Intracranial arterial disease

This study tests a special balloon coated with medicine to open narrowed arteries in the brain and prevent strokes. About 264 people with severe artery narrowing will be treated and followed for 12 months. The goal is to see if the balloon is safe and keeps arteries open better t…

This study is a registry that will follow about 200 people with brain aneurysms who are treated with a flow diverter device (p64, p64 MW, or p48 MW). The goal is to see how safe and effective these devices are in real-world practice across France. Participants will be monitored f…

This study tests whether pemafibrate, a drug that lowers triglycerides, can prevent the worsening of narrowed brain arteries in people who have already had a stroke or mini-stroke. About 270 participants will be randomly assigned to receive either pemafibrate plus standard care o…

This trial tests whether low-dose colchicine, an anti-inflammatory drug typically used for gout, can reduce stroke risk and artery plaque in people with intracranial atherosclerotic disease (ICAD). ICAD is a leading cause of stroke in Asia, and even with standard treatment, the r…

This trial compares two strategies to prevent another stroke in people with severe narrowing of a major brain artery. One group receives a drug-eluting stent (a mesh tube that releases medication to keep the artery open) along with aggressive blood-thinning medication. The other …

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 looks at whether high-dose statins can reduce or stabilize fatty plaques in the brain's arteries that cause strokes. About 100 recent stroke patients will get intensive statin therapy and have their arteries scanned with a special MRI. The goal is to see if the plaques…

This study looks at 180 adults with moderate to severe narrowing of brain arteries who have high LDL cholesterol. Researchers want to see if improving cholesterol management can lower the chance of having a stroke. Participants will not receive any experimental treatment; instead…

This study is testing a special stent coated with the drug rapamycin to treat narrowed brain arteries in people who haven't gotten better with medication alone. About 300 participants will receive the stent and be monitored for up to a year to see if it reduces the risk of stroke…

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 a new drug-coated stent (NxiDIME) for people with severely narrowed brain arteries that have already caused a mini-stroke or stroke. The goal is to see if it keeps the artery open better than an existing stent. About 224 adults will be randomly assigned to get ei…

Brain arteriovenous malformations (bAVMs) are tangles of abnormal blood vessels that can rupture and cause bleeding in the brain. Researchers have found that these malformations often carry specific genetic mutations, but detecting them currently requires analyzing tissue removed…

This study tests whether an ultra-high-resolution CT scan, called photon-counting CT angiography, can accurately detect narrowing inside brain stents. The trial involves 200 adults who have had a stent placed in a brain artery and are due for a follow-up check. The new CT scan's …

This study is testing whether a special MRI technique, called 4D Flow MRI, can better detect and predict the growth of unruptured brain aneurysms. Researchers will follow adults with these aneurysms, using the advanced imaging to measure changes in the aneurysm's shape over time.…

This observational study is looking at 250 people who have had a stroke or mini-stroke due to narrowing of arteries in the brain. Researchers want to see if a specific platelet protein (FcγRIIa) and blood flow patterns on MRI can help predict who will have another stroke within a…

This study looks at fatty buildup in brain arteries that can break off and cause strokes. Researchers want to see if high-risk plaques look different from harmless ones. They will use special imaging to compare plaques in 140 people who have had a stroke with those who have not.

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…

This study is collecting information from up to 10,000 people who receive BALT medical devices for conditions like brain aneurysms, stroke, and blocked arteries. Researchers will track how well the devices work and if any safety issues arise during routine care. The goal is to ga…
