Active clinical trials for "Cerebral Infarction"

Patients presenting to the emergency department with acute ischemic stroke, who are are eligible for standard intravenous thrombolytic therapy within 4.5 hours of stroke onset will be assessed for major vessel occlusion to determine their eligibility for the trial. All participants will receive intravenous tenecteplase and endovascular thrombectomy as standard care. The trial is a Bayesian Optimised Phase 2 dose-finding umbrella trial (single arm versus objective performance criterion of 20% substantial reperfusion prior to endovascular thrombectomy based on the EXTEND-IA TNK trials NCT02388061, NCT03340493). The aim is to determine the optimal dose of intravenous dornase alfa (recombinant human DNase 1) with sufficient promise to take forward in a seamless phase 2b/3 design.

Prospective, multi-center, single-arm early feasibility study enrolling a minimum of 15 subjects at up to a minimum of 3 active investigational sites in the United States. The subjects must be diagnosed with acute ischemic stroke (AIS), must be post-mechanical thrombectomy, will have had intravenous thrombolytics, and have a visible MCA, ACA or PCA occlusive clot on initial angiographic imaging. Each subject will receive the Pulse NanoMED procedure after attempted neurovascular therapy to achieve better reperfusion.

The trial is prospective, randomized, open-label, blinded endpoint (PROBE) design. Patients with acute ischemic stroke, who are eligible for standard intravenous thrombolysis within 4.5 hours of stroke onset will be randomized 1:1 to 0.25mg/kg or 0.9 mg/kg alteplase before all participants undergo endovascular thrombectomy.

This study is a multicentre, randomized, double-blind, placebo-controlled, investigator-sponsored study that aims to investigate the efficacy of colchicine in preventing recurrent stroke in the patients with acute minor-to-moderate ischemic stroke or TIA and a hsCRP level of ≥2mg/L.

This is a multi-intervention randomized controlled trial that aimed to develop a management pattern for stroke survivors. The program consists of monitoring the recovery process, early detecting the physical and mental disorders, suitably intervening for each patient to improve their quality of life. New intervention techniques will be firstly applied for post-stroke patients in Vietnam such as using the portable functional near-infrared spectroscopy (fNIRS) device to explore cortex frontal hemodynamic and motivational interviewing for psychological adjustment. A total of registered 92 stroke patients in Vietnam National Geriatrics Hospital will be included in the study for 6 months. Included patients will be randomized to an intervention group and received the long-term follow-up program or to a control group receiving standard care. The mental health and physical functioning of participants will be assessed at 0, 1, 3, and 6 months follow-up. This work was funded by Vingroup Joint Stock Company and supported by the Domestic Master/Ph.D. Scholarship Programme of Vingroup Innovation Foundation (VINIF), Vingroup Big Data Institute (VINBIGDATA).

Delayed cerebral ischemia (DCI) after aneurysmal subarachnoid hemorrhage (aSAH) was long thought to be caused by subarachnoid blood-induced vasospasm. Experimental and clinical evidence suggest activation of several pathophysiological pathways, affecting the cerebral microcirculation. Recently, lower in-hospital mortality and less non-home discharge was reported in patients treated with therapeutic low-molecular weight heparin (LMWH), compared to patients with standard, prophylactic LMWH, pointing towards a potential benefit of higher doses of LMWH in the acute course after aSAH. Treatment with therapeutic LMWH might improve clinical outcome in endovascularly treated aSAH patients. The primary objective is to evaluate whether aSAH patients treated with therapeutic LMWH have a lower 30-day mortality rate compared to patients treated with prophylactic LMWH. Secondary objectives are to evaluate whether there are significant differences between patients treated with therapeutic and prophylactic LMWH in development of DCI, (hemorrhagic) complications during admission, hydrocephalus, non-home discharge location, quality of life, clinical outcome and cognitive functioning at three and six months, total health care costs. A single center, prospective, phase II randomized clinical trial in aneurysmal SAH patients ≥18 years old, in whom the causative aneurysm is treated with endovascular coiling less than 72 hours after initial SAH. Patients are randomized into 2 groups: (1) Therapeutic dose LMWH group: the standard prophylactic dose, administered upon hospital admission, will be replaced by nadroparin s.c. twice daily 5700 IE anti-Xa, starting within 24 hours after coiling and continued until 21 days after ictus of initial SAH. After 21 days, patients will continue with standard care prophylactic dose until discharge or when mobilized for more than 6 hours per day; (2) Control group: standard of care treatment with prophylactic dose of LMWH; nadroparin, s.c. once daily 2850 AxaIU until discharge or when mobilized for at least 6 hours a day. Primary outcome: 30-days' mortality. Secondary outcome: DCI, venous thrombo-embolic complications, occurrence of major and non-major bleeding, hemorrhagic complications after external ventricular/lumbar drain (EVD/ELD) placement and lumbar puncture (LP), other SAH-related complications, shunt-dependent hydrocephalus, discharge location, quality of life, total health care costs, cognitive functioning, clinical outcome.

Vascular brain infarction (VBI) occurs in 67% of patients undergoing TEVAR. Overt stroke occurs in 13% of these patients and 88% of patients suffer from neurocognitive impairment. Cerebral air embolisation during the stent-graft deployment phase of TEVAR may be a cause of VBI. Standard treatment to de-air stent-grafts is through the use of a saline flush. This study aims to investigate whether carbon-dioxide or saline is the better fluid to de-air TEVAR stent-grafts prior to insertion in to the patient and compare VBI rate in the carbon-dioxide group and saline group.

The CARDIOSTROKE is a randomized trial comparing mobile-device assisted control of hypertension together with screening of occult atrial fibrillation to standard care in patients with recent ischemic stroke or transient ischemic attack.

A 6-month pilot randomized controlled trial designed to test the effect of the Mediterranean-DASH Intervention for Neurodegenerative Delay (MIND) Diet + usual medical care versus usual medical care on the rate of cognitive change and several other secondary outcomes through a randomized controlled trial in 60 mild stroke patients aged 35-70 years without dementia.

This is a prospective, multicenter, cohort study aiming to compare the safety and efficacy of EmboTrap II with other stent retrievers without inner channel for acute middle cerebral artery occlusion (MCAO). All enrolled patients will be followed up at 90 days after randomization.
