Impact of Chemokine Receptor 5 (CCR5) Inhibition on Sarcoidosis Immunophenotypes
Stopped: Poor recruitment
United States3 participantsStarted 2014-01
Plain-language 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.

Inclusion criteria
✓. 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.

What they're measuring
1
Total Cell Count and Differentials in Blood and Bronchoalveolar Lavage Fluid Pre- and Post Maraviroc
✕. 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)
