SUDEP typically occurs during sleep, after a nocturnal seizure, and primarily results from a postictal central respiratory dysfunction in patients with generalized convulsive seizure (GCS), suggesting that interaction between respiratory dysfunction and sleep state may play a role in its pathophysiology.\n\nPost-mortem data in SUDEP patients showed alteration of neuronal populations involved in respiratory control in the medulla. Accordingly, pharmacologic strategies aimed at reducing the severity of postictal respiratory dysfunction has appeared as one of the most promising way to prevent SUDEP. However, no encouraging result has hitherto been reported.\n\nInterconnections between the complex network that regulates arousal and sleep and the respiratory network are numerous. They primarily include the relation between chemosensitive regulation and arousal system to ensure asphyxia-induced arousal (i.e. arousal to elevated CO2), especially through serotonin (5HT)-dependent connections in brain stem. The link between alterations of the brainstem networks involved in arousal regulation and respiratory dysfunction has not been characterized in patients with epilepsy yet.\n\nLike 5HT, adenosine is deeply implicated in the regulation of sleep and central respiratory control.\n\nSeizures transiently increase adenosine extracellular levels. Adenosine physiological effects in the brain are mediated through the activation of two types of Adenosine receptors (ARs), A1Rs and A2ARs. Extracellular adenosine promotes sleep via A1R-dependant inhibition of glutamatergic neurons in the basal forebrain, but also via A2AR-dependant activation of neurons in the nucleus accumbens. Respiration is also inhibited by A1R and A2AR. Most importantly, it has been shown that drug-resistant epilepsy is associated with long-term alterations of ARs cortical expression. However, whether or not a similar epilepsy-related plasticity of ARs occurs in the brainstem and may participate to chronic arousal and respiratory dysfunction in epilepsy has never been investigated.\n\nConsidering the tight interplay between central respiratory control, arousal regulation and brainstem adenosine, the main hypothesis of the BRAVE study is that epilepsy might result in alterations of the distribution of A1Rs in the brainstem structures involved in respiratory regulation and\u002For arousal control, especially in the brainstem structures involved in respiratory regulation under hypercapnic condition.\n\nThe study combines clinical respiratory characterization, morphological, functional and metabolic imaging, using the hybrid simultaneous 3T MRI-PET scanner (Siemens Biograph mMR) of the CERMEP. Combining PET with anatomical and functional MR imaging enables non-invasively in vivo mapping of receptor binding and functional neuronal assessment of a physiological task in the entire brain with high spatial resolution.\n\nInvestigators already performed fMRI study of respiratory centers, showing number of functional changes in brainstem regions participating to the central control of respiration, including reduced activation during breath-holding fMRI, in patients with epilepsy. The BRAVE study will use the same respiratory paradigm as the one used in this past study.\n\nPET imaging will be focused on A1R, using \\[18F\\]CPFPX, a selective A1R antagonist.",[57,58,59],"Epilepsy","Drug-resistant Focal Epilepsy","Healthy Controls",[57,61,62,63,64],"adenosine pathway","respiratory reactivity","PET-MRI","[18F]CPFPX","2026-08-07",{"date":67,"type":35},"2026-08-11",{"date":65,"type":20},{"date":70,"type":20},"2028-10-07",{"name":72,"class":42},"Hospices Civils de Lyon",1,{"id":75,"slug":76,"hasResults":11,"nctId":77,"briefTitle":78,"officialTitle":78,"acronym":79,"eligibilityCriteria":80,"healthyVolunteers":11,"sex":16,"minAge":17,"maxAge":81,"enrollmentInfo":82,"targetDuration":4,"studyType":21,"phases":84,"briefSummary":85,"conditions":86,"keywords":87,"overallStatus":31,"whyStopped":4,"lastUpdateSubmitDate":92,"lastUpdatePostDateStruct":93,"startDateStruct":95,"completionDateStruct":97,"leadSponsor":99,"locationsCount":4},"100616110","easee-system-pivotal-study-for-the-united-states-of-america-100616110","NCT07301346","EASEE® System Pivotal Study for the United States of America","EASEE4US","Inclusion Criteria:\n\n* Adult between 18-75 years of age\n* Diagnosis of drug-resistant focal epilepsy\n* At least four (4) observable seizure manifestations per month\n* Stable anti-seizure medication regimen\n\nExclusion Criteria:\n\n* Diagnostic of non-epileptic seizures\n* Active idiopathic generalized epilepsy\n* Recent status epileptics (\\\u003C12 months)\n* Clinically significant or unstable medical condition\n* Active psychosis, major depression, suicidal ideation (\\\u003C6 months)\n* Pregnancy\n* Implanted with brain stimulation device or active Vagus Nerve Stimulation","75 Years",{"count":83,"type":20},200,[23],"The goal of this clinical trial is to demonstrate the safety and effectiveness of focal cortex stimulation with the EASEE(R) System in a large cohort of subjects with medically refractory focal epilepsy.
