Bioequivalence Study of Two Brivaracetam Oral Solutions in Healthy Adults Under Fasting and High-Fat Meal Conditions (BE)

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 is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Maximum Plasma Concentration (Cmax)
Time Frame: two weeks
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.
two weeks
Area Under the Plasma Concentration-Time Curve from Time 0 to Last Measurable Concentration (AUC0-t)
Time Frame: two weeks
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.
two weeks
Area Under the Plasma Concentration-Time Curve from Time 0 to Infinity (AUC0-∞)
Time Frame: two weeks
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.
two weeks

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Time to Reach Maximum Plasma Concentration(Tmax )
Time Frame: two weeks
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.
two weeks
Terminal Elimination Rate Constant (λz)
Time Frame: two weeks
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.
two weeks
Half-life (t1/2)
Time Frame: two weeks
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.
two weeks
Percentage of the Area Under the Curve Extrapolated to Infinity(AUC_%Extrap )
Time Frame: two weeks
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.
two weeks
