Dravet Syndrome: Understanding

Dravet Syndrome: Overview

Dravet Syndrome is a severe and progressive genetic epilepsy characterized by frequent, prolonged, and refractory seizures that usually begin within the first year of life. Dravet Syndrome is classified as a developmental and epileptic encephalopathy due to the developmental delays and cognitive impairment, in addition to seizure activity, that stem from the genetic mutation that causes the disease. The voltage-gated sodium channel is responsible for the initiation of action potentials and, therefore, is involved in neuronal excitability. The alpha subunit has four homologous domains with six transmembrane segments each that form the voltage sensor and ion-conducting pore. Mutations cause either a gain or a loss of function. Initially, researchers could not explain how loss-of-function mutations could lead to seizures. A mouse model of DS showed selective loss of sodium current in the hippocampal ?-aminobutyric acid-mediated inhibitory interneurons. Failure of inhibition leading to excitation is a proposed pathogenesis of this mutation in DS.

Approximately 85% of those diagnosed with Dravet Syndrome have a mutation of the SCN1A gene. Dravet Syndrome is not usually caused by an inherited mutation. In 90% of these patients, the mutation is not found in the patient’s parents Dravet Syndrome can be diagnosed, if a patient exhibits specific symptoms, genetic testing may be done via an epilepsy panel, to look for SCN1A and other genes commonly associated with epilepsy. However, the effects of Dravet syndrome are not limited to seizures, developmental delays, movement and balance issues and also language and speech disturbances. Dravet syndrome has a high rate of premature death due to the severity of this type of epilepsy. Up to 20% of children and adolescents living with Dravet die before adulthood.

The correct diagnosis of DS and appropriate follow-up are typically delayed. The EEG is normal at onset, and neuroimaging reveals no structural lesion. Early development is normal, but signs of regression appear in the second year of life and are often accompanied by convulsive status epilepticus, alternating hemiconvulsions, and myoclonic seizures. The diagnosis can be confirmed by genetic testing that is now available and shows mutations within the SCN1A gene. Early recognition and diagnosis of DS and management with appropriate anticonvulsants and a treatment plan may reduce the seizure burden and improve the long-term developmental outcome.

Dravet Syndrome Emerging Drugs Chapters

This segment of the Dravet Syndrome report encloses its detailed analysis of various drugs in different stages of clinical development, including phase II, I, preclinical and Discovery. It also helps to understand clinical trial details, expressive pharmacological action, agreements and collaborations, and the latest news and press releases.

Dravet Syndrome Emerging Drugs

Soticlestat : TakedaSoticlestat is a potent, highly selective, oral, first-in-class inhibitor of the enzyme cholesterol 24-hydroxylase (CH24H), with the potential to reduce seizure susceptibility and improve seizure control. CH24H is predominantly expressed in the brain, where it converts cholesterol into 24S-hydroxycholesterol (24HC) to adjust the homeostatic balance of brain cholesterol. 24HC is a positive allosteric modulator of the NMDA receptor and modulates glutamatergic signaling associated with epilepsy. Glutamate is one of the main neurotransmitters in the brain and has been shown to play a role in the initiation and spread of seizure activity. Recent literature indicates that CH24H is involved in over-activation of the glutamatergic pathway through modulation of the NMDA channel and that increased expression of CH24H can disrupt the reuptake of glutamate by astrocytes, resulting in epileptogenesis and neurotoxicity. Inhibition of CH24H by soticlestat reduces the neuronal levels of 24HC and may improve the excitatory/inhibitory balance of NMDA channel activity. It is being investigated by Ovid and Takeda for the treatment of rare developmental and epileptic encephalopathies (DEEs), a group of highly refractory epilepsy syndromes including Dravet Syndrome and LGS. Soticlestat is in the Phase III stage of development for the treatment of Dravet Syndrome.

STK-001: Stoke TherapeuticsSTK-001 is an investigational new medicine for the treatment of Dravet syndrome. It is a proprietary antisense oligonucleotide (ASO) and has the potential to be the first disease-modifying therapy to address the genetic cause of Dravet syndrome. The drug is designed to upregulate NaV1.1 protein expression by leveraging the non-mutant copy of the SCN1A gene to restore physiological NaV1.1 levels, thereby reducing both the occurrences of seizures and significant non-seizure comorbidities. This RNA-based approach is not gene therapy but rather RNA modulation, as it does not manipulate nor insert genetic deoxyribonucleic acid (DNA). The drug is currently in Phase II clinical trial for the treatment of patients with Dravet Syndrome.

LP352: Longboard PharmaceuticalsLP352 is an oral, centrally acting 5-HT2c superagonist in development for the potential treatment of seizures associated with DEEs such as Dravet syndrome, LGS, tuberous sclerosis complex (TSC), CDKL5 deficiency disorder (CDD), and other epileptic disorders. LP352 is designed to modulate GABA and, as a result, suppress the central hyperexcitability that is characteristic of seizures. LP352 is the only 5-HTc receptor superagonist being dose-optimized for the refractory epilepsy population. LP352 also demonstrated statistically significant reductions in both epileptiform event frequency and duration - reducing the frequency of epileptiform events by 85% and the cumulative duration of epileptiform events by 84% in the SCN1lab zebrafish model of Dravet syndrome.
