Measure
Edoxaban
Pediatric patients who were randomized to edoxaban treatment. Edoxaban was administered as 15 or 30 mg tablets for participants 12 years of age to \<18, and 60 mg edoxaban suspension for oral administration to participants under 12 years of age.
Standard of Care
Pediatric patients who were randomized to standard of care (SOC) treatment. Standard of care may have included low molecular weight heparin (LMWH), vitamin K antagonist (VKA), or synthetic pentasaccharide (SP) Xa inhibitors.

Timeframe: Randomization to Month 3

Population: Symptomatic recurrent VTE was assessed in the modified intent-to-treat population (mITT).

Diagnosis of recurrent venous thromboembolism (VTE) requires the confirmation by diagnostic imaging and at least one of the symptoms of VTE from such areas as lower or upper extremity, catheter related thrombosis, pulmonary embolism, or sinovenous thrombosis.

PRIMARY outcome

Timeframe: Randomization to Month 3

Population: Change in thrombotic burden was assessed in the modified intent-to-treat population (mITT).

No change or extension of thrombotic burden as assessed by quantitative diagnostic imaging of the index qualifying VTE thrombus at baseline and at Month 3. Imaging criteria for VTE included: - Abnormal compression ultrasonography where compression had been normal or, if non-compressible during screening, an increase in diameter of the thrombus during full compression; - An extension of the echogenic intra-luminal thrombus or absence of flow in the central venous system on Doppler ultrasonography. - An extension of an intraluminal filling defect, or a new intraluminal filling defect, or an extension of non-visualization of veins in the presence of a sudden cut-off on venography. - An extension of an intraluminal filling defect, or a new intraluminal filling defect on computed tomography angiogram (CTA).

Population: Deep vein thrombosis, catheter-related thrombosis, sino-venous thrombosis, and pulmonary embolism were assessed in the modified intent-to-treat (mITT) population.

Deep vein thrombosis was assessed by ultrasonography or magnetic resonance venography (MRV), catheter-related thrombosis was assessed by ultrasonography or echocardiography, sino-venous thrombosis was assessed by brain MRI, and pulmonary embolism was assessed by nuclear ventilation/perfusion (V/Q) scanning.

SECONDARY outcome

Timeframe: Randomization to Month 3

Population: Major and clinically relevant non-major bleeding events were assessed in the Safety Analysis Set.

Any bleeding event defined as major and clinically relevant non-major bleeding (CRNM) events was reported. Major bleeding was defined as defined as a composite of any of the following: fatal bleeding; and/or symptomatic bleeding in critical area or organ such as intracranial, intra-spinal, intraocular, retroperitoneal, intra-articular, pulmonary, or pericardial, or intramuscular with compartment syndrome; and/or bleeding that causes a decrease in hemoglobin of at least 2 g/dL or more, or leading to transfusion of the equivalent of two or more units of whole blood or red blood cells. CRNM was defined as acute or sub-acute clinically overt bleed that does not meet the criteria for a major bleed but prompts a clinical response, in that it leads to at least one of the following: a hospital admission for bleeding; a physician-guided medical or surgical treatment for bleeding or a change in antithrombotic therapy (including interruption or discontinuation of study drug).

Edoxaban
n=145 Participants
Pediatric patients who were randomized to edoxaban treatment. Edoxaban was administered as 15 or 30 mg tablets for participants 12 years of age to \<18, and 60 mg edoxaban suspension for oral administration to participants under 12 years of age.
Standard of Care
n=141 Participants
Pediatric patients who were randomized to standard of care (SOC) treatment. Standard of care may have included low molecular weight heparin (LMWH), vitamin K antagonist (VKA), or synthetic pentasaccharide (SP) Xa inhibitors.

SECONDARY outcome

Timeframe: From randomization up to Month 12

Population: All bleeding events were assessed in the Safety Analysis Set.

All bleeding events included major bleeding defined as a composite of any of the following: fatal bleeding; and/or symptomatic bleeding in critical area or organ such as intracranial, intra-spinal, intraocular, retroperitoneal, intra-articular, pulmonary, or pericardial, or intramuscular with compartment syndrome; and/or bleeding that causes a decrease in hemoglobin of at least 2 g/dL or more, or leading to transfusion of the equivalent of two or more units of whole blood or red blood cells (RBCs), clinically relevant non-major bleeding defined as acute or sub-acute clinically overt bleed that does not meet the criteria for a major bleed but prompts a clinical response, in that it leads to at least one of the following: a hospital admission for bleeding; a physician-guided medical or surgical treatment for bleeding or a change in antithrombotic therapy (including interruption or discontinuation of study drug), nuisance bleeding, or a combination of bleeding events.
