Active clinical trials for "Leukemia"

This is a phase II therapeutic study of related donor HLA-haploidentical NK-cell based therapy after a high dose of fludarabine/cyclophosphamide with denileukin diftitox preparative regimen for the treatment of poor prognosis acute myelogenous leukemia (AML).

Time-to-Progression (TTP)

The purpose of this study is to evaluate the multi-lineage hematopoietic chimerism for unrelated umbilical cord blood (UCB) grafts pooled from two to three cord blood units. Also to evaluate the toxicity, and antitumor responses of pooled unrelated UCB transplants.

The primary objective of the trial is to compare the two-year relapse-free survival (RFS) of patients with acute myeloid leukemia (AML), presumed to be at high risk for relapse due to the presence of leukemia stem cells (LSCs) in their bone marrow at first complete remission (CR1), who receive either standard cytarabine-based chemotherapy or allogeneic stem cell transplantation (SCT).

The purpose of this study is to establish toxicity and a maximum tolerated dose recommended phase 2 dose of Clofarabine in combination with Etoposide and Mitoxantrone for therapy of relapsed or refractory acute leukemias. The investigators will observe responses with these therapy agents and assess the impact of Clofarabine interacting with Etoposide in induction of DNA strand breaks.

This study will collect tumor samples from people with cancers of the blood, bone marrow, or lymph glands for laboratory study of the biology of these conditions. Such studies contribute to a better understanding of cancer biology and to the development of new treatments. Planned studies include: Examination of individual cancer cells and to search for differences compared to other types of cancer and normal cells Examination of the chromosomes and genes in cancer cells and to search for differences compared to other types of cancer and normal cells Development of sensitive methods to detect small amounts of cancer that remain after treatment Search for new cancer proteins that might serve as targets for treatment Investigation of methods to develop cancer vaccines. Patients from >= 1 to 75 years of age with acute lymphocytic leukemia, acute myelogenous leukemia, myelodysplastic syndrome, chronic myelogenous leukemia, juvenile myelomonocytic leukemia, non-Hodgkin's lymphoma, Hodgkin's disease, and other hematologic malignancies may be eligible for this study. Blood or bone marrow samples will be collected when sampling is required for the patient's medical care. Cells from some individuals will be grown in test tubes, establishing cell lines or in animals, establishing xenograft models. (A xenograft is transplantation of cells of one species to another species.)

This study will determine the activity of decitabine, low dose cytarabine (ARA-C) and G-CSF for patients with myelodysplasia and leukemia.

A Notch signalling pathway inhibitor study in pediatric and adult patients with relapsed (worsening) or refractory (not responding to treatment) T-cell acute lymphoblastic leukemia/lymphoma (T-ALL).

This observational study aims to assess recovery of the immune system and immunity to vaccine-preventable diseases in children and adolescents who recently completed treatment for acute lymphoblastic leukemia (ALL). Several children's hospitals in the United States are participating in the study, which will enroll approximately 75 pediatric participants. The study is intended to determine the rate of infection after leukemia treatment and to inform future studies and recommendations about whether children and adolescents who have leukemia should receive additional vaccine doses or boosters after treatment.

An observational, prospective study to describe the rates and predictors of cardiovascular events in patients with acute leukemia.
