Study Arms:
- Treatment (chemotherapy) (Type: EXPERIMENTAL): Patients receive clofarabine PO QD on days 1-5 and low-dose cytarabine SC BID on days 1-10 or SC QD on days 1-14. Treatment repeats every 21-28 days for up to 4 courses in the absence of disease progression or unacceptable toxicity.

Based on this trial design, predict the completion outcome and termination type (if applicable).
