History of Changes


The purpose of this study is to determine the effect of treatment with Trizivir (TZV) plus efavirenz (EFV) or TZV alone on viral load (level of HIV in the blood).

Condition Intervention Phase
HIV Infections

Drug : Abacavir sulfate, Lamivudine and Zidovudine
Drug : Efavirenz
Phase 4

Study Type: Interventional
Study Design: Primary Purpose: Treatment
Official Title: A Phase IV Multicenter Study of the Efficacy and Safety of 48-Week Induction Treatment With TRIZIVIR (Abacavir 300 Mg/Lamivudine 150 Mg/Zidovudine 300 Mg Combination Tablet BID) With Efavirenz (600 Mg QD) Followed by 48-Week Randomized, Open-Label, Maintenance Treatment With TRIZIVIR With or Without Efavirenz in HIV-1 Infected Antiretroviral Therapy Naive Subjects

Estimated Enrollment: 400
Study Start Date: February 2001

Detailed Description:

Patients receive TZV plus EFV in the 48-week Induction Phase. Eligible patients, defined as those with plasma HIV-1 RNA under 50 copies/ml, participate in the 48-week Maintenance Phase. Patients are randomized equally to receive either TZV plus EFV or TZV alone.
An immunology substudy will be conducted, including approximately the first 100 patients enrolled who agree to participate.
