Study is the first study after commercialization of brivaracetam. It is designed to collect real world information on the effectiveness of brivaracetam in patients with Partial Onset Seizure epislepsy who are treated in standard clinical practice.
Study 1 and Study 3 are the prospective, merged analyses of 2 identical double-blind, placebo-controlled studies, ZX008-1501 and ZX008-1502, to assess the efficacy, safety, and pharmacokinetics of ZX008 when used as adjunctive therapy in pediatric and young adult subjects with Dravet syndrome. Study 1501 and Study 1502 were conducted in parallel; Study 1501 was conducted at approximately 30 study sites in North America; Study 1502 was conducted at approximately 30 study sites in Europe, Asia and Australia. Upon completion of the Baseline Period after initial Screening and Baseline charting of seizure frequency, subjects who qualified for the studies were randomized (1:1:1) in a double-blind manner to receive either 1 of 2 doses of ZX008 (0.2 mg/kg/day or 0.8 mg/kg/day; maximum dose: 30 mg/day) or placebo. Randomization was stratified by age group (< 6 years, ≥6 to 18 years) to achieve balance across treatment arms, with the target of 25% of subjects in each age group. All subjects were titrated to their randomized dose over a 14-day Titration Period. Following titration, subjects continued treatment at their randomly assigned dose over a 12-week Maintenance Period. Subjects exiting the study underwent a 2-week taper, unless they enrolled in a follow-on study. Subjects were followed for post-study safety monitoring.
SAVE is a stratified cluster-randomised controlled, parallel group, open-label trial, with Epileptic Monitoring Unit (EMU) as the units of randomisation and patients as the unit of analysis. The focus of research is the management of AntiEpileptic Drugs (AEDs) withdrawal during long term Video EEG (VEEG) monitoring in patients with drug resistant seizures. This non-standardised medical practice, which aims at promoting the occurrence of seizures during the time limit of the monitoring period, exposes patients to significant risks which should be minimised by harmonisation of practice and a standardised protocol of AEDs withdrawal. SAVE will assess the impact of a standardised protocol of AEDs withdrawal during long-term VEEG monitoring on the frequency of seizure-related serious adverse events occurring during these monitorings and on the ability to obtain VEEG recording of seizures within appropriate time limits. 10 of the 22 EMUs will be randomised to the group where the standardised protocol of AEDs withdrawal will be used systematically, while the other ten EMUs will continue their current non-standardised practice of AEDs withdrawal, and will serve as a control group. The setting of the study will include a 6 months evaluation phase, prior to randomisation, during which the organisational characteristics, baseline EMUs' activity, current management of AEDs withdrawal, and rate of Serious Adverse Events (SAEs) of each participating center will be evaluated. The standardised study protocol of AEDs withdrawal has been defined on the basis of a systematic review of all relevant publications in the field.
The aim of this study is to compare quality of care and patient experiences in two outpatients follow-up activities: 1) Standard telePRO (fixed interval telePRO follow-up) and 2) Open Access telePRO (patient-initiated telePRO follow-up)
This project intends to investigate children with idiopathic and cryptogenic localization related epilepsies, using a longitudinal assessment of structural and functional MRI data, in relation to neuropsychological evaluation. The rationale is primarily based on: 1) the frequent observation of selective cognitive dysfunctions in such children, the pathophysiology of which remains largely uncertain; 2) the recent major advances in the MRI investigation of brain maturation showing striking age and region dependant patterns. The primary hypothesis is that some children with localization related epilepsies suffer from altered maturation in the epileptic brain regions, and that this abnormal maturation affects their cognitive abilities. 100 children with localization related epilepsies and 100 matched controls will be prospectively enrolled during the first two years of the disease (for patients) and benefit from a comprehensive phenotypic and neuropsychological evaluation once a year for 5 years. The brain maturation of these children will be longitudinally assessed using structural and functional MRI, and correlated with neuropsychological data. Investigators hope to demonstrate that children with localization related epilepsies and cognitive dysfunctions suffer from an abnormal brain maturation in regions underlying the epileptic activity and the altered cognitive processes. The finding could partly bridge the gap between these two abnormalities and help better understand their interaction and respective dynamic. Once validated, the study of regional brain maturation in children with epilepsy might be further used as a reliable surrogate marker or predictor of associated cognitive dysfunction.
