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
Purpose
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)

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 |
