Imaging of Lymphatic Vessels in People With Rheumatoid Arthritis (RA) (NCT05197530)

🟢 Recruiting Phase1 💊 Investigational Drug / Biologic Sponsor: University of Rochester

🩺 Plain-English Summary (8th-Grade Level)

Lymphatic transport was previously examined by these investigators using Near InfraRed Indocyanine Green fluorescence imaging (NIR-ICG) of the upper extremities. They established reliable and reproducible methodologies in RA patients. The purpose of this phase 2 pilot is to study RA disease progression and effectiveness as well as the mechanism of action of clinical interventions using established NIR-ICG methodologies in previous studies.

Who can join: To join this study, participants generally need to meet the listed inclusion criteria (13 items) and avoid the listed exclusions (5 items).
