Filter by:The VITATOPS study is a multi-center, randomized, double blind, placebo-controlled secondary stroke prevention trial to determine whether the addition of vitamin supplements (B12 500 ug, B6 25 mg, Folate 2 mg) to best medical/surgical management (including modification of risk factors) will reduce the combined incidence of recurrent vascular events (stroke, myocardial infarction) and vascular death in patients with recent stroke or transient ischemic attack (TIA). All patients presenting to one of the participating neurologists or general physicians within seven months of stroke (ischemic or hemorrhagic) or TIA (eye or brain) are eligible for this trial. Eligible patients will be randomized in a double-blind fashion to receive multi-vitamins or placebo, 1 tablet daily. The primary outcome event is the composite event "stroke, myocardial infarction, or death from any vascular cause", whichever occurs first. Our target is to recruit a total of 8,000 patients over the next two years with a median follow-up of 2.5 years. Recruitment to the trial began in November 1998 and is planned to continue until December 2005. We aim to complete final follow-up by the end of 2006. However, the Steering Committee will be flexible in dictating the need for ongoing recruitment and continuing follow-up, depending on the overall rate of the primary outcome event in the entire cohort at each interim analysis.
This study will determine the maximum safe dose of the experimental drug E-selectin that can be given to stroke patients. E-selectin causes white blood cells called lymphocytes to change so that they prevent clots from forming in the vessels that supply blood to the brain. The drug has been shown to be effective in animal models of stroke. This study will look at the safety of using this experimental drug in nasal instillation form in patients who have had a stroke or transient ischemic attack (TIA). Patients 45 years of age or older who have had a recent stroke or TIA (30 to 120 days before entering the study) due to a clot forming in a vessel that supplies blood to the brain may be eligible for this study. They must be taking at least one medication to prevent clots, such as coumadin, aspirin, ticlopidine, or others. Candidates will be screened with a physical and neurological examination, blood and urine tests, electrocardiogram (EKG), echocardiogram (ultrasound test of the heart), and magnetic resonance imaging (MRI) of the brain. Participants will be randomly assigned to receive E-selectin at a dose level of 5, 15, or 50 micrograms or a placebo (nasal drops with no active ingredient). They will instill a small, carefully premeasured amount (one dose) of fluid in their nose every other day for 10 days (total of 5 doses). This course of treatment will be repeated two times at 3-week intervals. Patients will be followed at 1 month and 3 months with a neurologic examination and blood and urine tests. They will be contacted by phone, fax, or email in between these two visits.
This study will determine if NXY-059 will improve recovery from an acute stroke. The study is designed to look at both overall recovery and recovery of motor function, for example muscle strengthen and coordination.
The purpose of this study is to determine if extracranial-intracranial bypass surgery when added to best medical therapy can reduce the subsequent risk of ipsilateral stroke in high-risk patients with recently symptomatic carotid occlusion and increased cerebral oxygen extraction fraction measured by positron emission tomography (PET).
This study will test the safety and effectiveness of a protein called E-selectin, given as a nasal spray, in preventing the formation of blood clots that can cause stroke. In animal studies, animals that received E-selectin in the nose on a regular schedule had almost no strokes compared with those that did not receive it. Patients over age 45 who have had a stroke or transient ischemic attack (TIA) within 1 to 4 months of this study may be eligible to participate. Candidates will be screened with a review of their past medical records and neurologic and medical evaluations that may include magnetic resonance imaging (MRI) of the brain, ultrasound or magnetic resonance angiography (a type of MRI) of the carotid arteries (arteries in the neck that supply blood to the brain), echocardiography (ultrasound test of the heart), electrocardiography (EKG) and blood tests. Participants will have a blood and urine test and will be assigned to one of four treatment groups. Patients in each group will spray a small amount of fluid into their nose according to the following schedule: 5 doses once every other day for 10-days, followed in 3 weeks by another 5 doses every other day for 10-days, followed in 3 weeks by a final series of 5 doses every other day for 10 days. The spray for patients in each group contains the following: - Group 1 - fluid with low dose of E-selectin - Group 2 - fluid with medium dose of E-selectin - Group 3 - fluid with high dose of E-selectin - Group 4 - fluid with no E-selectin Patients will be seen for follow-up visits at 1 month and 3 months after starting E-selectin therapy. The visits will include a neurologic examination and blood and urine tests. Patients will be contacted by phone, fax or e-mail in between the 1- and 3-month visits.
The purpose of this study is to learn more about stroke and obtain information that may serve as the basis for future investigations. It will 1) establish a registry of patients with cerebrovascular disease (stroke); 2) characterize the natural history of acute stroke and transient ischemic attacks (TIA)-an interruption of blood flow to the brain that causes stroke symptoms for a short period of time); and 3) evaluate the data to generate ideas for future studies. Patients 18 years of age or older with suspected acute stroke or TIA may be eligible for this study. Subjects will be recruited from patients who present with stroke at the emergency department of Suburban Hospital in Bethesda, Maryland. The study will gather data collected from diagnostic and laboratory tests the patient undergoes as part of standard medical care, including findings of medical and neurological examinations and other tests. In addition, studies will be done for research purposes only to gather data about stroke and TIA. These may include the following: - Blood and urine tests not more than 2 tablespoons of blood will be drawn for various tests. - Electrocardiogram (EKG) (heart tracing)-electrodes placed on the chest wall detect the heartbeat and heart rhythm. - Computed tomography (CT) scan of the head-specialized X-rays are used to obtain images of the brain. - Magnetic resonance imaging (MRI) of the brain-a strong magnetic field and radio waves are used to produce images that provide information about the brain tissue and blood vessels. - Transcranial Doppler (TCD)-sound waves are used to image the arteries of the brain and neck. - Echocardiogram-sound waves are used to image the heart and evaluate heart function. Patients may be asked to return to Suburban Hospital for follow-up testing in 1, 3, and/or 12 months, when some of these tests may be repeated to assess changes over time
