Newest firstObjectives Dravet syndrome (DS) is a drug-resistant developmental and epileptic encephalopathy, often requiring three or more antiseizure medications (ASMs). Consequently, the therapeutic landscape is highly complex, combining DS-specific agents (stiripentol, STP; cannabidiol, CBD; fenfluramine, FFA), non-specific ASMs, and non-pharmacologic options such as dietary therapy or neuromodulation. In addition, recognit…
Open article record in new tab ↗Voltage-gated sodium channels are essential ionic-conductance pathways in the nervous system, which play an irreplaceable role in modulating neuronal excitability and signal transduction. This review comprehensively analyzes the molecular mechanisms and pathophysiological significance of voltage-gated sodium channels, with particular emphasis on elucidating the molecular-action mechanisms of the distinct subtypes…
Background/Objectives: Dravet Syndrome (DS) is a severe form of epilepsy that typically manifests in the first year of life and often requires polytherapy with two or more antiseizure medications (ASMs) to achieve adequate seizure control. Whereas the combination of stiripentol (STP) and cannabidiol (CBD) has demonstrated clinical efficacy, it presents significant formulation challenges due to the low aqueous solu…
SCN1A -related disorders are the single most common monogenic cause of epilepsy and represent a major focus of precision medicine efforts. In conjunction with existing prospective studies, the analysis of real-world data obtained during routine clinical care can expand upon the scale and duration of available data and contribute to the development of meaningful outcomes for clinical trials. Here, we leveraged real…
Dravet syndrome (DS) is a rare and severe form of epilepsy, characterised by recurrent seizures that begin during the first year of life, leading to motor, cognitive and behavioural impairments. This article provides the perspectives of a parent of a child with DS ('Ethan') and the treating neuropaediatrician. Ethan's seizures began when he was 9 months old, and were a mixture of focal seizures and status epilepti…
Open article record in new tab ↗Introduction Effectiveness and tolerability of plant-derived highly purified cannabidiol (CBD) in patients with Lennox-Gastaut syndrome (LGS), Dravet syndrome (DS), or tuberous sclerosis complex (TSC)-associated epilepsy in clinical practice in Germany were evaluated. Methods This multicenter, retrospective, chart review study analyzed patients with LGS, DS, or TSC-associated epilepsy receiving ≥ 1 dose of adjunct…
Background Highly purified Cannabidiol (CBD, epidiolex) is approved for treating Lennox-Gastaut syndrome (LGS), Dravet syndrome (DS), and tuberous sclerosis (TSC), with off-label use in drug-resistant epilepsies. The aim of this study is to evaluate efficacy, safety, and long-term retention of CBD in a large pediatric population. Methods We prospectively included all consecutive patients initiating CBD for drug-re…
Background Dravet syndrome is a severe epilepsy disorder characterized by drug-resistant seizures and cognitive dysfunction, often caused by SCN1A gene mutations. It leads to neurodevelopmental delays and motor, behavioral, and cognitive impairments, with a high mortality rate. Treatment options include sodium valproate, clobazam, and newer agents such as cannabidiol and fenfluramine. Zonisamide, which is used in…
Objectives Stiripentol, fenfluramine, and cannabidiol are licensed add-on therapies to treat seizures in Dravet Syndrome (DS). There are no direct or indirect comparisons assessing their full licensed dose regimens, across different jurisdictions, as first-line add-on therapies in DS. Methods We conducted a systematic review and frequentist network meta-analysis (NMA) of randomized controlled trial (RCT) data for…
Open article record in new tab ↗Background Dravet Syndrome (DS) is a rare and severe form of childhood epilepsy that is often refractory to conventional antiepileptic drugs. Emerging evidence suggests that Cannabidiol (CBD) offer therapeutic benefits for DS. This review aims to evaluate the efficacy and safety of CBD in pediatric patients with DS based on data from ten clinical trials. Methods A review was conducted to identify clinical trials a…
