NCT03478982
This is a multi-center, double-blind, randomized, parallel group, dose-ranging study to investigate the efficacy and clinical usability of STAP-001 in adult (18 years of age and older) subjects with epilepsy with a predictable seizure pattern. These subjects have an established diagnosis of focal or generalized epilepsy with a documented history of predictable seizure episodes. This is an in-patient study. The subjects will be admitted to a Clinical Research Unit (CRU) or Epilepsy Monitoring Unit (EMU) for study participation. The duration of the stay in the in-patient unit will be 2-8 days. One seizure event per subject will be treated with study medication. The duration and timing of the seizure event and occurrence of subsequent seizures will be assessed by the Staff Caregiver(s)1 through clinical observation and confirmed with video electroencephalogram (EEG).
NCT04737369
Theoretical Framework \& Background Cortical spreading depressions (CSD) and seizures, are crucial in the development of delayed cerebral ischemia and poor functional outcome in patients suffering from acute brain injuries such as subarachnoid hemorrhage. Multimodal neuromonitoring (MMNM) provides the unique possibility in the sedated and mechanically ventilated patients to record these electrophysiological phenomena and relate them to measures of cerebral ischemia and malperfusion. MMNM combines invasive (e.g. electrocorticography, cerebral microdialysis, brain tissue oxygenation) and noninvasive (e.g. neuroimaging, continuous EEG) techniques. Additionally, cerebral microdialysis can measure the unbound extracellular drug concentrations of sedatives, which potentially inhibit CSD and seizures in various degrees, beyond the blood-brain barrier without further interventions. Hypotheses 1. Online multimodal neuromonitoring can accurately detect changes in neuronal metabolic demand and pathological neuronal bioelectrical changes in highly vulnerable brain tissue. 2. Online multimodal neuromonitoring can accurately detect the impact of pathological neuronal bioelectrical changes on metabolic demand in highly vulnerable brain tissue. 3. The occurrence and duration of pathological neuronal bioelectrical changes are dependent on sedatives and antiepileptic drug concentrations 4. The occurrence and duration of pathological neuronal bioelectrical changes have a negative impact on functional and neurological long-term patient outcome. 5. Simultaneous invasive and non-invasive multimodal neuromonitoring can identify a clear relationship of both methods regarding pathological neuronal bioelectrical changes and metabolic brain status. Methods Systematic analysis of MMNM measurements following standardized criteria and correlation of electrophysiological phenomena with cerebral metabolic changes in all included patients. In a second step neuroimaging, cerebral extracellular sedative drug concentrations and neurological functional outcome, will be correlated with both electrophysiologic and metabolic changes. Due to numerous high-resolution parameters, machine learning algorithms will be used to correlate comprehensive data on group and individual levels following a holistic approach. Level of originality Extensive, cutting edge diagnostic methods are used to get a better insight into the pathophysiology of electrophysiological and metabolic changes during the development of secondary brain damage. Due to the immense amount of high-resolution data, a computer-assisted evaluation will be applied to identify relationships in the development of secondary brain injury. For the first time systematic testing of several drug concentrations beyond the blood-brain barrier will be performed. With these combined methods, we will be able to develop new cerebroprotective treatment concepts on an individual basis.

NCT00143130
To evaluate long-term efficacy and safety of pregabalin (150 to 600mg/day) as adjunctive treatment in patients with partial seizures.
NCT04727892
Epilepsy surgery is effective for refractory epilepsy, particularly focal epilepsy, but is still underutilized worldwide. In the United States, the annual percentage of surgical procedures for refractory epilepsy was low (range: 0.35%-0.63%) from 2003 to 2012. Fear associated with the risks of invasive procedures may be the reason for the cautious attitude towards epilepsy surgery. Therefore, the risks of epilepsy surgery in the modern age need to be evaluated thoroughly and precisely to improve epilepsy surgery outcomes. The safety of epilepsy surgery has been confirmed in several studies. Studies on this topic with large sample sizes (\> 500 patients) were either multicenter or covered a long study period. In addition, high-resolution magnetic resonance imaging (MRI) was not used in the early stage in these studies. Differences in medical environment among epilepsy centers and advancements in presurgical evaluations and surgical techniques over time may have caused heterogeneity and biases, thereby limiting the quality of these studies. Over the past two decades, there was no large-scale studies on post-epilepsy surgery complications performed at a single center. Moreover, surgery-related complications are seldom graded according to severity. Especially, the risk factors for these complications remain unclear.
NCT01220180
This study collects post-marketing safety and efficacy surveillance data in real world clinical use of pregabalin for its approved indications in Korea.
NCT00141258
To evaluate the efficacy of pregabalin as adjunctive therapy, using a flexible, optimized dose schedule with dose adjustment based on clinical response and tolerability, compared to placebo in subjects with partial seizures
NCT00288639
The objective of study is to assess the clinical improvement (change in seizure frequency), safety, and tolerability of subjects with partial seizures following adjunctive therapy of pregabalin BID (150 to 600 mg/day titration) in addition to existing standards AEDs.