The long-term goal of this research is to improve seizure control among patients with epilepsy, which has the potential to improve quality of life for thousands of people living with epilepsy and reduce health care utilization, social and economic costs, and epilepsy-related mortalities. Participants who are suffering from epilepsy will be randomized to receive usual care (UC), a smartphone-based self-management intervention called Management of Risks in Epilepsy (MORE), or MORE + telephone-based motivational interviewing (MI). Participants will be followed for 3 months.
This is a pilot study to determine if a standard bolus dose and infusion of dexmedetomidine can significantly decrease the dose of propofol (infusion) required for accomplishing an MRI. The investigators studied three arms to examine the effectiveness of dexmedetomidine. Arm 1 was a single bolus of 1.0 mcg/kg with 1.0 mcg/kg/hr infusion followed by propofol infusion. Arm 2 was a bolus of 1.0 mcg/kg with 0.5 mcg/kg/hr infusion followed by propofol infusion. Arm 3 was only a single bolus of 1.0 mcg/kg with no infusion followed by propofol infusion.
Haemorrhagic strokes represent about 10-15 % of all strokes and 30,000 cases per year in France. The 30-day death rate ranges from 30 to 55% (50% of deaths occurring within 48 hours). Currently, no urgent medical or surgical treatment has been shown to improve functional or vital prognosis. Clinical epileptic seizures frequency in acute intracerebral haemorrhage has been estimated between 4% and 16% but the occurrence of subclinical epileptic seizures (detected on the electroencephalogram (EEG) only) could be much more frequent (28 % to 40 %). Some studies have suggested that early repeated epileptic seizures may be associated with a worse neurological prognosis. Repeated epileptic seizures occurring in the acute phase may increase brain oedema, worsen, hypoxia and may lead to cellular death in the injured brain tissue. Thus, prevention of early epileptic seizures may improve neurological outcome. However, the efficacy of a systematic prophylactic antiepileptic treatment on clinical and subclinical epileptic seizures has not been evaluated in the setting of intracerebral haemorrhage. The current European guidelines recommend the use of antiepileptic drugs only when epileptic seizures occur. Primary objective: PEACH is a randomized controlled trial aiming at evaluating the impact of systematic prophylactic antiepileptic treatment with levetiracetam versus placebo in acute supratentorial spontaneous intracerebral haemorrhage. The primary endpoint is the occurrence of at least one clinical or electrical epileptic seizure recorded on continuous 48h holter EEG. Secondary Objectives:This study also aims to assess: Ä The efficacy of prophylactic treatment with levetiracetam on the number of EEG seizures, on the total duration of epileptic seizures continuously recorded on EEG, on the occurrence of some paroxysmal EEG patterns, on the number of clinical seizures occurred during 72 hours of diagnosis, on the occurrence of early (day-0 to day-30 ) and late (from day-30 to 12 months) clinical seizures, on the functional prognosis at 3 , 6 and 12 months evaluated by the modified Rankin scale , on the cerebral oedema and mass effect evaluated by comparing the admission brain CT scan with the control CT scan performed at 72 hours, on the neurological status as assessed by the National Institute of Health Stroke Scale at 72 hours , 1 month and 3 months and on the quality of life measured by the Stroke impact Scale at 3, 6 and 12 months. Ä The frequency of side effects related to treatment with levetiracetam (anxiety and depression assessed by the Hospital Anxiety and Depression Scale at 1 and 3 months) Sample Size: 104 patients will be recruited over 2 years.
The prevalence of epilepsy is about 0.5% to 1% worldwide, with high disability and mortality rate. The 128-channel electroencephalograph (EEG), combined with BESA dipole localization method, is able to provide more specific information about the brain activity and find out the epileptogenic focus. Based on this novel EEG recording method, cathode transcranial direct current stimulation (tDCS) targeting the epileptogenic focus can be used to decrease the excitability of the cortex, thus reducing the frequency of seizures. A single-center double-blinded randomized controlled and open-label extension trial will be carried out to study the efficacy of 128-channel electroencephalograph combined with BESA dipole localization method and Intervention on brain waves for epilepsy.
