Epigenetic Reprogramming in Relapse/Refractory AML

Official Title

Epigenetic Reprogramming in Relapse AML: A Phase 1 Study of Decitabine and Vorinostat Followed by Fludarabine, Cytarabine and G-CSF (FLAG) in Children and Young Adults With Relapsed/Refractory AML


This is a pilot study using decitabine and vorinostat before and during chemotherapy with fludarabine, cytarabine and G-CSF (FLAG).

Trial Description

Primary Outcome:

  • The dose of decitabine that can be safely given with vorinostat, fludarabine, high dose cytarabine and G-CSF (FLAG)
Secondary Outcome:
  • To examine peripheral blood mononuclear cells for immunophenotypic changes.
  • To analyze plasma for cytokine content.
  • To analyze the correlation between biological changes and clinical response.
  • To establish the extent of hypomethylation of peripheral blood (PB) and bone marrow (BM) pre- and post- decitabine and vorinostat treatment:
  • To analyze the correlation between DNA methylation and gene expression pre- and post-treatment with decitabine and vorinostat.
Decitabine is a demethylating agent and vorinostat is a HDAC inhibitor. The use of demethylating agents and HDAC inhibitors in combination have been previously shown to have synergistic effects in altering neoplastic pathways of cancer cells and be well tolerated in human clinical studies. With the ability of decitabine and vorinostat to alter the abnormal cellular pathways of leukemic blasts and essentially turn off anti-apoptotic proteins, the leukemia cells have become primed for cytotoxic cell kill via chemotherapeutic agents. This study will ask the question as to whether or not the combination of decitabine and vorinostat followed by chemotherapy is feasible and whether it can positively impact outcome in patients with relapsed or refractory acute myelogenous leukemia.
