About this study

Official title: Bioequivalence of Abiraterone Acetate in Healthy Chinese Volunteers: an Open, Randomized, Single-dose, Three-cycle, Three-sequence Crossover Study

An open, randomized, single-dose, three-cycle, three-sequence crossover study was conducted in 36 healthy volunteers under fasting condition to evaluate the bioequivalence of two abiratone acetate tablets.

Read the detailed description

Abiraterone acetate tablet is an androgen synthesis inhibitor, primarily for the treatment of mCRPC. The objective of this study was to evaluate the pharmacokinetics and bioequivalence of two abiraterone acetate tablets in healthy Chinese subjects. In healthy subjects, a single-center, open, single-dose, randomized, three-cycle, three-sequence, semi-repeat (duplicate reference preparation only), reference formulation corrected fasting mean bioequivalence trial was conducted with a minimum of 7 days cleaning period between dosing.

Blood samples were collected at prescribed time intervals, and the plasma concentration of abiraterone acetate tablet was determined by liquid chromatography-tandem mass spectrometry and adverse events were recorded.

The pharmacokinetic parameters Cmax, Tmax, AUC0-t, AUC0-∞, T1/2 and so on were calculated by non-atrioventricular model. When the individual coefficient of variation(CVWR) of the pharmacokinetic parameters (AUC0-t, AUC0-∞ and Cmax) of reference formulation was less than 30%,with an average bioequivalence (ABE) criterion: if the test formulation and reference formulation of pharmacokinetic parameters (AUC0 - t,AUC0-∞ and Cmax) of the 90% CIs of GMR is not beyond the range of 80.00% -125.00%, which can determine the test formulation and reference formulation have bioequivalence.When the CVWR of the pharmacokinetic parameters (AUC0-t, AUC0-∞ and Cmax) of the reference preparation is greater than or equal to 30%,the reference preparation was used to correct for mean bioequivalence (RSABE): if the critbound of the pharmacokinetic parameters (AUC0-t,AUC0-∞ , Cmax) of the test formulations and reference formulations is less than 0, and the geometric average ratio is not beyond the range of 0.8000 - 1.2500, which can determine the test formulation and reference formulation have bioequivalence.

What is being measured

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

  1. the ratios of geometrical mean

    The two formulations are considered to be bioequivalent if the CVWR is less than 30% and 90% CIS of the ratio of primary pharmacokinetic parameters is within a predetermined acceptance range of 80% to 125%. If the CVWR of the pharmacokinetic parameters of the reference preparation is greater than or equal to 30%, Critbound ≤0, and the geometric mean ratio does not exceed the range of 0.8000 to 1.2500, the test preparation and the reference preparation can be determined to be bioequivalent.

    Measured: 30 Days

Secondary outcomes (1)
  1. the occurrence rate of adverse events

    Adverse events were recorded to evaluate the safety of the studied drugs.

    Measured: 30 Days

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Abiraterone acetate tablets(Zecke ®250 mg);Abiraterone acetate tablets(250 mg) in people with Healthy Volunteers, run by The Affiliated Hospital of Qingdao University at 1 site in China.

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 5 inclusion and 15 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: finished, as of the sponsor's last update on 28 Apr 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 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

the ratios of geometrical mean (time frame: 30 Days). 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 NCT04863105, which also lists 1 linked publication.

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 Apr 2021.
