Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. 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.

Ages Eligible for Study

20 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Acute symptomatic proximal DVT with evidence of proximal thrombosis
  • Acute symptomatic PE with evidence of thrombosis in segmental or more proximal branches

Exclusion Criteria:

  • Active bleeding or high risk for bleeding contraindicating treatment with UFH and a VKA.
  • Uncontrolled hypertension: systolic blood pressure > 180 mm Hg or diastolic blood pressure > 110 mm Hg
  • Subjects requiring dual anti-platelet therapy

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
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
Time Frame: 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.
Baseline to Week 24

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
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
Time Frame: Baseline to Week 24
VTE-related death was defined as a death caused by documented PE which was diagnosed with objective testing or autopsy, or an unexplained death for which DVT/PE could not be ruled out as the cause. "Intended Treatment Period" was the period starting on the day of randomization and ending at either 2 days after the last dose of the study drug or Day 168/Week 24, whichever came late.
Baseline to Week 24
Number of Participants With Adjudicated Thrombotic Burden Worsened in Acute Symptomatic Proximal Deep Venous Thrombosis (DVT)
Time Frame: Baseline to Week 24
Computed tomography venography (CTV) and compression ultrasound (CUS) were used to assess thrombotic burden in the participants with DVT and the results were classified as improved, no change, or worsened. The timings of CTV and CUS examinations were at Week 12 and Weeks 2, 12 and 24.
Baseline to Week 24
Number of Participants With Adjudicated Thrombotic Burden Worsened in Acute Symptomatic Pulmonary Embolism (PE)
Time Frame: Baseline to Week 24
Computed tomography pulmonary angiography (CTPA) was used to assess thrombotic burden in the participants with PE and the results were classified as improved, no change, or worsened. The timings of CTPA examinations were Weeks 2, 12 and 24.
Baseline to Week 24
Number of Participants With Adjudicated Major Bleeding Events ［Per International Society on Thrombosis and Homeostasis (ISTH) Definition］During the Treatment Period
Time Frame: 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.
Baseline to Week 24
Number of Participants With Adjudicated All Bleeding Events During the Treatment Periods
Time Frame: Baseline to Week 24
All bleeding events consisted of major bleeding (per Interactional Society on Thrombosis and Homeostasis ［ISTH］ Definition), clinically relevant non-major (CRNM) and minor bleeding. All acute clinically overt bleeding events not meeting the criteria for either major bleeding or CRMN bleeding were classified as minor bleeding.
Baseline to Week 24

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
