Chidamide Plus DCAG for Relapsed/Refractory AML

Study Overview
=================
Brief Summary
-----------------
Despite advances in understanding the complexities of acute myeloid leukaemia (AML), the treatment of refractory or relapsed AML (rrAML) remains a daunting clinical challenge.The investigators designed a new regimen, including chidamide, decitabine, aclarubincin, cytarabine and G-CSF, to treat rrAML.
