Clinical Trial Summary

To determine the efficacy and safety of zidovudine ( AZT ) versus didanosine ( ddI ), AZT plus ddI, and AZT plus zalcitabine ( ddC ) in preventing disease progression in HIV-infected patients with CD4 counts of 200-500 cells/mm3.

Description:

Patients are randomized to receive AZT alone, AZT and ddI, AZT and ddC, or ddI alone for at least 2 years. Patients who develop AIDS or whose CD4 count falls to 50 percent or less of baseline are crossed over to another treatment arm.

PER AMENDMENT 4/5/95: Study treatment will be available until 10/31/95 at the latest for patients still taking study medications on 4/30/95, so that follow-up trials may be completed and approved.

Recruitment information / eligibility

• Status: Completed
• Enrollment: 2100
• Est. completion date: November 1995
• Accepts healthy volunteers: No
• Gender: All
• Age group: 12 Years and older

Eligibility

Inclusion Criteria
