About this study

Official title: An Observational Post-Authorization Safety Specialist Cohort Event Monitoring Study (SCEM) to Monitor the Safety and Utilization of Rivaroxaban (Xarelto®) for the Prevention of Stroke in Patients With Atrial Fibrillation (AF), Treatment of Deep Vein Thrombosis (DVT) and Pulmonary Embolism (PE), and the Prevention of Recurrent DVT and PE in the Secondary Care Hospital Setting in England and Wales.

This study aims to evaluate the use of rivaroxaban and its short term safety when used by patients for the new indications of prevention of stroke and systemic embolism in patients with non-valvular atrial fibrillation, treatment of deep vein thrombosis (DVT) and pulmonary embolism (PE) and prevention of recurrent DVT and PE. Any adult patient started by their care team on rivaroxaban or an alternative anticoagulant for the specified indications during the study period will be eligible to take part. A questionnaire will be completed by the care team of each patient at the start of treatment and again 12 weeks later. The care team will complete the questionnaires using information from the patient's medical notes, not by asking the patient directly. If a participant has an adverse event during the 12 week period, we may ask the patient's care team to fill out a further follow up questionnaire. No other examinations or tests will be performed. Patients will only be recruited to the study after the clinical decision to prescribe rivaroxaban or an alternative anticoagulant has been made, so that prescribing behaviour is not altered by the study. It is an observational, non-interventional study covering the whole of England and Wales.

What is being measured

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

  1. Cumulative incident risk of haemorrhage within gastrointestinal and urogenital organ sites (which meets the criteria for a major bleed) and all intracranial sites.

    The cumulative incidence will be calculated according to the formula:

    Total number of new cases during 12 week observation period x 100 / Population initially at risk

    If the observed cumulative incidence from this study falls within the range expected as set by the precision limits of cumulative incidence from clinical trial data, then the null hypothesis (of no difference) will not be rejected.

    Measured: During 12 weeks after initiation of treatment with rivaroxaban or alternative anticoagulant therapy

Questions about this trial

What is this clinical trial studying?

An observational study of Atrial Fibrillation and Deep Vein Thrombosis, run by Professor Saad Shakir at 1 site in United Kingdom.

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 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 30 Jan 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 United Kingdom. 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?

Cumulative incident risk of haemorrhage within gastrointestinal and urogenital organ sites (which meets the criteria for a major bleed) and all intracranial sites. (time frame: During 12 weeks after initiation of treatment with rivaroxaban or alternative anticoagulant therapy). 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 NCT01871194, 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 30 Jan 2018.
