NCT ID: NCT03433235 Not yet recruiting - Clinical trials for Acute Ischemic Stroke

Early Administration of Edoxaban After Acute Ischemic Stroke in Patients With Non-valvular Atrial Fibrillation

Start date: March 31, 2018
Phase: Phase 2
Study type: Interventional

The investigators hypothesize that earlier initiation of edoxaban in AF-related stroke patients may significantly reduce the early recurrence of ischemic stroke, compared with conventional strategy of anticoagulation following 1-3-6-12 rule. To expedite the verification of the hypothesis, the investigators are planning to use diffusion weighted imaging (DWI), which has been reported to be a surrogate to predict both short-term and long-term prognosis after stroke, to detect the recurrent ischemic events. Because data on the early anticoagulation in patients with AF-related stroke are limited, the investigators decided to perform a pilot study before establishing an appropriate clinical trial protocol. This study will help estimate the efficacy and safety of early administration of edoxaban, and determine the sample size of a following clinical trial. To ensure the safety in this pilot exploration, the investigators will not include patients with severe ischemic strokes, who are often prone to experience hemorrhagic transformation in the acute post-stroke period.

Evaluation Of HUK in Acute Stroke Patients: MRS and CTP

Start date: January 1, 2014
Phase: Phase 4
Study type: Interventional

Background: Acute ischemic stroke (AIS) is a leading cause of morbidity and mortality worldwide. Human urinary kallidinogenase (HUK), a glycoprotein extracted from male urine currently used in China for enhancing cerebral perfusion5, plays a neuroprotective role including promoting angiogenesis, enhancing cerebral perfusion and suppressing the inflammatory response in animals and in patients with respect to regulating the kallikrein-kinin system. In previous clinical research, neurological function scores and cerebral perfusion scans were largely used to evaluate the efficiency of HUK. However, the mechanisms of Further well-conducted, randomized controlled studies using HUK are currently lacking. Objective: To assess the Human urinary kallidinogenase effects on brain metabolite and cerebral perfusion changes using magnetic resonance spectroscopy and CT perfusion in patients with AIS. Methods: The investigators plan to do a single-centre randomized, double-blind, controlled trial in which ischemic stroke patients will be randomized to treatment with either HUK or regular treatment within 72 hours of symptom onset. The study includes two MRS and two CTP scannings (before and after 2 week treatment) for all randomized subjects. The endpoints will include improvement of the NIH Stroke Scale (NIHSS) score from baseline, modified Rankin scale (mRS) score and Barthel index at 14 days. EvHUKMRS will test the following hypotheses: 1. HUK enhanced N-acetylaspartate (NAA) and cerebral blood flow (CBF) 14 days after treatment compared with control group. 2. HUK group compared to control group when administered 72 hours after onset of AIS improves recovery and functional outcome as assessed by improvement of NIHSS score , mRS score and BI score on day 14 post-stroke. A positive result will have a significant impact in the management of AIS and pave the way for future studies aimed at finding the optimal dose and formulation of HUK for treating acute ischemic stroke.

Effectiveness of Butylphthalide on Dynamic Cerebral Autoregulation in Patients With Acute Ischemic Stroke.

Start date: January 2018
Phase: Phase 4
Study type: Interventional

This is a randomized, triple-blind, placebo-controlled, multicenter clinical trial. investigators plan to enroll 774 eligible patients, which will be randomized into either the butylphthalide (NBP) or placebo group in a 2:1 ratio.The main purpose of this study is to determine whether butylphthalide can improve dynamic Cerebral Autoregulation (dCA) in large-artery atherosclerosis acute ischemic stroke.

German Stroke Registry - Endovascular Treatment

Start date: June 2015
Phase: N/A
Study type: Observational [Patient Registry]

The German Stroke Registry (GSR) Endovascular Treatment is an academic, independent, prospective, multicentre, observational registry study. Consecutive patients treated with endovascular stroke treatment will be enrolled in German stroke centers. Patients receive regular care and data will be collected as part of clinical routine. Baseline clinical and procedural information as well clinical follow-up information during in-hospital stay, and up to 90 days of stroke onset are collected. Data collected include demographics, National Institute of Health Stroke Scale (NIHSS) on admission, pre-treatment ASPECTS, information on timing and success of interventional treatment, procedural complications, intracranial hemorrhage, and functional outcome.

Dose Finding Study of MCI-186 in Acute Ischemic Stroke

Start date: November 17, 2017
Phase: Phase 2
Study type: Interventional

To investigate the efficacy and safety of MCI-186 (bolus followed by continuous infusion) in acute ischemic stroke patients through a double-blind, parallel-group comparison with the existing MCI-186 dosing regimen (administration twice daily for 14 days) as the control.

Predictive Significance of TEG on END in Patients With Acute Ischemic Stroke

Start date: June 1, 2016
Phase: N/A

The purpose of this study is to evaluate whether Thromboelastography (TEG) parameters on admission might be predictive for early neurological deterioration in acute ischemic stroke patients, specifically for the DWI lesion evolution within the first week after stroke onset.

NCT ID: NCT03297827 Recruiting - Ischemic Stroke Clinical Trials

Cytokine Registry Database of Stroke Patients

Start date: January 1, 2018
Phase: N/A
Study type: Observational [Patient Registry]

Various molecules (cytokines: interleukins, interferons and neural proteins) found in human and animal blood are reported to be elevated in acute stroke (Ischemic and hemorrhagic). Cytokines can be pro-inflammatory or anti-inflammatory. There are studies confirming level changes in serum of humans in the setting of several rheumatologic and cardiovascular diseases. As new molecular markers (cytokines and neural tissue markers) are established in scientific literature, stroke scientists are interested to evaluate the role of these in the pathophysiology of stroke. Investigators intend to study the role of these molecules in the development of stroke. Acute stroke treatment has advanced considerably in the last 10 years with the establishment of comprehensive stroke centers and approval of neuro-interventional techniques. However, the molecular advancement in stroke pathogenesis has yet to reach a milestone in the world of stroke treatment. In our opinion, creating a database of acute stroke patients containing all pertinent medical demographics and clinical information along with the laboratory data, molecular levels of pertinent cytokines/neural factors from consenting patients, will help us define and delineate the most relevant molecules that are altered in acute stroke patients and can help us further improve us understanding of the role of these in acute stroke and thereby hopefully help in the improvement of our understanding and management of stroke. Moreover, analyzing the cytokines in stroke and ICH patients would help understand their role in the acute phase, which may become potential therapeutic adjuncts for tPA and endovascular thrombectomy.

NCT ID: NCT03290885 Recruiting - Clinical trials for Acute Ischemic Stroke

Combined Use of Contact Aspiration and the Stent Retriever Technique Versus Stent Retriever Alone for Recanalisation in Acute Cerebral Infarction

Start date: October 16, 2017
Phase: N/A
Study type: Interventional

Mechanical thrombectomy (MT) with a stent retriever (SR) device is now the standard intervention in ischemic stroke with large vessel occlusion. Favorable outcome is strongly associated with the successful reperfusion status. New device of MT such as contact aspiration seems promising to increase reperfusion status and clinical outcome. The main hypothesis is to show the superiority of combining the use of contact aspiration with a stent retriever compared to a stent retriever alone in treatment of acute stroke due to proximal arterial occlusion. The primary endpoint is the rate of perfect reperfusion score at the end of the endovascular procedure.
