Brief Summary:
This is the first evaluation of edoxaban in pediatric subjects. In this Phase 1 study, a single dose of edoxaban will be given to pediatric subjects who require anticoagulant therapy to see what the body does to the drug (pharmacokinetics) and what the drug does to the body (pharmacodynamics), and to compare if these effects are similar to those observed in adults.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Deep Vein Thrombosis Venous Thromboembolism | Drug: Edoxaban low dose Drug: Edoxaban high dose | Phase 1 |
Phase 1, open-label, multiple-center study in pediatric patients from 0 to < 18 years of age. Patients will receive a single dose of edoxaban to match either the 30 mg (low dose) or the 60 mg (high dose) exposure in adults. Exact doses will be selected during the study on the basis of PK modeling of emerging data. If unanticipated exposures are observed, the target doses may be modified to best match expected exposure response relationships observed in adults.
Enrollment in the study will start with the low dose, highest age group (adolescents) and will continue from low to high dose in each age group and from higher to lower age groups. Enrollment in the next dose/age cohort will begin after 50% of the subjects have completed the previous dose/age cohort.
Age cohorts and dose groups: (6 participants each in low and high dose groups, for a total of 12 participants per age cohort)
- 12 to < 18 years of age
- 6 to <12 years of age
- 2 to <6 years of age
- 6 months to <2 years of age
- 0 to <6 months of age

Primary Outcome Measures :
- Pharmacokinetics (PK)- Apparent systemic clearance (CL/F) [ Time Frame: within 36 hours postdose ]A sampling windows approach will be used: 0.25 to 1, 1.5 to 3, 4 to 8, 9 to 14, and 24 to 36 hours postdose (total of 5 blood samplings)
- PK- Apparent volume of distribution (V/F) [ Time Frame: within 36 hours postdose ]A sampling windows approach will be used: 0.25 to 1, 1.5 to 3, 4 to 8, 9 to 14, and 24 to 36 hours postdose (total of 5 blood samplings)
- PK- Area under the concentration-time curve (AUC) for edoxaban and metabolites [ Time Frame: within 36 hours postdose ]A sampling windows approach will be used: 0.25 to 1, 1.5 to 3, 4 to 8, 9 to 14, and 24 to 36 hours postdose (total of 5 blood samplings); metabolites include D21-2393, D21-3231, D21-1402, and D21-2135
- PK- Metabolite/parent ratios for AUC [ Time Frame: within 36 hours postdose ]A sampling windows approach will be used: 0.25 to 1, 1.5 to 3, 4 to 8, 9 to 14, and 24 to 36 hours postdose (total of 5 blood samplings); metabolites include D21-2393, D21-3231, D21-1402, and D21-2135
Secondary Outcome Measures :
- Pharmacodynamic (PDy)- Mean prothrombin time (PT) [ Time Frame: Predose and within 36 hours postdose ]Predose and immediately after simultaneously scheduled PK blood samples, using a dosing windows approach: 0.25 to 1, 1.5 to 3, 4 to 8, 9 to 14, and 24 to 36 hours postdose (total of 6 blood samplings)
- PDy- Mean activated partial thromboplastin time (aPTT) [ Time Frame: Predose and within 36 hours postdose ]Predose and immediately after simultaneously scheduled PK blood samples, using a dosing windows approach: 0.25 to 1, 1.5 to 3, 4 to 8, 9 to 14, and 24 to 36 hours postdose (total of 6 blood samplings)
