Study of Decitabine Induction Prior to Allogeneic Hematopoietic Cell Transplant in Newly Diagnosed MDS Patients

Summary

Allogeneic blood stem cell transplant remains the only potential curative treatment for myelodysplastic syndromes (MDS) to date. Pre-transplant induction chemotherapy with leukemia-type regimens is associated with significant toxicity and even death. The hypomethylating agents decitabine and 5-azacytidine have been shown in studies to cause improved hematologic parameters and partial or complete responses in patients with high risk MDS compared to standard therapy. In contrast to leukemia-type chemotherapy, decitabine is associated with a relatively low risk of toxicity. We therefore propose to treat transplant-eligible MDS patients with Decitabine as induction therapy and a bridge to transplant. Hypothesis: 1. Decitabine is able to reduce disease burden as measured by blood and marrow blast counts prior to allogeneic hematopoietic stem cell transplant to below 5%. 2. Decitabine is well-tolerated by patients with high-risk MDS and will be a safe induction agent and bridge prior to allogeneic transplant in transplant-eligible patients.
