E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to compare the exposure (based on average concentration at steady state (Cav), minimum concentration in plasma (Cmin), and anti-factor Xa [anti-FXa]) of edoxaban 75 mg once daily (QD) dose to edoxaban 60 mg QD dose in NVAF anticoagulant-naïve patients with CHADS2 score of ≥ 2 and CrCL > 100 mL/min (as calculated by the Cockcroft-Gault formula) treated for up to 12 months. |
|
E.2.2 | Secondary objectives of the trial |
-Provide an assessment of exposure based on a validated anti-FXa assay using edoxaban calibrators and controls and edoxaban concentration based on liquid chromatography/tandem mass spectrometry;
-Provide an overall assessment of the patients’ coagulation state based on the PD biomarkers: intrinsic FX, prothrombin time (PT) and activated partial thromboplastin time ( aPTT);
-Investigate the relationship between exposure Proprietary and Confidential
4 (anti-FXa activity, edoxaban concentrations) and PD biomarkers (intrinsic FX, PT, aPTT).
-Evaluate stroke/transient ischemic attack (TIA) and systemic embolic events (SEE);
-Evaluate the net clinical outcome (composite of stroke/TIA, SEE, myocardial infarction (MI), cardiovascular death, major bleeding);
-Evaluate the incidence of major (including intracranial) and Clinically Relevant Non-Major [CRNM]) bleeding;
-Evaluate the incidence of stroke/ TIA and SEE excluding haemorrhagic stroke. |

(DOAC) for 30 days prior to randomization. |
|
E.4 | Principal exclusion criteria |
1. Patients with moderate or severe mitral stenosis, mitral valve rheumatic disease, unresected atrial myxoma, or a mechanical heart valve (patients with bioprosthetic heart valves and/or valve repair can be included) and/or other conditions, such as pulmonary embolism, considered to be a formal indication for conventional anticoagulation;
However patients with AF and valvular heart diseases such as mitral valve prolapse, mitral valve regurgitation, and aortic valve disease are allowed in the study as long as they are of non-rheumatic nature
2. Patients with acute myocardial infarction, acute coronary syndrome, or percutaneous coronary intervention within the previous 30 days, or ischemic stroke within the previous 7 days; subjects with ischemic stroke more than 7 days prior to randomization can be included provided there is no evidence of haemorrhagic transformation
3. Patients with any contraindication to anticoagulant agents;
4. Patients with conditions associated with high risk of bleeding such as a past history of intracranial (spontaneous or traumatic), spontaneous intraocular, spinal, retroperitoneal or intra-articular bleeding; overt gastrointestinal bleeding or active ulcer within the previous year; recent severe trauma, major surgery, or deep organ biopsy within the previous 10 days; active infective endocarditis; uncontrolled hypertension (blood pressure [BP] above 170/100 mmHg); or hemorrhagic disorder including known or suspected hereditary or acquired bleeding or coagulation disorder;
5. Patients anticipated to receive dual antiplatelet therapy (eg, aspirin plus thienopyridine such as clopidogrel, prasugrel, or ticagrelor) or aspirin alone at a dose > 100 mg daily during the study;
6. Patients receiving or anticipated to continue fibrinolytics and patients anticipated to continue with prohibited concomitant medications, such as
non-study anticoagulants, chronic oral or parenteral Non-Aspirin/Non-Steroidal Anti-Inflammatory Drugs (NSAID) for ≥ 4 days/week;
7. Patients that are either receiving or are planned to receive the following oral P-gp inhibitors concomitantly: ciclosporine, dronedarone, erythromycin, or ketoconazole (topical formulations of ketoconazole or erythromycin are allowed);
8. Patients with severe hepatic impairment or hepatic disease associated with coagulopathy (eg, acute hepatitis, chronic active hepatitis, cirrhosis);
9. Patients with known liver disease and with a combination of alanine aminotransferase (ALT)/ aspartate aminotransferase (AST) > 2 x upper limit of normal (ULN) and total bilirubin (TBL) > 1.5 x ULN;
10. Patients with hemoglobin < 10 g/dL or platelet count < 100,000 cells/mcL or white blood cell count < 3000 cells/mcL;
11. Patients with planned invasive procedures (other than routine endoscopy) or surgeries in which bleeding is anticipated during the study period;
12. Patients who received any investigational drug or device within 30 days prior to randomization, or plan to receive such investigational therapy during the study period;
13. Women of childbearing potential not using proper contraceptive measures, and women who are pregnant or breast feeding;
Note: Childbearing potential without proper contraceptive measures (ie, a method of contraception with a failure rate < 1 % during the course of the study (including the observational period). These methods of contraception according to the note for guidance on non-clinical safety studies for the conduct of human trials for pharmaceuticals (CPMP/ICH/286/95, modification) include consistent and correct use of hormone containing implants and injectables, combined oral contraceptives, hormone containing intrauterine devices, surgical sterilization, sexual abstinence, and vasectomy for the male partner);
14. Patients with the following diagnoses or situations:
Active cancer undergoing chemotherapy, radiation or major surgery within the next 3 months;
Significant active concurrent medical illness or infection;
Life expectancy < 12 months.
15. Patients who are unlikely to comply with the protocol (eg, unable to swallow tablets whole uncooperative attitude, inability to return for subsequent visits, and/or otherwise considered by the Investigator to be unlikely to complete the study);
16. Patients with a known drug or alcohol dependence within the past 12 months as judged by the Investigator;
17. Patients with any condition that, in the opinion of the Investigator, would place the patient at increased risk of harm if he/she participated in the study. |
