Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

To show that zalcitabine (dideoxycytidine; ddC) is at least as effective as zidovudine (AZT) in the treatment of AIDS or advanced AIDS related complex (ARC), and also that ddC shows a different safety profile than AZT. In clinical studies, ddC shows antiviral activity. Because of the antiviral activity, and because of the low incidence of mild, reversible neurotoxicity and absence of blood-related toxicity with low dose ddC therapy, a long-term Phase II/III study comparing ddC to AZT in patients with AIDS or advanced ARC is now warranted.
