  • Indomethacin.
  • Ranitidine.
  • Probenecid.
  • Other experimental medications.
  • Patients will be excluded from the study for the following reasons:
  • Removal from zidovudine (AZT) during treatment on ACTG protocol 002 for recurrent grade 4 toxicity.
  • Removal from prior dideoxycytidine (ddC) therapy for peripheral neuropathy = or > grade 3.
  • Visceral or extensive Kaposi's sarcoma requiring therapy or another malignancy requiring therapy.

About this study

To evaluate the efficacy of AZT versus ddC in terms of survival, antiviral effects, neurological status, and health status in patients post Pneumocystis carinii pneumonia (PCP) who received long-term AZT therapy in ACTG protocol 002 While treatment with AZT has been found to be effective in prolonging survival and reducing the numbers of opportunistic infections in patients with AIDS, during the second year of administration of AZT an acceleration in mortality has been observed. The reasons for this are not known at this time. The study of what may be an AZT-resistant strain of HIV may benefit patients who have been and are still receiving AZT or another drug used in treating HIV ddC. It is hoped that the comparison of the effectiveness of AZT and ddC will benefit in the treatment of these patients.

While treatment with AZT has been found to be effective in prolonging survival and reducing the numbers of opportunistic infections in patients with AIDS, during the second year of administration of AZT an acceleration in mortality has been observed. The reasons for this are not known at this time. The study of what may be an AZT-resistant strain of HIV may benefit patients who have been and are still receiving AZT or another drug used in treating HIV ddC. It is hoped that the comparison of the effectiveness of AZT and ddC will benefit in the treatment of these patients.

Following tests to evaluate their health, patients are chosen at random to receive either AZT or ddC. AZT is given by mouth at the patients' current dose. ddC is given by mouth every 8 hours. Treatment continues for up to 12 months. Patients are required to visit the clinic every 2 weeks up to week 12 and then once a month. Blood samples are taken to monitor the safety and effectiveness of treatment.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Zidovudine and Zalcitabine in people with HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 5 sites in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 12 inclusion and 19 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Nov 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 5 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00000682, which also lists 2 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Nov 2021.
