- The dose of decitabine that can be safely given with vorinostat, fludarabine, high dose cytarabine and G-CSF (FLAG) [ Time Frame: during course 1, approx 5 weeks ]The incidence of dose limiting toxicity (DLT) will be measured. The maximum tolerated dose will be the highest study dose at which 1 or fewer of six patients experience DLT during cycle 1 of therapy
- To examine peripheral blood mononuclear cells for immunophenotypic changes. [ Time Frame: approx 8 weeks ]To examine peripheral blood mononuclear cells for immunophenotypic changes using peripheral blood samples
- To analyze plasma for cytokine content. [ Time Frame: approx 8 weeks ]To analyze plasma for cytokine content using plasma samples.
- To analyze the correlation between biological changes and clinical response. [ Time Frame: approx 8 weeks ]To analyze the correlation between biological changes and clinical response using standard statistical methods
- To establish the extent of hypomethylation of peripheral blood (PB) and bone marrow (BM) pre- and post- decitabine and vorinostat treatment: [ Time Frame: approx 8 weeks ]Reduced representation bisulfite sequencing (RRBS) will be used to analyze the genome-wide methylation profiles on a single nucleotide level; To quantitatively assess global changes in DNA methylation, a LINE-methylation assay will be utilized and specific genes monitored through advanced Infinium MethylationEPIC BeadChip from Illumina. Chromatin immunoprecipitation (ChIP) with antibodies specific for histone modifications associated with transcriptional activation (H3K4me3 and H3K27ac) and repression (H3K9me3 and H3K27me3) and isotype controls, followed by DNA sequencing (ChIP-seq); RNA sequencing analysis will be used to measure global transcriptome changes. Profiles of CD33+ umbilical cord blood cells, whole bone marrow, or Peripheral Blood Stem Cells (PBSCs) will be used as normal controls for each sample.
- To analyze the correlation between DNA methylation and gene expression pre- and post-treatment with decitabine and vorinostat. [ Time Frame: approx 8 weeks ]Assessment of the in vivo effects of combined DNMTi/HDACi on the functional epigenetic profile by comparing the following in paired pre- (Day 0) and post-exposure (Day 5, Day 14 and Day 35) leukemic blasts: Reversal of DNA promoter hypermethylation of "repressed" genes of interest using RRBS, validated with Pyrosequencing-based methylation assay; Increase in H3K9/14 acetylation in association with "repressed" genes of interest using H3K9/14 ChIP-seq, validated with ChIP-qPCR; Reversal of transcriptional silencing of "repressed" genes of interest using RNA seq, validated by qRT-PCR. Since significant acute cell kill is unlikely during the 5-day "window" of DNMTi/HDACi, we will have a unique opportunity to assess the in vivo effects of epigenetic therapy with the Day 5 sample. The Day 14 peripheral blood and Day 35 marrow samples will also contribute in patients whose leukemic blasts persist at these time points.

| Ages Eligible for Study: | 1 Year to 25 Years (Child, Adult) |
| Sexes Eligible for Study: | All |
| Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- Patients must be ≥ 1 and ≤25 years of age.
Diagnosis: Patients with relapse or refractory AML must have measurable disease ( >M1 marrow)
- 1st or greater relapse, OR
- Failed to go into remission after 1st or greater relapse, OR
- Failed to go into remission from original diagnosis after 2 or more induction attempts
Eligibility for patients with an M1 marrow; defined as >0.1% by flow or molecular testing (e.g. PCR).
- must include two serial marrows (at least 1-week apart) demonstrating stable or rising minimal residual disease (MRD) (i.e. not declining).
- Patients may have CNS or other sites of extramedullary disease. No cranial irradiation is allowed during the protocol therapy.
- Patients with secondary AML are eligible.
- Patients with Down syndrome are eligible.
- Patients with DNA fragility syndromes (such as Fanconi anemia, Bloom syndrome) are excluded.
Performance Level:
- Karnofsky >50% for patients >16 years of age and Lansky > 50% for patients ≤ 16 years of age (See Appendix II for Performance Scales)
Prior therapy - Patients must have fully recovered from the acute toxic effects of all prior chemotherapy, immunotherapy, or radiotherapy prior to entering this study.
- Cytoreduction with hydroxyurea: hydroxyurea can be initiated and continued for up to 24 hours prior to the start of decitabine/vorinostat. It is recommended to use hydroxyurea in patients with significant leukocytosis (WBC >50,000/L) to control blast count before initiation of systemic protocol therapy.
- Patients who relapsed while they are receiving cytotoxic therapy: at least 14 days must have elapsed since the completion of the cytotoxic therapy, except Intrathecal chemotherapy.
Hematopoietic stem cell transplant (HSCT):
- Patients who have experienced their relapse after a HSCT are eligible, provided they have no evidence of acute or chronic Graft-versus-Host Disease (GVHD) and are off all transplant immune suppression therapy for at least 7-days (e.g. steroids, cyclosporine, tacrolimus). Steroid therapy for non-GVHD and/or non-leukemia therapy is acceptable.

For agents that have known adverse events occurring beyond 7 days after administration, this period must be extended beyond the time during which adverse events are known to occur. The duration of this interval must be discussed with the study chair.
Monoclonal antibodies: At least 3 half-lives of the antibody must have elapsed after the last dose of monoclonal antibody (i.e. Gemtuzumab = 36 days)
Immunotherapy: At least 42 days after the completion of any time of immunotherapy, e.g. tumor vaccines or CAR T-cell therapy.
