This randomized phase III trial studies the side effects of and compares apixaban and dalteparin in reducing blood clots in patients with cancer-related venous thromboembolism. Venous thromboembolism is a condition in which a blood clot forms in a vein and then breaks off and moves through the bloodstream. Patients with cancer are at increased risk for venous thromboembolism. Apixaban and dalteparin are drugs used to prevent blood clots from forming or to treat blood clots that have formed. It is not yet known whether apixaban or dalteparin is more effective in reducing blood clots in patients with cancer related venous thromboembolism.
|Condition or disease||Intervention/treatment||Phase|
|Cerebral Vein Thrombosis Deep Vein Thrombosis Gonadal Thrombosis Hepatic Thrombosis Malignant Neoplasm Mesenteric Thrombosis Metastatic Malignant Neoplasm Portal Vein Thrombosis Pulmonary Embolism Renal Vein Thrombosis Splenic Thrombosis Venous Thromboembolism||Drug: Apixaban Drug: Dalteparin Other: Questionnaire Administration||Phase 3|
I. Any episode of major bleeding including fatal bleeding.
I. Venous thromboembolism (VTE) recurrence including deep vein thrombosis (DVT), pulmonary embolism (PE), fatal PE, or arterial thromboembolism.
II. Any episode of major bleeding including fatal bleeding or any episode of clinically relevant non-major bleeding.
OUTLINE: Patients are randomized to 1 of 2 treatment arms.
ARM I: Patients receive apixaban 10 mg orally (PO) twice daily (BID) on days 1-7 and lower-dose apixaban 5 mg PO BID on days 8-180.
ARM II: Patients receive dalteparin 200 international units (IU)/kg/day subcutaneously (SC) once daily (QD) on days 1-30 and lower-dose dalteparin 150 IU/kg/day SC QD on days 31-180.
After completion of study treatment, patients are followed up at 3 months.

|Actual Primary Completion Date :||April 2, 2018|
|Actual Study Completion Date :||December 24, 2019|
Experimental: Arm I (apixaban)
Patients receive apixaban 10 mg PO BID on days 1-7 and lower-dose apixaban 5 mg PO BID on days 8-180.
Other: Questionnaire Administration
Experimental: Arm II (dalteparin)
Patients receive dalteparin 200 IU/kg/day SC QD on days 1-30 and lower-dose dalteparin 150 IU/kg/day SC QD on days 31-180.
Other: Questionnaire Administration
- 6 Month Bleeding Rate [ Time Frame: Up to 6 months ]The rate (percentage) of patients experiencing major bleeding at 6 months from treatment initiation and its associated 95% confidence interval was estimated separately by treatment arm using a cumulative incidence function, treating death without bleeding as a competing risk.
- Composite Bleeding Rate: Major Bleed or a Clinically Relevant Non-major Bleed [ Time Frame: Up to 6 months ]A similar analysis as described for the primary safety analysis will be used. The rate (percentage) of patients experiencing major bleeding or a clinically relevant non-major bleed at 6 months from treatment initiation and its associated 95% confidence interval was estimated separately by treatment arm using a cumulative incidence function, treating death without bleeding as a competing risk.
- Time to the First Event of the Composite Deep Vein Thrombosis (DVT)/Pulmonary Embolism (PE) [ Time Frame: Up to 3 months post-treatment ]Analyzed using the same methods described above for the primary endpoint.Time to the first event of the composite deep vein thrombosis (DVT)/pulmonary embolism (PE) is defined as the time from randomization to the date the patient experienced the first event of the composite deep vein thrombosis (DVT)/pulmonary embolism (PE).

- Active cancer defined as metastatic disease and/or any evidence of cancer on cross-sectional or positron emission tomography (PET) imaging, cancer related surgery, chemotherapy or radiation therapy within the past 6 months; note: non-melanoma skin cancer does not meet the cancer requirement
- Life expectancy >= 60 days
- Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0, 1, or 2
- Obtained =< 30 days prior to randomization: Platelet count >= 50,000/mm^3
- Obtained =< 30 days prior to randomization: Alanine aminotransferase (ALT) or aspartate transaminase (AST) =< 3 x upper limit of normal (ULN)
- Obtained =< 30 days prior to randomization: International normalized ratio (INR) =< 1.6 (if not taking anticoagulant therapy)
- Obtained =< 30 days prior to randomization: Calculated creatinine clearance must be >= 30 ml/min using the Cockcroft-Gault formula
- Negative serum or urine pregnancy test done =< 24 hours prior to randomization, for women of childbearing potential only; note: a women of childbearing potential (WOCBP) is defined as any female who has experienced menarche and who has not undergone surgical sterilization (hysterectomy or bilateral oophorectomy) and is not postmenopausal; menopause is defined as 12 months of amenorrhea in a woman over age 45 years in the absence of other biological or physiological causes

- Note: women of child bearing potential must agree to follow instructions for method(s) of contraception for the duration of treatment with study drug (s) plus 33 days after finishing the last dose
- Males who are sexually active with WOCBP must agree to follow instructions for method(s) of contraception for the duration of treatment with study drug (s) plus 93 days after finishing the last dose
- Azoospermic males and WOCBP who are continuously not heterosexually active are exempt from contraceptive requirements; however they must still undergo pregnancy testing as described in this section
- Note: investigators shall counsel WOCBP and male subjects who are sexually active with WOCBP on the importance of pregnancy prevention and the implications of an unexpected pregnancy Investigators shall advise WOCBP and male subjects who are sexually active with WOCBP on the use of highly effective methods of contraception; highly effective methods of contraception have a failure rate of < 1% when used consistently and correctly
