Filter by:The goal of this clinical research study is to learn if it is safe and feasible to transplant patients with one of two units of cord blood that has been changed in the laboratory before it is given. Only patients with leukemia, lymphoma or myelodysplastic syndrome will be allowed on this study. The secondary goal is to obtain the preliminary efficacy outcome. Researchers also want to learn if using cord blood that has been changed can help to control the disease. One cord blood unit will not be changed before it is administered to you. The cord blood unit that will be altered will be changed to use sugar that is found in small amounts in blood cells. It plays a role in telling transplanted cells where they should go in the body. Adding more sugars to the cord blood cells in the laboratory helps the cord blood cells find their way to the bone marrow faster. This process is called fucosylation. "Conditioning" is the chemo and other medicines and will be given to patients to prepare to receive cord blood transplant cells. This prevents immune system from rejecting the cells. Conditioning will be started before the transplant. ATG is a protein that removes immune cells that cause damage to the body. Clofarabine is designed to interfere with the growth and development of cancer cells. Fludarabine is designed to interfere with the DNA of cancer cells, which may cause the cancer cells to die. This chemotherapy is also designed to block your body's ability to reject the donor's bone marrow cells. Melphalan and busulfan are designed to bind to the DNA of cells, which may cause cancer cells to die. MMF and tacrolimus are designed to block the donor cells from growing and spreading in a way that could cause graft versus host disease (GVHD -- a condition in which transplanted tissue attacks the recipient's body). This may help to prevent GVHD. Rituximab is designed to attach to cancer cells, which may cause them to die. A Phase I study for treatment of patients (N=25) with hematologic malignancies and MDS who are candidates for dual-cord UCBT is ongoing at M.D. Anderson Cancer Center under an Investigator-initiated IND Application, E.J. Shpall, MD, PI. Since August, 2012, Preliminary results indicate that ASC-101 UCBT is well-tolerated and no ASC-101 related untoward adverse events have been observed. To date, the median time to neutrophil engraftment (N=9) is 15 days, and the median time to platelet engraftment (N=9) is 33 days. The trial remains ongoing.
This is a phase II, prospective, multicenter, open-label study to evaluate the efficacy and safety of Alemtuzumab in patients with relapse and refractory B-cell chronic lymphocytic leukemia.
The primary objective of this study is to evaluate the progression-free survival in participants with previously untreated chronic lymphocytic leukemia (CLL) who would otherwise be suitable for bendamustine and rituximab treatment as standard of care. An increased rate of deaths and serious adverse events (SAEs) among participants with front-line CLL and early-line indolent non-Hodgkin lymphoma (iNHL) treated with idelalisib in combination with standard therapies was observed by the independent data monitoring committee (DMC) during regular review of 3 Gilead Phase 3 studies. Gilead reviewed the unblinded data and terminated this study in agreement with the DMC recommendation and in consultation with the US Food and Drug Administration (FDA).
The primary objective of this study is to evaluate the effects of idelalisib with obinutuzumab versus the combination of chlorambucil and obinutuzumab on progression-free survival (PFS) in participants with previously untreated chronic lymphocytic leukemia (CLL). An increased rate of deaths and serious adverse events (SAEs) among participants with front-line CLL and early-line indolent non-Hodgkin lymphoma (iNHL) treated with idelalisib in combination with standard therapies was observed by the independent data monitoring committee (DMC) during regular review of 3 Gilead Phase 3 studies. Gilead reviewed the unblinded data and terminated those studies in agreement with the DMC recommendation and in consultation with the US Food and Drug Administration (FDA). All front-line studies of idelalisib, including this study, were also terminated.
This Phase I trial studies the safety and efficacy of vaccine therapy in treating patients with previously untreated chronic lymphocytic leukemia. Liposome-based vaccines containing an extract of a person's cancer cells and the immunostimulant interleukin-2 may help the body to build an effective immune response to kill cancer cells.
