A Randomized, Open-Label, Parallel-Group, Multi-Center Study for the Evaluation of Efficacy and Safety of Edoxaban Monotherapy Versus Low Molecular Weight (LMW) Heparin/Warfarin in Subjects With Symptomatic Deep-Vein Thrombosis (eTRIS)

This is an interventional treatment trial for Deep Vein Thrombosis Read More

Inclusion Criteria:

• Male or female subjects older than the minimum legal adult age (country specific)
• Acute symptomatic proximal DVT involving the popliteal, femoral or iliac veins confirmed by compression ultrasonography (CUS) or other appropriate imaging techniques (such as venography or spiral/contrast CT) with symptom onset < or = 1week prior to randomization
• Able to provide signed informed consent

Exclusion Criteria:

• Concomitant pulmonary embolism known to the investigator at the time of randomization
• Thrombectomy, insertion of a caval filter, or use of a fibrinolytic agent to treat the current episode of DVT
• Indication for warfarin other than DVT
• More than 48 hours pre-treatment with therapeutic dosages of anti-coagulant treatment [low molecular weight heparin (LMWH), unfractionated heparin (UFH), fondaparinux, VKA, factor Xa inhibitor or other anti coagulant per local labeling] prior to randomization to treat the current episode
• Treatment with any investigational drug within 30 days prior to randomization
• Calculated creatinine clearance (CrCL) < 30 mL/min
• Significant liver disease (e.g., acute hepatitis, chronic active hepatitis, cirrhosis) or alanine aminotransferase (ALT) > or = 2 times the upper limit of normal (ULN), or total bilirubin (TBL) > or = to 1.5 times the ULN (however subjects whose elevated TBL is due to known Gilbert's syndrome may be included in the study)
• Subjects with active cancer for whom long term treatment with (LMW) heparin is anticipated
• Life expectancy < 3 months
• Active bleeding or high risk for bleeding contraindicating treatment with (LMW) heparin or warfarin
• Uncontrolled hypertension as judged by the Investigator (e.g., systolic blood pressure > 170 mmHg or diastolic blood pressure > 100 mmHg despite antihypertensive medications confirmed by repeat measurement)
• Women of childbearing potential without proper contraceptive measures (i.e., a method of contraception with a failure rate < 1 % during the course of the study including the observational period) and women who are pregnant or breast feeding
• Any contraindication listed in the local labeling of LMWH, UFH, or warfarin
• Chronic treatment with non-aspirin non-steroidal anti-inflammatory drugs (NSAIDs) including both cyclooxygenase-1 (COX-1) and cyclooxygenase-2 (COX- 2) inhibitors for > or = 4 days/week anticipated to continue during the study.
• Treatment with aspirin in a dosage of more than 100 mg/per day or dual antiplatelet therapy (any two antiplatelet agents including aspirin plus any other oral or intravenous [IV] antiplatelet drug) anticipated to continue during the study
• Treatment with P-gp inhibitors is not permitted at the time of randomization; subsequent use is permitted, with a dose reduction in the edoxaban monotherapy treatment arm.
• Known history of positive Hepatitis B antigen or Hepatitis C antibody
• Subjects with any condition that, as judged by the investigator, would put the subject at increased risk of harm if he/she participated in the study; including, but not limited to, subjects at increased risk of harm if given a gadolinium-based contrast agent such as gadofosveset trisodium (Ablavar®)
• Subjects for whom MRI would be contraindicated (e.g., subjects with metal implants) or for whom the use of a gadolinium-based contrast agent such as gadofosveset trisodium (Ablavar®) would be contraindicated
• Subject has previously entered this study or another edoxaban study
