Arm description

Participants included in this treatment group received at least one dose of LCM as EP0012 protocol entry criteria. The dose range for pediatric participants weighing <50 kg is from 4 mg/kg/day (oral solution) to 12 mg/kg/day (oral solution), for pediatric participants weighing ≥50 kg, the dose range is from 200 mg/day (tablets) to 600 mg/day (tablets) and for adult participants, the dose range is from 200 mg/day to 800mg/day (tablets) during the Treatment Period. The LCM dose may be increased or decreased at the investigator’s discretion after the study participant received the first dose of LCM in the study. Pediatric participants who initially started on oral solution might have transferred to tablets at Investigator’s discretion after achieving >=50 kgs. LCM was administered orally, twice daily (bid), up to approximately 5 years. Treatment was continued for at least 2 years for adult participants and up to approximately 5 years for pediatric participants.

End point description

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. The Safety Set included all study participants who received at least 1 dose of IMP during this study.

Percentage of study participants with treatment-emergent marked abnormalities (TEMAs) in vital sign measurements (Systolic Blood Pressure)

End point description

TEMA values of Systolic Blood Pressure (BP) results were those that were observed post- BL during the Treatment Period but not present at BL. For age range, ‘3 years -<12 years’, abnormality criteria were ‘<80 millimeters of mercury (mmHg)’ (Low) and ‘>140 mmHg’ (High). For age range, ‘>=12 years - <17 years’, abnormality criteria were ‘<90 mmHg’ (Low) and ‘>160 mmHg’ (High). For age range, ‘>=17 years’, abnormality criteria were ‘<=90 mmHg and decrease from BL of >=20 mmHg’ (Low A), ‘>=180 mmHg and increase from BL 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’. Safety Set was analyzed. N= participants who were evaluable for assessment. ‘n’= signifies participants who were evaluable at specified time points. Data for visits wherein at least 1 TEMA value of Systolic BP observed during study were reported in this assessment.

Percentage of study participants with treatment-emergent marked abnormalities (TEMAs) in vital sign measurements (Body Weight)

End point description

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). Safety Set was analyzed. N= participants who were evaluable for the assessment. ‘n’= participants who were evaluable at specified time points. Data for visits wherein at least 1 TEMA body weight value observed during the study were reported in this assessment.

Percent change in Primary Generalized Tonic-clonic seizure (PGTCS) frequency per 28 days from Combined Baseline

End point description

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. Full Analysis Set (FAS) was a subset of the Safety Set and included all study participants with seizure diary data for at least 1 day during this study.

Were there any global substantial amendments to the protocol? Yes

27 Jan 2015

Global Protocol Amendment 1, dated 27 Jan 2015, provided the following primary and key revisions. No study participants entered the study prior to the date of amendment. The primary purpose of this substantial amendment followed the amendment made to the SP0982 protocol, which was to identify significant changes to the study design and the inclusion of pediatric study participants (≥4 to 12 years of age). The duration of EP0012 was clarified as at least 2 years, and LCM plasma concentration analysis was removed. Clarification on study participants being able to participate in a substudy at some sites, without being withdrawn from EP0012, was added. The use of concomitant medications and treatments was clarified and permitted and prohibited concomitant treatments were clarified to be consistent with SP0982. For pediatric study participants <50 kg, a Dispensation Visit was added 12 weeks after each 24-weekly visit from Year 3 onwards, in order to dispense LCM solution. Behavior Rating Inventory of Executive Function® - Preschool Version (BRIEF®-P) was added and socio-professional data assessment was removed in this study.

09 Jun 2016

Global Protocol Amendment 2, dated 09 Jun 2016, provided the following primary and key revisions. Thirty study participants entered the study prior to the date of amendment. The protocol was amended following a request from the Taiwanese Ministry of Health and Welfare: for dose escalation, study participants who were eligible Baseline failures from SP0982 had to remain on the dose for ≥7 days before a subsequent dose escalation. Additionally, the purpose of the amendment was to remove superfluous description of a substudy, to clarify the requirement for ECG at subsequent visits, requirement for endocrinology and timing of endocrinology assessments, pregnancy testing, definition of contraceptive methods, and seizure count, and to add a definition of the Enrolled Set (ES). Several assessments were removed from Years 3 to 5, including brief physical examination (complete physical examination instead), complete neurological examination (brief neurological examination instead), and health outcome measures. The protocol was also updated according to the new UCB protocol template, for example, with the addition of text regarding potential drug-induced liver injury (PDILI).

29 Nov 2017

Global Protocol Amendment 3, dated 29 Nov 2017, provided the following primary and key revisions. One hundred forty-four study participants entered the study prior to the date of amendment. The primary purpose of this amendment was to simplify the assessments and procedures for all study participants during the first 94 weeks of study and to simplify the assessments and procedures for adults after Week 94. Pediatric assessments were kept as they were after Week 94 for regulatory purposes. In addition, the following changes were made: • To allow the Safety Follow-up for study participants tapered in SP0982 after the 125th event occurred in SP0982; the 4-week Safety Follow-up was to be started at Visit 1 of EP0012. • In the schedule of study assessments for treatment Years 1 to 2, a footnote was added to explain that Visit 6, Visit 7, and Visit 10 were not performed according to Protocol Amendment 3. Footnote ‘b’ had ‘vital signs’ removed and for footnote ‘d,’ Week 30, Week 38, and Week 78 were added to the footnote for consistency. • A schedule of study assessments for Years 3 through 5 for EP0012 (Treatment Period, Early Termination (ET) Visit, Termination Visit, and Unscheduled Visit for study participants ≥18 years) was added. • In the schedule of study assessments for Years 3 through 5, footnotes were amended to specify that the Taper Period and Safety Follow-up Visit included some of the study participants who tapered into SP0982 after the 125th event and who consented to enter EP0012 for the Safety Follow-up Visit only. • To restructure the safety variables. • To align the planned number of study participants with the pivotal study SP0982. • To update the introduction section with regulatory information on the marketing authorization of Vimpat and to provide an update on the LCM clinical program. • To clarify the PDILI criteria requiring immediate and permanent discontinuation of the study medication.

13 Dec 2019

Global Protocol Amendment 4, dated 13 Dec 2019, provided the following primary and key revisions. All study participants entered the study prior to the date of amendment. The primary purpose of this substantial amendment was to extend the treatment of the study participants and have LCM available for the study participants till the main approvals for an extended PGTCS indication was obtained. UCB sought to obtain the approvals in first instance in US, EU, and Japan. In addition, primary generalized tonic-clonic seizures was globally changed to PGTCS.
