E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary objective is to demonstrate the non-inferiority of edoxaban
(preceded by a short course a LMWH compared with dalteparin for the
prevention of the combined outcome of recurrent venous
thromboembolism (VTE) or major bleeding in subjects with VTE
associated with cancer during a 12-month study period. If noninferiority
is established, LMWH/edoxaban will be compared with
dalteparin for superiority.
|
|
E.2.2 | Secondary objectives of the trial |
To compare LMWH/edoxaban with dalteparin with regards to rates of:
1. Recurrent VTE;
2. Major bleeding;
3. Clinically relevant non-major (CRNM) bleeding;
4. Major + CRNM bleeding;
5. All bleedings
6. Event-free survival, defined as the proportion of subjects over time
free of recurrent VTE, major bleeding events, and death;
7. VTE-related death;
8. Mortality from all causes;
9. Recurrent deep vein thrombosis (DVT);
10. Recurrent pulmonary embolism (PE);
11. Healthcare resource utilization for potential recurrent VTE and bleed
events. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Adult subjects presenting with VTE associated with cancer (other than basal-cell or squamous-cell carcinoma of the skin) for whom long-term treatment with LMWH is intended are eligible to participate in the study.
Subjects must satisfy all of the following criteria to be included in the study:
1. Male or female subjects with age ≥ 18 years or the otherwise legal lower age according to the country of residence;
2. Confirmed symptomatic or unsuspected lower extremity proximal DVT (ie, popliteal, femoral, iliac or inferior vena cava (IVC) vein thrombosis), or confirmed symptomatic PE, or unsuspected PE of a segmental or larger pulmonary artery;
3. Cancer (other than basal-cell or squamous-cell carcinoma of the skin), either active or diagnosed within 2 years prior to randomization. [Note: Diagnosis of cancer must be objectively documented];
4. Intention for long-term treatment (at least 6 months) with parenteral LMWH;
5. Able to provide written informed consent.
|
|
E.4 | Principal exclusion criteria |
1. Thrombectomy, insertion of a caval filter, or use of a fibrinolytic agent
to treat the current (index) episode of DVT and/or PE;
2. More than 72 hours pre-treatment with therapeutic dosages of
anticoagulant treatment (LMWH, unfractionated heparin, and
fondaparinux per local labeling), oral direct anticoagulants or VKA prior
to randomization to treat the current (index) episode;
3. Treatment with therapeutic doses of an anticoagulant including
dalteparin for an indication other than VTE prior to randomization;
4. Active bleeding or any contraindication for treatment with
LMWH/dalteparin or edoxaban;
5. An Eastern Cooperative Oncology Group (ECOG) Performance Status of
3 or 4 at the time of randomization (Appendix 17.6);
6. Calculated CrCL < 30 mL/min;
7. History of heparin associated thrombocytopenia;

ULN) and bilirubin (> 2 x ULN) elevations in the absence of a clinical
explanation;
10. Life expectancy < 3 months;
11. Platelet count < 50,000/mL;
12. Uncontrolled hypertension as judged by the Investigator (eg, systolic
blood pressure (BP) > 170 mmHg or diastolic blood pressure > 100
mmHg despite antihypertensive treatment);
13. Women of childbearing potential without 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 nonclinical 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. Chronic treatment with non-aspirin non-steroidal anti-inflammatory
drugs (NSAIDs) including both cyclooxygenase-1 (COX-1) and
cyclooxygenase-2
(COX-2) inhibitors for ≥ 4 days/week anticipated to continue during the
study;
15. Treatment with aspirin in a dosage of more than 100 mg/per day or
dual antiplatelet therapy (any 2 antiplatelet agents including aspirin plus
any other oral or intravenous [IV] antiplatelet drug) anticipated to
continue during the study;
16. Treatment with the P-gp inhibitors ritonavir, nelfinavir, indinavir, or
saquinavir anticipated to continue during the study;
17. Systemic use of the P-gp inhibitors ketoconazole, itraconazole,
erythromycin, azithromycin or clarithromycin at the time of
randomization; subsequent use is permitted (with appropriate dose
reduction of edoxaban);
18. Subjects with any condition that as judged by the Investigator would
place the subject at increased risk of harm if he/she participated in the
study. |

E.5 End points |
E.5.1 | Primary end point(s) |
The primary study outcome is the composite of recurrent
VTE, and major bleeding.
Recurrent VTE is either:
-symptomatic confirmed (new) DVT or (new) PE;
-unsuspected (new) proximal DVT of the legs or unsuspected (new) PE located in segmental or more proximal arteries:
Unsuspected DVT or PE are thrombi that are detected during imaging testing performed for other reasons (eg, computed tomography (CT) for cancer staging) and not for suspicion of DVT or PE.
-fatal PE (including unexplained death for which PE cannot be ruled out).

Definition of the end of the trial and justification where it is not the last

Once 1000 subjects are randomized, a global End-of-Treatment (EOT) date will be established that ensures a minimum of 6 months of study treatment and follow-up for the final subject(s) randomized. All subjects will permanently discontinue study treatment on or before the EOT date. |
