24 Clinical Trials for Various Conditions
The investigators are collecting genetic information through blood samples as well as clinical and EEG data from over 1000 people with Juvenile Myoclonic Epilepsy (JME) across the UK, Europe and North America. This study will draw on both existing and new samples from JME patients. These will be compared to anonymised data from samples for 2000 controls. The goal of this study is to find the genetic cause of JME. Finding the cause will help create better treatments for JME, as well as improve patient outcomes by allowing us to detect it earlier.
Investigators at Boston Children's Hospital are conducting research in order to better understand the genetic factors which may contribute to epilepsy and related disorders. These findings may help explain the broad spectrum of clinical characteristics and outcomes seen in people with epilepsy.
This study will examine the effect of the newly developed anti-epileptic drug, levetiracetam, on excitability of the cortex (surface layer) of the brain. Levetiracetam works differently from other anti-seizure drugs, but its mechanism is not well understood. This study may provide insight into a new protection mechanism against seizures as well as the effect of the drug on cortical excitability. Healthy normal volunteers 18 years of age and older may be eligible for this study. Candidates will have a medical history taken and undergo physical and neurological examinations. Participants will undergo two different procedures in four separate sessions. One procedure (cortical excitability) involves taking either levetiracetam or placebo (a look-alike inactive substance) and having transcranial magnetic stimulation (TMS). The other procedure (pinch-training related changes) involves taking levetiracetam or placebo, doing a motor exercise called pinch training, and having transcranial magnetic stimulation. For TMS, a very brief electrical current is passed through an insulated coil wire placed on the scalp. The magnetic pulse travels through the scalp and skull, causing small electrical currents in the cortex that may cause muscle, hand, or arm twitching or it may affect movements or reflexes. During the study, subjects may be asked to make movements, do simple tasks or tense muscles. Electrical activity of the muscles will be recorded using electrodes taped to the skin over the muscle. For the pinch training, the subject makes a brief, brisk pinch after each beat of a metronome every two seconds and then completely relaxes the hand until the next beat. Subjects will be tested on four different days at least 72 hours apart. Each session will last about 3 to 4 hours. Approximate schedule for cortical excitability testing: TMS (study 1) Take levetiracetam or placebo TMS (study 2) \< 60 minutes after drug or placebo TMS (study 3) \< 120 minutes after drug or placebo Approximate schedule for pinch-training related changes: Take levetiracetam or placebo TMS and pinch power measurement \< 60 minutes after drug or placebo Pinch training for 30 minutes TMS and pinch power measurement Sample schedule: Session 1 \< LTC and cortical excitability testing Session 2 \< Placebo and cortical excitability testing Session 3 \< LTC and pinch-training related changes Session 4 \< Placebo and pinch-training related changes

The purpose of this study is to learn more about the medical problems and the genetic factors involved in a recently defined form of inherited dementia called "familial dementia with neuroserpin inclusion bodies (FDNIB)." Abnormal substances in nerve cells of patients with this disease affect brain and nervous system function, causing confusion, memory decline and impaired cognition (thinking ability). Patients also develop movement disorders and, possibly, seizures. Symptoms begin in midlife, between 45 and 55 years of age. Patients with FDNIB and family members 18 years of age or older at risk for the disease may be eligible for this 3-year study. Participants will have a medical and family history and review of medical records; interview with a medical geneticist (specialist in genetics); physical, neurological and psychiatric examinations; and the following tests and procedures: 1. Blood tests to assess general health 2. Chest and skull X-rays 3. Electrocardiogram (EKG)-record of the electrical activity of the heart using electrodes placed on the chest 4. Electroencephalogram (EEG)-record of the electrical activity of the brain using electrodes placed on the head 5. Ultrasound of the abdomen-imaging of abdominal organs using sound waves 6. Brain magnetic resonance imaging (MRI)-imaging of the brain using a strong magnetic field and radio waves 7. Hearing evaluation 8. Assessment of performance of daily living activities 9. Single photon emission computed tomography (SPECT)-imaging of brain metabolism and blood flow using a radioactive substance injected into a vein The evaluation will be done over a 3- to 4-day period. At their completion, participants will meet with a physician and a genetics counselor to discuss the clinically significant findings. Participants may be asked to return for follow-up evaluations every 6 months to a year (depending on the individual's condition) for 3 years.

Study 1 and Study 3 are the prospective, merged analyses of 2 identical double-blind, placebo-controlled studies, ZX008-1501 and ZX008-1502, to assess the efficacy, safety, and pharmacokinetics of ZX008 when used as adjunctive therapy in pediatric and young adult subjects with Dravet syndrome. Study 1501 and Study 1502 were conducted in parallel; Study 1501 was conducted at approximately 30 study sites in North America; Study 1502 was conducted at approximately 30 study sites in Europe, Asia and Australia. Upon completion of the Baseline Period after initial Screening and Baseline charting of seizure frequency, subjects who qualified for the studies were randomized (1:1:1) in a double-blind manner to receive either 1 of 2 doses of ZX008 (0.2 mg/kg/day or 0.8 mg/kg/day; maximum dose: 30 mg/day) or placebo. Randomization was stratified by age group (\< 6 years, ≥6 to 18 years) to achieve balance across treatment arms, with the target of 25% of subjects in each age group. All subjects were titrated to their randomized dose over a 14-day Titration Period. Following titration, subjects continued treatment at their randomly assigned dose over a 12-week Maintenance Period. Subjects exiting the study underwent a 2-week taper, unless they enrolled in a follow-on study. Subjects were followed for post-study safety monitoring.
