Bisantrene combined with Fludarabine and ClofarabineBisantreneBisantrene 250 mg at final concentration of 0.5 mg/mL will be administrated by intravenous (IV) infusion, delivered by a controlled-rate programmable pump via a central line over 2 hours. Fludarabine (generic) and Clofarabine (generic) are commercially available as injection for intravenous infusion. The treatment regimen will comprise daily IV infusion of Fludarabine (Flu), Clofarabine (Clo) and Bisantrene (Xan) administered via central venous line and controlled-rate infusion pump with a 1-hour break between each agent infusion, amounting to a total of 6 hours for each daily FluCloXan treatment in the following sequence: * First, infusion over 60 minutes of Fludarabine (Flu) at 10 mg/m2 * Followed by infusion of Clofarabine (Clo) at 30 mg/m2 over 60 minutes * Followed by infusion of Bisantrene (Xan) at 250 mg/m2 over 2 hours.
