Brief Summary:
This is a pilot study using decitabine and vorinostat before and during chemotherapy with vincristine, dexamethasone, mitoxantrone, and peg-asparaginase in pediatric patients with acute lymphoblastic leukemia (ALL).

Condition or disease Intervention/treatment Phase
Acute Lymphoblastic Leukemia Precursor B-Cell Lymphoblastic Leukemia Precursor T-Cell Lymphoblastic Leukemia Drug: Decitabine Drug: Vorinostat Drug: Vincristine Drug: Dexamethasone Drug: Mitoxantrone Drug: Pegaspargase Drug: Methotrexate Phase 1 Phase 2

Detailed Description:
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 lymphoblastic leukemia.

Primary Outcome Measures :
  1. Number of participants with adverse events. [ Time Frame: 6 weeks ]
    To evaluate the side effects of giving decitabine and vorinostat before and during chemotherapy using the standard drugs vincristine, dexamethasone, PEG-asparaginase and mitoxantrone.

Secondary Outcome Measures :
  1. Disease response rate after treatment. [ Time Frame: 6 weeks ]
    The study will assess whether the patient's acute lymphoblastic leukemia goes into remission after treatment.

  2. Gene-specific methylation profiles [ Time Frame: 2 years ]
    To assess the biologic activity of decitabine by comparing pre and post-treatment marrow samples for global and gene-specific methylation profiles using HELP and methylation-specific PCR.

  3. Global histone acetylation and histone modifications [ Time Frame: 2 years ]
    To assess the biological activity of vorinostat by comparing pre- and post-treatment blood and bone marrow samples for global histone acetylation (using acetyl-H3 Western blotting), and for gene-specific histone modifications (using H3K9/14Ac ChIP-chip and ChIP-qPCR).

  4. Gene expression profiles [ Time Frame: 2 years ]
    To determine the impact of combined epigenetic therapy on the expression of epigenetically-regulated genes by comparing pre and post-treatment marrow samples for gene expression profiles (using microarrays), and correlating these with the methylation and histone modification assays.
