Study Evaluating the Pharmacokinetics of Keppra Extended Release (XR) in Children and Adults With Epilepsy

July 10, 2015 updated by: UCB BIOSCIENCES, Inc.

An Open-Label, Multicenter, Parallel-Group, Two-Arm Study Comparing the Pharmacokinetics of Keppra XR in Children (Aged 12 - 16 Years Old) With Epilepsy and in Adults (Aged 18 - 55 Years Old) With Epilepsy

To study how the body absorbs, distributes, metabolises and eliminates Keppra XR in both children (12 to 16 years old) and adults (18 to 55 years old) with epilepsy.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Maximum Concentration at Steady State (Cmax) of Keppra XR Normalized by Dose and by Body Weight and Dose During up to 7 Days of Administration
Time Frame: 6 pharmacokinetic samples were taken pre-dose, 1, 2.5, 4, 6 and 10 hours after administration, at Day 4, 5, 6, or 7 of Keppra XR administration.

The Cmax is the maximum plasma concentration normalized by dose and by body weight and dose.

Cmax normalized by 1000 mg dose was calculated as:

Cmax/(mg dose taken/ 1000 mg Keppra XR).

Cmax normalized by body weight and dose (1 mg Keppra XR/kg) was calculated as:

Cmax/(bodyweight (kg)/ mg dose Keppra XR taken).

Pharmacokonetic (PK) samples were taken predose and 1h, 2.5h, 4h, 6h and 10h after study medication at day 4, 5, 6 or 7 of Keppra XR administration.
6 pharmacokinetic samples were taken pre-dose, 1, 2.5, 4, 6 and 10 hours after administration, at Day 4, 5, 6, or 7 of Keppra XR administration.
Area Under the Plasma Concentration Curve Over a Dosing Interval of 24 Hours (AUCtau) of Keppra XR Normalized by Dose, and by Body Weight and Dose During up to 7 Days of Administration
Time Frame: 6 pharmacokinetic samples were taken pre-dose, 1, 2.5, 4, 6 and 10 hours after administration, at Day 4, 5, 6, or 7 of Keppra XR administration.

AUCtau normalized by 1000 mg dose was calculated as:

AUCtau/(mg dose taken/ 1000 mg Keppra XR).

AUCtau normalized by body weight and dose (1 mg Keppra XR/kg) was calculated as:

AUCtau/(bodyweight (kg)/ mg dose Keppra XR taken).

6 PK samples were taken pre-dose, 1, 2.5, 4, 6 and 10 hours after administration, at Day 4, 5, 6, or 7 of Keppra XR administration. At steady state, reached after 2 days of administration of Keppra XR, the concentrations at 24h postdose is equal to the predose concentration. The predose concentration was used as the 24h concentration to calculate AUCτau.
6 pharmacokinetic samples were taken pre-dose, 1, 2.5, 4, 6 and 10 hours after administration, at Day 4, 5, 6, or 7 of Keppra XR administration.
Time of Maximum Plasma Concentration (Tmax) of Keppra XR During up to 7 Days of Administration
Time Frame: 6 pharmacokinetic samples were taken pre-dose, 1, 2.5, 4, 6 and 10 hours after administration, at Day 4, 5, 6, or 7 of Keppra XR administration.
The Tmax is the time corresponding to the maximum plasma concentration of Keppra XR. It was directly obtained from the observed concentration versus time curve. 6 pharmacokinetic samples were taken pre-dose, 1, 2.5, 4, 6 and 10 hours after administration, at Day 4, 5, 6, or 7 of Keppra XR administration.
6 pharmacokinetic samples were taken pre-dose, 1, 2.5, 4, 6 and 10 hours after administration, at Day 4, 5, 6, or 7 of Keppra XR administration.
Apparent Total Body Clearance (CL/F) of Keppra XR During up to 7 Days of Administration
Time Frame: 6 pharmacokinetic samples were taken pre-dose, 1, 2.5, 4, 6 and 10 hours after administration, at Day 4, 5, 6, or 7 of Keppra XR administration.
The Apparent Total Body Clearance (CL/F) was calculated as Dose/ AUCtau. 6 pharmacokinetic samples were taken pre-dose, 1, 2.5, 4, 6 and 10 hours after administration, at Day 4, 5, 6, or 7 of Keppra XR administration.
6 pharmacokinetic samples were taken pre-dose, 1, 2.5, 4, 6 and 10 hours after administration, at Day 4, 5, 6, or 7 of Keppra XR administration.

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Occurrence of Treatment-Emergent Adverse Events From Starting Study Drug Treatment (Day 1) to up to 14 Days
Time Frame: From Starting Study Drug Treatment (Day 1) to up to 14 days
An Adverse Event (AE) is any untoward medical occurrence in a subject or clinical investigation subject administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment. Treatment emergent means that an AE has begun or got worse after start of Keppra XR administration.
From Starting Study Drug Treatment (Day 1) to up to 14 days
