About this study

Official title: An Open-label, Randomised, Parallel-group, Multicentre, Observational Trial to Evaluate Safety and Efficacy of Edoxaban Tosylate in Children From 38 Weeks Gestational Age to Less Than 18 Years of Age With Cardiac Diseases at Risk of Thromboembolic Events

A committee will judge the safety and effectiveness of edoxaban and the regular treatment (standard of care).

All children in the study will receive free treatment. They will have a 2 in 3 chance to receive edoxaban, and a 1 in 3 chance to receive the standard of care for preventing blood clots.

The study will find out if edoxaban is safer and more effective than the standard of care.

Read the detailed description

The primary objective is to compare the safety of edoxaban with the standard of care (SOC) in pediatric subjects with cardiac diseases at risk of thromboembolic complications who need primary or secondary anticoagulant prophylaxis with regard to the combination of major and clinically relevant non-major (CRNM) bleeding per International Society on Thrombosis and Haemostasis [ISTH] definition.

The key secondary objective is to compare the efficacy of edoxaban against SOC with regard to the development of symptomatic thromboembolic events (TE) in the systemic arterial or venous pathways including deep vein thrombosis (DVT), pulmonary embolism (PE), stroke, intracardiac thrombus and myocardial infarction (MI), and asymptomatic intracardiac thrombus identified by cardiac imaging.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With Adjudicated Bleeding Events Within the Main Treatment Period

    Adjudicated bleeding events included major and clinically-relevant non-major (CRNM) bleeding events per International Society on Thrombosis and Haemostasis (ISTH) definition occurring within the main treatment period. Based on modified ISTH recommendations, major bleeding is defined as a composite (ie, any) of the following: fatal bleeding; and/or symptomatic bleeding in a critical area or organ; and/or bleeding causing a decrease in hemoglobin level of >2 g/dL, or leading to transfusion of the equivalent of ≥2 units of whole blood or red cells. A CRNM bleed is an 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, or a physician guided medical or surgical treatment for bleeding, or a change in antithrombotic therapy. Minor bleeding is any other overt bleeding event that does not meet criteria for either major or CRNM bleeding.

    Measured: Date of first dose of study drug up to the Month 4 or to the date of last dose of study drug if study treatment was discontinued, whichever was earlier

Secondary outcomes (7)
  1. Number of Participants With Symptomatic Thromboembolic Events (TE) in the Systemic Arterial or Venous Pathways Within the Main Treatment Period

    Symptomatic thromboembolic events (TE) in the systemic arterial or venous pathways include deep vein thrombosis (DVT), pulmonary embolism (PE), stroke, intracardiac thrombus, and myocardial infarction (MI).

    Measured: Date of first dose of study drug up to the Month 4 or to the date of last dose of study drug if study treatment was discontinued, whichever was earlier

  2. Number of Participants Who Died as a Result of Thromboembolic Event Within the Main Treatment Period

    Symptomatic thromboembolic events (TE) in the systemic arterial or venous pathways include deep vein thrombosis (DVT), pulmonary embolism (PE), stroke, intracardiac thrombus, and myocardial infarction (MI).

    Measured: Date of first dose of study drug up to the Month 4 or to the date of last dose of study drug if study treatment was discontinued, whichever was earlier

  3. Number of Participants Who Died as a Result of Any Cause (All-Cause Mortality) Within the Main Treatment Period

    Death due to any cause (all-cause mortality) was assessed.

    Measured: Date of first dose of study drug up to the Month 4 or to the date of last dose of study drug if study treatment was discontinued, whichever was earlier

  4. Number of Participants With Adjudicated Bleeding Events During the Extension Period

    Adjudicated bleeding events included major and clinically-relevant non-major (CRNM) bleeding events per International Society on Thrombosis and Haemostasis (ISTH) definition occurring within the main treatment period. Based on modified ISTH recommendations, major bleeding is defined as a composite (ie, any) of the following: fatal bleeding; and/or symptomatic bleeding in a critical area or organ; and/or bleeding causing a decrease in hemoglobin level of >2 g/dL, or leading to transfusion of the equivalent of ≥2 units of whole blood or red cells. A CRNM bleed is an 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, or a physician guided medical or surgical treatment for bleeding, or a change in antithrombotic therapy. Minor bleeding is any other overt bleeding event that does not meet criteria for either major or CRNM bleeding.

    Measured: Month 4 up to Month 13

  5. Number of Participants With Symptomatic Thromboembolic Events (TE) in the Systemic Arterial or Venous Pathways During the Extension Period

    Symptomatic thromboembolic events (TE) in the systemic arterial or venous pathways include deep vein thrombosis (DVT), pulmonary embolism (PE), stroke, intracardiac thrombus, and myocardial infarction (MI).

    Measured: Month 4 up to Month 13

  6. Number of Participants Who Died as a Result of Thromboembolic Event During the Extension Period

    Symptomatic thromboembolic events (TE) in the systemic arterial or venous pathways include deep vein thrombosis (DVT), pulmonary embolism (PE), stroke, intracardiac thrombus, and myocardial infarction (MI).

    Measured: Month 4 up to Month 13

  7. Number of Participants Who Died as a Result of Any Cause (All-Cause Mortality) During the Extension Period

    Death due to any cause (all-cause mortality) was assessed.

    Measured: Month 4 up to Month 13
