Brief Summary:
The Kids-DOTT trial is a randomized controlled clinical trial whose primary objective is to evaluate non-inferiority of shortened-duration (6 weeks) versus conventional-duration (3 months) anticoagulation in children with first-episode acute venous thrombosis. The first stage of the trial has consisted of a pilot/feasibility component, which then continues as the definitively-powered trial.

Condition or disease Intervention/treatment Phase
Venous Thrombosis Other: Shortened duration (6 weeks) of anticoagulant therapy Other: Conventional duration (3 months) of anticoagulant therapy Other: No Intervention Phase 3

Arm Intervention/treatment
Experimental: Intervention: A
Patients with non-occlusive thrombus or resolved thrombosis at 6 weeks.
Other: Shortened duration (6 weeks) of anticoagulant therapy
Subjects with evidence of non-occlusive or resolved thrombus at 6 weeks time will be randomized to receive a total duration of anticoagulant therapy of 6 weeks.

Active Comparator: B
Patients with non-occlusive thrombus or resolved thrombosis at 6 weeks.
Other: Conventional duration (3 months) of anticoagulant therapy
Subjects with evidence of non-occlusive or resolved thrombus at 6 weeks time will be randomized to receive a total duration of anticoagulant therapy of 3 months.

Parallel Cohort: Persistent Occlusive Thrombosis
Patients with completely occlusive thrombosis at 6 weeks.
Other: No Intervention
Subjects with evidence of persistent thrombus at 6 weeks time will remain on anticoagulant therapy for 3-6 months at the discretion of their treating physician.

Parallel Cohort: Persistent Antiphospholipid Antibody
Patients with persistent Positive Antiphospholipid Antibody at 6 weeks.
Other: No Intervention
Subjects with evidence of persistent antiphospholipid antibody at 6 weeks will remain on anticoagulant therapy for 3 months to indefinite duration, at the discretion of their treating physician.

Primary Outcome Measures :
  1. Bivariate endpoint. [ Time Frame: 1 Year ]

    Primary efficacy endpoint is the risk of symptomatic, radiologically-confirmed recurrent venous thromboembolism.

    Primary safety endpoint is clinically-relevant bleeding (major + clinically-relevant non-major).

Secondary Outcome Measures :
  1. Prevalence/severity of post-thrombotic syndrome. [ Time Frame: 1 and 2 Years ]
    PTS is measured using a standardized validated pediatric outcome instrument (Manco-Johnson instrument). Both PTS and clinically-significant PTS will be captured as secondary endpoints.

Ages Eligible for Study:   up to 20 Years   (Child, Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Children (birth to <21 years of age) with radiologically-confirmed acute venous thrombosis in the past 30 days
  2. In the opinion of the investigator, the venous thrombosis was a provoked (i.e., non-spontaneous) event (e.g.: hospitalization; Central venous catheterization; infection; dehydration; surgery; trauma; immobility; use of estrogen-containing oral contraceptive pills; flare of autoimmune/rheumatologic condition).

Exclusion Criteria:

  1. Prior episode of VTE
  2. Malignancy that, in the opinion of the treating oncologist, is not in remission, or for which chronic anticoagulation is being administered/anticipated to be initiated within 6 months (note: remission may exist on or off anti-neoplastic therapy)
  3. Systemic lupus erythematosus
  4. Pulmonary embolism that is not accompanied by DVT or is more proximal than segmental branches of the pulmonary artery
  5. Use of, or intent to use, thrombolytic therapy
  6. History of congenital cardiac disease for which chronic anticoagulation is being administered/ anticipated to be initiated within 6 months (e.g., for select patients or centers, in the setting of a single or hypoplastic ventricle or surgically-established cardiac shunt)
  7. Moderate/severe anticoagulant deficiency as defined by any one of the following:

    1. protein C <20 IU/dL if patient is ≥3 months of age, or protein C below lower limit of detection if patient is <3 months of age;
    2. antithrombin <30 IU/dL if patient is ≥3 months of age, or antithrombin below lower limit of detection if patient is <3 months of age;
    3. protein S (free antigen or activity) <20 IU/dL.
