investigating the relationship between the existence of resistance and the rate of decrease in viral load, and also to determine if continuing 3TC/FTC (despite being resistant to the medications) has any effect on the rate of decrease of viral load, or effect on CD4 counts.

NCT00152061 HIV Infections
MeSH: HIV Infections

1 Interventions

Name: 3TC and FTC

Type: Drug


Primary Outcomes

Measure: To evaluate the role of lamivudine, (3TC), and emtricitabine, (FTC), in salvage regimens in patients with prior 3TC/FTC use, documented resistance to 3TC/FTC, and ongoing viremia as assessed by:

Measure: Impact on the initial rate of change in HIV-1 viral load after removing 3TC/FTC from the failing regimen, and

Measure: Overall change from baseline in HIV-1 viral load at 24 weeks (HIV-VL AUC 24 wks).

Secondary Outcomes

Measure: To evaluate the impact of continued versus discontinued 3TC/FTC on the prevalence, frequency and dynamics of the M184V/I amino acid substitution over 24 weeks.

Measure: To determine the proportion of patients failing and/or not responding to therapy after 24 weeks as defined by failure to achieve HIV-1 viral load less than 400 copies/ml and/or less than 50 copies/ml

Measure: To assess the changes from baseline in absolute CD4 (and CD8) cell counts at 24 weeks.

Purpose: Treatment

Allocation: Randomized
