Objective
Poor medication adherence remains a concern for individuals managing their epilepsy with antiseizure medicines (ASMs); however, ethical concerns around withholding medication make it impossible to study the causal relationship between missed doses and seizures in patients. Previous preclinical studies from our group suggest that mechanistically distinct ASMs have varying degrees of forgiveness...
Objective
The use of many antiseizure medications (ASMs) is limited due to pharmacoresistance and dose‐limiting side effects, suggesting an unmet need for novel therapeutic approaches. The neuropeptide galanin reduces seizures in several preclinical seizure and epilepsy models, but its clinical utility is limited due to rapid metabolism and poor blood–brain barrier penetration. The lead galanin analog...
The Sixteenth Eilat Conference on New Antiepileptic Drugs and Devices (EILAT XVI) was held in Madrid, Spain on May 22–25, 2022 and was attended by 157 delegates from 26 countries representing basic and clinical science, regulatory agencies, and pharmaceutical industries. One day of the conference was dedicated to sessions presenting and discussing investigational compounds under development for the...
The Eilat Conferences have provided a forum for discussion of novel treatments of epilepsy among basic and clinical scientists, clinicians, and representatives from regulatory agencies as well as from the pharmaceutical industry for 3 decades. Initially with a focus on pharmacological treatments, the Eilat Conferences now also include sessions dedicated to devices for treatment and monitoring. The...
Objective
The formation of 24S‐hydroxycholesterol is a brain‐specific mechanism of cholesterol catabolism catalyzed by cholesterol 24‐hydroxylase (CYP46A1, also known as CH24H). CH24H has been implicated in various biological mechanisms, whereas pharmacological lowering of 24S‐hydroxycholesterol has not been fully studied. Soticlestat is a novel small‐molecule inhibitor of CH24H. Its therapeutic...
Objectives
Benzodiazepines are the standard of care for the management of sustained seizure emergencies, including status epilepticus (SE) and seizure clusters. Seizure clusters are a variably defined seizure emergency wherein a patient has multiple seizures above a baseline rate, with intervening periods of recovery, distinguishing clusters from SE. Although these seizure emergencies are phenotypically...
Objective
The kainic acid (KA)‐induced status epilepticus (SE) model in rats is a well‐defined model of epileptogenesis. This model closely recapitulates many of the clinical and pathological characteristics of human temporal lobe epilepsy (TLE) that arise following SE or another neurological insult. Spontaneous recurrent seizures (SRS) in TLE can present after a latent period following a neurological...
Since 1955, several alkyl‐carbamates have been developed for the treatment of anxiety and epilepsy, including meprobamate, flupirtine, felbamate, retigabine, carisbamate, and cenobamate. They have each enjoyed varying levels of success as antiseizure drugs; however, they have all been plagued by the emergence of serious and sometimes life‐threatening adverse events. In this review, we compare and...
The Fifteenth Eilat Conference on New Antiepileptic Drugs and Devices (EILAT XV) was held as a fully virtual conference from July 27 to July 30, 2020 for the sessions on drugs, and on August 3, 2020 for the sessions on devices. A total of 534 delegates from 63 countries attended lectures and interactive discussions, representing a broad range of disciplines from basic science, clinical research, and...
Approximately one‐third of people living with epilepsy are unable to obtain seizure control with the currently marketed antiseizure medications (ASMs), creating a need for novel therapeutics with new mechanisms of action. Cenobamate (CBM) is a tetrazole alkyl carbamate derivative that received US Food and Drug Administration approval in 2019 for the treatment of adult partial onset (focal) seizures...
Since 1992, the Eilat Conferences have provided a forum for all stakeholders in the epilepsy community to appraise the latest data on new antiepileptic drugs and emergency seizure treatments, including, in recent years, updates on progress with the development of novel monitoring and therapeutic devices. Because of the COVID‐19 pandemic, the Fifteenth Eilat Conference on New Antiepileptic Drugs and...
Objective
Current medicines are ineffective in approximately one‐third of people with epilepsy. Therefore, new antiseizure drugs are urgently needed to address this problem of pharmacoresistance. However, traditional rodent seizure and epilepsy models are poorly suited to high‐throughput compound screening. Furthermore, testing in a single species increases the chance that therapeutic compounds act...
Objective
Initial identification of new investigational drugs for the treatment of epilepsy is commonly conducted in well‐established mouse acute and chronic seizure models: for example, maximal electroshock (MES), 6 Hz, and corneal kindling. Comparison of the median effective dose (ED50) of approved antiseizure drugs (ASDs) vs investigational agents in these models provides evidence of their potential...
Objective
Pharmacokinetics (PK) of antiseizure drugs differ considerably between rats and humans. Rodents require larger and more frequent doses to maintain therapeutic drug levels. This study uses the antiseizure drug (ASD) carbamazepine (CBZ) to validate the application of a previously described automated drug delivery system for delivering chronic oral medication to rats.
Methods
Treatment‐naive,...
Objective
Medication nonadherence directly contributes to poor seizure control. A lack of emphasis on correcting poor adherence and failures in patient adherence can result in unwarranted alterations to a patient's drug regimen. We have modeled nonadherent patients in an animal model of epilepsy to study how alterations to pharmacotherapy, made without consideration of a patient's adherence, result...
Objective
Epilepsy is a progressive neurological disease characterized by recurrent seizures and behavioral comorbidities. We investigated the antiseizure effect of cannabidiol (CBD) in a battery of acute seizure models. Additionally, we defined the disease‐modifying potential of chronic oral administration of CBD on associated comorbidities in the reduced intensity status epilepticus–spontaneous...
Objective
Approximately 30% of patients with epilepsy are refractory to existing antiseizure drugs (ASDs). Given that the properties of the central nervous systems of these patients are likely to be altered due to their epilepsy, tissues from rodents that have undergone epileptogenesis might provide a therapeutically relevant disease substrate for identifying compounds capable of attenuating pharmacoresistant...
The Fourteenth Eilat Conference on New Antiepileptic Drugs and Devices (EILAT XIV) took place in Madrid, Spain, on May 13‐16, 2018 and was attended by 168 delegates from 28 countries.

Objective
Despite numerous treatments for epilepsy, over 30% of patients remain resistant to available antiseizure drugs (ASDs). Thus, there is a strong need for more effective ASDs for these individuals. Early ASD discovery has historically relied on acute in vivo seizure models (maximal electroshock, subcutaneous pentylenetetrazol, 6 Hz), which lack the pathophysiology that defines chronic epilepsy...