The purpose of this study is to determine whether a novel standard of care protocol, washing red cell and platelet transfusions for younger patients with acute leukemia, has yielded improved clinical outcomes at Strong Memorial Hospital (Rochester, New York, USA). This standard of care was implemented based upon an earlier randomized trial (BMC Blood Disorders. 2004 Dec 10;4(1):6) The comparator will be historical controls from the medical literature.
LGL leukemia represents a rare subtype of chronic T or NK lymphoproliferative disorders. It is an indolent disease, the main hematological or autoimmune complications lead to a treatment in more than 60% of patients. Investigators set up at the University Hospital of Rennes, a database of more than 300 patients with LGL leukemia from major French services that support this disease, and published in 2010 the largest series of patients in the world (n = 229). However, the limited heterogeneity and retrospective data collected, as all previously released, makes it difficult the proposal of consensual treatment options. If first and second line treatments are based on the use of immunosuppression with methotrexate, cyclophosphamide, or cyclosporin A, no molecule has proven superiority over others. Methotrexate and cyclophosphamide are mainly used in the first line. Invetigators just have in the literature data on about 100 patients treated with either of these drugs. Combining the results of our series with those in the literature, invetigators estimate the respective overall response rate (RG) and complete response rate (CR) in 55% and 30% for methotrexate, and 60% and 50% for cyclophosphamide. Thus, there are four objective in this study : 1. to compare the respective efficacies of methotrexate and cyclophosphamide when administered as first-line therapies in patients suffering from T/NK LGL leukemia with severe neutropenia or neutropenia associated with infections, and/or anemia requiring transfusions, and/or auto-immune associated disease 2. to evaluate the percentage of patients refractory to methotrexate or cyclophosphamide for which a second line treatment is efficacious 3. to explore, in case of non-response to the first-line therapy, the efficacy of ciclosporine A, the comparison being performed with the treatment which was not administered in the first-line therapy 4. to evaluate the response rate according to the phenotypic subtype of LGL leukemia.
Modern therapy for patients with B-lineage acute lymphoblastic leukemia (ALL) is based on intensive administration of multiple drugs. In patients with relapsed disease, treatment response is generally poor; for most patients, particularly those who relapse while still receiving frontline therapy, the only therapeutic option is hematopoietic stem cell transplantation (HSCT). There is no proven curative therapy for patients who relapse after transplant. Natural killer (NK) cells have powerful anti-leukemia activity. In patients undergoing allogeneic HSCT, several studies have demonstrated NK-mediated anti-leukemic activity. NK cell infusions in patients with leukemia have been shown to be well tolerated and void of graft-versus-host disease (GVHD) effects. NK cell cytotoxicity is most powerful against acute myeloid leukemia (AML) cells, whereas their capacity to lyse ALL cells is generally low. We have developed a novel method to expand and redirect NK cells towards CD19, a molecule highly expressed on the surface of B-lineage ALL cells but not expressed on normal cells other than B-lymphocytes. In this method, donor NK cells are first expanded by co-culture with the cell line K562-mb15-41BBL and interleukin (IL)-2. Then, the expanded NK cells are transduced with a signaling receptor that binds to CD19 (anti-CD19-BB-zeta). NK cells expressing these receptors showed powerful anti-leukemic activity against CD19+ ALL cells in vitro and in an animal model of leukemia. This study will assess the feasibility, safety and efficacy of infusing expanded, activated redirected NK cells into research participants with B-lineage ALL who have persistent disease after intensive chemotherapy . In this same cohort, we will study the in vivo lifespan and phenotype of these redirected NK cells.
The purpose of this study is to evaluate the efficacy and safety of ibrutinib versus rituximab in adult Asia Pacific region patients with relapsed or refractory chronic lymphocytic leukemia (CLL) or small lymphocytic lymphoma (SLL).
The present trial will be performed according to an open design to determine the maximum tolerable dose (MTD) by evaluation of dose-limiting toxicity (DLT) of volasertib in paediatric leukaemia and solid tumours in the age group 2 to less than 12 and 12 to less than 18 years. A further objective is to collect data on safety, tolerability, toxicity, efficacy (preliminary activity), pharmacokinetics and pharmacodynamics of volasertib in paediatric cancer patients
