Filter by:This study is designed to determine the safety and efficacy of SHPL-49 intravenous infusion for 7 consecutive days in the treatment of acute ischemic stroke subjects.
The objective of this study is to create a comprehensive, multi-center, TRACK-LVO registry-linked cohort of consecutive patients with acute ischemic stroke (AIS) caused by large vessel occlusions (LVO) and presenting to each participating center beyond 24 hours from last known well, who are treated with either endovascular therapy (EVT) or the best available medical management (BMM).
The purpose of this study is to to compare the safety and effectiveness of IV urokinase with IV alteplase in the treatment of AIS in patients up to 6 hours from symptom onset.
The study is planned to evaluate the effectiveness and safety of two types of anesthesia (regional and general) for carotid endarterectomy in 100 patients with acute stage of stroke: 50 patients will be operated under regional anesthesia and the remaining 50 patients under general anesthesia. Patient inclusion criteria: 1. Ischemic stroke in the middle cerebral artery territory 2. Ipsilateral stenosis of the internal carotid artery more than 50% 3. Neurological deficit at the time of surgical treatment: the modified Rankin scale (mRs) score of 0-4 and the US National Institutes of Health (NIHSS) stroke scale score no more than 12 4. The size of the ischemia focus: no more than 1/3 in the territory of the middle cerebral artery brain supply 5. Terms of operation: from 1 to 28 days from the moment of ischemic stroke The primary intra-hospital and/or 30-day study endpoints: 1. Perioperative ipsilateral ischemic stroke. 2. Any stroke: contralateral ischemic or any hemorrhagic stroke. 3. Myocardial infarction. 4. Hemorrhagic complications that required surgical revision of the operating wound or transfusion of blood components. 5. Surgical site infection 6. Death 7. Main adverse cardiovascular events (stroke + myocardial infarction + death).
This study will critically examine the feasibility, safety and efficacy of HBOT during inpatient rehabilitation (IPR) after acute ischemic stroke measured by non-disruption of 3 hours of daily therapy, frequency of neurological deterioration or complications (seizure, hemorrhage, brain edema), and functional communication, activities of daily living (ADLs) and mobility.
Rationale: Distal Medium Vessel Occlusion (MeVO) are thought to cause as many as 25% to 40% of all acute ischemic strokes (AIS). Despite their relatively high frequency, there is no consensus regarding the optimal management of these patients. However, the fact that AIS related to MeVO often results in significant disability despite best medical treatment (including intravenous thrombolysis, IVT) calls for novel treatment approaches. Fortunately, a growing number of non-randomized studies have now been published demonstrating the feasibility of endovascular treatment (EVT) for MeVO strokes. These studies have demonstrated that distal EVT leads to high rates of successful reperfusion and may be performed with a comparable safety profile to that of EVT for proximal arterial occlusions. Therefore, a strong rational exists to test the safety and efficacy of EVT for MeVO stokes in a prospective randomized clinical trial. Objectives: The primary objective of this study is to evaluate the hypothesis that endovascular thrombectomy is superior to standard medical management in achieving more favorable outcomes according to the modified Rankin Scale scores at 90 days in subjects presenting with acute ischemic stroke related to a distal medium vessel occlusion within 24 hours from symptom onset (defined as time last know well, TLKW). Secondary objectives include the assessment of the cost-effectiveness of endovascular thrombectomy in the medium vessel occlusion (MeVO) population as well as its impact on health-related quality of life. Study design: The study is a prospective, multicenter, investigational, randomized, controlled, open-label study with blinded endpoint evaluation (PROBE design) and an adaptive design with population enrichment. Study population: Subjects presenting with acute ischemic stroke within 24 hours from TLKW and whose strokes are attributable to a distal medium vascular occlusion defined as co/non-dominant M2 segment or M3 segment of the MCA, the ACA (A1, A2, or A3 segments), or the PCA (P1, P2 or P3 segments) with evidence of salvageable brain tissue on perfusion imaging, M2 segment vessel diameter should not exceed 2.0 mm. Primary outcome: Shift in distribution of all levels of the 90-day the modified Rankin Scale with levels 5-6 combined (mRS; 0, 1, 2, 3, 4, 5-6) as assessed by structured assessment.
Patients presenting with mild symptoms of acute ischemic stroke are common and account for approximately half of all acute ischemic stroke. About 30% of patients with minor stroke have a 90-day functional disability. Radiologically proven a large vessel occlusion (LVO) in patients with minor stroke is a well-established predictor of poor outcomes, while the poor outcomes following best medical management in patients with minor stroke with the underlying presence of a LVO are mainly driven by the occurrence of early neurological deterioration (END). Considering the well-known strong association between lack of arterial recanalization and END, endovascular therapy (EVT) appears as an attractive option to improve functional outcomes for LVO-related patients with stroke with mild symptoms. Whether EVT is safe and effective in patients with mild stroke with an LVO is currently debated, since these patients were typically excluded from the pivotal EVT trials. The current study aimed to further test the hypothesis that endovascular therapy would be superior to medical management with respect to functional recovery among low NIHSS patients caused by acute large-vessel occlusion in the anterior circulation.
This study aims to conduct a multicenter, prospective, randomized clinical trial to scientifically evaluate the safety and efficacy of different perioperative sedation methods during endovascular thrombectomy in acute ischemic stroke patients with large vessel occlusion in the anterior circulation.
This is a multicenter, randomized, double-blinded, placebo-controlled, dose-escalation trial. The objective of this study is evaluating safety and preliminary efficacy of intravenous exosomes derived from human induced pluripotent stem cell (GD-iExo-003) in acute ischemic stroke.
The primary objective of this study is to evaluate the functional recovery based on Barthel index (BI) and modified Rankin Scale (mRS) while the secondary objectives are to assess the survival and re-admission rate as well as to investigate the inflammatory response in a subclinical study within 1 year of Neuroncell-EX infusion in participants with acute ischemic stroke.
