What is being measured

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

  1. Combined endpoint

    All Stroke or Systemic embolism or Cardiovascular death

    Measured: 2 year

Secondary outcomes (4)
  1. All bleeding event

    Any bleeding with a need for hospitalization, instrumental procedure or discontinuation of anticoagulation or antithrombotic treatment.

    Measured: 2 year

  2. Major bleeding event

    An overt bleeding accompanied by one or more of the following: a decrease in hemoglobin level of 20 g/l or more over a 24-hour period, transfusion of 2 or more units of packed red cells, bleeding at a critical site (intracranial, intraspinal, intraocular, pericardial, intramuscular with compartment syndrome, or retroperitoneal), or fatal bleeding

    Measured: 2 year

  3. Technical and procedure related event

    A pericardial effusion with a need for drainage, surgical or pericardiocentesis, or cardioembolic event during the procedure, or significant periprocedural bleeding (i.e. major vascular bleeding with a need for surgical revision, or blood concentrate transfusion), or device embolization, or thrombus of the device with a consequent cardioembolic event.

    Measured: 45 days

  4. Cognitive function change

    Montreal Cognitive Assessment(MoCA) will be performed to detect cognitive function change.The differences between the MoCA test score in WATCHMAN group and in a control group of Rivaroxaban

    Measured: 2 year

Questions about this trial

What is this clinical trial studying?

A Phase 4 study testing WATCHMAN Left Atrial Appendage Occlusion Device and Rivaroxaban in people with Atrial Fibrillation and Stroke, run by Shulin Wu at 9 sites in China.

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 9 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: status not confirmed, as of the sponsor's last update on 24 Sep 2015. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 9 sites in China. 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?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Shulin Wu, M.D. Ph.D. (+8613902255336, doctorwushulin@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Combined endpoint (time frame: 2 year). 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 NCT02549963, which also lists 3 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 24 Sep 2015.
