About this study

Six subjects aged 5-11 (Cohort 1) were initially enrolled at the 8 mg/kg/day dose level. Upon completion of the study for these subjects, pharmacokinetic and safety data were analyzed to determine the target dose for the remaining subjects (either 8, 10 or 12 mg/kg/day). Depending on the selected target dose, four additional age-based cohorts of subjects were to be enrolled. LCM was increased 2 mg/kg/day per week until the target dose or maximum dose able to be tolerated was achieved.

Treatment and study plan

Drug

Other names: Vimpat

Primary outcomes

  1. Number of Subjects That Report at Least One Treatment-emergent Adverse Event During the Study (Approximately 13 Weeks)

    Time frame: 13 weeks

Secondary outcomes

  1. Change in Seizure Frequency From Baseline to End of Treatment

    Time frame: From Baseline to End of Treatment (approximately 13 weeks)

  2. Caregiver Global Impression of Change Score at Visit 5 (Day 27/28) or Early Termination

    Time frame: Visit 5 (Day 27/28) or Early Termination

    For the assessment of the Caregiver Global Impression of Change, the caregiver (including parent/legal guardian) provided his/her assessment of the subject's clinical status, compared to Baseline (Visit 1), including an evaluation of seizure frequency and intensity, the occurrence of Adverse Events (AEs), and subject's functional status.

    The caregiver will be asked to check the number that best describes the subject's condition over the past 4 weeks compared to Baseline:

    • Very much improved
    • Much improved
    • Minimally improved
    • No change
    • Minimally worse
    • Much worse
    • Very much worse

  3. Clinical Global Impression of Change Score at Visit 5 (Day 27/28) or Early Termination

    Time frame: Visit 5 (Day 27/28) or Early Termination

    For assessment of the Clinical Global Impression of Change, the investigator provided his/her assessment of the subject's clinical status, compared to Baseline (Visit 1), including an evaluation of seizure frequency and intensity, the occurrence of AEs, and subject's functional status.

    The investigator will be asked to check the number that best describes the subject's condition over the past 4 weeks compared to Baseline:

    • Very much improved
    • Much improved
    • Minimally improved
    • No Change
    • Minimally worse
    • Much worse
    • Very much worse

  4. Plasma Ctrough Values for Lacosamide at Day 7

    Time frame: Day 7

    During SP0847, the time points for collection of blood samples for plasma concentration analysis varied per enrollment cohort. To provide a standard summary of this information, we present the mean plasma trough concentrations (Ctrough). Ctrough levels represent the lowest level of LCM that was present in the subject with measurement taken pre-dose before the next scheduled dose of LCM.

    The blood sample for plasma concentration schedule varied per enrollment cohort and with protocol amendments. A PK sample was not required for a subject to be in the included in the SS although all subjects did have at least one PK sample taken during SP0847. Therefore the number of subjects presented for the PK assessments is based on the subjects in the SS who attended the respective visits and had PK concentration data at the respective time point.

  5. Plasma Ctrough Values for Lacosamide at Day 28

    Time frame: Day 28

    During SP0847, the time points for collection of blood samples for plasma concentration analysis varied per enrollment cohort.
