Filter by:To investigate the potential antiepileptic effects of cannabidiol (GWP42003-P) in children and adults with Dravet or Lennox-Gastaut syndromes.
The primary objective of this study was to evaluate the efficacy of GWP42003-P as adjunctive treatment in reducing the number of drop seizures when compared with placebo in participants with Lennox-Gastaut syndrome (LGS).
The sponsor is developing a new paediatric formulation of vigabatrin to better adjust the dose to body weight and to limit waste of unused drug. The currently marketed vigabatrin (Sabril™) form only exists as 500 mg film coated tablets (for adults and children above 6 years) and 500 mg granules for oral solution sachets (for infants and children below 6 years). Sabril™ is not adapted for administration to infants when a fraction of the sachet is needed. Manual splitting of the sachet or lengthy and error-prone dilutions are often required. This study is a descriptive, non-randomized, open label multi-centric acceptability study in infants and children affected with infantile spasms. The primary objective is to describe the adherence to the new formulation. Secondary objectives include: - evaluation of the palatability and user-friendliness of the new treatment, - evaluation of the pharmacokinetic parameters of the new formulation, - PK parameters, - evaluation of the tolerance, - measurement of taurine plasma levels. This study will recruit up to 40 patients with infantile spasms and pharmacoresistant partial epilepsy aged 1 month to 6 years in 23 clinical sites in France.
The investigators will conduct a prospective observational cohort study to investigate factors that influence contraceptive method utilization among women with medical conditions. The investigators will also investigate how women with medical conditions access to contraception and family planning fellowship trained specialist. After the baseline questionnaire, there be a 3 month and 6 month follow up questionnaire to investigate continuation and satisfaction with the contraceptive method. This study is unique because it will allow us to explore doing collaborative family planning research at the multiple UC medical campuses.
Approximately a fourth of children with seizures do not respond adequately to available therapy. Ketogenic therapy has a long history as treatment for intractable epilepsy, but there is no agreement concerning how it works and what is the best way to administer it. This natural history study will collect data pertaining to both questions.
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).
Epilepsy, a condition where individuals are prone to recurrent epileptic seizures, is the most common chronic neurological disorder in children. Epilepsy onset is most common in the first two years of life and is associated with poor prognosis for seizure control and neurodevelopmental outcome. The ketogenic diet (KD) is a medically supervised diet that is high in fat and restricted in carbohydrates and protein. KD therapy has shown to be an effective treatment for seizures in children with epilepsy older than two. Associated benefits include: a reduced requirement for routine and emergency antiepileptic drugs (AED) and fewer seizure related hospital admissions. Although reports suggest that KD therapy improves seizures in younger children there is no high quality trial data that demonstrates effectiveness and safety in this age group. The KD is resource intensive, requiring dietetic and physician time; data is required to justify expansion of services to cater for the apparent need. The investigators therefore propose a prospective multicentre randomised trial to investigate the effectiveness and safety of the KD in children with epilepsy under the age of 2, who have failed to respond to two or more AEDs. Children will be randomly assigned to either receive the KD or further AEDs. The allocated treatment will be started after a 2week baseline period, and it's effectiveness assessed after 8 weeks. Seizure diaries will be used to record seizures and related events, a questionnaire will be used to assess diet tolerance; also growth and blood biochemistry will be monitored. The information obtained from this study is necessary to optimise choices in epilepsy treatment, aiming to improve outcomes and thus determine whether and when the KD should should be used.
The purpose of this study is to evaluate the safety of topiramate monotherapy compared with levetiracetam another standard antiepileptic drug (AED), as monotherapy for new-onset or recent-onset epilepsy (seizure disorder) on pediatric growth and maturation, bone mineralization, and kidney stone formation in children aged 2 to 15 years.
This study aims to determine the safety and effectiveness of oral melatonin as natural inducer of sleep to acquire useful EEGs in South African children following its introduction as the main agent used in the Neurophysiology department at Red Cross Children's Hospital. This is an observational retrospective study.
A prospective exploratory study in patients with drug resistant epilepsy with a target comparison of long term outcome. NeuroScan software modules and a MagLink will be used to acquire EEG in combination with MRI/fMRI data. The MagLink system is used for obtaining integrated EEG and Event Related Potential (ERP) recordings while the subject is inside the MRI machine, without compromising the raw EEG data.
