Filter by:The purpose of this study is to reduce the side-effects from anti-leukemia therapy. The therapy in this study is based upon treatment information learned from prior clinical research programs as well as from laboratory research.
This is a Phase II trial to study the safety and tolerability of subcutaneous alemtuzumab administered without dose escalation to patients with advanced B-cell chronic lymphocytic leukemia (B-CLL).
There are naturally occuring variations in the genetic makeup of all of us. Some of these variations may contribute to a change in susceptibility toward different diseases or change the prognosis. We are studying these genetic variations in patients with leukemia. The genes we are studying are those which influence detoxification of drugs and toxins.
The objective of this study is to determine the efficacy and safety of imatinib mesylate in patients diagnosed as having Philadelphia chromosome positive acute lymphocytic leukemia (ALL).
Childhood leukemias which cannot be cured by chemotherapy alone may be effectively treated by allogeneic bone marrow transplantation. Moreover, for patients with chronic myelogenous leukemia (CML), allogeneic hematopoietic stem cell transplantation (HSCT) is the only proven curative modality of treatment. Patients who have received hematopoietic stem cells from an HLA matched sibling donor have proven to be less at risk for disease relapse and regimen related toxicity. However, about 70% of patients in need of HSCT do not have an HLA matched sibling donor. This necessitates the search for alternative donors, which may increase the risk of a poor outcome. The nature of the hematopoietic stem cell graft has been implicated as a primary factor determining these outcomes. The standard stem cell graft has been unmanipulated bone marrow, but recently several advantages of T-lymphocyte depleted bone marrow and mobilized peripheral blood progenitor cells (PBPC) have been demonstrated. However, T-cell depletion may increase the risk of infectious complications and leukemic recurrence while an unmanipulated stem cell graft may increase the risk of graft vs. host disease (GVHD). A key element in long range strategies in improving outcomes for patients undergoing matched unrelated donor (MUD) HSCT is to provide the optimal graft. The primary objective of this clinical trial is to estimate the incidence of acute GVHD in pediatric patients with hematologic malignancies who receive HSCT with an unmanipulated marrow graft. The results of this study can be used as the foundation for future trials related to engineering unrelated donor graft.
This study aims to assess the short term efficacy of a combination immunochemotherapy in patients with relapsed B-cell chronic lymphatic leukemia.
This is a multi-center open label, randomized phase-3 study with stratification according to diagnosis and baseline serum-EPO level. The correction of mild or moderate anemia and the effect on iron kinetics by the rHuEPO treatment with or without intravenous iron supplementation in anemic patients with LPD not receiving antineoplastic therapy will be studied. The study will be performed according to the ICH-GCP guidelines. In order to be eligible, the patient must consent in writing that he/she agrees to participate in the study. The patient recruitment period is estimated to be no longer than 18 months.
Relapsed disease is the most common cause of death in children with hematological malignancies. Patients who fail high-intensity conventional chemotherapeutic regimens or relapse after stem cell transplantation have a poor prognosis. Toxicity from multiple therapies and elevated leukemic/tumor burden usually make these patients ineligible for the aggressive chemotherapy regimens required for conventional stem cell transplantation. Alternative options are needed. One type of treatment being explored is called haploidentical transplant. Conventional blood or bone marrow stem cell transplant involves destroying the patient's diseased marrow with radiation or chemotherapy. Healthy marrow from a donor is then infused into the patient where it migrates to the bone marrow space to begin generating new blood cells. The best type of donor is a sibling or unrelated donor with an identical immune system (HLA "match"). However, most patients do not have a matched sibling available and/or are unable to identify an acceptable unrelated donor through the registries in a timely manner. In addition, the aggressive treatment required to prepare the body for these types of transplants can be too toxic for these highly pretreated patients. Therefore doctors are investigating haploidentical transplant using stem cells from HLA partially matched family member donors. Although haploidentical transplant has proven curative in many patients, this procedure has been hindered by significant complications, primarily regimen-related toxicity including graft versus host disease (GVHD), and infection due to delayed immune reconstitution. These can, in part, be due to certain white blood cells in the graft called T cells. GVHD happens when the donor T cells recognize the patient's (the host) body tissues are different and attack these cells. Although too many T cells increase the possibility of GVHD, too few may cause the recipient's immune system to reconstitute slowly or the graft to fail to grow, leaving the patient at high-risk for infection. However, the presence of T cells in the graft may offer a positive effect called graft versus malignancy or GVM. With GVM, the donor T cells recognize the patient's malignant cells as diseased and, in turn, attack these diseased cells. For these reasons, a primary focus for researchers is to engineer the graft to provide a T cell depleted product to reduce the risk of GVHD, yet provide a sufficient number of cells to facilitate immune reconstitution, graft integrity and GVM. In this study, patients were given a haploidentical graft engineered to with specific T cell parameter values using the CliniMACS system. A reduced intensity, preparative regimen was used to reduce regimen-related toxicity and mortality. The primary goal of this study is to evaluate overall survival in those who receive this study treatment.
The purpose of this study is to find the highest safe dose and to assess the anti-tumor effect of liposomal vincristine with dexamethasone in patients with relapsed or refractory acute lymphoblastic leukemia (ALL).
The purpose of this study is to evaluate the ability of sirolimus to prevent graft versus host disease (GVHD) in patients following stem cell transplant from a related donor.
