Normobaric Hyperoxia Combined With Endovascular Therapy in Patients With Stroke Within 6 Hours of Onset:Longterm Outcome

Start date: April 1, 2021
Phase: N/A
Study type: Interventional

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.

Biomarkers of Independent Walking Post-Stroke

Start date: August 2021
Study type: Observational

Prediction of walking recovery after stroke can inform patient-centered care and support discharge planning. The accuracy of current prediction models is limited, however, due to small study designs and narrow predictors assessed. The investigators propose a comprehensive evaluation of a novel combination of biomarkers to improve prediction of walking recovery and guide rehabilitation efforts after stroke. These include acute structural brain network disruption (utilizing MRI); blood biomarker levels (e.g., brain-derived neurotrophic factor and vascular endothelial growth factor); and clinical assessments of strength and mobility. The overall study objectives are to assess protocol feasibility and investigate relationships between select biomarkers and walking recovery to provide strong justification for a larger study on predictors of independent walking after stroke. The proposed objectives will be pursued through the following specific aims: 1) Assess feasibility of a larger study and develop methods for telehealth data collection; 2) Establish baseline levels of biomarkers and average change over time; and 3) Elucidate relationships between baseline levels of biomarkers and walking gains across time in persons after stroke. A longitudinal, observational study design will be utilized for this study. Thirty-five persons with acute (≤3 days) stroke will be recruited from the local medical center. Select inclusion criteria include presence of new lower limb weakness and assistance for walking; select exclusion criteria include cerebellar stroke or other neurological disorders such as Parkinson's Disease. Subjects will undergo clinical evaluation within 3 days, 1, 4, 9, 12, and 26 weeks post-stroke. MRI scans will occur within 1 week and 12 weeks post-stroke, and blood draws at 72 hours, 1 week, and 12 weeks post-stroke. To assess feasibility the investigators will examine study processes, recruitment, resources, study management, and scientific assessment. To examine the role of acute clinical, neuroimaging, and physiological measures in predicting walking recovery, the investigators will examine relationships between these measures and walking outcome at 12-weeks post-stroke. The proposed research is expected to provide strong scientific support for future clinical trials designed to target therapies based on predicted functional potential. Such knowledge has the potential of enhancing mobility gains and patient independence following stroke.

Impact of COVID-19 Vaccines on Cerebrovascular Health

Start date: July 5, 2021
Study type: Observational

Safe and effective SARS-CoV-2 vaccines may reduce the transmission of and achieve population immunity against the COVID-19 pandemic, which accounted for more than 3.75million deaths worldwide. With World Health Organization's (WHO) effort on ensuring equitable access to COVID-19 vaccines, vaccination rate may increase in the near future. On the other hand, vaccination hesitancy has emerged as a major hindrance on the global vaccination campaigns in certain areas due to safety concerns, social factors, and public health policies. For instance, a recent survey conducted in Hong Kong showed a low vaccine acceptance rate of 37%. Long-term safety concerns and post-vaccination events relayed by the social media maybe reasons for vaccination hesitancy. Among which, cerebrovascular accidents (CVA) after vaccination were one of the most frequently reported post-vaccination events. These reports ranged from ischemic strokes in elderly patients with multiple cardiovascular co-morbidities, to hemorrhage strokes in otherwise "young-and-fit" adults. While many of these events were investigated by the COVID-19 immunization expert committee, an important premise to address the apprehension of CVA after vaccination is the provision of evidence-based information of the impact of COVID-19 vaccines on brain health. In this prospective, longitudinal, observational study, we aim to elucidate the relationship between COVID-19 vaccines and cerebrovascular health in healthy citizens in a population-based cohort.

Efficacy of Cerebrolysin Treatment as an add-on Therapy to Mechanical Thrombectomy in Acute Ischemic Stroke.

Start date: January 1, 2021
Phase: Phase 3
Study type: Interventional

This study is designed to determine the efficacy and safety of Cerebrolysin treatment as an add- on therapy to mechanical thrombectomy (MT) in reducing global disability in subjects with acute ischemic stroke (AIS). The investigators have planned a single centre, prospective, open-label, single-arm study with 12 months follow-up of 50 patients with moderate to severe AIS, with a small established infarct core and with good collateral circulation who achieve significant reperfusion following MT and who receive additional Cerebrolysin within 8 hours of stroke onset compared to 50 historical controls treated with MT alone - matched for age, clinical severity, occlusion location, baseline perfusion lesion volume, onset to reperfusion time and use of iv thrombolytic therapy (rt-PA). The primary outcome measure will be overall proportion of subjects receiving Cerebrolysin comparing to control group experiencing a favorable functional outcome (by modified Rankin Scale [mRS] 0-2) at 7 day, 30 days, 90 days and 12 months following stroke onset. The secondary objectives are to determine the efficacy of Cerebrolysin as compared to control group in reducing risk of symptomatic secondary hemorrhagic transformation, improving neurological outcome (NIHSS 0-2 at day 7, day 30 and 90); reducing mortality rates (over the 90-day and 12 months study period); and improving: activities of daily living (by Barthel Index; BI), health-related quality of life (as measured by the EQ-5D-5L) assessed at day 30, 90 and at 12 months. The other measures of efficacy in Cerebrolysin group will include: assessment of final stroke volume and penumbral salvage (measured by CT/CTP at 30 days) and its change compared to baseline volume, changes over time in language function (by the 15-item Boston Naming Test), hemispatial neglect (by line bisection test), global cognitive function (by The Montreal Cognitive Assessment) and depression (by Hamilton Depression Rating Scale) between day 30 and day 90 assessments). The patients will receive 30 ml of Cerebrolysin within 8h of AIS stroke onset and continue treatment once daily until day 21 (first cycle) and they will receive a second cycle of treatment (30 ml/d for 21 days given in the Outpatient Department or Neurorehabilitation Clinic) from day 69 to 90 (± 3 days). All the patients (including those from the control group) receive the same standardized rehabilitation program (including speech therapy, occupational and physical therapy) during hospitalization at Stroke Unit and at Neurorehabilitation Clinic until day 90 according to local procedures. Historical data will be obtained by retrospective clinical chart reviews of patients hospitalized in the study center between Jan.2018 and Dec.2020 and fulfilling the same clinical and radiological inclusion criteria in whom 12-month follow-up (including mRS, NIHSS, BI, EQ-5D-5L) could be obtained.
