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. 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. After screening, physical examination and laboratory tests (within 14 days of entry) patients are randomized to one of two treatment groups. They receive either ddC plus an AZT placebo or AZT plus a ddC placebo. Because it is a blinded study, patients do not know which group they are in. Patients are evaluated weekly for the first 10 weeks and then biweekly thereafter.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
600 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How the interventions assigned to participants is kept confidential
Neither participants nor researchers know who is receiving which treatment. This is the most rigorous way to reduce bias, ensuring that expectations do not influence the results.

Other Ways to Mask Information
Open-label: Everyone knows which treatment is being given.
Single-blind: Participants do not know which treatment they are receiving, but researchers do.
Triple-blind: Participants, researchers, and outcome assessors do not know which treatment is given.
Quadruple-blind: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.

Eligibility

Researchers look for people who fit a certain description, called eligibility criteria: person's general health condition or prior treatments.
