About this study

Official title: Investigation of the Efficacy of Antimycobacterial Therapy on Pulmonary Sarcoidosis Phase II Randomized, Double-blind, Placebo-controlled Trial

The primary purpose of this study is to investigate the efficacy and safety of oral antimycobacterial therapy in patients with confirmed progressive pulmonary sarcoidosis. We suspect that the CLEAR regimen will improve the absolute FVC percent predicted in chronic pulmonary sarcoidosis participants.

Read the detailed description

Primary Objective: To assess the efficacy and safety of oral CLEAR therapy in patients with confirmed progressive pulmonary sarcoidosis.

Hypothesis: The CLEAR regimen will improve the absolute FVC percent predicted in chronic pulmonary sarcoidosis participants by augmenting T cell responses through the normalization of p56Lck expression and IL-2 production.

Being tested
Levofloxacin, Ethambutol, Azithromycin, Rifampin, Placebo
Medical subject headings
Sarcoidosis

What participants receive

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

What is being measured

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

  1. Change in Percent Predicted Absolute Forced Vital Capacity (FVC) in Participants With Pulmonary Sarcoidosis, Comparing Baseline With Performance After Completion of 16 Weeks of Therapy.

    Change in percent predicted absolute forced vital capacity (FVC) in participants with pulmonary sarcoidosis, comparing baseline with performance after completion of 16 weeks of therapy. This will involve comparing sarcoidosis and placebo after 16 weeks of therapy.

    Measured: Baseline to 16 weeks

Secondary outcomes (11)
  1. Radiographic Improvement in Sarcoidosis Lung Disease by Frontal Chest X-ray .

    Radiographic improvement in sarcoidosis lung disease by frontal chest x-ray . Local investigators will score chest x-rays.

    Measured: Baseline and 16 weeks

  2. Six Minute Walk, Distance in Meters

    The 6-min walk test (6 MWT) is a submaximal exercise test that entails measurement of distance walked over a span of 6 minutes.

    Measured: Baseline, 4, 8, and 16 and 24 weeks

  3. Change in Oxygen Saturation

    measured using pulse oximetry

    Measured: Baseline, 4, 8, and 16 and 24 weeks

  4. Change in Level of Dyspnea

    Outcome measure if a composite

    Measured: Baseline, 4, 8 and 16 weeks

  5. Change in the Saint George's Respiratory Questionnaire (SGRQ)

    The SGRQ is a 50-item questionnaire developed to measure health status (quality of life) in patients with diseases of airways obstruction.

    Scores range from 0 to 100, with higher scores indicating more limitations.

    A minimum change in score of 4 units was established as clinically relevant after patient and clinician testing.

    Measured: Baseline and 16 weeks

  6. Fatigue Assessment Scale (FAS).

    The FAS is a 10-item general fatigue questionnaire to assess fatigue. Total scores can range from 10, indicating the lowest level of fatigue, to 50, denoting the highest.

    Measured: Baseline, 4, 8, 16 and 24 weeks

  7. Change in the King's Sarcoidosis Questionnaire (KSQ) for the Assessment of Health Status;

    The KSQ is a free, online questionnaire to be filled out by sarcoidosis patients. The questionnaire takes around 10 minutes and is split into 5 sections; general health status, lungs, medication, skin and eyes. There are 29 questions in total, however some questions may not be answered (depending on the type of sarcoidosis affected). Each question asks patients to rate how they feel about many different aspects of their life, for instance how much pain they are in or how difficult they find everyday tasks. Information provided is confidential. Results are given as a number between 1-100 with higher numbers indicating better health.

    Measured: Baseline and 16 weeks

  8. Adverse Events

    Safety profile of regimen as evidenced by the number of adverse events

    Measured: 24 weeks

  9. FEV1%

    FEV1% was measure pre and post 6 minute walk test

    Measured: Baseline, 4, 8, and 16 and 24 weeks

  10. Failure of Standard Therapy

    We will assess how many subjects in either arm need escalation of their standard regimen (ie increase in prednisone) during the 16 weeks.

    Measured: Baseline to 16 weeks

  11. Abnormal Lab Values

    Safety profile of regimen as evidenced by the number of abnormal lab values classified as Adverse Events

    Measured: baseline to 16 weeks

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Levofloxacin, Ethambutol and Azithromycin in people with Sarcoidosis; Antimycobacterial Therapy, run by Vanderbilt University at 6 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 4 inclusion and 24 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 9 Jul 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 6 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. 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?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

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 9 Jul 2020). 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 Percent Predicted Absolute Forced Vital Capacity (FVC) in Participants With Pulmonary Sarcoidosis, Comparing Baseline With Performance After Completion of 16 Weeks of Therapy. (time frame: Baseline to 16 weeks). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 9 Jul 2020.
