Epigenetic Regulation of Altered T-cell Immunity in Sarcoidosis
Study Purpose
Sarcoidosis is a multi-system granulomatous disorder that is triggered and influenced by gene-environment interactions. Although sarcoidosis predominantly affects the lungs in most cases, the clinical disease course is highly variable and any organ can be affected leading to end organ damage despite currently available therapeutics that unfortunately also have numerous and potentially devastating side effects. The environmental triggers of sarcoidosis are unknown but several occupational, environmental and infectious agents have been associated with sarcoidosis in susceptible hosts. Exposure to these triggers result in inflammation, characterized by activation of CD4+ T-cells, cytokine production, subsequent recruitment of other immune cells, and granuloma formation. Although several genetic markers have been associated with sarcoidosis, none fully explain individual susceptibility or clinical course variability, strongly implicating the environment and epigenetics. We have the ability to generate a map of the epigenetic histone modifications in immune cells via Chromatin Immuno-Precipitation coupled with next generation sequencing (ChIP-seq) and a map of transcriptome profiles via RNA-seq. The availability of histone and transcriptional signatures defining T cell activity in sarcoidosis will help identify the specific molecular programs affected by disease processes and can become the basis for future discovery of novel biomarker diagnostics in a clinical setting.

Accepts Healthy Volunteers
Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms |
No |

Study Type
An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes. An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes. Searching Both is inclusive of interventional and observational studies. |

Trial Details

Trial ID:
This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries. |
NCT03145922 |
|
Phase
Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans. Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data. Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs. Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use. |
