E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective of this study is to evaluate the efficacy of adjunctive JNJ 40411813 compared to placebo in participants with focal onset seizures who are receiving levetiracetam or brivaracetam and up to 3 other anti-epileptic drugs (AEDs) |
|
E.2.2 | Secondary objectives of the trial |
-To evaluate the overall safety and tolerability of adjunctive JNJ-40411813 compared to placebo in participants with focal onset seizures who are receiving levetiracetam or brivaracetam and up to 3 other AEDs. -To evaluate the efficacy of adjunctive JNJ-40411813 compared to placebo in participants with focal onset seizures. -To evaluate the efficacy of JNJ-40411813 over the double-blind period -To evaluate the pharmacokinetics (PK) of JNJ-40411813 |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Participants must be men or women, 18 to 69 years of age, inclusive. 2. Body Mass Index (BMI) between 18 and 35 kg/m2 inclusive (BMI=weight/height2). Minimum body weight should be 40 kg. 3. Established diagnosis of focal epilepsy, for at least 1 year using the International League Against Epilepsy (ILAE) criteria (Fisher 2017). 4. Must have had a neuroimaging procedure within 10 years, including a computed tomography (CT) scan or magnetic resonance imaging (MRI), that excluded a progressive neurologic disorder. 5. Cohort 1: Current treatment with at least 1 and up to 4 AEDs (including levetiracetam), administered at the appropriate dosage(s) and for a sufficient treatment period before screening, these AEDs must remain unchanged throughout the pretreatment. Cohort 2 and beyond: Current treatment with at least 1 and up to 4 AEDs (including levetiracetam or brivaracetam), administered at the appropriate dosage(s) and for a sufficient treatment period before screening. These AEDs must remain unchanged throughout the pretreatment and double-blind treatment periods (with the exception of dosage reductions of concomitant AEDs because of suspected elevated AED levels or side effects). Important note: screening of patients receiving Brivaracetam will start when enrolling for Cohort 2.

E.4 | Principal exclusion criteria |

History of any current or past nonepileptic seizures, including psychogenic seizures. 5. Recently initiated vagus nerve stimulation, deep brain and cortical stimulation.
