The purpose of this study is to demonstrate that RWJ-333369 is safe and effective as add-on treatment of partial onset seizures.
According to the World Health Organization (WHO), epilepsy afflicts more than 50 million people worldwide. Despite the ongoing use of older antiepileptic drugs (AEDs) and the development of newer treatments that are better tolerated, approximately 30% of patients, particularly those with partial seizures, are not well controlled even on newer treatments, or experience significant side effects from treatment. RWJ-333369 is a drug with anticonvulsant activity that is being investigated for the treatment of epilepsy. This is a randomized (patients are assigned different treatments based on chance), double-blind study (neither the patient nor the physician knows whether drug or placebo is being taken, or at what dosage ) in males and females who have partial onset seizures that have had an inadequate response to at least one AED. The study consists of 3 phases: pretreatment (a screening visit and a 56-day baseline period), double-blind treatment (12 weeks of treatment with either 200 mg per day of RWJ-333369, 400 mg per day of RWJ-333369, or placebo), and posttreatment (a posttreatment visit that occurs 7 to 14 days after the last dose of double-blind study drug). The posttreatment phase is only for patients not continuing in the open-label extension study. The open-label extension study is offered after completion of the double-blind treatment phase if the study doctor judges that the patient may benefit from continued treatment with RWJ-333369. The open-label extension study lasts until RWJ-333369 becomes available by prescription or its development is stopped by the sponsor. The efficacy of the RWJ-333369 will be based on a change in the frequency and severity of seizures. Safety assessments include adverse events (side effects) reporting, collecting blood tests and Electrocardiograms and performing physical exams, including vitals signs. The study hypothesis is that 400 mg per day of RWJ-333369 is better than placebo as add-on treatment of partial onset seizures, as measured by the percent reduction from baseline in the monthly partial onset seizure frequency. 200 mg per day RWJ-333369, 400 mg per day RWJ-333369, or placebo, given twice daily with or without food approximately 12 hours apart; study drug should be swallowed whole and not be chewed, divided, crushed, or dissolved.

Progressive myoclonic epilepsy (PME) is rare epilepsy syndrome. Although EEG is a useful neurophysiological technique in the evaluation of epilepsy, few EEG abnormalities have been described in PME. S...
In the present study, we aimed to investigate patient-derived epilepsy-related concerns among Chinese individuals with epilepsy and the impact of seizure control on patient concerns.
Juvenile myoclonic epilepsy (JME) is an epileptic syndrome often regarded as one in which seizures are relatively easy to control. Individuals with JME, however, often require lifelong therapy to rema...
A disorder characterized by the onset of myoclonus in adolescence, a marked increase in the incidence of absence seizures (see EPILEPSY, ABSENCE), and generalized major motor seizures (see EPILEPSY, TONIC-CLONIC). The myoclonic episodes tend to occur shortly after awakening. Seizures tend to be aggravated by sleep deprivation and alcohol consumption. Hereditary and sporadic forms have been identified. (From Adams et al., Principles of Neurology, 6th ed, p323)
A disorder characterized by recurrent episodes of paroxysmal brain dysfunction due to a sudden, disorderly, and excessive neuronal discharge. Epilepsy classification systems are generally based upon: (1) clinical features of the seizure episodes (e.g., motor seizure), (2) etiology (e.g., post-traumatic), (3) anatomic site of seizure origin (e.g., frontal lobe seizure), (4) tendency to spread to other structures in the brain, and (5) temporal patterns (e.g., nocturnal epilepsy). (From Adams et al., Principles of Neurology, 6th ed, p313)
An anticonvulsant effective in tonic-clonic epilepsy (EPILEPSY, TONIC-CLONIC). It may cause blood dyscrasias.
An autosomal dominant inherited partial epilepsy syndrome with onset between age 3 and 13 years. Seizures are characterized by PARESTHESIA and tonic or clonic activity of the lower face associated with drooling and dysarthria. In most cases, affected children are neurologically and developmentally normal. (From Epilepsia 1998 39;Suppl 4:S32-S41)
A subtype of epilepsy characterized by seizures that are consistently provoked by a certain specific stimulus. Auditory, visual, and somatosensory stimuli as well as the acts of writing, reading, eating, and decision making are examples of events or activities that may induce seizure activity in affected individuals. (From Neurol Clin 1994 Feb;12(1):57-8)
Within medicine, nutrition (the study of food and the effect of its components on the body) has many different roles. Appropriate nutrition can help prevent certain diseases, or treat others. In critically ill patients, artificial feeding by tubes need t...
