ListOutcomeTime frameDescription
PrimaryChange in Partial Onset Seizure (POS) Frequency Per 28 Days From Baseline to the Maintenance PeriodBaseline to Week 16 (or last value on treatment)The POS frequency is standardized to a 28-day duration. Negative values indicate improvement from Baseline.
SecondaryProportion of Responders Where a Responder is Defined as a Participant With >= 50% Reduction in Partial Onset Seizure Frequency Per 28 Days From Baseline to the Maintenance PeriodBaseline to Week 16 (or last value on treatment)
Proportion of responders is presented as percentage of participants. A responder is a subject experiencing a 50 % or greater reduction in partial onset seizure frequency per 28 days from Baseline to the Maintenance Period.
SecondaryProportion of Subjects Experiencing a >=25 % to <50 %, 50 % to 75 %, or >75 % Reduction in Partial Onset Seizure Frequency Per 28 Days From Baseline to the End of Maintenance PeriodBaseline to Week 16 (or last value on treatment)
Proportion of subjects is presented as percentage of participants. A \>=25%-\<50% response in the Maintenance Period is defined as \>=25% to \<50% reduction in POS frequency per 28 days from Baseline to end of Maintenance Period. A \>=50%-\<=75% response in the Maintenance Period is defined as \>=50% to \<=75% reduction in POS frequency per 28 days from Baseline to end of Maintenance Period. A 75% response in the Maintenance Period is defined as \>75% reduction in POS frequency per 28 days from Baseline to end of Maintenance Period.
SecondaryChange in Partial Onset Seizure Frequency Per 28 Days From Baseline to the Entire Treatment (ie, Titration+Maintenance Periods)Baseline to Week 16 (or last value on treatment)The POS frequency is standardized to a 28-day duration. Negative values indicate improvement from Baseline.
Secondary
Proportion of Subjects Experiencing a >=25 % to <50 %, 50 % to 75 %, or >75 % Reduction in Partial Onset Seizure Frequency Per 28 Days From Baseline to the Entire Treatment (ie, Titration+Maintenance Periods)
Baseline to Week 16 (or last value on treatment)
Proportion of subjects is presented as percentage of participants. A \>=25%-\<50% response in the Treatment Period is defined as \>=25% to \<50% reduction in POS frequency per 28 days from Baseline to end of Treatment Period. A \>=50%-\<=75% response in the Treatment Period is defined as \>=50% to \<=75% reduction in POS frequency per 28 days from Baseline to end of Treatment Period. A 75% response in the Treatment Period is defined as \>75% reduction in POS frequency per 28 days from Baseline to end of Treatment Period.
Secondary
Proportion of Subjects Experiencing no Change in Partial Onset Seizure Frequency (Between <25 % Reduction and <25 % Increase) Per 28 Days From Baseline to the Entire Treatment (ie, Titration+Maintenance Periods)
Baseline to Week 16 (or last value on treatment)
Proportion of subjects is presented as percentage of participants. No change is defined as between \<25% reduction and \<25% increase in POS frequency per 28 days from Baseline to the entire Treatment Period, otherwise not between \<25% reduction and \<25% increase is defined as a change.
SecondaryProportion of Subjects Experiencing an Increase in Partial Onset Seizure Frequency Per 28 Days of >=25 % From Baseline to the Entire Treatment (ie, Titration+Maintenance Periods)Baseline to Week 16 (or last value on treatment)
Proportion of subjects is presented as percentage of participants. An increase is defined as a \>=25% increase in POS frequency per 28 days from Baseline to the entire Treatment Period, otherwise \<25% increase is defined as no increase.
SecondaryChange in Partial Onset Seizure Frequency Per 28 Days From Baseline to the Entire Treatment (ie, Titration+Maintenance Periods) for Simple Partial SeizuresBaseline to Week 16 (or last value on treatment)The POS frequency is standardized to a 28-day duration. Negative values indicate improvement from Baseline.
SecondaryChange in Partial Onset Seizure Frequency Per 28 Days From Baseline to the Entire Treatment (ie, Titration+Maintenance Periods) for Complex Partial SeizuresBaseline to Week 16 (or last value on treatment)The POS frequency is standardized to a 28-day duration. Negative values indicate improvement from Baseline.
SecondaryChange in Partial Onset Seizure Frequency Per 28 Days From Baseline to the Entire Treatment (ie, Titration+Maintenance Periods) for Secondary Generalized SeizuresBaseline to Week 16 (or last value on treatment)The POS frequency is standardized to a 28-day duration. Negative values indicate improvement from Baseline.
