Not Treated
Participant (de novo) signed the informed consent form (ICF) but never received any study medication during the study.
Any ZX008 Open Label Dose
Participants received ZX008 0.2 milligram per kilogram per day (mg/kg/day) as an oral solution, twice a day (bid), in equally divided doses with food for 1 month. After 1 month, investigator might have adjusted the dose of each participant based on effectiveness and tolerability. Participants who were not receiving concomitant stiripentol, dose changes should be made in increments of 0.2 mg/kg/day, to a maximum of 0.8 mg/kg/day but not to exceed total dose of 30 mg/day for 42 months of OLE Period. Participants who were receiving concomitant stiripentol, the first dose change was 0.4 mg/kg/day and the final dose change was to 0.5 mg/kg/day, but not to exceed 20 mg/day for 42 months of OLE Period.

SECONDARY outcome

Timeframe: From Day 1 to End of OLE Treatment Period (EOS Visit - up to Month 42), compared to Baseline (Core)

Population: Modified Intent-to-Treat (mITT) population included all enrolled participants who received at least one dose of ZX008 and had at least 1 month of valid seizure data during the OLE.

Baseline (Core) was defined as Baseline prior to double-blind treatment in the core studies (ZX008-1501/ZX008-1502, and ZX008-1504 Cohort 2). Participants in 1504- Cohort 1 and de novo participants (who entered 1503 without having been in any of the core studies) did not have a Baseline (Core), and were not included in the analysis of this outcome measure. The total number of convulsive seizures from Day 1 to EOS was divided by the total number of days from Day 1 to EOS with nonmissing diary data and the result was then multiplied by 28 to get a 28-day convulsive seizure frequency (CSF). The change from Baseline for any individual participant was calculated by subtracting the Baseline (Core) from the post-baseline value. Monthly (28 day) CSF was based on electronic diary data obtained for each participant.

Monthly (28 day) CSF was based on electronic diary data obtained for each participant. The total number of convulsive seizures in the ith interval (CSF in OLE, where, i=1, 2, 3, … , 14 ) was divided by the total number of days in the ith interval with nonmissing diary data and the result was then multiplied by 28 to get a 28-day CSF of OLE.

SECONDARY outcome

Timeframe: From Day 1 to End of OLE Treatment Period - End of Study (EOS) Visit (Month 42)

Population: mITT population included all enrolled participants who received at least one dose of ZX008 and had at least 1 month of valid seizure data during the OLE. Here, number analyzed represents the number of participants categorized by mean daily dose.

Convulsive seizure frequency over time, reported as per 28 days was analyzed by the actual dose administered. Participants were grouped into low (0.2 to \<0.4 mg/kg), medium (0.4 to \<0.6 mg/kg), and high dose (\>0.6 mg/kg) groups depending on their mean daily doses of ZX008 during the OLE Treatment period. For each participant, the seizure frequency per 28 days was calculated as the number of seizures recorded during the period, divided by the number of days in the period and multiplied by 28. The convulsive seizure frequency was calculated from all available data collected.

Population: mITT population included all enrolled participants who received at least one dose of ZX008 and had at least 1 month of valid seizure data during the OLE.

Participants in the study were required to be on stable background therapy for the first 6 months of treatment, after which background AEDs could be reduced or withdrawn so long as one background AED remained. The percentage of participants who had changes in dose or type of concomitant AED medications during the first, second, third, fourth, fifth, and sixth months were analyzed and reported.
