Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Recurrent or New Symptomatic Venous Thromboembolism (VTE)
Time Frame: From Day 1 to Day 90 (±7 days)
VTE (pulmonary thromboembolism [PE] and/or deep vein thrombosis [DVT]) was adjudicated blindly by the Central Independent Adjudication Committee of Efficacy (CIACE).
From Day 1 to Day 90 (±7 days)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Percentage of Participants With Recurrent or New Symptomatic/Asymptomatic VTE (by Type)
Time Frame: From Day 1 to Day 90 (±7 days)
VTE (pulmonary thromboembolism [PE] and/or deep vein thrombosis [DVT]) was adjudicated blindly by the CIACE.
From Day 1 to Day 90 (±7 days)
Percentage of Participants With Perfusion Lung Scan Results Scored as Improved, no Change, or Worse Compared to Baseline
Time Frame: Baseline, single day between Day 5 and Day 10 (the day when the medication [FPX or UFH] was finished /discontinued) (±1 day)
Classifications of "Improved," "No change," or "Worse" were adjudicated blindly by the CIACE.
Baseline, single day between Day 5 and Day 10 (the day when the medication [FPX or UFH] was finished /discontinued) (±1 day)
Total Perfusion Score at Baseline and Mean Change From Baseline at Day 5-10
Time Frame: Baseline, single day between Day 5 and Day 10 (the day when the medication [FPX or UFH] was finished /discontinued) (±1 day)
Change from baseline was calculated as the score on the day medication was finished/discontinued (anywhere from Day 5 to Day 10) minus the baseline score. The perfusion score (0: no perfusion; 0.25, 0.5, 0.75, 1: normal) in each of the six lobes of the lung was adjudicated blindly by the CIACE. Total perfusion score (r) was calculated as: r = (0.25 x right lower lobe) + (0.12 x right middle lobe) + (0.18 x right upper lobe) + (0.20 x left lower lobe) + (0.12 x lingula) + (0.13 x left upper lobe).
Baseline, single day between Day 5 and Day 10 (the day when the medication [FPX or UFH] was finished /discontinued) (±1 day)
Percentage of Participants With a Bleeding Event
Time Frame: Initial treatment period (from the first dose of FPX/UFH to N days after the last dose of FPX/UFH; specified based on creatinine clearance [CLcr]; N=3, CLcr >=50 mL/min; N=4, 30 =< CLcr < 50 mL/min; N=9, CLcr < 30 mL/min).
Bleeding events (major bleeding [clinically overt bleeding with fatality, location in a critical organ, a fall in hemoglobin >=2 grams (g)/deciliter (dL), or a transfusion >=2 units]; minor bleeding [clinically overt bleeding and not adjudicated as major bleeding], and no bleeding) were adjudicated blindly by the Central Independent Adjudication Committee of Safety (CIACS).
Initial treatment period (from the first dose of FPX/UFH to N days after the last dose of FPX/UFH; specified based on creatinine clearance [CLcr]; N=3, CLcr >=50 mL/min; N=4, 30 =< CLcr < 50 mL/min; N=9, CLcr < 30 mL/min).
