About this study
To determine the maximum tolerated dose (MTD) of WR 6026 in HIV-infected patients. To determine whether any unexpected toxicities are caused by WR 6026 in HIV-infected patients. To determine whether there is additional toxicity when WR 6026 is given for 21 days rather than 14 days. To further investigate the pharmacokinetics and pharmacodynamics of WR 6026, and in particular to examine potential correlations between the area under the concentration-time curve and methemoglobinemia or other toxicities.
In recent animal studies, WR 6026 demonstrated inhibitory activity against Pneumocystis carinii pneumonia (PCP). This study will assess the safety and tolerance of this drug in HIV-infected patients who do not have PCP.

In recent animal studies, WR 6026 demonstrated inhibitory activity against Pneumocystis carinii pneumonia (PCP). This study will assess the safety and tolerance of this drug in HIV-infected patients who do not have PCP.
Escalating doses of WR 6026 will be studied in successive patient cohorts. Four patients will be randomized to active drug or placebo in a 3:1 ratio at each dose level until moderate toxicity is demonstrated. If one patient at a given dose level experiences WR 6026-related moderate or worse toxicity, the sample size for all subsequent dose levels will be doubled. If two or more patients at a given dose level experience moderate or dose-limiting toxicity, an additional four patients (randomized in the same 3:1 ratio) will be entered at that level, and sample size at all subsequent dose levels will be doubled. Dose escalation will continue until three of six patients receiving active drug at a given dose level experience dose-limiting or worse toxicity, or until two of six patients at a given dose level experience life-threatening toxicity. The MTD will be defined as the dose immediately below the highest dose studied. Eight additional patients will be studied at the presumed MTD to confirm tolerance.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Sitamaquine in people with Pneumonia, Pneumocystis Carinii and HIV Infections, run by National Institute of Allergy and Infectious Diseases (NIAID) at 2 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 11 inclusion and 12 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 4 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 2 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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 NCT00000740, 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 4 Nov 2021; AzTrials last refreshed its copy on 7 Nov 2026.
