This research study is being done to see the effectiveness and safety of a new drug called BHV-7000 as a possible treatment for focal seizures for patients who are taking anti-seizure medications (ASMs) and still experience seizures. Participation in this study is expected to last approximately 18 to 20 weeks, or about 4 months.

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.

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
scoring.

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.