NCT02072824
This study is designed to evaluate the effectiveness of 2 doses of pregabalin to reduce seizure frequency as an add on therapy in pediatric subjects 1 month to \<4 years of age with refractory partial onset seizures. It is hypothesized that both doses of pregabalin will demonstrate superior efficacy when compared to placebo by reducing the partial onset seizure frequency and that pregabalin will be safe and well tolerated.
NCT00279851

NCT02408523
Evaluating efficacy \& safety of lacosamide versus Placebo in a blinded fashion as add-on Therapy for Primary Generalized Tonic-clonic (PGTC) seizures in subject 4 years of age or greater with idiopathic generalized epilepsy currently taking 1 to 3 antiepileptic drugs. Maximum duration of study drug administration is 28 weeks. Eligible subjects may choose to enter the open-label extension study after completion.
NCT01995825
In this study, brand name lamotrigine (LAMICTAL) and generic lamotrigine will be compared in patients with epilepsy. Both the brand name and generic lamotrigine are approved by the Food and Drug Administration (FDA) and are commonly used to treat epilepsy. Some physicians and patients with epilepsy have believed that brand and generic lamotrigine have had clinically significant differences in efficacy and tolerability. The brand name and generic tablets have been shown to be the same when blood levels were measured in healthy volunteers without epilepsy, but these drugs have not yet been compared in patients with epilepsy. This study will do this comparison, by switching patients between brand and generic in a very structured manner, and seeing if the drugs are the same, primarily in terms of blood levels. Other comparisons will also be made secondarily, looking for any differences in adverse effects and seizure control.
NCT01494584
This is an open-label study to evaluate the pharmacokinetics, safety and tolerability of ezogabine/retigabine in subjects aged 12 years to less than 18 years with uncontrolled partial onset seizures or Lennos-Gastaut syndrome.
NCT02207673
Epilepsy occurs in 0.5-0.7% of the population, of which 25% are children. 30% Of patients with focal epilepsy do not respond well to medication and half of them are eligible for epilepsy surgery. In recent years, the importance of early epilepsy surgery has been stressed, as successful surgery may lead seizure and medication freedom and improved social and cognitive development, especially in children. The current success rate of epilepsy surgery is around 65%; During surgery intracranial electrocorticography (acute ECoG, aECoG) is recorded in some medical centers. The presence of epileptiform brian activity, spikes, identified by clinical neurophysiologists, is used to guide the neurosurgeon in the extent of the brain tissue that needs to be resected. Spikes are considered markers of the presence of epilepsy. High Frequency Oscillations (HFOs, \>80-500Hz) in the ECoG have recently been identified as a new biomarker for epileptogenic tissue. Retrospective research shows that their local presence strongly relates to the seizure onset, and removal of tissue with HFOs could predict a better surgical outcome. The area showing HFOs usually overlaps with, but is smaller than the area with spikes, and HFOs do not tend to propagate to distant sites as spikes do. The identification of HFOs is more objective than of spikes and automatic detection software exists. A pilot study is performed to test the hypothesis : The intra-operative use of HFOs to delineate the epileptogenic cortex does not yield significantly worse outcome in seizure freedom than the current method based on spikes. Study design is a single blinded multi-center randomized controlled trial. In two Dutch centers, the VU medical center ( Amsterdam) and University Medical Center Utrecht. The study population (sample size 78) consists of patients of all ages with refractory epilepsy undergoing epilepsy surgery with aECoG to guide the extent of the resection. Eligible patients are randomised, after informed consent, into group 1 (HFOs) in whom a resection guided by HFOs in the aECoG (new), or into group 2 (spikes) in whom a resection is guided by epileptiform spikes in the aECoG (current standard). Ictiform spike patterns will always be resected. Main study endpoint is outcome after epilepsy surgery after 1 year of follow-up dichotomized in total seizure freedom (Engel Ia\&b) vs. seizure recurrence (Engel Ic-IV).
NCT04573803
The overall aim of the MAST trial is to define best practice in the use of anti-epileptic drugs (AEDs) for patients following a traumatic brain injury (TBI). The trial will consist of two parts. The first part aims to answer whether a shorter or a longer course of AEDs is better to prevent further seizures in patients who have started having seizures following TBI (MAST - duration). The second part aims to answer whether a 7-day course of either Phenytoin or Levetiracetam should be used for patients with a serious TBI to prevent seizures from starting (MAST- prophylaxis).
NCT03464383
As a potential solution to address high rates of depression and anxiety seen in epilepsy patients and poor mental health care access, this randomized trial aims to study treatment for anxiety and depression in epilepsy taking place directly within the epilepsy clinic vs. psychiatry referral (typical care). Patients that meet eligibility criteria, including significant symptoms of depression and/or anxiety, will be randomized to the either the intervention group or the control group. Patients that do not meet eligibility requirement or decline the study intervention will have the option of participating in the survey arm of the study. The intervention will consist of an initial prescription for an FDA-approved medication to treat depression/anxiety and telephone-based chronic care management plan for repeated symptom measurement and side effect surveillance. The control group will receive usual care, which is a referral order to psychiatry placed by their treating neurologist. Participants in the survey arm of the study will complete a one time survey.
