Active clinical trials for "Cerebral Infarction"

This study will examine the feasibility and effect of a program that combines exercise and feedback from a wearable device on upper limb movement practice and function in individuals with stroke.

A prospective, multicenter, randomized controlled, non-inferiority study to investigate the effectiveness and safety of SINOMED SR for endovascular treatment of acute ischemic stroke

This study is a multicentre, randomized, double-blind, placebo parallel controlled, investigator-sponsored study that aims to investigate the efficacy and safety of Edaravone Dexborneol treatment in patients with acute ischemic stroke who had received early reperfusion therapy.

Aneurysmal subarachnoid haemorrhage (aSAH) is a rare but severe subtype of stroke with high mortality and morbidity. Besides rebleeding, delayed cerebral ischaemia and cerebral vasospasm (CVS) are thought to be major reasons for the poor outcome in survivors of aSAH. Despite advances in the detection and treatment of CVS 20-40% of CVS patients experience cerebral Ischaemia. Experimental animal studies for ischaemic stroke, traumatic brain injury, and SAH showed that inhaled nitric oxide (iNO) selectively dilates cerebral arteries and arterioles in hypoperfused brain tissue. The investigators therefore performed this prospective pilot study to evaluate the effects of iNO on cerebral perfusion in patients with refractory vasospasm after aSAH.

Chronic cerebral ischemia (CCI) is viewed as an alarming state induced by long-term reduction in cerebral perfusion, which is associated with neurological deficits and high risk of stroke occurrence or recurrence. CCI accounts for a large proportion in both outpatient and inpatient subjects with cerebrovascular disease, while the treatment of CCI remains a formidable challenge to clinicians. Normobaric oxygen (NBO) is an adjuvant hyper-oxygenation intervention supplied with one atmosphere pressure (1ATA=101.325kPa). A plethora of studies have demonstrated the efficacy of NBO on the penumbra in acute stroke. NBO has been shown to increase oxygen pressure, raise intracranial blood flow, protect blood-brain barrier and enhance neuro-protective effects. As the similar underlying mechanisms shared by the penumbra in stroke and the ischemic-hypoxic brain tissues in CCI, the investigators speculate that NBO may serve as a promising therapeutic strategy for attenuating short-term symptoms or improving long-term clinical outcomes amongst patients with CCI. Due to the scant research exploring the efficacy of NBO for treating CCI so far, the clinical studies are warranted to verify this hypothesis urgently.

Currently, the guideline recommended re-perfusion such as intravenous thrombolysis and mechanical thrombectomy as the most effective treatment for acute ischemic stroke. However, the two methods are restricted by a strict time window, which greatly limits the number of the patients receiving treatment. The abundant studies have suggested that good collateral circulation can provide compensatory blood supply to save the ischemic penumbra and reduces the infarct volume, which improves the prognosis. How to improve collateral circulation in an efficient and safe way is a clinical challenge. Our recent experiment results of the animal and preliminary clinical experiments show that head-down position may significantly increase cerebral perfusion and improve neurological function. Clinically, head-down position is simple and easy to operate, and theoretically may increases brain perfusion and improve collateral circulation. A pilot randomized clinical trial is designed to investigate the effect of head-down position combined with routine rehabilitation in patients with ischemic stroke.The study is designed to explore the efficacy and safety of head-down position in patients with acute ischemic stroke

To assess safety of single IV (bolus + infusion) doses of ACT017 in patients with an acute ischemic stroke in addition to best emergency standard of care (including fibrinolysis by rtPA with or without added thrombectomy), with a specific focus on hemorrhage, whether clinically symptomatic (NIHSS score + 4 points or death, without other explanation), or seen (excluding other diagnoses) on 24-hour (hr) CT scan, serious adverse events (SAEs), suspected unexpected serious adverse reactions (SUSARs), and medically important events and other safety items including biological and immunological tolerability.

This is a randomized,controlled, double-blinded, phase 3 clinical study to evaluate the efficacy and safety of recombinant human urokinase(rhPro-UK) versus basic treatment for patients with acute ischaemic stroke in 4.5-6 hours after stroke onset.

The primary objective of the study is to determine whether one 300 mg dose of intravenous (IV) natalizumab reduces change in infarct volume from Baseline to Day 5 on magnetic resonance imaging (MRI) in participants with acute ischemic stroke when given at ≤6 hours or at >6 to ≤9 hours from when they were last known normal (LKN). The secondary objectives of this study in this study population are as follows: to assess the efficacy of natalizumab on change in infarct volume from Baseline to Day 30; to assess efficacy of natalizumab on change in infarct volume from 24 hours to Day 5 and Day 30; to assess the efficacy of natalizumab on clinical measures of stroke outcome; to assess the safety of natalizumab in participants with acute ischemic stroke.
