Filter by:This is an open label, randomized, prospective study of the impact on healthcare utilization of a surface Electromyography (sEMG) based seizure monitoring and alerting system for Veterans with seizures with upper extremity motor involvement, that are refractory to three or more antiepileptic drugs.
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.
The study aims at validating the diagnostic performances of the METAglut1, a blood in vitro diagnostic test, for the simple and early diagnosis of the Glut1 deficiency syndrome (Glut1DS, or De Vivo disease). The blood test will be carried out prospectively on patients presenting with a clinical suspicion of Glut1DS, blindly from the reference strategy, which consists in a lumbar puncture for glycorrhachia measurement, completed by a molecular analysis. The study will be conducted in more than 40 centers in France on up to 3,000 patients for 2 years.
A Randomized, Single-Dose, Parallel-Group Study to Evaluate the Pharmacokinetic Profiles of Two Formulations of Pregabalin after Oral Administration in Healthy Volunteers under Fasting Conditions
The purpose of the study is to evaluate the safety and tolerability of intravenous (iv) brivaracetam (BRV) as adjunctive therapy administered as a replacement for oral BRV at doses ranging from BRV 50 mg/day to 200 mg/day in Japanese subjects >=16 years of age with partial seizures with or without secondary generalization and to evaluate the partial seizure frequency after switching from oral administration to iv BRV.
This trial is intended to study the safety and effectiveness of an new anti-epileptic drug (AED) on Primary Generalized Tonic-Clonic (PGTC) Seizures. Eligible Subjects, adults and adolescents, will continue to take their usual AEDs and receive either cenobamate or placebo. Subjects will have a 50% chance or receiving cenobamate or placebo (sugar pill). Subjects will initially receive 12.5 mg of cenobamate or placebo (study drug) and increase the dose every two weeks until they reach a target dose of 200 mg. Subjects will take study drug at approximately the same time in the morning (once a day) with or without food. If tolerability issues arise, dosing can be changed to evening. Also, once a subject reaches 200 mg, the dose can be decreased one time to 150 mg, if necessary. The treatment period is 22 weeks and there is a 3 week follow up period, which includes a one week decrease in study drug to 100 mg prior to stopping. Adolescents will follow the same every two week regimen and receive cenobamate as an oral suspension based on weight. Subjects who complete may be eligible for an extension study and will not have to complete the follow up period. Subjects will track their seizure types and frequency in a diary throughout the study.
Epileptic seizures arise from neuronal defects that often alter the capacity of the brain to process sensory information. During absence seizures, a frequent epileptic syndrome in children, the normal conscious and perceptual processes are temporarily interrupted. This is the result of abnormal synchronized neural activities in the thalamo-cortical loops, leading to bilateral spike-and-wave discharges (SWDs) in the cortical electroencephalograms (EEGs). The brain mechanisms underlying the lack of sensory experience during absence seizures are disputed. Based on preliminary data, the investigators hypothesize that the alternation of 'spike' and 'wave' patterns during seizure could cause a time-to-time inconstancy in cortical responsiveness, preventing conscious perception. Using a real-time closed-loop stimulation system, the investigators will research how the S- and W-patterns specifically alter the sensory-evoked responses in the EEG. During a standard EEG, visual stimulations will be applied between and during absence seizures to test the hypothesis that repeated sensory stimuli, applied with an appropriate timing relative to the seizure-related oscillatory cycle, could negatively interfere with the regenerative network mechanisms involved in the occurrence of SWDs. The completion of this project should permit to unveil a new neuronal mechanism supporting the lack of conscious experience during absences and pave the way for new clinical non-invasive strategies to interrupt ongoing seizure activity.
This is an observational study based on a population-based EHR database.
This international research project looks at the reliability of canine seizure alerting behaviour in epilepsy patients. In the first stage an international database to identify the size and composition of the population of seizure alerting dogs has been created.
Early Check provides voluntary screening of newborns for a selected panel of conditions. The study has three main objectives: 1) develop and implement an approach to identify affected infants, 2) address the impact on infants and families who screen positive, and 3) evaluate the Early Check program. The Early Check screening will lead to earlier identification of newborns with rare health conditions in addition to providing important data on the implementation of this model program. Early diagnosis may result in health and development benefits for the newborns. Infants who have newborn screening in North Carolina will be eligible to participate, equating to over 120,000 eligible infants a year. Over 95% of participants are expected to screen negative. Newborns who screen positive and their parents are invited to additional research activities and services. Parents can enroll eligible newborns on the Early Check electronic Research Portal. Screening tests are conducted on residual blood from existing newborn screening dried blood spots. Confirmatory testing is provided free-of-charge for infants who screen positive, and carrier testing is provided to mothers of infants with fragile X. Affected newborns have a physical and developmental evaluation. Their parents have genetic counseling and are invited to participate in surveys and interviews. Ongoing evaluation of the program includes additional parent interviews.
