Active clinical trials for "Brain Infarction"

This is a prospective, open, single-arm, the real world of clinical trials. The researchers plan to recruit 300 eligible patients. The main purpose of this study is to evaluate the effectiveness and safety of butylphthalide in the treatment of ischemic stroke, and to establish a population pharmacokinetic model of butylphthalide in elderly patients to explore its blood drug concentration. Correlation with its efficacy and adverse reactions.

The CHOICE study suggested that the use of adjunct intra-arterial alteplase after successful endovascular reperfusion in large vessel occlusion acute ischemic strokes may result in a greater likelihood of excellent neurological outcome at 90 days. However, CHOICE was a phase-2 trial and almost exclusively enrolled anterior circulation occlusions. Therefore, data on the safety and efficacy of post-endovascular reperfusion IAT in posterior circulation stroke is lacking. In general, anterior circulation strokes are associated with a higher risk of ICH than posterior circulation strokes. Therefore, we believe it might be safer to perform post-endovascular reperfusion IAT posterior circulation stroke. Also, there are more perforator artery in the posterior circulation, IAT would be more likely to show its benefit. Therefore, we would like to explore IA rt-PA for posterior circulation stroke after successful MT in our RCT.

The purpose of this study is to compare the effectiveness of a 4-week lower extremity telerehabilitation protocol with aims to improve lower extremity function to a 4-week attention-controlled education program on lower extremity clinical outcomes, quality of life, and healthcare resources utilization among community dwelling adults with stroke across Canada.

This is a placebo controlled, randomized, double blinded study including Phase 1 and Phase 2. Phase I study is a safety assessment and Phase 2 study is incline to assess effectiveness of MSCs. Potential subjects must be screened and consented before enrolled. The primary objective of this study is to determine the effects of early intravenous infusion of allogeneic human umbilical cord mesenchymal stem cells (HucMSCs or MSCs used in the following section) for patients with acute ischemic stroke. Eligible patients will receive a single dose of MSCs or placebo within 24 hours after stroke. Patients will be followed for 2 years post infusion for safety and efficacy (change in neurological symptoms and quality of life). Assessments will occur during transplantation and at 3,7, 14 days and1,3, 6, 12, 18 and 24 months after infusions of stem cells.

This study aims to explore the safety and efficacy of 0.9% normal saline （NS） infusion on stroke after intravenous thrombolysis (IVT), we decided to conduct this multi-centre randomized controlled trial for the first time. This trial will provide an innovative strategy to facilitate functional independence after stroke administered with IVT. This is a multi-center, randomized controlled two arm (1:1 ratio) clinical trial. The enrolled participators will be divided into NS group and control group randomly after confirming as acute ischemic stroke (AIS) according to symptoms and signs. In NS group, the patient will undergo NS 2000ml intravenous infusion swiftly after IVT, with the speed of 200ml/h. In control group, the patient will not undergo NS intravenous infusion after IVT. The primary efficacy is disability at days 90, as scored by means of the modified Rankin scale (mRS), dichotomized as a favorable outcome (a score of 0 or 1), or an unfavorable outcome (a score of 2 to 6). The secondary outcomes mainly comprise neurological deficits, disability, imaging and laboratory tests at each follow-up time. The safety outcomes include the cerebral edema at 24-hour post-IVT detected by cranial CT, the 24-hour fluctuation of blood pressure and the cardiac function detected by ultrasonic cardiogram within 3 days after IVT. Stata 15.1 and R software will be used for statistical analysis

The aim of this study is to assess the effect of implementing best practices into current stroke rehabilitation physical therapy on walking outcomes. Participants will also be provided an activity monitor to help them track and target their walking practice to determine if this can improve walking ability.

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).

Silent brain infarctions (SBIs) are a manifestation of covert cerebrovascular disease, without obvious clinical deficit, noted very often in patients presenting with a new stroke or new transient ischemic attack. SBIs are linked to a significant increase in risk for subsequent stroke and cognitive decline. However, no biomarker is currently available that can predict the recurrence of these subclinical lesions. Coated-platelets are a measure of platelet procoagulant potential significantly increased in patients with ischemic stroke or transient ischemic attack compared to unaffected controls. Higher coated-platelet levels are strongly associated with both the presence and number of SBIs. Among medications approved for preventing stroke recurrence, we identified clopidogrel as a pharmacological agent leading to a decrease in coated-platelet levels. In this project, we plan to evaluate if clopidogrel can decrease the rate of occurrence of new silent brain infarctions. The result will enhance the investigators understanding of the relationship between platelets and silent brain infarcts, leading to improved health care delivery and also potential targets for novel preventive pharmacological interventions.

The aim of this study is to evaluate the effect of early rehabilitation treatment by electroencephalographic neurofeedback on upper limb motor function after stroke. Researchers will compare : Interventional group: electroencephalographic neurofeedback + traditional reference rehabilitation programme Control group: SHAM electroencephalographic neurofeedback + traditional reference rehabilitation programme

Emergent reperfusion is the main goal for acute ischemic stroke therapy (AIS). Endovascular therapy (EVT) is recommended within 6 hrs of stroke onset, and up to 24 hrs following perfusion imaging criteria. Despite the major benefit associated with MT, more than 50% of the patients remain disabled at 3 months. Reperfusion rates after MT are critical to determine functional outcome. However, complete reperfusion is obtained in only 50 % of the patients, due to, at least in part, erratic emboli and/or no-reflow processes. The aim of this study is to evaluate the efficacy of glenzocimab in addition to EVT and compared to EVT plus placebo, whether or not associated with ntravenous thrombolysis (IVT), on functional outcome at day 90.
