MTD and dose-limiting toxicity (DLT) of the new 10-day schedule of FdCyd/THU [ Time Frame: 10 days ] [ Designated as safety issue: Yes ]
Toxicities will be summarized by Common Terminology Criteria for Adverse Events (CTCAE) grade and attribution using the version current at the initiation of the protocol.
  • Select the best dose based on the response rate of FdCyd (40 mg/m2/day or 80 mg/m2/day) separately in previously treated and untreated patients. [ Time Frame: 3 years ] [ Designated as safety issue: No ]
  • Determine the response rate (CR + PR) of FdCyd at each of two doses (40 mg/m2 and 80 mg/m2) administered 5 days per week on days 1-5 and 15-19, in 28-day cycles, by IV infusion over 3 hours along with THU in patients with AML and MDS. [ Time Frame: 3 years ] [ Designated as safety issue: No ]

5-Fluoro-2'-Deoxycytidine and Tetrahydrouridine in Treating Patients With Acute Myeloid Leukemia or Myelodysplastic Syndromes
A Phase I Study of 5-Fluoro-2'-Deoxycytidine With Tetrahydrouridine (FdCyd + THU) in Myeloid Leukemia and MDS

This phase I trial is studying the side effects and best dose of 5-Fluoro-2'-deoxycytidine (FdCyd) when given together with tetrahydrouridine (THU) in treating patients with acute myeloid leukemia (AML) or myelodysplastic syndromes (MDS). FdCyd may inhibit cancer cell growth by increasing the production in cells of compounds that suppress growth or by otherwise killing cells. Although FdCyd is stable as a drug solution, it is rapidly inactivated by an enzyme present in people. THU is included in the treatment to inhibit the enzyme, prolonging the time FdCyd remains in the body

OBJECTIVES: I. Determine the maximum tolerated dose (MTD) of FdCyd administered with a fixed dose of THU in patients with acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS), once daily on days 1-10 of a 21-day treatment cycle. II. To describe the toxicities of FdCyd/THU in patients with acute myelogenous leukemia (AML) and myelodysplastic syndrome (MDS). III. To document all clinical responses and hematologic improvement in patients treated with FdCyd/THU. IV. To obtain preliminary information regarding the effect of FdCyd/THU on deoxyribonucleic acid (DNA) methylation patterns in peripheral blood mononuclear cells and bone marrow aspirates, including malignant myeloid cells; the ratio of gamma- to beta-globin messenger ribonucleic acid (mRNA) in blood cells; and serum cytokines. OUTLINE: This is a dose-escalation study of FdCyd. Patients receive FdCyd intravenously (IV) over 3 hours and THU IV over 3 hours on days 1-10. Courses repeat every 21days in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up for 4 weeks.

  • Ability to understand and the willingness to sign a written informed consent document
  • Patients should not be receiving any other investigational agents

Exclusion Criteria:

  • Patients with clinically significant illnesses which would compromise participation in the study, including, but not limited to: active or uncontrolled infection, immune deficiencies or confirmed diagnosis of human immunodeficiency virus (HIV) infection, active Hepatitis B, active Hepatitis C, or uncontrolled diabetes, uncontrolled hypertension, symptomatic congestive heart failure, unstable angina pectoris, myocardial infarction within the past 6 months, uncontrolled cardiac arrhythmia; or psychiatric illness/social situations that would limit compliance with study requirements
  • Patients with additional (other than AML/MDS) currently active primary malignancy other than curatively treated carcinoma in situ (CIS) of the cervix, or basal or squamous cell carcinoma of the skin; patients are not considered to have a "currently active" malignancy if they have completed therapy for a prior malignancy and disease free from prior malignancies for > 2 years
