Oral Apixaban (Eliquis) Versus Enoxaparin (Lovenox) for Thromboprophylaxis in Women With Suspected Pelvic Malignancy

Completed · Phase 2

Conditions studied: Gynecologic Cancer, Venous Thromboembolism

In brief

The study will evaluate the incidence of major bleeding (including clinically relevant non-major (CRNM) bleeding) events in women undergoing surgery for gynecologic cancer with apixaban 2.5 mg twice a day (BID) compared to current standard of care, subcutaneous enoxaparin 40 mg once a day (QD) for 28 days post surgery.

You may qualify if…

• Suitable candidate for surgery (meets appropriate performance status, no significant cardiac/renal/hepatic dysfunction
• Diagnosis of pelvic malignancy (suspected/confirmed ovarian, endometrial/uterine, cervical cancers, and vulvar cancers) undergoing surgical debulking,
• Women of childbearing potential (WOCBP) must have a negative serum or urine pregnancy test (minimum sensitivity 25 IU/L or equivalent units of HCG) within 24 hours prior to surgery,
• Women must not be breastfeeding, WOCBP must agree to follow instructions for method(s) of contraception for the duration of treatment with study drug(s) apixaban plus 5 half-lives of study drug apixaban (2.5 days) plus 30 days (duration of ovulatory cycle) for a total of 32.5 days post-treatment completion.

You may not qualify if…

• Malignancy or mass that is non-gynecologic in origin (mass/tumor of origin other than reproductive organ such as rectal, abdominal, breast)
• Positive pregnancy test on day of surgery,
• Known history of Venous (Thromboembolism) VTE prior to diagnosis (DVT or Pulmonary Embolism (PE)) due to increased underlying risk of new event
• Concomitant NSAIDS or other anticoagulant/antiplatelet therapy including Acetylsalicylic Acid (Aspirin) (ASA) >81mg/day,
• Selective serotonin re uptake inhibitor (SSRIs) and Serotonin-nor-epinephrine re uptake inhibitor (SNRIs) (common anti-depressant therapies),
• Uncontrolled severe hypertension (systolic >200 mmHg or diastolic >120 mmHg),
• With prosthetic heart valves,
• Active bleeding condition (not limited to: thrombocytopenia, haemophilias, potential bleeding lesions, recent trauma or surgery, recent stroke, confirmed intracranial or intraspinal bleeding),
• Known or documented bleeding disorders not limited to: anti-phospholipid syndrome, homozygotes for Factor V Leiden deficiency, antithrombin III deficiency, protein C deficiency, Protein S deficiency, hyperhomocysteinemia, systemic lupus erythematous, or Prothrombin G2020 gene mutation,
• Significant renal disease as defined by creatinine clearance less than 30 mL/min,
• Significant liver disease as defined as Aspartate Transaminase (AST) or Alanine Transaminase (ALT) twice than normal,
• Concomitant use of dual strong inhibitors or inducers (CYP3A4, P-gp)
• Protein C deficiency (increased risk of skin necrosis do those on injectable anticoagulation),
• Documented allergy to apixaban and/or enoxaparin,
• Patient's deemed otherwise clinically unfit for clinical trial per Investigator's discretion
