When analyzed across age cohorts, the 50% or greater responder rates in subjects aged 4 to 7 years and 7 to 12 years were 18 and 51 for total POS seizures in POS cohort and 2 and 12 for PGTC seizures in the PGTC cohort, respectively.When analyzed across with and without concomitant EIAED cohorts, the 50% or greater responder rates for total POS seizures in the POS cohort were 21(45.7%)and 48(47.1%)in subjects with or without concomitant EIAEDs, respectively.A responder rate of 50% or greater was achieved in 14(63.6%)subjects without concomitant EIAEDs in the PGTC cohort.There were 2 PGTC subjects in the inducer cohort but neither of them had PGTC seizures at baseline.Seizure-free status was achieved in 17(11.5%)subjects for total POS seizures in the POS cohort, and 12(54.5%)for PGTC seizures in the PGTC cohort.When analyzed across with and without concomitant EIAED cohorts, the seizure-free rates for total POS seizures in the POS cohort were 5(10.9%)and 12(11.8%).Seizure-free status was achieved in 12(54.5%)subjects without concomitant EIAEDs in the PGTC cohort.When analyzed across age cohorts, the 50% or greater responder rates in subjects aged 4 to
