Filter by:This study is a multicenter, randomized, double-blind, parallel, placebo-controlled trial design to evaluate the efficacy and safety of the KPCXM18 injection at different doses for the treatment of acute ischemic stroke and its PK/PD characteristics in patients.
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.
The purpose of this study is to determine the efficacy and safety of levofloxacin combined with endovascular thrombectomy in treating acute ischemic stroke due to large vessel occlusion of anterior circulation.

It is a retrospective cross-sectional study, where consecutive stroke patients with vessel occlusion on magnetic resonance angiography (MRA) will be included for the study for one year. The relation of Susceptibility vascular sign (SVS) on Susceptibility Weighted Imaging (SWI) with risk factors and territory involved and length of thrombus will correlated with the National Institutes of Health stroke scale (NIHSS).Among total number of patients included in this study the demographics of the patients will be calculated. Risk factors for stroke of the patients included in this study will tabulated. The site of occlusion will be tabulated. The mean NIHSS scale will be calculated. Presence of SVS in patients with MR angiography positive vessel occlusion will be calculate in percentage. Subgroup analysis of presence of SVS on SWI will be done. The mean length of the thrombus will be calculated in these patients with positive SVS. Correlation between SVS on SWI with the risk factor of the patient by using the chi-square test will be calculated. A Chi-square test will be done to find out the correlation between the SVS with territorial occlusion. The correlation between the NIHSS score and length of thrombus will be calculated using the Pearson test. SWI can be useful in identifying the location of the thrombus, and NIHSS can determine the thrombus length in acute stroke. A higher incidence of SVS can be associated with risk factors and it also depends upon the site of occlusion of the vessel.
In this study, satralizumab will be administered to see whether satralizumab is safe in patients with a burst brain aneurysm and if it may prevent strokes in patients with a burst brain aneurysm.
Background: Recanalization strategies have radically changed the outcome in a significant part of stroke patients. The unpredictable occurrence of cerebral edema (CE) and hemorrhagic transformation (HT) are frequent events in patients affected by ischemic stroke, even when an effective vessel recanalization has been achieved. These complications, related with blood brain barrier (BBB) disruption, remain difficult to prevent or treat, and antagonize the beneficial effect of successful recanalization, leading to poor outcome. Aim: to shed light on the reperfusion injury biological bases, this study aims at evaluating the effects of circulating and imaging biomarkers in relation to CE and HT both in stroke patients and in a coherent murine stroke model. A close interaction between clinical and preclinical research could lead to a broader understanding of the results deriving from the individual lines of activity, allowing a deeper interpretation of the underlying phenomena. Methods: The clinical setting is a retrospective observational study enrolling consecutive patients with acute ischemic stroke in the anterior circulation territory, treated with reperfusion therapies, at Careggi University Hospital in Florence (Italy) from October 1, 2015 to May 31, 2020. In this cohort, the investigators will apply a new approach to assess the presence of CE and HT after stroke in CT scans, through the quantification of anatomical distortion (AD) (induced by fluid extravasation in brain tissue) at 24 hours. A large panel of blood biomarkers related to inflammation, endothelial dysfunction , and fibrin resistance to lysis, will be measured as blood samples are taken from each patient before and 24 hours after thrombolysis or thrombectomy. The role of both AD and blood biomarkers as predictors of 3 months functional outcome, assessed by modified Rankin Scale (mRS), will be estimated. Using a translational approach the investigators will develop a new mouse model of light-induced occlusion/reperfusion of the middle cerebral artery (MCA) to better reproduce the human setting. Then, the investigators will assess functional impairment induced by stroke with and without recanalization at different time points and the investigators will assess through ex vivo experiments the insurgence of BBB alterations 24 hours after the lesion. Finally, the investigators will characterize the stroke volume and the inflammation one week after stroke.
First prospective, single-arm, single-centre study to evaluate the efficacy and safety of the iNstroke thromboaspiration catheter system (iNstroke) for stroke in patients with acute ischemic stroke.
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 is a forward-looking, open, one-arm, and real clinical trial world. The researchers plan to recruit at least 50 qualified patients. The main purpose of this study is to establish a population pharmacokinetic model of ticagrelor , explore the correlation between its blood concentration and the events of ischemia and the adverse effects of hemorrhage, and evaluate the effectiveness and safety of ticagrelor in the treatment of ischemic cerebrovascular disease.
