149 Clinical Trials for Various Conditions
To investigate whether MR-guided laser induced thermal therapy in patients diagnosed with focal lesional epilepsy using the Visualase Thermal Therapy System is both a feasible and safe minimally invasive technique for control of seizures in such patients.
The purpose of this study is to evaluate the efficacy, safety and tolerability of VX-765 in subjects with treatment-resistant partial epilepsy.
This long-term extension study will assess the safety, tolerability and efficacy of BGG492 as adjunctive treatment in patients with partial onset seizures.
To prospectively demonstrate the superior anxiolytic effect of high dose pregabalin (PGB) therapy (450 mg/day) compared to low dose PGB therapy (150 mg/day) in subjects with medically refractory partial epilepsy not fully controlled despite treatment with 1-2 concomitant antiepileptic drugs (AEDs).
This is an 18-week, double-blind, multicenter study with gradual conversion from previous antiepileptic therapy to eslicarbazepine acetate monotherapy in subjects with partial epilepsy.
Many patients with epilepsy have memory deficits in the setting of otherwise normal intelligence. Unfortunately, the treatment options for memory dysfunction in patients with epilepsy are limited. The investigators are conducting a study to evaluate the effects of memantine for the treatment of verbal memory dysfunction in subjects with localization-related seizures. The study involves randomization to memantine therapy or placebo, with cognitive testing and EEG pre- and post-treatment, as well as after an open-label memantine treatment phase. The primary aim of this study is to evaluate the efficacy of memantine for the treatment of verbal memory dysfunction in subjects with left temporal lobe epilepsy. The investigators expect that verbal memory task performance will improve in those taking memantine, but not in those taking a placebo. The investigators propose that the expected benefit of memantine is specific to verbal memory in subjects with left temporal lobe seizures, rather than representing an overall improvement in cognitive function. The investigators expect no improvement on other cognitive tasks in either the memantine or placebo groups. The investigators will evaluate whether subjects with left temporal lobe epilepsy and memory difficulties have self-reported improvement in memory while taking memantine. The investigators expect improvement of self-rated memory function on the Quality of Life in Epilepsy Patient Inventory (QOLIE-89) in the memantine group, but no change on this scale in the placebo group.
The purpose of this study is to determine the safety, tolerability, and efficacy of VX-765 in subjects with Treatment-resistant Partial Epilepsy
The purpose of this study is to determine the effects of fluoxetine on breathing mechanisms during seizures. Patients with partial epilepsy commonly have changes in their breathing mechanisms during seizures. These changes may increase the risk of serious side effects from seizures, including sudden unexplained death in epilepsy (SUDEP), which affects 2-10 per 1000 patients with epilepsy each year. Fluoxetine (Prozac) may help to stimulate breathing through its actions in the brain and has been shown to improve breathing changes seen with seizures in certain animals. Fluoxetine is in a class of medications called selective serotonin reuptake inhibitors (SSRIs). It works by increasing the amount of serotonin, a natural substance in the brain, at synapses, the junctions at which nerve cells in the brain communicate. Fluoxetine is currently approved by the United States Food and Drug Administration (FDA) for the treatment of patients with Major Depressive Disorder, Obsessive Compulsive Disorder, Bulimia Nervosa, Panic Disorder and Premenstrual Dysphoric Disorder.
The purpose of the Phase II clinical trial will be to see if a botanical extract from the plant Passiflora incarnata can improve seizure control and reduce anxiety in patients diagnosed with partial epilepsy. The investigators will randomize approximately 25 participants with partial epilepsy for this placebo controlled, double blind, and crossover study. All patients will be scheduled for 10 clinic visits and four telephone visits during the 32-week period of the trial. After enrollment into the study, all participants will begin a 9-week observation phase, which serves as an individual baseline control. After 9 weeks participants will be randomized to receive either study drug or placebo for an 11 week study period. After completion of the 11 week study period, patients will crossover to the other study drug/placebo arm for another 11 weeks. Epilepsy participants will continue taking their anti-epileptic medication as currently prescribed. The investigators will find participants through the OHSU clinics, by notifying local neurologists, anthroposophical and naturopathic practices, and by advertising the study via the local chapter of the American Epilepsy Society. Routine blood tests, physical examinations and tests to monitor heart, brain and muscle activities will screen for any adverse effects. The primary outcome measure will be seizure frequency through seizure diaries. Attention and performance tests, neurological and quality of life questionnaires will be completed to assess the secondary outcome measures of anxiety, cognitive function and quality of life.

To evaluate the long-term safety of pregabalin in refractory partial epilepsy.
