28 Clinical Trials for Various Conditions
This will be a prospective, open-label, single-arm, multi-center, pilot study to evaluate the safety, tolerability, and preliminary efficacy of low-intensity focused ultrasound (LIFU) neuromodulation using NaviFUS System in patients with drug-resistant unilateral or bilateral temporal lobe epilepsy (DR-TLE).
Ketamine is a medication that came into clinical practice in the 1960's. Ketamine is used as an anesthetic and to provide pain relief. Recently, Ketamine was approved to treat drug resistant depression using subanesthetic doses. In the hospital setting, intravenous anesthetic dosages are used to treat unrelenting seizures known as status epilepticus in comatose patients. Ketamine in subanesthetic doses has not been tried as a treatment for medication resistant seizures in the outpatient setting. This study would like to examine the effectiveness of subanesthetic ketamine in outpatients who suffer from drug resistant epilepsy.
The purpose of the study is to evaluate the efficacy, safety and tolerability of the 3 selected dose regimens of padsevonil (PSL) administered concomitantly with up to 3 anti-epileptic drugs (AEDs) compared with placebo for treatment of observable focal-onset seizures in subjects with drug-resistant epilepsy.
This study will investigate whether a Vagal Nerve Stimulator (VNS) causes measurable desynchronization and reduces epileptiform activity, such as spikes and seizures, in electrocorticograms (ECOGs) recorded by a Responsive Neurostimulator (RNS) in patients who have both devices implanted. Specific aims of the study: 1. Evaluate the change in frequency of epileptiform discharges during active VNS stimulation compared to interstimulation baseline periods 2. Evaluate the change in frequency of seizures during active VNS stimulation compared to interstimulation baseline periods 3. Evaluate the change in the number of RNS activations during active VNS stimulation compared to interstimulation baseline periods 4. Evaluate the change in synchronization of background ECoG (electrocorticogram) during VNS stimulation compared to interstimulation baseline periods.

Background: - The blood-brain barrier separates the brain from the rest of the body. Epilepsy is a neurological disease that causes seizures. It can affect this barrier. Researchers think a contrast agent called mangafodipir might be better able to show areas of the brain that epilepsy affects. Objective: - To see if mangafodipir is well tolerated and safe. To see if it can show, on an MRI, areas of the brain that epilepsy affects. Eligibility: * People ages 18-60 who: * Have epilepsy not controlled by drugs * Prior or concurrent enrollment in 18-N-0066 is required Design: * Participants will be screened with: * Medical history * Physical exam * Blood and urine tests * Participants will have up to 6 visits in 1-3 months. Those with epilepsy will have an inpatient stay lasting 2-10 days. Visits may include: * Video-EEG monitoring for participants with epilepsy * An IV catheter put in place: a needle guides a thin plastic tube into an arm vein. * Getting mangafodipir through the IV. * 5 MRI scans over a 10-day period: a magnetic field and radio waves take pictures of the brain. Participants lie on a table that slides into a metal cylinder. They are in the cylinder for 45-90 minutes, lying still for up to 10 minutes at a time. The scanner makes loud knocking sounds. Participants will get earplugs. * A final MRI at least 2 weeks after receiving mangafodipir. Gadolinium is given through an IV catheter.
The main goal of this study is to provide treatment with cannabidiol (CBD) to children with drug resistant epilepsy through a Physician Expanded Access Investigation New Drug protocol. As the controlled therapeutic use of CBD in children is novel, the primary objective of this study is to evaluate the safety and efficacy of CBD when administered as adjunctive therapy in children that have exhausted the majority of FDA approved antiepileptic drug treatment options.
This open-label, multi-center study is open to patients 1 to 18 years of age at time of enrollment with medication resistant epilepsy.
Part A: To evaluate the safety and tolerability of multiple ascending doses of GWP42003-P compared with placebo with respect to: * Incidence, type and severity of adverse events (AEs) * Effect on vital signs, including weight * Effect on 12-lead electrocardiogram (ECG) findings * Effect on laboratory parameters Part B: To make an assessment of the anti-epileptic efficacy of GWP42003-P compared with placebo with respect to the incidence in convulsive seizures * To determine the plasma concentration time curves for GWP42003-P and its major human metabolite, following escalating multiple doses of GWP42003-P. * To investigate the effect of GWP42003-P on the pharmacokinetics of concomitant anti-epileptic drugs (AEDs). * To evaluate cognitive function, sleep quality and daytime sleepiness, in patients taking GWP42003-P in combination with AEDs.
