• Target Recruitment: 1655

Inclusion Criteria

•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:
oActive cancer, defined as either locally active, regionally invasive, or metastatic cancer at the time of randomization, and/or
oCurrently 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 acute DVT (i.e., popliteal, femoral, iliac, and/or inferior vena cava vein thrombosis) and/or a confirmed symptomatic or incidental PE of a segmental, or larger pulmonary artery, and/or a confirmed symptomatic or incidental PE of two or more subsegmental pulmonary arteries.

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 72 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 <50,000/mm3
•PE leading to hemodynamic instability (systolic blood pressure [BP] <90 mmHg or shock)
•Acute ischemic or hemorrhagic stroke or intracranial hemorrhage within 4 weeks preceding screening
•Brain trauma, or a cerebral or a spinal cord surgery in the 4 weeks preceding screening
•Need for aspirin in a dosage of more than 100 mg/per day or any other antiplatelet agent alone or in combination with aspirin
•Primary brain cancer or untreated intracranial metastases at baseline
•Acute myeloid or lymphoid leukemia at baseline
•Bleeding requiring medical attention at the time of randomization or in the preceding 4 weeks
•Planned major surgery at baseline
•Eastern Cooperative Oncology Group (ECOG) performance status of 3 or 4 at screening
•Life expectancy <3 months at randomization
•Calculated creatinine clearance (CrCl) <30 mL/min (Cockcroft-Gault equation)
•Hemoglobin less than 8 g/dL
•Acute hepatitis, chronic active hepatitis, liver cirrhosis; or an alanine aminotransferase level 3 times or more and/or bilirubin level 2 times or more higher the upper limit of the normal range in absence of clinical explanation
•Uncontrolled hypertension (systolic BP>180 mm Hg or diastolic BP >100 mm Hg despite antihypertensive treatment)
•Women of child-bearing potential (WOCBP) who are unwilling or unable to use highly effective contraceptive measures during the study from screening up to 3 days after last treatment of dalteparin or 100 days after administration of abelacimab (See Section 5.3.6 for highly effective contraceptive measures).
•Sexually active males with sexual partners of childbearing potential must agree to use a condom or other reliable contraceptive measure up to 3 days after last treatment of dalteparin or 100 days after administration of abelacimab
•Pregnant or breast-feeding women
•Patients known to be receiving strong dual inducers or inhibitors of both CYP3A4 and P-gp
•History of hypersensitivity to any of the study drugs (including apixaban) or its excipients, to drugs of similar chemical classes, or any contraindication listed in the label for apixaban
•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
•Use of other investigational (not-registered) drugs within 5 half-lives prior to enrollment or until the expected pharmacodynamic effect has returned to baseline, whichever is longer. Participation in academic non-interventional or interventional studies, comprising testing different strategies or different combinations of registered drugs is permitted.
