Brain ischemia

This phase 2b trial tests whether injecting allogeneic neural stem cells (CC-101) into the brain near a prior stroke lesion can improve motor function in adults with chronic ischemic stroke and lasting movement problems. About 36 participants will receive either stem cells plus s…

This study tests whether giving aspirin early after repairing a ruptured brain aneurysm helps patients recover better. About 388 adults who had a bleeding aneurysm will receive either aspirin or a placebo for 10–14 days. The goal is to see if aspirin reduces brain complications a…

This study tests whether giving a clot-busting drug called tenecteplase before a mechanical clot removal procedure helps people with large ischemic strokes recover better than the procedure alone. About 486 adults with large-vessel occlusion strokes will be randomly assigned to o…

This study tests whether cooling the head (using a special cap) during emergency stroke treatment can reduce the amount of brain tissue that dies. About 182 adults having a major stroke and undergoing a clot-removal procedure will be randomly assigned to receive either standard c…

This trial tests a new device called Supernova that removes blood clots from large brain arteries in people having a stroke. The goal is to restore blood flow within 24 hours of symptoms starting. The study will include 3,000 participants and measure how well the device works and…

Carotid endarterectomy removes plaque from the neck artery, and surgeons clamp the artery briefly during the operation. In awake patients, doctors check hand strength and speech to decide if a shunt is needed. This study tests whether a forehead sensor that measures brain oxygen …

This study will test a new radioactive tracer called FBFP in 30 stroke patients and 20 healthy volunteers. The tracer is used with a PET/MR scanner to take detailed pictures of the brain. The goal is to see if FBFP can help doctors diagnose and understand stroke better. Participa…

This trial tests whether ticagrelor, an antiplatelet drug, can prevent stroke and delayed brain ischemia in people who have had a low-grade aneurysmal subarachnoid hemorrhage. Participants receive either ticagrelor or a placebo for 14 days, starting just before endovascular treat…

This study tests whether a mild electrical current applied to the scalp (tDCS) can improve naming ability in people who have trouble speaking after a recent stroke. Twenty-eight adults with aphasia will receive either real or sham stimulation over five days. The goal is to see if…

This study looks at 300 adults with a brain bleed from a ruptured aneurysm. It tests a non-invasive headband to monitor brain blood flow and two nerve treatments (a neck injection and ear stimulation) to see if they improve brain function. The goal is to find better ways to preve…

This study will compare how quickly stroke-related brain damage worsens in 135 Afro-Caribbean patients in Guadeloupe versus patients from mainland France. Researchers will use brain scans to track blood flow and collateral circulation. The goal is to learn if stroke progression d…
