Bristol-Myers Squibb Identifier:
First received: June 29, 2005
Last updated: April 8, 2011
Last verified: April 2011
The purpose of this study is to evaluate whether a therapy with an all once daily regimen of efavirenz (EFV), didanosine (ddI)-EC and lamivudine (3TC) leads to improved outcomes, as measured by viral load, CD4 counts, adherence, safety, and tolerability.

Condition Intervention
HIV Infections
Drug: efavirenz; didanosine EC; lamivudine

Study Type: Interventional
Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Daily Antiretroviral Therapy (DART 1): An Open-Label, Single-Arm, Prospective, Multicenter Clinical Trial to Evaluate the Efficacy and Safety of Didanosine Enteric Coated (Ddl-EC) in Combination With Lamivudine (3TC) and Efavirenz (EFV) Once Daily in Anti-Retroviral Therapy (ART) Naive HIV-Infected Patients

Further study details as provided by Bristol-Myers Squibb:

Primary Outcome Measures:
  • Estimate efficacy of ddI-EC/3TC/EFV given QD determined by proportion of patients with plasma HIV-1 RNA <400 copies/mL at 48 weeks

Secondary Outcome Measures:
  • Evaluate proportion of patients with plasma HIV RNA <400 copies/mL at Weeks 24, 48, 72, and 96.
  • Evaluate proportion of patients with plasma HIV RNA <50 copies/mL at Weeks 24, 48, 72, and 96
  • Determine viral suppression of plasma HIV RNA from change in baseline at week 48
  • Determine proportion of patients whose HIV viral load doesn't drop to undetectable level within 24 weeks
  • Evaluate time to undetectable plasma HIV RNA
  • Evaluate proportion of patients demonstrating virologic breakthrough
  • Evaluate proportion of patients demonstrating virologic failure
  • Evaluate time to virologic breakthrough and virologic failure
  • Measure magnitude and durability of changes in CD4 cell counts
  • Evaluate patient adherence with QD regimen using pill counts and AMAF
  • Determine pattern and emergence of HIV genotype resistance mutations in patients experiencing virologic failure
  • Explore QoL changes using MOS-HIV health survey
  • Evaluate safety and tolerability of QD regimen

Estimated Enrollment: 65
