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.

Intent-to-Treat (ITT) Population: all randomized participants

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.

ITT Population

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.

ITT Population

The number of participants requiring surgery was measured.

ITT Population

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.

As-Treated Population: randomized participants who received at least one dose of study treatment, as actually received

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.

As-Treated Population

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.
