The Role of Maintenance Oral Clofarabine in Older Adults With Acute Myeloid Leukemia
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.

|Official Title:||A Phase I Feasibility Study Assessing the Role of Maintenance Oral Clofarabine in Older Adults With Acute Myeloid Leukemia|
- Determine the maximum tolerated dose of oral clofarabine. [ Time Frame: at study completion (estimated at 2 years) ] [ Designated as safety issue: Yes ]
- Measure the relapse-free survival. [ Time Frame: labs drawn weekly (first cycle) and every other week thereafter until progression ] [ Designated as safety issue: No ]
|Study Start Date:||June 2011|
dose escalation, administered orally, once a day for 21 days per cycle (cycles begin every 28-49 days)
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.
