Atrial FibrillationNCT05532878
Pharmacokinetics of Apixaban in Peritoneal Dialysis
An observational study of Atrial Fibrillation, run by Chinese University of Hong Kong at 1 site in Hong Kong.
Trial summary
Atrial fibrillation (AF) is fairly prevalent in patients with end stage renal disease (ESRD) with the prevalence estimated to be 3.8 - 27%. While it is reported that patient with peritoneal dialysis (PD) has a lower incidence of AF as compared to patient with haemodialysis (HD), the risk is still substantially higher… Read more about this study

About this study
Official title: Pharmacokinetics and Safety Profile of Apixaban in Patients With Peritoneal Dialysis
Atrial fibrillation (AF) is fairly prevalent in patients with end stage renal disease (ESRD) with the prevalence estimated to be 3.8 - 27%. While it is reported that patient with peritoneal dialysis (PD) has a lower incidence of AF as compared to patient with haemodialysis (HD), the risk is still substantially higher than in the general population. AF is a known risk factor for embolic stroke and stroke causes significant morbidity and mortality. Anticoagulation in an effective treatment for the prevention of stroke in the general population. However, this is less clear in the ESRD populations.
Despite the risk of stroke is higher than general population, the management of AF in patients with ESRD remains controversial with limited and often conflicting result for the use of traditional vitamin K antagonists. It also showed an increased risk of bleeding with the use in ESRD patients.

With the advent of direct oral anticoagulants (DOACs), there is growing interest in advocating their uses and studies have been done to assess their safety profile. In fact, several randomized control trials are being performed. However, these studies are done in HD populations and there is no data for PD populations at all so far.
Given the physiology of drug clearance is different between the two renal replacement modalities, the investigators purpose to assess the pharmacokinetics and the safety profile of Apixaban in PD populations. By establishing the pharmacokinetics and its safety profile, apixaban may be a more attractive option for anticoagulation for AF or other venous thrombotic indications in PD population.

The record lists 1 site in Hong Kong. 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.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Apixabn level (time frame: 0 to 12 hours (14 time points)). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
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 21 Oct 2026.
