Clinical Trial Summary

To determine the safety and usefulness of zidovudine (AZT) for the treatment of patients with early symptomatic HIV infection or early AIDS related complex (ARC). The ability of AZT to suppress HIV, to improve body defenses, and to prevent the occurrence or development of AIDS or advanced ARC is being evaluated. In one human study, patients with AIDS or advanced ARC who received AZT had fewer life-threatening infections, improved in weight and performance, and lived longer than patients who received a placebo (inactive medication). Further studies are needed because toxic effects associated with the use of AZT were noted and the long-term effectiveness and toxicity of AZT are still unknown. It is also unknown if AZT will benefit patients with less severe HIV infections such as early ARC or PGL.


Clinical Trial Description

In one human study, patients with AIDS or advanced ARC who received AZT had fewer life-threatening infections, improved in weight and performance, and lived longer than patients who received a placebo (inactive medication). Further studies are needed because toxic effects associated with the use of AZT were noted and the long-term effectiveness and toxicity of AZT are still unknown. It is also unknown if AZT will benefit patients with less severe HIV infections such as early ARC or PGL. Patients accepted into the study are randomly assigned to receive either AZT or placebo. Treatment continues for a minimum of 104 weeks beyond the time the last patient enters the study. If the study medication causes toxic effects, the dose is decreased or temporarily stopped, and if the toxic effects are severe, then the medication will be stopped permanently. Participants visit the clinic every 2 weeks during the first 16 weeks and once a month thereafter. Throughout the study frequent blood samples are taken to monitor the effectiveness and safety of the treatment. AMENDED: The placebo arm has been discontinued as of August 3, 1989 and the AZT dose has been reduced. ;
