The main purpose of this study is to determine if XEN1101 can reduce the seizure frequency and if it is safe to use. Subjects who successfully completed and did not terminate early from one of the antecedent studies (X-TOLE2, X-TOLE3, or X-ACKT) are eligible to participate in X-TOLE4. Following enrollment into X-TOLE4, subjects will undergo a treatment period of up to 3 years, during which there will be a visit at 2-, 4-, and 13-weeks post-entry, with subsequent visits occurring at 13-week intervals during the first year, and then at 26-week intervals (with a telephone call in between) until dosing is completed. All subjects will be initially assigned to receive 25 mg QD of XEN1101. Study drug is to be taken with the evening meal. Subjects will be expected to keep a daily seizure eDiary with a minimum of 80% compliance for the duration of the extension study (reporting on ≥80% of days between visits).
Upon completion of dosing at the end of the treatment period, there will be an 8-week follow-up period.
In this research study a study drug named XEN1101 is being tested for the treatment of seizures. The main purpose of this study is to determine if XEN1101 can reduce the number of seizures and if it is safe to use. XEN1101 has been tested in other studies in epilepsy patients and it was considered to be well-tolerated. It had side effects that are similar to other anti-seizure medications commonly used to help patients with epilepsy.
This study is being done to understand whether a different type of electroencephalography (EEG) monitoring that permits longer monitoring is able to capture more seizures than regular EEG monitoring, and whether this new type of monitoring will improve clinical care. This type of EEG monitoring (REMI) is currently cleared by the United States Government Food and Drug Administration (or FDA) for use in hospitals but not yet cleared to be used at home.
Eligible subjects who have EEG monitoring scheduled with either a 3-day EEG monitoring performed at home or with a 3-day EEG monitoring schedule at the Medical University of South Carolina (MUSC). Subjects are in the study for approximately 4 weeks and will need to come to the study center for one or two visits. They will be asked to wear 4 of Epitel's REMI Sensors on their head, in addition to the regular EEG electrodes, for two 2-week REMI EEG monitoring periods. A 2nd visit (clinic visit) at MUSC may be needed if the recording is at MUSC, in order to start the second REMI EEG monitoring session.
At the end of the study, three independent epileptologists will review the REMI EEG recordings and compile a report of any findings. They will then provide this report to the subject's neurologist who will assess the value of the additional EEG information, and save the report within the MUSC medical record.
Several studies and scientific literature have demonstrated a link between this specific musical work and seizures. Specifically, Mozart's Sonata for Piano in D major has been previously shown to reduce seizure frequency in patients with epilepsy. Our aim is to better ascertain the electrical and clinical response in the setting of a controlled environment, with the ability to monitor brain function during exposure to this classical work or white noise.
The purpose of this study is to understand whether there may be certain characteristics or patterns that might predict seizure events in patients undergoing EEG monitoring and at home. Researchers will also be assessing the comfort and usability of a new device called NextSense EEG earbud device at the same time as routine inpatient epilepsy monitoring unit (EMU) admissions, as well as device use in the home environment. In order to enroll in the at-home extension, the participant must be enrolled in the inpatient EMU admission portion of the study. Participants will be asked to assess their mood, sleep quality, and the comfort and usability of the device during their inpatient admission at regular intervals. If participating in the at-home extension, these same assessment questionnaires, in addition to a seizure diary, will be completed by participants at regular intervals.
This is a study designed to assess whether there will be injury to the liver in participants who are already being treated Epidiolex or who are about to begin treatment with Epidiolex
Participants ages 4 and above on existing Epidiolex treatment for FDA-approved indications and participants with no previous experience of Epidiolex and who are about to be prescribed Epidiolex for an FDA-approved indication will be recruited from multiple sites in the US.
This study will include a screening period of up to 21 (± 7) days to assess participant eligibility. A physical exam, blood/serum laboratory tests and laboratory
This study aims to improve access of Veterans with epilepsy living in rural areas to the most important diagnostic procedure for the care of patients with epilepsy: the routine electroencephalogram (EEG). We will test a new method for recording EEG which uses a novel dry electrode system headset that does not require an EEG technologist to operate. The headset integrates the EEG electrodes and amplifier into a compact system which is easily placed on the head. This approach could make it possible for a nurse or nurse assistant with minimal training to record an EEG in a rural community based outpatient clinic (CBOC) as part of an epilepsy telemedicine outreach program along with clinical interviews. We will compare performance of this dry electrode system to standard EEG when it is used by EEG technologists in three VA medical centers. This project has the potential to improve access of Veterans to the EEG procedure and decrease cost to the Veterans Health Care System.
This 57-week, active-treatment, open-label (all participants will receive study drug throughout the study) extension trial ( enrolls participants of a previous clinical trial into another study) in which all participants gets the study drug is designed to assess the safety and tolerability of CVL-865 as adjunctive treatment (another treatment used together with the primary treatment) in subjects with drug-resistant focal onset seizures. This trial is open to subjects who completed treatment with the investigational medicinal product (IMP) in the double-blind (neither the participant or researchers know what study drug they are receiving) Phase 2 Trial CVL-865-SZ-001 and who, in the opinion of the investigator, could potentially benefit from treatment with CVL-865. There are 17 visits for a duration of 57 active-treatment weeks. The visits are approximately one month apart.
The purpose of this research study is to study the capabilities of new methods for studying the brain using Magnetic Resonance Imaging (MRI). MRI already provides detailed images of brain anatomy, but newer methods including new MRI techniques and magnetic resonance spectroscopy expand this capability. These new MRI methods will not require any invasive procedures. If successful, these new methods will expand the information, which can be obtained from MRI studies of the brain in patients with epilepsy.
Neurological diseases are the leading cause of disability worldwide and a major contributor to health problems in children and adults. As the majority of these conditions result in lifelong disabilities, the implications for the family and for society is significant.
A significant number of adult and childhood neurological diseases have a genetic component and are caused by changes in our DNA and/or RNA leading to functional changes in the central nervous system. However, for many patients afflicted with these disorders, traditional genetic testing does not identify a clear genetic cause. The goal of this study will be to use newer genetic techniques to evaluate patients and families with neurological disorders to better understand the genetic basis of the disease.
