Active clinical trials for "Cerebral Infarction"

This is a multicenter, doble blind, placebo controlled clinical trial to asses de safety and efficacy of intravenous administration of alogenic adipose tissue-derived mesenchymal stem cells in the first four days from acute ischemic stroke.

Acute ischemic stroke due to large vessel occlusion is responsible of cerebral blood flow impairment with a progressive and extensive ischemic process. Cerebral collateral circulation may preserve an ischemic penumbra that could recover providing timely reperfusion of the occluded vessel. Mechanical thrombectomy is the standard of care for anterior circulation large vessel reperfusion. Strategy to promote cerebral blood flow in collateral circulation before reperfusion is scarce and rely mainly on blood pressure maintenance. Carbon dioxide is a potent cerebral vasodilator that could enhance collateral circulation blood flow and cerebral protection before reperfusion. General anesthesia with endotracheal mechanical ventilation could be used for thrombectomy and give the opportunity to modulate and control carbon dioxide tension in the blood. This study will test the effect of moderate hypercapnia on penumbral collateral circulation before reperfusion during mechanical thrombectomy for anterior circulation acute ischemic stroke under general anesthesia.

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.

There is evidence that citicoline is the only neuroprotectant able to improve the functional status of the patients after an acute ischemic stroke. Citicoline is a neuroprotectant drug against cerebral ischemia, with positive results, both in experimental and clinical trials, in the treatment of acute stroke and head injuries Also, the safety profile of citicoline is good, and there are no associated problems when the drug is used in this kind to patients The aim of this study is to confirm the efficacy and safety of citicoline in patients with moderate-to-severe acute ischemic stroke in Egypt, according to the characteristics of the medical care in this country

The investigators propose to infuse healthy autologous mitochondria into cerebral vessels supplying brain tissue experiencing ischemia in patients who undergo standard-of- care endovascular reperfusion therapy.

Mechanical thrombectomy (MT) has shown its effectiveness for the treatment of acute ischemic stroke (AIS) related to large vessel occlusion and rapidly became a cornerstone in the management of these patients. No strong evidence is available on the benefit of MT in AIS related to more distal occlusions. Some previous observational studies suggested a possible benefit but most of them were single-centre and retrospective studies providing a very low level of evidence. To date, no randomized controlled trial has been conducted in this indication, which represents 10% to 20% of all AIS involving intracranial vessel occlusions. This research is a multicenter open randomized controlled trial with two parallel groups : best medical treatment alone VS mechanical trombectomy + best medical treatment.

The clinical study with UMC119-06 is designed to investigate the safety in patients with acute ischemic stroke ("AIS"). This will be a dose escalation, open-label, single-center study in adult with acute ischemic stroke. UMC119-06 is ex vivo cultured human umbilical cord tissue-derived mensenchymal stem cells product which is intended for treatment of acute ischemic stroke.

This study will test the hypothesis that patients presenting within 8 hours of onset with cerebral ischemia in the setting of proximal large vessel occlusions (LVO) and low baseline NIHSS scores (0-5) will have better 90-day clinical outcomes (mRS distribution) with immediate mechanical thrombectomy (iMT) compared to initial medical management (iMM).

The main objective of the study will be to investigate whether treatment with non-invasive vagus nerve stimulation (nVNS) on top of best medical practice in acute ischemic stroke patients results in less infarct growth in the penumbra and smaller infarct volumes compared with those of patients not treated with nVNS. The study will be a prospective randomized clinical trial with blinded outcome assessment (PROBE design). 150 patients will be randomized to nVNS with the gammaCore Sapphire™ device on top of best medical practice versus best medical practice alone (including intravenous thrombolysis and/or thrombectomy if indicated). If patients are randomized to nVNS, two stimulations of two minutes each will be applied in the neck every 15 minutes in the first 3 hours. Thereafter two stimulations will be applied every 8 hours over the next 5 days or until discharge, whichever occurs first. The stimulation side in the neck will be the radiological side of the stroke. The primary endpoint will be the final infarct volume on MRI scan on day 5 of patients treated with nVNS compared with those of patients not treated with VNS.

The purpose of this research study is to determine whether blood pressure treatment regimens with spironolactone are better than blood pressure treatment regimens without spironolactone at lowering blood pressure in stroke survivors.
