| Measure | Time frame |
|---|---|
| Main Objective: The primary objective of the trial is to assess the safety and efficacy of odiparcil in the prevention of VTE following TKR and to provide evidence to enable the selection of a single dose of odiparcil for future investigation.; Secondary Objective: The secondary objective of this trial is to characterize the dose response, and PK/PD relationship of odiparcil. ; Primary end point(s): The primary endpoint of the trial is the incidence of total VTE (proximal and distal deep vein thrombosis (DVT), non-fatal pulmonary embolism (PE) and death due to VTE). This includes any asymptomatic DVT assessed by mandatory bilateral venography at the end of the study or at early withdrawal, symptomatic DVT confirmed by objective testing, or symptomatic PE confirmed by objective testing at any time during the study. Any deaths related to VTE that occur during the study or any subjects withdrawn from the Double-blind Treatment Period due to objectively confirmed symptomatic VTE will be included in the incidence. | — |
