Brief summary

The purpose of this study is to examine the feasibility and efficacy of using the demethylating agent 5-Azacytidine prior to allogeneic stem cell transplantation in patients with high risk myelodysplastic syndrome (MDS).

Detailed description

The study drug, 5-azacytidine, is given daily intravenously for 7 days. After every 2 cycles study participants will have a bone marrow test to evaluate the effect of the 5-azacytidine on the Myelodysplastic Syndrome (MDS). Participants continue to get cycles of 5-Azacytidine until 2 bone marrow tests show the MDS has stopped responding to the treatment. At that time they will undergo a transplant if a donor is available.

Interventions

The recommended starting dose for the first treatment cycle, for all patients regardless of baseline hematology laboratory values, is 75 mg/m2 subcutaneously or intravenously, daily for 7 days.

Negative serum pregnancy test prior to 5-Azacytidine treatment for women of childbearing potential 8. Women and men of childbearing potential agree to use contraception while receiving treatment with 5-Azacytidine 9. Potentially eligible for allogeneic transplantation 10. No prior allogeneic transplant 11. Age 18 to 70, inclusive.

Exclusion criteria

1. Known or suspected hypersensitivity to 5-azacytidine or mannitol 2. Patients previously treated with 5-azacytidine or deoxyazacytidine 3. Pregnant or breast feeding 4. Patients with advanced malignant hepatic tumors

Outcome results

Primary

One Year Event Free Survival (EFS) for Allogeneic Transplant Recipients After Transplantation

Percentage of participants that received allogeneic transplant and had event free survival, as estimated by the Kaplan-Meier survival curve. The events analyzed are evidence of molecular, cytogenetic or histologic relapse or death from any cause. The estimated one-year event-free survival rate is the same as overall survival, 50%.

Time frame: 1 year

Population: Patients surviving after stem cell infusion will be considered in the transplantation cohort; those dying or relapsing prior to this event are considered to have progressed. Outcomes of 5-Axacytidine responders and non-responders will be compared. Patients alive at the time of last observation will be censored.
