Further study details as provided by Eisai Inc.:

Primary Outcome Measures:
  • Efficacy: Thrombus resolution at the end of study or early termination visit will be measured by repeating the same imaging method used at baseline. [ Time Frame: 90 days ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Safety Outcomes will consist of major bleeding episodes, recurrent DVT/Pulmonary embolism and unexpected serious adverse events (SAEs). [ Time Frame: 90 days ] [ Designated as safety issue: Yes ]

Estimated Enrollment: 50
Study Start Date: February 2010
Estimated Primary Completion Date: December 2015 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: 1 Drug: Fragmin
Subject's age 0-2 months (newborns) will receive an initial dose of 125 IU/kg. Subject's age 2 months to 12 months (infants) will receive an initial dose of 150 IU/kg. Subjects age 12 months through 12 years (preschool and school) will receive an initial dose of 125 IU/kg. Subjects age 12 to 18 years (teen) will receive an initial dose of 100 IU/kg. All subjects will have dose adjustments in 25 IU/kg increments/decrements based upon an anti-Xa therapeutic goal range of 0.5 - 1.0 U/mL.
Other Name: Dalteparin sodium


Ages Eligible for Study:   up to 18 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. Have an active malignancy (defined as a diagnosis of cancer, other than basal cell or squamous cell carcinoma of the skin).
  2. Have been objectively diagnosed with thrombosis involving a deep vein (documented using compression ultrasound with Doppler [CUD], computed tomography with/without venography [CT/CTV], magnetic resonance imaging with/without venography [MRI/MRV], conventional venography [CV]) or pulmonary artery (ventilation-perfusion scan [V/Q], spiral CT angiography [SCTA], or conventional pulmonary angiogram [CPA]) within the 96 hours of enrollment, and require anticoagulation therapy.
  3. Are judged clinically to require anticoagulation therapy.
  4. Are in the age range of greater than or equal to 36 weeks gestation and less than 19 years.
  5. Have given signed informed consent (and assent, as appropriate) to participate prior to enrollment.

Exclusion Criteria:

  1. Weight less than or equal to 3.0 kg or greater than 100 kg.
  2. Platelet count less than or equal to 50,000/mm3 (despite appropriate medical measures to support platelet count).
  3. Received oral anticoagulant therapy within 72 hours of enrollment.
  4. History of administration of therapeutic doses of LMWH or unfractionated heparin for a treat period of greater than 96 hours (or greater than 8 doses of LMWH) for the qualifying VTE.
  5. Received unfractionated heparin within 3 hours, or LMWH within 15 hours of the first dose of dalteparin.
  6. Acute VTE intervention which includes thrombolytic therapy.
  7. Major bleeding at the time of screening or enrollment or an unacceptably high risk of bleeding at the discretion of the investigator.
  8. aPTT greater than 5 seconds above ULN, and that corrects to within normal limits upon 1:1 mixing with normal plasma.
  9. PT greater than 2 seconds above ULN, and that corrects to within normal limits upon 1:1 mixing with normal plasma.
  10. Calculated creatinine clearance (Schwartz method) less than 60 mL/min in subjects greater than 1 month of age.
  11. Uncontrolled hypertension characterized by a sustained systolic pressure or diastolic pressure greater than 99th percentile of age- and height-related norms.
  12. History of heparin-induced thrombocytopenia (HIT).
  13. Any condition in which the investigator feels the subject is unsafe or inappropriate for study participation.
  14. Insufficient subcutaneous tissue to facilitate subcutaneous drug administration.
  15. Presently or previously received (within 30 days of enrollment) study drug for which an IND/IDE is in effect, with the exception of erwinia asparaginase.
  16. Pregnant or lactating female.
  17. Refusal by sexually active post-menarche female subjects to adhere to an acceptable form of contraception.
  18. Unable or unwilling to comply with scheduled follow-up visits.
  19. Inability to obtain written informed consent from subject or parent or legally acceptable representative for the subject.
