A Study of Levetiracetam in Japanese Pediatric Patients With Generalized Tonic-clonic Seizures

27. april 2015 opdateret af: UCB Japan Co. Ltd.

An Open-label, Single-arm, Multicenter Study to Evaluate the Efficacy and Safety of Adjunctive Treatment With Levetiracetam in Japanese Patients (≥4 to <16 Years) With Uncontrolled Generalized Tonic-clonic (GTC) Seizures Despite Treatment With 1 or 2 Antiepileptic Drug(s)

To evaluate the efficacy and safety of Levetiracetam dry syrup at doses up to 60 mg/kg/day or 3000 mg/day used as adjunctive therapy in Japanese pediatric patients aged ≥4 to <16 years with uncontrolled Generalized Tonic-Clonic (GTC) seizures despite treatment with 1 or 2 Anti-Epileptic Drugs (AEDs).

Beskrivelse

Inclusion Criteria:

  • An epileptic patient with generalized tonic-clonic seizures that are classifiable according to the International League Against Epilepsy classification of epileptic seizures (Epilepsia, 1981)
  • A patient on a stable dose of 1 or 2 anti-epileptic drugs for the last 4 weeks (potassium bromide and sodium bromide for the last 12 weeks) prior to the Combined Baseline Period and during the Combined Baseline Period

Exclusion Criteria:

  • Presence of any sign (clinical or imaging procedures) suggesting a progressive brain lesion/disease, in particular, progressive disorder with epileptic seizures
  • Diagnosis of Lennox-Gastaut Syndrome
  • Confirmed focal epilepsy based on clinical signs (seizure types), with consistent electroencephalogram and magnetic resonance imaging features
  • A history of convulsive or nonconvulsive status epilepticus while taking concomitant anti-epileptic drugs for the last 3 months prior to Visit 1

Foranstaltningsbeskrivelse
Tidsramme
The Percent Change From the Combined Baseline (4-week Retrospective Baseline and 4-week Prospective Baseline) in the Generalized Tonic-clonic Seizure Frequency Per Week Over the 24-week Treatment Period (Up-Titration and Evaluation Periods)
Tidsramme: From Baseline (Week -8) to Treatment Period (Week 0 to Week 24)

The percent change from Combined Baseline over Treatment Period was calculated from the Generalized Tonic-Clonic (GTC) seizure frequency per week during the Treatment Period (T) and during the Baseline Period (B, Combined Baseline, ie, Retrospective and Prospective Baseline Periods) using the equation below.

The percent change from Baseline = (B - T)/B x 100

The seizure frequency per week was calculated using the following formula:

Frequency per week of GTC seizures = total number of GTC seizures in the corresponding period / number of days for observation in the corresponding period x 7
From Baseline (Week -8) to Treatment Period (Week 0 to Week 24)

The Percent Change in Generalized Tonic-clonic Seizure Frequency Per Week From the Combined Baseline Period Over the Evaluation Period
Tidsramme: From Baseline (Week -8) to Evaluation Period (Week 4 to Week 24)

The percent change from Combined Baseline over Evaluation Period was calculated from the Generalized Tonic-Clonic (GTC) seizure frequency per week during the Evaluation Period (E) and during the Baseline Period (B, Combined Baseline, ie, Retrospective and Prospective Baseline Periods) using the equation below.

The percent change from Baseline = (B - E)/B x 100

The seizure frequency per week was calculated using the following formula:

Frequency per week of GTC seizures = total number of GTC seizures in the corresponding period / number of days for observation in the corresponding period x 7

The 50 % responder rate during the Treatment Period was the proportion of subjects who reported a ≥ 50 % reduction in seizure frequency per week from Baseline during the Treatment Period.

Generalized Tonic-clonic Seizures 50 % Responder Rate During the Evaluation Period

Generalized Tonic-clonic Seizure Freedom Over the Treatment Period
Tidsramme: Treatment Period (Week 0 to Week 24)
A subject with a generalized tonic-clonic seizure frequency of 0 per week throughout the Treatment Period was considered a seizure-free subject for that period.
