Study Endpoints
Primary Endpoints
Number of Participants With Major Bleeding Events [Per International Society on Thrombosis and Homeostasis (ISTH) Definition] or Clinically Relevant Non-major (CRNM) Bleeding Events Adjudicated by Clinical Event Committee During the Treatment Period
Baseline to Week 24

Major bleeding event was defined as an acute clinically overt bleeding accompanied by a decrease in hemoglobin of 2 g/dL or more, a transfusion of 4 or more units of packed red blood cells (a unit of packed red blood cells equal to about 200 cc), or bleeding that occurred in critical sites (e.g. intracranial). Fatal bleeding was also defined as a major bleeding event. CRNM bleeding event was defined as an acute clinically overt bleeding that did not satisfy the definition of major bleeding and that led to either hospitalization, physician guided medical or surgical treatment for bleeding, or a change in antithrombotic therapy.

Secondary Endpoints
Number of Participants With Adjudicated Recurrent Symptomatic Venous Thromboembolism (VTE) [Nonfatal Deep Venous Thrombosis (DVT) or Nonfatal Pulmonary Embolism (PE)] or VTE-Related Death During the Intended Treatment Period
Baseline to Week 24
Number of Participants With Adjudicated Thrombotic Burden Worsened in Acute Symptomatic Proximal Deep Venous Thrombosis (DVT)
Baseline to Week 24
Number of Participants With Adjudicated Thrombotic Burden Worsened in Acute Symptomatic Pulmonary Embolism (PE)
