About this study

Official title: Prospective, Non-randomized, Open-label, Mono-centric, Cohort Study on the Absorption of Oral Rivaroxaban in Patients With a Cervical Spinal Cord Injury

The primary objective of this study is to investigate the pharmacokinetic and -dynamic properties of rivaroxaban after oral administration in cervical spinal cord injury (SCI) individuals.

The secondary objective of this study is to determine the steady-state rivaroxaban activity in cervical SCI individuals under long-term therapy.

Primary Objective In-house patients will be informed concerning the study and informed consent will be collected.

During the screening day, in- / exclusion criteria will be assessed and a blood samples will be taken for assessing haematology, clinical chemistry and coagulation parameters. Furthermore, the evaluation day will be scheduled.

On the evaluation day, in- / exclusion criteria will be re-assessed. A venous catheter will be introduced into a forearm or lower leg of each participant for the collection of blood at the specified time points. Skin inspection for subcutaneous bleeding will be performed and vital signs will be recorded. A blood sample will be taken for assessing haematology, clinical chemistry and coagulation parameters.

Single administration of oral rivaroxaban in the form of Xarelto® 10mg tablets (Bayer Schering Pharma, Berlin, Germany).

Rivaroxaban concentrations will be determined from plasma samples taken before, 30min after and 1, 2, 3, 4, 5, 6, 8, 12, 24 hours after rivaroxaban administration. Rivaroxaban activity will be determined from plasma samples taken before, 30min after and 1, 2, 3, 4, 5, 6, 8, 12, 24 hours after rivaroxaban administration using a factor Xa inhibition test and measuring prothrombin time (PT) and activated partial thromboplastin time (aPTT).

Skin inspection for subcutaneous bleeding and measurements of vital signs will be performed 30min and 1, 2, 3, 4, 5, 6, 8, 12 and 24 hours after rivaroxaban administration.

Secondary Objective Patients under long-term rivaroxaban therapy will be recruited during their annual check-up visit at the Swiss Paraplegic Centre. In- / exclusion criteria will be assessed, and the patients will be informed concerning the study and informed consent will be collected.

Blood samples will be taken for assessing haematology, clinical chemistry and coagulation parameters, and skin inspection for subcutaneous bleeding and measurements of vital signs will be performed.

A blood sample (4.3ml citrated venous blood) will be taken for assessing the primary and secondary outcome parameters.

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing Rivaroxaban Oral Tablet in people with Spinal Cord Injuries and Thromboembolism, run by Swiss Paraplegic Research, Nottwil at 1 site in Switzerland.

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 14 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: withdrawn, as of the sponsor's last update on 22 Jan 2019. 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 Switzerland. 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.

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 was withdrawn before enrolling participants, so there are no results.

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?

rivaroxaban plasma level (time frame: before drug administration and 30min, 1h, 2h, 3h, 4h, 5h, 6h, 8h, 12h and 24h after drug administration). 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 Jan 2019.
