About this study

Official title: An Interventional Study of the Effect of CCR5 Inhibition With Maraviroc on Immune Cells in the the Lung and in Peripheral Blood of Patients With Sarcoidosis

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.

Read the detailed description

The investigators hypothesize that inhibition of CCR5 by maraviroc may have a beneficial immunomodulatory effect on the granulomatous inflammation of pulmonary sarcoidosis. The specific aim of this proposal is the investigate the effect of CCR5 inhibition on the trafficking of mononuclear cells to the lung, skin, peripheral blood in subjects with active sarcoidosis exposed to the CCR5 inhibitor, maraviroc. A second aim will be to isolate by cell sorting cluster of differentiation 4 (CD4)+CCR5+ T cells for amplified gene expression profiling before and after CCR5 inhibition, experiments the investigators believe will elucidate genes associated with downstream activation and inhibition of CCR5 receptor function.

What participants receive

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

  • all subjects will receive maraviroc 300mg orally twice a day for 6 weeksDrug

    Also called maraviroc, selzentry

  • Bronchoscopy with bronchoalveolar lavageProcedure or surgery

    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.

  • venipuncturesProcedure or surgery

    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.

  • Skin biopsyProcedure or surgery

    For subjects with sarcoidosis skin lesions, an optional skin biopsy specimen may be collected for research studies.

    General indicators of inflammation following chemokine receptor 5 (CCR5) inhibition in blood and bronchoalveolar lavage

    Measured: 6 weeks

Secondary outcomes (2)
  1. Mononuclear Cell (MNC) Activation and T-cell Differentiation

    Measured: 6 weeks

  2. Chemokine Receptor 5 (CCR5) Expression Among These Immune Effector Cells

    CCR5 expression among these immune effector cells before and after CCR5 inhibition.

    Measured: 6 weeks

Questions about this trial

What is this clinical trial studying?

A study testing all subjects will receive maraviroc 300mg orally twice a day for 6 weeks, Bronchoscopy with bronchoalveolar lavage and venipunctures in people with Sarcoidosis, run by Kevin F. Gibson at 1 site 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 10 inclusion and 3 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: stopped early, as of the sponsor's last update on 3 Dec 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site 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. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Yes. Results are posted in the registry (first posted 18 Jul 2017). 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?

Total Cell Count and Differentials in Blood and Bronchoalveolar Lavage Fluid Pre- and Post Maraviroc (time frame: 6 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 3 Dec 2025.
