Intracranial atherosclerosis

This trial compares two rescue procedures for people who have a stroke caused by a hardened, narrowed brain artery that still has significant blockage after initial endovascular treatment. About 486 participants will be randomly assigned to receive either balloon angioplasty or s…

This study tests whether adding a PCSK9 inhibitor (Recaticimab) to standard statin therapy can reverse plaque buildup in brain arteries of people with asymptomatic intracranial atherosclerosis. About 300 participants will receive either the drug combo or statins alone for 24 week…

This study tests a new stent (a small mesh tube) placed in brain arteries to prevent strokes in people whose arteries are narrowed by plaque. It includes 200 adults aged 18-75 who have had a stroke or mini-stroke despite medication. The main goal is to see if the stent is safe an…

This study tests whether dulaglutide, a once-weekly diabetes injection, can improve blood flow in the brains of people with severely narrowed arteries. About 130 participants who recently had a mini-stroke or mild stroke will receive either standard care or dulaglutide plus stand…

This study compares two treatments for stroke patients whose brain arteries remain blocked after initial clot removal, due to underlying hardening of the arteries (atherosclerosis). About 498 participants will be randomly assigned to receive either urgent stenting or continued st…

This study looks at whether a genetic test can help doctors pick the right blood thinner for people who have had a stroke due to narrowed arteries in the brain. Some people's genes make the common drug clopidogrel less effective, so another drug, ticagrelor, may work better. The …

Researchers are building a large database of high-resolution MRI scans from stroke patients in China to study the fatty plaques inside brain arteries. The study enrolls adults who recently had an ischemic stroke and have a specific plaque in a major brain artery. By tracking thes…

This study follows 100 people with severe narrowing of brain arteries to understand why some develop memory and thinking problems. Participants receive either standard medications or a procedure to open the artery. Researchers will track changes in memory and stroke risk over tim…
