Expanded Cord Blood Cell Infusion Following Combination Chemotherapy in Younger Patients With Relapsed or Refractory Acute Myeloid Leukemia

NCT01701323

Description:

This pilot clinical trial studies infusion of expanded cord blood hematopoietic progenitor cells following combination chemotherapy in treating younger patients with acute myeloid leukemia that has relapsed or has not responded to treatment. Chemotherapy drugs work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Chemotherapy also kills healthy infection-fighting cells, increasing the risk of infection. The infusion of expanded cord blood hematopoietic progenitor cells may be able to replace blood-forming cells that were destroyed by chemotherapy. This cellular therapy may decrease the risk of infection following chemotherapy.

Eligibility Criteria

        Inclusion Criteria:

          -  Patients must have a diagnosis of AML or acute leukemia of ambiguous lineage according
             to World Health Organization (WHO) classification with >= 5% of disease in bone marrow
             (BM)

          -  Recipients of prior allogeneic hematopoietic stem cell transplantation for AML or
             acute leukemia of ambiguous lineage are eligible if they do not have graft-versus-host
             disease (GVHD) or they have quiescent GVHD whether or not they are receiving
             immunosuppressive therapy

          -  Must have a Lansky or Karnofsky performance status of >= 50; use Karnofsky for
             patients > 16 years of age and Lansky for patients =< 16 years of age

          -  Patients must have recovered from the acute toxicity of all prior chemotherapy

          -  The following amounts of time must have elapsed prior to entry on study:

               -  2 weeks from local radiation therapy (XRT)

               -  8 weeks from prior craniospinal or if > 50% of the pelvis has been irradiated

               -  6 weeks must have elapsed if other bone marrow radiation has occurred

          -  Adequate cardiac, renal, pulmonary, and hepatic function

          -  Patient must have a life expectancy of at least 2 months

          -  Females of childbearing potential must have a negative serum pregnancy test performed
             within 7 days prior to the start of treatment

          -  Females of childbearing potential and males should agree to use adequate contraception
             (barrier method of birth control) prior to study entry and for the duration of study
             participation

        Exclusion Criteria:
