Outcomes Module
Primary Outcomes
Measure
Description
Time Frame
Change in Log-transformed Observable Focal Onset Seizure Frequency From Baseline Over the 12 Week Maintenance Period
During the study, participants kept diaries to record daily seizure activity. Seizure frequency refers to 28-day adjusted frequency. Seizure frequency was based on investigator assessment of participants' reports of daily seizure type and frequency. Observable focal-onset seizures refer to Type IA1, IB, and IC (ILAE Classification of Epileptic Seizures, 1981). Based on ANCOVA on change in log-transformed, 28-day adjusted seizure frequency from Baseline with treatment group as the main factor, Baseline log-transformed seizure frequency as a continuous covariate, Baseline SV2A use (yes or no) and Region (Europe, Non-Europe) as categorical factors.
From Baseline over the 12 Week Maintenance Period
Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs) Reported by the Subject and/or Caregiver or Observed by the Investigator During the Entire Study
An Adverse Event is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment.
From Baseline until Safety Follow-Up (up to Week 23)
Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs) Leading to Study Withdrawal
An Adverse Event is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment.
From Baseline until Safety Follow-Up (up to Week 23)
Percentage of Participants With Treatment-Emergent Serious Adverse Events (SAEs) During the Entire Study
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 an 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 Outcomes

Description
Time Frame
75 % Responder Rate Over the 12 Week Maintenance Period
The 75% responder rate, where a responder is a participant experiencing a ≥75% reduction in observable focal-onset seizure frequency from Baseline, over the 12-Week Maintenance Period.
End of Maintenance Period (Week 16) following 3 Weeks of titration and 1 Week stabilization

Eligibility Module
Eligibility Criteria
Inclusion Criteria:
Diagnosis of focal epilepsy per 1989 International League Against Epilepsy (ILAE) criteria at least 3 years before study entry
Subject has failed to achieve seizure control with 4 tolerated and appropriately chosen prior antiepileptic drugs (AED), including past and ongoing treatment, that were individually optimized for adequate dose and duration. Prior discontinued AED treatment would need to be assessed by the Investigator considering the patient medical records and patient and/or caregiver interview. 'Prior AED' is defined as all past and ongoing AED treatments with a start date before the Screening Visit (Visit 1)
Average of >= 4 spontaneous and observable focal seizures (type IA1 (i.e. focal aware), IB (i.e. focal impaired awareness), IC (i.e. focal to bilateral tonic-clonic)) per month
Current treatment with an individually optimized and stable dose of at least 1 and up to 3 AEDs for the 8 weeks prior to the Screening Visit with or without additional Vagus Nerve Stimulation (VNS) or other neurostimulation treatments
Exclusion Criteria:
Subject has a history of or signs of generalized or combined generalized and focal epilepsy
Cluster seizures which are uncountable in the previous 8 weeks before study entry and during 4 weeks prospective baseline
Current treatment with carbamazepine, phenytoin, primidone, phenobarbital
Current treatment/ use of (non-AED) prescription, nonprescription, dietary (eg, grapefruit or passion fruit), or herbal products that are potent inducers or inhibitors of the CYP3A4 or 2C19 pathway for 2 weeks (or 5 half-lives, whichever is longer) prior to the Baseline Visit
Subjects taking sensitive substrates of CYP2C19 for 2 weeks (or 5 half-lives, whichever is longer) prior to the Baseline Visit
Subject has been taking vigabatrin less than 2 years at study entry
Subject has been taking felbamate for less than 12 months
Subject taking retigabine for less than 4 years
Current treatment with benzodiazepines (i.e. GABA-A-ergic drugs like zolpidem, zaleplon, or zopiclone, excluding GABA-A-ergic AEDs) <3 times per week for emergencies
Subject has a current medical condition that occurred within the last 12 months which, in the opinion of the investigator, could compromise his/her safety or ability to participate in this study

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.

Time Frame
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.
Access Criteria
Qualified researchers may request access to anonymized IPD and redacted study documents which may include: raw datasets, analysis-ready datasets, study protocol, blank case report form, 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 pre-specified time, typically 12 months, on a password protected portal.
The study included: a 4-week Baseline Period, a 16-week Treatment Period, a 4-week Taper Period (for participants who discontinued or choose not to enroll in the open-label extension study) and a Safety Follow-up Period. Participants continuing to the OLE study had a 3-week Conversion Period.
Participant Flow refers to the Randomized Set.
Recruitment Details
The study started to enroll patients in February 2018 and concluded in January 2020.

Change in Log-transformed Observable Focal Onset Seizure Frequency From Baseline Over the 12 Week Maintenance Period
During the study, participants kept diaries to record daily seizure activity. Seizure frequency refers to 28-day adjusted frequency. Seizure frequency was based on investigator assessment of participants' reports of daily seizure type and frequency. Observable focal-onset seizures refer to Type IA1, IB, and IC (ILAE Classification of Epileptic Seizures, 1981). Based on ANCOVA on change in log-transformed, 28-day adjusted seizure frequency from Baseline with treatment group as the main factor, Baseline log-transformed seizure frequency as a continuous covariate, Baseline SV2A use (yes or no) and Region (Europe, Non-Europe) as categorical factors.
The Full Analysis Set (FAS) consisted of all study participants in the RS who were administered at least 1 dose or a partial dose of IMP and had Baseline and at least 1 post-Baseline seizure frequency data during the 16-week Treatment Period.

OG001
Dose group comparisons to Placebo p-value were based on the Wilcoxon-Mann-Whitney test. The Hodges-Lehmann nonparametric estimator was used to estimate the median difference between each PSL dose group versus placebo, along with the corresponding 95% CI of the estimate.
