Stopping or reducing tocilizumab for well-controlled giant cell arteritis
This study compares stopping tocilizumab (Actemra) completely versus reducing the dose in people whose giant cell arteritis has been well controlled for at least a year. The goal is to find out which approach keeps the disease in remission while reducing medication side effects.

Compare two steroid taper schedules for giant cell arteritis
This Phase 3 study compares how two standard steroid dose-reduction (tapering) schedules work for people with giant cell arteritis. It aims to see which taper approach controls the disease while reducing problems from long-term steroid use.
CaenAges 50 years+ - NCT04102930Recruiting
Study of immune and genetic features in GCA and PMR
This study looks at immune system and genetic (inherited) differences in people diagnosed with giant cell arteritis or polymyalgia rheumatica. It aims to improve understanding of why these conditions happen and how they vary between people.
Canterbury, KentAges 50 years+ - NCT05479448Recruiting
Tracking what predicts response in new PMR or GCA
This study looks at people newly diagnosed with polymyalgia rheumatica (PMR) or giant cell arteritis (GCA) and uses their health and treatment information to learn what predicts how well treatment works. It may help your care in the future by improving which patients respond best and how.
BaselAges 18 years+ - NCT05749094Recruiting
Ultrasound of the optic nerve in new suspected giant eye artery disease
This trial studies whether a quick ultrasound of the optic nerve (plus an eye exam) can help evaluate new suspected giant cell arteritis (GCA). It may help doctors assess eye risk early and decide on the best next steps.
London, OntarioAges 50–99 - NCT05854927Recruiting
MRI test for suspected giant cell arteritis
This study checks whether different MRI scanning details can better help doctors diagnose giant cell arteritis. If you’re being sent for an injected MRI because GCA is suspected, your scan results may help improve how future diagnoses are made.
ParisAges 18 years+ - NCT05865054Recruiting
MRI check in early suspected giant cell arteritis
This trial tests how well a special MRI (picture scan) can evaluate giant cell arteritis when it’s newly suspected and symptoms started recently. It may help doctors confirm the diagnosis and decide on treatment sooner by comparing MRI findings with standard testing like biopsy or ultrasound.
Rochester, MinnesotaAges 50 years+ - NCT05904301Recruiting
Registry for autoimmune and autoinflammatory disease patients
This study builds a nationwide list (registry) of people with certain autoimmune or inflammation-related illnesses. It helps researchers understand these diseases better over time, which can guide future care.
YerevanAges Any age - NCT06004154Recruiting
Imaging follow-up for giant cell arteritis patients
This study follows up patients with giant cell arteritis (Horton's disease) using MRI and ultrasound to see how the disease and treatment affect blood vessels over time. It aims to improve understanding of the condition and your imaging results.
ParisAges 50 years+ - NCT06279065Recruiting
Gut bacteria and giant cell arteritis study
This trial looks at how the bacteria in your gut might affect giant cell arteritis, a condition that causes inflammation in blood vessels. It aims to help doctors better understand the disease.
Bonn, North Rhine-WestphaliaAges 18 years+ - NCT06460142Recruiting
Biomarker study for giant cell arteritis and polymyalgia rheumatica
This study is looking for biomarkers (biological clues) in people with newly diagnosed or flaring giant cell arteritis (GCA) or polymyalgia rheumatica (PMR). Participating may help researchers find better ways to diagnose and monitor these conditions.
Bonn, North Rhine-WestphaliaAges 18 years+ - NCT06500728Recruiting
Vision involvement in giant cell arteritis
This study looks at how vision is affected in people with giant cell arteritis (GCA) -- a condition where blood vessels become inflamed. It compares those with GCA-related vision loss to people who have similar vision problems but not from GCA, to better understand and treat these eye issues.
Milan, LombardyAges 18 years+ - NCT06609668Recruiting
Thrombomodulin blood test to rule out giant cell arteritis in PMR
This study tests whether a blood test for a protein called thrombomodulin can help rule out giant cell arteritis (a blood vessel inflammation) in people with polymyalgia rheumatica. It involves a blood draw and a one-time imaging scan to look at your blood vessels.
DijonAges 50 years+ - NCT06742671Recruiting
Fast-track pathway for giant cell arteritis diagnosis
This trial tests a fast-track process to quickly diagnose giant cell arteritis (GCA), a condition that causes blood vessel inflammation. It may help patients get the right care faster.
La RochelleAges 50 years+ - NCT06887062RecruitingPhase 2
Testing dapagliflozin and bosentan for large vessel vasculitis
This trial tests two drugs, dapagliflozin and bosentan, to see if they help people with large vessel vasculitis who have been in remission for at least 6 months. The goal is to prevent flares and improve blood vessel health.
EdinburghAges 18 years+ - NCT06894602Recruiting
Can Ultrasound Predict Relapse in Giant Cell Arteritis?
This study uses an ultrasound of the temporal artery (a vessel in your temple) to see if certain findings can predict whether giant cell arteritis will come back. It may help doctors know who needs closer monitoring.
BrestAges 18 years+ - NCT07001059Recruiting
Ultrasound to see nerve swelling in giant cell arteritis
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.
Aix-en-ProvenceAges 50 years+ - NCT07084480Recruiting
A study on giant cell arteritis for precision medicine
This trial looks at giant cell arteritis (GCA) and polymyalgia rheumatica (PMR) to find more personalized treatments. If you have been diagnosed with either condition, you may be able to help researchers understand these diseases better.
WürzburgAges 18 years+ - NCT07206238Recruiting
Orbital blood vessel inflammation in optic nerve disease
This study uses MRI scans to look at inflammation in blood vessels around the eye in two conditions: giant cell arteritis (GCA, a type of blood vessel inflammation) and ischemic optic neuropathy (a condition where the optic nerve doesn't get enough blood). The goal is to better understand how inflammation affects the optic nerve and vision, which could help guide future treatments.
Glostrup MunicipalityAges 50 years+ - NCT07246577Recruiting
Improving diagnosis and monitoring in giant cell arteritis
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.
GothenburgAges 18 years+ - NCT07552636Recruiting
Monitoring Giant Cell Arteritis During Treatment Tapering
This study tracks patients with giant cell arteritis (GCA, a blood vessel inflammation affecting older adults) who are in remission and tapering their steroid medications. Researchers will monitor disease activity through blood tests and patient questionnaires to understand if their condition stays stable as they reduce treatment.

Common questions
- Are there clinical trials for giant cell arteritis?
- Yes. Clin2 currently lists 35 recruiting giant cell arteritis studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a giant cell arteritis trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a giant cell arteritis trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
