Chemotherapy Followed Cord Blood Infusion for Patients with AML (FHCRC-2335)
Clofarabine in Combination with Cytarabine (Ara-C) and G-CSF Priming Followed by Infusion of Ex Vivo Expanded Cord Blood Progenitors for Patients with AML
Status Conditions Phase Study ID
Closed Acute Myeloid Leukemia (AML); Hematologic Malignancies; Leukemia Phase I FHCRC-2335

The purpose of this research study is to determine the safety and efficacy of an experimental treatment for patients with acute myeloid leukemia.

Participants in this study will receive an infusion of cord-blood progenitor cells after receiving a course of chemotherapy that includes the drugs clofarabine and cytarabine. Patients will also receive granulocyte-colony stimulating factor. The cord-blood infusion may be followed by up to 3 more courses of chemotherapy.

Hematopoietic progenitor cells are cells that give rise to the blood system. The cord-blood progenitor cells will be grown or "expanded" in a laboratory before the infusion takes place. The cord-blood progenitor cells will not be genetically matched with the participant?s tissue type. This study is being done to determine whether or not giving these expanded cells after chemotherapy is safe and helps the blood system to recover more quickly from chemotherapy.

Cytarabine is approved by the Food and Drug Administration (FDA) for use in AML. Clofarabine is approved for use in some pediatric patients with another type of leukemia, called acute lymphoblastic leukemia (ALL).

Participants will receive treatment at the Seattle Cancer Care Alliance (SCCA) and University of Washington Medical Center (UWMC).

The study includes up to 6 months of study treatment for participants who receive all 4 courses of chemotherapy. After that, we would like to maintain follow-up contact for a total of 5 years on study.
