Study summary

This non-interventional field study will investigate rivaroxaban under clinical practice conditions for stroke prevention and for prevention of non-CNS systemic embolism in patients with non-valvular atrial fibrillation in China.

Read the detailed description

3000 patients will be provided with free drug.It is planned to have an interim analysis(IA) when 3000 patients are enrolled (cut off day is the 3000th patient completed at least 3 months follow-up visit). To end or continue enrolling patients will be decided based on the IA result and the evaluation comments from CFDA.

What researchers measure

Primary outcomes

  1. Number of Major bleeding events

    Major bleeding events, collected as serious or non serious adverse events and defined as overt bleeding associated with: 1. a fall in haemoglobin of ≥2 g/dL, or 2. a transfusion of ≥2 units of packed red blood cells or whole blood, or 3. occurrence at a critical site (intracranial, intra-spinal, intraocular, pericardial, intra articular, intra-muscular with compartment syndrome, retroperitoneal), or 4. death

    Time frame: Up to 30 months

Secondary outcomes

  1. Number of Symptomatic thromboembolic events

    Collected as serious or non-serious adverse events

    Time frame: Up to 30 months

  2. Number of Non-major bleeding

    Collected as serious or non-serious adverse events and defined as all bleeding events that do not fall in the category of major bleedings

    Time frame: Up to 30 months

  3. Treatment satisfaction questionnaire

    Time frame: Up to 30 months

  4. Adverse event and serious adverse event percentage in the different atrial fibrillation risk factor categories

    Time frame: Up to 30 months

  5. Number of each reason for any switch from or interruption of rivaroxaban treatment

    If the patients switch from or interruption of rivaroxaban treatment, patients or physicians will be asked by several questions about the reasons of the switch and interruption, and collected in CRF. The reasons will be described by frequency distributions. Reason choice as below: 1. Patient choice 2. Insufficient therapeutic effect 3. Adverse event 4. Surgery 5. Dentistry 6. Renal function change

    Time frame: Up to 30 months
