The Role of Hyperoxia in Acute Ischemic Stroke

Start date: June 1, 2019
Phase: N/A
Study type: Interventional

This study is being conducted to evaluate the potential therapeutic role of hyperoxia when applied in the immediate ischemic period following a stroke in the controlled Emergency Department setting. The study will evaluate the effects of hyperoxia in stroke patients on the production of markers of free radical damage and inflammatory markers associated with hyperoxic lung injury.

NCT ID: NCT03897478 Not yet recruiting - Stroke Clinical Trials

Biomarkers of Acute Stroke in Clinic

Start date: April 1, 2019
Study type: Observational

The proposed study will investigate the clinical use of the ISCDX test that may differentiate between diverse stroke etiologies as listed below: Aim 1: Differentiate between cardioembolic and large artery atherosclerotic ischemic strokes, when hemorrhagic stroke is ruled out, as defined by TOAST classification of subtypes of acute ischemic stroke. Aim 2: In cases of ischemic strokes of unknown or "cryptogenic" etiology, determine the ability of biomarker blood tests to predict etiology between cardioembolic and large artery atherosclerotic.

NCT ID: NCT03897153 Recruiting - Stroke, Acute Clinical Trials

Evaluation of the SONAS® Ultrasound Device for the Assessment of Bilateral Cerebral Perfusion in Subjects With Acute Stroke

Start date: February 12, 2019
Phase: N/A
Study type: Interventional

The purpose of this clinical investigation is to determine the safety and feasibility of detecting acoustic signals related to blood supply in subjects with acute large vessel occlusion (LVO) stroke by using the SONAS® device.

NCT ID: NCT03889249 Not yet recruiting - Stroke, Acute Clinical Trials

Alteplase Compared to Tenecteplase in Patients With Acute Ischemic Stroke

Start date: June 1, 2019
Phase: Phase 3
Study type: Interventional

The proposed trial is a pragmatic, registry based, prospective, randomized (1:1) controlled, open-label parallel group clinical trial with blinded endpoint assessment of 1600 patients to test if intravenous tenecteplase (0.25 mg/kg body weight, max dose 25 mg) is non-inferior to intravenous alteplase (0.9 mg/kg body weight) in patients with acute ischemic stroke otherwise eligible for intravenous thrombolysis as per standard care. All patients will have standard of care medical management on an acute stroke unit. There are no additional trial specific management recommendations. Patients will be followed for approximately 90-120 days.

NCT ID: NCT03888209 Recruiting - Stroke, Acute Clinical Trials

Transcranial Direct Current Stimulation (tDCS) Improves Functional Outcomes in Acute Stroke Patients

Start date: March 31, 2019
Phase: N/A
Study type: Interventional

Acute stroke patient will undergo one month (20 sessions) of physical therapy and anodal tDCS. Patients will undergo functional outcomes measured at 48h post onset, 7,14,21,28 days, 3 and 6 months and one year post onset.

NCT ID: NCT03885674 Recruiting - Stroke Clinical Trials

Improving Medication Self-Administration and Health After Brain Injury

Start date: July 2016
Phase: N/A
Study type: Interventional

The purpose of this research study is to assess medication self-administration (MSA) and the impact of three different interventions on improving medication adherence. The findings for this study may help develop evidence-based reminder protocols to reduce medication self-administration errors after brain injury.

NCT ID: NCT03876119 Recruiting - Stroke, Acute Clinical Trials

Intraarterial Alteplase Versus Placebo After Mechanical Thrombectomy

Start date: December 5, 2018
Phase: Phase 2
Study type: Interventional

Multicenter, randomized, placebo-controlled, double blind, phase 2b trial of acute stroke patients treated with mechanical thrombectomy (MT), in which two therapies are compared: rt-PA or placebo. Allocation at each center will account for 1 stratum: use of alteplase (yes vs. no) before MT. Subjects will be followed up to 90 days post-randomization.

NCT ID: NCT03854500 Not yet recruiting - Ischemic Stroke Clinical Trials

The Norwegian Tenecteplase Stroke Trial 2

Start date: March 1, 2019
Phase: Phase 3
Study type: Interventional

Background: Alteplase is the only approved acute drug treatment in ischemic stroke and aims at dissolving arterial clots causing cerebral ischemia. The overall benefit of alteplase is substantial. However, there is considerable room for improvement as 2/3 of patients with large clots may not achieve reopening of the vessel and up to 40% of the patients remain severely disabled or die. Tenecteplase, a modified tissue plasminogen activator, has been shown to be a more efficient and safer thrombolytic drug than alteplase in pre-clinical studies. Tenecteplase has replaced alteplase as thrombolytic treatment in myocardial infarction and may also be the drug of choice in ischemic stroke. Tenecteplase and alteplase had a similar safety profile in the NOR-TEST trial and there were no differences in efficacy between the two treatment groups. However, a majority of patients had mild stroke which may be associated with a natural favorable prognosis. In spite of these neutral results, tenecteplase has the potential to replace alteplase as the drug of choice, based on a better pharmacological profile and a simpler practical administration. There is, however, need for a higher number of patients to prove the efficacy and safety of tenecteplase. Hypothesis: Tenecteplase 0.4 mg/kg has superior efficacy and similar safety profile compared with alteplase 0.9 mg/kg.

NCT ID: NCT03843008 Not yet recruiting - Ischemic Stroke Clinical Trials

Melatonin in Acute Stroke

Start date: April 2019
Phase: N/A
Study type: Interventional

This study will measure Interleukin 6 (IL-6), a well-documented inflammatory biomarker that is increased in the acute phase of stroke, and to compare its levels after the administration of melatonin - a well-documented anti-inflammatory and anti-oxidant - that regulates circadian rhythm, which helps promote sleep.

Effects of Neuromuscular Electrical Stimulation in Muscle Architecture and Functionality of Patients After Acute Stroke

Start date: March 30, 2019
Phase: N/A
Study type: Interventional

Introduction: Stroke is a sudden illness, responsible for important neurological and cognitive sequelae that can result in functional limitations and dependence. It is the leading cause of neurological impairment in young adults and resting-related muscle loss is one of the major factors involved. Early rehabilitation is essential for these patients and neuromuscular electrical stimulation (NMES) has been identified as an intervention alternative due to its known effects on the prevention of muscle loss in patients with various pathologies. Objective: To evaluate the effects of NMES associated with conventional physiotherapy compared to conventional physiotherapy on muscle thickness and functionality of patients with acute stroke. Methodology: This is a randomized clinical trial, which will be performed at the Emergency and Unit Unit of the Stroke of the Hospital de Clínicas of Porto Alegre (HCPA). Patients with acute stroke, with up to 72 hours of hospital admission, who present with lower limb force deficit due to the current stroke will be included. Patients will be randomized into two groups: intervention group, who will receive the application of NMES associated with conventional physiotherapy and control group, who will receive the conventional physiotherapy of the HCPA. NMES training will be applied once a day (30 minutes of application per session with an increase of five minutes each week and gradual reduction in OFF time), five days a week until hospital discharge or up to a maximum of three weeks. The following outcomes will be assessed before and after the intervention: quadriceps and tibial thickness and quality of the quadriceps and tibialis anterior, muscle strength, stroke severity, gait, functionality and disability.
