The purpose of this study is to evaluate whether milvexian compared to placebo reduce the risk of recurrent ischemic stroke.
Intravenous thrombolysis is the first-line therapy in patients with acute ischemic stroke within 4·5 hours of symptom onset, and recombinant tissue plasminogen activator (alteplase) is the preferred thrombolytic agent for this purpose. RhPro-UK is a specific plasminogen activator. rhPro-UK only acts on occlusive thrombus and has little effect on hemostatic thrombus. In addition, rhPro-UK does not form covalent complexes with protease inhibitors in plasma, so the concentrations of rhpro-UK and protease inhibitors in the blood do not decrease compared with alteplase. Therefore, rhPro-UK therapies have a potential advantage of less systemic bleeding in treated subjects. Data from several previous studies suggest that rhPro-UK is efficacious when used to treat patients with acute myocardial infarction. On April 2, 2011, rhPro-UK injection was approved by the National Medical Products Administration to treat acute myocardial infarction. Since then, rhPro-UK has been widely used to treat myocardial infarction in China. Since 2016, we carried a phase 2 clinical trial to explore the dosing of rhPro-UK in patients with acute ischemic stroke, followed by another study with a sample size of 680 patients to initially validate the efficacy and safety of the proposed dose of 35mg. The results of these studies suggested that rhPro-UK was effective, and there were no safety concerns. To further prove the efficacy and safety of rhPro-UK in patients with acute ischemic stroke, we conducted this phase 3 study (PROST-2).
The primary goal of the clinical trial is to test the effect of oral rivaroxaban plus aspirin in patients with recent stroke/ transient ischemic attack (TIA) caused by intracranial artery stenosis. Participants will be divided into 2 groups to receive either oral rivaroxaban plus aspirin or oral clopidogrel plus aspirin. The main question it aims to answer is whether the experimental group (oral rivaroxaban plus aspirin) is superior to the control group ( oral clopidogrel plus aspirin) to lower recurrent stroke/TIA or death in these patients during 1 year of follow-up.
To assess the Efficacy and Safety of Dengzhanxixin Injection in Patients With Acute Ischemic Stroke Receiving Reperfusion Therapy.
To evaluate the safety and tolerability of IxCellhUC-MSC-S as a single intravenous infusion in convalescent patients with ischemic stroke. To explore the efficacy of IxCellhUC-MSC-S as a single intravenous infusion in patients with convalescent ischemic stroke.
The study will collect data from aged 18 to 85 years with a diagnosis of acute stroke, who received thrombolytic treatment with a new agent, nonimmunogenic staphylokinase. Outcomes will be checked for safety and compared to the results of treatment with the other thrombolytic drug, alteplase.
The goal of this clinical trial is to evaluate the effect of evolocumab in combination with statin therapy (atorvastatin) in acute ischemic stroke (AIS).
Vagal Nerve Stimulation is a novel proven therapy for patients with chronic ischemic stroke. The primary objective of this registry is to assess the safety of vagal nerve stimulation for stroke recovery through monitoring the occurrence of serious adverse events associated with the surgical procedure or subsequent paired rehabilitation protocol. This registry will monitor patients undergoing VNS for stroke recovery in the Mount Sinai Health System and collect clinical and procedural details, objective outcomes, and patient-reported outcomes associated with vagal nerve stimulation for stroke recovery.
With the steady development of catheter ablation, it has gradually become the main treatment of various arrhythmias. Antithrombotic and anticoagulant therapy after catheter ablation determines the occurrence of perioperative bleeding and ischemic events. However, the incidence, characteristics and short-term prognosis of secondary acute cerebrovascular events in patients with arrhythmia after catheter ablation have not been studied. Methods: This study was intended to retrospectively collect and analyze the case data and auxiliary examination results of patients with arrhythmia who underwent catheter ablation. To evaluate the incidence, clinical features and short-term prognosis of secondary acute ischemic and hemorrhagic cerebrovascular events in patients with arrhythmia after catheter ablation. In order to improve the quality of life of patients, reduce the secondary acute cerebrovascular complications in the hospital in patients with arrhythmia after catheter ablation, to provide evidence for promoting the clinical management of such patients, and to provide help for the maximum degree of prevention and control risk.
Extensive research is being conducted in search of neuroprotective agents for possible use in the acute phase of stroke and agents that can be used for neurorepair in later stages of stroke. Several trials have been conducted and are in progress using different pharmacological agents, but none of the studies involve the stimulation of ETB receptors to treat cerebral ischemic stroke. Sovateltide (IRL-1620, PMZ-1620) has been effective in animal models of cerebral ischemic stroke. Its safety and tolerability have been demonstrated in a human phase I study with 7 subjects. Clinical phase II and III results indicate that sovateltide is a novel, first-in-class, highly effective drug candidate for treating cerebral ischemic stroke. Safety and significant efficacy in improving the National Institutes of Health Stroke Scale (NIHSS), Modified Rankin scale (mRS), and Barthel index (BI) obtained in phase II and III studies in patients with cerebral ischemic stroke in India are convincing and encouraged us to investigate its safety and efficacy in cerebral ischemic stroke patients in the United States. Therefore, we now plan to conduct a phase III clinical study to evaluate the safety and efficacy of sovateltide therapy along with standard of care in patients of acute ischemic stroke.
