About this study

Official title: Single-dose, Open-label, Randomized, 2-way Crossover Pivotal Bioequivalence Study of 2x5 mg Tablets Rivaroxaban Versus 1x10 mg Tablet Rivaroxaban Under Fasted Condition in Healthy Subjects

The drug investigated in this study is Rivaroxaban, a novel, once-daily, oral anticoagulant for the prevention (prophylaxis) of deep vein thrombosis (DVT) which may lead to a pulmonary embolism (PE) in people undergoing knee or hip replacement surgery.

The purpose of this study is to establish bioequivalence of 2 immediate-release tablet treatments with Rivaroxaban: 2*5 mg tablets and 1*10 mg tablet will be given to healthy volunteers under fasting conditions; they will be administered as single oral doses in 2 periods. Both periods will be separated by a 7-day washout phase. Thus, the bioequivalence represents the primary study objective. As a secondary objective, this treatment will be assessed in terms of safety and tolerability.

Bioequivalence will be evaluated and verified on the basis of pharmacokinetic data. Blood samples of the volunteers will be taken at specific points in time; these samples will be analyzed using various statistical methods to establish pharmacokinetic characteristics required to compare the 2 treatments. The planned treatments with Rivaroxaban will be considered bioequivalent if specific criteria defined in the study protocol are met.

The study will be conducted in one center in Germany. 28 subjects meeting the inclusion criteria will participate. They will be treated according to a single-dose, randomized, 2-way cross-over, non-placebo-controlled design.

What is being measured

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

  1. Area Under the Plasma Concentration Versus Time Curve From Time Zero to Infinity After Single Dose (AUC) Incl. Bioequivalence (BE) Evaluation

    The AUC is a measure of systemic drug exposure, which is obtained by collecting a series of blood samples and measuring the concentrations of drug in each sample (AUC is defined as area under the concentration vs. time curve from zero to infinity after single (first) dose).

    Measured: 0 min, 15 min, 30 min, 45 min, 1 hour, 1.5 hours, 2 hours, 2.5 hours, 3 hours, 4 hours, 6 hours, 8 hours, 12 hours, 15 hours, 24 hours, 36 hours, 48 hours and 72 hours post administration

  2. Area Under the Plasma Concentration Versus Time Curve From Time Zero to Last Quantifiable Concentration [AUC (0-tn)] Incl. Bioequivalence (BE) Evaluation

    The AUC is a measure of systemic drug exposure, which is obtained by collecting a series of blood samples and measuring the concentrations of drug in each sample; [AUC (0-tn)] is defined as AUC from time 0 to the last data point above the Lower Limit of Quantification.

    Measured: 0 min, 15 min, 30 min, 45 min, 1 hour, 1.5 hours, 2 hours, 2.5 hours, 3 hours, 4 hours, 6 hours, 8 hours, 12 hours, 15 hours, 24 hours, 36 hours, 48 hours and 72 hours post administration

  3. Maximum Observed Drug Concentration in Plasma After Single Dose Administration (Cmax) Incl. Bioequivalence (BE) Evaluation

    Cmax refers to the highest measured drug concentration which is obtained by collecting a series of blood samples and measuring the concentrations of drug in each sample.

    Measured: 0 min, 15 min, 30 min, 45 min, 1 hour, 1.5 hours, 2 hours, 2.5 hours, 3 hours, 4 hours, 6 hours, 8 hours, 12 hours, 15 hours, 24 hours, 36 hours, 48 hours and 72 hours post administration

Secondary outcomes (5)
  1. Area Under the Plasma Concentration Versus Time Curve Divided by Dose Per kg Body Weight (AUCnorm)

    The AUC is a measure of systemic drug exposure, which is obtained by collecting a series of blood samples and measuring the concentrations of drug in each sample; AUCnorm is defined as AUC divided by dose per kg body weight.

    Measured: 0 min, 15 min, 30 min, 45 min, 1 hour, 1.5 hours, 2 hours, 2.5 hours, 3 hours, 4 hours, 6 hours, 8 hours, 12 hours, 15 hours, 24 hours, 36 hours, 48 hours and 72 hours post administration

  2. Maximum Observed Drug Concentration in Plasma After Single Dose Administration Divided by Dose Per kg Body Weight (Cmax, Norm)

    Cmax refers to the highest measured drug concentration which is obtained by collecting a series of blood samples and measuring the concentrations of drug in each sample; Cmax,norm is defined as Cmax divided by dose (mg) per kg body weight.

    Measured: 0 min, 15 min, 30 min, 45 min, 1 hour, 1.5 hours, 2 hours, 2.5 hours, 3 hours, 4 hours, 6 hours, 8 hours, 12 hours, 15 hours, 24 hours, 36 hours, 48 hours and 72 hours post administration

  3. Mean Residence Time (MRT)

    The mean residence time is the average time that the molecules introduced into the body stay in the body.

    Measured: 0 min, 15 min, 30 min, 45 min, 1 hour, 1.5 hours, 2 hours, 2.5 hours, 3 hours, 4 hours, 6 hours, 8 hours, 12 hours, 15 hours, 24 hours, 36 hours, 48 hours and 72 hours post administration

  4. Time to Reach Maximum Drug Concentration in Plasma After Single Dose (Tmax)

    Tmax refers to the time after dosing when a drug attains its highest measurable concentration (Cmax). It is obtained by collecting a series of blood samples at various times after dosing, and measuring them for drug content.

    Measured: 0 min, 15 min, 30 min, 45 min, 1 hour, 1.5 hours, 2 hours, 2.5 hours, 3 hours, 4 hours, 6 hours, 8 hours, 12 hours, 15 hours, 24 hours, 36 hours, 48 hours and 72 hours post administration

  5. Half-life Associated With the Terminal Slope (t½)

    Half-life refers to the elimination of the drug, i.e. the time it takes for the blood plasma concentration to reach half the concentration in the terminal phase of elimination.

    Measured: 0 min, 15 min, 30 min, 45 min, 1 hour, 1.5 hours, 2 hours, 2.5 hours, 3 hours, 4 hours, 6 hours, 8 hours, 12 hours, 15 hours, 24 hours, 36 hours, 48 hours and 72 hours post administration

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Rivaroxaban (Xarelto, BAY59-7939) in people with Therapeutic Equivalency, run by Bayer at 1 site in Germany.

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 7 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 22 Apr 2015. 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 Germany. 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 22 Dec 2011). 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?

Area Under the Plasma Concentration Versus Time Curve From Time Zero to Infinity After Single Dose (AUC) Incl. Bioequivalence (BE) Evaluation (time frame: 0 min, 15 min, 30 min, 45 min, 1 hour, 1.5 hours, 2 hours, 2.5 hours, 3 hours, 4 hours, 6 hours, 8 hours, 12 hours, 15 hours, 24 hours, 36 hours, 48 hours and 72 hours post administration). 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 22 Apr 2015.
