Description of intervention(s) / exposure
Treatment: Drugs - Apixaban
Treatment: Drugs - Standard of Care

Experimental: Apixaban - Subjects between birth to \<18 years will be dosed on a body weight tiered regimen. Subjects =35kg will receive 10mg twice daily(BID) for 7 days followed by 5mg BID thereafter;\<35kg to 25kg will receive 8mg BID for 7 days followed by 4mg BID thereafter;\<25 to 18kg will receive 6mg BID for 7 days and then 3mg BID thereafter;\<18 to 12kg will receive 4mg BID for 7 days and then 2mg BID thereafter;\<12 to 9kg will receive 3mg BID for 7 days and then 1.5mg BID thereafter;\< 9kg to 6kg will receive 2 mg BID for 7 days and 1mg BID thereafter;\<6kg to 5kg will receive 1mg BID for 7 days and 0.5mg BID thereafter;\<5kg to 4kg will receive 0.6mg twice daily for 7 days and 0.3mg BID thereafter;PK cohort neonates = 2.6kg will receive 0.1mg BID. Dose will be adjusted as determined by PK measurements (ie, to 0.2mg BID, 0.1mg daily or dose will stay the same).For the post PK cohort Neonates ?4kg to 2.6kg, if confirmed by PK sub analysis,subjects will receive 0.2mg BID for 7 days and 0.1mg BID thereafter.
