Active clinical trials for "Epilepsies, Partial"

The purpose of this pilot study is to describe the relationship of regional cerebral oximetry and cytoximetry, measured using near-infrared spectroscopy, with seizure activity in the periictal period in children with epilepsy.

Epilepsy is a disabling neurological disease that affects tens of millions of people worldwide. Despite therapeutic advances, about a third of these patients suffer from treatment-resistant forms of epilepsy and still experience regular seizures.All seizures can last and lead to status epilepticus, which is a major neurological emergency. Epilepsy can also be accompanied with cognitive or psychiatric comorbidities. Reliable seizures count is an essential indicator for estimating the care quality and for optimizing treatment. Several studies have highlighted the difficulty for patients to keep a reliable seizure diary due for example to memory loss or perception alterations during crisis. Whatever the reasons, it has been observed that at least 50% of seizures are on average missed by patients. Seizure detection has been widely developed in recent decades and are generally based on physiological signs monitoring associated with biomarkers search and coupled with detection algorithms. Multimodal approaches, i.e. combining several sensors at the same time, are considered the most promising. Mobile or wearable non invasive devices, allowing an objective seizures documentation in daily life activities, appear to be of major interest for patients and care givers, in detecting and anticipating seizures occurence. This single-arm exploratory, multicenter study aims at assessing whether the use of such a non-invasive, wearable device can be useful in a real life setting in detecting seizures occurence through multimodal analysis of various parameters (heart rate, respiratory and accelerometry).

The goal of the present study is to evaluate ("screen") a large number (12) of different dual therapies of perampanel + another AED ("PMP+") for a large, 75-100% seizure frequency reduction. The design of the study will differ from usual AED studies. The study will be (i) open label, with (ii) a small n per group, n=6, with (iii) outcome measures a 'blockbuster effect': (a) ≥75 seizure frequency reduction; and (b) seizure freedom.

The purpose of study EP0073 is to assess the long-term safety, tolerability, and efficacy during 5 years of treatment with the drug UCB0942 in patients with highly drug-resistant focal epilepsy. Also, the effects of UCB0942 on the patient's quality of life will be explored.

To compare outcomes over 12 months of treatment with antiepileptic drugs (AEDs) alone or vagus nerve stimulation (VNS) therapy plus AEDs in patients who have partial seizures refractory to at least two, but not more than five, AEDs.

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

To prospectively demonstrate the superior anxiolytic effect of high dose pregabalin (PGB) therapy (450 mg/day) compared to low dose PGB therapy (150 mg/day) in subjects with medically refractory partial epilepsy not fully controlled despite treatment with 1-2 concomitant antiepileptic drugs (AEDs).

This is a post-market medical device study. This study will compare best medical practice with or without adjunctive VNS Therapy in patients who are 16 years and older with pharmacoresistant partial epilepsy.

This study is intended to investigate the safety and efficacy of a novel formulation of oxcarbazepine that is released more slowly than the current formulation. The study medication will be used as a treatment against partial epilepsy.

This project is a multicenter prospective study. By retrieving outpatient medical records and collecting clinical data of epilepsy patients, the efficacy and safety of single-drug perampanel in patients with focal epilepsy were analyzed.
