Active clinical trials for "Ischemic Stroke"

The purpose of the study is to determine whether desmoteplase is effective and safe in the treatment of patients with acute ischaemic stroke when given within 3-9 hours from onset of stroke symptoms.

To assess the safety and feasibility of using the NeuroFlo catheter to treat acute ischemic stroke patients following administration of intravenous tPA.

Iron overload has been associated with greater brain injury in ischemia/reperfusion experimental stroke models and ischemic stroke patients, especially in those treated with thrombolytic treatment. Deferoxamine administration, an iron chelator, offers a neuroprotective action in ischemia/reperfusion animal models. Primary objective: To evaluate the security and tolerability of deferoxamine endovenous treatment in acute ischemic stroke patients treated with iv. tPA. Secondary objectives: To study pharmacokinetics of deferoxamine given by endovenous bolus (10 mg/Kg) followed by 72-hour continuous intravenous infusion (20, 40 o 60 mg/Kg). To evaluate the deferoxamine effect in clinical outcome, infarct volume and hemorrhagic transformation and brain edema development. Methodology: Double-blind, randomized, placebo controlled, dose-finding phase II clinical trial. Study stages: 1st: bolus+20 mg/Kg/day vs. Placebo (n=15:5); 2nd: bolus+40 mg/Kg/day vs. Placebo (n=15:5); 3rd: bolus+60 mg/Kg/day vs placebo (n=15:5). These doses will be increased according to security results of the previous stage. Patients will be continuously monitored in stroke units. Laboratory parameters will be measured at baseline, 24h, 72h and 30 days to evaluate adverse events related to the drug. Serum deferoxamine and feroxamine concentrations will be measured along time after the injection in a subgroup of patients to the pharmacokinetics study. CT scan will be performed at 24-36h to assess hemorrhagic transformation and brain edema. The NIH Stroke Scale will be evaluated during hospitalization, and the Rankin score at discharge and 3 months. If deferoxamine demonstrate to be secure and well tolerated treatment in acute stroke patients, it may be a new therapy option to lower the brain injury after ischemia and reperfusion.

This study will determine the effectiveness of a specialized psychotherapy for treating elderly stroke survivors who are depressed.

The purpose of this study is to determine whether the clinical pathway for acute ischemic stroke(with combination of traditional Chinese medicine and western medicine) is able to improve the outcome of acute ischemic stroke and evaluate its effect on hospital day and cost, etc. Meanwhile, the study will discuss the safety and efficiency of this kind of Clinical Pathway

The primary objective of this study is to demonstrate the safety and efficacy of the PFX Closure System when utilized for patent foramen ovale (PFO) in patients suffering from cryptogenic stroke (undetermined cause of stroke), transient ischemic attack (brief neurological dysfunction), migraine or decompression illness.

The ultimate goal of this multicenter, phase II study is to increase blood pressure until either a neurologic response is seen or a target mean arterial pressure of 30% above baseline is achieved. IV fluids, IV phenylephrine and/or IV norepinephrine are used to rapidly raise mean arterial pressure in a controlled manner as serial assessments of neurologic function are performed.

The purpose of this study is to study efficacy and safety of cilostazol use in patients with acute ischemic stroke.

To evaluate the safety profiles of HTU-PA in patients with acute ischemic stroke.

The AXIS study is a randomized, double-blind, placebo-controlled, dose-escalating phase IIa trial to investigate treatment with AX200 (granulocyte-colony stimulating factor; G-CSF) for acute ischemic stroke. The primary objective of the present phase IIa study is to assess the safety and tolerability of AX200 compared to placebo in subjects suffering from acute stroke. The secondary objective is to assess the effect of AX200 on subject outcome in comparison to placebo.
