Exclusion Criteria:

  1. Inability to obtain consent
  2. Age less than 18 years
  3. Female participants of childbearing potential not willing to use one of the following methods of birth control for the duration of the study and 90 days after study completion: condoms, sponge, foams, jellies, diaphragm, non-hormonal intrauterine device, a vasectomized sole partner or abstinence. Note: Oral contraceptive pills are not effective birth control when taking rifamycin. A negative urine pregnancy test at screening visit if female of childbearing potential

  22. Any significant finding in the patient's medical history or physical or psychiatric exam prior to or after randomization that, in the opinion of the investigator, would affect patient safety or compliance or ability to deliver the study drug according to protocol.

Arms of the Study

Arm 1

Arm 2

Arm Type

Active Comparator

Placebo Comparator

Arm Label

Concomitant Levaquin, Ethambutol, Azithromycin and Rifampin

Placebo

Arm Description

Levofloxacin 500mg po QD; Ethambutol 1200mg po QD; Azithromycin 250 mg po QD; Rifampin 600mg po QD or Rifabutin 300mg po QD

Riboflavin will be used for rifampin; encapsulated microcrystalline cellulose will be used to replace the levofloxacin, ethambutol and azithromycin. The pill count will be the same as the comparator regimen.

Outcomes

Primary Outcome Measures

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.

Secondary Outcome Measures

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.
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.
Change in Oxygen Saturation
measured using pulse oximetry
Change in Level of Dyspnea
Outcome measure if a composite
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.
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.
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.
Adverse Events
Safety profile of regimen as evidenced by the number of adverse events
FEV1%
FEV1% was measure pre and post 6 minute walk test
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.
Abnormal Lab Values
Safety profile of regimen as evidenced by the number of abnormal lab values classified as Adverse Events

5. Study Description

Brief Summary
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.
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.
