Primary Outcome Measures
NameTimeMethod
Number of Participants With at Least on Event of Venous Thromboembolism (VTE) and/or Death From Any Cause Recorded up to Day 47Baseline to Day 47

VTE was defined as a composite of symptomatic deep-vein thrombosis (DVT), symptomatic pulmonary embolism (PE), symptomatic extension of superficial vein thrombosis (SVT), or symptomatic recurrence of SVT. All VTEs were confirmed by objective tests and then adjudicated by an independent central adjudication committee (CAC), whose members were blinded to treatment assignment.

Secondary Outcome Measures
NameTimeMethod
Number of Participants With at Least One Event of Venous Thromboembolism (VTE) and/or Death From Any Cause Recorded up to Day 77Baseline to Day 77

VTE was defined as a composite of symptomatic deep-vein thrombosis (DVT), symptomatic pulmonary embolism (PE), symptomatic extension of superficial vein thrombosis (SVT), or symptomatic recurrence of SVT. All VTEs were confirmed by objective tests and then adjudicated by an independent central adjudication committee (CAC), whose members were blinded to treatment assignment.

Number of Adjudicated Major Bleeding Events and Deaths at Days 47 and 77Days 47 (or last dose plus 4 days) and 77

Major bleeding was defined as bleeding that was fatal and/or (1) in a critical area/organ (e.g., intracranial, intraspinal, intraocular, retroperitoneal, intra-articular or pericardial, or intramuscular with compartment syndrome); (2) associated with a fall in hemoglobin \>=20 g/L (1.24 mmol/L); (3) led to a transfusion of \>=2 units of packed red blood cells/whole blood. The revision of the Day 47 time point was to account for participants with treatment duration longer than 45 days. Adverse events were evaluated "On-Treatment," defined as from randomization up to the last injection +4 days.

Number of Participants Who Required Surgery to Treat Superficial Vein Thrombosis Recurrence at Days 47 and 77Days 47 and 77

The number of participants requiring surgery was measured.

Number of Adjudicated Non-Major Bleeding Events at Days 47 and 77Days 47 (or last dose plus 4 days) and 77

Clinically relevant non-major bleeding was defined as clinically relevant bleeding that did not qualify as major but satisfied a priori criteria, and/or any bleeding that resulted in clinical consequences for a participant. The revision of the Day 47 time point was to account for participants with treatment duration longer than 45 days. Adverse events were evaluated "On-Treatment," defined as from randomization up to the last injection +4 days.

Number of Any Adjudicated Bleeding Events at Days 47 and 77Days 47 (or last dose plus 4 days) and 77

The sum of adjudicated major bleeds, non-major clinically relevant bleeds, and minor bleeds was calculated. Minor bleeding was defined as other clinically overt bleeding events that did not meet the criteria for major or clinically relevant non-major bleeding. The revision of the Day 47 time point was to account for participants with treatment duration longer than 45 days. Adverse events were evaluated "On-Treatment," defined as from randomization up to the last injection +4 days.

Number of Participants With at Least One Occurrence of Each Adjudicated Component of the Primary Efficacy Endpoint at Days (D) 47 and 77Days 47 and 77

VTE was defined as a composite of symptomatic DVT; symptomatic PE; symptomatic extension of SVT, defined as downstream progression of the initial SVT by at least 2 cm and to within \<=3 cm from the sapheno-femoral junction; or symptomatic recurrence of SVT, defined as a new episode in any other superficial venous location, meeting the following criteria: the new SVT was in a different superficial vein and not directly contiguous upstream with the index SVT, or it was in the same superficial vein but clearly distinct from the index SVT with an open venous segment of at least 10 cm in length.
