Trial Outcomes & Findings for A Phase 2b Study of DU-176b, Prevention of Venous Thromboembolism in Patients After Total Knee Arthroplasty (NCT NCT01203072)

NCT ID: NCT01203072

Last Updated: 2019-02-25

Results Overview

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

PRIMARY outcome

Timeframe: 2 weeks

Population: The FAS was defined as all subjects enrolled in the study, but excluded those who had significant GCP violations, who had not received any doses of the study drug, or those who did not develop symptomatic DVT or PE, but in whom venography was not appropriately performed.

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
