NIH AIDS Clinical Trials Information Service Identifier:
First received: January 17, 2000
Last updated: June 23, 2005
Last verified: February 2000
The purpose of this study is to see if L-756423, an anti-HIV drug, is safe to give with indinavir and if it works well at lowering the level of HIV in the blood (viral load).

Condition Intervention Phase
HIV Infections
Drug: L-756423
Drug: Indinavir sulfate
Phase 2

Study Type: Interventional
Study Design: Primary Purpose: Treatment
Official Title: A Multicenter, Open-Label, Pilot Study to Evaluate the Safety and Activity of L-756423/Indinavir Sulfate, 800/400 Mg b.i.d. in Combination With Two nRTIs in HIV-Infected Patients Who Failed an Indinavir Containing Regimen

Estimated Enrollment: 30
Detailed Description:
All patients receive L-756423 plus indinavir plus two licensed nucleoside reverse transcriptase inhibitors (NRTIs), at least one to which the patient is naive. Patients remain on the drug regimen for 12 weeks (with possible extension to 16 weeks). Patients are evaluated with physical examinations and laboratory tests for blood and urine at Weeks 1, 2, 4, 6, 8, and 12 and two weeks post study. Plasma viral RNA is measured at Weeks 1, 2, 4, 6, 8, and 12. CD4 cell counts are measured at Weeks 2,4,8, and 12.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria

You may be eligible for this study if you:

  • Are HIV-positive.
  • Are at least 18 years old.
  • Have a viral load of at least 1,000 copies/ml.
  • Have a CD4 cell count of at least 100 cells/mm3.
  • Have experienced treatment failure (your viral load increased significantly) within 24 weeks of study entry while taking indinavir.

Exclusion Criteria

You will not be eligible for this study if you:

  • Are taking nonnucleoside reverse transcriptase inhibitors (NNRTIs).
