A Multicenter Dose Ranging Clinical Trial of 2',3'-Dideoxycytidine in the Treatment of Patients With AIDS and Advanced ARC.
To evaluate the long-term safety and effectiveness of the drug 2',3'-dideoxycytidine ( zalcitabine; ddC ) in treating patients with AIDS or advanced AIDS related complex ( ARC ).
Recent studies show that a certain group of drugs (dideoxynucleosides) are effective in treating patients with HIV infection. ddC is a dideoxynucleoside and test tube studies show that it may be valuable in treating AIDS patients. ddC has been shown to be well tolerated in certain patients with AIDS.
Study Overview
Detailed Description
Recent studies show that a certain group of drugs (dideoxynucleosides) are effective in treating patients with HIV infection. ddC is a dideoxynucleoside and test tube studies show that it may be valuable in treating AIDS patients. ddC has been shown to be well tolerated in certain patients with AIDS.
A range of doses of ddC is given to patients with AIDS and ARC. Eight patients with AIDS and eight patients with ARC are given ddC at the lowest level for 12 weeks. Patients who respond with a rise in their number of T4 cells or with a fall in HIV antigen in their serum (the fluid portion of the blood) are continued at that dose for an additional 12 weeks. Patients who do not respond at a given dose level (no rise in T4 or fall in serum HIV antigen) stop treatment at 12 weeks. All patients are followed off therapy for 4 weeks. As each dose level is found to be well tolerated for 10 weeks in five of the eight patients in each group, additional patients will be entered at higher dose levels until eight AIDS and eight ARC patients are receiving the drug at a given level.
