About this study

Official title: A Randomized, Open-Label, Two-Formulation, Two-Period, Crossover Bioequivalence Study of Oral Brivaracetam Solution Administered As a Single Dose Under Fasting and High-fat Meal Conditions in Healthy Subjects

The goal of this clinical trial is to evaluate the bioequivalence of Brivaracetam oral solution under fasting and high-fat meal conditions in healthy adults. The study will compare a test formulation (produced by Jiangsu Chia Tai Fenghai Pharmaceutical Co., Ltd., 300ml: 3g) to the reference formulation (Briviact®, UCB Pharma S.A., 300ml: 3g).

The main questions it aims to answer are:

  1. Do the test and reference formulations of Brivaracetam oral solution exhibit similar pharmacokinetic behavior in the body?
  2. What are the clinical safety outcomes for participants taking the test and reference formulations?

Participants will:

Be randomly assigned to two treatment sequences (T-R or R-T) in a 1:1 ratio. Receive either the test formulation or reference formulation of Brivaracetam oral solution (10ml), taken with 240mL of warm water, under either fasting or high-fat meal conditions.

Cross over to the alternate formulation after a 7-day washout period, completing a total of two treatment periods (2 weeks).

Undergo regular checkups and tests to monitor pharmacokinetics and safety outcomes.

What participants receive

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

  • Brivaracetam Oral Solution (Test Formulation)Drug

    The drug is manufactured by Jiangsu Chia Tai Fenghai Pharmaceutical Co., Ltd. The formulation is provided as a 300 mL: 3 g solution, with a dosage of 10 mL (100 mg) per single oral dose. The drug will be administered to participants in the fasting group during the first phase of the study and to participants in the high-fat meal group during the second phase of the study.

  • Brivaracetam Oral Solution (Reference Formulation)Drug

    Also called Briviact®

    The drug is manufactured by UCB Pharma S.A. under the trade name Briviact®. The formulation is provided as a 300 mL: 3 g solution, with a dosage of 10 mL (100 mg) per single oral dose. The drug will be administered to participants in the fasting group during the first phase of the study and to participants in the high-fat meal group during the second phase of the study.

What is being measured

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

  1. Maximum Plasma Concentration (Cmax)

    Cmax is the maximum observed plasma concentration of the drug following a single oral dose. This parameter reflects the peak exposure to the drug in the bloodstream after administration.

    Measured: two weeks

  2. Area Under the Plasma Concentration-Time Curve from Time 0 to Last Measurable Concentration (AUC0-t)

    AUC0-t represents the total drug exposure from time 0 to the last measurable concentration. It is an important pharmacokinetic parameter for understanding the extent of drug absorption over time.

    Measured: two weeks

  3. Area Under the Plasma Concentration-Time Curve from Time 0 to Infinity (AUC0-∞)

    AUC0-∞ is the area under the plasma concentration-time curve from time 0 to infinity, capturing the total exposure to the drug. It includes all measurable concentrations, both during and after the absorption phase.

    Measured: two weeks

Secondary outcomes (4)
  1. Time to Reach Maximum Plasma Concentration(Tmax )

    Tmax is the time it takes to reach the maximum plasma concentration (Cmax) after a single dose of the drug. It indicates the rate at which the drug is absorbed into the bloodstream.

    Measured: two weeks

  2. Terminal Elimination Rate Constant (λz)

    λz is the terminal elimination rate constant, which is used to describe the rate at which the drug is cleared from the body during the elimination phase. This value helps estimate the half-life of the drug.

    Measured: two weeks

  3. Half-life (t1/2)

    t1/2 is the time required for the plasma concentration of the drug to decrease by half. It is a key pharmacokinetic parameter to understand the duration of action of the drug.

    Measured: two weeks

  4. Percentage of the Area Under the Curve Extrapolated to Infinity(AUC_%Extrap )

    AUC_%Extrap is the percentage of the total AUC that is extrapolated beyond the last measured concentration (AUC∞ - AUC0-t) / AUC∞. This indicates the reliability of the AUC data and how much data is based on extrapolated values.

    Measured: two weeks

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 4 inclusion and 20 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: status not confirmed, as of the sponsor's last update on 8 Jan 2025. 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 China. 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?

Results are not available in the source record.

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) (time frame: two weeks). 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?

On the ClinicalTrials.gov record for NCT06762743, which also lists 5 linked publications.

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 8 Jan 2025.
