|Official Title:||A Phase 3, Randomized, Double-Blind, Double-Dummy Efficacy and Safety Study of the Oral Factor Xa Inhibitor DU-176b Compared With Enoxaparin Sodium for Prevention of Venous Thromboembolism in Patients After Total Knee Arthroplasty (STARS E-3 Trial)|
- Incidence of Subjects With Venous Thromboembolism Events. [ Time Frame: 2 weeks ] [ Designated as safety issue: No ]
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 Deep Vein Thrombosis (DVT) confirmed by unilateral venography at the end of study treatment
- Definite diagnosis of symptomatic Pulmonary Embolism (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 venous Thromboembolism (VTE)
- Incidence of Major Bleeding or Clinically Relevant Non-major Bleeding. [ Time Frame: 2 weeks ] [ Designated as safety issue: Yes ]
