    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.

Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

- Subject must have completed or be an eligible Baseline failure from the parent study (SP0982 [NCT02408523]). Note: Other subjects screened for SP0982 may be considered for roll-over to EP0012 if the investigator considers that the subject could benefit from treatment with open-label lacosamide (LCM) and based on prior discussion with and approval from the UCB Study Physician or representative

Exclusion Criteria:

  • Subject is receiving any investigational drugs or using any experimental devices in addition to lacosamide (LCM)
  • Subject meets the withdrawal criteria for SP0982 or is experiencing an ongoing serious adverse event (SAE)
  • Subject has an active suicidal ideation as indicated by a positive response ("Yes") to either Question 4 or Question 5 of the "Since Last Visit" version of the Columbia-Suicide Severity Rating Scale (C-SSRS)
  • Subject has >=2x upper limit of normal (ULN) of any of the following: alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), or >ULN total bilirubin (≥1.5xULN total bilirubin if known Gilbert's syndrome). If subject has elevations only in total bilirubin that are >ULN and <1.5xULN, fractionate bilirubin to identify possible undiagnosed Gilbert's syndrome (ie, direct bilirubin <35%). For all subjects who entered EP0012 directly with a Baseline result >ULN for ALT, AST, ALP, or total bilirubin, a Baseline diagnosis and/or the cause of any clinically meaningful elevation must be understood and recorded in the electronic Case Report form (eCRF). Tests that result in ALT, AST, or ALP up to 25% above the exclusion limit may be repeated once for confirmation.

Individual Participant Data (IPD) Sharing Statement:
Plan to Share IPD: Yes
Plan Description: Data from this trial may be requested by qualified researchers six months after product approval in the US and/or Europe, or global development is discontinued, and 18 months after trial completion. Investigators may request access to anonymized individual patient-level data and redacted trial documents which may include: analysis-ready datasets, study protocol, annotated case report form, statistical analysis plan, dataset specifications, and clinical study report. Prior to use of the data, proposals need to be approved by an independent review panel at www.Vivli.org and a signed data sharing agreement will need to be executed. All documents are available in English only, for a prespecified time, typically 12 months, on a password protected portal. This plan may change if the risk of re-identifying trial participants is determined to be too high after the trial is completed; in this case and to protect participants, individual patient-level data would not be made available.
