What this trial studies

This observational registry aims to collect data on patients with Antiphospholipid Syndrome (APS) who are treated with direct oral anticoagulants (DOACs) like Rivaroxaban. The study will ensure consistency in data collection and provide safety information for non-high-risk APS patients on these medications. Participants must be at least 18 years old and have been on DOACs for a minimum of six months. The registry will help in understanding the long-term effects and safety of DOACs in this patient population.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older diagnosed with definite APS who have been prescribed DOACs for at least six months.

Not a fit: Patients who do not meet the APS criteria or are under 18 years old will not benefit from this study.

Why it matters

Potential benefit: If successful, this registry could enhance the safety and efficacy of anticoagulant treatments for patients with Antiphospholipid Syndrome.

How similar studies have performed: While this registry approach is not widely tested, similar observational studies have successfully gathered valuable data on anticoagulant treatments in various populations.
