Outcome Measures

Primary Outcomes (1)

  • Primary efficacy endpoints are percent reduction in partial onset seizure frequency in the US and the rest of the world (excluding Europe, Australia, New Zealand, S Africa), and responder rate for Europe, Australia, New Zealand, S Africa

    from baseline relative to the entire double-blind treatment phase (14 weeks)

Secondary Outcomes (1)

  • Secondary endpoints are percent reduction in partial onset seizure frequency for EuropeAustraliaNew Zealand S Africa, percent reduction in secondarily generalized seizure and time to onset of treatment effect on partial onset seizure frequency reduction

    from baseline relative to the entire double-blind treatment phase (14 weeks)

Eligibility Criteria

Age16 Years+
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17), Adult (18-64), Older Adult (65+)

You may qualify if:

  • Diagnosis of partial onset seizures
  • had a neuroimaging procedure (computed tomography \[CT\] or magnetic resonance imaging \[MRI\] within the past 5 years that excluded a progressive neurologic disorder
  • History of inadequate response to at least 1 antiepileptic drug
  • Current treatment with at least 1 and up to 3 antiepileptic drugs. To be eligible for the double-blind treatment phase of study CARISEPY3013, patients must: have at least 6 partial onset seizures during the 56-day baseline period
  • Have not had \> = 100 partial onset seizures per 28 days in the baseline period
  • And no seizure-free period of more than 3 weeks during the baseline period.

You may not qualify if:

  • History of status epilepticus or epilepsia partialis continua in the 6 months before study entry
  • Have a generalized epileptic syndrome
  • have a diagnosis of Lennox-Gastaut Syndrome
  • Currently experiencing seizures that cannot be counted accurately
  • have experienced rates of \> = 100 partial onset seizures in any monthly period in the 6 months before study entry
  • Have a history of any current or past nonepileptic seizures, including psychogenic seizures
  • History of or current serious or medically unstable systemic disease
  • evidence of cardiac disease, including unstable angina, myocardial infarction, within the past 2 years, uncontrolled heart failure, major arrhythmias, congenital short QT syndrome, or significant shortening or lengthening of the QTc interval of the electrocardiogram
  • progressive neurologic disorder, such as a brain tumor, demyelinating disease, and degenerative CNS disease, or active CNS infection
  • current or past (within the past year) major psychotic disorder
  • History of suicidal or homicidal ideation within the past 2 years, or an episode of suicide attempt or homicide at any time in the past.
