Clinical Trial Summary

FLAT-Auto is a phase II trial. fludarabine and ARA-C will be combined with the alkylating agent treosulfan (FLAT), to investigate the feasibility and the efficacy of a new regimen, supported with autologous peripheral blood SCT (PBSCT), as final postremission consolidation in AML/MDS elderly patients.
