Active clinical trials for "Leukemia, Lymphoid"

The aim of this study is to assess JL1 expression by flow cytometric immunophenotyping in patients with B-cell Acute Lymphoblastic Leukemia (ALL) and to correlate it with clinical, morphological, immunophenotypic, cytogenetic data and response to treatment.

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.

Time-to-Progression (TTP)

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.)

Escalating doses of Omega 3 Fatty Acids are being used in patients who have early stage Chronic Lymphocytic Leukemia (ES-CLL), Monoclonal Gammopathy of Undetermined Significance (MGUS), or Smoldering Multiple Myeloma (SMM), whose disease does not currently require treatment. The primary aim of the study is to determine if the Omega 3 supplementation will help prevent or delay progression of the disease to a stage that requires treatment.

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.

Recent data have shown that the inadequate vitamin D status plays a role in the manifestation of the haematologic tumors and serum vitamin D level has a prognostic role also as it determines the tumor mortality. But data have not proved a causal relationship between the inadequate vitamin D status and the unfavourable outcomes so far. It is also still unknown, whether the normalization of vitamin D status in patient with vitamin D inadequacy is able to improve the prognosis and survival. In this study the investigators examine the role of the adequate vitamin D substitution in the improvement of the outcomes of haematologic disorders.

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

This is a multicenter open-label phase II trial of trastuzumab in patients with HER2 positive B-ALL in relapse, or with refractory disease. Herceptin is administered as a 4 mg/kg intravenous loading dose followed by 2 mg/kg weekly for at least 2 months and/or till progression. Response and HER2 expression are assessed each month by bone marrow aspirate.

This is a randomized (1:1), open-label, multicenter, active-controlled study in patients with previously treated CD23+ and CD20+ relapsed CLL. Patients will receive treatment with either lumiliximab in combination with FCR or FCR alone.
