A Clinical Trial of Alternating and Intermittent Regimens of 2',3'-Dideoxycytidine and 3'-Azido-3'-Deoxythymidine in the Treatment of Patients With AIDS and Advanced ARC
In Brief
A clinical study evaluating Zidovudine and Zalcitabine for HIV Infections. Completed, across 1 site.
Detailed Summary
To determine if alternating zidovudine (AZT) and zalcitabine (dideoxycytidine; ddC) (first one and then the other) or intermittent therapy (1 week of drug then 1 week off) will lessen the toxic effects of either drug alone, while still inhibiting HIV (the AIDS virus) in patients with AIDS or AIDS related complex. AZT extends the survival of some patients with AIDS, and both AZT and ddC are known to inhibit the growth of HIV. When AZT or ddC is given continuously over a prolonged period of time, toxic effects occur that are not found when the drugs are given for 4 - 6 weeks. It is hoped that by alternating the drugs or by giving one drug intermittently, the toxic effects can be decreased without lowering the therapeutic effectiveness of the drugs.