The purpose of this project is to conduct a trial to assess whether patients that receive a tablet-based waiting room priority communication tool (the "Epilepsy Visit Planner") have improved outcomes compared to patients that do not receive the tool. The project's hypotheses are: * Patients that receive the Epilepsy Visit Planner will have improved patient-provider communication compared to the non-planner group. * Patients that receive the Epilepsy Visit Planner will have improved quality of life scores. * The Epilepsy Visit Planner will score highly on process measures of feasibility and acceptability, demonstrating suitability for future larger scale study. Additionally, there is a related survey project that is not part of the clinical trial and will not be included in this registration information.
Interoception, or sensation from inside the body, is involved in a variety of clinical symptoms, such as tics, compulsions and negative mood. This study uses invasive recordings of brain activity and brain stimulation to better understand basic neural mechanisms of interoception and related behaviors. Outcomes of this study provide critical tools for future investigation into clinical symptoms that emerge from abnormal interoception.
The aim of the proposed pilot study is to investigate patient tolerability and efficacy of moderate term, repeated exposure of Pulsed Low-Intensity Focused Ultrasound (PLIFUS) in patients with drug-resistant temporal lobe epilepsy.
This is a treatment study under an approved Expanded Use IND protocol for using Cannabidiol (CBD) Extract. CBD will be used for the treatment of 5-10 children with drug resistant epilepsy. The CBD used in this study is prepared at the University of Mississippi under approval of the National Institute on Drug Abuse (NIDA) for its preparation and FDA approval under an expanded access mechanism on a compassionate use basis. The target patient population is who would otherwise have no appropriate remaining treatment modality left. These are patients for whom the risks of a relatively untested product are outweighed by the potential benefit. Using seizure-diaries to register seizure frequency, drug log and questionnaire to measure parent/patient quality of life and side effects will be assessed in each visit. Visits are: baseline, 4, 8, and 12 weeks visit. A 24 weeks visit (6 months) will be performed if the patient is stable on therapy during the 3 initial months and want to continue on the study for 3 more months. CBD will be administered as an adjunct to all current anti-epileptic therapies.

This is a parallel-arm, double-blind, placebo-controlled study with a screening phase that includes a 28-day run-in phase to establish baseline seizure frequency, followed by a 24-week, randomized, placebo-controlled phase. After completion of the randomized, placebo-controlled phase, participants may enter a 48-week, long-term, extension phase during which they will receive open-label treatment with vatiquinone.
The main reason for this research study is to gain information about how the brain makes seizures by causing seizures using very small amounts of current, or electrical stimulation. Using small amounts of current to cause seizures (or stimulate) is not new at CCHMC - it is part of routine clinical practice for some patients at some electrodes. This study differs from routine clinical care in that all study patients will undergo electrical stimulation in all or nearly all electrode contacts. The study team is doing this because there is promising data in adult patients that stimulating comprehensively (targeting all or nearly all of the electrode contacts) helps define the seizure network. Defining the seizure network in turn helps the medical team plan surgery. So far, there is not as much published data on seizure stimulation for pediatric patients. This research study thus has the potential both to help individual patients (by providing specific information about your seizure networks) and to help pediatric patients with epilepsy in general (by increasing our understanding of stimulated seizures in children, teenagers and young adults).
The purpose of this study is to determine the tolerability and optimal dose of cannabidiol (CBD) as an simultaneous treatment in children and young adults with Sturge-Weber syndrome (SWS) and drug resistant epilepsy.
The primary efficacy objective of the study is to determine if adjunctive therapy of natalizumab 300 mg intravenous (IV) every 4 weeks reduces the frequency of seizures in adult participants with drug-resistant focal epilepsy. The secondary efficacy objective is to assess the effects of natalizumab versus placebo in drug-resistant focal epilepsy on additional measures of seizure frequency.
This is a multicenter, single arm, open label clinical trial that is designed to test the safety and preliminary efficacy of single administration inhibitory nerve cells called interneurons (NRTX-1001), into both temporal lobes of subjects with drug-resistant bilateral mesial temporal lobe epilepsy.
This clinical trial is designed to test whether a single image-guided intracerebral administration of inhibitory nerve cells, called interneurons (NRTX-1001), into subjects with drug-resistant unilateral mesial temporal lobe epilepsy (MTLE), with or without mesial temporal sclerosis (MTS), is safe (frequency of adverse events) and effective (seizure frequency). NRTX-1001 comprises human interneurons that secrete a neurotransmitter, gamma-aminobutyric acid (GABA).
