The main objectives of this large phase IIb/III paediatric study are to assess the efficacy and safety of dabigatran etexilate relative to standard of care and to document the appropriateness of the proposed dabigatran etexilate dosing algorithm for use in patients from birth to less than 18 years of age.
Male or female subjects 0 to less than 18 years of age at the time of informed consent / assent
Documented diagnosis of clinically stable VTE (e.g. DVT, PE, central line thrombosis, sinus vein thrombosis) per investigator judgment, initially treated (minimum of 5 to 7 days, but not longer than 21 days) with parenteral anticoagulation therapy, such as unfractionated heparin (UFH) or a low molecular weight heparin (LMWH).
Clinical indication for at least 3 month of treatment with anticoagulants for the VTE episode defined under the above inclusion criterion.
Written informed consent provided by the patient's parent or legal guardian and assent provided by the patient (if applicable) at the time of informed consent form (ICF) signature according to local regulations.
Conditions associated with an increased risk of bleeding
Renal dysfunction (eGFR < 50 mL/min/1.73m^2 using the Schwartz formula) or requirement for dialysis. eGFR retesting during the screening period is allowed (once).
Active infective endocarditis
Subjects with a heart valve prosthesis requiring anticoagulation.
Active liver disease, including known active hepatitis A, B or C or, Persistent alanine aminotransferase (ALT) or aspartate transaminase (AST) or alkaline phosphatase (AP) > 3 × upper limit of normal (ULN) within 3 months of screening
Pregnant or breast feeding females. Females who have reached menarche and are not using a medically accepted contraceptive method per local guidelines. Acceptable methods of birth control must be used in a correct and consistent manner
Patients in stratum 3 (0 to < 2 years) with gestational age at birth < 37 weeks or with body weight lower than the 3rd percentile
Anemia (hemoglobin < 80g/L) or thrombocytopenia (platelet count < 80 x 109/L) at screening. Transfusions during the screening period are allowed, provided that a satisfactory hemoglobin or platelet level is attained prior to visit 2
Patients who have taken prohibited or restricted medication within one week of the first dose of study medication other than medication for prior VTE treatment and P-glycoprotein inhibitors..
Patients who have received an investigational drug in the past 30 days prior to screening
Patients who are allergic/sensitive to any component of the study medication including solvent
Patients or parents/legal guardians considered unreliable to participate in the trial per investigator judgment or any condition which would present a safety hazard to the patient based on investigator judgment
Patients or parents/legal guardians who are unwilling or unable to undergo or permit repeat of the baseline imaging tests required to confirm thrombus resolution at study day 84 (or eEOT, whichever comes first) or in whom repeating such imaging tests at these pre-specified time points may not be medically in the patient's best interest. Examples may include unwarranted radiation exposure as a result of a repeat CT scan at day 84 for a patient with an isolated case of pulmonary embolism evaluated at baseline solely by a CT scan. In such cases, the baseline radiological assessment (e.g. CT) may be supplemented with an acceptable non-radiological assessment at baseline (e.g. MRI) which could then be repeated at day 84 hence alleviating any potential unwarranted radiation exposure.
