About this study

Official title: Noninvasive Quantification of the Pulmonary Anti-inflammatory Effect of Rosiglitazone

The purpose of this research study is to gain understanding of the basic responses of the lung to inflammation and specifically if a certain medication can reduce the inflammation alone or in combination with another. Inflammation is the way our bodies react to irritation or injury, and involves red, warm, and often painful swelling of the affected tissue. "Acute lung injury" involves inflammation that is not specific to one area of the lung and is caused by any one of several conditions: infection, trauma, breathing toxic substances, etc. When lung injury is severe, not enough oxygen can get into the body; this can lead to the need for mechanical support of breathing (mechanical ventilation), problems with brain, heart or other organ function, and in some cases, death.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • ZileutonDrug

    Also called Zyflo

    600 mg tablets po QID for 5 days prior to endotoxin, stopping 24 hours after endotoxin instillation

  • Pioglitazone placeboDrug

    Lactose filled gelatin capsule, size 00, 1 tablet po bid x 2 weeks prior to endotoxin instillation until 24 hours after endotoxin.

  • Zileuton placeboDrug

    Placebo tablets provided by manufacturer of Zyflo CR (Cornerstone Therapeutics), 2 tablets po bid x 5 days prior to endotoxin instillation until 24 hours after endotoxin.

  • PioglitazoneDrug

    Also called Actos

    PPAR-gamma agonist

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Ki, measure of FDG uptake

    Ki will be measured before and after endotoxin. Primary outcome measure is change in Ki (post- minus pre-endotoxin value) and absolute Ki after endotoxin.

    Measured: Before and after endotoxin

Secondary outcomes (1)
  1. Bronchoalveolar lavage (BAL) fluid cell counts

    Total and neutrophil cell counts obtained by bronchoalveolar lavage after endotoxin.

    Measured: After endotoxin

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Zileuton and Pioglitazone in people with Lung Inflammation, run by Washington University School of Medicine at 1 site 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 7 inclusion and 15 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 23 Apr 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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. Some participants in this study may receive a placebo. 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?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

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.

What does the primary outcome measure?

Ki, measure of FDG uptake (time frame: Before and after endotoxin). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT01174056, 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 23 Apr 2014.
