The Switch Study: The Role of Lamivudine/Emtricitabine (3TC/FTC) in Antiretroviral Regimens

Summary

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.
