Active clinical trials for "Ischemic Stroke"

The primary purpose of this study is to determine whether a brief intravenous infusion of ancrod started within 6 hours of stroke onset improves functional outcome at 3 months.

THRACE is a controled, multicenter and randomized trial. The primary objective of this study is to determine whether a combined approach intravenous thrombolysis (IV) + Mechanical thrombectomy is superior to the reference treatment with IV thrombolysis alone, in the 3 hours of onset of symptoms in patients with occlusion of proximal cerebral arteries and with a neurological impairment accident (National Institutes of Health Stroke Scale [NIHSS] ≥ 10). The second objective is to determine the cost-effectiveness of this procedure compared to the standard (IV thrombolysis). The assumption is that the combined approach, by improving the clinical outcome and speed recovery, allows for lower overall costs to the IV thrombolysis in 3 months and less than or at worst neutral to 1 year.

Randomized controlled clinical trial to estimate overall treatment benefit (improvement in disability) among stroke patients treated with rt-PA who are randomized to also receive either low-dose Argatroban, high-dose Argatroban or neither.

The purpose of this study is to determine which of 3 different doses of tenecteplase (TNK) is better for treating stroke patients and if TNK offers an advantage over currently available treatment with tissue plasminogen activator (tPA).

A prospective, open label single arm feasibility study to evaluate the safety and performance of the Magneto Wire in patients diagnosed with acute ischemic stroke and planned for thrombectomy procedure.

CASTRO1 is a study to investigate the reduction of C-reactive protein (CRP) by therapeutic apheresis (CRP-apheresis) in patients after primary treatment of ischemic stroke. The term therapeutic apheresis commonly refers to medical procedures, where pathogenic constituents are being removed from the circulating blood. Elimination is performed by adsorbers outside the body in an extracorporeal circulation. For removal of the pathogenic substances the plasma is separated from the blood (circulation) to pass the adsorber. The purified plasma is merged with the solid blood components thereafter and returned to the patient. The adsorber "PentraSorb® CRP" used for CRP apheresis is CE-certified. It is designated to the selective depletion of C-reactive protein from human blood.

CRISIS I is a prospective, multicenter, randomized controlled trial, to asses the impact of intensive blood pressure control on clinical outcome of acute ischemic stroke patients with successful recanalization after endovascular therapy.

Stroke is thought to cause disability immediately after stroke followed by a 3-to-6-month recovery period, after which disability levels are supposed to stabilize unless recurrent events occur. However, studies showed that post-stroke recovery is heterogeneous. While some stroke survivors quickly recover, others may show an accelerated accumulation of disability over time. The current prospective observational study will investigate trajectories of multidimensional functioning and self-rated health in the year after stroke. Particularly, the study aims to explore the relationship between trajectories of disability and self-rated health. Moreover, the study will focus on potential predictors of changes in disability and self-rated health, i.e., views on aging and psychological resilience. Patients will be recruited during their stay at the stroke unit and participate in a face-to-face interview and four follow-up telephone interviews in the post-stroke year.

This proposal is a prospective, single-center, dose-escalation safety, tolerability, feasibility and potential efficacy study of transcranial direct current stimulation (tDCS) in acute stroke patients with substantial salvageable penumbra due to a large vessel occlusion before and after endovascular therapy.

This is an open, pilot, dose-escalation study of glyceryl trinitrate (GTN, Nitroglycerin) administered by paramedics in the field within 2 hours of symptom onset to 45 severely hypertensive stroke patients. The primary objective of the study is to evaluate the feasibility, safety, and physiologic efficacy of field-initiated glyceryl trinitrate in achieving modest reduction of blood pressure. Patients with acute stroke will be identified in the field by paramedics who have received training in basic and advanced cardiac life support, stroke recognition, and specific procedures relevant to the proposed study. Physician-investigators will obtain informed consent for each subject for study entry after cellular phone contact with paramedics. Paramedics will initiate antihypertensive treatment by applying transdermal GTN patch in the first two dose-tiers, and administering a single sublingual GTN metered spray followed by application of the transdermal system in the last dose tier. The sites involved in the study will be emergency medical services rescue ambulances and 8 receiving Stroke Center hospitals in Orange County, California, USA.
