Active clinical trials for "Ischemia"

The main objective is to evaluate the efficacy of IV administration of the P2Y12 inhibitor (cangrelor) in addition to mecanich thrombectomy and WMD versus mecanich thrombectomy and WMD alone on the functional prognosis at 3 months, in patients with acute ischemic stroke eligible for mecanich thrombectomy on the basis of infusion imaging between 0 and 24 hours after the onset of symptoms.

This is a prospective, multicenter, single arm study designed to evaluate the safety and efficacy of the Temporary Bare Spur Stent System (Spur Stent System).

The scientific hypothesis was based on data on the effectiveness of the usage of robotic mechanotherapy and virtual reality technologies. Purpose of the study is the development and scientific substantiation of the effectiveness and safety of rehabilitation programs using the technology of robotic mechanotherapy (exoskeleton) with functional electrical stimulation (FES) and virtual reality (VR) technology with biofeedback (BFB) in restoring walking and balance disorders at the stationary stage of medical rehabilitation in patients in acute and early recovery periods of ischemic stroke. The duration of the study is 2 years. The study is planned to include 120 patients. Anamnesis collection, physical and neurological examination will be carried out for all patients upon admission. Diagnostic transcranial magnetic stimulation, electroencephalography and stabilometry will also be performed upon admission and discharge. Adverse events will be assessed. On the last day of the study, the dynamics of the volume and strength of movements, functional independence and spasticity will be assessed according to the scales (MRC, NIHSS, mAS, mRS, Rivermead, Hauser walking index, Tinetti scale, SHRM, ICF, Tampa scale, EQ-5D-5L), as well as the assessment of mental and cognitive status according to HADs and MoCA. Patients will be randomly divided into 4 groups: 3 main and 1 control. All patients will undergo a basic rehabilitation course. In the first group (exoskeleton with FES): 10 procedures, 5 times a week, the duration of the course of medical rehabilitation is 12-14 days. The total duration of one procedure is 1 hour. In the second group (VR technologies with BFB): 10 procedures, 5 times a week, the duration of the course of medical rehabilitation is 12-14 days. The total duration of one procedure is 30 minutes. In the third group (Complex application of robotic mechanotherapy technologies with FES and VR with biofeedback): 10 procedures, 5 times a week, the duration of the course of medical rehabilitation is 12-14 days. The total duration of training with VR is 30 minutes, then no earlier than 2 hours later, training on an exoskeleton, lasting no more than 1 hour. Patients in the control group will receive comprehensive rehabilitation procedures as prescribed, during the course of treatment accepted in a medical institution.

Endovascular treatment（ET）is an effective therapy for acute ischemic stroke(AIS) with great vessel obstruction. However, acute complications such as high postoperative perfusion injury, hemorrhagic transformation and restenosis resulted in functional independence in only about 50% of patients 90 days after interventional surgery. Therefore, it is very important to protect the neurologic function after emergency endovascular treatment. The investigators' previous studies have shown that combined with intravenous thrombolytic therapy and remote postconditioning（RIPC）can significantly improve the neurological impairment and short-term and long-term prognosis in patients with acute stroke. In this multicenter, randomized controlled trial, the investigators assumed patients with acute ischemic stroke who had successfully revascularization after ET might benefit from RIPC as well. Patients in the RIPC group had five cycles of 5-min cuff inflation followed by 3-min deflation to the bilateral upper arm after ET. The primary endpoint measure was the proportion of patients with a favorable recovery of nerve function deficient assessed by Modified Rankin Scale （mRS≤2） 90 days after surgery. Secondary endpoints included the following: (1) Symptom endpoints: Neurological intelligence and function scores, postoperative hemorrhagic transformation rate, etc. (2) Blood index test: postoperative inflammatory factors, neuron-specific enolase (NSE) and other indicators. (3) Imaging endpoints: MRI-FLAIR , TCD, etc.

The purpose of this study is to investigate the safety and efficacy of low-dose (50mg) aspirin as a secondary prevention drug in patients with Non-Cardioembolic Ischemic Stroke accompanied by cerebral microbleeds.

Through the implementation of prospective, multi-center, randomized, parallel controlled clinical studies to verify the safety and effectiveness of Hongyuan thrombolysis device system in the intravascular treatment of acute ischemic stroke. According to the requirements of the experiment, 200 subjects were selected and randomly divided into the experimental group and the control group 1:1. According to the information of the group, corresponding devices were used to receive endovascular therapy and the results were evaluated.

This study aims to evaluate the efficacy of Y-6 sublingual tablets in improving microcirculation dysfunction and reducing thrombo-inflammation in patients who had AIS caused by LVO and received reperfusion therapy. Moreover, we expect to evaluate the safety of using Y-6 sublingual tablet in such study population.

The Oxiris membrane is an AN-69 membrane whose surface is treated with polyethyleneimine (PEI) grafted with heparin. This property allows the removal of lipopolysaccharide and cytokines from the blood. During septic shock, this membrane has shown its effectiveness and made it possible to decrease the doses of vasopressors administered, thus limiting the negative consequences of their use (low mesenteric flow in particular). Moreover, the literature suggests that the use of the Oxiris membrane does not lead to side effects or specific and serious complications, in comparison with conventional extra-renal purification membranes. To our knowledge (Pubmed, clinicaltrial) there are no data in patients in cardiogenic shock assisted by ECLS. The research hypothesis is that the early addition of an Oxiris membrane to the ECLS circuit allows the removal of lipopolysaccharides and pro-inflammatory cytokines, thus controlling the inflammatory cascade and limiting vasoplegia and organ failure.

Mechanical thrombectomy is a very effective treatment in patients who have suffered an acute ischemic stroke associated with intracranial large vessel occlusion. However, less than half of the patients achieve functional independence despite treatment. The optimization of blood pressure after mechanical thrombectomy based on the degree of recanalization achieved at the end of the procedure could improve the perfusion of the ischemic brain tissue thanks to the improvement of blood circulation provided by collateral circulation. For this, authorized hypotensive or hypertensive drugs will be used. Moreover, this individualized treatment would allow to decrease reperfusion injury and therefore decrease the risk of intracerebral bleeding complications and cerebral edema. Therefore, we designed a clinical trial in which the standard management of blood pressure after mechanical thrombectomy will be compared with a specific protocol in which blood pressure targets are applied according to the degree of recanalization obtained during the thrombectomy procedure. The beneficial effect and risk reduction of this treatment will translate into a better short and long-term outcome

The investigators conduct this study to investigate whether oral administration of Dimethyl Fumarate, a Food and Drug Administration-approved drug for multiple sclerosis, is safe and effective in combination with alteplase in patients with Acute Ischemic Stroke.
