Active clinical trials for "Epilepsy"

This is a non-randomized open-label extension study for subjects having completed protocol DA071976 or CLN100P.01.

This study is to evaluate the use of glycerol phenylbutyrate for monogenetic developmental epileptic encephalopathies (DEEs). DEEs are characterized by epilepsy and developmental delay in early life. Two examples of DEEs are STXBP1 and SLC6A1, though there are dozens of others. STXBP1 Encephalopathy is a severe disease that can cause seizures and developmental delays in infants and children. SLC6A1 neurodevelopmental disorder is characterized by developmental delay and often epilepsy. Both STXBP1 encephalopathy and SLC6A1 neurodevelopmental disorder cause symptoms because there are not enough working proteins made by these genes. It is possible that a medication called phenylbutyrate may help the the remaining proteins work better for STXBP1, SLC6A1, and/or other similar DEEs caused by single genes (i.e. "monogenetic"). This study is to test if glycerol phenylbutyrate is safe and well tolerated in children with monogenetic DEE.

This is a placebo-controlled study of the effectiveness of transcranial direct current stimulation (tDCS) at home to reduce seizures and EEG spikes.

52 Week Open-Label Safety Study of Cenobamate for Subjects who Complete YKP3089C025 (core study)

Epilepsy affects between 0.5 and 0.7% of the European population. Despite the availability of numerous drug treatments, one third of patients still have seizures, which are associated with significant cognitive and social complications and excess mortality. In these patients, surgical treatment to remove the epileptogenic zone (EZ), the region of the brain responsible for seizures, is the only approach that can allow control of the disease. However, before investigating this surgery, investigations have to answer two questions: (i) what is the location and extension of the EZ and (ii) what functional risks, both motor and cognitive, would represent the resection of this Cortical region? As it is a functional surgery, it is in fact inconceivable that the surgery will result in an over-handicap. For these reasons, all candidates for surgery benefit from a complete assessment including imaging examinations, a neuropsychological assessment and a long-term video-EEG recording to record seizures. Nevertheless, in some patients, this assessment does not give us a formal answer. In these subjects, it is then necessary to carry out a second step, consisting of an invasive exploration by implantation of intracerebral electrodes during a stereoencephalography (SEEG). Due to its temporal and spatial resolution, the SEEG allows, besides the precise determination of the EZ, to carry out a functional mapping of the cortical regions likely to be included in cortectomy. Conventionally, this mapping is carried out on the basis of the cortical electrical stimulations applied to the implanted electrodes. If this approach is very robust for exploring primary functions such as motor skills or language, it cannot be used to evaluate more complex cognitive tasks such as face recognition or attention Effective cognitive treatment on a daily basis. This has led to the development in recent years, in Lyon and Grenoble, of a complementary approach to cerebral stimulation: dynamic spectral imaging (ISD). Numerous experimental paradigms have demonstrated that the realization of a cognitive task associates with the generation within the cortical regions involved in its treatment of a particular cortical activity. This activity is characterized by oscillations of the cortical rhythm in high frequencies (> 30 Hz), called gamma activities. The ISD thus consists in mapping this gamma activity during various cognitive tasks, thus making it possible to study more widely the complexity of the cognitive functions. Correlations between gamma activity and cognitive tasks have so far been exclusively performed in the non-epileptic cortex explored at the periphery of the EA during SEEG. Nevertheless, the cortical oscillatory pattern study associated with a specific cognitive task within the EZ could better anticipate complex cognitive deficits that could be generated by the resection of a cortical region. The main objective of this project is to establish the predictive character of the gamma cortical oscillatory pattern associated with a specific cognitive task on the risk of occurrence of a cognitive disorder after surgery of epilepsy.

The primary objective for this study is to evaluate the long-term safety and tolerability of NBI-827104 in pediatric participants with epileptic encephalopathy with continuous spike-and-wave during sleep (EECSWS).

This trial is a Phase II randomized, double-blind, placebo controlled multi-site study to evaluate the safety and efficacy of early sirolimus to prevent or delay seizure onset in TSC infants. This study is supported by research funding from the Office of Orphan Products Division (OOPD) of the US Food and Drug Administration (FDA).

This is a Phase 3, global, open-label extension (OLE) study of adjunctive GNX treatment in children and adults with TSC who previously participated in either Study 1042-TSC-3001 or Study 1042-TSC-2001

The purpose of this study is to determine whether diazepam reduces the frequency of seizures in GAD65 antibody associated epilepsy.

Therapeutic thermocoagulation will be carried out in patients with drug-resistant focal epilepsy in cases where an epileptogenic zone is found and proven according to stereo-electroencephalography (SEEG) data.
