Filter by:The study is a prospective, multicenter, randomized, double-blind, placebo-controlled study evaluating the safety and efficacy of tirofiban in combination with intravenous thrombolytic therapy with alteplase in acute ischemic stroke
The study is a prospective, multi-center, single arm, feasibility study that will enroll a maximum of 36 subjects. The maximum enrollment is 10 subjects per site. A maximum of 6 investigational centers in Europe will participate. Enrollment is expected to take about 9 months, subject participation will last about 3 months.
What research question is being addressed? Can improve the prediction of adverse outcomes be improved for people following a stroke to optimise their treatment and care? How is it of relevance and importance to patients and public? Following a stroke, people are at a higher risk of developing certain conditions including heart failure, another stroke and atrial fibrillation, a type of irregular heart rhythm. In the proposed study, the investigators will look at factors which may increase a person's risk of such conditions following stroke. From this, the investigators will determine if risk scores for these conditions can be improved for people post-stroke. This could help doctors decide what treatments are best. Who would be eligible? All adults at participating hospitals who have had an ischaemic stroke (where the stroke is caused by loss of blood flow to the brain) or a transient ischaemic attack ('mini-stroke') confirmed by a stroke doctor. All patients will be asked to take part in the study, or their family members may be asked to provide advice on their behalf if the patient is unable to. Where is the study being conducted? At participating hospitals in England and Wales. What will the participants undergo? At the time of stroke, patients have a lot of information collected about their health, the investigators will copy information from patient's medical records about their health after they agree to take part in the study. Patients or their family members will also be asked to complete some additional brief questionnaires about their quality of life, wellbeing and fatigue. Some questionnaires such as for cognitive function are already collected for patients following a stroke, but where this information has not been collected, it will be collected for the study. The investigators will ask the patients if they can be contacted in 12-months to repeat the questionnaires and information collected about their health.
This project is intended to collect data using standard clinical tests and psychophysics to quantify the effect of visual cortical damage on the structure of the residual visual system, visual perception, spatial awareness, and brain function. The investigators will also assess the effect of intensive visual retraining on the residual visual system, processing of visual information and the use of such information in real-world situations following damage. This research is intended to improve our understanding of the consequences of permanent visual system damage in humans, of methods that can be used to reverse visual loss, and of brain mechanisms by which visual recovery is achieved.
A randomized, double blind, multicenter, multinational, placebo controlled, parallel group, single dose, adaptive phase II/III study. The study evaluates the efficacy and safety of a fixed dose of glenzocimab (1000 mg IV over 6 hrs including initial bolus of 15 minutes) on top of the best standard of care.
The SUMMIT MAX study is a prospective, randomized, controlled, interventional clinical trial to evaluate the safety and effectiveness of the Route 92 Medical MonoPoint® Reperfusion System with the Hi Point 88 and HiPoint 70 Reperfusion Catheters for aspiration thrombectomy in acute ischemic stroke patients.
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 aims to assess the incidence of atrial fibrillation (AF), documented using data recorded by an implantable Holter monitoring device (Reveal Linq, Medtronic) within 2 years after percutaneous closure of patent foramen ovale for cryptogenic stroke.
The main aim of the study is to investigate the prevalence and characteristics of ischemic stroke patients with atrial fibrillation and concurrent carotid atherosclerosis. Additionally, this study will investigate the effect of concurrent carotid atherosclerosis on the outcomes of recurrent stroke, myocardial infarction and death during follow-up
Sickle cell disease (SCD) is the most common genetic disease, affecting about 25 million people worldwide. Approximately 150,000 Nigerian children are born each year with sickle cell disease (SCD), making it the country with the largest burden of SCD in the world. Recent advancements in care for children with SCA have translated into improved survival of children in both high and low-resource settings. However, more complications of SCD are seen in those who survive to adulthood. Silent cerebral infarcts (SCI) and strokes are among the most devastating complications of SCD, affecting 40% and 10% of children, respectively. The overall goal of this study is to extend the Investigator's successful capacity-building effort in the assessment of neurological morbidity in children with SCD living in northern Nigeria (Kano) to young adults with SCD living in the same region. About 50% of all adults with SCD live in Nigeria. Despite the high prevalence of SCD in Africa, the neurological morbidity is not well characterized, limiting opportunities for primary and secondary stroke prevention strategies. At least 50% of young adults with sickle cell anemia (SCA), the most severe form of the disease, will have SCIs and an estimated 10% will have strokes, based on studies in high-resource settings. In high-resource settings, screening for abnormal transcranial Doppler (TCD) velocities in children with SCA, coupled with regular blood transfusion has resulted in a 92% reduction of relative risk for strokes. Despite this effective strategy, regular blood transfusion therapy does not seem sustainable in sub-Saharan Africa due to shortages and the risk of transfusion transmissible infections. Additionally, there is a lack of evidence-based stroke prevention strategies in young adults with SCA, either in the high-income or in low-resource settings. Based on the foregoing, the Investigators propose to determine the prevalence of neurological injury (overt stroke, transient ischemic attacks, and silent cerebral infarcts) in young adults at the transition age from 16-25 years. The Investigators will also, for the first time, assess conventional risk factors of stroke in the general population to determine whether a different prevention strategy is required to reduce the incidence of neurological injury in this high-risk population.
