The combination of a DNA hypomethylating agent with a histone deacetylase inhibitor has synergistic antileukemia activity and may restore sensitivity to all-trans retinoic acid (ATRA). We conducted a phase 1/2 study of the combination of 5-azacitidine (5-AZA), valproic acid (VPA), and ATRA in patients with acute myeloid leukemia or high-risk myelodysplastic(More)

We conducted a prospective randomized phase II study to evaluate two chemotherapy regimens: (i) rituximab plus hyperfractionated cyclophosphamide, vincristine, doxorubicin and dexamethasone (R-HCVAD) alternating with rituximab, high-dose methotrexate, and cytarabine (R-MA) and (ii) rituximab, cyclophosphamide, doxorubicin, vincristine and prednisone(More)
BACKGROUND Despite advances in therapy, the majority of adult patients diagnosed with acute myeloid leukemia (AML) develop disease recurrence and die of their disease. Early intensification of treatment for AML using timed sequential therapy (TST) has been proposed as a means of improving the survival outcome in children. The Children's Cancer Group(More)
6563 Background: The combination of a hypomethylating agent with a histone deacetylase inhibitor (HDACI) has synergistic activity. The combination of ATRA with either a hypomethylating agent or a HDACI restores ATRA sensitivity in resistant cells. The combination of VPA and ATRA has activity in patients with MDS. Based on this, we developed a phase I/II(More)
