Number of Study Participants With Treatment-emergent Adverse Events (TEAEs) Over the Duration of the Treatment Period |
AEs were considered treatment-emergent if event had onset on or after date of first study medication dose in EP0012 and within 30 days following last study medication dose or events whose intensity worsened on or after date of first study medication dose and within 30 days following date of last study medication administration. Adverse Events were reported spontaneously by the participant and/or caregiver or observed by the investigator. |

Number of Study Participants With New Appearance of Absence and/or Myoclonic Seizures During the Treatment Period |
The number of study participants with appearance of new absence and/or myoclonic seizure types experienced during the Treatment Period but who did not experience in Combined Baseline Period or in seizure classification history, before taking LCM were reported. To determine appearance of new seizure type, the Combined Baseline Period was used. Thus, the participants who directly enrolled into EP0012, the Baseline absence, and/or myoclonic seizure data from SP0982's 4-week Prospective Baseline Period were combined with any reported Baseline absence, and myoclonic seizure information in the daily seizure diary from EP0012 (reported before first dose in EP0012) to recalculate the study participant's Baseline variables such as days with absence, and/or myoclonic seizures per 28 days. |

Percentage of Study Participants With Treatment-emergent Marked Abnormalities (TEMAs) in 12-lead ECG Parameter (Heart Rate Interval) |
TEMA values are defined in the SAP as significant deviations from the expected range of age-appropriate values. TEMA ECG results of Heart rate interval were those that were observed post- BL during the Treatment Period but not present at Baseline. For the age range, '3 years -<12 years', the abnormality criteria were '<60 beats per minute (bpm)' (Abn A) and '>130 bpm' (Abn B). For the age range, '>=12 years', the abnormality criteria were '<50 bpm' (Abn C) and '>120 bpm' (Abn D). |

Percentage of Study Participants With Treatment-emergent Marked Abnormalities (TEMAs) in Vital Sign Measurements (Pulse Rate) |
TEMA values are defined in the SAP as significant deviations from the expected range of age-appropriate values. TEMA vital signs results of Pulse rate were those that were observed post- BL during the Treatment Period but not present at Baseline. For the age range, '3 years -<12 years', the abnormality criteria were '<60 bpm' (Low) and '>130 bpm' (High). For the age range, '12 years - <17 years', the abnormality criteria were '<=50 bpm' (Low) and '>=120 bpm' (High). For the age range, '>=17 years', the abnormality criteria were '<=50 bpm and a decrease from Baseline of >=15 bpm' (Low A), '>=120 bpm and an increase from Baseline of >=15 bpm' (High A), '<60 bpm' (Low B) and '>100 bpm' (High B). The Pulse rate was reported as per positions such as 'Supine 3 minute (Sup 3 min)', 'Standing 1 minute' (Std 1 min), and 'Standing 3 minute' (Std 3 min). |

Percentage of Study Participants With Treatment-emergent Marked Abnormalities (TEMAs) in Vital Sign Measurements (Systolic Blood Pressure) |
TEMA values of Systolic Blood Pressure (BP) results were those that were observed post- BL during the Treatment Period but not present at Baseline. For the age range, '3 years -<12 years', the abnormality criteria were '<80 millimeters of mercury (mmHg)' (Low) and '>140 mmHg' (High). For the age range, '>=12 years - <17 years', the abnormality criteria were '<90 mmHg' (Low) and '>160 mmHg' (High). For the age range, '>=17 years', the abnormality criteria were '<=90 mmHg and decrease from Baseline of >=20 mmHg' (Low A), '>=180 mmHg and increase from Baseline of >=20' mmHg (High A), '<90 mmHg' (Low B), '>140 mmHg (High B), and '>160 mmHg' (High C). Systolic BP were reported as per positions such as 'Sup 3 min', 'Std 1 min, and 'Std 3 min'. |

Percentage of Study Participants With Treatment-emergent Marked Abnormalities (TEMAs) in Vital Sign Measurements (Diastolic Blood Pressure) |
TEMA values of Diastolic BP results were those that are observed post- BL during the Treatment Period but not present at Baseline. For the age range, '3 years -<12 years', the abnormality criteria were '<50 mmHg' (Low) and '>80 mmHg' (High), '>=12 years - <17 years', the abnormality criteria were '<=50 mmHg' (Low) and '>=105 mmHg' (High), and '>=17 years', the abnormality criteria were '<=50 mmHg and decrease from Baseline of >=15 mmHg' (Low A), '>=105 mmHg and increase from Baseline of >=15' mmHg (High A), '<50 mmHg' (Low B), '>90 mmHg' (High B), and '>100 mmHg' (High C). Diastolic BP were reported as per positions such as 'Sup 3 min', 'Std 1 min, and 'Std 3 min'. |

Percentage of Study Participants With Treatment-emergent Marked Abnormalities (TEMAs) in Vital Sign Measurements (Body Weight) |
TEMA values are defined in the SAP as significant deviations from the expected range of age-appropriate values. TEMA vital signs parameter results were those that are observed post- BL during the Treatment Period but not present at Baseline. For the age range, '1 month - <17 years', the abnormality criteria were '<3% of normal body weight' in Kilograms (kg) or '>97% of normal body weight' in kgs. Here, '<3% of normal' is presented as 'Low' and '>97% of normal' is presented as 'High'. For the age range '>=17 years', the abnormality criteria were 'Increase/decrease of >=10%' body weight in kgs (presented as Inc/Dec A) or 'Increase/decrease of >=7%' body weight in kgs (presented as Inc/Dec B). |

Percent Change in Primary Generalized Tonic-clonic Seizure (PGTCS) Frequency Per 28 Days From Combined Baseline |
The 28-day PGTCS frequency during the relative period was subtracted from the 28-day Combined Baseline PGTCS frequency and the result was divided by 28-day Combined Baseline PGTCS frequency and the result was then multiplied by 100 to get percent change in PGTCS frequency per 28 days from Combined Baseline Period (CB) to the appropriate analysis Period. The CB was defined as the combined 12-week Historical Baseline and 4-week Prospective Baseline periods immediately prior to randomization in the study SP0982 or prior to Visit 1 (first dose) if direct enrollers in EP0012. |
From Combined Baseline until end of Treatment Period (up to approximately 5 years) |
