Filter by:This is an intermediate-size expanded access program (EAP) study. The purpose of this EAP is to provide continued access to LP352, an investigational drug product being investigated in patients with Developmental and Epileptic Encephalopathies (DEEs). The EAP study will allow continued treatment with LP352 for eligible patients diagnosed with treatment resistant DEEs who successfully completed an LP352 Clinical Trial (Enrollment by Invitation).
The main aims of this study are to gather information about how many children, teenagers and adults in Spain have been diagnosed with Dravet syndrome and Lennox-Gastaut syndrome as well as to learn about the number of new Dravet syndrome and Lennox-Gastaut syndrome cases in persons in Spain. Participants' data will be taken from their medical records (charts), which were already collected as a part of their routine care in public hospitals in Spain between 01 January 2021 and 31 December 2022.
The objective of this study is to assess the long-term safety, tolerability, and efficacy of adjunctive therapy of LP352 in subjects with developmental and epileptic encephalopathies who completed participation in Study LP352-201.
This is a prospective, observational study on approximately 70 Real World participants affected by LGS or DS, treated with Epidyolex® as prescribed in the summary of product characteristics. The eligible participants are expected to participate in the study for a duration of 56 weeks of treatment.
The CADET Pilot will investigate the safety and feasibility of deep brain stimulation (DBS) to treat children with Lennox-Gastaut syndrome using a novel DBS device (Picostim DyNeuMo-1). Following a 30-day preoperative/baseline assessment phase, all children will have a neurosurgical procedure to implant the device. Implantation will be followed by a 30-day phase of no stimulation (the device is off / inactive) and then a six-month phase of active stimulation (the device is on / active).
Lennox-Gastaut syndrome is a serious and rare form of epilepsy that begins in infancy and early childhood. Seizures and their consequences need medical attention, emergency encounters, and hospitalizations. Seizures disrupt home life for the patient and for family. Lennox-Gastaut syndrome is typically accompanied by disabilities in motor, communication, eating, and other skills needed for daily function. Lennox-Gastaut syndrome (LGS) has no cure. Although current treatments may help reduce the number of seizures, none are expected to eliminate them entirely; these treatments are palliative. The main treatments include anti-seizure medications and some surgical approaches, including the implantation of a vagus nerve stimulator (a pacemaker-like generator implanted in the chest wall and programmed by a physician to stimulate the vagus nerve in the neck) and corpus callosotomy (cutting through the band of fibers that connect the two sides of the brain). While both types of treatment (medications and surgeries) produce some benefit by reducing how often the seizures occur, both also have some risks. All medications can, in some patients, produce moderate to severe side effects. This is true of anti-seizure medications. Most patients with LGS take several anti-seizure medications at a time. Surgeries can also have associated risks and is additionally stressful for parents and family members. Currently, there is no strong evidence to support parents and physicians in deciding which type of treatment (more medicines or surgery) will be most successful for a child with LGS, and whether one or the other approach may lessen the toll that seizures take on a child's development and ability to function. This study has two components. It will engage a network of seven pediatric hospitals in the United States where children with Lennox-Gastaut syndrome are cared for and determine whether seizure-related emergency department visits and hospitalizations are more likely to be reduced following the use of additional medications or adding palliative surgery to existing medications. The investigators will determine whether medical versus surgical treatment is more likely to lessen some of the developmental and functional difficulties that affect patients with LGS. The study will also determine whether starting therapies at a younger versus older age makes a difference. The second component of the study will provide a description of the use of surgical versus medical treatment approaches across 18 pediatric hospitals in the United States (seven plus 11 centers). The investigators will describe how treatments differ across hospitals and over time. The results from this study will help parents and providers make more informed choices about treatment for children with Lennox-Gastaut syndrome and will highlight areas for improvement in providing the best possible health care for this severe, lifelong disorder.
The objective of this study is to assess the safety, tolerability, efficacy, and pharmacokinetics of adjunctive therapy of LP352 in adults and adolescents with developmental and epileptic encephalopathies.
To generate preliminary safety and effectiveness data for brain-responsive neurostimulation of thalamocortical networks as an adjunctive therapy in reducing the frequency of generalized seizures in individuals 12 years of age or older with Lennox Gastaut Syndrome (LGS) who are refractory to antiseizure medications. The intent is to determine the feasibility and the optimal design of a subsequent pivotal study in order to expand the indication for use for the RNS System as a treatment for patients with medically intractable LGS.
The primary objective is to evaluate the efficacy of carisbamate (YKP509) as adjunctive treatment in reducing the number of drop seizures (tonic, atonic, and tonic-clonic) compared with placebo in pediatric and adult subjects (age 4-55 years) diagnosed with Lennox Gastaut Syndrome (LGS).
The main aim of the study is to learn if soticlestat, when given as an add-on therapy, reduces the number of seizures in children and adults with Dravet Syndrome (DS) or Lennox-Gastaut Syndrome (LGS). Participants will receive their standard anti-seizure therapy, plus tablets of soticlestat. There will be scheduled visits and follow-up phone calls throughout the study.
