Dose-confirmatory Bridging Study in Total Knee Replacement

• Status: Completed
• Trial end date: 2011-06-01
• Target enrollment: 0
• Participant gender: All

Summary

The objective of this dose-confirmatory bridging study is to investigate the safety and efficacy of rivaroxaban 5 to 10 mg once-daily (od) dosing in the prevention of venous thromboembolism (VTE) in Japanese patients undergoing elective total knee replacement (TKR) and to confirm the extrapolability of global data to Japanese patients by comparing with data from overseas phase III study (RECORD 3 - Study 11356) and phase II studies.

• History of clinically significant active bleeding (e.g. intracranial bleeding, gastrointestinal bleeding*), or high bleeding risk

*: within 3 months prior to elective TKR for gastrointestinal bleeding

• Subjects with hepatic disease which is associated with coagulopathy leading to a clinically relevant bleeding risk

• Conditions prohibiting bilateral venography (e.g. amputation of 1 leg, allergy to contrast media)

• Ongoing anticoagulant therapy (e.g. warfarin, heparins and Factor Xa inhibitors other than study medication) that cannot be stopped (in the opinion of the investigator/sub investigator)
