Experimental: Lacosamide
Lacosamide treatment of 100 - 400 mg/day for long-term
|
Drug: Lacosamide
Strength: Lacosamide (LCM) 50 mg, LCM 100 mg Formulation: Tablet Frequency: twice daily during the study period (until the date of approval) At the completion of EP0008 [NCT01710657], all subjects who choose to enroll in EP0009 will be taking a dose of Lacosamide 200 mg/day. At the beginning of EP0009, the investigator may maintain the LCM dose or increase or decrease the dose. During the Treatment Period, the investigator will be allowed to increase or decrease the dose of LCM to optimize tolerability and seizure reduction. The LCM dose may be decreased to 100 mg/day or increased, no faster than 100 mg/day per week, up to 400 mg/day. Other Name: Vimpat |
- Number of Participants With at Least One Adverse Event Reported Spontaneously by the Subject or Observed by the Investigator From Baseline Until the End of Study Visit [ Time Frame: From Visit 1 (Week 0) up to approximately Week 323 ]An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
- Number of Participants That Withdrew Due to Adverse Events From Baseline Until the End of Study Visit [ Time Frame: From Visit 1 (Week 0) up to approximately Week 323 ]An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation participant administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment and led to the withdrawal of the participants from the study. An AE could therefore be any unfavorable and unintended sign, symptom, or disease temporally associated with the use of a medicinal (investigational) product, whether or not related to the medicinal (investigational) product.
- Percent Change in Partial-onset Seizure Frequency Per 28 Days From Baseline of Study EP0008 [NCT01710657] Until the End of Study Visit in Study EP0009 [ Time Frame: From Visit 1 in study EP0008 [NCT01710657] up to approximately Week 323 in study EP0009 ]The percent change from Baseline to the Treatment Period was calculated as {[(Seizure frequency per 28 days during the Treatment Period) minus (Seizure frequency per 28 days during Baseline Period)] divided by (Seizure frequency per 28 days during Baseline Period)} multiplied by 100. Baseline was defined as the Baseline Period of study EP0008 [NCT01710657].
- Percentage of Participants With 50 % Response Rate in Partial-onset Seizure Frequency Per 28 Days From Baseline of Study EP0008 [NCT01710657] Until the End of Study Visit in Study EP0009 [ Time Frame: From Visit 1 in study EP0008 [NCT01710657] up to approximately Week 323 in study EP0009 ]A responder is a subject experiencing a greater than or equal to (≥) 50 % reduction in partial-onset seizure frequency per 28 days from baseline. Baseline was defined as the Baseline Period of study EP0008 [NCT01710657].
