Phase II Study of Clofarabine in Adult Patients With Refractory or Relapsed Acute Myelogenous Leukemia

Study Overview
=================
Brief Summary
-----------------
Clofarabine (injection) is approved by the Food and Drug Administration (FDA) for the treatment of pediatric patients 1 to 21 years old with relapsed acute lymphoblastic leukemia (ALL) who have had at least 2 prior treatment regimens. This is a single arm, open-label, Phase II study of CLOFARABINE in adult patients with refractory or relapsed acute myelogenous leukemia (AML). Qualified patients must be refractory to one or two induction regimens, or have relapsed < one year from the date of confirmation of the initial complete remission (CR). There will be two phases in this study - an Induction phase and a Consolidation phase.
