Filter by: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.
The specific aim is to determine if there are patterns of temperature differences in the abdominal and back regions of individuals with partial/focal onset epilepsy as compared to a non-epileptic control group. The hypothesis is that individuals with partial/focal onset epilepsy will have colder recorded temperatures in the abdominal area than individuals in a matched control group.
Background: - The brain chemical serotonin helps nerve cells communicate. Previous research suggests that serotonin activity may be lower in brain areas where seizures start, and that increasing activity at the serotonin receptor site on nerve cells may help prevent seizures. Researchers are interested in determining whether the experimental medication PRX-00023, which increases the activity of serotonin receptors, can reduce seizure frequency in people whose seizures are not well-controlled on antiseizure medication. PRX-00023 has not previously been studied in people with epilepsy and has not previously been given to people taking antiseizure medication at the same time. Objectives: - To evaluate the effectiveness of PRX-00023 in reducing the frequency of epileptic seizures that start from only one part of the brain. Eligibility: - Individuals between 18 and 65 years of age who have frequent epileptic seizures even after trying at least two different standard anti-seizure medications (either at the same time or one after the other). Design: - The study requires 9 outpatient visits to the NIH Clinical Center over a 34-week period. Individuals who choose to participate in additional studies may be an inpatient during some of these visits. - Participants will be screened with a medical history and physical examination, blood and urine samples, ECG, EEG, neuropsychological studies, imaging studies, including PET and MRI scans - Participants will have a 6-week observation and evaluation period before starting the study medication. Participants who have at least four seizures during this period will be eligible for the treatment portion of the study. - All participants will receive either PRX-00023 or a placebo pill twice daily for 12 weeks, and will have regular clinic visits with blood samples and imaging studies. - After the 12-week period, participants will have a 2- to 3-week washout period without any study medication. - Participants will then have another study medication period, and will receive the opposite pill (PRX-00023 or placebo) from the one taken in the first treatment phase. Participants will continue to have regular clinic visits with blood samples, ECG, EEG and neuropsychologicalstudies. - One month after the end of the second study medication phase, participants will have a followup evaluation with a physical examination, blood tests, ECG, EEG, mood and neuropsychological tests. Outcome measures: The primary outcome measure for drug efficacy will be: Mean difference in seizure frequency comparing the active and placebo periods. Secondary outcome measures for efficacy will be: Proportion of patients with greater than or equal to 50% lower seizure rate on PRX-00023 than placebo Hamilton Depression and Anxiety Rating scales Performance on mood and neuropsychological testing scales
Background: - Drug resistant epilepsy is the term used to describe epilepsy that cannot be controlled by medication. Many people whose seizures do not respond to medication will respond to surgical treatment, relieving seizures completely or almost completely in one-half to two-thirds of patients who qualify for surgery. The tests and surgery performed as part of this treatment are not experimental, but researchers are interested in using the data collected as part of routine standard epilepsy care to better understand epilepsy and its treatment. Objectives: - To use surgery as a treatment for drug resistant epilepsy in children and adults. Eligibility: - Children and adults at least 8 years of age who have simple or complex partial seizures (seizures that come from one area of the brain) that have not responded to medication, and who are willing to have brain surgery to treat their medically intractable epilepsy. Design: - Participants will be screened with a medical history, physical examination, and neurological examination. Imaging studies, including magnetic resonance imaging and computer-assisted tomography (CT), may also be conducted as part of the screening. Participants who do not need surgery or whose epilepsy cannot be treated surgically will follow up with a primary care physician or neurologist and will not need to return to the National Institutes of Health for this study. - Prior to the surgery, participants will have the following procedures to provide information on the correct surgical approach. - Video electroencephalography monitoring to measure brain activity during normal activities within a 24-hour period. Three to four 15-minute breaks are allowed within this period. - Electrodes placed directly in the brain or on the surface of the brain to measure brain activities and determine the part of the brain that is responsible for the seizures (seizure focus). - Participants will have a surgical procedure at the site of their seizure focus. Brain lesions, abnormal blood vessels, tumors, infections, or other areas of brain abnormality will be either removed or treated in a way that will stop or help prevent the spread of seizures without affecting irreplaceable brain functions, such as the ability to speak, understand, move, feel, or see. - Participants will return for outpatient visits and brain imaging studies 2 months, 1 year, and 2 years after surgery.
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.

Multicenter prospective study comparing the diagnosis value of high-resolution EEG and depth-EEG to localize the epileptogenic zone in drug resistant partial epilepsies.
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 whether Eslicarbazepine acetate (BIA 2-093) is an effective adjunct therapy in the treatment of refractory partial seizures
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.
The primary objective was to evaluate the efficacy of eslicarbazepine acetate (ESL) administered once daily at 1200 mg or 800 mg, compared with placebo as adjunctive therapy in patients with refractory partial epilepsy over a 12-week maintenance period.
