What is being measured
The primary outcome is the main question the study is designed to answer.
Persistence rate of newly prescribed apixaban, rivaroxaban, dabigatran and vitamin K antagonists (VKAs) in patients with non-valvular atrial fibrillation(NVAF)
We defined non-persistence in the databases as the absence of index prescription for twice the median prescription duration; and calculated cumulative incidence (95% CIs) of persistence at the end of follow-up and at different time points after treatment initiation (3, 6, and 12 months)
Measured: 23 months for the UK and Germany, 25 months for France
Secondary outcomes (4)
Demographic characteristics (Age, Gender, Smoking status, region of practice, data source) of patients with newly prescribed oral anticoagulants
Measured: 23 months for the UK and Germany, 25 months for France
Clinical characteristics (History of bleeding, myocardial infarction, stroke, Thromboembolism, congestive heart failure, vascular disease, hypertension, CHA2DS2-VASc score, HAS-BLED score, etc) of patients with newly prescribed oral anticoagulants
Measured: 23 months for the UK and Germany, 25 months for France
Adherence to newly prescribed oral anticoagulants based on Medication possession ratio (MPR)
Measured: 23 months for the UK and Germany
Compare persistence rates across oral anticoagulant therapies
Measured: 23 months for the UK and Germany, 25 months for France

Questions about this trial
What is this clinical trial studying?
An observational study of Non-valvular Atrial Fibrillation, run by Bristol-Myers Squibb.
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 2 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 20 Dec 2016. Status can change between updates, so confirm with the study contact before making plans.
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?
Persistence rate of newly prescribed apixaban, rivaroxaban, dabigatran and vitamin K antagonists (VKAs) in patients with non-valvular atrial fibrillation(NVAF) (time frame: 23 months for the UK and Germany, 25 months for France). 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 NCT02488421, which also lists 2 linked publications.
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 20 Dec 2016; AzTrials last refreshed its copy on 8 Nov 2026.
