1.Primary Outcome
Title Number of Subjects With at Least One Incidence of Treatment-Emergent Adverse Events (TEAEs) During the Study
Hide Description An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.

Hide Description

A Serious Adverse Event (SAE) is any untoward medical occurrence that at any dose:

  • Results in death
  • Is life-threatening
  • Requires in patient hospitalization or prolongation of existing hospitalization
  • Is a congenital anomaly or birth defect
  • Is as infection that requires treatment parenteral antibiotics
  • Other important medical events which based on medical or scientific judgement may jeopardize the patients, or may require medical or surgical intervention to prevent any of the above

4.Secondary Outcome
Title Number of Subjects Remaining Seizure Free for 6 Consecutive Months During the Monotherapy Period
Hide Description

Subjects were considered seizure free if their seizure counts for every day over the entire Treatment Period was zero and if they completed the Treatment Period.

  • A documented seizure during 6 consecutive months of the Evaluation Analysis Period
  • Subject discontinued the study prematurely during the Evaluation Analysis Period
  • Missing Seizure Count Case Report Forms (CRFs) prior to completing the Evaluation Analysis Period
Time Frame From the beginning of the Monotherapy Period to the end of the Follow-Up Period (up to 3.1 years until the time of approval granted)