Dravet Syndrome (DS) is a developmental epileptic encephalopathy characterized by drug-resistant seizures and other clinical features, including intellectual disability and behavioral, sleep, and gait problems. The pathogenesis is strongly connected to voltage-gated sodium channel dysfunction. The current consensus of seizure management in DS consists of a combination of conventional and recently approved drugs su…
Open article record in new tab ↗Dravet syndrome is a severe developmental and epileptic encephalopathy mostly caused by heterozygous mutation of the SCN1A gene encoding the voltage-gated sodium channel α subunit Nav1.1. Multiple seizure types, cognitive deterioration, behavioral disturbances, ataxia, and sudden unexpected death associated with epilepsy are a hallmark of the disease. Recently approved antiseizure medications such as fenfluramine…
Background: T-type Ca2+ channels (Cav3) represent emerging therapeutic targets for a range of neurological disorders, including epilepsy and pain. To aid the development and optimisation of new therapeutics, there is a need to identify novel chemical entities which act at these ion channels. A number of synthetic cannabinoid receptor agonists (SCRAs) have been found to exhibit activity at T-type channels, suggesti…
Introduction: The cannabinoid Δ9-tetrahydrocannabinolic acid (Δ9-THCA) has long been suggested in review articles and anecdotal reports to be anticonvulsant; yet, there is scant evidence supporting this notion. The objective of this study was to interrogate the anticonvulsant potential of Δ9-THCA in various seizure models-the Scn1a+/- mouse model of Dravet syndrome, the 6-Hz model of psychomotor seizures and the m…
Open article record in new tab ↗Purpose: Recently, the U.S. Food and Drug Administration (FDA) approved stiripentol, cannabidiol, and fenfluramine to treat patients with Dravet syndrome (DS). Moreover, soticlestat was determined as a promising new drug for the treatment of DS as it has good efficacy and safety. However, the efficacy and safety of these drugs have not yet been evaluated in "head-to-head" trials. This study aimed to compare and ev…
Open article record in new tab ↗Objective Cannabigerolic acid (CBGA), a precursor cannabinoid in Cannabis sativa, has recently been found to have anticonvulsant properties in the Scn1a+/- mouse model of Dravet syndrome. Poor brain penetration and chemical instability of CBGA limits its potential as an anticonvulsant therapy. Here, we examined whether CBGA methyl ester, a more stable analogue of CBGA, might have superior pharmacokinetic and antic…
Dravet syndrome (DS) is a channelopathy, neurodevelopmental, epileptic encephalopathy characterized by seizures, developmental delay, and cognitive impairment that includes susceptibility to thermally induced seizures, spontaneous seizures, ataxia, circadian rhythm and sleep disorders, autistic-like behaviors, and premature death. More than 80% of DS cases are linked to mutations in genes which encode voltage-gate…
Open article record in new tab ↗Voltage-gated sodium (Nav) channels initiate action potentials in excitable tissues. Altering these channels' function can lead to many pathophysiological conditions. Nav channels are composed of several functional and structural domains that could be targeted pharmacologically as potential therapeutic means against various neurological conditions. Mutations in Nav channels have been suggested to underlie various…
Open article record in new tab ↗Background: Purified cannabidiol (CBD) was administered to highly refractory patients with Dravet (DS) or Lennox-Gastaut (LGS) syndromes in an ongoing expanded access program (EAP). Herein, we report interim results on CBD safety and seizure outcomes in patients treated for a 12-month period. Material and Methods: Thirty centers were enrolled from December 2018 to December 2019 within the open-label prospective EA…
Open article record in new tab ↗Background and Aim: Data on the clinical pharmacokinetics of cannabidiol (CBD) are scanty. We explored the effect of demographic and clinical variables on plasma concentrations of purified CBD in patients with Dravet (DS) and Lennox-Gastaut syndrome (LGS). Methods: The study design was an open, prospective, multicenter expanded access program (EAP). Venous blood samples were drawn from patients between 8 and 9 am,…
