Active clinical trials for "Brain Ischemia"

Neonatal hypoxic-ischaemic encephalopathy is a dramatic perinatal complication due to brain asphyxia. Neurological and neurosensory sequelae are frequent in survivors, due to neuronal damage and loss. Currently, only total or partial body hypothermia can partially prevent cell loss. However, no treatment exists to restore neuronal functions. Cord blood stem cells are a promising treatment for the near future. The primary objective of this study is to test the safety and feasibility of a curative treatment with autologous cord blood stem cell in neonatal hypoxic-ischaemic encephalopathy. The secondary objectives are to test the efficacy of this curative treatment with cell with neurogenic potential on the prevention of neurologic sequelae, as well as to test the optimum timing of cell preparation administration

A multicenter, randomized, adaptive allocation clinical trial to determine if increasing durations of induced hypothermia are associated with an increasing rate of good neurological outcomes and to identify the optimal duration of induced hypothermia for neuroprotection in comatose survivors of cardiac arrest.

The overall incidence of good outcome for AIS following endovascular treatment is only proximately 50%. Whether NBO was safe and effective to improve acute ischemic stroke prognosis is still unclear. The investigators' hypothesis is thatNBO is a safe and effective strategy to improve longterm outcome in AIS patients undergoing endovascular treatment.

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.

Management of neonatal pain and sedation often includes opioid therapy. A growing body of evidence suggests long-term harm associated with neonatal opioid exposure. Providing optimal sedation while neonates are undergoing therapeutic hypothermia (TH) may be beneficial but also presents therapeutic challenges. While there is evidence from animal models of brain injury and clinical trials in adults to support the safety and neuroprotective properties of dexmedetomidine (DMT), there are no published large clinical trials demonstrating safety and efficacy of DMT use in neonates with hypoxic-ischemic encephalopathy (HIE) during treatment with TH. This study is innovative in proposing a Phase II, 2-arm trial providing the opportunity to evaluate the use of DMT as compared to the use of morphine for sedation and pain management for babies undergoing TH. We propose to confirm optimal DMT dosing by collecting opportunistic pharmacokinetics (PK) data and determine safety of DMT in this population. These data will inform a larger phase III efficacy trial.

This is a prospective, single center, pharmacokinetic study of intravenous hydrocortisone therapy for systemic low blood pressure during hypothermia treatment in asphyxiated newborns. Patients will be allocated to hydrocortisone supplementation while receiving conventional inotropic therapy as needed. The hypothesis is that a detailed study of hydrocortisone pharmacokinetics during therapeutic hypothermia would help to personalize steroid supplementation in asphyxiated neonates. As the overall metabolic rate decreases with lower body temperature, drug metabolism is likely to be reduced as well, and lower doses, or less frequent dosing will be sufficient to achieve the targeted steroid range and biological effects in asphyxiated neonates with relative adrenal insufficiency. Thus, the investigators are planning to measure initial, baseline serum cortisol levels and serial serum cortisol levels after hydrocortisone supplementation in cooled asphyxiated neonates.

The present study is a randomized, multi-center, double-blind, prospective study that tests the efficacy of intravenous milrinone to optimize cerebral hemodynamic and prevent delayed cerebral ischemia (DCI) during the high-risk period (day 4- day 14) in patients with severe subarachnoid hemorrhage due to intracranial aneurysm rupture (SAHa) (WFNS IV-V). The main objective is to evaluate, in comatose patients and / or sedated on D3 following a severe SAHa (WFNS IV -V), the effect of 10 days of milrinone versus placebo, in addition to the usual management, on the volume of DCI lesions measured on CT scan at 1 month.

The main purpose of this study is to determine the maximum safe tolerated dose of LEV in the treatment of neonatal seizures. Our hypothesis is that optimal dosing of Levetiracetam (LEV) to treat neonatal seizures is significantly greater than 60mg/kg. This study will be an open label dose-escalation, preliminary safety and efficacy study. There will be a randomized control treatment component. Infants recognized as having neonatal seizures or as being at risk of developing seizures will be recruited and started on continuous video EEG monitoring (CEEG). Eligibility will be confirmed and consent will be obtained. In the first 2 phases of the study, neurologists will identify neonates with mild-moderate seizure burden (less than 8 minutes cumulative seizure activity per hour), appropriate for study with LEV, and exclude patients with higher seizure burden where treatment with PHB is more appropriate. Phase 3 of the dose escalation will only proceed if additional efficacy of LEV has been demonstrated in phases 1 and 2. In Phase 3 we will recruit neonates with seizures of greater severity up to 30 minute seizure burden/hour. This will make the final results of study more generalizable. If seizures are confirmed, enrolled subjects will receive 60mg/kg of LEV. Subjects whose seizures persist or recur 15 minutes after the first infusion is complete, subjects will then be randomized in the dose escalation study. Patients in the dose escalation study will be randomly assigned to receive either higher dose LEV or treatment with the control drug PHB in a 3:1 allocation ratio, stratified by site.

Sovateltide (PMZ-1620; IRL-1620) is targeted to be used as a "Treatment for hypoxic-ischemic encephalopathy in neonates," which is a life-threatening condition. Sovateltide augments neuronal progenitor cell differentiation and better mitochondrial morphology and biogenesis to activate a regenerative response in the central nervous system. The only treatment for HIE is therapeutic hypothermia with limited success, and studies indicate that sovateltide may be beneficial in these patients.

This is a human clinical study involving the isolation of autologous bone marrow derived stem cells (BMSC) and transfer to the vascular system and inferior 1/3 of the nasal passages in order to determine if such a treatment will provide improvement in neurologic function for patients with certain neurologic conditions. http://mdstemcells.com/nest/
