研究概览
简要总结
The goal of this clinical research study is to compare how well 2 different dosing schedules of decitabine may help control AML.
Decitabine is designed to damage the DNA (the genetic material) of cells, which may cause cancer cells to die.
详细描述
Study Groups:
If you are found to be eligible to take part in this study, you will be assigned to 1 of 2 dose levels of decitabine based on when you join this study. If you are among the first 20 participants, you will have an equal chance of being in either group. If you enroll after that, you will have an increasingly higher chance (51-100%) of being assigned to the group that had better results, depending on how much better that treatment arm is.
Study Drug Administration:
Each cycle is about 4-8 weeks, depending on the doctor's decision. In this study you will receive induction therapy to try to control the disease and cause remission (this is when tests and/or the doctor cannot find signs of the disease).
If you are in Group 1, you will receive decitabine by vein over about 1 hour for 5 days.

入选标准
- •Patients with previously untreated AML (by the World Health Organization (WHO) criteria, i.e. >/= 20% blasts) Prior biologic therapies (such as growth factors) and targeted therapies administered for the treatment of prior myelodysplastic syndrome are allowed, with the exception of hypomethylating agents 5-azacytidine or decitabine. Patients must have been off such therapy for 1 week prior to entering this study and recovered from the toxic effects of that therapy, unless there is evidence of rapidly progressive disease. Hydroxyurea, and a single dose of cytarabine up to 3 g/m2, is permitted for control of counts prior to treatment.
- •Patients >/= 60 are eligible if not a candidate for standard cytarabine plus anthracycline chemotherapy as determined by Kantarjian's score (Appendix D) Patients younger than 60 may also be included if felt not to be a candidate for intensive anthracycline plus cytarabine based chemotherapy.
- •Performance 0-3 (ECOG).
- •Adequate liver function (Total bilirubin of < 2 mg/dl) unless due to hemolysis, leukemia organ infiltration or Gilbert's syndrome and renal function (creatinine < 2.5 mg/dl).
- •Signed informed consent
排除标准
- •Nursing and pregnant females. Female patients of childbearing potential and male patients should practice effective methods of contraception such as double barrier method. Should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately. Negative urine pregnancy test (women of childbearing potential)
- •Active and uncontrolled infections.
- •Uncontrolled intercurrent illness including, but not limited to, symptomatic congestive heart failure, unstable angina pectoris, active significant other cancers requiring chemotherapy and/or radiation therapy within past 6 months (excluding non-melanoma skin cancer) or psychiatric illness/social situations that would limit compliance with study requirements.

结局指标
主要结局
Participants With a Response
时间窗: Up to 3 months
Response is defined as Complete Response (CR) + Partial Remission (PR) + Complete Remission with incomplete recovery (CRi) + Clinical Benefit. CR is the normalization of the peripheral blood and bone marrow with \</= 5% bone marrow blasts, a peripheral blood granulocyte count \>/= (1.0 x 10\^9/L, and a platelet count \>/= 100 x 10\^9/L). PR is the same as CR except for the presence of 6-15% marrow blasts, or 50% reduction if \<15% at start of treatment. CRi meets all criteria for CR except for platelet recovery to \>100 x 10\^9/L and/or granulocyte count \> (1.0 x 10\^9/L). Clinical benefit is platelets increase by 50% and to above 30 x 10\^9/L untransfused (if lower than that pretherapy); or granulocytes increase by 100% and to above 10\^9/L (if lower than that pre-therapy); or hemoglobin increase by 2 g/dl; or transfusion independent; or splenomegaly reduction by \> 50%; or monocytosis reduction by \> 50% if pretreatment \> 5 x 109/L.
次要结局
- Overall Survival(Up to 5 years)
- Response Duration(Up to 5 years)
