Key requirements

Who can take part, as listed by the sponsor. Only the study team can confirm whether you are eligible, so take this list to your doctor.

  • Ages 18 years and older
  • All sexes
  • No healthy volunteers
  • Adult, Older adult

Who may be able to join

  • Subject is an adult (18 years of age or more )
  • Subject with epilepsy who has completed 1 of the previous Padsevonil (PSL) studies which allow access to the present study
  • Female subjects of child bearing potential must have a serum negative pregnancy test at the Entry Visit, which is confirmed to be negative by urine testing prior to further dispensing at each study visit thereafter. Subjects will be withdrawn from the study as soon as pregnancy is known. Female subjects will use an efficient form of contraception for the duration of the study and for a period of 3 months after their final dose of PSL.

Who cannot join

  • 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 (>= l.5x ULN total bilirubin if known Gilbert's syndrome) at the Entry Visit
  • Subject has a clinically-significant abnormality on electrocardiogram (ECG) that, in the opinion of the investigator, increases the risks associated with participating in the study
  • Subject has an abnormality on echocardiogram at last echocardiogram assessment, or foreseen in parent study as assessed by central reader that is accompanied by clinical symptoms or a Grade 2* (or higher)/moderate severity abnormality, or a history of rheumatic heart disease, or other known valvular abnormalities (*according to the ASE Guidelines, 2017; Zoghbi et al 2017)

About this study

Official title: An Open-Label, Multicenter, Extension Study to Evaluate the Safety and Efficacy of Padsevonil as Adjunctive Treatment of Focal-Onset Seizures in Adult Subjects With Drug-Resistant Epilepsy

The purpose of the study is to evaluate the long-term safety and tolerability of Padsevonil administered at individualized doses as adjunctive treatment for subjects with drug-resistant epilepsy.

Being tested
Padsevonil
Keywords
Drug-Resistant Epilepsy, Padsevonil
Medical subject headings

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • PadsevonilDrug

    • Pharmaceutical Form: film-coated tablet
    • Route of Administration: Oral use
Study groups in NCT03370120
Study groupRoleWhat they receive
PadsevonilExperimentalPadsevonil will be administered in an open-label manner. The individual starting dose of each subject will be the one at the end of the parent study. Once subjects enter EP0093 further individual dose adjustments are allowed after 1 week to the extent possible with the combination of tablet strengths available.
Receives: Drug: Padsevonil

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs) Reported by the Participant and/or Caregiver or Observed by the Investigator During the Entire Study

    An Adverse Event is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment. A TEAE was defined as any event that was not present prior to the initiation of the first dose of study treatment in this study or any unresolved event already present before initiation of the first dose that worsens in intensity following exposure to the treatment.

    Measured: From Entry Visit (Week 0) until the Safety Follow-up Visit (up to approximately 2 years)

  2. Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs) Leading to Study Withdrawal

    An Adverse Event is any untoward medical occurrence in a participant or clinical investigation participant administered a pharmaceutical product that does not necessarily have a causal relationship with this treatment. A TEAE was defined as any event that was not present prior to the initiation of the first dose of study treatment in this study or any unresolved event already present before initiation of the first dose that worsens in intensity following exposure to the treatment.

    Measured: From Entry Visit (Week 0) until the Safety Follow-up Visit (up to approximately 2 years)

  3. Change From Baseline (From the Respective Parent Study [EP0091 or EP0092]) in Observable Focal-onset Seizure Frequency Over the Evaluation Period

    Seizure frequency refers to 28-day adjusted frequency. Observable focal-onset seizures refer to Type IAl, IB, and IC (according to the International League Against Epilepsy (ILAE) Classification of Epileptic Seizures, 1981). Focal-onset seizures include all Type I seizures.

    Measured: From Baseline in respective parent study over the Evaluation Period (up to approximately 2 years) in this study

Individual data sharing
Yes: 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.

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Padsevonil in people with Drug-Resistant Epilepsy and Focal-Onset Seizures, run by UCB Biopharma SRL at 156 sites in 27 countries.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: stopped early, as of the sponsor's last update on 29 Dec 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 156 sites in United States, Spain, Germany, Japan, Poland and 22 more countries. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 29 Dec 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Percentage of Participants With Treatment-Emergent Adverse Events (TEAEs) Reported by the Participant and/or Caregiver or Observed by the Investigator During the Entire Study (time frame: From Entry Visit (Week 0) until the Safety Follow-up Visit (up to approximately 2 years)). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Dec 2021.
