Comparing FTC and Lamivudine in HIV-Infected Patients on a Stable Anti-HIV Drug Combination
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
The purpose of this study is to compare two anti-HIV drugs, FTC and lamivudine (3TC), when given with either stavudine (d4T) or zidovudine (ZDV) and one other anti-HIV drug.
Condition or disease
Drug: EmtricitabineDrug: Lamivudine
Patients are randomized to one of two arms in a 2:1 ratio (weighted to Arm 1). Arm 1: Replace lamivudine with FTC while continuing on current background regimen. Arm 2: Continue on current lamivudine-containing regimen. Patients are further stratified based upon screening plasma HIV-1 RNA and background therapy. Stratum 1: Less than 50 copies/ml; PI (protease inhibitor) in treatment regimen. Stratum 2: Less than 50 copies/ml; NNRTI (nonnucleoside reverse transcriptase inhibitor) in treatment regimen. Stratum 3: 50-400 copies/ml; PI in treatment regimen. Stratum 4: 50-400 copies/ml; NNRTI in treatment regimen. Clinic visits occur at regular intervals throughout the 48-week study period to determine viral load.
A Randomized, Open-Label Equivalence Study of FTC Versus Lamivudine in Patients on a Stable Triple Antiretroviral Therapy Regimen Containing Lamivudine, Stavudine or Zidovudine, and a Protease Inhibitor or Non-Nucleoside Reverse Transcriptase Inhibitor
