Active clinical trials for "Ischemic Stroke"

Use of intravenous(IV) thrombolysis and intra-arterial(IA) recanalization treatment has been rapidly increasing, However, despite of the treatment, recanalization rates are 22.6 - 70% and only 30-50% of patients show meaningful clinical improvements. Mechanisms of futile recanalization may include 1) large ischemic core, 2) poor collateral, and 3) presence of comorbidity. In this regards, developing selection criteria using acute stroke imaging and comorbidity is warranted. The investigators will recruit the consecutive acute stroke patients who received IV thrombolysis and/or IA recanalization treatment. This study will perform with prospective design to develop CT-based clot, core and collateral scores and a comorbidity index for selecting stroke patients who are at high risks by the treatment. The investigators will firstly establish the CT-based scores and comorbidity index using a pre-existing cohort database. Using these CT-based and comorbidity index, the investigators will validate them in a multi-center prospectively cohort.

The main objective of the PROOF trial is to investigate efficacy and safety of normobaric hyperoxygenation (NBHO) as a neuroprotective treatment in patients with acute ischemic stroke due to large vessel occlusion likely to receive endovascular mechanical thrombectomy (TBY) in a randomized controlled clinical phase IIb trial.

A study of stereotactic, intracerebral injection of CTX0E03 neural stem cells into patients with moderate to moderately severe disability as a result of an ischemic stroke.

The study is designed to explore the efficacy and safety of head-down position in patients with acute ischemic stroke。

Study objective is to evaluate the efficacy and safety of acute permanent stenting of symptomatic intracranial stenosis following unsuccessful recanalization by thrombectomy in acute ischemic stroke with large vessel occlusion using the self-expandable Credo® stent together with the NeuroSpeed® PTA balloon catheter.

After intravenous thrombolysis, the overall recanalization rate is 46%, and recclusion after initial recanalization occurs in 14-34%. In the MR TEA, the investigators compared the effects of administration of tirofiban in acute ischemic stroke patients treated with intravenous alteplase thrombolysis with alteplase alone.

Patients with acute ischemic stroke in anterior circulation within 4,5 hours of symptom onset, has a bone window and Trombolysis In Brain Ischemia (TIBI) <=4 in a relevant artery eligible. Both patients receiving thrombolysis and those who do not due to contraindications such as anticoagulation or recent surgery are enrolled, but into different study arms (CE-5S A for thrombolysis and B for non-thrombolysis); the decision to treat with thrombolysis or not is done according to clinical routine. All included patients are randomized to receive transcranial ultrasound and SonoVue-infusion or sham-ultrasound and placebo; i.e. in CE-5S A, contrast enhanced sonothrombolysis is compared to thrombolysis and in CE-5S B, contrast enhanced sonolysis is compared with conservative management. Main outcome is improvement in National Institute of Health Stroke Scale (NIHSS) at 24 hours compared to baseline. Main safety outcome is symptomatic intracerebral haemorrhage.

The main aim of this project is to demonstrate an association between gut and oral microbiota and their metabolites to carotid atherosclerosis and risk of ischemic stroke. The investigators aim to show that these metabolite levels are diet-dependent (mainly egg yalk and red meat) and associated with specific types of microbiota. The investigators to assess serum microbiota metabolite levels as a predictor of stroke and plaque progression for patients with carotid atherosclerosis.

PRAAN is a post-market registry designed to collect real-world data associated with the use of Medtronic market release neurothrombectomy devices in acute ischemic stroke (AIS) patients from India.

This study will assess the impact of fever prevention on fever burden and short- and long-term neurologic outcomes in brain injured patients. Half of the subjects will undergo fever prevention using a targeted temperature management system and half of the subjects will be treated for fever should it develop.
