    Number of Participants with Death, Serious Adverse Events, Treatment emergent adverse events (TEAEs) leading to subject discontinuation from study

Secondary Outcome Measures :
  1. Treatment Success [ Time Frame: Duration of individual subject participation was open-ended. Study ended early. Longest subject participation approximately 6 months. ]
    Termination of seizure(s) within 10 minutes and no recurrence within 6 hours after study drug administration. Due to early termination of the study, this data was not analyzed.
