Phase I 5-Azacytidine Plus VPA Plus ATRA
5-aza is a chemotherapy drug with activity in leukemia and myelodysplastic syndromes (MDS). Researchers hope that valproic acid (VPA) and all-trans retinoic acid (ATRA)will increase the effects of 5-aza. The goal of this clinical research study is to find the highest safe dose of valproic acid (VPA) that can be given in combination with 5-azacytidine (5-aza) and all-trans retinoic acid (ATRA) in the treatment of AML and MDS. The safety and effectiveness of this combination therapy will also be studied.
Acute Myelogenous Leukemia
Drug: 5-Azacytidine (5-aza)
Drug: Valproic Acid
Drug: All-Trans Retinoic Acid (ATRA)
|Study Design:||Endpoint Classification: Safety/Efficacy Study
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
|Official Title:||Phase I Study of the Combination of 5-azacytidine With Valproic Acid and All-trans Retinoic Acid in Patients With High Risk Myelodysplastic Syndrome and Acute Myelogenous Leukemia|
- Maximal tolerated dose (MTD) of valproic acid (VPA) in combination with 5-azacytidine (5-aza) and all-trans retinoic acid (ATRA) [ Time Frame: 28 day cycle ] [ Designated as safety issue: Yes ]MTD defined as the dose level below where either 0 dose limiting toxicities (DLTs) out of the first 3 participants, or 1 DLT in the first 3 participants, and 0 DLTs in following additional 3 participants of a cohort. The MTD designation will apply to cycle 1 (28 day cycle). Routine blood tests (about 1-2 teaspoons each time) 2-3 times a week.

|Study Completion Date:||December 2007|
|Primary Completion Date:||July 2007 (Final data collection date for primary outcome measure)|
Experimental: VPA + 5-aza + ATRA
Daily for 7 days, Valproic acid (VPA) starting dose 75 mg/m^2 subcutaneously in combination with 5-azacytidine (5-aza) 50 mg/kg orally; and all-trans retinoic acid (ATRA) 45 mg/m^2 orally daily (in two divided doses) for 5 days starting on day 3.
Drug: 5-Azacytidine (5-aza)
Start at 75 mg/m^2 subcutaneously daily for 7 days.
Other Names:Drug: Valproic Acid
50 mg/kg daily by mouth for 7 days, same days as 5-aza.
Other Name: DepakeneDrug: All-Trans Retinoic Acid (ATRA)
45 mg/m^2 orally daily (in two divided doses) for 5 days starting on day 3 of the administration of 5-aza and VPA.
Participants receive 5-aza as an injection under the skin once a day for 7 days. This will be repeated every 3-8 weeks depending on blood counts and how well bone marrow is recovering. This is defined as 1 treatment cycle. Also during each cycle, participant will take VPA by mouth for 7 days and ATRA by mouth for 5 days. VPA will be given on the same days as 5-aza. ATRA will start on Day 3.
In the Phase I portion of the study, the dose of VPA will be increased in each new group of participants until the highest safe dose is found. A minimum of 3 participants and a maximum of 10 will be treated at each dose level.
