Study Arms (3)

Warfarin

ACTIVE COMPARATOR

Subjects randomized to Warfarin will have warfarin administered daily in order to maintain a target INR of 2-3

Drug: Warfarin

Apixaban

ACTIVE COMPARATOR

Subjects randomized to Apixaban will have apixaban administered study drug of 2.5mg twice daily

Drug: Apixaban 2.5 MG

Rivaroxaban

ACTIVE COMPARATOR

Subjects randomized to Rivaroxaban will have rivaroxaban administered study drug of 10 mg daily

Drug: Rivaroxaban 10 MG

Interventions

Will be randomized to receive open label warfarin daily to achieve a target INR of 2-3

Warfarin

Will be randomized to receive open label apixaban of 2.5 mg twice daily

Apixaban

Will be randomized to receive open label rivaroxaban of 10mg daily

Rivaroxaban

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • To be eligible for this trial, patients must meet all of the following criteria:
  • Have confirmed acute, symptomatic, first lower extremity proximal DVT and/or PE that is NOT associated with a transient risk factor.
  • Have completed an initial treatment course of oral anticoagulant therapy for 3-12 months and have a recommendation from their provider to continue anticoagulation indefinitely.
  • Have the capacity to understand and sign an informed consent form.
  • Be 18 years of age and older.
  • Under the direct care of a healthcare provider for treatment of VTE for the length of time in the study.

You may not qualify if:

  • If a patient meets any of the following criteria, he or she may not be enrolled in the study:
  • Creatinine clearance (CrCl) \< 30 mL/min as determined by Cockcroft-Gault formula documented within 3 months from date of consent
  • Significant liver disease (Child-Pugh B or C)
  • Concomitant use of medications that are strong P-glycoprotein or CYP3A4 inducers/inhibitors
  • Another indication for chronic therapeutic-dose anticoagulation, such as atrial fibrillation (i.e., rivaroxaban, 10 mg daily, or apixaban, 2.5 mg twice daily, would not be appropriate therapy)
  • A clinical indication for a specific anticoagulant regimen (e.g., warfarin with a target INR of 2-3 is recommended for patients with 'triple-positive' antiphospholipid syndrome).
  • Life expectancy \< 3 months
  • Currently pregnant or breast feeding
  • Unable / unwilling to pay for one (or more) of the treatment options
  • Active Cancer defined as:
  • Diagnosed with cancer within the past 6 months; or Recurrent, regionally advanced or metastatic disease; Currently receiving treatment or have received any treatment for cancer during the 6 months prior to randomization; or A hematologic malignancy not in complete remission
  • Unwilling / unlikely to agree to follow up
