This study has been completed.
Information provided by:
NIH AIDS Clinical Trials Information Service Identifier:
First received: November 2, 1999
Last updated: June 23, 2005
Last verified: March 2000
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 Intervention Phase
HIV Infections Drug: Emtricitabine Drug: Lamivudine Phase 3

Study Type: Interventional
Study Design: Primary Purpose: Treatment
Official Title: 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

Estimated Enrollment: 390
Detailed Description:
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.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria
