An early stage study looking at how much betrixaban gets into the blood of young people after they take a single capsule, and to see if it is safe to do so.
- Conditions
- Pediatric patients who are assessed to be at risk for Venous thromboembolism (VTE) but does not require immediate anticoagulant therapy, for example:a. Has previous thrombosis and completed a course of anti-coagulant therapy, and is considered to have a risk for recurrence of VTE, orb. Has any stable disease with a risk for arterial or venous thrombotic disorder, orc. Has any functional CVAD (Central Venous Access Device) in the upper or lower venous system.MedDRA version: 20.0Level: PTClassification code 10053468Term: Anticoagulant therapySystem Organ Class: 10042613 - Surgical and medical proceduresTherapeutic area: Diseases [C] - Blood and lymphatic diseases [C15]

1. Patient received any dose of anticoagulant therapy within 7 days of Day 1.
2. Patient has active bleeding or has a comorbid disorder that places the patient at high risk for bleeding, including a positive fecal occult blood test or hematuria within 30 days prior to Day -1.

6. Patient has hepatic disease associated with one or more of the following:
? Transaminase levels = 2.5 × Upper Limit of Normal (ULN) or bilirubin = 1.5 × ULN at baseline.
? Coagulopathy leading to a clinically relevant bleeding risk, or hepatic transaminase level of > 2 × ULN or total bilirubin > 2 × ULN with direct bilirubin > 20% of the total.
