Overview
Brief Summary
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.

Outcomes
Primary Outcomes
Composite Primary Endpoint
Time Frame: From the time of randomisation until Week 12, 84 days after randomisation including a visit window of 7 days.
The primary endpoint was the combined endpoint of the proportions of patients with: * Complete thrombus resolution * Freedom from recurrent VTE * Freedom from mortality related to VTE. The events outlined in the above combined primary endpoint were assessed by radiologists or other such qualified clinicians using an appropriate method such as ultrasound, echocardiography, venography, or CT scan, based on the location of the thrombus and the test used to perform the baseline assessment. The primary efficacy endpoint contained 3 components. Each component was evaluated separately, and only if the criteria for all 3 components were satisfied, the primary endpoint was considered achieved.
Secondary Outcomes
- Steady State Plasma Concentrations of Total Dabigatran at Visit 3(From the time of randomisation until visit 3)
- Steady State Plasma Concentrations After at Least 3 Days Following Any Dabigatran Etexilate Dose Adjustment(From the time of randomisation until Week 12, 84 days after randomisation including a visit window of 7 days.)
- Frequency of Dose Adjustment During the Treatment Phase(From first administration of trial medication until last administration of trial medication +6 days (residual effect period).)
- Frequency of Patients Switching the Type of Anti-coagulation Therapy Including Dabigatran Etexilate to Standard of Care Treatment and Switching From One Standard of Care Treatment to Another(From first administration of trial medication until last administration of trial medication +6 days (residual effect period).)
- Freedom From Thrombus Progression at End of Therapy Compared With Baseline(From the time of randomisation until Week 12, 84 days after randomisation including a visit window of 7 days.)
- Freedom From Major Bleeding Events (MBEs)(From first administration of trial medication until last administration of trial medication +6 days (residual effect period). Up to 97 days.)
- All Bleeding Events(From first administration of trial medication until last adminstration of trial medication +6 days (residual effect period). Up to 97 days.)
- All-cause Mortality(From first administration of trial medication until last administration of trial medication +6 days (residual effect period). Up to 97 days.)
- All Components of the Primary Efficacy Endpoint(From the time of randomisation until Week 12, 84 days after randomisation including a visit window of 7 days.)
- Assessment of the Acceptability of an Age-appropriate Formulation at End of Therapy (Capsules)(Assessment at the last study visit at day 84 (+- 7 days), or at day of early termination.)
- Assessment of the Acceptability of an Age-appropriate Formulation at End of Therapy (Pellets)(Assessment at the last study visit at day 84 (+- 7 days), or at day of early termination.)
- Assessment of the Acceptability of an Age-appropriate Formulation at End of Therapy (Oral Liquid Formulation - OLF)(Assessment at the last study visit at day 84 (+- 7 days), or at day of early termination.)
