The contribution of fenfluramine to the treatment of Dravet syndrome in Spain through Multi-Criteria Decision Analysis

Introduction: Dravet Syndrome (DS) is a severe, developmental epileptic encephalopathy (DEE) that begins in infancy and is characterized by pharmaco-resistant epilepsy and neurodevelopmental delay. Despite available antiseizure medications (ASMs), there is a need for new therapeutic options with greater efficacy in reducing seizure frequency and with adequate safety and tolerability profiles.Fenfluramine is a new ASM for the treatment of seizures associated with DS as add-on therapy to other ASMs for patients aged 2 years and older. Fenfluramine decreases seizure frequency, prolongs periods of seizure freedom potentially helping to reduce risk of Sudden Unexpected Death in Epilepsy (SUDEP) and improves patient cognitive abilities positively impacting on patients' Quality of Life (QoL).Reflective Multi-Criteria Decision Analysis (MCDA) methodology allows to determine what represents value in a given indication considering all relevant criteria for healthcare decision-making in a transparent and systematic manner from the perspective of relevant stakeholders. The aim of this study was to determine the relative value contribution of fenfluramine for the treatment of DS in Spain using MCDA.Method: A literature review was performed to populate an adapted a MCDA framework for orphan-drug evaluation in Spain. A panel of ten Spanish experts, including neurologists, hospital pharmacists, patient representatives and decision-makers, scored four comparative evidence matrices.Results were analyzed and discussed in a group meeting through reflective MCDA discussion methodology. Results: Dravet syndrome is considered a severe, rare disease with significant unmet needs. Fenfluramine is perceived to have a higher efficacy profile than all available alternatives, with a better safety profile than stiripentol and topiramate and to provide improved QoL versus studied alternatives. Fenfluramine results in lower other medical costs in comparison with stiripentol and clobazam. Participants perceived that fenfluramine could lead to indirect costs savings compared to available alternatives due to its efficacy in controlling seizures. Overall, fenfluramine's therapeutic impact on patients with DS is considered high and supported by high-quality evidence.Conclusions: Based on reflective MCDA, fenfluramine is considered to add greater benefit in terms of effi-cacy, safety and QoL when compared with available ASMs.(c) 2022 The Authors.

Enhancing Executive Functions in Pediatric Epilepsy: Feasibility and Efficacy of a Computerized Cognitive Training Program

Epilepsy, a prevalent neurological disorder characterized by recurrent seizures, significantly impacts individuals’ neurobiological, cognitive, and social lives. This report presents a feasibility study investigating the effects of a computerized cognitive training program on enhancing executive functions, particularly inhibitory control, in children and adolescents with epilepsy. Employing a pre-test–intervention–post-test design, the study involved 26 participants with diverse epileptic syndromes, focusing on those without severe intellectual disabilities. The intervention, based on the CogniFit Inc. platform, consisted of personalized tasks aiming to improve participants’ inhibitory skills over 16 weeks, with an average of 40 sessions completed per participant. Results indicated significant improvements in reaction times and error rates in an anti-saccade task, demonstrating enhanced inhibitory control and general performance post-intervention. These findings suggest that targeted cognitive training is a feasible approach to bolster executive functions in young individuals with epilepsy, potentially improving their academic performance, employability, and social interactions. The study underscores the importance of early cognitive interventions in epilepsy management, highlighting the potential for computerized programs to aid in mitigating cognitive deficits associated with the condition

The psychosocial impact of caring for children with Dravet Syndrome

This study examined the psychosocial impact on parents of children affected by Dravet Syndrome (DS), a rare drug-resistant developmental encephalopathic epileptic syndrome which affects children at an early age and that involves severe cognitive, behavioral, and motor impairments. DS has a major negative impact on caregivers, mainly on their physical and mental health, and on their social relationships and economic resources. Similarly, it has been suggested that the quality of life of caregivers and children with DS is lower compared to the general population, especially because of the severe and frequent seizures suffered by the child, leaving caregivers with heavy burdens. The main aim of the current study was to assess in detail the psychosocial impact that having a child with DS represents for their parents or caregivers. To this end, a standardized assessment tool was used, and the results were compared to those of a control group. The results highlighted critical differences in most of the areas explored, revealing a marked difference between parents caring of children with DS and parents of normotypically developing children in the psychosocial wellness. This study provides important qualitative data to help us understand and identify the complexity of DS

Validation of Childhood Rare Epilepsy Social Impact Assessment (CRESIA) to Measure the Social and Family Impact of Rare Childhood Diseases with Epilepsy

This study addresses the social relevance of low-prevalence childhood diseases and reports the process of generation and validation of a tool to assess the social impact on the direct family environment and the social context of reference. The aim of the process of construction and validation of this instrument is to provide the field with a tool with the capacity to shed light on the social consequences of suffering from a low-prevalence disease, specifically those comorbid with treatment-resistant epileptic seizures of childhood origin. The instrument here presented and called CRESIA (acronym derived from Childhood Rare Epilepsy Social Impact Assessment) provides valuable information on six specific areas framing health, economic, psychological, social, and child-related stressors, as well as family. CRESIA represents a valid and reliable instrument for family members or primary caregivers of children and adolescents with childhood rare epilepsy

The Charlotte Project: Recommendations for patient-reported outcomes and clinical parameters in Dravet syndrome through a qualitative and Delphi consensus study

Objective: The appropriate management of patients with Dravet Syndrome (DS) is challenging, given the severity of symptoms and the burden of the disease for patients and caregivers. This study aimed to identify, through a qualitative methodology and a Delphi consensus-driven process, a set of recommendations for the management of DS to guide clinicians in the assessment of the clinical condition and quality of life (QoL) of DS patients, with a special focus on patient- and caregiver-reported outcomes (PROs). Methods: This study was conducted in five phases, led by a multidisciplinary scientific committee (SC) including pediatric neurologists, epileptologists, a neuropsychologist, an epilepsy nurse, and members of DS patient advocates. In phases 1 and 2, a questionnaire related to patients’ QoL was prepared and answered by caregivers and the SC. In phase 3, the SC generated, based on these answers and on a focus group discussion, a 70-item Delphi questionnaire, covering six topic categories on a nine-point Likert scale. In phase 4, 32 panelists, from dierent Spanish institutions and with a multidisciplinary background, answered the questionnaire. Consensus was obtained and defined as strong or moderate if ≥80% and 67–79% of panelists, respectively, rated the statement with ≥7. Phase 5 consisted of the preparation of the manuscript. Results: The panelists agreed on a total of 69 items (98.6%), 54 (77.14%), and 15 (21.43%) with strong and moderate consensus, respectively. Frontiers in Neurology 01 frontiersin.or Aledo-Serrano et al. 10.3389/fneur.2022.975034 The experts’ recommendations included the need for frequent assessment of patient and caregivers QoL parameters. The experts agreed that QoL should be assessed through specific questionnaires covering dierent domains. Likewise, the results showed consensus regarding the regular evaluation of several clinical parameters related to neurodevelopment, attention, behavior, other comorbidities, and sudden unexpected death in epilepsy (SUDEP). A consensus was also reached on the instruments, specific parameters, and caregivers’ education in the routine clinical management of patients with DS. Conclusions: This consensus resulted in a set of recommendations for the assessment of clinical and QoL parameters, including PROs, related to the general evaluation of QoL, neurodevelopment, attention, behavior, other comorbidities aecting QoL, SUDEP, and QoL of caregivers/relatives and patients with D
