Primary Outcome Measures:
  • Percentage of Subjects With Venous Thromboembolism Events [ Time Frame: 2 weeks ]

    The primary efficacy endpoint was the proportion of subjects who experienced at least one of the thromboembolic events listed below during the period from the start of study treatment to the venography at the end of study treatment.

    • Lower extremity DVT confirmed by bilateral venography at the end of study treatment
    • Definite diagnosis of symptomatic PE
    • Symptomatic DVT confirmed before the venography at the end of study treatment The objectives were to verify the non-inferiority of edoxaban to enoxaparin with regard to prevention of VTE


Secondary Outcome Measures:
  • Incidence of Major Bleeding or Clinically Relevant Non-major Bleedings. [ Time Frame: 2 weeks ]
