Fast-track pathway for giant cell arteritis diagnosis

This trial is for people newly diagnosed with giant cell arteritis (GCA) who have a 'halo' sign on their temporal artery ultrasound. It will study how quickly the halo disappears after starting steroid treatment, helping doctors understand the best way to use steroids for this condition.

This study uses ultrasound, a biopsy of the temple artery, and blood tests to improve how giant cell arteritis (GCA) is diagnosed, monitored, and predicted. It may help doctors find better ways to manage this condition.

This trial tests whether the drug upadacitinib can help people with giant cell arteritis (GCA) that affects the large blood vessels, such as the aorta. It is for those who have not responded to, cannot tolerate, or cannot use another treatment called tocilizumab.

This trial tests if a shorter course of the steroid prednisone, combined with tocilizumab, works as well as a longer course for giant cell arteritis. You must already be starting tocilizumab and taking at least 20 mg of prednisone daily.

This study tests whether bosentan, a medicine usually used for blood pressure in the lungs, can help control inflammation and symptoms in patients with giant cell arteritis (GCA). The goal is to see if it can reduce the need for steroids and improve quality of life.

This trial uses an ultrasound to check for swelling around the optic nerve in people who may have giant cell arteritis (GCA). It aims to see if this test can help diagnose GCA faster.
