Population Pharmacokinetics of Edoxaban in Chinese Patients With Non-Valvular Atrial Fibrillation
- Registration Number
- NCT05320627
- Lead Sponsor
- China National Center for Cardiovascular Diseases
- Brief Summary
Based on the population pharmacokinetic data of Chinese patients with atrial fibrillation, the study will evaluate the suitability of the ENGAGE Population Pharmacokinetics model of edoxaban in patients with atrial fibrillation in China, and build a predictive dose model of edoxaban that meets the characteristics of Chinese people. It can provide perfect individualized dosing plan improves clinical efficacy and reduces adverse drug reactions.
- Detailed Description
This is an open label study. Male or female patients with non-valvular atrial fibrillation (NVAF) with age ≥20 years, and meeting the indications of edoxaban are potentially eligible for the study. Patients receive Edoxaban 15mg、30mg or 60mg according to the criteria as following:
1. Patients with severe renal insufficiency (15ml/min ≤ CrCl \<30ml/min), 15mg quaque die (QD)
2. Patients with normal or mild renal insufficiency (CrCl ≥50ml/min), 60mg QD
3. Patients with moderate renal insufficiency (30ml/min ≤ CrCl \<50ml/min), weight ≤60kg or combined use of P-gp inhibitors (such as dronedarone，ketoconazole, erythromycin, etc), 30mg QD.
Patients will receive clinical evaluation at screening period, 4 weeks、8 weeks and 12 weeks after administration with Edoxaban. The following clinical evaluation items were included: body weight, vital signs (blood pressure and heart rate), CHADS2-VAS score, concomitant medication, ECG and echocardiogram, laboratory examination, safety evaluation (thromboembolic events, bleeding events, death) during treatment.
Additional blood samples are collected for pharmacokinetic evaluation at screening period, pre-dose, 2±1h and 6±1h after administration at 4-, 8-, and 12-week visit, and for pharmacodynamic evaluation (FXa) at screening period, pre-dose after administration at 4-, 8-, 12-week visit.
The population pharmacokinetics of Edoxaban in Chinese patients with non-valvular atrial fibrillation will be determined after 12weeks clinical observation.
The ENGAGE PopPK model suitable in Chinese Patients with Non-Valvular Atrial Fibrillation will be established.
Safety outcomes (thromboembolic events, bleeding events, death) will be evaluated.

- Primary Outcome Measures
Name Time Method population pharmacokinetic evaluation at the 4th, 8th and 12th week Patients enrolled will be back to center for visit at scheduled timepoint. Blood sample for PopPK study was collected. Edoxaban concentrations in patient plasma will be determined, which will be analysed and compared with ENGAGE PopPK model.
pharmacokinetic evaluation at the 4th, 8th and 12th week Patients enrolled will be back to center for visit at scheduled timepoint. Blood for pharmacodynamic sample will be collected for Anti-FXa activity determination.
- Secondary Outcome Measures
Name Time Method safety evaluation at the 4th, 8th and 12th week Patients enrolled will be back to center for visit at scheduled timepoint. Adverse even will be recorded. The investigator will determine whether the patient is suitable to go on with the study.
