A Study of Indinavir Taken With or Without DMP 266

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: July 1998
The purpose of this study is to see if it is safe and effective to add DMP 266 to an anti-HIV treatment program of indinavir and nucleoside reverse transcriptase inhibitors (NRTIs).

Condition Intervention Phase
HIV Infections Drug: Indinavir sulfate Drug: Efavirenz Phase 3

Study Type: Interventional
Study Design: Intervention Model: Parallel Assignment
Primary Purpose: Treatment
Official Title: A Phase III, Double-Blind, Placebo-Controlled, Multicenter Study to Determine the Effectiveness and Tolerability of the Combination of DMP 266 and Indinavir Versus Indinavir in HIV-Infected Patients Receiving Nucleoside Analogue (NRTI) Therapy

Further study details as provided by NIH AIDS Clinical Trials Information Service:

Estimated Enrollment: 300
Detailed Description:

In this double-blind, placebo-controlled study, 300 patients are randomized to 1 or 2 reverse transcriptase inhibitors of their choice plus blinded therapy on Arm A or B as follows:

Arm A: DMP 266 placebo plus indinavir. Arm B: DMP 266 plus indinavir. After 16 weeks, patients may switch the NRTI portion of their regimen if they meet a treatment failure criterion. After the completion of the 24-week period, patients have the option to continue on open-label DMP 266 and indinavir.


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

Inclusion Criteria

Patients must have:

  • CD4+ cell count of at least 50 cells/mm3.
  • HIV RNA level of at least 10,000 copies/ml by reverse transcriptase polymerase chain reaction (RT-PCR, Amplicor test kit) at screening.
  • Signed, informed consent from parent or legal guardian for patients less than 18 years of age.

Exclusion Criteria

Prior Medication:


  • DMP 266.
  • Other nonnucleoside reverse transcriptase inhibitors.


One or two NRTIs (except ZDV and d4T in combination) for a minimum of 8 weeks, within 12 weeks prior to screening.