This study will examine the possible structural and functional abnormalities in patients with an inherited form of epilepsy. It will use magnetic resonance imaging (MRI). Uncontrolled epilepsy is a serious neurological problem with major harmful medical, social, and psychological effects, as well as greater mortality compared with the general population. The cost per year in the United States is at least $12.5 billion. There have been advances in diagnosing the disease, but the cause cannot be determined in many cases. Recently, several seizure syndromes found in families have been described. One syndrome of particular interest involves the lateral temporal lobe of the brain and often includes auditory features. Patients with that kind of syndrome may hear monotonous unformed sounds, but sometimes they may hear complex sounds, such as a song. Patients are eligible for this study if they have a specific form of familial epilepsy that is being studied at Columbia University in New York. Family members without seizures are eligible as well. All the patients in the study will be evaluated at Columbia before participating. Healthy volunteers aged 18 to 55 also may be eligible for this study. Participants will undergo a medical history and physical examination. During the study, they may have three or four sessions of MRI. During the MRI, patients will lie still on a table that can slide in and out of a metal cylinder surrounded by a strong magnetic field. Scanning time varies from 20 minutes to 3 hours, with most scans lasting between 45 and 90 minutes. Patients may be asked to lie still for up to 60 minutes at a time. As the scanner takes pictures, there will be loud knocking noises, and the patients will wear earplugs to muffle the sound. Patients will be able to communicate with the MRI staff at all times during the scan and may ask to be moved out of the machine at any time. Some scans may be done in a 3 Tesla scanner. It is the latest advance in MRI, with a stronger magnetic field than in the more common 1.5 Tesla scanner. Functional MRI (fMRI) is done while patients are performing tasks, such as moving a limb or speaking. Patients will have an opportunity to practice such tasks before entering the scanner. The fMRI will take about 1 hour. ...
Transcranial Magnetic Stimulation (TMS) is a non-invasive technique that can be used to stimulate brain activity and gather information about brain function. It is very useful when studying the areas of the brain related to motor activity (motor cortex, corticospinal tract, and corpus callosum). Epilepsy is a condition associated with seizures as a result of an over excitable cerebral cortex. Despite the introduction of several new antiepileptic medications, less than half of the patients diagnosed with partial epilepsy are well controlled. However, studies have shown that non-invasive stimulation of the brain can decrease the excitability of the cerebral cortex. Researchers are interested in the potential therapeutic effects of TMS on patients with epilepsy that have responded poorly to standard medication. This study will use TMS to decrease the excitability of the areas of the brain responsible for seizures.
Primary objective: To evaluate the safety and tolerability of cenobamate in pediatric subjects 2-17 years of age with partial-onset (focal) seizures
The primary objective of this study is to assess the pharmacokinetics of cenobamate (YKP3089) in pediatric subjects with partial-onset (focal) seizures following single and multiple-dosing.
This is a multicenter, open label study to assess the safety and pharmacokinetics of YKP3089 as adjunctive therapy in subjects with partial onset seizures. Initially, subjects taking phenytoin or phenobarbital will be enrolled followed by additional subjects taking anti-epileptic drugs (AED) other than phenytoin and phenobarbital to further investigate long-term safety.
This is a multicenter, double-blind, randomized, placebo-controlled dose response study, with an 8-week prospective baseline and an 18 week double-blind treatment period (including a 6-week titration phase and 12 week maintenance phase), followed by a 3-week blinded study drug taper period (for subjects leaving the study) or a 2-week blinded conversion period (for subjects who will participate in the open-label extension). The primary objective of this study is to determine the effective dose range of YKP3089 as adjunctive therapy for the treatment of partial seizures. The trial will also evaluate the safety and tolerability of YKP3089 in the partial epilepsy population.
This study is to evaluate the efficacy of YKP3089 in reducing seizure frequency when compared to baseline in subjects with partial onset seizures not fully controlled despite their treatment with 1 to 3 concomitant anti-epileptic drugs. Also to evaluate the safety and tolerability of YKP3089.
Sleepiness and fatigue are the most common complaints of people with epilepsy and can have a negative impact on quality of life. Though unproven, these problems are often blamed on anti-seizure medications. The purpose of this study is to investigate the impact of the anti-seizure medication Lacosamide (Vimpat®) on sleep and wakefulness in adults with focal (partial onset) seizures. Focal epilepsy, also called partial epilepsy, is a disorder characterized by seizures arising from a localized network of neurons in the brain. Focal seizures usually begin a sensation or involuntary movement of a part of the body, an unusual feeling, or a disturbance in hearing, smell, vision, or consciousness. The study is open to adults 18 and older with focal seizures. Participation involves a physical exam, sleep testing at the Sleep Center, blood tests, completion of study questionnaires/diaries, and a random assignment to either take the study drug or placebo (often called a "look alike" or "sugar pill") for 5 to 8 weeks. There are 5 study visits. Participants will receive compensation for time spent in the study.
