Drug-Resistant Refractory Epilepsy: Understanding

Drug-Resistant Refractory Epilepsy: Overview

Drug-resistant epilepsy (DRE), also referred to as refractory epilepsy, represents a significant clinical challenge and is defined by the persistence of seizures despite adequate trials of at least two appropriately chosen antiepileptic drugs (AEDs) at therapeutic doses. The International League Against Epilepsy (ILAE) estimates that approximately 30% of individuals with epilepsy experience DRE, which leads to considerable morbidity, including a markedly reduced quality of life due to frequent and uncontrolled seizures. Patients with DRE are at heightened risk for cognitive impairments, physical injuries, and a tragic phenomenon known as sudden unexpected death in epilepsy (SUDEP). Diagnosing DRE requires a comprehensive evaluation, including prolonged electroencephalography (EEG) monitoring to accurately classify seizure types and assess the effectiveness of treatments.

The pathophysiology of drug-resistant refractory epilepsy (DRE) is multifaceted and involves a combination of factors that contribute to the failure of antiseizure medications (ASMs) in effectively controlling seizures. One key mechanism is neuroinflammation, where the activation of glial cells, including microglia and astrocytes, leads to the release of pro-inflammatory cytokines. These cytokines exacerbate neuronal excitability, disrupt synaptic function, and promote the formation of abnormal neural circuits, which contribute to the persistence of seizures. Genetic and epigenetic factors also play a critical role in the development of DRE. Mutations in genes involved in the regulation of ion channels, such as those encoding sodium or potassium channels, can lead to altered neuronal firing patterns, resulting in increased hyperexcitability. Additionally, disruptions in neurotransmitter systems, particularly the balance between excitatory glutamate and inhibitory gamma-aminobutyric acid (GABA), further fuel this imbalance, making seizures harder to control. Structural brain abnormalities, such as focal cortical dysplasia or hippocampal sclerosis, create networks of hyperexcitable neurons that are resistant to conventional pharmacological treatments.

The diagnosis of drug-resistant refractory epilepsy (DRE) requires a comprehensive and systematic approach to confirm the condition and identify potential underlying causes. The process begins with a detailed medical history and neurological examination, which helps assess the types of seizures, their frequency, and the impact on the patient’s quality of life. The electroencephalogram (EEG) is a crucial diagnostic tool, providing a record of the brain’s electrical activity and helping to characterize seizure patterns. When seizures remain uncontrolled despite trials of at least two appropriately chosen antiepileptic drugs (AEDs), further diagnostic imaging, such as magnetic resonance imaging (MRI) or computed tomography (CT) scans, is often used to identify structural abnormalities, lesions, or other brain conditions that might contribute to the epilepsy. In addition, advanced techniques like video-EEG monitoring, which combines continuous EEG recording with video surveillance, can offer valuable insights into seizure semiology and help distinguish between epileptic and non-epileptic events, ensuring a more accurate diagnosis.

The treatment and management of drug-resistant refractory epilepsy (DRE) require a multifaceted and individualized approach, particularly when conventional medications fail to adequately control seizures. One option for patients with focal epilepsy is resective surgery, where the goal is to remove the brain region responsible for initiating seizures. This approach has been associated with a high success rate, with many patients experiencing significant reductions in seizure frequency or even achieving seizure freedom. In cases where surgery is not viable, neuromodulation therapies such as vagus nerve stimulation (VNS), responsive neurostimulation (RNS), and deep brain stimulation (DBS) can be used, delivering electrical stimulation to specific brain areas to reduce seizure frequency and severity. Another option is dietary interventions, like the ketogenic diet, which alters metabolic pathways to reduce seizures, particularly in pediatric populations.

Drug-Resistant Refractory Epilepsy Emerging Drugs

NRTX-1001: Neurona Therapeutics

Neurona’s lead product candidate, NRTX-1001, comprises human MGE-type inhibitory GABAergic interneurons derived from pluripotent stem cells. NRTX-1001’s first indication is for the treatment of drug-resistant focal epilepsy, which is a major unmet need affecting approximately one-third of people living with epilepsy. The NRTX-1001 inhibitory neurons are targeted to the seizure-onset zone to enhance GABAergic inhibition, reduce seizure activity, and repair the affected neural network. NRTX-1001 is delivered as a single, one-time dose and is intended to persist and provide long-term seizure suppression. Currently, the drug is in Phase I/II stage of its clinical trial for the treatment of Drug-Resistant Refractory Epilepsy.

NPT 2042: NeuroPro Therapeutics, Inc.

NPT 2042, an orally administered adjunct treatment option for epilepsy patients who lack seizure control or who are unable to tolerate the side effects of their currently prescribed therapies. NPT 2042 is being developed as a chronic treatment to control the frequency and magnitude of seizure activity without the common side effects of current antiseizure medications (ASM). Currently, the drug is in Phase I stage of its clinical trial for the treatment of Drug-Resistant Refractory Epilepsy.
