Impact of Chemokine Receptor 5 (CCR5) Inhibition on Sarcoidosis Immunophenotypes
GRADS

Brief Summary
The study hypothesizes that inhibition of the receptor CCR5 by maraviroc will diminish inflammation in patients with sarcoidosis. Subjects with active sarcoidosis will first undergo bronchoscopy with bronchoalveolar lavage to recover lung immune cells for baseline analysis. They will then receive the drug maraviroc for 6 weeks duration. They will then undergo a repeat bronchoscopy with bronchoalveolar lavage to recover lung immune cells for analysis following maraviroc treatment.

Study Arms (1)
sarcoidosis stage II
EXPERIMENTALAll subjects with active stage II sarcoidosis with or without skin disease will receive the drug maraviroc 300mg to be taken orally twice a day for 6 weeks duration.
Interventions
Bronchoscopy employs a flexible instrument that is inserted into the trachea and proximal airways after topical anesthesia. Bronchoalveolar lavage involves the instillation of saline solution through the bronchoscope into the airways followed by recovery under suction to collects lung fluid containing cells and proteins.
Venipunctures will be performed at study entry, after two weeks, and at the end of the study to collect blood for research studies and safety laboratories.
For subjects with sarcoidosis skin lesions, an optional skin biopsy specimen may be collected for research studies.
Eligibility Criteria
You may qualify if:
- Histologically proven sarcoidosis from any site (noncaseating granulomas without other causes).
- Diagnosis of active sarcoidosis (Sec. 5.5.4.t) clinical stage II by Chest X-ray (CXR).
- Forced Vital Capacity (FVC) \>45% and Diffusing Capacity for Carbon Monoxide (DLCO) \>50% of predicted values.
- Evidence of active sarcoidosis (see criteria above)
- Able and willing to complete all study procedures (e.g., bronchoscopy, post-drug surveillance)
- Age: 18+ years old (prevalence greatest in young adults; pediatric maraviroc safety not established).
- Not on immunosuppression for sarcoidosis at the time of recruitment, (e.g., steroids, tumor necrosis factor alpha (TNF-a) blockade)
- Liver function (transaminases, bilirubin), coagulation (International Normalized Ratio (INR), partial thromboplastin time (PTT), platelet count), blood urea nitrogen (BUN), creatinine, and white blood count (WBC) within normal limits.
- If female: negative pregnancy test, agreement to use reliable contraception if of childbearing potential 30 days prior and for 30 days after study completion (drug safety during pregnancy not established).
- Negative HIV and HBsAg tests
You may not qualify if:
- Diagnosis of infection based upon clinical evaluation and/or microbial testing.
- The diagnosis of any disease involving the heart, lungs, liver (HVC), kidney, hematologic, endocrine, or Gl systems which, in the judgment of the PI, would pose an undue risk to the subject if they participated in this study. This includes but is not limited to diabetes, uncontrolled hypertension, liver disease (HVC), or history of malignancy.
- Medications that will either inhibit or induce CYP3A4 (including St John's Wort)
