A Study to Compare the Effectiveness of Different Anti-HIV Drug Regimens in Keeping Levels of HIV in the Blood as Low as Possible

• Status: Completed
• Trial end date: 2000-01-01
• Target enrollment: 0
• Participant gender: All

Summary

This study will look at different anti-HIV drug regimens to see which works best to keep the level of HIV (viral load) in the blood as low as possible during maintenance therapy. You will be assigned randomly (like tossing a coin) to 1 of 3 groups:

Group 1: Didanosine plus stavudine plus hydroxyurea (ddI/d4T/HU). Group 2: Didanosine plus stavudine plus efavirenz (ddI/d4T/EFV). Group 3: This group of patients will remain on their current drug regimens. This study will last approximately 3 years; you will receive study medications for the duration of the study.

Anti-HIV drug regimens that include protease inhibitors (PIs) are very good at lowering viral load. However, some patients have a rise in HIV levels while on PI maintenance. It may be possible to keep HIV levels low using another class of drugs for maintenance that are easier to take and less expensive than PIs. If viral load increases while a patient is taking this second group of drugs, it may be possible to restart the PI drug regimen and again decrease HIV levels.

• Phase: Phase 2
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: National Institute of Allergy and Infectious Diseases (NIAID)
• Treatments: Didanosine; Efavirenz; HIV Protease Inhibitors; Hydroxyurea; Protease Inhibitors; Stavudine

• Are at least 13 years old (need consent if under 18).

• Are HIV-positive.

• Are taking your first anti-HIV drug regimen, which must include a PI and at least one NRTI (nucleoside reverse transcriptase inhibitor) and have been on this regimen for at least 12 months.

• Have a viral load less than 400 copies/ml for at least 12 months prior to study entry, and have a viral load less than 50 copies/ml within 60 days of study entry.

• Have a CD4 cell count of at least 200 cells/mm3 within 60 days of study entry.

• Are willing to go back on the drugs you are currently on, if necessary.

• Are willing to use effective methods of birth control during the study and for 3 months after.

Exclusion Criteria

You will not be eligible for this study if you:
