A Comparison of Two Drug Combinations Used in HIV-Infected Patients Who Never Have Taken Anti-HIV Drugs - Full Text View

Sponsor:	Gilead Sciences
Information provided by:	NIH AIDS Clinical Trials Information Service
ClinicalTrials.gov Identifier:	NCT00005573

Purpose

The purpose of this study is to compare the effectiveness of treatment with tenofovir DF (TDF) plus lamivudine (3TC) plus efavirenz (EFV) with that of stavudine (d4T) plus 3TC plus EFV in HIV-infected patients who previously have not used anti-HIV drugs.

Condition	Intervention	Phase
HIV Infections	Drug: Tenofovir disoproxil fumarate Drug: Efavirenz Drug: Lamivudine Drug: Stavudine	Phase III

Study Type:	Interventional
Study Design:	Treatment, Parallel Assignment
Official Title:	A Phase 3, Randomized, Double-Blind, Multicenter Study of the Treatment of Antiretroviral-Naive, HIV-1-Infected Patients Comparing Tenofovir Disoproxil Fumarate Administered in Combination With Lamivudine and Efavirenz Versus Stavudine, Lamivudine, and Efavirenz

Estimated Enrollment:	600
Study Start Date:	March 2000

Detailed Description:

Patients will be stratified on the basis of HIV-1 RNA levels (greater than 100,000 copies/ml or less than or equal to 100,000 copies/ml) and CD4 count (less than 200 cells/mm3 or greater than or equal to 200 cells/mm3). Treatment-naive patients with HIV-1 RNA levels greater than 5,000 copies/ml will be randomized 1:1 to 1 of 2 treatment arms:

Group 1: TDF + d4T placebo + 3TC + EFV Group 2: TDF placebo + d4T + 3TC + EFV TDF/placebo and d4T/placebo will be administered in a blinded fashion. 3TC, EFV, and nevirapine (administered in the event of EFV-associated CNS toxicity) will be administered in open-label fashion. Patients will be monitored for safety using periodic physical examinations, serial laboratory tests, and bone densitometry tests. Additionally, changes in plasma HIV-1 RNA levels and CD4 cell counts will be monitored to assess antiviral efficacy. At the end of Week 48, patients without dose-limiting toxicity will have the option to roll over into open-label extended dosing until tenofovir DF is commercially available or Gilead Sciences terminates the study. Only open-label tenofovir DF will be provided beyond Week 48.
