  • BCI-FES Therapy for Stroke Rehabilitation

    open to eligible people ages 18-80

    There are over 7 million stroke survivors in the US alone, with approximately 795,000 new cases annually. Despite the best available physiotherapy, 30-60% of stroke survivors remain affected by difficulty walking, with foot weakness often being the main cause. Given that post-stroke gait impairments remain poorly addressed, new methods that can provide lasting improvements are necessary. Brain-computer interface (BCI) technology may be one such novel approach. BCI technology enables "direct brain control" of external devices such as assistive devices and prostheses by translating brain waves into control signals. When BCI systems are integrated with functional electrical stimulation (FES) systems, they can be used to deliver a novel physical therapy to improve movement after stroke. BCI-FES systems are hypothesized to stimulate recovery after stroke beyond that of conventional physical therapy.

  • Multi-arm Optimization of Stroke Thrombolysis

    open to eligible people ages 18 years and up

    The primary efficacy objective of the MOST trial is to determine if argatroban (100µg/kg bolus followed by 3µg/kg per minute for 12 hours) or eptifibatide (135µg/kg bolus followed by 0.75µg/kg/min infusion for two hours) results in improved 90-day modified Rankin scores (mRS) as compared with placebo in acute ischemic stroke (AIS) patients treated with 0.9mg/kg IV rt-PA within three hours of symptom onset. Patients may also receive endovascular thrombectomy (ET) per usual care. Time of onset is defined as the last time the patient was last known to be well.

  • NOninVasive Intracranial prEssure From Transcranial doppLer Ultrasound Development of a Comprehensive Database of Multimodality Monitoring Signals for Brain-Injured Patients

    open to eligible people ages 18 years and up

    This is an observational study in neurocritical care units at University of California San Francisco Medical Center (UCSFMC), Zuckerberg San Francisco General Hospital (ZSFGH), and Duke University Medical Center. In this study, the investigators will primarily use the monitor mode of the Transcranial Doppler (TCD, non-invasive FDA approved device) to record cerebral blood flow velocity (CBFV) signals from the Middle Cerebral Artery and Internal Carotid Artery. TCD data and intracranial pressure (ICP) data will be collected in the following four scenarios. Each recording is up to 60 minutes in length. Multimodality high-resolution physiological signals will be collected from brain injured patients: traumatic brain injury, subarachnoid and intracerebral hemorrhage, liver failure, and ischemic stroke. This is not a hypothesis-driven study but rather a signal database development project with a goal to collect multimodality brain monitoring data to support development and validation of algorithms that will be useful for future brain monitoring devices. In particular, the collected data will be used to support: Development and validation of noninvasive intracranial pressure (nICP) algorithms. Development and validation of continuous monitoring of neurovascular coupling state for brain injury patients Development and validation of noninvasive approaches of detecting elevated ICP state. Development and validation of approaches to determine most likely causes of ICP elevation. Development and validation of approaches to detect acute cerebral hemodynamic response to various neurovascular procedures.

  • Reducing Intracranial atheroSclErosis With Repatha

    open to eligible people ages 18-99

    The purpose of this study will be to understand the underlying mechanism by which PCSK9 inhibition reduces the rate of ischemic stroke seen in the pivotal studies that led to its FDA approval for ASCVD such as ischemic stroke. Those trials (FOURIER and ODYSSEY) enrolled almost 50,000 patients and showed that PCSK9 inhibition therapy is safe and effective. The investigators hypothesize that PCSK9 inhibition lowers the rate of stroke by reducing atherosclerotic plaque, which would be particularly beneficial for patients with intracranial atherosclerosis, who have the highest rate of recurrent stroke of any stroke mechanism.

  • SEACOAST 1- SEdAtion With COllAteral Support in Endovascular Therapy for Acute Ischemic Stroke

    open to eligible people ages 18-85

    SEACOAST 1 is a prospective, randomized, blinded endpoint trial comparing collateral vigor and clinical outcomes, with different forms of GA in patients with acute ischemic stroke due to anterior circulation large vessel occlusion (LVO) undergoing mechanical thrombectomy. The study compares GA with normocarbia (GAN) versus GA with mild hypercarbia (GAH), with a primary outcome of collateral robustness at measured at catheter angiography and clinical efficacy as secondary outcome. It is anticipated that the SEACOAST 1 will be followed by a larger, pivotal trial, SEACOAST 2, with primary clinical endpoints, in which the best method of GA identified in SEACOAST 1 is compared with the alternative strategy of anesthesia care (MAC) with minimal or no sedation. The current study focuses uppn SEACOAST 1, which is to be conducted in University of California, Los Angeles Ronald Reagan Medical Center and Santa Monica Medical Center. All acute stroke patients who arrive to one of these two stroke centers and are deemed eligible for thrombectomy will be considered for the proposed study. Physician-investigators will determine study eligibility. Informed consent to participate in the study will be obtained from legally authorized representatives or competent patients. For non-competent patients without on-scene legally authorize representatives, the consent process will utilize enrollment in emergency circumstances with exemption of informed consent (EFIC).

