Brief summary: The purpose of this study is to determine the side effects of the study drug, clofarabine, when given by mouth to patients with acute myeloid leukemia (AML), in remission.

Detailed description: Standard induction chemotherapy (chemotherapy given with the intent of inducing a remission/disappearance of the cancer) can lead to a complete remission (CR) in a large percentage (60% to 80%) of younger patients with newly diagnosed AML. However, the majority of patients relapse (their disease returns) despite intensive consolidation chemotherapy. In most chemotherapy studies, only a small percentage (30% to 40%) of patients who achieve a CR still are disease-free 5 years later. The outcome for older adults is even less favorable. Approximately 75% of elderly patients who achieve CR will relapse after 2 years or less and the toxicities seen with treatment are significant. A number of studies have shown that chemotherapy given to older adults after a remission has not improved this outcome; therefore new treatments need to be investigated. Clofarabine is a drug that has been studied in older adults who have achieved a CR. The treatment was found to have fewer side effects then other consolidation therapies. This study will give participants the drug for a longer period of time to see if doing this will extend the cancer remission. Clofarabine has been approved by the FDA for the treatment of acute lymphoblastic leukemia (ALL), another form of acute leukemia. The study drug is considered experimental for AML because it has not been approved by the Food and Drug Administration (FDA) for the treatment of AML.

Eligibility criteria: Inclusion Criteria:

* Diagnosis of acute myeloid leukemia, in first or second remission.
* Age 55 or older
* Patients must have given signed, informed consent prior to registration on study.
* Participants must have attained a complete remission (CR) to induction chemotherapy and are not good candidates for further intensive chemotherapy or a transplant.
* Female patients of childbearing potential must have a negative serum pregnancy test within 2 weeks prior to enrollment.
* Male and female patients must use an effective contraceptive method during the study and for a minimum of 6 months after study treatment.

Exclusion Criteria:

* Patients with a diagnosis of acute promyelocytic leukemia are not eligible.
* Participants cannot be currently receiving chemotherapy, radiation therapy, or immunotherapy.
* Patients must not be receiving any other investigational agents.
* Participants cannot have Hepatitis B or C or HIV.
* Patients must not have an uncontrolled infection
