GIANT CELL ARTERITIS

This study tests whether the drug abatacept can help people with giant cell arteritis, a condition that causes inflammation in blood vessels. About 78 adults with newly diagnosed or relapsing disease will receive either abatacept or a placebo for up to 12 months. The goal is to s…

This study is testing whether a special MRI scan can detect inflammation in the arteries that supply blood to the head, brain, and eyes. Researchers will enroll 400 people aged 50 and older with suspected giant cell arteritis, a condition that can cause headaches, vision loss, an…

This study looks at whether lower-resolution MRI scans can still reliably detect giant cell arteritis, a serious inflammation of arteries that can cause blindness or stroke. Researchers will compare different MRI techniques in 133 adults suspected of having the disease. If lower-…

This study tests a new type of PET/CT scan (AzaFol) to see if it can better diagnose giant cell arteritis, a condition that causes inflamed blood vessels. About 70 people with suspected GCA will get the new scan and a standard scan to compare accuracy. The goal is to improve diag…

This study looks at whether taking extra hydrocortisone during times of mild to moderate stress (physical or mental) can improve health-related quality of life, especially fatigue, in people with polymyalgia rheumatica (PMR) or giant cell arteritis (GCA) who are on long-term, low…

This study tracks the pregnancy experiences of women with vasculitis, a group of rare diseases causing blood vessel inflammation. Researchers will use online surveys to understand how vasculitis affects pregnancy and what outcomes occur. The goal is to gather information to help …

This study is building a large registry and biorepository of 5,000 adults with various rheumatic diseases like rheumatoid arthritis, lupus, and scleroderma. Researchers at Yale University will collect medical data and biological samples over time to better understand these condit…

This study looks at whether ultrasound scans of the temporal and axillary arteries can help predict relapses in people with giant cell arteritis, a disease that causes inflamed blood vessels. Researchers will follow 100 patients to see if certain ultrasound findings are linked to…

This study collects tissue samples from 1,000 people with various forms of vasculitis (blood vessel inflammation). Researchers will analyze these samples alongside clinical data to identify genes that increase disease risk. The goal is to better understand what causes these rare …

This study follows 400 adults diagnosed with giant cell arteritis or polymyalgia rheumatica to track serious side effects over time. Researchers will monitor for new or worsening aortic aneurysms and aortic dissections, as well as steroid-related complications. The goal is to bet…

This study collects DNA samples and medical information from 1,000 people with various forms of vasculitis (blood vessel inflammation). Researchers will analyze the data to identify genes that increase the risk of developing these severe diseases. The goal is to better understand…

This study follows up to 4,000 people with vasculitis (a group of diseases that cause blood vessel inflammation) and healthy volunteers over many years. Researchers collect blood, urine, imaging, and genetic samples to learn how the disease develops and changes. The goal is to fi…
