CRNM bleeding is defined as bleeding that satisfies one or both of the following:
- overt bleeding for which blood product is administered and not directly attributable to the subject's underlying medical condition and
- bleeding that requires medical or surgical intervention to restore hemostasis, other than in an operating room
- The Number of Participant Deaths [ Time Frame: From first dose date until the end of the treatment period + 30 days (Up to approximately 59 days) ]The number of participant deaths adjudicated by a blinded, independent adjudication committee

- The Number of Participants Needing Catheter Replacements During the Study [ Time Frame: From first dose up to approximately 34 days after first dose ]The number of participants needing catheter replacements during the study
- The Number of Participants With CVAD Patency Restoration Events After Thrombolytic Therapy Use [ Time Frame: From first dose up to approximately 34 days after first dose ]The number of participants with central venous access device (CVAD) patency restoration events after thrombolytic therapy use
- The Number Participants Experiencing Superficial Vein Thrombosis Events [ Time Frame: From first dose up to approximately 34 days after first dose ]
The number participants experiencing superficial vein thrombosis events.
Clots that occur in a superficial vein ie, cephalic vein, basilic vein (upper extremity) or saphenous vein (lower extremity) confirmed by radiographic imaging.
- The Number of Participants With Clinically Relevant Non-Major Bleeding Events (CRNMB) [ Time Frame: From first dose up to approximately 34 days after first dose ]
The number of participants with clinically relevant non-major bleeding events (CRNMB) adjudicated by a blinded, independent adjudication committee.
CRNM bleeding is defined as bleeding that satisfies one or both of the following:
- overt bleeding for which blood product is administered and not directly attributable to the subject's underlying medical condition and
- bleeding that requires medical or surgical intervention to restore hemostasis, other than in an operating room
- The Number of Participants With Minor Bleeding Events [ Time Frame: From first dose up to approximately 34 days after first dose ]
The number of participants with minor bleeding events adjudicated by a blinded, independent adjudication committee.
Minor bleeding defined as any overt or macroscopic evidence of bleeding that does not fulfill the criteria for either major bleeding or CRNMB
- The Number of Platelet Transfusions Needed During the Study [ Time Frame: From first dose up to approximately 34 days after first dose ]
The number of platelet transfusions needed during the study.
The events are not adjudicated. A subject could have more than one platelet transfusion.
- Maximum Observed Concentration (Cmax) [ Time Frame: pre-dose, 1-4 hours post dose ]The maximum observed concentration (Cmax) was measured to assess the pharmacokinetics of oral or enteric apixaban in pediatric subjects receiving induction chemotherapy.
- Trough Observed Concentration (Cmin) [ Time Frame: pre-dose, 1-4 hours post dose ]The trough observed concentration (Cmin) was measured to assess the pharmacokinetics of oral or enteric apixaban in pediatric subjects receiving induction chemotherapy.
- Area Under the Concentration-Time Curve [AUC(TAU)] [ Time Frame: pre-dose, 1-4 hours post dose ]The area under the concentration-time curve [AUC(TAU)] was measured to assess the pharmacokinetics of oral or enteric apixaban in pediatric subjects receiving induction chemotherapy.
- Anti-FXa Activity [ Time Frame: pre-dose and 2.5 hours after dosing on day 7. Day 8 and day 15. ]Anti-FXa Activity was measured to characterize the relationship between apixaban plasma concentration and anti-FXa activity in pediatric subjects receiving induction chemotherapy
