What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Partial Onset Seizure (Type I) Frequency Per Week Over the 12-week Treatment Period
Time Frame: Baseline to 12-week Treatment Period

Partial (Type I) seizures can be classified into one of the following three groups:

  • Simple partial seizures
  • Complex partial seizures
  • Partial seizures evolving to generalized tonic-clonic convulsions.

Partial Onset Seizure (POS) Frequency per week over the Treatment Period (TP) was calculated as:

(Total Type I seizures over the TP)*7/(Total number of days with no missing seizure count in the TP)

Baseline to 12-week Treatment Period

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Responder Rate for Partial Onset Seizure (Type I) Frequency Per Week Over the 12-week Treatment Period
Time Frame: Baseline to 12-week Treatment Period
The responder rate was presented as the number of responders and non-responders. A subject is a responder, if the subject has at least 50 % reduction in partial onset seizure frequency per week from Baseline to Treatment Period. Subjects with zero seizure frequency per week at Baseline were considered as non-responders.
Baseline to 12-week Treatment Period
All Seizure Frequency (Type I+II+III) Per Week Over the 12-week Treatment Period
Time Frame: Baseline to 12-week Treatment Period

There are three different types of seizures:

  • Type I: Partial seizures
  • Type II: Generalized seizures
  • Type III: Unclassified epileptic seizures.

All seizure frequency per week over Treatment Period (TP) was calculated as: (Total number of seizures over the TP)*7/(Total number of days with no missing seizure count in the TP)

Baseline to 12-week Treatment Period
Percent Change From Baseline to the 12-week Treatment Period in Partial Onset Seizure (Type I) Frequency Per Week
Time Frame: Baseline to 12-week Treatment Period

Percent change from Baseline was calculated as percent reduction by:

(weekly seizure frequency Baseline - weekly seizure frequency Treatment)*100/(weekly seizure frequency Baseline).

The higher the values for percent change in Partial Onset Seizure (POS) frequency, the higher the improvement from Baseline.

Baseline to 12-week Treatment Period
Categorized Percentage Change From Baseline in Seizure Frequency for Partial Onset Seizure (Type I) Over the 12-week Treatment Period
Time Frame: Baseline to 12-week Treatment Period

Subjects were classified in 1 of the following categories based on their percent reduction from Baseline to Treatment Period in Partial Onset Seizure (POS) frequency per week: <-25 %, -25 % to <25 %, 25 % to <50 %, 50 % to <75 %, 75 % to <100 %, and 100 %.

Subjects having zero for Baseline seizure frequency per week were classified in the <-25 % category.

Baseline to 12-week Treatment Period
Seizure Freedom Rate (All Seizure Types) Over the 12-week Treatment Period
Time Frame: Baseline to 12-week Treatment Period

Subjects were considered seizure free if their seizure counts for every day over the Treatment Period (TP) was zero and if they did not discontinue before the end of the TP. Seizure freedom rate was calculated as:

(total number of seizure - free subjects in treatment group during TP)/(total number of evaluable Intent-To-Treat (ITT) subjects in treatment group)

Baseline to 12-week Treatment Period
Time to First Type I Seizure During the 12-week Treatment Period
Time Frame: Baseline to 12-week Treatment Period
The time to first Partial Onset Seizure (POS) in the Treatment Period is defined as the time between beginning of the Treatment Period and the date of occurrence of first Type I seizure. Subjects withdrawing during the Treatment Period before having a first Type I seizure were considered as having a first Type I seizure on the last day of their Treatment Period.
Baseline to 12-week Treatment Period
Time to Fifth Type I Seizure During the 12-week Treatment Period
Time Frame: Baseline to 12-week Treatment Period
The time to fifth Partial Onset Seizure (POS) in the Treatment Period is defined as the time between beginning of the Treatment Period and the date of occurrence of fifth Type I seizure. Subjects withdrawing during the Treatment Period before having a fifth Type I seizure were considered as having a fifth Type I seizure on the last day of their Treatment Period.
Baseline to 12-week Treatment Period
Time to Tenth Type I Seizure During the 12-week Treatment Period
Time Frame: Baseline to 12-week Treatment Period
The time to tenth Partial Onset Seizure (POS) in the Treatment Period is defined as the time between beginning of the Treatment Period and the date of occurrence of tenth Type I seizure. Subjects withdrawing during the Treatment Period before having a tenth Type I seizure were considered as having a tenth Type I seizure on the last day of their Treatment Period.
Baseline to 12-week Treatment Period
Reduction of Type IC/Type I Seizure Frequency Ratio From Baseline to the 12- Week Treatment Period
Time Frame: Baseline to 12-week Treatment Period
The type IC/Type I seizure frequency ratio is represented by the percentage of subjects having a reduction in the ratio of Type IC seizure frequency over Type IA, IB, and IC seizure frequency from Baseline to Treatment Period.
Baseline to 12-week Treatment Period
Change From Baseline to the 12-week Treatment Period in Total Patient Weighted Quality of Life in Epilepsy Inventory-Form 31 (QOLIE-31-P) Score

The subscale scores, the total score and the health status item score range from 0 to 100 and higher scores indicating better function.

Baseline to 12-week Treatment Period
Change From Baseline to the 12-week Treatment Period in Hospital Anxiety Score
Time Frame: Baseline to 12-week Treatment Period
The Hospital Anxiety and Depression Scale (HADS) was used to evaluate anxiety and depression. The HADS was developed as a self administered scale to assess the presence and severity of both anxiety and depression simultaneously. It consists of 14 items that are scored on a 4-point severity scale ranging from 0 to 3. A score per dimension was calculated with each score ranging from 0 to 21 and higher scores indicating higher depression / anxiety. A negative value in change from Baseline shows an improvement in HADS from Baseline.
