Arm Description

At the end of the baseline phase, patients meeting the final selection criteria were admitted to three consecutive 4-week treatment periods in which they received Eslicarbazepine acetate once-daily at the following dosage regimens: 5 mg/kg/day in the first 4 weeks, 15 mg/kg/day in weeks 5-8 and 30 mg/kg/day or 1800 mg/day, whichever less, in weeks 9-12. After the last treatment period, dose was down-titrated during a 2-week period or patient continued receiving Eslicarbazepine acetate ("compassionate use") if both parent(s)/guardian(s)/patient and his/her physician agreed this was in the best patient's interest. For Group 1 (2-6 years), oral suspension 50 mg/mL was used. The dose was to be rounded to the nearest 25 mg unit.

For Group 2 (7-11 years) and Group 3 (12-17 years), Eslicarbazepine acetate strengths 200 mg, 400 mg, 600 mg and 800 mg tablets might be used. The dose was to be rounded to the nearest 100 mg unit. Half tablets might be used for dosage adjustment (tablets were scored).

Outcomes

Primary Outcome Measures

Maximum Observed Plasma Drug Concentration (Cmax) Post-dose
Time of Occurrence of Cmax (Tmax).

Secondary Outcome Measures

Percentage Change in Seizure Frequency During Each 4-week Treatment Period Compared to the Baseline Phase
The efficacy variables were the percentage change in seizure frequency during each 4-week treatment period compared to the baseline phase. Seizures were recorded in the patient's diary during the baseline phase and during the following 4-week treatment periods. Seizure frequency for each patient was standardised to a frequency per 28 days period (i.e., mean daily frequency multiplied by 28). Changes in seizure frequency were analysed for each age group separately.

5. Study Description

Brief Summary
The purpose of this study is to characterize the pharmacokinetics of Eslicarbazepine acetate in children and adolescents with epilepsy.
Detailed Description
This clinical study was planned to be performed as an open-label, single-centre, multiple-dose study, in 30 paediatric epileptic patients distributed by 3 age groups of 10 patients each: 2-6 years [Group 1], 7-11 years [Group 2], and 12-17 years [Group 3]. The study was constituted by a 4-week baseline phase, followed by 3 consecutive 4-week treatment periods with Eslicarbazepine acetate in which patients received Eslicarbazepine acetate once-daily at the following dosage regimens: 5 mg/kg/day (weeks 1-4), 15 mg/kg/day (weeks 5-8) and 30 mg/kg/day or 1800 mg/day, whichever less (weeks 9-12). At the end of each 4-week treatment period, patients were hospitalised and serial blood samples for drug assays were obtained over a dosing interval. After the last treatment period or in the event of premature discontinuation, the dose had to be down-titrated during a 2-week period. After the last treatment period patient could continue receiving Eslicarbazepine acetate ("compassionate use") if both parent(s)/guardian(s) /patient and his/her physician agreed this was in the best patient's interest. A follow-up visit occurred approximately 4 weeks after the last hospitalisation or early discontinuation.
