About
This randomized phase II trial studies how well decitabine works when given together with daunorubicin hydrochloride and cytarabine in treating patients with acute myeloid leukemia. Drugs used in chemotherapy, such as decitabine, daunorubicin hydrochloride, and cytarabine, work in different ways to stop the growth of cancer cells, either by killing the cells or by stopping them from dividing. Decitabine may help daunorubicin hydrochloride and cytarabine kill more cancer cells by making them more sensitive to the drugs. It is not yet known whether low-dose decitabine is more effective than high-dose decitabine when giving together with daunorubicin hydrochloride and cytarabine in treating acute myeloid leukemia.
Full description
OBJECTIVES: Primary I. To "Pick a Winner" by deciding whether further development of epigenetic priming with decitabine prior to standard "7+3" induction chemotherapy should be pursued.
Secondary I. To determine whether epigenetic priming with decitabine prior to standard cytarabine and daunorubicin hydrochloride "7+3" induction chemotherapy has sufficient efficacy to warrant further development as assessed by an overall CR1 rate ≥ 50%.
II. To establish the safety and expected toxicities of decitabine when used as priming for cytarabine and daunorubicin hydrochloride "7+3" induction chemotherapy in acute myeloid leukemia (AML).
III. To assess the pharmacodynamics of deoxyribonucleic acid (DNA) hypomethylation when decitabine is administered as a short infusion.
IV. To investigate, in selected cases, the molecular and cellular consequences of decitabine-induced hypomethylation by assessing the effects of decitabine-mediated hypomethylation on transcriptional patterns in AML cells, and by determining the effect of hypomethylation on the differentiation and/or apoptosis of leukemic blasts. (exploratory) V. To identify biomolecular correlates of treatment response (biomarkers) to induction chemotherapy in AML based upon the epigenetic pattern of DNA methylation in AML specimens obtained prior to treatment. (exploratory)
OUTLINE: This is a multicenter study. Patients are stratified according to age (less than 50 years vs 50-65 years), white blood cell count (≤ 30 K/mL vs greater than 30 K/mL), cytogenetic risk group (intermediate vs adverse risk), and antecedent hematological condition preceding the diagnosis of acute myeloid leukemia (yes vs no). Patients are randomized to 1 of 2 treatment arms.
Arm I: Patients receive induction chemotherapy comprising daunorubicin hydrochloride intravenously (IV) daily on days 1-3 and cytarabine IV continuously on days 1-7 in the absence of disease progression or unacceptable toxicity. Patients who do not achieve a complete remission (CR) after the first induction-chemotherapy course receive a second identical induction course.
Arm II: Patients receive decitabine IV over 1 hour on days -5 to -1. Patients then receive induction chemotherapy as in arm I in the absence of disease progression or unacceptable toxicity. Patients who do not achieve a CR after the first induction-chemotherapy course receive a second identical induction course.
Patients undergo blood, bone marrow, and oral mucosa cells sample collection at baseline, prior to induction therapy, and after treatment for DNA methylation studies and pharmacodynamic studies.
After completion of study treatment, patients are followed up for up to 10 years.

-
Eastern Cooperative Oncology Group (ECOG) performance status ≤ 2 (Karnofsky ≥ 60%)
-
Adequate cardiac function as defined by either of the following:
- An echocardiogram demonstrating an ejection fraction within normal limits
- A multi gated acquisition (MUGA) scan demonstrating an ejection fraction within normal limits
-
Aspartate aminotransferase (AST)(serum glutamic oxaloacetic transaminase [SGOT])/alanine aminotransferase (ALT)(serum glutamate pyruvate transaminase [SGPT]) ≤ 2.5 times institutional upper limit of normal (ULN)
-
Creatinine ≤ 2 mg/dL OR creatinine clearance ≥ 50 mL/min
-
Total bilirubin ≤ 2 times ULN
- Patients with documented diagnosis of Gilbert syndrome resulting in elevated total bilirubin levels will be eligible, provided all other eligibility criteria are met
- Patients with a total bilirubin of 2-3 mg/dL and direct (conjugated) bilirubin in the normal range will be eligible, provided all other eligibility criteria are met
-
Pregnant and nursing subjects may not be enrolled and pregnancy must be avoided; women of child-bearing potential-defined as a sexually active woman who has not undergone hysterectomy and who has had menses any time within the preceding 24 months-must have a negative serum or urine pregnancy test within 7 days prior to registration; women and men of childbearing potential must either commit to continued abstinence from heterosexual intercourse or commit to two acceptable methods of birth control-one highly effective method (e.g., IUD, oral or non-oral hormonal contraceptive, tubal ligation or partner's vasectomy) and one additional effective method (e.g., latex condom, diaphragm or cervical cap) at the same time from the time of screening through final Treatment Response Assessment
- NOTE: should a woman become pregnant or suspect she is pregnant while she or her partner is participating in this study, the subject should inform their treating phy-sician immediately
- NOTE: the effects of decitabine on the developing human fetus are unknown but it is a know teratogen in mammals (mice)
-
Ability to understand and the willingness to sign a written informed consent document
Exclusion criteria
-
Chemotherapy (other than hydroxyurea) or radiation within the 2 weeks prior to planned therapy on this study or ongoing adverse events due to agents administered more than 2 weeks earlier
-
Concurrent treatment with other investigational agents is not permitted
-
Cumulative lifetime dose of anthracycline chemotherapeutic > 80 mg/m^2
-
History of allergic reactions attributed to compounds of similar chemical or biologic composition of decitabine, cytarabine or daunorubicin
-
Uncontrolled intercurrent illness considered by the investigator to constitute an unwarranted high risk for investigational drug treatment; examples include, but not limited to the following:
- Uncontrolled serious infection; or
- Unstable angina pectoris; or
- Uncontrolled cardiac arrhythmia; or
- Active second malignancy requiring treatment; or
- Symptomatic congestive heart failure
-
HIV-positive subjects with a CD4 count < 200 cells/μL are excluded due to the increased risk of lethal infections when treated with marrow-suppressive chemotherapy(87)
- NOTE: subjects with HIV infection and a CD4 count >= 200 cells/μL are eligible but combination antiretroviral therapy should be held during administration of chemotherapy due to the potential for pharmacokinetic interactions with decita-bine, cytarabine or daunorubicin. Antiretroviral therapy may be resumed 24 hours after completion of the last dose of induction chemotherapy
-
Subject has a psychiatric disorder, altered mental status or social situation that would preclude understanding of the informed consent process and/or limit compliance with study requirements
