Development of personalized molecular therapy for acute myeloid leukemia

Acute myeloid leukemia (AML) is characterized by extensive clinical and biological heterogeneity.
Despite vast advances in understanding the molecular pathology in AML during the last
two decades few new AML therapeutics have been approved by the European Medicines Agency.
Since 2005 only the epigenetic modulators decitabine and azacytidine, as well as histamine (plus interleukin-
2) have been approved against AML. None of these have outstanding efficiency, and decitabine
and azacytdine have only been incorporated in frontline therapy of AML with limited enthusiasm. The majority of AML
patients are frail and elderly, and lack of mild but effective agents for this patient cohort constitutes a major unmet need as
overall survival remains poor. Along with the recent advancements in the molecular characterization of AML, numerous
targeted therapies have been tested in clinical trials. In this review, we discuss the biological rationale for a selection of
these novel therapeutic approaches, including epigenetic modifiers, agents targeting signalling pathways and inhibitors of
nuclear-cytoplasmic shuttling. Further we discuss some of the possible shortcomings in current trial design that could explain
the apparent incoherence between our improved biological knowledge and the lack of progress in therapy development
