A Study of the Safety and Effectiveness of Apixaban in Preventing Blood Clots in Children With Leukemia Who Have a Central Venous Catheter and Are Treated With Asparaginase

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT02369653
Recruitment Status : Completed
First Posted : February 24, 2015
Last Update Posted : November 8, 2021

Bristol-Myers Squibb

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)

Condition or disease Intervention/treatment Phase
Lymphoma Acute Lymphoblastic Leukemia Drug: Apixaban Other: No systemic anticoagulant prophylaxis Phase 3

Masking: None (Open Label)
Primary Purpose: Prevention
Official Title: A Phase III Randomized, Open Label, Multi-center Study of the Safety and Efficacy of Apixaban for Thromboembolism Prevention Versus No Systemic Anticoagulant Prophylaxis During Induction Chemotherapy in Children With Newly Diagnosed Acute Lymphoblastic Leukemia (ALL) or Lymphoma (T or B Cell) Treated With Asparaginase
Actual Study Start Date : October 22, 2015
Actual Primary Completion Date : July 7, 2021
Actual Study Completion Date : July 7, 2021

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

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
