Brain infarction

This trial tests whether the Adacolumn device, which filters certain white blood cells from the blood, can reduce brain swelling in people who have had a severe stroke. Ten patients will receive the treatment within 24 hours of their stroke. The goal is to see if it prevents wors…

This phase 3 trial is testing whether giving a clot-busting drug before mechanical thrombectomy (a procedure to physically remove a blood clot) improves outcomes for people with severe strokes caused by large vessel occlusion. Participants are randomly assigned to receive tenecte…

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 giving a large amount of IV saline (about 2-2.5 liters) right after clot-busting treatment helps people recover from a stroke better than giving only a small amount. The trial will enroll 752 adults aged 18-80 who had an ischemic stroke and received throm…

This early study tests whether a drug called RK-4 can be safely injected through the skull into the brain of people having a severe stroke. Only 6 participants will receive the injection once a day for 3 days, using a special device. The main goal is to see if the procedure is fe…

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…

This study tests whether a procedure to remove blood clots from the brain can help people who have had a severe stroke. The trial will include 308 adults aged 18 to 80 with a large area of brain damage. Doctors will use special tools to clear the blocked artery and then check how…

This early-phase study tests a new drug called RK-4 for people with a severe type of stroke (large hemispheric infarction) who cannot have standard clot-removal treatment. The drug is injected directly into the skull bone marrow once daily for three days. The main goals are to ch…

This study tests a new drug called RK-4, injected directly into the skull bone marrow, for people with a severe type of stroke (large hemispheric infarction) who cannot have standard blood vessel treatments. About 194 participants will either get the RK-4 injection daily for 3 da…

This study will follow up to 12,750 stroke patients in Germany to learn how care is given from the moment symptoms start through hospital treatment, rehab, and long-term recovery. It includes both adults and children with ischemic stroke or brain bleeding. The goal is to collect …

This study will follow 30 adults who have had a stroke and have arm weakness. Researchers will use functional MRI scans at several time points over six months to see how the brain reorganizes itself. The goal is to link different patterns of brain activity to different levels of …
