Inclusion criteria

Inclusion criteria: Adult male or female subjects are eligible for study participation if they have confirmed (histology, adequate imaging modality) diagnosis of cancer (other than basal-cell or squamous cell carcinoma of the skin) and presentation with acute VTE, for which long-term treatment with DOACs is indicated. The key eligibility criteria include (all the following must be met at the screening and randomization visits): - Male or female subjects >= 18 years old or another legal maturity age according to the country of residence - Confirmed diagnosis of cancer (by histology or adequate imaging modality), other than basal-cell or squamous-cell carcinoma of the skin alone with one of the following: - Active cancer, defined as either locally active, regionally invasive, or metastatic cancer at the time of randomization, and/or - Currently receiving or having received anticancer therapy(radiotherapy, chemotherapy, hormonal therapy, any kind of targeted therapy or any other anticancer therapy) in the last 6 months. - Confirmed symptomatic or incidental proximal lower limb DVT (i.e.,popliteal, femoral, iliac, and/or inferior vena cava vein thrombosis) and/or a confirmed symptomatic PE, or an incidental PE in a segmental, or larger pulmonary artery. Patients are eligible within 120 hours from diagnosis of the qualifying VTE.

Exclusion criteria

Exclusion criteria: - Thrombectomy, insertion of a caval filter or use of a fibrinolytic agent to treat the current (index) occurrence of DVT and/or PE - More than 120 hours of pre-treatment with therapeutic doses of UFH, LMWH, fondaparinux, DOAC, or other anticoagulants - An indication to continue treatment with therapeutic doses of an anticoagulant other than that used for VTE treatment prior to randomization (e.g., atrial fibrillation, mechanical heart valve, prior VTE) - Platelet count 180 mm Hg or diastolic BP >100 mm Hg despite antihypertensive treatment)

Design outcomes

Primary

MeasureTime frame
Recurrent VTE is either: - Confirmed new symptomatic or incidental proximal DVT of the legs, iliac veins and/or inferior vena cava - Confirmed new symptomatic PE - Confirmed new incidental PE located in segmental or more proximal arteries. - Fatal PE (including unexplained death for which PE cannot be ruled out).
