NCT07550257
This observational study aims to investigate the real-world effectiveness and safety of different treatment strategies for acute ischemic stroke (AIS) in Chinese children under 18 years of age. Its primary research question is: In real-world clinical practice, does endovascular therapy (e.g., stent retriever thrombectomy, aspiration thrombectomy) improve 90-day functional outcomes in pediatric AIS patients with acute anterior or posterior circulation large vessel occlusion? Children under 18 years of age receiving routine AIS diagnosis and treatment at approximately 25-35 study centers across China will undergo neurological function assessments, imaging examinations, and evaluations of growth, development, and psychosocial status at baseline, 24 hours post-procedure, 7 days post-procedure or at hospital discharge, and at 90 days and 6 months post-onset. Adverse events will also be documented.
NCT07546448
This study aims to evaluate the relationship between serum electrolyte levels and the development of contrast-induced acute kidney injury (CI-AKI) in patients with acute ischemic stroke undergoing endovascular therapy (EVT). Contrast-induced nephropathy remains a significant complication associated with endovascular procedures and is linked to increased morbidity and mortality. While several risk factors have been identified, the role of serum electrolyte imbalances in the development of CI-AKI has not been fully elucidated. In this retrospective cohort study, patients treated with EVT between 2018 and 2026 will be analyzed. Patients will be classified based on the presence or absence of CI-AKI according to changes in serum creatinine levels. Demographic data, comorbidities, laboratory parameters-including serum electrolytes-and procedural variables will be compared between groups. The primary objective is to determine whether serum electrolyte levels are associated with the risk of CI-AKI. Secondary objectives include evaluating 90-day mortality and dialysis dependency in patients who develop CI-AKI.
NCT07392450
Acute ischemic stroke (AIS) is a medical emergency that happens because of a sudden stop of blood flow to a part of the brain. This happens when a blood clot forms within the vessel (known as thrombotic occlusion) or a clot originating from somewhere else blocks a blood vessel (known as embolic occlusion). Strokes can cause serious health problems, death, and affect one's quality of life. To reduce long-term damage, it is important to restore blood flow to the brain as soon as possible. The main aim of this study is to check how safe TAK-755 is, and how well adults with AIS tolerate it. Other aims are to check how well TAK-755 helps participants to manage their everyday activities and to understand whether it helps reduce the seriousness of their stroke symptoms when compared to placebo. A placebo looks like TAK-755, but does not have any medicine in it, to make sure participants do not know which treatment they are taking. The participants will receive TAK-755 or placebo once; afterwards, their health will be monitored for about 3 months (90 days). All participants, regardless of their assignment to either TAK-755 or placebo, will receive the usual treatment for AIS as per the hospital's normal practice.
NCT07536165

NCT05522569
The purpose of this study is to use an intravenous infusion of allogeneic human mesenchymal stem cells (Allo-hMSCs) to treat an acute ischemic stroke condition.
NCT07519889
This is a multicenter, prospective, non-randomized, post-marketing safety surveillance cohort study with rt-PA (Actilyse®) as the control. It is designed to evaluate the safety of intravenous thrombolysis with recombinant human TNK tissue-type plasminogen activator (rhTNK-tPA, Mingfule®) compared with rt-PA (Actilyse®) in patients with acute ischemic stroke in the real-world setting. This is a non-interventional observational study with no randomization. Treatment decisions are made by treating physicians based on routine clinical practice and the patient's condition. Patients are naturally allocated to the rhTNK-tPA group or the rt-PA group according to the actual thrombolytic drug they receive.
NCT03969511
Rationale: Acute large-vessel strokes, requiring endovascular treatment, are currently being managed through radiology department before being transferred to the angiography room. However, patients with severe neurological deficit have demonstrated even greater benefits from recanalization as the symptom onset-to-reperfusion time is shortened to less than 1 hour. Recent pilot study have shown a benefit in reducing management delays with direct admission to the angiography room and subsequently in increasing functional independence at 3 months. Therefore, the aim is to demonstrate the superiority of the direct angio-suite transfer versus the standard management, in terms of 3-month functional independence, in patients strongly suspected of having a severe ischemic stroke related to acute large-vessel occlusion of the anterior circulation, and treated by mechanical thrombectomy ± intravenous thrombolysis. Methods and Design: The DIRECT ANGIO trial is a (PROBE) randomized, multicenter, controlled, open-label, blinded endpoint clinical trial. Study Outcomes: The primary outcome is the rate of patients with 3-month functional independence defined as modified Rankin Scale score ≤2 at 3 months.
