Filter by:Evaluate the possible deleterious effects of tyrosine kinase inhibitors on sperm concentration, after 6 months of therapy, which corresponds to 2 cycles of spermatogenesis and on the sperm nuclear integrity. The main comparison criterion will be the mean difference in sperm concentration before and after the 6 month treatment.
This study will assess the pharmacokinetics of nilotinib in Ph+ CML pediatric patients that are newly diagnosed or resistant or intolerant to imatinib or dasatinib or refractory or relapsed Ph+ ALL compared to the adult populations. It will also evaluate safety and activity of nilotinib as secondary objectives.
To investigate whether patients with chronic-phase chronic myeloid leukemia (CP-CML) previously treated with interferon-alpha (IFN) and presently on a tyrosine kinase inhibitor (TKI) (imatinib mesylate, dasatinib, or nilotinib) with achievement of a complete cytogenetic and at least a major molecular remission, are able to discontinue therapy and maintain a durable remission. Relapse-free survival (RFS) rate at 1 year after discontinuation of TKI will be the measurement of this objective.
Patients with refractory hematologic malignancies, including those who develop recurrent disease after allogeneic hematopoietic stem cell transplantation (HSCT) have a dismal prognosis. Historically, both regimen-related mortality and disease recurrence have been significant causes of treatment failure in this heavily pre-treated patient population. Novel therapeutic agents that target molecular signaling mechanisms and increase the sensitivity of leukemic cells to apoptosis may clearly play a role in this setting. This study hypothesizes that interrupting the SDF-1/CXCR4 axis using the selective CXCR4 antagonist plerixafor may be useful as a leukemic stem cell mobilizing agent for patients who are refractory to standard dose chemotherapy and in relapse after an allogeneic transplant. This hypothesis is based on the dependence of leukemia cells on MSCs for survival signals as described above and on the preclinical data that suggest increased efficacy by antileukemia agents when leukemia cells are separated from MSCs. In the present trial, the study proposes to add plerixafor to enhance the conditioning regimen cytotoxicity. At this time the goal is to determine the maximum tolerated dose (MTD) of plerixafor through the process of dose limiting toxicity (DLT) evaluation. Pharmacokinetic studies will be conducted. Additional studies will quantify and the content of leukemia cells and key regulatory and effector T cell populations in the bone marrow and blood before and after exposure to this medication. If the observed outcomes of this trial are promising, it could serve as a platform on which to study further use of plerixafor as a complimentary agent with conditioning as well as other chemotherapeutic regimens for patients with relapsed or refractory hematologic malignancies.
Patients with hematologic malignancies will receive myeloablative chemotherapy followed by stem cell rescue with bone marrow or hematopoietic peripheral blood stem cells collected by apheresis from a filgrastim- (G-CSF)-mobilized haploidentical related-donor, ie, hematopoietic peripheral blood stem cell transplant (HSCT).
To evaluate the major molecular response (MMR) rate at 12 months of nilotinib treatment on study in patients with Philadelphia Chromosome Positive (Ph+) chronic myelogenous leukemia in chronic phase (CML-CP) who have a suboptimal molecular response to imatinib at 18 months or later.
This is a phase I study using Intensity Modulated Total Marrow Irradiation (IM-TMI) in addition to a chemotherapy regimen in preparation for an allogeneic stem cell transplant for advanced hematologic malignancies such as acute myeloid or lymphoblastic leukemia, high grade non Hodgkin's or Hodgkin's lymphoma, chronic myelogenous leukemia, and plasma cell leukemia. Because the subjects participating in this study have a disease that is severe and has a high risk of relapse even after transplant, the investigators propose to use a chemotherapy regimen (fludarabine/busulfan), the name for the combination of chemotherapy drugs that is given to patients prior to transplantation of the donor stem cells, along with intensity modulated radiation (IM-TMI) to the bone marrow. Total body irradiation (TBI) in conjunction with chemotherapy is a standard of care as a pre-conditioning regimen prior to bone marrow transplant (BMT) in patients with hematologic malignancies. However, TBI can cause severe side effects due to irradiation of organs such as the lenses of the eye, whole brain, lungs, liver, kidneys, heart, small bowel and oral cavity. IM-TMI allows for the delivery of adequate doses of radiation to the bone marrow while sparing other organs and therefore limiting radiation side effects. The irradiation, along with receiving the chemotherapy drugs will suppress the subject's immune system and kill off tumor cells, but will also intensify the effect of the conditioning regimen thus allowing the bone marrow transplantation to have a greater chance of being successful. No investigational drugs are used in this study. The investigational part of this study is the use of intensity modulated total marrow irradiation instead of conventional radiation. IMTMI can deliver 99% of the prescribed treatment to the targeted bones and reduce the doses of radiation to surrounding organs, as received in conventional TBI, by 29% to 65%.
The primary purpose is to determine the ability of CD34+ selection and T cell depletion using the CliniMACS® device to prevent severe acute graft-versus-host disease (GVHD) in patients receiving a stem cell transplant from an alternative (unrelated and mismatched related) donor. The secondary objectives include evaluation of engraftment, immune recovery, and post-transplant infections. Patients requiring stem cell transplants for either malignant (cancerous) or non-malignant disease will be included in the study. The recipients will be grouped into one of two groups based on whether the donor is mismatched related (Cohort A) or unrelated (Cohort B). The patient will receive a conditioning regimen including chemotherapy drugs and/or total body irradiation based on the disease for which the transplant is performed.
Dendritic cell therapy is a promising strategy for adjuvant cancer therapy in the setting of minimal residual disease (MRD) to fight off cancer relapse and/or progression. The investigators already performed a phase I safety study in leukemia patients that were in complete remission demonstrating the absence of side effects and feasibility of the therapy. Here, the investigators want to extend on this strategy by studying the clinical efficacy of autologous DC vaccination in patients with acute and chronic myeloid leukemia and myeloma patients. Effects of DC therapy on the immune reactivity towards leukemia cells as well as clinical parameters such molecular MRD monitoring, time to relapse (TTR), progression-free survival (PFS) and overall survival(OS) will be studied in vaccinated and non-vaccinated (control) patients. Patients will be vaccinated using their own dendritic cells electroporated with mRNA coding for the full-length Wilms' tumor antigen WT1.
The purpose of this study is to find out if the level of imatinib in the bloodstream, and the level that leukemia cells will predict how quickly your chronic myeloid leukemia improves with the treatment. 1.1 Primary Objectives To determine if intracellular levels of Imatinib in leukemic blood cells within two weeks of treatment initiation of patients with chronic myeloid leukemia in chronic phase predicts molecular and cytogenetic response at 6 and 12 months post treatment 1.2. Secondary Objectives 1.2.1 To determine if hOCT-1 mRNA levels at diagnosis predict Imatinib intracellular levels within two weeks of treatment initiation. 1.2.2 To determine the correlation between intracellular Imatinib levels at two weeks of treatment initiation with plasma Imatinib levels at two and four weeks after treatment initiation. 1.2.3 To determine if plasma Imatinib levels four weeks after treatment initiation correlate with plasma Imatinib levels 12 months after treatment initiation. 1.2.4 To determine if intracellular levels of Imatinib in leukemic blood cells within two weeks of treatment initiation correlate with intracellular levels of Imatinib in normal leukocytes 12 months after treatment initiation.
