Active clinical trials for "Ischemic Stroke"

Currently, dual antiplatelet therapy with aspirin and clopidogrel (with loading doses) is widely used for patients with acute ischemic stroke. However, immediate, potent and reversible inhibition of platelet aggregation is not possible. Additionally, more than 5% patients have aspirin resistance and more than 15% patients have clopidogrel resistance. Therefore, an intravenously administered GPIIb/IIIa receptor inhibitor (Tirofiban) receptor blocker with fast onset and offset of actions will provide more desired antiplatelet effects in the setting of acute ischemic stroke, especially in patients with high risk of neurological deterioration. This study will measure the anti-platelet effects of Tirofiban in patients with acute ischemic stroke who had high risk of neurological deterioration.

This study is a first-in-human assessment of safety of using umbilical cord mesenchymal stem cells (UCMSCs) in patients with Acute Ischemic Stroke via a combination of intra arterial (IA) and intravenous (IV) stem cell administration. The novelty of the current UMSC01 treatment study is the dual route of administration. Since dual administration of UCMSC via IA and IV had never been conducted in humans, there may be unknown risks to humans not predicted from the preclinical studies. However, the risk to patients in this trial will be minimized by rigorous adherence to the eligibility criteria, use of appropriate dose and concentration of stem cells, standardized techniques of stem cell infusion, and intensive patient monitoring during and after stem cell infusion.

The purpose of this study is to evaluate the safety, tolerability, and preliminary efficacy of single injection of it-hMSC in patients with ischemic stroke in a multicenter, blind, randomized, placebo controlled trial

Acute ischemic stroke (AIS) has been one of the major causes of global mortality and morbidity. The superiority of endovascular therapy (EVT) over standard medical therapy in treating AIS due to large vessel occlusion (LVO) in the anterior circulation has been widely accepted. However, a critical concern is that even with an extremely high rate of successful recanalization (the modified thrombolysis in cerebral infarction [mTICI] score 2b-3) around 90%, nearly half of the patients failed to benefit from EVT. So, adjunctive therapy of EVT for neuroprotection is required. From the previous domestic and foreign literatures, hypothermia can prevent and treat secondary injury caused by ischemia-reperfusion injury and cerebral edema of acute cerebral ischemia, so as to achieve the role of neuroprotection. In this study, intravascular cooling was performed as soon as possible with careful temperature control in patients receiving thrombectomy. The temperature was controlled at 33° C for 48-72 hours. This parallel controlled study is to systematically evaluate the feasibility and safety of adjunctive therapy using early intravascular hypothermia in AIS patients receiving mechanical thrombectomy. The results will clarify a potential modality for neuroprotection and hopefully provide new evidence in improving patient prognosis.

The aim of this study is to determine the effects of an intervention using a commercially available probiotic in a cohort of acute stroke patients. In order to determine this, a double blinded, randomised and placebo-controlled study design was chosen.

The purpose of this study is to determine the efficacy and safety of remote ischemic conditioning for acute ischemic stroke.

This study is aiming to evaluate the efficacy and safety of Huatuo Zaizao pill in ischemic stroke patients who diagnosed as the phlegm and blood-stasis blocking collaterals syndrome in TCM. A total of 80 subjects will be randomly assigned to Huatuo Zaizao pill group or the control group.

The purpose of this study is to compare the effectiveness of a 4-week lower extremity telerehabilitation protocol with aims to improve lower extremity function to a 4-week attention-controlled education program on lower extremity clinical outcomes, quality of life, and healthcare resources utilization among community dwelling adults with stroke across Canada.

Phase II, prospective, randomized, multicenter, open-label, pilot clinical trial comparing remote ischemic conditioning (RIC) plus standard medical therapy to standard medical therapy alone, in patients with acute ischemic stroke within 9 hours of stroke onset that are not eligible to recanalization therapies.

This is a placebo controlled, randomized, double blinded study including Phase 1 and Phase 2. Phase I study is a safety assessment and Phase 2 study is incline to assess effectiveness of MSCs. Potential subjects must be screened and consented before enrolled. The primary objective of this study is to determine the effects of early intravenous infusion of allogeneic human umbilical cord mesenchymal stem cells (HucMSCs or MSCs used in the following section) for patients with acute ischemic stroke. Eligible patients will receive a single dose of MSCs or placebo within 24 hours after stroke. Patients will be followed for 2 years post infusion for safety and efficacy (change in neurological symptoms and quality of life). Assessments will occur during transplantation and at 3,7, 14 days and1,3, 6, 12, 18 and 24 months after infusions of stem cells.
