Benzodiazepine Refractory Status Epilepticus

The primary objective is to determine the most effective and/or the least effective treatment of benzodiazepine-refractory status epilepticus (SE) among patients older than 2 years. There are three active treatment arms being compared: fosphenytoin (FOS),levetiracetam (LEV), and valproic acid (VPA). The second objective is comparison of three drugs with respect to secondary outcomes. The final objective is to ensure that the trial is informative for treatment of established SE in children by describing the effectiveness, safety, and rate of adverse reactions of these drugs in children.

Brain and Spinal Tumors

The Tumor Related Epilepsy research study (16-N-0041) will evaluate and offer surgery to people with tumor-related epilepsy, and explore how surgery affects seizures. Some people who have brain tumors have seizures related to the tumor, which is a condition called tumor-related epilepsy. The standard treatment for people with brain tumors is surgery to remove as much of the tumor as possible without causing additional neurological problems. Researchers think this method of treatment may improve the outcome for people with brain tumors because it may completely relieve or greatly reduce the number of seizures they experience.

The Evaluation and Treatment of Neurosurgical Disorders research study (03-N-0164) will evaluate people with a variety of neurosurgical disorders in order to provide standard expert care and physician training. In the study, doctors will assess and treat people who have disorders of the brain, spinal cord, peripheral nerves, or pituitary gland that may or may not require surgery. This study will not test new treatments. Participants will receive standard care.

Dystonia

The Deep Brain Stimulation Surgery for Movement Disorders study (11-N-0211) uses deep brain stimulation (DBS) to treat Parkinson’s disease, dystonia, and essential tremor. DBS is an approved surgical procedure for these neurological conditions which do not respond well to other treatments. The objective of this research is to study normal human biology and disease pathogenesis (natural history) and to collect physiology and efficacy data related to DBS therapy and motor and cognitive function in the study population.

Background: - It is hard for people with arm spasticity and focal hand dystonia to control their arm and hand muscles. They are often treated with botulinum toxin (BoNT) injections. Electromyography with electrical stimulation (e-stim) and ultrasound are used to find muscles for BoNT injection. Researchers want to learn which method is faster and more comfortable. Objective: - To compare 2 ways of finding muscles for BoNT injection for the treatment of focal hand dystonia and upper limb spasticity. Eligibility: - Adults 18 and older with focal hand dystonia or arm spasticity who have been getting onabotulinumtoxin-A injections in protocol 85-N-0195. Design: - Participants will be screened with medical history and physical exam. - Participants will push or pull on a device that measures arm strength. They will have a neurologic exam. Women will have a pregnancy test. - Participants will have a BoNT injection using either e-stim or ultrasound. - For e-stim, sticky pads will be placed on the arm. A needle will be placed in the muscle. A small electric shock will be given through the needle. Then the injection will be given. - For ultrasound, a probe will be moved across the skin. A screen will show an image of the muscles. Then the injection will be given. - Participants will have a second injection 3 months later. They will have the method that was not used for their first injection. - After each session, participants will rate their experience. - Participants will have follow-up visits 1 month after each injection. They will be examined and asked about their response to treatment. Arm strength will be measured.

High Blood Pressure

ENCHANTED is an independent, investigator initiated, international collaborative, quasi-factorial randomised controlled trial involving a package of 2 linked comparative randomised treatment arms, which aims to address 4 key questions in patients eligible for thrombolysis in the acute phase of ischaemic stroke. (1) Does low-dose (0.6 mg/kg) intravenous (i.v.) recombinant tissue plasminogen activator (rtPA) provide equivalent benefits compared to standard-dose (0.9 mg/kg) rtPA? (2) Does intensive blood pressure (BP) lowering (130-140 mmHg systolic target) improve outcomes compared to the current guideline recommended level of BP control (180 mmHg systolic target)? (3) Does low-dose (0.6 mg/kg) intravenous (i.v.) recombinant tissue plasminogen activator (rtPA) reduce the risk of symptomatic intracerebral haemorrhage (sICH)? (4) Does the addition of intensive BP lowering to thrombolysis with rtPA reduce the risk of any intracerebral haemorrhage (ICH)? The rtPA dose arm of the study addressing questions (1) and (3) concluded with a publication of the results in May 2016. The BP intensity arm of the study is ongoing.

