Hokusai Study in Pediatric Patients With Confirmed Venous Thromboembolism (VTE)
United States, Argentina, Brazil290 participantsStarted 2017-03-27
Plain-language summary
This is an event driven Phase 3, prospective, randomized, open-label, blinded endpoint evaluation (PROBE) parallel group study in subjects with confirmed VTE. This study is designed to evaluate the pharmacokinetics (PK) and pharmacodynamics (PD) of edoxaban and to compare the efficacy and safety of edoxaban against standard of care in pediatric subjects with confirmed VTE.

Inclusion criteria
. Male or female pediatric subjects between birth (defined as 38 weeks gestational age) and less than 18 years of age at the time of consent.
. Pediatric subjects with the presence of documented VTE confirmed by appropriate diagnostic imaging and requiring anticoagulant therapy for at least 90 days.
. Subjects must have received at least 5 days of heparin therapy prior to randomization to treat the newly identified index VTE. In addition, prior to being randomized to edoxaban or SOC, subjects initially treated with VKA are recommended to have an international normalized ratio (INR) \< 2.0.
. Subject and/or parent(s)/legal guardian(s) or legally acceptable representative is informed and provides signed consent for the child to participate in the study.
. Female subjects who have menarche must test negative for pregnancy at Screening and must consent to avoid becoming pregnant by using an approved contraception method throughout the study.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.

Number of Participants With No Change or Extension of Thrombotic Burden During the Main Treatment Period Following Edoxaban or Standard of Care Treatment (Adjudicated Composite)
. Subjects with active bleeding or high risk of bleeding contraindicating treatment with LMWH, SP Xa inhibitors, VKAs, or direct oral anticoagulants (DOACs; identified high risk of bleeding during prior experimental administration of DOACs).
. Subjects who have been or are being treated with thrombolytic agents, thrombectomy or insertion of a caval filter for the newly identified index VTE.
. Administration of antiplatelet therapy is contraindicated in both arms except for low dose aspirin defined as 1-5 mg/Kg/day with maximum of 100 mg/day.
. Administration of rifampin is prohibited during the study and subjects on concomitant use of rifampin are excluded.
. Subjects with hepatic disease associated with coagulopathy leading to a clinically relevant bleeding risk (aPTT \> 50 seconds or international normalized ratio \[INR\] \> 2.0 not related to anticoagulation therapy) or alanine aminotransferase (ALT) \> 5 × the upper limit of normal (ULN) or total bilirubin \> 2 × ULN with direct bilirubin \> 20% of the total at Screening Visit.
. Subjects with glomerular filtration rate (GFR) \< 30% of normal for age and size as determined by the Schwartz formula.
. Subjects with stage 2 hypertension defined as blood pressure (BP) systolic and/or diastolic confirmed \> 99th percentile + 5 mmHg.
. Subject with thrombocytopenia \< 50 × 109/L at Screening Visit. Subjects with a history of heparin-induced thrombocytopenia may be enrolled in the study at the Investigator's discretion.
