Brief Summary:
The purpose of this study is to compare the effect of a blood thinning drug called Apixaban versus no administration of a blood thinning drug, in preventing blood clots in children with leukemia or lymphoma. Patients must be receiving chemotherapy, including asparaginase, and have a central line (a catheter inserted for administration of medications and blood sampling)

Arm Intervention/treatment
Experimental: Apixaban

Children aged 1 to <18 years weighing 6 to <35 kg randomized to apixaban will receive a fixed dose apixaban based on body weight tier twice a day for approximately 28 days.

Children aged 1 to <18 years weighing ≥ 35 kg will receive 2.5 mg of apixaban twice a day for approximately 28 days. Subjects ≥ 5 years may be administered either 2.5-mg, 0.5-mg tablets or oral solution apixaban. Subjects < 5years and < 35 kg may be administered 0.5-mg tablets only

 Drug: Apixaban
Placebo Comparator: No systemic anticoagulant prophylaxis
No systemic anticoagulant prophylaxis
 Other: No systemic anticoagulant prophylaxis


Outcome Measures
Go to 
Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Efficacy: A composite of adjudicated non-fatal deep vein thrombosis (DVT, including asymptomatic and symptomatic), pulmonary embolism (PE), and cerebral venous sinus thrombosis (CSVT) and venous thromboembolism (VTE)-related-death [ Time Frame: Up to 1 month ]
    Objectively confirmed by independent adjudication

  2. Safety: Adjudicated major bleeding using the International Society on Thrombosis and Haemostasis (ISTH) definition for children [ Time Frame: Up to 1 month ]

Secondary Outcome Measures :
  1. Efficacy: a) Non-fatal asymptomatic DVT [ Time Frame: Up to 1 month ]
  2. Efficacy: b) Non-fatal symptomatic DVT [ Time Frame: Up to 1 month ]
  3. Efficacy: c) Non-fatal PE [ Time Frame: Up to 1 month ]
  4. Efficacy: d) CSVT [ Time Frame: Up to 1 month ]
  5. Efficacy: e) VTE-related-death [ Time Frame: Up to 1 month ]
  6. Safety: Composite of major and clinically relevant non major bleeding (CRNMB) using the ISTH definition for children [ Time Frame: Up to 1 month ]
  7. Pharmacodynamics: Anti-FXa Activity measured by plasma concentration assay [ Time Frame: Up to 1 month ]
  8. Pharmacokinetics: Measured by maximum observed concentration (Cmax) [ Time Frame: Up to 1 month ]
  9. Pharmacokinetics: Measured by trough observed concentration (Cmin) [ Time Frame: Up to 1 month ]
  10. Pharmacokinetics: Measured by area under the concentration-time curve in one dosing interval [AUC(TAU)] [ Time Frame: Up to 1 month ]

Inclusion Criteria:

  • New diagnosis of de novo ALL, lymphomas (T or B cell), or mixed-phenotype acute leukemia
  • Planned 3-4 drug systemic induction chemotherapy with a corticosteroid, vincristine and a single dose or multiple doses of asparaginase, with or without daunorubicin
  • Functioning Central Venous Access Device
  • Must be able to tolerate oral medication or have it administered via an Nasogastric tube (NGT) or GT tube
  • Males and females,age 1 year(365 days) to < 18 (17 years and 364 days) years.

Exclusion Criteria:

  • Subjects scheduled to have > 3 Lumbar Punctures over the course of the study treatment period
  • Prior history of documented DVT or PE in the past 3 months
  • Known inherited bleeding disorder or coagulopathy
  • Major surgery [excluding Central Venous Access Device (CVAD) replacement and bone marrow aspiration and non-open biopsy] within the last 7 days prior to enrollment that may be associated with a risk of bleeding. Open biopsy is considered a major surgery.
  • Uncontrolled severe hypertension at enrollment. Severe hypertension is defined as a systolic or diastolic blood pressure (BP) > 5 mm Hg above the 95th percentile as defined by the National High Blood Pressure Education Program Working Group (NHBPEP) established guidelines for the definition of normal and elevated blood pressure in children
  • Extreme hyperleukocytosis, white blood cell (WBC) counts over 200 x 109/L (200,000/microL) at the time of enrollment
  • Liver dysfunction manifested by SGTP (ALT) > 5X Upper limit of normal (ULN) and/or Aspartate aminotransferase (AST) >5 X ULN and/or direct (conjugated) bilirubin > 2X ULN
  • Renal function < 30% of normal for age and size as determined by the Schwartz formula
  • International normalized ratio (INR) > 1.4 and activated partial thromboplastin time (aPTT) > 3 seconds above the upper limit of normal for age, within 1 week prior to enrollment.
  • History of allergy to apixaban or Factor Xa inhibitors
  • History of significant adverse reaction or major bleeding related adverse reaction to other anticoagulant or antiplatelet agents
  • History of any significant drug allergy (such as anaphylaxis or hepatotoxicity
  • Any investigational drug being administered during the study

Other protocol inclusion/exclusion criteria may apply
