Who cannot join

  • Participant has any medical or psychiatric condition that, in the opinion of the Investigator, could jeopardize or compromise the study participant's ability to participate in this study, such as a history of schizophrenia, or other psychotic disorder, bipolar disorder, or severe unipolar depression. The presence of potential psychiatric exclusion criteria will be determined based on the psychiatric history collected at Screening Visit
  • Participant has a known hypersensitivity to any components of the study medication as stated in this protocol
  • Participant has a lifetime history of suicide attempt (including an actual attempt, interrupted attempt, or aborted attempt), or has had suicidal ideation in the past 6 months
  • Participant has past or intended use of over-the-counter or prescription medication including herbal remedies and hepatic enzyme inhibitors within 2 weeks or 5 half-lives prior to dosing, particularly for participants with hepatic impairment where t1/2 may be prolonged. Specific medications may be allowed. Participant has used hepatic enzyme-inducing drugs (eg, glucocorticoids, phenobarbital, phenytoin, isoniazid, or rifampicin, etc.) within 2 months prior to dosing unless required to treat an adverse event (AE). This does not include oral contraceptives not exceeding 30 μg ethinyl estradiol or postmenopausal hormone replacement therapy (HRT) or implants, patches, or intrauterine devices (IUDs) /intrauterine systems (IUSs) delivering progesterone (for female study participants) or acetaminophen with a maximal dose of 2 g/day or with a maximum of 10g over 15 days.

What is being measured

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

  1. Maximum Plasma Concentration (Cmax) of a Single Dose Padsevonil (PSL)

    Cmax is maximum observed plasma concentration.

    Measured: Plasma samples were taken predose on Day 1 and 0.25, 0.5, 0.75, 1, 1.5, 3, 4, 5, 6, 8, 12, 24, 48, 72 and 96 hours postdose

  2. Area Under the Plasma Concentration-time Curve From Time 0 to t (AUC0-t) of a Single Dose Padsevonil (PSL)

    AUC (0-t) is defined as area under the plasma concentration-time curve from time zero to time t.

    Measured: Plasma samples were taken predose on Day 1 and 0.25, 0.5, 0.75, 1, 1.5, 3, 4, 5, 6, 8, 12, 24, 48, 72 and 96 hours postdose

  3. Area Under the Plasma Concentration-time Curve (AUC) From Time 0 to Infinity of a Single Dose Padsevonil (PSL)

    AUC is defined as area under the plasma concentration-time curve from time 0 to infinity.

    Measured: Plasma samples were taken predose on Day 1 and 0.25, 0.5, 0.75, 1, 1.5, 3, 4, 5, 6, 8, 12, 24, 48, 72 and 96 hours postdose

  4. Maximum Observed Plasma Concentration at Steady-state (Cmax,ss) of Multiple Doses Padsevonil (PSL)

    Cmax,ss is defined as maximum observed plasma concentration at steady-state.

    Measured: On Days 8, 9, 10 and 11 PK samples were taken predose. On Day 12, PK samples were taken predose and 0.25, 0.5, 0.75, 1, 1.5, 3, 4, 5, 6, 8, 12, 24 hours postdose

  5. Area Under the Concentration-time Curve (AUCtau) at Steady-state Over a Dosing Interval of Multiple Doses Padsevonil (PSL)

    AUCtau is defined as area under the curve over a dosing interval at steady-state.

    Measured: On Days 8, 9, 10 and 11 PK samples were taken predose. On Day 12, PK samples were taken predose and 0.25, 0.5, 0.75, 1, 1.5, 3, 4, 5, 6, 8, 12, 24 hours postdose

Secondary outcomes (3)
  1. Number of Participants With Treatment-emergent Adverse Events (TEAEs)

    An Adverse Event (AE) is any untoward medical occurrence in a patient or clinical investigation subject administered a pharmaceutical product, which does not necessarily have a causal relationship with this treatment. A treatment-emergent adverse event was characterized according to the intake of the study medication.

    Measured: From Baseline until End of Study Visit (up to Day 18)

  2. Number of Participants With Serious Adverse Events (SAEs)

    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.

    Measured: From Baseline until End of Study Visit (up to Day 18)

  3. Number of Participants With Treatment-emergent Adverse Events (TEAEs) Leading to Discontinuation of the Study

    An adverse event (AE) 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. A treatment-emergent adverse event was characterized according to the intake of the study medication. TEAEs leading to discontinuation of the study are reported.

    Measured: From Baseline until End of Study Visit (up to Day 18)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Padsevonil in people with Healthy Study Participants and Impaired Hepatic Function, run by UCB Biopharma S.P.R.L. at 1 site in United States.

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 8 inclusion and 16 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 28 Jul 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 28 Jul 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?

Maximum Plasma Concentration (Cmax) of a Single Dose Padsevonil (PSL) (time frame: Plasma samples were taken predose on Day 1 and 0.25, 0.5, 0.75, 1, 1.5, 3, 4, 5, 6, 8, 12, 24, 48, 72 and 96 hours postdose). The study lists 5 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 28 Jul 2021.
