Clofarabine Plus Low-Dose Cytarabine for Patients With Higher-Risk Myelodysplastic Syndrome (MDS)
The goal of this clinical research study is to learn if clofarabine when given in combination with cytarabine can help to control myelodysplastic syndrome (MDS) after the disease could not be controlled with standard therapy. The safety of this treatment will also be studied.
Clofarabine is designed to interfere with the growth and development of cancer cells.
Cytarabine is designed to insert itself into DNA (the genetic material of cells) of cancer cells and stop the DNA from repairing itself.

- Number of Participants with Complete Response (CR) [ Time Frame: 4 weeks after first cycle ]Complete Response Criteria (CR must last for at least 4 weeks): Marrow: </= 5% myeloblasts with normal maturation of all cell lines; Persistent dysplasia noted; Blood: Hemoglobin (Hb) >/= 11 g/dL (untransfused, patient not on EPO); Neutrophils >/= 1x109/L (not on myeloid growth factor); Platelets >/= 100 * 109/L (not on thrombopoietic agent); No blasts. Bone marrow aspirate and/or biopsy at the end of course 1 (day 28 +/- 7 days). The method of Thall, Simon, and Estey used to monitor response.
- Overall Survival (OS) [ Time Frame: 6 months ]Overall survival defined as the time interval from study entry date to the date of death due to any cause, measured in days/months. Bayesian time-to-event model used to monitor overall survival.
