A Phase III, Randomized, Controlled, Double-Blind Study Evaluating the Safety of Two Doses of Apixaban for Secondary Prevention of Cancer Related Venous Thrombosis in Subjects Who Have Completed at Least Six Months of Anticoagulation Therapy

This randomized phase III trial studies the best dose of apixaban and how well it works in
preventing secondary cancer related blood clots in cancer patients who have completed
anticoagulation therapy. Apixaban may stop the clotting of blood by blocking some of the
enzymes needed for blood clotting.

PRIMARY OBJECTIVES:

I. Any episode of major bleeding including fatal bleeding or clinically relevant non-major
bleeding.

SECONDARY OBJECTIVES:

I. The proportion of patients who experienced at least one such bleeding event within 6
months of beginning treatment.

II. Venous thromboembolism (VTE) recurrence including deep vein thrombosis (DVT), pulmonary
embolism (PE), fatal PE, or arterial thromboembolism.

OUTLINE: Patients are randomized to 1 of 2 groups.

GROUP I: Patients receive lower dose apixaban orally (PO) twice daily (BID) for 365 days.

GROUP II: Patients receive higher dose apixaban PO BID for 365 days.

After completion of study treatment, patients are followed up for 12 months.

Inclusion Criteria:

- Confirmed acute index (original venous thrombotic) event: lower extremity or upper
extremity (jugular, innominate, subclavian, axillary, brachial) DVT, PE, splanchnic
(hepatic, portal, splenic, mesenteric, renal, gonadal), or cerebral vein thrombosis
for which the patient has received >= 180 days (but =< 365 days) of anticoagulant
therapy prior to registration; the date, imaging modality, and location of index event
will be required; the date of initiation and specific type of anticoagulants used will
also be required

- 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 >= 6 months

- Eastern Cooperative Oncology Group (ECOG) performance status (PS) of 0, 1, or 2

- Hemoglobin >= 8 g/dL obtained =< 30 days prior to registration

- Platelet count >= 50,000/mm^3 obtained =< 30 days prior to registration

- Alanine aminotransferase (ALT) or aspartate transaminase (AST) =< 3 x upper limit of
normal (ULN) obtained =< 30 days prior to registration

- Calculated creatinine clearance must be >= 30 ml/min using the Cockcroft-Gault formula
obtained =< 30 days prior to registration

- Negative serum or urine pregnancy test done =< 7 days prior to registration, for women
of childbearing potential only;

- Note: a woman 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

- Ability to provide informed written consent

- Willing to undergo monthly follow-up assessment, either in person at the enrolling
institution or by telephone

Exclusion Criteria:

- Any of the following:

- Pregnant women

- Nursing women

- Men or women of childbearing potential who are unwilling to employ adequate
contraception

- 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; at a minimum, subjects must agree to the use of one method of
highly effective contraception as listed below:

- Male condoms with spermicide

- Hormonal methods of contraception including combined oral contraceptive
pills, vaginal ring, injectables, implants and intrauterine devices
(IUDs) such as Mirena by WOCBP subject or male subject?s WOCBP partner

- Female partners of male subjects participating in the study may use
hormone based contraceptives as one of the acceptable methods of
contraception

- IUDs, such as ParaGard

- Tubal ligation

- Vasectomy

- Complete abstinence

- Complete abstinence is defined as complete avoidance of
heterosexual intercourse and is an acceptable form of
contraception for all study drugs; acceptable alternate methods of
highly effective contraception must be discussed in the event that
the subject chooses to forego complete abstinence

- Active major bleeding

- Severe hypersensitivity reaction to apixaban (e.g., anaphylactic reactions)

- Current use of strong CYP3A4 inducers or inhibitors

- NOTE: patients may be eligible if they transition to an alternative agent or are
able to stop CYP3A4 inducer or inhibitor

- Current use of thienopyridine therapy (clopidogrel, prasugrel, or ticagrelor) that
will be continued on study

- Severe liver disease (known cirrhosis Childs Pugh class B or C), or active hepatitis

- Documented venous thromboembolism while on therapeutic anticoagulation
(?anticoagulation failure?)

- Mechanical heart valve

- Documented hemorrhagic tendencies (e.g., hemophilia)

- Bacterial endocarditis

- Any of the following conditions:

- Intracranial bleeding =< 6 months prior to randomization

- Intraocular bleeding =< 6 months prior to randomization

- Gastrointestinal bleeding and/or endoscopically proven ulcer =< 6 months prior to
randomization

- Head trauma or major trauma =< 1 month prior to randomization

- Neurosurgery =< 2 weeks prior to randomization

- Major surgery =< 1 week prior to randomization

- Gross hematuria at the time of randomization
