Biomarker Signature and Musculoskeletal Ultrasound Profile in Rheumatoid Arthritis Patients
Completed
- Conditions
- Rheumatoid Arthritis
- Registration Number
- NCT02476084
- Lead Sponsor
- University of Oxford
- Brief Summary
The purpose of this study is to determine the kinetics of change in quantitative measures of joint inflammation by state of the art power Doppler vascular imaging and to identify biomarkers in biological samples (synovial biopsies, DNA, RNA, PBMC, serum, plasma, urine and stool samples) from parallel cohorts of RA patients undergoing different treatments. This will be achieved implementing MSUS assessments, standard laboratories techniques (such as ELISAs, gene profiling, transcriptome analysis etc.) and the novel CyTOF™ technology.

- New York Heart Association (NYHA) grade 3 or 4 congestive cardiac failure.
- Demyelinating disease.
- Presence of a transplanted organ (with the exception of a corneal transplant > 3 months prior to screening).
