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. presence or history of cancer;
  3. systemic lupus erythematosus
  4. known pulmonary embolism (PE), except when limited to peripheral cavitary lesions representing septic emboli; (N.B. imaging for PE should only have been based upon clinical signs/symptoms, and is not a study procedure or requirement)
  5. Use of, or intent to use, thrombolytic therapy
  6. Patients with congenital cardiac disease involving a single or hypoplastic ventricle or otherwise requiring an intracardiac 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.
