About this study

Sarcoidosis is a granulomatous disease for which the molecular and immunologic association with mycobacteria continues to strengthen. The investigators are interested in conducting a proof-of-concept investigation of the effects of antibiotics on sarcoidosis resolution. The investigators hypothesize that pulmonary sarcoidosis will improve faster if patients are given antimycobacterial therapy, in addition to their standard therapy.

Being tested
levaquin; ethambutol; rifampin and azithromycin.
Keywords
sarcoidosis, mycobacteria, lung, pulmonary, radiographic improvement
Medical subject headings
Sarcoidosis, Pulmonary, Sarcoidosis, Mycobacterium Infections

What participants receive

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

  • levaquin; ethambutol; rifampin and azithromycin.Drug

    Levaquin 750 mg loading on day 1, then 500 mg po QD Ethambutol 15-25 mg/kg for a maximum of 1200mg po QD Azithromycin 500mg on day 1, then 250 mg po QD

    Rifampin 10 mg/kg for a maximum of 600mg po QD or Rifabutin 10 mg/kg for a maximum of 300 mg po QD. We will not use both, but either one or the other based upon if the patient is on other medications that are metabolized by the cytochrome P450 pathway.

What is being measured

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

  1. Change in Absolute FVC From Baseline to Post Completion of 8 Weeks of Antibiotic Therapy.

    The primary endpoint was improvement in absolute FVC from baseline to completion of therapy. Spirometry testing was performed using a standardized calibrated laptop spirometer, Flowscreen II USA Spirometer (VIASYS Healthcare Inc., Yorba Linda, CA). The volume accuracy of the spirometer was checked daily using a three liter calibration syringe. Each subject was given at least three attempts and the greatest measurement for absolute FVC and Forced Expiratory Volume (FEV1) at baseline, four week, and eight week assessments was recorded.

    Measured: 8 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing levaquin; ethambutol; rifampin and azithromycin. in people with Pulmonary Sarcoidosis and Lung Function, run by Vanderbilt University 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 9 inclusion and 6 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 31 Oct 2012. 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. 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?

Yes. Results are posted in the registry (first posted 19 Oct 2012). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Change in Absolute FVC From Baseline to Post Completion of 8 Weeks of Antibiotic Therapy. (time frame: 8 weeks). 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 NCT01169038, 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 31 Oct 2012.