Ischemic Stroke

The purpose of the ARCADIA trial is to compare two different blood-thinning drugs—apixaban and aspirin—to determine which is better for preventing recurrent stroke in people who have cryptogenic stroke (stroke of unknown cause) and atrial cardiopathy (abnormal changes in the atrial tissue and function of the heart).

NINDS Announces Early Study Closure of SURE-PD3 Trial

The National Institute of Neurological Disorders and Stroke (NINDS) has accepted the Data and Safety Monitoring Board’s (DSMB) recommendation to stop SURE-PD3, the Study of URate Elevation in Parkinson’s disease (PD), after an interim analysis showed it would be unlikely to demonstrate benefit of long-term treatment with inosine in people with PD. The trial was testing whether a treatment that raises blood levels of the natural antioxidant urate for two years slows the rate of worsening in PD. The randomized, placebo-controlled, double-blinded trial, funded by the NINDS, was conducted nationwide at 57 clinical sites of the Parkinson Study Group (PSG). It was led by investigators at Massachusetts General Hospital (MGH) and the University of Rochester, with support from the Michael J. Fox Foundation.  

After two thirds of the patient data were collected, the study’s independent DSMB reviewed an unblinded analysis of the primary outcome, measurement of disease progression. Study statisticians determined that even if the trial were continued so that all participants were treated for the full two years, it would unlikely show benefit of inosine by the primary measurement.  Accordingly, the DSMB recommended that the study be ended early. The DSMB did not note any significant safety concerns though high levels of urate are known to cause gout. 

Site investigators and coordinators have informed SURE-PD3 participants of the study closure. Patients will be invited to continue as volunteers in the NINDS-funded AT-HOME-PD study which focuses on how telehealth assessments via video, smartphone tracking, and computer-based questionnaires can improve the way PD trials are performed.

The SURE-PD3 trial will be closed out over the next six months, and final results are expected by the end of 2019.  The NINDS is very appreciative of the efforts of patients, care givers and investigators in this important clinical trial.  

The purpose of this trial (17-N-0076) is to study the effect of N-acetylcysteine (NAC) on brain chemistry in people with Parkinson’s disease (PD). NAC is a drug approved by the U.S. Food and Drug Administration to treat acetaminophen (Tylenol) overdose and is also available as a dietary supplement.  Many symptoms of PD are caused by the loss of brain cells that produce a chemical called dopamine.  Some research suggests that these cells are damaged by the breakdown of dopamine due to a process called oxidation.  NAC can act as an antioxidant and may protect brain cells that control movement.  In this study researchers will determine if NAC can decrease the oxidation of dopamine in people with PD.

The study will take place at the NIH Clinical Center, in Bethesda, MD.  Thirty five people with PD will be enrolled after an initial screening visit to determine eligibility.  Eligible participants will be admitted to the NIH Clinical Center for 4 to 8 days.  Participants will take a total of 5 doses of NAC orally and will undergo 2 spinal taps (lumbar punctures)—the first will occur before starting NAC, and the second will occur after taking NAC for 2 days.

Participants will receive compensation. NIH will provide travel to and from the NIH Clinical Center within the U.S. for the inpatient visit.  NIH will also provide travel and local accommodations for a medical escort if the study researchers determine it is necessary for safety.

Information gained from this study will help researchers learn more about the effect of NAC on brain chemistry, which may lead to better treatments for PD.

Stroke

The purpose of this study is to clarify efficacy and safety of MRI-based intravenous thrombolysis with alteplase for patients with acute wake-up ischemic stroke and those having acute ischemic stroke with unknown time of symptom onset.

Traumatic Brain Injury

Transforming Research and Clinical Knowledge in Traumatic Brain Injury (TRACK-TBI) is a large, multi-center study that aims to improve both the classification methods for diagnosis of TBI and the evaluation of patient outcomes and clinical practices in order to improve the design of clinical trials.

The purpose of the Pediatric Autologous Bone Marrow Mononuclear Cells for Severe Traumatic Brain Injury (TBI) study is to determine if bone marrow mononuclear (or white blood) cells (BMMNCs) can improve brain structure and neurocognitive or functional outcomes in children with severe TBI. BMMNCs are made up of a mixture of cells, including stem cells. Stem cells are cells that have the potential to develop into some or many different cell types in the body.
