About this study

Official title: A Randomized, Open-Label Trial of High Dose Atovaquone Versus Low Dose Atovaquone Versus Aerosolized Pentamidine for Prophylaxis of Pneumocystis Carinii Pneumonia in Patients With HIV Infection Who Are Intolerant of TMP/SMX

To assess whether high dose or low dose atovaquone suspension is more effective than aerosolized pentamidine as prophylaxis against Pneumocystis carinii pneumonia (PCP) in high-risk HIV-infected patients. To compare the safety of chronic administration of the three regimens in patients with advanced HIV disease. To determine the relationship between steady state atovaquone plasma concentrations and prophylactic efficacy against PCP.

Read the detailed description

Patients are randomized to receive oral atovaquone at 1 of 2 doses once daily or aerosolized pentamidine once every 4 weeks. Treatment continues until 18 months after the last patient is enrolled. Patients are stratified into primary or secondary prophylaxis strata based on prior occurrence of a PCP episode.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Atovaquone and Pentamidine isethionate in people with Pneumonia, Pneumocystis Carinii and HIV Infections, run by Glaxo Wellcome 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 14 inclusion and 16 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 24 Jun 2005. 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 NCT00002340, which also lists 1 linked publication.

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 24 Jun 2005.
