ANEURYSMAL SUBARACHNOID HEMORRHAGE

This study is tracking how well a device called NeVa VS works to open narrowed brain arteries in people who had a bleeding aneurysm. The device is already approved for this use, and researchers want to see how it performs in routine care. About 200 adults will be followed to meas…

This study tests whether giving patients electrical muscle stimulation and high-protein shakes soon after a type of stroke (aneurysmal subarachnoid hemorrhage) can prevent muscle loss and improve recovery. Thirty adults will receive the combo therapy or standard care. The main go…

This study looks at a new way to treat severe brain bleeds caused by aneurysms. Instead of coiling the whole aneurysm, doctors will only coil the dome (the bulging part). The goal is to see if this lowers the risk of re-bleeding and improves recovery. The study will enroll 30 adu…

This study tests whether the drug deferiprone can safely lower iron levels in the brain after a bleeding aneurysm. About 66 adults who had a ruptured aneurysm will receive either deferiprone or a placebo for 14 days. Researchers will measure iron in spinal fluid, brain MRI scans,…

This study tests whether starting lumbar drainage and injecting the clot-busting drug urokinase early after a severe brain bleed improves patients' recovery. About 424 adults with a first-time severe aneurysmal subarachnoid hemorrhage will be randomly assigned to get either the a…

This study tests a drug called tocilizumab-aazg in 30 adults who have had a burst brain aneurysm. The goal is to see if the drug is safe and might help prevent strokes that can happen after the bleeding. Participants will receive the drug within 24 hours of the aneurysm rupture a…

This study tests whether a steroid pill called fludrocortisone can reduce death and disability in people who have had a brain bleed from a burst aneurysm. The trial will enroll 524 critically ill adults who have had their aneurysm secured. Half will receive the drug, half a place…

This Phase 2 trial tests whether deferoxamine, a drug that binds excess iron, can reduce brain injury after aneurysmal subarachnoid hemorrhage (aSAH), a severe stroke with high death and disability rates. About 120 participants will receive one of two doses of deferoxamine or a p…

This phase 2 trial tests whether levosimendan, a heart medication that widens blood vessels, can reduce dangerous artery spasms and delayed brain injury after a type of bleeding stroke called aneurysmal subarachnoid hemorrhage. Thirty adults in intensive care will receive either …

This study tests whether injecting the drug nicardipine into the spinal fluid can improve recovery in people who develop blood vessel spasms after a brain aneurysm bleed. About 396 adults aged 18–80 will receive either the drug or a sham procedure. The goal is to see if the treat…

This study is testing whether machine learning and special brain injury markers in blood and spinal fluid can warn doctors early when a patient with a brain bleed is developing delayed cerebral ischemia (lack of oxygen to the brain). Researchers will monitor 1,500 adults in inten…

This study tests whether a numbing nasal spray can safely reduce severe headaches after a brain aneurysm bleed. About 20 adults in the ICU will receive the spray along with standard pain meds. Researchers will compare pain levels and opioid use before and after treatment to see i…

This study looks at whether levels of nitric oxide in spinal fluid can predict dangerous blood vessel spasms after a type of brain bleed called subarachnoid hemorrhage. Researchers will compare nitric oxide levels in 40 patients with and without this condition. The goal is to fin…

This study is tracking 5,000 people who had a brain bleed from a ruptured aneurysm. Researchers are collecting medical data to find factors that predict complications like delayed brain injury or long-term disability. The goal is to create a computer model that helps doctors fore…

This study is looking at 160 people who had a ruptured brain aneurysm and need a temporary drain. Researchers will measure glucose in their spinal fluid and blood daily for up to 14 days. The goal is to see if higher glucose levels are linked to needing a permanent shunt later. P…

This study is collecting information from 1,000 people who have been treated for brain aneurysms or stroke using MicroVention devices. The goal is to see how well these treatments work in real life, not just in controlled trials. No new treatments are being tested—just data gathe…

This study enrolls 2,000 adults who had a brain bleed from a ruptured aneurysm. Researchers will collect blood, spinal fluid, urine, and stool samples to analyze genes, proteins, and other molecules. The goal is to understand why some patients develop serious complications like d…

This study follows 8,000 adults who have had a stroke to learn why some develop memory and thinking problems afterward. Researchers will track changes in cognition, brain scans, and blood samples over time. The goal is to help doctors identify who is at risk for dementia and pave…
