Brief Summary:
This study is to evaluate the long-term safety and tolerability of Lacosamide (LCM) 200 mg/day to LCM 600 mg/day taken in monotherapy in Japanese subjects who currently have partial-onset seizures with or without secondary generalization and who are treated with a single Anti-Epileptic Drug (AED) with marketing approval in Japan.

Drug Information available for: Lacosamide

Arm Intervention/treatment
Experimental: Lacosamide
Open-label, single-arm
Drug: Lacosamide

Lacosamide (LCM) immediate-release, film-coated tablets at a strength of 50 mg orally administered twice daily in two equally divided doses.

  • 4-week Titration Period: Starting on LCM 100 mg/day increased by 100 mg/day each week until 400 mg/day dose reached at the beginning of Week 4 .
  • The AED Withdrawal Period and Monotherapy Period (52- week Evaluation Period plus a Follow Up Period): During the AED Withdrawal and Monotherapy Period, the investigator may increase or decrease the dose of LCM to optimize tolerability and seizure control. The LCM dose may be decreased no lower than 200 mg/day or increased, no faster than 100 mg/day per week, up to 600 mg/day.

Primary Outcome Measures :
  1. Number of Subjects With at Least One Incidence of Treatment-Emergent Adverse Events (TEAEs) During the Study [ Time Frame: From the Titration Period (investigational product is taken) to the End of Study Visit (up to 3.5 years) ]
    An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation subject 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.

  2. Number of Subjects Who Withdraw Due to Adverse Events (AEs) During the Study [ Time Frame: From the Titration Period (investigational product is taken) to the End of Study Visit (up to 3.5 years) ]
    An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation subject 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.

  3. Number of Subjects With at Least One Incidence of Serious Adverse Events (SAEs) During the Study [ Time Frame: From the Titration Period (investigational product is taken) to the End of Study Visit (up to 3.5 years) ]

    A Serious Adverse Event (SAE) is any untoward medical occurrence that at any dose:

    • Results in death
    • Is life-threatening
    • Requires in patient hospitalization or prolongation of existing hospitalization
    • Is a congenital anomaly or birth defect
    • Is as infection that requires treatment parenteral antibiotics
    • Other important medical events which based on medical or scientific judgement may jeopardize the patients, or may require medical or surgical intervention to prevent any of the above


Secondary Outcome Measures :
  1. Number of Subjects Remaining Seizure Free for 6 Consecutive Months During the Monotherapy Period [ Time Frame: From the beginning of the Monotherapy Period to the end of the Follow-Up Period (up to 3.1 years until the time of approval granted) ]

    Subjects were considered seizure free if their seizure counts for every day over the entire Treatment Period was zero and if they completed the Treatment Period.

    A subject was considered seizure free, if no seizure occurred during the 6 consecutive months in the Evaluation Period. If one of the following occurred, the subject was not considered seizure free:

    • A documented seizure during 6 consecutive months of the Evaluation Analysis Period
    • Subject discontinued the study prematurely during the Evaluation Analysis Period
    • Missing Seizure Count Case Report Forms (CRFs) prior to completing the Evaluation Analysis Period

  2. Number of Subjects Remaining Seizure Free for 12 Consecutive Months During the Monotherapy Period [ Time Frame: From the beginning of the Monotherapy Period to the end of the Follow-Up Period (up to 3.1 years until the time of approval granted) ]

    Subjects were considered seizure free if their seizure counts for every day over the entire Treatment Period was zero and if they completed the Treatment Period.

    A subject was considered seizure free, if no seizure occurred during the 12 consecutive months in the Evaluation Period. If one of the following occurred, the subject was not considered seizure free:

    • A documented seizure during 6 consecutive months of the Evaluation Analysis Period
    • Subject discontinued the study prematurely during the Evaluation Analysis Period
    • Missing Seizure Count Case Report Forms (CRFs) prior to completing the Evaluation Analysis Period.

    Subjects who discontinued before the end date of 6 consecutive months were included in this analysis.


  3. Percentage of Participants in the Monotherapy Period Without Discontinuation Due to Adverse Events (AE) or Lack of Efficacy (LOE) [ Time Frame: From the beginning of the Monotherapy Period to the end of the Follow-Up Period (up to 3.1 years until the time of approval granted) ]
    For Time to discontinuation (event), Retention rate and 95% CI was calculated using the Kaplan-Meier method. Retention rate is indicated in Percent and 95% confidence intervals (CI) with respect to the Time to discontinuation.

  4. Plasma Concentrations of Lacosamide Versus Time Postdose [ Time Frame: From Titration Period up to Week 94 ]
    Dose-normalized lacosamide Plasma Concentration (µg/mL) by Visit and Dose during the Evaluation Period.

  • Subject has sick sinus syndrome without a pacemaker, or a second or third degree atrioventricular (AV) block, or subject has any other clinically relevant electrocardiogram (ECG) abnormalities
