17 Clinical Trials for Various Conditions
The purpose of the study is to evaluate the change in visual fields by means of automated static perimetry and to evaluate the change in retinal structure by means of spectral domain optical coherence tomography (SD-OCT) in adult patients with refractory complex partial seizures (CPS) being treated with vigabatrin (Sabril®)
This is an open-label, phase 4 study to examine the safety and efficacy of vigabatrin (Sabril) in Tuberous Sclerosis patients, a subset of the larger refractory complex partial epilepsy population for which the drug is approved. While enrolled on this trial, subjects will continue to take all of their normally prescribed medications, including their other antiepileptic drugs (AEDs). Alternatively, there is a prospective observational arm that subjects who are about to take Sabril as treatment for seizures associated with Tuberous Sclerosis may join. Subjects who join this arm will not have any study visits and will not be asked to do anything specifically for the study. The study team will collect all study data from subjects' medical records only.
This is a two-part study that aims to determine the reliability and safety of the use of the Hövding inflatable helmet in seizures, as evidenced by the deployment of the helmet during seizures, and qualitative patient reporting.
A follow-on, two-year open-label extension study of ganaxolone as add-on therapy in adult patients with drug-resistant partial-onset seizures
The study will evaluate the effectiveness and safety of an investigational drug-ganaxolone - on partial seizure frequency in adults with epilepsy taking a maximum of 3 antiepileptic medications (AEDs).
The study will evaluate the effectiveness and safety of an investigational drug-ganaxolone - on partial seizure frequency in adults with epilepsy taking a maximum of 3 antiepileptic medications (AEDs). The study will also evaluate the effectiveness of ganaxolone in females with catamenial epilepsy. Catamenial epilepsy refers to a relationship between seizure frequency and a woman's menstrual cycle, where the number of seizures increases around the time of a woman's menstrual cycle.
The purpose of this study is to evaluate the safety and tolerability of long-term therapy with retigabine administered as adjunctive therapy in adult epilepsy patients with partial-onset seizures, who completed the VRX-RET-E22-301 double-blind study. The efficacy of long-term treatment with retigabine and patient quality of life will also be assessed.
This Phase 3 study is being conducted to evaluate the efficacy and safety of retigabine dosed at 900 mg/day and 600 mg/day, in three equally divided doses, compared with placebo in patients with epilepsy who are receiving up to three established antiepileptic drugs (AEDs).
This Phase 3 study is being conducted to evaluate the efficacy and safety of retigabine dosed at 1200 mg/day, in three equally divided doses, compared with placebo in patients with epilepsy who are receiving up to three established antiepileptic drugs (AEDs).
The purpose of this study is to determine whether zonisamide alone is effective as a treatment for epilepsy in newly diagnosed cases.
This study will measure and compare hormone levels in women with catamenial epilepsy (epilepsy in which seizures are more frequent during menstrual periods), women with seizures not related to their menstrual cycle, and normal control subjects. It will determine whether there are differences among the three groups in their hormone levels or in how fast the levels change. It will also examine what relationship, if any, exists between hormone changes and seizures in women with catamenial epilepsy. The hormones under study include the gonadal hormones estrone, estradiol and progesterone, and the neuroactive steroids allopregnanolone, pregnenolone, and dehydroepiandrosterone. Women who meet the following criteria may be eligible for this 3-month study: * Between 18 and 45 years of age, with catamenial epilepsy * Between 18 and 45 years of age, with seizures, but not catamenial epilepsy * Between 18 and 45 years of age, without seizures All participants will have a physical examination at the beginning of the study, at each clinic visit, and at completion or withdrawal from the study. In addition, they will undergo the following procedures: Baseline Monitoring For the first 2 months, all participants will keep a diary of their temperature and onset of menses. Women with epilepsy will also record their seizures. Electroencephalography (EEG) Healthy volunteers will have a 45-minute EEG (recording of the electrical activity of the brain) at the beginning of each menstrual cycle and each day during the menses. Women with epilepsy will have continuous EEG monitoring for 8 days, beginning 5 days before their menstrual period is expected. The continuous monitoring can be done on an outpatient basis, using a portable EEG recording device, or as an inpatient, with admission to the hospital for the 8 days of recording. Blood Sampling All participants will have a small blood sample (2 teaspoons) drawn once a day on days 10, 14, 17, 19 and 21 of their menstrual cycle and three times a day on day 6 and for a period of 8 days, starting 5 days before the expected menses and continuing for 3 days of the next cycle. For the days with three blood draws, a small needle that can stay in place for up to 72 hours will be placed in the arm to avoid the discomfort of multiple needle sticks.
This protocol has three purposes: 1) to screen patients with seizures for participation in research studies of NINDS s Clinical Epilepsy Section (CES), 2) to follow the natural course of seizure disorders, and 3) to train CES fellows in evaluating and treating epilepsy. Only standard diagnostic tests and treatments will be used in this study. Patients of any age with seizures who are referred to CES may participate in this study. At the end of the study, patients may be discharged to the care of their referring physician, offered participation in another NINDS research protocol, or followed for teaching purposes. Participants will undergo standard diagnostic procedures used to determine the type of their seizures, what part of the brain they are coming from, what is causing them, and whether standard drug treatments can help them. These may include some or all of the following: * Physical and neurological examination * Neuropsychological tests tests of learning and memory * Electroencephalography (EEG) brain wave recording * Evoked potentials tests of nerve reactions to lights and sounds * Polysomnography simultaneous recordings of brain waves, breathing and eye movements * Video-EEG monitoring simultaneous recording of seizures using a video camera and brain waves * Video-EEG monitoring with extra electrodes to record muscle activity, breathing and eye movements for analyzing sleep patterns * Imaging studies, such as magnetic resonance imaging (MRI) and positron emission tomography (PET) scans to examine the structure and function of the brain * Frequent blood tests to measure blood levels of anti-seizure drugs
This study is designed to test the effects of vigabatrin (gamma-vinyl-GABA) an experimental drug used for the treatment of epilepsy. The study will use positron emission tomography (PET scan) to detect areas of the brain receiving increased blood flow and using increased amounts of glucose. Increases in blood flow and glucose use are good indicators of brain activity. Researchers are interested in determining the effects of Vigabatrin on brain blood flow and glucose use.
This is an 18-week, double-blind, multicenter study with gradual conversion from previous antiepileptic therapy to eslicarbazepine acetate monotherapy in subjects with partial epilepsy.
This study evaluated the efficacy and safety of two trough-ranges of everolimus given as adjunctive therapy in patients with tuberous sclerosis complex (TSC) who had refractory partial-onset seizures. The study consisted of 4 phases for each patient Baseline phase:\[From Screening Week -8 (V1) to randomization visit at Week 0 (V2)\], Core phase \[from randomization at Week 0 (V2) to Week 18 (V11)\], Extension phase \[from Week 18 (V11) until 48 weeks after the last patient had completed the core phase\] and Post Extension phase \[from end of Extension phase to end of study\].
To evaluate the efficacy and safety of diazepam in the management of refractory epilepsy in selected patients who require intermittent medical intervention for the control of episodes of acute repetitive seizures. In addition, to assess the support provided by caregivers who are not themselves or not under the direct supervision of health care professionals at the time of administration.
This study is designed to provide ganaxolone to those patients deriving significant benefit from current treatment in protocol 1042-0601.
