Rivaroxaban in Elderly Chinese Venous Thromboembolism Patients
China300 participantsStarted 2021-04-01
Plain-language summary
There's no unified recommendation in clinical practice regarding adjusting dosages for different patient types, especially when adverse events occur. While rivaroxaban typically doesn't require coagulation monitoring, in elderly patients, particularly those with multiple medications, finding appropriate lab indicators becomes crucial to gauge its anticoagulant effect. This aids in evaluating precise rivaroxaban dosing for the elderly, balancing bleeding risks and recurrence. Clinical pharmacological studies suggest that drug pharmacokinetics and pharmacodynamics in different populations can guide dosage optimization. Hence, this study aims to provide a basis for optimizing dosing regimens in high-risk elderly patients in China by exploring pharmacokinetic and pharmacodynamic indicators in clinical practice.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
* (1) Adult patients with objectively diagnosed acute symptomatic pulmonary embolism (with or without concurrent deep vein thrombosis) by imaging, who have completed acute anticoagulation and entered the anticoagulation maintenance phase; (2) Life expectancy greater than 3 months; (3) Meeting the indications for Xa factor inhibitor use; (4) Willingness to participate in this study, sign the informed consent form, and adhere to regular follow-ups.
Exclusion Criteria:
* (1) Moderate or severe hepatic impairment (Child-Pugh Class B or C); (2) Severe renal impairment (CrCl \< 15ml/min); (3) Pregnant or breastfeeding women; (4) Spontaneous bleeding tendencies, such as coagulation disorders or low platelet count (PLT \< 20×10\^9/L); (5) Contraindications to other Xa factor inhibitors' usage; (6) Patients diagnosed with hereditary thrombophilia and antiphospholipid syndrome.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
