This study uses a laser-based imaging method to “see” inflammation in people with rheumatoid arthritis. It may help researchers better understand how active joint inflammation looks and how it changes.
Ann Arbor, MichiganAges 18 years+ - NCT03632239Enrolling by invitation
Share whole-genome or exome data for research
This trial is about building a large library of genetic test results (whole exome or whole genome sequencing) that researchers can use. You may be eligible if your sequencing data is available and you (or your study contact) can be reached again so researchers can include your information responsibly.
Bethesda, MarylandAges 4–120 - NCT03366168Recruiting
Using tongue tissue to grow stem cells in adults
This study takes a small sample from the front of your tongue to grow stem cells from your taste-bud tissue. It aims to understand whether this approach can be safely done in healthy adults and explore how the cells might be used in the future.
Baltimore, MarylandAges 18–120 - NCT03300830Recruiting
Testing tumors linked to viruses, HIV, and immune disorders
This study collects and analyzes tumor tissue to learn what drives certain cancers and growths linked to viruses, HIV, and immune system problems. Results may help researchers understand disease causes and point to better future treatments.
Bethesda, MarylandAges 18 years+ - NCT03307304Recruiting
Studying different forms of childhood brain-wasting disease
This study looks at people with CLN3 and other related forms of NCL (a childhood brain-wasting illness) to better describe symptoms and disease changes over time. You may be followed with regular check-ins, medical records, and sometimes NIH visits or sample collection.
Bethesda, MarylandAges 1 week–100 years - NCT03307317Recruiting
Testing brain signaling in infants at early risk
This study looks at how the brain “mirrors” or responds to actions, with the goal of finding early signs of neurodevelopmental disorders. It includes healthy adults and infants, and infants who may be at risk, to compare brain patterns early on.
Bethesda, MarylandAges 9 months–65 years - NCT03407066Recruiting
Study of how people see, hear, think, and move
This study measures how the brain processes sight and other senses through tests done in a lab, online, or by off-site/genetic screening. It may help researchers understand normal perception and cognition, which can guide future treatments.
