Active clinical trials for "Lennox Gastaut Syndrome"

The purpose of this study is to evaluate the safety and efficacy of clobazam as adjunctive therapy in the treatment of seizures which lead to drop attacks (drop seizures) in patients 2 to 60 years of age with Lennox-Gastaut Syndrome (LGS). Patients will be enrolled at approximately 65 sites in the U.S. and ex-US for up to 23 weeks. Patients will be randomly assigned to either a low, medium or high dose, or placebo. The study will include a baseline period, a titration period and a maintenance period. After the maintenance period, patients will either continue into an open-label extension study or enter the taper period with a final visit 1 week after the last dose.

The purpose of this study is to evaluate the effectiveness and safety of topiramate as add-on therapy in the treatment of epilepsy patients with Lennox-Gastaut syndrome, a severe form of epilepsy in which there are mixed types of seizures.

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 evaluate the long-term safety and effectiveness of open-label clobazam in the treatment of drop seizures in subjects with LGS.

The primary objective of this study was to evaluate the efficacy of GWP42003-P as adjunctive treatment in reducing the number of drop seizures when compared with placebo in participants with Lennox-Gastaut syndrome (LGS).

To investigate the safety of long term administration of E2080 in the patients with Lennox-Gastaut syndrome who completed the E2080-J081-304 Study.

To confirm that the combination therapy of rufinamide has superior efficacy compared to placebo in patients with Lennox-Gastaut syndrome.

The purpose of this study is to evaluate the safety and efficacy of clobazam as adjunctive therapy in the treatment of seizures which lead to drop attacks (drop seizures) in subjects 2 to 30 years of age with Lennox-Gastaut Syndrome (LGS). Subjects will be enrolled at approximately 10 investigational sites in the U.S. for up to 15 weeks. Subjects will be randomly assigned to either a low dose or a high dose. The study will include a baseline period, a titration period and a maintenance period. After the maintenance period, subjects will either continue into an open-label extension study or enter the taper period with a final visit 1 week after the last dose.

The investigators propose to study the effects of cannabidiol (CBD) on cardiac electrical function and the autonomic nervous system in children with Dravet syndrome (DS) and Lennox-Gastaut syndrome (LGS), when the CBD is administered as an artisanal oil obtained through state dispensaries or other sources. The intent is to begin to assess potential risks and benefits of this therapy in a vulnerable patient population by characterizing the effects of CBD on EKG findings, heart rate variability and the occurrence of seizures.

Background: Lennox-Gastaut syndrome (LGS) is a severe childhood epileptic syndrome with high pharmacoresistance. The treatment outcomes are still unsatisfied. The investigator previous study of cathodal transcranial direct current stimulation (tDCS) in children with focal epilepsy showed significant reduction in epileptiform discharges. The investigator hypothesized that cathodal tDCS when applied over the primary motor cortex (M1) combined with pharmacologic treatment will be more effective for reducing seizure frequency in participants with LGS than pharmacologic treatment alone. Material and Method: Study participants were randomized to receive either: pharmacologic treatment with 5-consecutive days of 2 milliampere (mA) cathodal tDCS over M1 for 20 min or pharmacologic treatment plus sham tDCS. Measures of seizure frequency and epileptic discharges were performed before treatment and again immediately post-treatment and 1-, 2-, 3-, and 4-week follow-up.
