Drug Information available for: Rivaroxaban

Arm Intervention/treatment
Experimental: BAY59-7939
Rivaroxaban (tablets and oral suspension) Dose: Age and body weight-adjusted dosing of rivaroxaban to achieve a similar exposure as that observed in adults treated for venous thromboembolism (VTE) with 20 mg rivaroxaban.
Drug: Rivaroxaban (Xarelto, BAY59-7939)
Age and body weight-adjusted dosing equivalent to 20 mg rivaroxaban in adults, once daily or twice daily, as tablets

Drug: Rivaroxaban (Xarelto, BAY59-7939)
Age and body weight-adjusted dosing equivalent to 20 mg rivaroxaban in adults, once daily, twice daily or three times daily, as oral suspension

Experimental: Standard of Care
Subcutaneous low molecular weight heparin (LMWH), subcutaneous fondaparinux and/or oral vitamin K antagonist (VKA) Dose : as per standard of care
Drug: Standard of Care

LMWH (low molecular weight heparin) or fondaparinux or vitamin K antagonist (VKA) therapy.

dose : as per standard of care





Primary Outcome Measures :
  1. Composite number of all symptomatic recurrent venous thromboembolism. [ Time Frame: Up to 12 months ]
    Assessed by a central independent adjudication committee (CIAC)

  2. Composite number of overt major and clinically relevant non-major bleeding. [ Time Frame: Up to 12 months ]
    Assessed by a central independent adjudication committee (CIAC)


Secondary Outcome Measures :
  1. Composite number of all symptomatic recurrent venous thromboembolism and asymptomatic deterioration on repeat imaging. [ Time Frame: Up to 12 months ]
    Assessed by a central independent adjudication committee (CIAC)

Ages Eligible for Study:   up to 17 Years   (Child)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No
Criteria

Inclusion Criteria:

  • Children aged birth to < 18 years with confirmed venous thromboembolism who receive initial treatment with therapeutic dosages of UFH (unfractionated heparin), LMWH (low molecular weight heparin) or fondaparinux and require anticoagulant therapy for at least 90 days. However, children aged birth to < 2 years with catheter-related thrombosis require anticoagulant therapy for at least 30 days.
  • For children younger than 6 months:

    • Gestational age at birth of at least 37 weeks.
    • Oral feeding/nasogastric/gastric feeding for at least 10 days.
    • Body weight ≥2600 g

Exclusion Criteria:

  • Active bleeding or bleeding risk contraindicating anticoagulant therapy
  • An estimated glomerular filtration rate (eGFR) < 30 mL/min/1.73 m*2 (in children younger than 1 year, serum creatinine results above 97.5th percentile excludes participation)
  • Hepatic disease which is associated with either: coagulopathy leading to a clinically relevant bleeding risk, or ALT> 5x upper level of normal (ULN) or total bilirubin > 2x ULN with direct bilirubin > 20% of the total
  • Platelet count < 50 x 109/L
  • Sustained uncontrolled hypertension defined as > 95th age percentile
  • Life expectancy < 3 months
  • Concomitant use of strong inhibitors of both cytochrome P450 isoenzyme 3A4 (CYP3A4) and P-glycoprotein (P-gp), including but not limited to all human immunodeficiency virus protease inhibitors and the following azole antimycotics agents: ketoconazole, itraconazole, voriconazole, posaconazole, if used systemically
  • Concomitant use of strong inducers of CYP3A4, including but not limited to rifampicin, rifabutin, phenobarbital, phenytoin and carbamazepine
  • Childbearing potential without proper contraceptive measures, pregnancy or breast feeding
