About this trial

This is an interventional diagnostic trial for Sarcoidosis focused on measuring sarcoidosis, mycobacteria, cutaneous lesions

Eligibility Criteria

18 Years - undefined (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria:

  1. Patients with sarcoidosis as defined by the ATS/ERS/WASOG statement on sarcoidosis as defined by the clinical presentation consistent with sarcoidosis, biopsy finding granulomas, and no alternative for the cause of the granulomas, such as tuberculosis
  2. Patients must have chronic cutaneous skin lesions with or without taking chronic therapy (corticosteroids, methotrexate (max 10mg/week), azathioprine, hydroxychloroquine, cyclophosphamide, minocycline, doxycycline and chloroquine), in which the dose has not been altered in the 2 months prior to starting the study.
  3. Subject has a diagnosis of cutaneous sarcoidosis for greater than 6 months with a Sarcoidosis Activity and Severity Index assessment score of at least 4. Diagnosis can be made by either:

    • Skin lesions characteristic of sarcoidosis and a biopsy showing granulomas with no evidence of mycobacteria, fungus, or malignancy.
    • A biopsy that does not show granulomas, but the patient has characteristic skin lesions and history of clinical features suggesting sarcoidosis (previous biopsy revealing noncaseating granuloma, bilateral hilar adenopathy, erythema nodosum, uveitis, raised ACE level, BAL lymphocytosis (CD4:CD8>3.5), panda/lambda sign on gallium scan)
    • Accepted clinical variants include, but are not necessarily limited to the following:

      • lupus pernio

    • For purposes of this study "moderate to severe cutaneous sarcoidosis" is defined as the presence of sarcoidal skin lesions with any of the following features:

      • At least 5 easily visible facial lesions, or
      • Disease which involves > 3% BSA, or
      • Disease which confers functional impairment (e.g. nasal or visual field obstruction), or
      • Disease which confers significant symptoms of itching and/or pain.
  4. If female, subject is either not of childbearing potential, defined as postmenopausal for at least 1 year or surgically sterile (bilateral tubal ligation, bilateral oophorectomy, or hysterectomy), or is using 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, or intrauterine device
    • contraceptives (oral or parenteral) for three months prior to study drug administration
    • a vasectomized sole partner
    • Females of childbearing potential must have a negative serum pregnancy test at screening visit.

  13. Subject has a history of tuberculosis at anytime or close contact with a person with active tuberculosis within the previous 6 months, or persistent or active infections requiring hospitalization or treatment with IV antibiotics, IV antiretrovirals, or IV antifungals within 30 days of baseline, OR oral antibiotics, antivirals, or antifungals for purpose of treating infection, within 14 days of baseline.
  14. Evidence of other active skin diseases or skin infections during screening that may interfere with evaluation of sarcoidosis.
  15. Subject has an active infection requiring systemic antibiotics at time of screening
  16. Subject has a history of listeriosis, treated or untreated tuberculosis, exposure to individuals with tuberculosis.
  17. Subject has a variant of sarcoidosis that is not amenable to study evaluation, in the absence of chronic indurated lesions, such as:

    • Acute, "benign" sarcoid associated with erythema nodosum
    • Acute iritis
    • Ichthyosiform sarcoidosis
    • Hypo- or hyperpigmented macular sarcoidosis
    • Ulcerative sarcoidosis

Arms of the Study

Arm 2

Arm Type

Experimental

Placebo Comparator

Arm Label

Antibiotic Regimen

Placebo Regimen

Arm Description

The Antibiotic Regimen consists of Levaquin 750 mg loading on day 1, then 500 mg po QD and Ethambutol 15-25 mg/kg for a maximum of 1200mg QD and Azithromycin 500mg on day 1, then 250 mg po QD and Rifampin 5-10 mg/kg for a maximum of 300mg po QD. All four drugs are given concomitantly.

The placebo regimen consists of Lactose tablets, one for each antibiotic with equivalent pills

Outcomes

Primary Outcome Measures

Change in Lesion Size at the Completion of Antibiotic Therapy, Measured on a Continuous Scale; Change Will be Determined by Change in Diameter of the Lesions
Granuloma Burden
Number of patients with a decrease in Granuloma Burden (only in those patients having granulomas present at baseline biopsy)

Secondary Outcome Measures

Change in Modified Sarcoidosis Activity and Severity Index (SASI) at Completion of Therapy.
Characterization of lesion severity was conducted using Modified Sarcoidosis Activity and Severity Index (SASI), measuring erythema, induration and desquamation. The modification was that the same scale was applied to any part of the body, instead of the face alone. The scale range is 0 (no problem) to 72 (very severe).

5. Study Description

Brief Summary
Growing research from independent laboratories provide an association between mycobacteria and sarcoidosis. More recent immunologic and molecular studies demonstrate immune responses to mycobacteria virulence factors. The purpose of this study is to assess if administration of anti-mycobacterial drug therapy will aid in resolution of cutaneous sarcoidosis lesions.
Detailed Description
Independent molecular and immunologic investigations strengthen the association between mycobacterial antigens and sarcoidosis pathogenesis. Molecular analysis of sarcoidosis granulomas reveals the presence of Mycobacterium tuberculosis complex (MTB) DNA and proteins that are significantly absent from granulomatous controls. Mycobacterial DNA has been detected in cutaneous sarcoidosis lesions, in addition to systemic immune responses against mycobacterial antigens. Due to the association between sarcoidosis and mycobacterial antigens, we postulated that broad spectrum antimycobacterial therapy could lead to restoration of T cell function and clinical improvement of chronic cutaneous sarcoidosis lesions. We investigated the safety and efficacy of Concomitant Levofloxacin, Ethambutol, Azithromycin, and Rifampin (CLEAR) therapy among chronic cutaneous sarcoidosis subjects, with change in lesion diameter from baseline to completion of 8 weeks of therapy as the primary endpoint; we assessed for decreases in granuloma burden, if granulomas were evident upon histologic examination. Change in modified Sarcoidosis Activity Severity Index (SASI) was the secondary endpoint.
