An Observational Study (Called RETAF-PS) Using a Patient Survey to Learn More About Treatment Outcomes in Patients With Irregular and Often Rapid Heartbeat (Atrial Fibrillation) Treated With Apixaban in a Real World Setting
REal-World Treatment Outcomes of Oral-Anticoagulants Among Patients With Atrial Fibrillation - Patient Survey - RETAF-PS
This is an observational study in which data from people with atrial fibrillation who received or are currently receiving the drug apixaban to prevent thromboembolic events (blood clots that travel through the blood stream to plug another smaller vessel) are studied. In observational studies, only observations are made without specified advice or interventions.
Atrial Fibrillation (AF) is a condition of having irregular and often rapid heartbeat. AF can lead to the formation of blood clots in the heart and to embolism, a condition that happens when a blood clot travels through the blood stream to plug another smaller vessel. This can lead to serious and life-threatening conditions, such as a stroke. A stroke occurs because the brain tissue beyond the blockage no longer receives nutrients and oxygen so that brain cells die. As strokes arising from AF can involve extensive areas of the brain, it is important to prevent them.
Blood clots are formed in a process known as coagulation. This is a complex series of steps that must occur in a specific sequence.
Medications are already available to prevent the formation of blood clots. When taken by mouth (orally), they are known as oral anticoagulants (OACs). OACs decrease the risk of the above-mentioned serious and life-threatening conditions. The main side effect of OACs is an increase of the risk of bleeding.
In the beginning, there was only one main class of OAC called vitamin k antagonists (VKAs) prescribed in usual practice. VKAs work by lowering the number of coagulation factors in the blood. Over the years, newer OAC medications have become available which act more specifically by interrupting one or more of the coagulation steps and preventing the blood from clotting. The study treatment apixaban works by blocking a very specific step in the blood clotting process, the activation of a protein called Factor Xa. Newer OACs are also called direct oral anticoagulants (DOACs). DOACs require less monitoring by doctors, but an increased risk of bleeding remains.
Bleedings can be an important reason for stopping therapy. One type of bleeding called patient relevant bleeding (PRB) has not been intensely studied so far. PRB is a type of minor bleeding which is bothersome, but which does not require medical treatment as it has no important impact on a person's health.
It needs to be distinguished from so called clinically relevant non-major bleeding (CRNMB). CRNMB stands for a type of bleeding which may have an important impact on a person's health and needs medical attention, but when treated, is not likely to have a negative impact on a person's health.
Only limited information is available for PRB and CRNMB related to the treatment with DOACs in real-world settings.
In this study, researchers want to collect more data about how often PRB and CRNMB occur in people with AF treated with apixaban. In addition, researchers want to learn how these medical problems affect the treatment with apixaban under real-world conditions. To do this, researchers will count the number of participants in usual practice
- who have PRB or CRNMB and who are being treated with apixaban at the time of this ongoing study or who have recently taken this drug, but have switched to another OAC,
- who have PRB or CRNMB and have decided to stop or to continue their treatment with apixaban.
In addition, characteristics of each participant and the reason for continuation or discontinuation of apixaban will be collected and described. The data for this study will come from patient surveys.
Besides this data collection, no further tests or examinations are planned in this study.
The participants who take their apixaban treatment during this study will receive their treatments as prescribed by their doctors during routine practice according to the approved product information.
The data will be from participants who will be identified for the survey using last 12-months data from the database called HealthCore Integrated Research Database (HIRD). The data will be collected for each participant for 12 months before the participant starts the survey. The study will end as soon as the planned number of surveys has been reached or at the end date of the study.
