About this study

Official title: Estimate of Costs Associated With Atrial Fibrillation Treatment With Rivaroxaban Versus Vitamin K Antagonists

The main objective of this project is to evaluate savings in direct costs as regards the use of rivaroxaban versus vitamin K antagonists (VKAs) in routine clinical practice using data from three cohorts of patients receiving VKAs or rivaroxaban in Spain, including the time in therapeutic range (TTR) values of the same and the incidence of events in the first year following diagnosis.

Being tested
Rivaroxaban (Xarelto, BAY59-7939), Vitamin K antagonists (VKAs)
Keywords

Questions about this trial

What is this clinical trial studying?

An observational study of Atrial Fibrillation, run by Bayer at 1 site in Spain.

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 1 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 12 Mar 2018. 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 Spain. 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.

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?

Time in therapeutic range (TTR) values in the last 6 months (time frame: 6 months). 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 12 Mar 2018.