  • Sleep for Stroke Management and Recovery Trial

    open to eligible people ages 18 years and up

    The purpose of this study is to determine whether treatment of obstructive sleep apnea (OSA) with positive airway pressure starting shortly after acute ischemic stroke or high risk TIA (1) reduces recurrent stroke, acute coronary syndrome, and all-cause mortality 6 months after the event, and (2) improves stroke outcomes at 3 months in patients who experienced an ischemic stroke.

  • Transcranial Direct Current Stimulation as a Neuroprotection in Acute Stroke Before and After Thrombectomy

    open to eligible people ages 18 years and up

    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.

  • Transcranial Direct Current Stimulation for Post-stroke Motor Recovery

    open to eligible people ages 18-80

    This research study is to find out if brain stimulation at different dosage level combined with an efficacy-proven rehabilitation therapy can improve arm function. The stimulation technique is called transcranial direct current stimulation (tDCS). The treatment uses direct currents to stimulate specific parts of the brain affected by stroke. The adjunctive rehabilitation therapy is called "modified Constraint-Induced Movement Therapy" (mCIMT). During this therapy the subject will wear a mitt on the hand of the arm that was not affected by a stroke and force to use the weak arm. The study will test 3 different doses of brain stimulation in combination with mCIMT to find out the most promising one.

  • Intravenous N-Acetylcysteine for the Treatment of Acute Ischemic Stroke

    Sorry, not yet accepting patients

    Stroke is a major cause of death and long-term disability in the developed world. While t-PA and mechanical thrombectomy have been shown to decrease disability in properly selected patients, many patients are left with lifelong symptoms. There are currently limited options available for patients who are not candidates for treatment with t-PA and/or mechanical thrombectomy. N-Acetylcysteine (NAC) is an FDA approved antioxidant and anti-inflammatory agent that has been used safely for many years in the treatment of acetaminophen overdose. In studies, the oral form has been shown to improve outcomes in acute ischemic stroke and has been shown to decrease the effects of ischemic brain injury in animal models. In a small human trial, it improved outcomes in patients suffering from mild traumatic brain injury (TBI). The intravenous formulation has a long safety record. It is not FDA approved for treating stroke but was reviewed by the FDA and was given an FDA IND for this study. The investigators propose a prospective randomized, double-blind, placebo-controlled study to evaluate the efficacy of administering intravenous N-acetylcysteine to patients with acute ischemic stroke. Eligible subjects will receive a commercially available form of intravenous NAC (Acetadote®) through for the first 21 hours following their enrollment. Patients enrolled who receive t-PA for thrombolysis will have their intravenous NAC infusion delayed for 24 hours after the completion of their t-PA infusion. Patients undergoing thrombectomy will be excluded from enrollment. Subjects will be evaluated by emergency department and/or division of neurology physicians at the time of enrollment, during their hospitalization, as well as 30 days and 90 days after enrollment. At each visit, subjects will be assessed for functional status and quality of life. This study is designed to compare the efficacy of intravenous N-acetylcysteine compared to normal treatment in patients with acute ischemic stroke.

  • Rate of Atrial Fibrillation Through 12 Months in Patients With Recent Ischemic Stroke of Presumed Known Origin

    Sorry, in progress, not accepting new patients

    The purpose of the Stroke AF study is to compare the incidence of atrial fibrillation (AF) through 12 months between continuous cardiac rhythm monitoring with the Reveal LINQ™ Insertable Cardiac Monitor (ICM) (continuous monitoring arm) and standard of care (SoC) medical treatment (control arm) in subjects with a recent ischemic stroke of presumed known origin.

  • Zero Degree Head Positioning in Hyperacute Large Artery Ischemic Stroke

    Sorry, not currently recruiting here

    Placing the head of bed (HOB) at 0-degrees has been shown in small studies to improve blood flow to the brain in patients with ischemic stroke caused by large artery occlusions, thereby reducing stroke symptom worsening. This simple yet potentially impactful intervention has yet to be tested in a large clinical trial in hyperacute large artery ischemic stroke patients, but may provide nurses with a powerful contribution to acute stroke care that is capable of preventing worsening of stroke symptoms and promoting stabilization. Because stroke is the leading cause of preventable long-term disability in adults, this study may show that simple methods such as 0-degree HOB positioning should be considered one of the very first actions taken in the emergent management of acute ischemic stroke patients.
