A Study of Three Different Anti-HIV Drug Combinations in HIV-Infected Patients

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: November 1998
The purpose of this study is to compare the safety and effectiveness of three anti-HIV drug combinations. The three combinations are: (1) efavirenz (DMP 266) plus indinavir; (2) DMP 266 plus zidovudine (ZDV) plus lamivudine (3TC); and (3) indinavir plus ZDV plus 3TC. This study also examines the resistance HIV may have to these drugs and if these drugs are effective over a long period of time.

Condition Intervention Phase
HIV Infections
Drug: Indinavir sulfate
Drug: Lamivudine
Drug: Zidovudine
Phase 3

Study Type: Interventional
Study Design: Primary Purpose: Treatment
Official Title: A Phase III, Multicenter, Randomized, Open-Label Study to Compare Antiretroviral Activity and Tolerability of Three Different Combination Regimens (DMP 266 + Indinavir, DMP 266 + Zidovudine + Lamivudine, Indinavir + Zidovudine + Lamivudine) in HIV-Infected Patients

Ages Eligible for Study:   13 Years to 60 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Exclusion Criteria

Concurrent Medication:


  • Terfenadine, astemizole, cisapride, triazolam, or midazolam (competition for the enzyme cytochrome P-450 3A4 [CYP3A4] by indinavir could result in inhibition of metabolic breakdown of these drugs and create the potential for serious and/or life threatening events [i.e., cardiac arrhythmia, prolonged sedation]).
  • Rifampin or rifabutin (prohibited because of potential drug interaction with indinavir).
  • Ketoconazole, itraconazole, and clarithromycin.
  • Concomitant systemic therapy for acute opportunistic infection or malignancy.


Life expectancy less than 12 months.

Prior Medication:


  • Prior treatment with efavirenz, 3TC, an NNRTI, or an HIV protease inhibitor.
  • Prior antiretroviral agent within 14 days of initiating study treatment.
  • Prior treatment (within 30 days of initiating study treatment) with any other experimental drug for any indication.

Patients must:

  • Have a diagnosis of HIV infection.
  • Have CD4 counts greater than or equal to 50 cell/mm3.
  • Have a life expectancy greater than or equal to 12 months.
  • Be post-pubescent.
